- ItemOpen AccessAbutments and periodontal parameters in prospective denture wearers(Afr J Med Sci, 2021) AKINBOBOYE B.OIntroduction: Dentures are common tooth replacement option and they may pose an increased periodontal risk to abutment teeth resulting in premature tooth loss. Aims and Objectives: To determine if a difference exists between periodontal parameters of abutment teeth, and non-abutment teeth on the same of the edentulous area in prospective denture wearers. Materials and methods: Consecutive partially edentulous patients demanding for removable partial denture were selected. Interviewer-administered questionnaires were used and examination done with dental instruments - mouth mirrors, dental explorers and periodontal probes. Selected non-abutment teeth were adjacent to the abutment teeth on the same arch. Plaque assessment and periodontal pocket depths were done on the four surfaces (buccal, lingual, mesial and distal) of all abutment and non-abutment teeth excluding third molars. Probing depth estimated to the nearest minimum was recorded for the selected teeth, and data collected was analyzed with IBM SPSS 20. Student t tests and ANOVA were utilized. Results: Sixty-one participants with mean age of 60.9 ± 14.27 years, and age range from 21to71 years were seen. Thirty-six (59%) were male. Majority (96.8%) brushed with toothbrush only, 51.5% brushed once a day and 57.4% had Kennedy class III edentulous arches. Mean probing depth of abutment (2.40 ± 0.16 mm) and non-abutment teeth (2.24 ± 0.15 mm) varied significantly (p <0.001). Majority of those who brushed once daily and those who had Kennedy Class III edentulous spaces had poor Oral Hygiene (p <0.0001, p=0.03 respectively). Differences in the probing depth of abutment (F=0.46), non-abutment teeth (F = 1.11) and oral hygiene (F = 1.13, p=0.71, p=0.35, p = 0.34 respectively). Correspondence: Dr. B.O. Akinboboye, Department of Restoratve Dentistry, Faculty of Dental Sciences, University of Lagos, Lagos, Nigeria. E-mail: bakinboboye@unilag.edu.ng Conclusion: Abutment teeth of edentulous spaces had poorer periodontal status than non-abutment teeth, suggesting increased risk for periodontal disease for prospective abutment teeth. Greater attention should therefore be given to these abutment teeth during oral hygiene measures in denture wearers. Location of edentulous space on dental arch have significant relationship with oral hygiene status.
- ItemRestrictedAwareness of dental implants among dental patients in Nigeria(2016-06) Ajayi, Y O; Dosumu, O O; Akeredolu, PA; Akinboboye, B OThe aim of this study was to determine the level of awareness of dental implant in Nigerian patients and their willingness to choose dental implant as a tooth replacement option A survey was conducted among patients presenting for dental treatment in 3 teaching hospitals and private dental clinics in 3 urban cities of Nigeria using a self-administered questionnaire. A total of 294 out of 325 questionnaires were returned completely filled. 39.8% of the respondents have knowledge of dental implants as tooth replacement option. 35% and 26.5% are willing to choose implant for replacement of missing anterior and posterior teeth respectively. Patients with high level of education are significantly better informed on implants as a method of tooth replacement. The major source of information is the dentist (41.5%) followed by friends (17.7%). The level of awareness of dental implants was low despite the high level of education of the respondents. Willingness to choose implant as tooth replacement option was low due to high cost of dental implants and the need for surgery.
- ItemOpen AccessComparison of the dimensional stability of alginate impressions disinfected with 1% sodium hypochlorite using the spray or immersion method(Nig Quarterly J Hosp Med, 2007) Oderinu, OH; Adegbulugbe, IC; Shaba, OPObjective: To determine and compare the dimensional stability of alginate impressions disinfected with Sodium hypochlorite using the spray and immersion methods. Methodology: Alginate impressions of a master model of truncated metal cones were made and disinfected with 1% sodium hypochlorite constituted from 3.5% household bleach using the spray and immersion technique for 10;20 and 30 minutes. Impressions were cast in dental stone and the linear dimensional differences between the inter-abutment distances were measured with an electronic caliper. One sample T test and percentage differences were calculated. Result: There were no statistically significant differences in dimensions of alginate impressions of the control and those disinfected by either spraying or immersion methods when compared with the master model at 10 minutes. However, there was a statistically significant difference at 20 and 30 minutes. The spray technique showed the least percentage difference from the master model. Conclusion: Disinfection of alginate impressions with 1% sodium hypochlorite constituted from commercially available household bleach by the spray or immersion techniques for ten minutes will produce casts with minimal dimensional changes.
- ItemOpen AccessComparison of the incidence of flare-up and time efficiency in single visit root canal treatment employing either rotary or manual step-back canal preparatory technique(Nigerian Postgraduate Medical Journal, 2018) Makanjuola, JO; Umesi, DC; Oderinu, OHAim: This study aims to compare the incidence of flare-up and operating time in root canal treatments where rotary or manual step-back canal preparatory technique was employed. Materials and Methods: A randomised study was conducted in a Nigerian Teaching Hospital. One hundred and twenty teeth belonging to 95 patients were randomised into two (Rotary and Manual) groups. Root canal treatment was performed using either rotary or manual step-back canal preparatory technique. Canal preparation time and total operating time were measured. Patients were monitored for severe pain and/or swelling over 1-week. Data were analysed using SPSS version 20.0, at alpha-level of P ≤ 0.05. Chi-square and independent Student's t-test were employed for comparison where categorical and numeric variables were involved, respectively. Results: There was neither associated pain/swelling before treatment in 28 (46.7%) of the teeth in rotary group nor in 27 (45.0%) of the teeth in manual group. Pain incidence was 11.7% and 16.7% in rotary and manual groups, respectively, at 1-week review. Severe pain was experienced by 3.3% patients in both groups at 1-week review. Only 1.7% and 6.7% in rotary and manual groups, respectively, presented with swelling over 1-week. Flare-up incidence at 1-week review was 3.3% in rotary and 8.3% in manual groups, the difference was not significant (P = 0.243). Canal preparation and total operating times were significantly shorter (P < 0.05) in the rotary group in all tooth categories. Conclusion: No significant difference was noted in flare-up incidence between rotary and manual groups. Canal preparation time and total operating time were significantly shorter for rotary technique. Time efficiency is clinically invaluable, especially for multi-rooted teeth.
- ItemOpen AccessCONTINUING PROFESSIONAL DEVELOPMENT IN IMPLANT DENTISTRY AMONG NIGERIAN DENTISTS(2019-06) Ajayi, Y O; Oremosu, O A; Umesi, D CThe practice of implant dentistry is low in Nigeria. Continuing Professional Development (CPD) help dentists to keep up to date with new scientific knowledge and integrate the learned skill into safe clinical practice.The aim of this study is to determine the level of exposure to Continuing professional development in implant dentistry amongst Nigerian dentists. A cross sectional study was carried out amongst dentists drawn from all geopolitical zones of Nigeria who were attending a dental update course including the dental house officers present in the institution where the update course took place. A structured self administered questionnaire was used to elicit information on their knowledge of different providers of CPD and assessment of CPD in implant dentistry in Nigeria, dental implant treatment experience,undergraduate exposure to dental implant education and continuing professional development in implant dentistry among respondents. Data was analysed with statistical package for social Sciences software version 17 (SPSS, Chicago, IL). A total of 110 respondents, comprising of 55.5% males and 44.5% females participated in the study. The mean age was 33.5(±7.4) years. Undergraduate exposure to implant dentistry was mostly by lectures 91(82.7%), the most common postgraduation exposure to implant training was live demonstration (49.1%) followed by organized short courses (28.2%). The largest CPD providers were private organizations 41(37.3%) and the National/local dental association 39(35.5%). Majority (82.7%) of the respondents had not received CPD on implant dentistry. This indicated a low level of exposure.There is therefore a need for well structured CPD courses on implant dentistry to be made available
- ItemOpen AccessDens Invaginatus: Prophylactic Management(Nig Dental Journal, 2007) Oderinu, OH; Adegbulugbe, IC; Agbaje, LODensinvaginatus is thought to be asa result of distortion of the enamel organ during tooth development and the subsequent protrusion of a part leading to the formation of a linear enamel canal that ends at the cingulum, or at the incisal border, producing an irregular crown shape. food debris may become packed in this area with resultant caries and pulp necrosis and periradicular inflammation. The permanent maxillary lateral incisors are the most commonly involvedteeth and bilateral involvement is not unusual. Case Report This is a report of bilateral involvement of the maxillary incisors with associated carious involvement of the coronal pits in a 43year old man with a high caries index. Composite filling of the palatal pits of the involved teeth was done as a prophylactic treatment to prevent carious exposure of the pulp and subsequent periradicular pathology. Conclusion. Prophylactic filling of the coronal pit is recommended to avoid pulpal and periradicular complications that may warrant extensive and expensive treatment or even loss of the involved tooth.
- ItemOpen AccessDental Implant Education in Nigeria: A curriculum Guide(Niger Postgrad Med J 2007, 2007) Adeyemo, W.L.; Akeredolu, P.A.; Oderinu, H.O.; Olorunfemi, B.O.Aim: Anecdotal evidence suggests that the practice of implant dentistry, "gold standard" for edentulism is presently very low in Nigeria. This article proposes a model for teaching dental implant education and also emphasises the need for inclusion of standardised dental implant education in the dental curriculum in Nigeria. Methods: A literature search using the MEDLINE was conducted on various models for teaching of dental implant education worldwide. Results: Implant dental education for undergraduate and postgraduate programmes has 3 components namely: didactic educational programme, laboratory hands-on experience, and clinical hands-on experience. In addition, dentists and dental educationists can gain proficiency in basic and advanced implant dentistry through implant dental education organised by recognised universities, private and international implant organisations, manufacturersponsored educational programmes as well as training and courses organised by dental associations. Conclusions: Dental implant education should be given a priority and be included in both the undergraduate and postgraduate dental curriculum in Nigeria. In addition, a standardised implant dentistry programme should be formulated and developed for all dental schools in Nigeria.
- ItemOpen AccessDental students' knowledge of human immunodeficiency virus(Journal of Dentistry Elsevier, 2008-03) Ajayi, Y.O.; Ajayi, E.O.OBJECTIVE: This study evaluated final year dental students' knowledge of human immunodeficiency virus (HIV), lesions associated with HIV, potential transmission routes of HIV, and their perception of the teaching received on cross-infection precautions, virology, sterilization practice and procedure, barrier dentistry and recognition of blood-borne virus risk group. METHODOLOGY: Structured questionnaires on knowledge of human immunodeficiency virus were filled by final year dental students of University of Lagos, Nigeria. A total of 35 out of 37 questionnaires were returned filled giving a response rate of 94.6%. RESULTS: Most of the students rated the teaching they received on cross-infection precautions, sterilization practice and procedure, as adequate. More than a quarter (28.5%) of the students rated the teaching they received on virology and recognition of blood-borne virus risk group to be less than adequate. Most of the students were able to recognize the association of oral Kaposi sarcoma, oral candidiasis, oral hairy leukoplakia, and salivary gland enlargement with HIV infection. There was a much lower level of knowledge of oral melanotic hyperpigmentation and idiopathic thrombocytopaenic pupura. Their knowledge of HIV and its potential transmission routes were adequate. CONCLUSION: This study revealed that final year dental students of the University of Lagos in southwestern region of Nigeria had adequate knowledge of routes of transmission of HIV in clinical practice. However, there is need for improvement in teaching of the students on virology and recognition of blood-borne virus risk group.
- ItemOpen AccessDescriptors of permanent teeth with cariously exposed pulp in patients presenting at a Nigerian hospital(Acta Odontologica Scandinavica, Taylor& Francis informa, UK, 2013-02-04) Ajayi, Y.O.; Sofola, O.O.Aim. To describe the pattern of presentation of carious permanent teeth with pulp exposure and to determine factors associated with choice of treatment for such teeth. Materials and methods.All patients presenting at the oral diagnosis clinic of Lagos University Teaching Hospital Dental centre between January 2009 and June 2009 were examined and those with carious lesion involving the pulp were included in the study. The history and character of pain from teeth, extent of tooth structure lost, proposed treatment and reason for proposed treatment was recorded. Results. The tooth most affected by pulp exposure due to caries is the lower first molar (17.5%). Extraction was the treatment of choice for many patients due to the following reasons: obliterated root canals (30%), patients' preference (30%) and non-restorable teeth (22%). Conclusion. Extraction was the predominant treatment chosen for cariously exposed permanent teeth due to the condition of the tooth.
- ItemOpen AccessThe effect of implant characteristics on the implant stability of immediately loaded single implant cases: A prospective study(2018) Obagbemiro, K; Ajayi, Y O; Akeredolu, P A; Adeoye, JA; Arotiba, GTIntroduction: Factors that affect primary and ultimate implant stability include characteristics of the type of dental implant used, bone quality at the site of implant placement, insertion torque, as well as micromotions at the bone–implant interface. This study, however, sought out to determine the effect and relationship between relevant implant characteristics and implant stability in immediately loaded single implant cases using the Periotest® M handheld device. Aim: To determine the effect of implant characteristics on the ultimate implant stability in immediately loaded single implant cases. Results: At placement, 33 (94%) of implants had periotest values between −0.8 and 0 at placement. There is a general decrease in the number of patients with periotest values −0.8–0 and those with +1–9 from the initial placement to 6 months after placement. It was further observed that there is a negative correlation between the implant length, diameter, and the mean periotest values although this was not statistically significant. Conclusion: There is a directly proportional relationship between implant characteristics and implant stability of immediately loaded implants.
- ItemOpen AccessEndodontic patients' profile and experience in a dental school setting(2012-12) Ajayi, Y.O.; Gorduysus, O.The aim of this study was to assess patient's previous experience of endodontic treatment and satisfaction with the present endodontic treatment received in a dental school setting. A questionnaire on previous and present endodontic experience was administered to 83 consecutive patients receiving endodontic treatment between January 2010 and June 2010 in the Department of Restorative Dentistry of Lagos University Teaching Hospital (LUTH). 82% of the patients seen preferred root canal treatment (RCT) to extraction. 88% were satisfied and rated their treatment and the clinic average to very good. 61.5% reported that they would definitely recommend endodontic treatment to others. 9 (10.8%) patients reported that they would never recommend endodontic treatment. 8 out of the 9 patients experienced pain during the endodontic treatment. Patients' expectation of their tooth being preserved by root canal treatment was met by the LUTH dental centre. Patients' dissatisfaction with endodontic treatment is associated with a painful experience.
- ItemOpen AccessEvaluation of Aesthetic Outcome of Single Tooth Implant Borne Restoration(2018-05) Ajayi, Y O; Akinboboye, B OObjective: To evaluate aesthetic outcome of single dental implants placed in anterior and premolar area of dental arches using the pink and white aesthetic scores. Methods: Twenty-nine implants placed in the anterior and premolar region for single tooth replacement in 20 patients were evaluated. The patients were treated with single dental implants (6-8mm length bicon implant) that supported porcelain fused to metal crowns. Aesthetic outcome was evaluated a year after placement of dental implant, by assessing both clinical and photographed implant crowns with the contralateral teeth. The pink aesthetic score and white aesthetic score (PES & WES) were used to assess the aesthetic outcome. Results: Twenty nine implants were placed in 20 patients (9 males and 11 females); six implants were immediate placements. A year after placement, all the implants had integrated with healthy peri-implant soft tissues according to standard clinical parameters. The mean score for pink aesthetics score was 8.9± 1.47 (range 6-12). Gingiva texture (1.76±0.44) had highest mean score and the least mean score was for scar (1.10±0.49). The mean for White aesthetic score was 7.76±1.35 (range 5-10) with tooth volume having highest mean score as 2. and least mean score for characterization (1.03±0.42). The mean total pink aesthetic score/white aesthetic score was 16.66 on a maximum of 22. Conclusion: The objective assessment of aesthetic outcome using PES/WES index reveals that implant placement at aesthetic zone was successful. Guided tissue regeneration may be necessary to achieve a satisfactorily level of gingiva.
- ItemOpen AccessEvaluation of Linear Dimensional Stability of Various Combinations of Dental Stone and Plaster(Nig Quarterly J Hosp Med, 2011) Adegbulugbe, IC; Oderinu, OH; Shaba, OP; Oremosu, OABackground: It has been observed that due to the cheaper cost of dental plaster compared to dental stone, casts on which most of the dental prostheses and appliances were being fabricated in various laboratories were often mixtures of dental stone and dental plaster in order to reduce production cost. Objective: To evaluate the dimensional stability of various combinations of Dental Stone and Dental Plaster mixtures used to make dental casts. Methods: Alginate impressions of a master model of truncated metal cones were made and casts were produced by pouring with various combinations of dental stone and dental plaster mixtures. The linear dimensional differences between the inter-abutment distances on the casts were measured with an electronic calliper. One sample t-test and percentage differences were calculated. Results: Dimensional variations for the distances measured using either 50% dental stone or 25% dental stone with plaster were statistically significant (p d" 0.05). Mixture of 75% dental stone and 25% dental plaster produced casts with no statistically significant dimensional variation from the master model (p en0.05). Conclusion: A mixture of 75% dental stone and 25% dental plaster could be used for procedures not requiring very accurate replica like mounting of teeth for dental training and for study models.
- ItemOpen AccessEvaluation of short term survival rate of immediate loading of single implant cases in Nigerian subjects : A longitudinal study(2019-06) Obagbemiro, K; Ajayi, YO; Adeoye, JA; Akeredolu, P A; Arotiba, G TObjective: Dental implant therapy is fast becoming the most popular treatment option for replacing missing teeth. The original protocol for its placement advocates leaving the implant unloaded for a three to six-month period before placing the prosthesis. In more recent times, loading implants right after they are placed within the bone have been achieved, offering several advantages to the patients. This study aims to evaluate the one-year survival rate of immediately loaded dental implants. Materials and methods: This prospective, longitudinal and interventional study evaluated the one-year survival rate of immediately loaded single dental implants cases in 35 subjects that were rehabilitated using the one stage implant protocol. Subject follow up was done for at intervals over a one-year period with data collected at each visitation. Analysis of data gathered was done using Statistical Package for the Social Sciences software (SPSS) version 22 (IBM Corp, Armonk, NY, USA). Results: A cumulative survival rate of 80% was obtained with 28 out of 35 implants surviving after the one-year review period. All mandibular implants survived while a survival rate of 72% obtained in the maxilla. Furthermore, 87.5% of immediately loaded implants placed in the posterior region survived, which is higher than the 73.7% implant survival rate observed in the anterior region. Conclusion: Provided the conditions are favourable for its use, immediately loaded implant protocol should be considered as the protocol has a one-year survival rate that compares favorably with the conventional protocol for implant placement.
- ItemOpen AccessEvaluation of the use and effectiveness of telemedicine among the health professionals during the COVID 19 lockdown period: A cross sectional study.(J Clin Sci, 2021) AKINBOBOYE B OBackground: Telemedicine has been documented as a viable option in attending to patient’s need where distance is a critical factor. The Federal Government of Nigeria on March 27, 2020, imposed a total lockdown in Lagos state in orderto curb the spread of the coronavirus disease 2019 (COVID 19) pandemic. The restriction in movement prevented many patients from attending their regular clinics and physical consultations. The aim of this study was to evaluate the use and effectiveness of telemedicine among the hospital health professionals during the lockdown period. Methods: This was an online cross sectional study among doctors at a tertiary health facility in Lagos. Ethical approval was obtained from the institutional ethical committee. A list of the telephone and WhatsApp contacts of doctors were obtained from the hospital directory; the SurveyMonkey tool was used as an online web based structured questionnaire for data collection. The information obtained was analyzed to find means and averages. Results: A total of 104 doctors completed the survey. The proportion of participants who used telemedicine was 93.3%, with the most commonly used telemedicine option being phone call (27.1%) and WhatsApp video call (27.1%). The main management provided during this period was counseling (56.6%). Seventy nine percent of the participants were satisfied with the result of the management provided through telemedicine options, but the major concern was that of ethical issues (36.2%). Majority (44.2%) of the respondents agree that telemedicine was effective during the COVID 19 lockdown period. Therewas no association found between gender, age, designation, and perceived effectiveness of telemedicine by respondents in this study (P = 0.88, 0.4, and 0.07, respectively). Conclusion: Telemedicine was found to be a useful tool for effective patient’s management during the lockdown period although there exist ethical concerns. The formulation of policies guiding its use will ensure the security of information and patient’s confidentiality.
- ItemOpen AccessFactors influencing post-obturation pain in single visit root canal treatment employing rotary endodontics.(APIDPM Sante Tropicale, 2018) Makanjuola, JO; Umesi, DC; Oderinu, OHObjectives To determine the prevalence of post-obturation pain following rotary endodontics in single-visit root canal treatment and to determine factors that may influence post-obturation pain Methodology A prospective, clinical study was conducted at a Nigerian Teaching Hospital. Single-visit root canal treatment was performed on seventy-five teeth. Biomechanical preparation of root canals was done employing ProTaper rotary system in a crown-down technique. Pain was reviewed over a 1-month period employing Universal Pain Assessment Tool5-Faces Scale and patients’ use of analgesics. Factors evaluated for influence on pain were age, gender, tooth type and pre-operative diagnosis. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 20.0, Test for association between prevalence of pain and categorical variables were carried out using Pearson’s chi-square. Level of statistical significance was set as p ≤ 0.05. Results Seventy five subjects were treated. Forty-five (60%) were females and 58.7% belonged to 21-30 years age-group. The central incisors (28%) followed by first molars (23.5%) were the most frequently treated teeth and 56% of the entire teeth presented with apical periodontitis, Table 1. At 1-day review, 38.7% of the teeth had post-obturation pain with central incisors (28%) followed by first molars (23.5%) having the highest prevalence. The prevalence of pain progressively and by the 1-month review, the total pain prevalence reduced to 5.3%. Factors significantly associated with post-obturation pain were being females (p=0.050) and posterior teeth (p=0.037) at both 1-week and 1-month review periods respectively. Conclusion Factors which affect post-obturation pain following single-visit root canal treatment employing ProTaper rotary instrumentation include gender and tooth-type. Post-obturation pain which occurred within 24 hours following treatment steadily reduced over one-month review.

- ItemOpen AccessFixed Bridge Prostheses Management of Epileptic Patients.(Nig Quarterly J Hosp Med., 2012) Umesi, DC; Oderinu, OH; Adegbulugbe, IC; Oremosu, OABackground: Epileptic patients in the course of seizures may suffer damage to or loss of teeth and other oral tissues. Moreover, they are at great risk during their seizures from aspiration of foreign bodies such as removable dental prosthesis or fragments of prosthesis. It is therefore, necessary to provide them a tooth replacement option that would" be safe and not constitute a source of danger in the course of seizures. Case Reports: Two patients are presented in this report that lost teeth as a consequence of trauma sustained during seizures. They both had porcelain-fused-to-metal (ceramo-metal) fixed bridge prostheses fitted to replace the missing teeth. The fixed bridges have been in service for seven years without damage despite the fact that the patients still have seizures at the same frequency as prior to treatment that are often associated with trauma to oral' tissues. Conclusion: Fixed bridge prostheses are a viable tooth replacement option for epileptic patients that do not pose any additional danger of being dislodged, swallowed or aspirated in the course of a seizure.
- ItemOpen AccessFrequency and distribution of teeth treated by single- and multiple-visit root canal treatment by differently skilled operators at a Teaching Hospital in Nigeria.(APIDPM Sante Tropicale, 2016) Umesi, DC; Oremosu, OA; Makanjuola, JO; Nwachukwu, NCSingle visit root canal treatment (RCT) is being advocated around the world. This study profiles RCT in a Nigerian population and compares pattern of single versus multiple visit RCT to tooth type and skill level of the doctors.A retrospective study was carried out on RCT performed in one year by fresh graduates and postgraduate dentists. Records retrieved included patients' sex and age, tooth type, location in the jaw and whether single- or multiple-visit RCT was done.Records of 705 teeth were reviewed, 54.6% belonged to females. Age range was 18-87 years, mean of 31.76 (± 12.31) years. Majority (70.1%) belonged to 20-39 years' age group. Most teeth were located in the maxilla (60.8%) and in posterior regions (73.6%). The most frequently root filled tooth was the mandibular first molar (20.7%) followed by maxillary central incisor (18.4%) then maxillary premolar (12.8%). However, all molars accounted for 47.3%, premolars 26.3% and incisors 25.0%. Canines (1.45%) were least frequently root-filled. Incisors (54.8%) were the teeth most frequently treated in single-visit followed by premolars (28.8%). Most frequently treated by multiple-visit were molars (51.0%). All doctors performed multiple-visit RCT in an approximately equal proportion but a significant percentage of single-visit RCT was carried out by senior doctors (71.2%).The most frequently root filled teeth were mandibular first molars. Teeth most likely to be treated by single-visit RCT were incisors. Appropriate operator skill and experience is important in the decision to perform single-visit RCT. Single-visit RCT is advocated in the developing environment.
- ItemOpen AccessImpact of Tooth Loss on Individuals with Unrestored Partially Edentulous Arch in Southwestern Nigeria - A Preliminary Survey(2016-05) AKINBOBOYE, BOLANLE; SULAIMAN, A O; BAMIGBOYE, S A; AKEREDOLU, P A; DOSUMU, O OThe impact of tooth loss on individual with unrestored partial edentulous space in the southwestern part of Nigeria was assessed. The study was a prospective study of 160 partially edentulous subjects. Trained dentist administered a validated questionnaire. Information sought included, sociodemographics, duration, of tooth loss, causes of tooth loss and reason for replacement. Data analysis was done using descriptive statistics & Chi Square. Mean age of subjects was 45.06+/- 14.22 years. Majority (63.1%) of subjects were traders. Eighty percent of participants were married. More than half (53.1%) of studied population resides in Lagos. Commonest cause of tooth loss was caries (42.5%). Impact on tooth loss showed negative impact on the smile (16.2%), speech (10.6%), mastication (30%), and self-confidence (13.7%). Less than half of the population (43.1%) was indifferent to replacement. Acceptability of appearance following tooth loss was influenced by marital status (p<0.05), location of teeth on the arch (p<0.05). Denture was believed to be a treatment option for tooth loss (p<0.05). There was adverse effect of tooth loss on mastication but little subjective effect on confidence, smiling, and speech. The major reason for not replacing was due to an indifferent attitude (50%) to replacement option and lack of awareness (24.4%). Aesthetics was a strong determinant for replacement.
