    Awareness of dental implants among dental patients in Nigeria
    (2016-06) Ajayi, Y O; Dosumu, O O; Akeredolu, PA; Akinboboye, B O
    The 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.

    CONTINUING PROFESSIONAL DEVELOPMENT IN IMPLANT DENTISTRY AMONG NIGERIAN DENTISTS
    (2019-06) Ajayi, Y O; Oremosu, O A; Umesi, D C
    The 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

    The 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, GT
    Introduction: 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.

    Evaluation of Aesthetic Outcome of Single Tooth Implant Borne Restoration
    (2018-05) Ajayi, Y O; Akinboboye, B O
    Objective: 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.
