- ItemOpen AccessCharacteristics and Study Motivation of Clinical Dental Students in Nigerian Universities(2006) Orenuga, O.O; da Costa, O.OA cross-sectional study of a cohort of 197 clinical dental students in the four accredited dental schools in Nigeria was conducted to determine the sociodemographic characteristics of these dental students and their motives for the choice of dentistry. The results indicate that the number of female dental students in Nigeria is increasing, which reflects a trend well established in virtually all other nations. The vast majority of Nigerian dental students (97 percent) qualified for school based on their performance on the University Matriculation Examination. About one-third, 32.5 percent, indicated that dentistry was their first choice for a career. This choice was greatly influenced by family in 50 percent of this group of students. There were several factors that strongly influenced career choice among students who indicated that dentistry was their first choice: interest, prestige, good employment opportunity abroad, and regular work hours. The need to go into a prestigious and financially lucrative profession similar to medicine were the commonest reasons identified by the group of students for whom dentistry was not the first career choice. The motives for choosing dentistry as a career in this group of students seem to relate to an image of dentistry as a vehicle for the achievement of personal goals. It is recommended that high school students be encouraged to see dentistry first hand. This is because in countries such as Nigeria it is not unusual for a potential dental student to have never visited the dentisT
- ItemOpen AccessDouble teeth in the primary dentition: case report from a Nigerian tertiary hospital.(Nigerian Dental Association, 2011) Olatosi, O.O.; Sote, E.O.The term double tooth is used to describe the developmental dental abnormalities called gemination and fusion. Gemination is an attempted, incomplete division of a single tooth germ during the proliferation stage of odontogenesis, while fusion is the union of two or more independently developing teeth. Although the prevalence of primary double teeth is low, double teeth are of clinical interests because of the associated clinical problems. The clinical problems associated with the condition in the primary dentition are often downplayed for various reasons in spite of their importance. Primary double teeth ought to be carefully investigated so that these clinical problems which may affect the permanent dentition can be effectively managed. Perhaps primary double teeth have not received adequate documentation in our environment because of the low prevalence. This presents four primary double teeth in three patients. One of the cases presented occurred bilaterally, a relatively uncommon phenomena. The associated clinical problems are illustrated in the cases and the management discussed. Although primary double teeth are asymptomatic and in some cases may not interfere with function, they do have associated clinical problems. Early diagnosis and regular clinical and radiographic observations are necessary for effective management and appropriate treatment of the anomaly.
- ItemOpen AccessCauses and pattern of tooth loss in children and adolescents in a Nigerian Tertiary Hospital.(Lagos University Medical Society, 2012-01-01) Olatosi, O.O.; Sote, E.O.Background: Tooth loss diminishes the quality of life and is also related to poorer general health. Premature tooth loss in children can have devastating effects such as compromised aesthetics and function, mesial and distal drifts of adjacent teeth leading to crowding and impaction of the permanent successors and other forms of malocclusion. Objective: To assess the causes and pattern of tooth loss in children and adolescents at the Paedodontic Clinic of the Lagos University Teaching Hospital, Lagos. Methods: This retrospective study was carried out at the Paedodontic Unit of the Lagos University Teaching Hospital, Lagos using clinical records over a period of time from January 2008 to April 2010. Information obtained included age, gender, missing and extracted teeth, and reasons for extraction/tooth loss. Exfoliated primary teeth and congenitally missing teeth were excluded. Data was analysed using Epi info 2007 statistical software. Chi-square test was used to compare proportions of tooth loss among age groups. The level of significance was set at P<0.05 Results: A total of 493 patients aged 1-16 years had lost one or more teeth due to various reasons. There were 244(49.5%) males and 249 (50.5%) females. Majority of the subjects lost their teeth due to caries and its sequelae (64.3%) compared to trauma (10.8%) and orthodontic reasons (23.5%). Seven (1.4%) lost their teeth due to failure of previous treatment such as pulp therapy. Conclusion: Extraction largely due to caries and its sequelae was responsible for most of the tooth loss among the study population. There is the need for intensified oral health education and awareness programmes in the populace with emphasis on prevention of dental caries and early presentation for dental treatment in order to avert premature tooth loss in children and adolescents
- ItemOpen AccessThe prevalence of early childhood caries and its associated risk factors among preschool children referred to a tertiary care institution.(Wolters Kluwer - Medknow, 2015) Olatosi, O.O.; Inem, V.; Sofola, O.O.; Prakash, P.; Sote, E.O.Objective: The aim was to determine the prevalence of early childhood caries (ECC) and its association with infant feeding and oral health‑related behavior among preschool children aged 6–71 months in Lagos. Materials and Methods: This was a descriptive cross‑sectional study in which 302 children aged 6–71 months were selected from four pediatric outpatient clinics in Lagos, Nigeria. A structured questionnaire was used to obtain information regarding oral hygiene practices, dietary habits, breast and bottle feeding, birth weight of child and socioeconomic status of the family, from mothers of the children. The status of dental caries was recorded according to the World Health Organization criteria. Results: The prevalence of ECC among 302 children aged 6–71 months was 21.2% while the mean deft was 0.735. Multivariate logistic regression analysis showed the correlation of ECC with the associated risk factors. ECC was significantly higher in children who were bottle‑fed at night. Method of tooth cleaning other than using fluoridated toothpaste significantly increased the prevalence of ECC. Breastfeeding for duration of 3–6 months showed significantly lesser caries prevalence. Caries significantly increased with age. Conclusion: Early childhood caries is a multifactorial disease in which prolonged duration of breastfeeding, nocturnal bottle feeding, and use of cleaning methods other than fluoridated toothpaste are risk factors for ECC. Oral health promotion programs should be targeted at mothers, pediatricians, nurses, caretakers at day care centers and primary care health workers.
- ItemOpen AccessEffect of mineral trioxide aggregate and formocresol pulpotomy on vital primary teeth: a clinical and radiographic study.(Wolters Kluwer - Medknow, 2015) Olatosi, O.O.; Sote, E.O.; Orenuga, O.O.Background: Pulpotomy is the common therapy for cariously exposed pulps in symptom‑free primary molar teeth. Formocresol (FC) is considered the gold standard dressing agent for pulpotomy, but concerns have been raised over the years about its safety. Other alternative pulpotomy agents have been investigated and suggested. Objective: The objective was to evaluate and compare the clinical and radiographic response of FC and white mineral trioxide aggregate (MTA) as pulpotomy materials on primary molars. Materials and Methods: Fifty primary molars, with deep carious lesion that exposed a vital but asymptomatic pulp, in 37 children aged 4-7 years were treated with conventional pulpotomy procedure. The teeth were divided randomly into two groups. Group I (FC) and group II (MTA). The treated teeth were evaluated clinically and radiographically and were followed‑up for 12 months. Results: At the end of the 12 months follow‑up, the clinical success rates for FC and MTA were 81% and 100%, respectively. There was a statistically significant difference (P = 0.04) between the clinical success rates of FC and MTA. While the radiographic success rates for FC and MTA were 81% and 96%, respectively, there was no statistically significant difference between the radiographic success of MTA and FC. Conclusion: White MTA showed a higher clinical and radiographic success rate when compared to FC as a pulpotomy agent in vital primary molars, and it has a potential to become a replacement for FC in primary molars.
