Objective: To assess the perception of personal dental appearance and dental aesthetics of a young adult population and to compare this with their normatively assessed orthodontic treatment need., Materials and Methods: This was a cross-sectional study involving 420 undergraduate students aged 18-30years, with no previous history of orthodontic treatment. Objective assessment of dental aesthetics was carried out using the aesthetic component of the Index of Orthodontic Treatment Need (IOTN), while self-administered questionnaires were used to assess perception of personal dental appearance., Results: Over 90% of the students considered healthy and well-arranged teeth to be important to their appearance, however, only 36% of them were satisfied with their dental aesthetics. In addition, three-quarters (75%) of the students reported that they desired to change the appearance of their teeth, majority (56.5%) wanted to change the colour, whilst 31.2% wanted to change the arrangement of their teeth (31.2%). A statistically significant association (P=0.05) was recorded between the level of satisfaction with their dental aesthetics and an objective assessment by an orthodontist., Conclusion: The two most important features in the perception of their personal dental appearance, for this young adult population, were the 'colour' and 'arrangement' of their teeth. There was a statistically significant association between their satisfaction with their dental aesthetics and their normatively assessed orthodontic treatment need, although no correlation was observed between both variables., (Copyright © 2019 CEO.

Introduction: Dental esthetics affects how people are perceived by society and how they perceive themselves, and this may also affect their oral health-related quality of life (OHRQoL). The aim of this study was to compare the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of a young adult population., Methods: This was a cross-sectional descriptive study involving 375 undergraduate university students, aged 18 to 30 years old. Data collection was carried out through oral examinations and self-administered questionnaires. Dental esthetics of the students was assessed using the esthetic component of the Index of Orthodontic Treatment Need. Two OHRQoL instruments were used: the shortened version of the Oral Health Impact Profile and the Psychosocial Impact of Dental Aesthetics Questionnaire., Results: Statistically significant relationships (P <0.05) were recorded between both self-perceived and normatively assessed dental esthetics of the students, respectively, and 3 of the 4 Psychosocial Impact of Dental Aesthetics Questionnaire subscales: dental self-confidence (Kruskall-Wallis, P = 0.000; P = 0.000), psychological impact (P = 0.003, P = 0.047), and esthetic concern (P = 0.006, P = 0.003). The only exception was the social impact subscale, in which a significant relationship was recorded only with self-perceived dental esthetics (P = 0.040). For the shortened version of the Oral Health Impact Profile scale, marked differences were also observed between the impacts recorded for both self-assessments and normative assessments, respectively, particularly for the psychological disability domain (Fisher exact test, P = 0.021, P = 0.000; P = 0.064, P = 0.096)., Conclusions: Differences exist between the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of young adults, particularly in the psychosocial domains. These differences should be considered in orthodontic treatment planning for young adult populations., (Copyright © 2016 American Association of Orthodontists. Published by Elsevier Inc.

Introduction: The aims of this study were to establish the prevalence of dental features that indicate a need for early intervention and to ascertain the prevalence of different methods of early treatment among a population of Nigerian children in mixed dentition., Methods: Occlusal relationships were evaluated in 101 children in mixed dentition between the ages of 6 and 12 years who presented at the Orthodontic Unit, Department of Child Dental Health, Lagos University Teaching Hospital over a 2 years period. The need for different modes of early orthodontic treatment was also recorded., Results: Anterior tooth rotations (61.4%) and increased overjet (44.6%) were the most prevalent occlusal anomalies. Others included deep bite (31.7%), reverse overjet (13.9%), and anterior open bite (14.8%). Severe maxillary spacing and crowding were exhibited in 12.0% and 5.0%, respectively. About a third (35.7%) of the subjects presented with crossbite while lip incompetence was observed in 43.6% of the subjects. About 44% of the subjects also presented with various oral habits with digit (15.8%) and lip sucking (9.9%) being the most prevalent. Subjects were recommended for treatment with 2 by 4 fixed orthodontic appliances (22.3%), habit breakers (20.7%), removable orthodontic appliances (16.5%), and extractions (15.7%)., Conclusions: Increased overjet and anterior tooth rotation were the majority of occlusal anomalies seen, which are not only esthetically displeasing but may also cause an increased susceptibility to trauma to these teeth. Treatment options varied from extractions only to the use of appliance therapy.

Background: Students’ perception of their education is a subject that has received very little attention by those providing dental school education. This is more so in the Nigerian environment, where limited research has been carried out in dental education, particularly with respect to the students’ perspectives on the quality of training received., Objective: Thus, the aim of this study was to determine the perceptions of dental students and recent dental graduates in Nigeria on their level of satisfaction with the quality of academic and clinical training received in their respective dental schools and the challenges faced in receiving this training., Methods: This was a cross-sectional descriptive study carried out amongst 271 dental students and recent dental graduates from eight dental schools in the country. Ethical approval for the study was obtained from the Institutional Review Board of the Lagos University Teaching Hospital (LUTH). Data collection was via self-administered questionnaires. Statistical analysis was carried out using SPSS 17., Results: The final study sample was made up of 239 students, with a mean age of 24.57 (2.21) years. The two dental specialties in which the least level of satisfaction was recorded with regard to the quality of academic training received were Conservative Dentistry and Orthodontics, while for clinical training they were Conservative Dentistry and Oral Biology/Pathology. The three most common factors which were adversely affecting the quality of clinical training received were, poor electricity supply, insufficient dental chairs and quality of training received., Conclusion: Dental students and recent graduates of Nigerian Dental schools are not satisfied with the quality of undergraduate training received in some dental specialties at their respective dental schools.

Introduction: Oral health related quality of life is utilized in health services research to examine trends in oral health and population-based needs assessment., Objective: To assess both the generic and orthodontic specific aspects of the Oral health-related quality of life of a University undergraduate population., Methodology: This was a cross-sectional descriptive study carried out among 420 undergraduate students, aged 18-30years old, attending the University of Lagos, Nigeria. The data collection was carried out through oral interviews and self-administered questionnaires. Two Oral health related quality of life instruments were used (1) A generic scale: the Shortened version of the Oral Health Impact Profile (OHIP-14) and (2) A condition specific scale: the Psychosocial impact of dental aesthetics questionnaire (PIDAQ). Data analysis was carried out using the Statistical Package for Social Sciences (SPSS)., Results: With respect to the Oral Health Impact Profile (OHIP-14) scale, the overall mean score recorded by the students was 10.43+7.85. The physical pain subscale recorded the highest impact with 93.3%, while the least impact was recorded in the handicap subscale, with 29.9%. The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) scales revealed significant gender differences, with the subscales of 'social impact', 'psychological impact' and 'aesthetic concern' recording low mean subscale values., Conclusion: . The mean Oral Health Impact Profile (OHIP-14) score of the students (10.43 + 7.85) in this study reflects that the oral health status of most of the students did not significantly affect their Oral health-related quality of life. However, the physical pain domain was the most severely affected aspect of their Oral health-related quality of life. The Psychosocial Impact of Dental Aesthetics (PIDAQ) scale scores recorded significant gender differences.

Aim: To determine the relevance of routine blood pressure (BP) measurement in patients attending the dental clinic., Materials and Methods: This was a retrospective survey of patients who attended the dental clinic in the Preventive Dentistry Department of a tertiary Hospital in Lagos, Nigeria over an eighteen month period. Data retrieved from the patient's hospital records included age, sex, BP and history of hypertension. Data was analyzed using Epi info 2011 package. p-value <0.05 was considered statistically significant., Results: A total of 1910 patients' records were assessed. Females represented 53.4% (n = 1020) of the study population. The mean age was 37.1 ± 15.0 years (range 18-88 years). The prevalence of hypertension was 39.9% (n = 763). Hypertension was stage 1 in 25.5%, stage 2 in 9.8% and severe in 4.6% of the dental patients. Past medical history of hypertension was obtained for 952 patients (49.8%). Of the 763 patients with high blood pressure, 14.8% had a known history of hypertension, while 42.1% were previously undiagnosed (p < 0.0001). Systolic and diastolic BP increased with increasing age (p < 0.05) and was significantly higher in males than females (p < 0.05)., Conclusion: The high prevalence of hypertension noted among the study population with its potential consequence during dental procedures makes the measurement of blood pressure a valuable assessment in a dental clinic., Clinical Significance: The high prevalence of hypertension particularly the previously undiagnosed cases among the dental patients highlights the relevance of routine blood pressure assessment prior to dental procedures in contemporary dental practice, so as to minimize the potential complications that could occur.

A case report on the orthodontic management of a 10-year-old female patient with Angle's Class II Division I malocclusion, 12 mm overjet, incompetent lips, a deep bite and a lower midline shift to the right using the Twin Block of Clark is presented. Treatment objectives included reduction of the overjet and overbite, obtaining a Class I molar and canine relationship, and improving the patient's profile. After a thorough patient assessment, a two-phase orthodontic treatment plan was chosen with myofunctional therapy using the Twin Block constituting the first phase of treatment. Second phase of treatment was to be carried out using a preadjusted edgewise appliance system. Active treatment with the Twin Block lasted for nine months. Patient's compliance with the appliance was good, and an overjet reduction to 4.5 mm was achieved with an improvement in facial profile after the first phase of treatment. The Twin Block of Clark is a very good treatment alternative in managing selected cases of Angle's Class II Division I malocclusion.

Background: Tooth avulsion has been known to be the most severe of all dental injuries. The immediate action taken at the accident site will determine the prognosis of the tooth. Replantation of an avulsed tooth is the treatment of choice., Aim & Objectives: To assess the knowledge and attitude of primary and secondary (Basic educational) school teachers on the emergency management of avulsed permanent incisors., Setting: Twenty public and private basic educational schools were randomly selected from Lagos State., Subjects & Methods: Descriptive cross-sectional study. A 23 item self administered questionnaire was distributed to teachers to determine their knowledge and attitude on the emergency management of avulsed permanent incisors. Data was analysed using SPSS (Statistical Package for Social Sciences), Version 21.0. The responses obtained were tabulated and expressed as frequency distributions and then computed in percentages. Chi-square was used to test the association between knowledge of the schools teachers regarding the emergency management of avulsed permanent incisors and their socio-demographic variables. Multivariate analysis was used to adjust for confounding variables. The level of significance was set at P ≤0.05., Results: A total of 320 teachers answered the questionnaires. Most of the teachers were female (63.1%). Only (30.9%) had received first aid training which included emergency management of dental trauma. Forty- two percent (134) didn't know that an avulsed permanent tooth could be replanted. Twenty teachers (44.4%) would clean an avulsed tooth with toothbrush and toothpaste. A greater proportion of the respondents 130 (40.6%) would transport an avulsed tooth using a clean white handkerchief. The overall knowledge of the school teachers was poor (84%).There was a statistically significant association between the knowledge of the school teachers and the inclusion of emergency management of dental trauma in the first aid training of the teachers P=0.05. Predictors of teachers' level of knowledge of emergency management of avulsed teeth were receipt of advise on management of traumatic dental injuries (OR= 2.5, CI=1.19-4.28) and type of school (OR=0.93, CI=0.206-0.750)., Conclusion: The school teachers had insufficient knowledge about the emergency management of avulsed permanent teeth. School oral health campaigns with regards to emergency management of avulsed teeth will help improve teachers' knowledge and modify their behaviour.

Asymmetry in the distribution of dental specialists in Nigeria has the potential to negatively affect dental education at all levels. There is a dearth in Nigerian studies on the trends of influencing factors on the choice of dental specialty in Nigeria. Past efforts have not resulted in policy change thus necessitating the current study. One hundred and twelve (51 male, 61 female) Nigerian dental graduates aged 23-55 years with a mean age of 35.21 ± 8.21 years completed self-administered questionnaires to assess the impact of 16 influencing factors on their choice of dental specialty. The graduation period of respondents, which ranged between 0 and 30 years was recorded into three decades and cross-tabulated against 16 influencing factors to assess their relative impact on specialty choice. Diagnostic challenge, predictable work hours and patient type appeared to have maintained a consistent popularity while affluence and income, although less popular influences three decades ago are becoming increasingly relevant while length of programme, prestige and level of crowding exerted less influence on choice of specialty than other factors. The potential influence of incentives such as career counselling and grants for overseas training to encourage enrollment in less popular programmes was assessed based on recommendations from previous studies. However, these measures appeared to be unpopular among Nigerian dental graduates. Diagnostic challenges and predictable work hours remain popular as influencing factors on choice of dental specialty among Nigerian dental graduates. Affluence and income, although previously unpopular are now gaining popularity among Nigerian dental graduates., (© 2013 FDI World Dental Federation.)

Introduction: The soft tissue paradigm is placing greater emphasis on the importance of the soft tissue profile to orthodontic treatment planning. The purpose of this study was to determine the lip dimensions of a Nigerian adult population; compare the male and female values and to compare the values obtained for Nigerians with those reported for other population., Methodology: Lateral cephalometric radiographs of 100 students (44 males and 56 females) of the College of Medicine, University of Lagos, aged 18 to 25 years were taken. Selected subjects were of Nigerian ancestry with normal occlusion and a harmonious facial appearance. The radiographs were manually traced and the upper and lower lip length and thickness of each subject was measured. Statistical analysis was carried out using SPSS, while the male and female values were compared using student's t-tests., Results: Mean values for the lip dimensions were computed for the entire sample. Marked sexual dimorphism was observed with the males having thicker and longer upper and lower lips than the females. The Nigerian sample also had a longer upper lip and a thicker and shorter lower lip than that reported for Caucasians. However, both population had a similar upper lip thickness., Conclusion: Cephalometric norms were developed for the lip dimensions of a Nigerian population. Marked sexual dimorphism was observed in the Nigerian population studied with the males having longer and thicker lips than the females. The lip dimensions of the Nigerian population studied differed from that reported for Caucasians and other racial groups.
