Self-Perception of Malocclusion Among Nigerian Adolescents Using The Aesthetic Component of The IOTN

Introduction: The practice of orthodontics is very young in South-South Nigeria and there is need for base line data for informed planning. This study was carried out to investigate the self-perception of malocclusion among Nigerian school children aged 12 to 18 years in order to compare their perception with that of an orthodontist and also to determine the influence of gender and age on self-perception. Materials and Methodology: A total of 612 randomly selected schoolchildren comprising 299 (48.9%) males and 313 (51.1%) females with a mean age of 15 + 2.0 years were included in the study, the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was the instrument used to measure the perception of malocclusion by both the school children and the orthodontist. Results: Majority of the students (82.5%) rated their teeth towards the more attractive end of the scale (Grades 1-4). Although self - perception was not found to be related to gender, older children (16-18 years) had an increased level of perception of need. Males and older children were found to be more in need of treatment by the orthodontist. Conclusions: A significant difference was found between the orthodontist’s rating and the students’ ratings of the attractiveness of their occlusions. Age and gender were not found to influence self- perceived orthodontic treatment need. Therefore, for effective orthodontic care, self- perception and not only professional assessment must be taken into consideration when formulating treatment plans to ensure patient satisfaction.

Occlusal Changes from Primary to Mixed Dentitions in Nigerian Children

OBJECTIVE To evaluate longitudinally the occlusal changes between the deciduous and early mixed dentition stages in Nigerian children. MATERIALS AND METHODS The occlusion of 145 3- to 5-year-old children was initially assessed at a popular pre-primary school center in Ibadan, Nigeria in October 2002, using the Foster and Hamilton criteria. The same group of children was followed up for reexamination in October 2006 in the primary school section of the center. Of 61 students who were located and reexamined, 54 (26 male and 28 female) qualified for the study. The molar relationship was assessed using Angle classification, and other occlusal features such as spacing, crowding, overbite, and overjet were also assessed. Descriptive statistics, chi-square test, as well as Pearson correlation coefficient, were applied as appropriate in the analysis of the data. RESULTS Of 32 subjects initially having a flush terminal relationship (Class 1), 22 (68.7%) resulted in a Class I molar relationship, seven (21.9%) had Class II, and three (9.4%) had asymmetric relationships. Mesial step (Class III) was formed initially in 18 and 11 (61.1%) resulted in Class I. A Class III developed in five (27.8%). Significant positive correlations were found for molar relationship, crowding, overbite, and overjet variables (P < .01) between the two periods of assessments, but all were below 0.7 value. CONCLUSIONS Angle Class I molar relationship was favored by initial flush terminal plane and mesial step relationships in the deciduous dentition.

Orthodontic Treatment Need and Complexity among Nigerian Adolescents in Rivers State, Nigeria

Introduction. The assessment of orthodontic treatment need and complexity are necessary for informed planning of orthodontic services. The aim of this cross-sectional study was to assess these parameters using the Index of Complexity, Outcome, and Need (ICON) in a Nigerian adolescent population in a region where orthodontic services are just being established. Methods. Six hundred and twelve randomly selected Nigerian adolescents aged 12 to 18 years were examined using the ICON in their school compounds. Descriptive statistics were employed in the data analysis. Results. Out of a total of 38.1% of the population found to need orthodontic treatment, there were more males and older adolescents. The overall mean ICON score for the population was 39.7 ± 25.3 SD with males having statistically higher mean ICON score. The grades of complexity of the population were 21.6% for very difficult and difficult, 7.5% moderate, and 70.9% mild/easy. Conclusions. Although just over a third of the adolescents were found to have a need for treatment, about a quarter of them were found to have difficult and very difficult complexity grades indicating a need for specialist care. The authors recommend the training of more specialist orthodontists in this region.

Dental aesthetics assessed against orthodontic treatment complexity and need in Nigerian patients with sickle-cell anemia

This study investigates the relationship between dental aesthetics and orthodontic treatment complexity and need in a group of patients with sickle-cell anemia (SCA) in Nigeria. The study sample consisted of 176 individuals - 77 (43.8%) male and 99 (56.3%) female subjects with SCA (aged 10 to 35 years) who were coming for routine medical care to two outpatient clinics. Dental aesthetics were assessed using the Standardized Continuum of Aesthetic Need component of the Index of Orthodontic Treatment Need. Treatment complexity and need were assessed according to the Index of Complexity, Outcome and Need and Dental Aesthetic Index. Both parametric and nonparametric statistics were employed in the data analysis. Significant positive relationships were found between dental aesthetics and orthodontic treatment complexity as well as treatment need according to both indices (p= .000). The correlations of the scores for dental aesthetics and the objectively derived treatment complexity and need were significant (p= .01). About 50% of the subjects had poor dental aesthetics and this correlated with their high orthodontic treatment complexity and need.

Orthodontic treatment complexity and need at the University College Hospital, Ibadan, Nigeria, according to the Index of Complexity, Outcome and Need (ICON): A pilot study

Abstract Although occlusal indices have been useful in research, audit, practice management, and quality assurance in clinical orthodontics, complexity of orthodontic cases had not been easy to assess for a long time in clinical practice. This pilot study aimed at assessing the orthodontic treatment need and complexity in a referral orthodontic centre in Nigeria. A retrospective analysis of 56 pre-treatment study models randomly selected from the orthodontic model collection of the University College Hospital, Ibadan, Nigeria was carried out without any bias for age or gender. The index of Complexity, Outcome and Need (ICON) was used as the outcome measure. Descriptive statistics were employed in the data analysis. Forty-seven (83.9%) of the sample needed treatment. Thirty-four (60.7%) cases were classified as difficult or very difficult. Only 1 (1.8%) and 13(23.2%) belonged to the easy and mild categories, respectively. The overall mean ICON score was 67.4±19.6SD (range 25–104). Considerable proportions of these referred orthodontic cases in Nigeria needed treatment and had treatment complexity comparable to the Caucasians.

Perception of Nigerian athletes of the use of mouth guards to prevent the stresses of sports injury

Objective: The perception of Nigerian athletes of the use of mouth guards to prevent the stresses of sports injuries was examined using psychological, sociological, and physical stress variables. Methods: The descriptive survey research design was used in this study. Participants (n = 333) were selected using the purposive random sampling technique and data were collected using the 4 point Likert type instrument. The coefficient α was used to determine the reliability of the instrument with r = 0.79 for psychological, r = 0.66 for physical, and r = 0.74 for sociological stress. Results: The result reveals that female athletes perceived the use of mouth guards as being more important to prevent the stresses of sports injuries than male athletes, while athletes who had used mouth guards for longer periods also perceived them as being more important to prevent the stresses of sports injuries compared to those who had used them less. The result also revealed a significant difference (p<0.05) among the various sport groups as independent variables on the psychological and physical stress variables. Scheffé post hoc analysis was used to identify the group where significant difference was found. Conclusions: The study concluded that since the impact of injury is perceived to affect the cognitive function of athletes, athletes should be educated on the use of mouth guards in order to reduce the incidence of oral and dental injuries to the barest minimum.

Subjective Opinions of Dental Attractiveness and Orthodontic Treatment Need among Nigerian Adolescents

Introduction: The aim of this study was to evaluate the opinions of a cross-section of 12-18 year old Nigerians about dental aesthetics and to compare the report with their self – perceived need for orthodontic treatment. Methods: A structured questionnaire was administered to 612 12-18 year old Nigerian adolescents who were randomly selected from 6 secondary schools in SouthSouth Nigeria to assess their opinions of dental aesthetics, whilst the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used to assess their selfperceived orthodontic treatment need. Results: Majority (78.1%) of the population expressed satisfaction with the arrangement of their teeth, whilst 82% did not perceive any need for orthodontic treatment (AC Grades 1-4). Their self – perceived orthodontic treatment need was found to increase as their satisfaction with the arrangement of their teeth decreased. Conclusions and recommendations: Although majority of the adolescents realized the importance of dental aesthetics, there was a general low awareness of the presence of their malocclusions. We are recommending that populations in this area be more enlightened on the presence and treatment of malocclusion.
