Dental Arch Dimensions of Nigerian Children with Hypertrophied Adenoids.

OBJECTIVE: The study objective was to assess the effect of adenoid hypertrophy on the dental arch dimensions of children in Ile-Ife, Nigeria. METHODS: Ninety patients aged 3-12 years attending the Otorhinolaryngology Clinic at Obafemi Awolowo University Teaching Hospital Ile-Ife diagnosed as having hypertrophied adenoids and 90 children from the Child Dental Health Clinic were recruited as adenoid and control subjects respectively. Arch and palatal vault dimensions, including total arch length; inter-canine, inter-premolar, and inter-molar widths; palatal length; and palatal heights measured at three levels and palatal volume were determined for both groups from dental casts. RESULTS: Maxillary arch dimensions were shorter in the adenoid group than the control group; however, only total maxillary arch length was significantly shorter (p=0.049). Mandibular arch dimensions with the exception of inter-molar width were significantly shorter in the adenoid group (p<0.05). Adenoid subjects had significantly increased palatal heights at canine, premolar, and molar levels and reduced palatal volume compared to the control subjects (p<0.05). CONCLUSION: Adenoid subjects demonstrated shorter maxillary and mandibular arch dimensions compared with control subjects, with the differences being more evident in the lower arch. They also exhibited increased palatal heights at all levels and reduced palatal volume compared with control subjects.

Occlusal characteristics of children with hypertrophied adenoids in Nigeria.

BACKGROUND: Nasorespiratory function and its relation to craniofacial growth are of great interest because of the basic biological relationship between form and function, and the accumulating findings of the relationship between mode of breathing, craniofacial growth and orthodontic treatment. OBJECTIVES: The aim of this study was to evaluate the effect of adenoid hypertrophy and sociodemographic variables on the occlusion of children. METHODOLOGY: A total of 180 subjects aged 3-12 years were selected at the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Ninety subjects had hypertrophied adenoids while 90 normal children served as the control group. Orthodontic examinations were carried out and impressions for study models taken. Occlusion was assessed in the anterior-posterior, transverse and vertical planes. RESULTS: Class I relationship was the most prevalent occlusion in both adenoid and control subjects (55.6% and 72.2%, respectively). The occurrence of class II division 1 was significantly higher among adenoid than control subjects (P=0.003). Posterior crossbites occurred significantly more in adenoid subjects in the 9-12 years category. In the vertical plane, the occurrence of deep bite was significantly greater in male than female adenoid subjects. Age had a statistically significant but weak correlation with anterior open bite (r=0.37). Age and BMI also had significant though weak correlations with posterior crossbite in female adenoid subjects (r=0.39 and r=0.36, respectively). Regression analysis also showed that age had a significant effect on the occurrence of anterior open bite, while BMI had a significant effect on the occurrence of class II occlusion in adenoid subjects (P<0.05). CONCLUSION: The presence of hypertrophied adenoids affects the occlusion in the three planes. Age and BMI have significant effects on the occurrence of anterior open bite and class II division 1 malocclusion respectively in adenoid subjects.

Evaluation of self-perceived dental aesthetics and orthodontictreatment need among young adults / Avaliação da autopercepção da estética dental e da necessidade detratamento ortodôntico entre pacientes adultos jovens

Objectives: The aim of the study was to assess the self-perception of dental aesthetics and orthodontic treatment need in a group of young adults. Materials and methods: Perception of dental aesthetics and orthodontic treatment need was assessed among 189 first year university undergraduates using the Oral Aesthetic Subjective Impact Scale (OASIS), a visual analogue scale (VAS), and the Aesthetic component (AC) scale of the Index of Orthodontic treatment Need (IOTN). Data analysis was done using SPSS version 11.0. Descriptive statistics and Chi-square tests were used. One way analysis of variance (ANOVA) was used to identify differences in the mean VAS and OASIS scores according to perceived orthodontic treatment need on the AC scale of IOTN. The relationship between the various scales was examined using correlation tests. Statistical significance was set as p < 0.05. Results: The mean OASIS and VAS scores were 13.61 ± 5.98 and 75.64 ± 18.40 respectively. According to the AC scale of IOTN, 86.8% of participants rated themselves as having no need for treatment, 7.4% borderline need and 5.8% great need for orthodontic treatment. Comparison of mean OASIS and VAS scores according to the AC category showed a trend towards higher mean OASIS scores and lower VAS scores with greater treatment need. ANOVA showed there were significant differences between the AC groups in mean OASIS and VAS scores. Spearman‘s correlation tests between the 3 scales gave low results. Conclusion: There was a low correlation between the OASIS, VAS and AC scale of IOTN in evaluating self-perception of dental aesthetics and orthodontic treatment need. The OASIS and VAS were able to discriminate between participants with different degrees of treatment need.

Objetivos: O objetivo do estudo foi avaliar a autopercepção da estética dentária e necessidade de tratamento ortodôntico em um grupo de adultos jovens. Materiais e métodos: A percepção da estética e a necessidade de tratamento ortodôntico foram avaliadas entre 189 estudantes universitários do primeiro ano, usando a Escala Ortodôntica de Impacto Subjetivo (OASIS), uma escala visual analógica (VAS), e a Escala de Componente Estético (AC) do Índice de Necessidade de Tratamento Ortodôntico (IOTN). A análise dos dados foi feita usando SPSS versão 11.0. Estatística descritiva e Qui-quadrado foram utilizados. Análise de variância (ANOVA) foi utilizada para identificar diferenças entre as médias e pontuações de VAS e OASIS de acordo com a necessidade percebida de tratamento ortodôntico na escala AC de IOTN. A relação entre as várias escalas foi examinada utilizando ensaios de correlação. A significância estatística foi definida como p < 0,05. Resultados: As medias e desvios padrão de OASIS e VAS foram 13,61 ± 5,98 e 75,64 ± 18,40, respectivamente. De acordo com a escala AC de IOTN, 86,8% dos participantes se classificaram como não tendo necessidade de tratamento, 7,4% ficaram na situação limítrofe de necessidade, e 5,8% relataram grande necessidade de tratamento ortodôntico. A comparação entre as medias de OASIS e VAS de acordo com a categoria AC mostrou uma tendência de maior escore para OASIS e mais baixo escore para VAS, com maior necessidade de tratamento. ANOVA mostrou que houve diferenças significativas entre os grupos OASIS e VAS. Testes de correlação de Spearman entre as três escalas apresentaram resultados baixos. Conclusões: Houve uma baixa correlação entre o OASIS, VAS e escala de AC de IOTN na avaliação de autopercepção da estética dentária e necessidade de tratamento ortodôntico. OASIS e VAS foram capazes de discriminar entre os participantes com diferentes graus de necessidade de tratamento.

Psychosocial impact of dental aesthetics among university undergraduates.

OBJECTIVE: The aim of this study was to assess the impact of dental appearance on the psychosocial well-being of young adults in a university community. METHODS: The participants were a sample (165) of first year University undergraduates who completed the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), a condition-specific Oral-Health-Related Quality of Life (OHRQoL) measure and another self-rating instrument, the Perception of Occlusion Scale (POS). Self- and examiner-perceived dental aesthetics were determined using the Aesthetic Component (AC) scale of the Index of Orthodontic Treatment Need (IOTN) and a modification of the Dental Aesthetic Index (DAI). Results were analysed using non-parametric tests (Kruskall Wallis). Statistical significance was set as p<0.05. RESULTS: Participants with varying degrees of self- and examiner-perceived dental aesthetics according to the AC of IOTN and the POS demonstrated statistically significant differences in well-being based on the PIDAQ subscale scores (p<0.05), with the dental self-confidence subscale demonstrating the strongest difference. No significant differences were observed between the modified DAI groups. CONCLUSION: Differences in the quality of life of individuals with varying degrees of dental aesthetics and different levels of treatment need were identified by the PIDAQ. The most significant impact of impaired aesthetics being on dental self-confidence.
