Intra- and Interobserver Reliability of Bone Volume Estimation Using OsiriX Software in Patients with Cleft Lip and Palate Using Cone Beam Computed Tomography.

The objective of the current study was to evaluate intra- and interobserver bone volume measurements and effect of orientation on the reliability of bone volume evaluation in as-acquired vis-à-vis oriented cone beam computed tomography scans using Osirix software and possible correlation between gender, age, and bone volume required. For this, 31 cone beam computed tomography (CBCT) scans of 14 girls and 17 boys (aged 9-13) with unilateral cleft lip and/or palate who met the inclusion criteria were analyzed. Efficacy and reliability of third party software Osirix for bone volume calculation was assessed using as acquired and oriented volumes by three specialists (a radiologist, an orthodontist, and an oral maxillofacial surgeon). The dataset and readings were anonymized to prevent any bias. Two-way mixed model analysis on as-acquired and oriented observations exhibited intra-class coefficient (ICC) values ≥ 0.90. Wilcoxon signed rank test (p = 0.10) and Kruskal-Wallis ANOVA (p = 0.46) indicated that although a clinical difference in volume assessment was seen between as-acquired and oriented observations (inter-observer and intra-observer), it was statistically insignificant. Spearman's bi-variate correlation analysis revealed a significant relation between the type (side) of cleft and bone volume required to fill the defect (p < 0.05). Although there was clinical difference in bone volume measurement by the three observers, it was insignificant statistically. Clefts on the left side in the patients had significantly more bone required than the right side, whereas age and gender had no relation with bone needed to fill the defect. OsiriX software provided good reliability in measurements of bone volume.

Effect of Motives for Food Choice on Oral Health among Primary School Children in Mangalore: An Analytical Survey.

INTRODUCTION: Parents influence children's eating behaviours by making some foods available than others and by acting as models of eating behaviour. Food selected by parents influence general and oral health of their children. AIM: Aim of this study was to assess oral health parameters among primary school children and motives for food choice among their parents in Mangalore. MATERIALS AND METHODS: A total of 759 primary school children aged 5-10 years, and their parents participated in this study. Motives for food choice among parents of children were evaluated by using Food Choice Questionnaire (FCQ). Oral health status of students was assessed by using World Health Organisation (WHO) Basic Oral Health Assessment Form. Data pertaining to dietary habits and demographics was also collected. Descriptive and inferential statistics along with Pearson's correlation and Binary logistic regression were executed for the present study and level of significance was fixed at p<0.05. RESULTS: Caries prevalence was 10.8% and 68.9% in permanent and primary dentitions, respectively. Mean Decayed, Missing And Filled Tooth (DMFT) index scores among study subjects were 0.21±0.72 and 3.08±3.11 for permanent and primary dentitions, respectively. Increase in caries prevalence was significantly associated with decrease in total FCQ scores. FCQ domains 'health', 'natural content' and 'weight control' were significantly correlated with dental caries experience. FCQ also showed significant correlation with socio-economic variables. CONCLUSIONS: Overall, dental caries experience was found to be high. Parental food choice motives positively influenced dietary patterns and caries experience of their children. Caries experience was less in children whose parents reported higher scores on FCQ. Understanding the barriers, identification of risk factors for poor food choices and targeting interventions might formulate ways by which the desired behaviour can be achieved.
