Malocclusion and dental caries experience among 8–9-year-old children in a city of South Indian region: A cross-sectional survey

Abstract

BACKGROUND:Although numerous studies have documented malocclusion in various age groups in India, the literature on the prevalence of malocclusion in mixed dentition is scanty. Dental caries is another most common condition affecting the general health. However, its association with malocclusion in mixed dentition is not well known.AIM:The purpose of this study was to establish the prevalence of malocclusion and its association with caries experience in 8–9-year-old children of Davangere city, South Indian region.SETTING AND DESIGN:The study design was a cross-sectional survey.MATERIALS AND METHODS:A total of 800 children from 350 schools (both males and females) were randomly selected for the study. t-test and Chi-square test were used for statistical analysis.RESULTS:The overall prevalence of malocclusion among 8–9-year-old children was 40.9%. The most prevalent malocclusion was crowding (11.5%), followed by excessive overjet (9.4%), deep bite (6.8%), spacing (6.5%), crossbite (4.5%), and open bite (3.2%). Class I molar relationship prevailed in 95.5% of children.CONCLUSION:The prevalence of malocclusion in our study was in accordance with the other studies reported in India, which ranged from 19.6% to 90%. Furthermore, correlation of malocclusion and dental caries in the primary dentition, although nonsignificant, presented children with malocclusion to have a higher caries experience than children without malocclusion.

Prevalence of Malocclusion Among Yemeni Children of Primary Schools

“…Variation in malocclusion can appear between age groups due to age and individual differences, or perhaps a shift from Class II malocclusion to the normal occlusion that occurs from the mesial movement of the first molars in the lower jaw where the second primary molars exfoliated 25 . The prevalence of normal occlusion was found low in the present study (18.9%) comparing with other studies by Alatrach et al, 29 (38.5%), Reddy et al, 22 (48.30%), Al-Zubair and Ghandour, 16 (69.4%), and Disha et al, 24 (59.1%). However, this result almost corresponds with the data in some other studies by Souza et al, 28 (16.7%).…”

“…There was statistic significant difference between the two age groups, which was found higher for age group 7-9 years old 42.0%, compared to the 10-12 years old 29.7%. By comparing with other studies, this result is much higher than that found by Disha et al, 24 study was crowding seen in 30.0% of school children (Table 5). This finding is almost in agreement with that of Almeida et al, 21 (31.59%), Al-Zubair and Ghandour, 16 (31.4%), Al-Zubair and Al-Almulla, 17 (30.4%), and by Yu et al, 26 (28.4%).…”

“…This finding resembles 32 who found that the most common malocclusion was Class I 70.4%. 24 (3.9%). On the other hand, Class III malocclusion was found only in 1.1% (Table 3).…”

“…[23][24][25][26][27][28] . On the other hand, few studies by Gonçalves et al,33 ; Freitas et al,34 ; and by Yu et al,26 emphasized the predominance of Class II, in comparison with relation Class I and Class III.…”

Orthodontic treatment need, self‐esteem, and oral health‐related quality of life among 12‐yr‐old schoolchildren

“…Malocclusion is characterized by the misalignment of teeth and dentofacial discrepancies. It has a moderate to high prevalence among children, regardless of the clinical malocclusion measure or dental index used (5)(6)(7)(8)(9)(10). There is evidence of a negative impact of malocclusion on OHRQoL (11)(12)(13)(14), although other research has not observed this (15,16).…”
