Teeth fracture among visually impaired and sighted children of 12 and 15 years age groups of Udaipur city, India--a comparative study.

AIM
To compare the prevalence of anterior teeth fracture among sighted and visually impaired children of 12 and 15 years ages in Udaipur city, India.


MATERIALS AND METHODS
A cross sectional study was carried out among 508 children (83 visually impaired and 425 sighted children), which comprised of 55 males and 28 females among visually impaired and 348 females and 77 males among sighted. The survey was carried out using Andreasen's classification for teeth fracture. Data was analyzed using chi-square test, with keeping level of significance at P < 0.05.


RESULTS
It was found that, visually impaired children (32.5%) had significantly higher percentage of teeth fracture than that of sighted children (9.6%) (P = 001). Males had significantly higher percentage of teeth fracture than females in both groups (P = 0.001). It was observed that overjet of more than 3.5 mm had significantly increased risk of sustaining traumatic dental injuries among visually impaired (70.4%) than that of sighted individuals (46.3%) (P = 0.043). However, fracture of teeth was independent of age groups and lip coverage.


CONCLUSION
Prevalence of traumatic dental injuries in a group of individuals with visual impairment was higher than that of sighted. This should alert caregivers to carry out a profound investigation of the events and suggest methods to reduce this type of morbidity.
