Aim To assess and compare the prevalence of dental trauma in a population of 9‐ to 16‐year‐old children with partially impaired vision and sighted children of Jodhpur city, Rajasthan State in India. Methods In this cross‐sectional study, 121 children with partial impairment of vision were compared with a control group of 356 sighted children for traumatic injuries to the permanent dentition. Children in both the group were aged between 9 and 16 years and residing in a residential school. The survey was carried out using Ellis and Davy's classification of tooth fracture. Data were analyzed using descriptive statistical analysis, and the Chi‐square test was used to compare different variables with P < .05. Results The overall prevalence rates of traumatic dental injury (TDI) in the visually impaired and sighted groups were 24.79% and 9.39%, respectively ( P = .000). Enamel fracture was the most common type of injury, and the maxillary central incisor was most frequently involved in both the groups. Children with overjet >3 mm sustained TDI more frequently in visually impaired children. TDI was higher in children with overjet ≤3 mm in sighted groups ( P = .000). In both the groups children with inadequate lip coverage had higher occurrence of TDI ( P = .000). Conclusion Dental trauma appeared to be more frequent in visually impaired compared to sighted children. The unmet treatment need for children with TDI was very high.
