Background/Aim: The increasing worldwide prevalence of traumatic injury to primary teeth has raised concerns among dental practitioners and parents. This is due to the serious impact it has on children's dental as well as overall physical, emotional, and mental health. The aim of this study was to assess the prevalence of different types of traumatic injuries to the anterior teeth in preschool children.
Materials and methods: In this cross-sectional study, 1,800 preschool children, 2–6 years old, were selected from 17 primary schools in Delhi, the national capital region (NCR). The primary maxillary and mandibular anterior teeth of these children were examined by a single examiner, and a questionnaire was filled out by the parent/guardian. Andreasen's classification was used to classify the traumatic injuries. Statistical analysis was done by the Chi-square test, and the p-values ≤0.05 were considered to be statistically significant.
Results: The prevalence of hard tissue injuries was as follows: enamel infraction in 3.9%, enamel fracture in 84.4%, enamel–dentin fracture in 7.79%, and complicated crown fractures in 3.9%. Enamel fracture was the most common type of hard tissue injury, with more prevalence in 5-year-old children (37.6%) and affecting girls (51.9%) more than boys (32.46%). Distribution of children with TDI according to injury to periodontal tissues showed percentage of concussion (24.89%), subluxation (10.92%), extrusive luxation (7.86%), intrusive luxation (15.72%), lateral luxation (24.45%), and avulsion (16.6%) with concussion being the most common. Boys (58.5%) were more affected than girls (41.4%) with concussion, and it was more prevalent in 5-year-old children (51.09%). P-values were insignificant for both hard tissue and periodontal tissue injuries.
Conclusions: Due to the wide variation in the type of injuries and their prevalence, there is a need to spread awareness among parents through educational programs regarding the possible risks and preventive solutions for the same.
