The impaction of permanent teeth is a pathological situation in which a tooth cannot erupt into its normal functioning position without treatment. The impaction rate is higher for mandibular third molars when compared with other teeth. The cause of mandibular third molar impaction is said to be due to inadequate space between the distal of the second mandibular molar and the anterior border of the ascending ramus of the mandible. Impacted teeth may remain asymptomatic or may be associated with various pathologies such as caries, pericoronitis, and also root resorption of the adjacent tooth. The impaction of third molar is remaining a public health issue in adolescents. Hence, this study aimed to estimate the patterns and prevalence of mandibular third molar impaction.
This is a cross sectional study done with 1580 patients. Participants information regarding age, gender, type of impaction and other related information were collected. OPGs were examined to determine the frequency of third molar impaction, and their levels of eruption and pattern. The degree of impaction was determined by the Winter's classification. SPSS was for statistical analysis.
The overall prevalence of mandibular third molar impaction was 13 per cent. Mesioangular pattern is common in majority of the patients. The mean age of the population is 27 years. Prevalence of impaction was high in female than male.
Mandibular third molar impaction is still a major public health concern among young adolescents.
