Background: Mandibular third molar is the most common tooth to be impacted associated with the complication of distal caries on the mandibular 2nd molar. This can be prevented if the impacted tooth is diagnosed early and provided appropriate management. The aim of this study is to assess the incidence of distal caries in second molar due to impacted third molar in PIDC. The objectives of the study are to evaluate the incidence of distal caries in mandibular second molar by impacted third molar teeth together with the gender variation, angulation and age group in the incidence of distal caries of second molar.
Aims and Objectives: The present study is aimed to assess incidence of distal caries in second molar due to impacted third molar in Penang International Dental College (PIDC), Penang, Malaysia. The objectives of the study were to evaluate the incidence of distal caries in mandibular second molar by impacted third molar teeth, to assess the gender variation in the incidence of distal caries of second molar, to assess the association between distal caries and different types of angulations of third molar impaction and to assess the most prevalent age group having distal caries in mandibular second molar. Thus, the researchers are able to reduce the risk of distal caries in second molar by identifying its relation with the impacted third molar.
Methodology: This is an evidence based study conducted on 45 patients, who have impacted 3rd molar with the age of 18 and above that visit the college PIDC. The gender variation, ethnicity, including the age of the patient are recorded. The periapical radiograph or pre-op OPG are taken to determine the impaction and distal caries.
Results: According to this study results, 57.78% cases show caries on the distal aspect of the mandibular 2nd molar due to impacted 3rd molar. The incidence of distal caries with horizontal impaction was 46.15%. A majority of horizontal impaction cases were found as per the Pell and Gregory classification. Males show higher incidence compared to females (57.69%) with the age group of 23 - 27 and 28 - 33 (30.77%).
Conclusion: In conclusion, more than half of the patients in PIDC have distal caries in the second molar due to the impacted 3rd molar, hence prophylactic removal should be considered, especially in horizontal impaction. Besides, males and patients with the age of 23 and above should pay more attention to their impacted 3rd molar as they have higher risk of developing distal caries in the second molar.
