Prevalence of Distal Carious Lesions in Mandibular Second Molars Due to Mesio-Angular Impacted Third Molars.
J Pak Dent Assoc Jan ;30(1):50-5.

OBJECTIVE: This study was conducted to observe the relationship of mesio-angular impacted third molars to the development of distal caries in adjacent second molars. METHODOLOGY: This cross-sectional study was conducted at Nishtar Institute of Dentistry, Multan. Nine hundred and eighty nine periapical, bitewing and Panoramic radiographs were recorded and examined for distally carious second molars and impacted mandibular third molars. SPSS version 23.0 was used for data entry and analysis. RESULTS: Almost 40.8% of the target population reported with distal caries due to third molar impactions. A total of 53.30% of these impactions were of the mesio-angular variety. No distal caries was detected in transverse type of impactions. CONCLUSION: The current study concluded that the prevalence of distal caries in mandibular second molars and the positioning of adjacent impacted mandibular third molars in the dental arch were interlinked. Consequently, extraction of mandibular third molars should be considered to prevent caries and premature loss of second molar teeth.
