Conditions

Decay, Dental, Impacted Third Molar Tooth

Brief summary

Distal surfaces of second molars adjacent to wisdom teeth are always at risk for caries and external root resorption. The incidence of caries is high, especially in partially impacted third molars in mesioangular and horizontal positions. In this study, investigators aimed to examine the caries correlation in the distal second molar with the age, gender, side and DMFT scores of the participants.

Interventions

DIAGNOSTIC_TESTRadiologic examination on orthopantomogram

Caries examination on the distal side of the adjacent second molar in the orthopantomogram of patients with an appointment for the extraction of mesioangular or horizontal partially impacted third molars

DIAGNOSTIC_TESTClinical examination after surgery

İnspectional caries examination on the distal side of the adjacent second molar after surgery of patients with mesioangular or horizontal partially impacted third molars
