Abstract

Objective: To assess the relationship between radiolucencies associated with the impacted third molars and their patterns of impaction (depth, angle and ramus relationship).

Material and Methods: A cross sectional descriptive study was conducted on 385 Orthopantomograms of patients visiting dental outpatient departments of Sharif Medical and Dental College (SMDC)and Services Institute of Medical Sciences (SIMS) from December 2020 to February 2021. Teeth were analyzed with respect to the angle, depth of impaction and associated radiolucencies in mandibular and maxillary impacted molars. The impacted mandibular molars were also analyzed with respect to ramus relationship. P value ≤ 0.05 was considered significant.

Results: In mandibular molars depth of impaction and presence of caries had significant association (p=0.007). The association between ramus relation and pericoronal radiolucencies (p≤0.001) and external resorption (p=0.040) was significant where pericoronal radiolucencies were greatest in class 2 ramus relationship and external resorption was highest in class 1 ramus relationship. In Maxillary molars the association between depth of impaction and pericoronal radiolucencies (p=0.001) and Periapical radiolucency (p=0.077) was significant where both were seen highest in class C depth of impaction.

Conclusion: In mandibular molars the highest percentage of caries, periapical and pericoronal radiolucencies were seen in class A depth of impaction, Class 2 ramus relationship and mesioangular impactions. External resorption was highest in Class 1 ramus relation. In the Maxilla the highest number of carious teeth, teeth with Periapical and pericoronal radiolucencies were seen in Class C depth of impaction and distoangular angle of impaction.

Key Words: Impacted third molars, Periapical radiolucency, Pericoronal radiolucency, External root resorption, Dental caries, Orthopantomogram (OPG).
