Factors associated with pericoronitis among subjects with impacted third molars teeth


The removal of impacted third molars is one of the most common procedures inoral surgery. This is because third molars show high incidence of impaction and areoften associated with pain due to pericoronitis.Assess the reasons for extraction and describe the type of tooth angulations andstate of eruption. Determine the association of selected factors with pericoronitis as areason for extraction.A total of 256 patients having symptomatic third molars and referred to the oralsurgery department for consultation, diagnosis and treatment of partially orcompletely impacted third molars in the mandible and maxilla were included in thesample. All these teeth were surgically treated.the most common cause of surgical extraction of third molars was pericoronitis(86.7%). The condition occurs mostly in mandible and in the 25-29 years age group.Horizontal/transverse third molars were more affected by pericoronitis (96.9%)followed by vertical angulations (91.6%). Pericoronitis encountered more frequentlywith complete soft tissue impaction (93.3%).pericoronitis was the most common cause of third molar extraction. Factorsassociated with increased risk of having pericoronitis include: age group 25-29 years,mandible location, Horizontal / transverse angulation type and complete soft tissueimpactions.
