Pathologic changes in soft tissues associated with asymptomatic impacted third molars

ObjectiveThe aim of this study was to examine the need for routine removal of asymptomatic impacted third molars under the prophylactic indication, based on the incidence of pathologic changes. The frequency and type of pathologic conditions associated with impacted third molars were also evaluated.Study designOne hundred twenty impacted third molar dental follicles were submitted for histopathologic examination. The association between dental follicles and pathologic changes, age, gender, and angular position were statistically evaluated.ResultsAmong these dental follicles, pathologic conditions were found in 23%. The relation between pathologic changes and angular position was not statistically significant (χ2 = 2.040; P > .05). Pathologic changes were seen mostly in women who were ≥20 years old.ConclusionsCystic changes may be developed in asymptomatic impacted third molars. Asymptomatic impacted third molars should be removed before pathologic changes can occur.
