Abstract: Background: Impaction of third molars has been assumed to be a sequel to evolutionary changes in humans over the years. However, depending on the circumstances, these third molars may erupt in proper alignment and remain functional, otherwise they remain impacted at different levels and angulations in the jaws, especially so in mandible because of its density and topography. Partially impacted teeth often present with pericoronitis leading to dilemma in diagnosis and treatment options, as to whether to extract or to carry out operculectomy (and retain the tooth). However, operculectomy would be preferred over extraction owing to its conservative approach. But there has been no data available regarding successful outcome of operculectomy in retaining partially impacted teeth. So, the present pilot study aims to evaluate the outcome of operculectomy in class II position I vertically impacted mandibular molars (most commonly prevalent cases posing diagnostic and treatment dilemma).
Materials and method: 12 patients with 5 of class I (control) and 7 of class II (experimental) impactions were included. They were treated with operculectomy and the degree of occlusal tissue clearance pre-operatively, one week and one month post-operatively was compared using divider and vernier caliper.
Results and observations: Although statistically significant amount of tissue regrowth was observed in experimental group, there was definite relief of symptoms in the post-operative period.
Conclusion: Operculectomy procedure can be a predictable procedure in class II position I vertically impacted mandibular third molars in achieving sufficient occlusal clearance. Thus, the clinicians can conserve these impacted molars by operculectomy.
