Bilateral ‘kissing’ molars: A case report

Abstract

Kissing molars are a rare example of impaction wherein the "occlusal surfaces of impacted molars are united by the same follicular space and the roots point in the opposite direction". 1 Most commonly, they involve mandibular third (M3Ms) and second molars; however, other teeth have been known to be involved, for instance a third and fourth supernumerary mandibular molar. 2 Impaction affects as many as 72.7% of third permanent molars in 20-30 years olds. 3 There are many known causes of failure of eruption of teeth such as trauma to primary dentition, mechanical failure of eruption, isolated ankylosis, and lack of space. 4 It is already known that certain medical conditions can predispose to failure of eruption of teeth such as cleidocranial dysostosis. 5 Very few bilateral cases have been published in the literature, so this case adds to this small cohort with the hope to increase awareness and ultimately optimize confidence for onward referral and management. We will also discuss possible treatment planning options for its management.
