Concrescence of teeth represents a rare developmental anomaly of tooth formation in which correctly formed teeth are joined solely via the cementum overlying the roots. In most cases, concrescence occurs in the posterior part of the maxilla and affects molars. A correct diagnosis based on radiological imaging poses difficulties for clinicians. Subsequently, the lack of a correct diagnosis may cause multiple complications such as the formation of an oroantral fistula or palatine tuberosity splintering. The patient, female, age 32, came to a dental surgery clinic for a planned extraction of a partially impacted tooth 17 that had caused a palatal abscess and considerable pain. During the surgical procedure it was discovered that the problem tooth (17) was completely joined with impacted tooth 18. Because of the rare occurrence of both anomalies simultaneously, the authors present a case of concrescent impacted teeth in the lateral segment of the maxilla. The aim of this paper is to make dentists aware of the possibility of encountering this unusual anomaly.

Key words
