“…According to Mlosek [9], most concrescent teeth occur in the lateral segment of the maxilla and usually affect only two teeth. A similar point of view is expressed by other authors [5,10,11], who claim that the anomaly mostly affects maxillary molars. Those teeth can be erupted or partially or completely impacted.…”

“…This will make possible a more precise planning of the procedure, which in turn minimizes the risk of complications such as palatine tuberosity fracture or development of an oroantral fistula. Additionally, the test results will be proof for the patient, who may think that removing two teeth was unsubstantiated [5,7,19]. Un- fortunately, most of the time, concrescence is first diagnosed during the extraction procedure which is quite often problematic and frustrating both for the patient and the doctor.…”

“…In this anomaly, the roots of two neighboring teeth are fused together by cementum and the crowns develop separately with an indi-vidual root system. The most common cause for this anomaly is the deterioration of the interdental septum between the two germs, which in turn causes their misplacement and crowding [3,5,6]. This defect most commonly affects wisdom teeth and the second molar and is difficult to both diagnose and treat.…”

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 (Dent. Med. Probl. 2016, 53, 2, 291-295).Key words: impacted teeth, concrescent teeth, lateral segment of the maxilla.Słowa kluczowe: zęby zrośnięte, zęby zatrzymane, boczny odcinek szczęki.

Introduction: The development of tooth is a complex process wherein there is series of interactions between the ectoderm and ectomesenchyme. The role of genes in determining the shape and form of a specific tooth has already been defined, the alterations in which can lead to a variety of anomalies in regards to number, size, form, shape, structure, etc. Objective: To review the literature on the developmental anomalies of teeth. Literature review: The developmental anomalies affecting the morphology exists in both deciduous & permanent dentition and shows various forms such as gemination, fusion, concrescence, dilacerations, dens evaginatus, dens invaginatus, enamel pearls, taurodontism or peg laterals. These anomalies have clinical significance concerning esthetics, malocclusion and more importantly predisposing the development of dental caries and periodontal diseases. Conclusion: Knowledge of various diagnostic criteria for identification of these developmental anomalies is significant for early diagnosis and pertinent treatment.
