Abstract
Most supernumerary teeth are impacted and asymptomatic. Objective. The aim of this paper is to describe two cases of sequential development of supernumerary teeth in the mandibular premolar region, identified during orthodontic treatment. Reports. The first case describes the radiographic follow-up of a female patient that presented a supernumerary tooth at the age of 9 years and 10 months in the right mandibular premolar region, followed by a further supernumerary tooth in the left mandibular premolar region identified at the age of 11 years and 3 months. In the second case, the radiographic follow-up of a male patient demonstrated 3 supernumerary teeth in the premolar region at the age of 16 years. During orthognathic surgery planning at the age of 20 years and 5 months, a supplemental supernumerary tooth was found in the left mandibular region. Conclusion. Considering the late developing of supernumerary premolars, appropriate follow-up with panoramic radiographs of patients with previous experience of supernumerary teeth is essential for early diagnosis of supplemental premolars to prevent possible complications.
Highlights
Supernumerary teeth can affect the development of occlusion [1, 2], cause root resorption of adjacent teeth, and induce pathological changes such as cysts [3]
Early diagnosis performed with routine radiographic examinations before, during, and after clinical or orthodontic treatment is essential to identify these alterations, which can negatively affect the normal development of occlusion [2, 7]
There are few reports in the literature on sequential supernumerary teeth in the premolar region [8]. Because they tend to occur after the normal tooth development period, they can interfere with orthodontic treatment
Summary
Supernumerary teeth can affect the development of occlusion [1, 2], cause root resorption of adjacent teeth, and induce pathological changes such as cysts [3]. There are few reports in the literature on sequential supernumerary teeth in the premolar region [8]. Because they tend to occur after the normal tooth development period, they can interfere with orthodontic treatment. In previous reviews of the literature on supernumerary teeth, the mandibular premolar region was found to be the most common site of occurrence [5, 11]. The aim of this paper is to report on two cases of sequential development of supernumerary teeth in the mandibular premolar region and discuss the importance of the clinical and radiographic follow-up during orthodontic treatment
