Prevalence and Characteristics of Supernumerary Teeth in Israeli Orthodontic Patients

Abstract

Background: Supernumerary teeth are one of the most common anomalies in the human dentition, found most frequently in the maxillary anterior region causing impaction or displacement of the adjacent permanent teeth. Aim :The purpose of this retrospective study was to determine the prevalence and characteristics of supernumerary teeth in orthodontically treated patients. Study design: Pre-treatment facial and intraoral photographs, study models, panoramic and periapical radiographs of 3,000 consecutively treated orthodontic patients (mean age 12.2 years) from the Department of Orthodontics Tel Aviv University, were examined to detect supernumerary teeth in both arches. They were recorded according to gender, age, number, location, position and morphology. Results: Thirty-six patients, 22 (61%) males and 14 (39%) females with 50 supernumerary teeth, of which 42 (84%) were found in the maxillary anterior region, and 8 (16%) in the mandible, presenting a prevalence of 1.2%. Conclusions: A prevalence of 1.2% was found in our study. The most common supernumerary tooth is mesiodens located at the maxillary anterior region. The characteristics of supernumeraries were based on their morphology, location and position. The most frequent complications caused were rotations, displacement and arrested eruption of maxillary incisors.

Epidemiological, clinical, radiographic characterization of non‐syndromic supernumerary teeth in Chinese children and adolescents

“…Previous studies usually characterized ST by 2‐dimensional panoramic radiography (Finkelstein et al., 2019; McBeain & Miloro, 2018). However, panoramic radiographic image was unable to definitively and comprehensively present positional and morphological information about ST.…”

Guiding Maxillary Left Central Incisor to Occlusion and Late Formation of a Supernumerary Tooth in the Upper Left Premolar Region

“…One of these dental problems is impaction of the adjacent teeth as it occurred in our case. Early detection and management of extra teeth in the dental arch are a critical factor in minimizing the subsequent dental problems and therefore facilitate orthodontic treatment [ 17 ]. The general dental practitioner should learn when to refer the impacted teeth cases to the orthodontist, as these cases require extra tools for diagnosis and more experience in diagnosis and management.…”

“…The general dental practitioner should learn when to refer the impacted teeth cases to the orthodontist, as these cases require extra tools for diagnosis and more experience in diagnosis and management. One of these tools is CBCT, which provide a precise location for the impacted teeth, determine the accurate position related to adjacent structures, and therefore enable the surgeon for correct surgical removal [ 17 , 18 ].…”

Prevalência de dentes supranumerários em pacientes atendidos em uma clínica-escola de odontologia do norte do Rio Grande do Sul

“…As porcentagens obtidas nesta pesquisa não corroboram os dados de autores que publicaram estudos semelhantes, visto que Patil e Maheshwari (2014) encontraram 105 dentes em 76 indivíduos, resultando em uma prevalência de 1,6%. Finkelstein et al (2019) observaram 50 dentes em 36 indivíduos, obtendo uma prevalência de 1,2%. Khandelwal et al (2018) observaram uma prevalência de 0,63% em sua pesquisa que encontrou 82 dentes extras em 58 indivíduos, resultado semelhante ao encontrado por Bandaru et al ( 2019), que relatou uma prevalência de 0,2%.…”
