Assessment of the prevalence and characteristics of dens invaginatus in a sample of Turkish Anatolian population

Abstract

Objective: The objective of this study was to assess the prevalence and characteristics of dens invaginatus in anterior teeth and to classify the type of dens invaginatus in a sample of Turkish Anatolian population. Study design: A retrospective study was performed using full-mouth periapical and panoramic radiographs of 1012 patients. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Results: Dens invaginatus was observed in 13 out of 1012 subjects and in only maxillary lateral incisors. There were no periapical lesions in teeth with types I and II, whereas both of the subjects with type III had apical periodontitis at the time of referral. Males and females were almost equally affected by dens invaginatus (P= 0.98). Conclusion: The anomaly was detected in only maxillary lateral incisors with no gender difference and the most commonly observed type of dens invaginatus was type I (81.25%).

Radiographic Study of the Prevalence of Dens Invaginatus in a Sample Set of Turkish Dental Patients

“…Additionally, no dens invaginatus were observed in the mandibular anterior teeth, and maxillary central incisors examined. These findings were consistent with studies of Cakıcı et al[26] Hamasha and Alomari,[15] Kirzioğlu and Ceyhan. [27]…”

“…This figure is considerably lower than the result of the study by Cakıcı et al[26] (0.8%) and by Kirzioğlu and Ceylan[27] (0.8%) among the Turkish population, and the result of the study by Ezoddini et al, (5.8%) among Iranian population, and the study by Poyton and Morgan. [28] These variations in prevalence between different populations may be due to ethnic variations, but may also be influenced by differences in criteria used for interpretation of dens invaginatus and also the specific teeth examined.…”

“…Hamasha and Alomari[15] found a prevalence of 0.65% for individuals and 43.2% for all teeth in Jordanian dental patients. On the basis of person prevalence, the results of Cakici et al[26] and Kirzioğlu and Ceylan[27] were 1.3% and 12%, respectively, in Turkish dental patients.…”

“…[15] However, according to other studies performed in Turkish population, dens invaginatus occurred equally frequent in males and females. [2627]…”

Prevalence and Incidence of Gemination and Fusion in Maxillary Lateral Incisors in Odisha population and Related Case Report

“…Cakici et al, reported that dens in dente was detected in only maxillary lateral incisors, with no gender difference [25]. The permanent maxillary lateral incisor appeared to be the most frequently affected tooth, with the posterior teeth being less likely to be affected [26].…”
