Prevalence and characteristics of supernumerary teeth: A survey on 7348 people

Abstract

Objective:The aim of the present study was to determine the prevalence of supernumerary teeth with by evaluating a large group of adult patients in Turkey and to investigate the characteristics of supernumerary teeth with their complications and treatment options.Study Design:This descriptive and retrospective study was carried out in 7348 adult patients aged over 18 years (3212 females and 4136 males). The characteristics of the supernumerary teeth were noted and the diagnosis was made during clinical and radiographic examination with the help of panaromic, periapical, and occlusal radiography. Information on the demographic variables for each patient, including age and gender, were colleceted.Materials and Methods:All supernumerary teeth were classfied under several titles such as location, position, morphology, eruption, clinical complications, and treatment protocols. The data obtained were subjected to statistical analysis. Chi-squared test was used to determine differences in distribution of supernumerary teeth when stratified by gender. The statistical significance was established by confidence interval of 95% (P ≤ 0.05).Results:123 (2.14%) affected patients (69 females and 54 males) were observed with a female:male ratio of 1.28:1 (P < 0.05). One hundred and fifty-six supernumerary teeth were detected in all affected patients.Conclusion:Supernumerary teeth may be observed in adults patients with a similar frequency (2.14%) as in children and young adolescents, and clinicians should take measures and examine all patients carefully even at older ages.

Prevalence of Erupted supernumerary teeth and Associated Oral Complications among a Group of Egyptian Children: A Cross Sectional Study.

“…This male dominance may be explained by the theory which postulates that supernumerary teeth is a sex-linked anomaly associated with X-chromosome. (19,(21)(22)(23) On the other hand, the male/ female ratio in this study disagreed with one study carried out in Turkey by Durmuslar et al, (2015) (24) , where females were more affected than males with a ratio of (1.3:1).…”

Frequency of Teeth Number Anomalies in Costa Rican Children at the Faculty of Dentistry University of Costa Rica

“…Tanto en las hiperdoncias como en las hipodoncias, no presentaron diferencias estadísticamente significativa respecto al género, al igual como se reporta en varios estudios (8,12,31). Sin embargo, una revisión bibliográfica en el 2013 (16) informó que los dientes supernumerarios tuvieron una prevalencia estadísticamente mayor en mujeres que en hombres.…”

“…La prevalencia de supernumerarios varía entre 0,1% y 5,3% en dentición permanente. (9,12,13), mientras que la prevalencia de la agenesias fluctúa entre 0,3% y 11.3% (8,14,15). Dichas prevalencias fueron encontradas al realizar estudios en poblaciones no sindrómicas de individuos que eran atendidos en una facultad de odontología de India, Turquía, Brasil y Japón.…”

Hyperdontia: Exploring the Developmental Abnormality

“…4). Studies report that 57-90% of all detected supernumerary premolars from various studies were mandibular [8,1,38,45,[51][52][53][54] and are the most common supernumerary teeth in the mandible [45,47,53]. Still, the prevalence of supernumerary teeth occurring in the mandibular premolar region is quite low [55].…”
