The prevalence and distribution of nonsyndromic hyperdontia in a group of Qatari orthodontic and pediatric patients

Abstract

Objective:There is no data specific to the Qatari population on the prevalence and distribution of hyperdontia. The aim of this study was to investigate the prevalence and distribution of hyperdontia in the permanent teeth among a group of Qatari sample and to compare the present results with findings from other populations.Materials and Methods:Records of 1269 Qatari patients (674 females; mean age 11.8 ± 2.3 and 595 males; mean age 11.4 ± 2.2 years) which included panoramic radiographs were examined to identify hyperdontia in the permanent dentition. Supernumerary teeth were assessed for their location, morphology, number, and whether impacted or not.Results:The prevalence of hyperdontia was 1.6% (females 0.7% and males 0.9%; P < 0169). The most common type of supernumerary teeth was the supplemental (45.5%), followed by the conical (40%). Of the supplemental teeth, the mandibular incisor was the most prevalent (60%), followed by the premolar (20%). No significant difference in the prevalence was found between the maxilla and mandible. More than half of supernumerary teeth identified were impacted (54.5%).Conclusions:The prevalence of hyperdontia in a group of Qatari population was within the normal range of the majority of published studies in the literature. Although not significant, hyperdontia cases were more prevalent in male patients.

A Review of Supernumerary Teeth in the Premolar Region

“…The patient and/or guardian may choose to leave any unerupted supernumerary premolar tooth in situ, especially if it has not caused any iatrogenic effects or is unlikely to interfere with orthodontic treatment. In such a case, it is important to highlight to the patient and/or guardian the potential risks that may occur in the future and the need for periodic radiographic monitoring of the unerupted supernumerary premolar tooth/teeth to detect any iatrogenic damage at an early stage which may occur [56].…”

Prevalence and Patterns of Supernumerary Teeth in a Peruvian Non-Syndromic Population: A Radiographic Study

“…Supernumerary teeth can be diagnosed by clinical evaluation, however when teeth are impacted or not erupted, the use of radiographs become an important tool for diagnosing. Particularly, panoramic radiographs have been widely used for the study of supernumerary teeth and has been recognized as a valid method (Anthonappa et al, 2012(Anthonappa et al, , 2013Alhashimi et al, 2016;Syriac et al, 2017;Tetay-Salgado et al, 2021). Consequently, the use of these radiographs was adopted in this study to evaluate the presence and patterns of distribution of supernumerary teeth in a Peruvian population.…”

“…Supernumerary teeth have been reported to be more common in men than in women, reaching a ratio of 2:1 (Alhashimi et al, 2016;Rao & Chidzonga, 2001).…”

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

“…This difference may be due to the age group of the present study which recruited younger patients compared to other studies as it was reported that supernumerary paramolars and parapremolars develop at a later stage during adulthood. (20,24,27) Regarding the complications; the complications were assessed separately for both of the mesiodentes and supplemental teeth. The most common complication associated with mesiodentes was gingivitis (21.5%), then; three complications (rotation of adjacent teeth, crowding, crowding and midline diastema ) recorded the same prevalence ratio which was (15.8%) , while the third prevalent complication was displacement of adjacent teeth and speech difficulty as both of them recorded the same prevalence percentage which was (10.5%) and finally, both of early shedding of primary incisor and delayed eruption of permanent incisors recorded the least presence percentage which was (5.2%).…”
