AI Article Synopsis
- The study examines the occurrence and features of concomitant hypodontia and hyperdontia (CHH) in pediatric patients using panoramic radiographs.
- The research analyzed 41,648 radiographs and identified 145 cases of CHH, showing a prevalence of 0.35%, with a notable gender disparity favoring males.
- Findings highlight that most cases involved missing mandibular teeth and supernumerary teeth typically in the maxillary anterior region, emphasizing the need for early diagnosis and multidisciplinary management.
Article Abstract
Objectives: This study aims to investigate the incidence and clinical characteristics of concomitant hypodontia and hyperdontia (CHH) by performing panoramic radiographs.
Methods: A total of 41 648 panoramic radiographs of pediatric patients who were admitted to the hospitals from January 2019 to May 2021 were reviewed, and 145 CHH patients were included in the study. The presence of CHH was recorded. SPSS 24.0 software was used for statistical analysis.
Results: The prevalence of CHH was 0.35% (145/41 648). Males (102 cases) were obviously more than females (43 cases), and the difference between genders was statistically significant (0.001). The features of congenital permanent tooth loss in this group were predominantly 1 and 2 teeth missing and preferably mandibular lateral incisors and mandibular second premolars missing. The incidence of congenital permanent teeth loss was higher in the mandible than in the maxilla (0.001), but no difference was found in the distribution between left and right (0.84). The features of supernumerary teeth in this group were 1 and 2 teeth, mostly in the maxillary anterior area, mostly conical, mostly vertical inversion and orthotopic growth.
Conclusions: CHH is a rare mixed numeric dental anomaly characterized by congenital missing teeth and supernumerary teeth occurring in the same individual. CHH cases are higher in men than in women. The characteristics of their hypodontia and hyperdontia are similar to those of patients with congenital permanent tooth absence or supernumerary teeth. Early diagnosis of the condition and a multidisciplinary approach for management of such case is recommended.

Background: Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender.

Article Synopsis
- * After analyzing over 10,000 panoramic radiographs, researchers found a CMPC prevalence of 0.69%, with a notable difference between age groups: younger patients (under 10 years) had lower prevalence compared to older patients (ages 10 and above).
- * Most missing canines were found in the upper jaw, with a significant majority of patients having visible primary canines; additional anomalies like other missing teeth and microdontia were also noted among affected individuals.

Amongst the spectrum of dental developmental anomalies, hypodontia is a condition characterized by congenitally missing teeth. Whereas, hyperdontia is a condition that results in the development of an excessive number of teeth. These two conditions are regarded as polar opposites in the progression of dentition development.
