Background: Hypodontia is the absence of one or more teeth in the primary or permanent dentition during development, and radiographic imaging is the most common method of diagnosis. However, in recent years, artificial intelligence-based decision support systems have been employed to make highly accurate diagnoses. The aim of this study was to classify single premolar agenesis, multiple premolar agenesis, and without tooth agenesis using various artificial intelligence approaches.

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.

In cases of agenesis of the mandibular second premolar, a choice can be made from among several treatment options. Besides preserving the second primary molar, it can be decided to close the diastema orthodontically, following extraction of the primary molar. This can be done in several ways: full or partial (hemisection) removal of the primary molar.

Congenital tooth agenesis is a type of craniofacial developmental anomaly with reduced number of teeth, which is caused by disturbances in tooth germ development. If the number of missing teeth is less than six (excluding the third molars), it is termed as hypodontia. The second premolars are most commonly affected.
