Summary
Supernumerary roots, an anomaly in tooth root morphology, can occur in permanent teeth. This study presents cases of these extra roots in maxillary third molars and mandibular molars and premolars.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Developmental Biology
Background:
- Tooth root morphology typically follows predictable patterns: single roots for anterior teeth, three for maxillary molars, two for mandibular molars, and single roots for most premolars.
- Supernumerary roots are developmental anomalies that deviate from these standard root formations.
- Disturbances in Hertwig's epithelial root sheath during root development are implicated as a cause for supernumerary roots.
Observation:
- This report details cases of supernumerary roots observed in permanent dentition.
- Specific teeth affected include maxillary third molars.
- Mandibular teeth with supernumerary roots in this study were first molars, second molars, and second premolars.
Findings:
- The presence of supernumerary roots in permanent dentition, particularly in molars and premolars, is confirmed.
- The findings highlight variations in root development that can occur beyond typical anatomical descriptions.
- These anomalies can affect various tooth types, including those not commonly associated with extra roots.
Implications:
- Understanding supernumerary roots is crucial for accurate dental diagnosis and treatment planning.
- Knowledge of these anomalies aids in endodontic procedures, surgical extractions, and orthodontic interventions.
- Further research into the etiology and prevalence of supernumerary roots can improve clinical predictability.
