Abstract: (252 Views)
Introduction: Previous research has demonstrated a correlation between certain dental anomalies, including hypodontia, and distinct craniofacial morphological patterns. The aim of the present study was to examine the patterns of dental missing across different craniofacial morphologies.
Materials & Methods: This cross-sectional study enrolled 50 patients aged above 8 years (mean age = 21.66 ± 8.01 years), all presenting with at least one missing tooth due to hypodontia. A matched control group comprising 50 Class I dentition patients with no evidence of hypodontia (mean age = 19.76 ± 7.67 years) was recruited for comparative analysis. Patients were categorized into three distinct groups according to the location of hypodontia within the dental arch, with further classification into three additional categories by jaw location. Diagnostic confirmation of hypodontia and precise localization were established through panoramic radiography, whereas lateral cephalometric analysis served as the primary modality for tracing and measurements.
Results: The lateral maxillary tooth and second mandibular premolars demonstrated the highest prevalence of missing teeth. Furthermore, maxilla length (P=0.04) and SNA (P=0.03) values were both significantly reduced in hypodontia patients relative to controls. No other intergroup differences reached statistical significance in the case and control groups. The findings revealed greater anterior cranial base length, mandibular body length, as well as anterior and posterior facial heights, in male participants compared to their female counterparts. Of particular interest, the angle and position of the mandibular incisors, along with ANB values, tended to be higher in females compared to males (P=0.004).
Conclusion: The present study demonstrated a significant reduction in specific craniofacial parameters, especially maxillary length (ANS-PNS) and SNA angle, in patients with permanent dental agenesis. Important clinical implications of these findings suggest that orthodontists should incorporate these morphological associations into diagnostic evaluations, therapeutic decision-making processes, and comprehensive treatment strategies.
Keywords: Tooth agenesis, Craniofacial morphology, Hypodontia, Cephalometry
