Bony defects in dried Bantu mandibles

Area of Science:

• Oral and Maxillofacial Radiology
• Anthropology
• Dental Anatomy

Background:

• Dental anomalies such as apical defects, bifurcation involvements, dehiscences, and fenestrations can affect oral health.
• Accurate detection of these defects is crucial for diagnosis and treatment planning.
• Previous studies have utilized various methods to identify these mandibular bone pathologies.

Purpose of the Study:

• To compare the efficacy of visual examination versus radiographic assessment in identifying apical defects, bifurcation involvements, dehiscences, and fenestrations.
• To determine the frequency of occurrence of these specific defects in a sample of South African Bantu mandibles.
• To establish the concordance between two common diagnostic methods.

Main Methods:

• Examination of 43 dried South African Bantu mandibles.
• Visual inspection of each mandible for the presence of specific defects.
• Radiographic imaging of each mandible to identify the same defects.
• Statistical analysis to compare findings from visual and radiographic methods.

Main Results:

• Frequencies of apical defects, bifurcation involvements, dehiscences, and fenestrations were recorded.
• Statistical evaluation indicated no significant discrepancy between visual and radiographic findings.
• Both methods yielded comparable results in detecting the studied mandibular bone defects.

Conclusions:

• Visual and radiographic examinations are equally effective in identifying apical defects, bifurcation involvements, dehiscences, and fenestrations in mandibles.
• The findings support the reliability of both diagnostic approaches in dental and anthropological studies.
• This concordance can inform diagnostic protocols and research methodologies in the field.
