Abstract
OBJECTIVE: To correlate lateral cephalometric and facial photographic measurements for orthodontic diagnosis in patients with mandibular deficiency.
METHODS: This descriptive cross-sectional study was conducted at Department of Orthodontics, Dental College HITEC-IMS Taxila, Pakistan from Feb 2022 to July 2022. Total 60 patients were selected with the age range of 15-30 years. All selected patients underwent lateral cephalometric radiography in natural head position. These radiographs were manually traced to measure SNB (sella, nasion, B point) and MCL (Mandibular Corpus Length). Facial photographs were taken for Ḿ-Mé (Distance between soft tissue menton and point M’) and TŃ B́ (Angular measurement showing anteroposterior position of mandible) measurements. Using SPSS 20.0, Pearson Correlation ‘r’ assessed the correlation between lateral cephalogram and facial photographs, with a significant P value of ≤ 0.05 considered.
RESULTS: In this study involving 60 patients (26 males, 34 females) with an average age of 21±5.37 years, a statistically significant correlation was observed between facial photographic and lateral cephalometric measurements for orthodontic diagnosis in patients with mandibular deficiency. The Pearson correlation coefficient of SNB and TŃ B́ was 0.788, indicating a high positive correlation. Additionally, the Pearson correlation coefficient of MCL and Ḿ-Mé was 0.571, demonstrating a substantial positive correlation.
CONCLUSION: This study demonstrates a significant correlation between facial photographic and lateral cephalometric measurements in diagnosing mandibular deficiency, suggesting facial photographs' reliability as an alternative to lateral cephalograms in evaluating craniofacial morphology in patients with mandibular deficiency.
