ABSTRACT:

Aim: The study assessed the usefulness of using the newly introduced non-anatomical soft and hard tissue centroid line (S&H centroid) in differentiating between the sagittal and vertical cephalometric interdental relationships in a heterogeneous sample. Methods: This study was held in the Dental Section Allied Hospital, Faisalabad for six-months duration from February 2020 to July 2020. The sample consisted of 87 12 "x 14" side cephalometric radiographs of mixed sagittal individuals; skeletal class I, II and III and vertically; skeletal horizontal and steep planes of the mandible. The mean values of the sagittal and vertical dimensions of the maxilla and the mandible were determined and analyzed. Pearson's correlation coefficient was used to assess reliability. The one-way ANOVA test and the Tukey Post Hoc multiple comparison test were also used with a significant level at P <0.05. The results were also statistically compared to the previously reported homogeneous sample results using an independent t-test at P <0.05. Results: The obtained results indicate high reliability of the intra-researcher, with a correlation coefficient in the range 0.00 - 1.00. A reference line based on the center of gravity enables the evaluation and statistical differentiation of sagittal and vertical interdental relationships in both heterogeneous and homogeneous specimens. Conclusions: In conclusions, the results seem to confirm the usefulness or utility of the line (S&H centroid) in the cephalometric evaluation of the skeleton. Keywords: Cephalometric evaluation of soft and hard tissues, heterogeneous sample.
