Abstract:

Objective: To conclude the sagittal position of the maxillary 1st permanent molar in class II division I malocclusion patients from lateral cephalogram. Study Design: “Descriptive” (“Cross-sectional study”). Setting: Dental OPD “Department of Orthodontics, University College of Medicine and Dentistry, The University of Lahore”. Study Period: 1st December 2021, till 30th May 2022. Material & Methods: A total of 160 patients ensuring the confidentiality of their diagnostic data, lateral cephalometric was exposed and cephalometric tracing was done by placing mate acetate paper for evaluation of sagittal and vertical dysplasia. For the selected sample, the distance between the distal cusps of the “Maxillary” 1st permanent molar to the PTV line (Pterygoid Vertical) was assessed (PTV-U6). Distance between the PTV lines (Pterygoid Vertical) to the Maxillary Centroid was also calculated. To compare the mean of the variables i.e. PTV-U6 and PTV-Maxillary molar Centroid a student t-test was applied with a P-value = 0.05 as significant. Results: The mean age of patients was 23.69 ± 3.72 years with minimum and maximum ages of 18 and 30 years. There were 73(45.62%) male and 87(54.38%) female cases with a higher female-to-male ratio. The mean PTV-U6 was 20.83 mm ± 2.14 mm with minimum and maximum values as 17 mm and 24.50 mm. The mean PTV-molar centroid value was 28.70 mm ± 0.88 mm with smallest and extreme values of 27.10 mm and 30.10 mm. Conclusion: It was concluded that the sagittal station of maxillary 1st perpetual molar in class II division I malocclusion patients from lateral cephalogram was found, hence by keeping these values of the local population the strategies can be designed as it may be helpful for the patients that many unwanted extractions can be avoided and treatment will be planned as no extraction.
