ABSTRACT:

Objective: To explore the curve width in untreated Class II subjects with normal and high mandibular plane points. Study Design: Cross sectional comparative study. Place and Duration of Study: The investigation was led in Jinnah Hospital. Lahore from Oct 2018 to April 2019. Patients and Methods: Pretreatment dental throws and cephalograms of skeletal class II patients with complete arrangement of changeless dentition aside from third molars answering to the OPD of Orthodontic office were chosen. Records of 60 patients (30 high point, 30 typical edges) were haphazardly chosen out of the 240 records examined. Intermolar and intercanine widths were estimated in millimeters utilizing advanced calipers. Mandibular plane edge was estimated from cephalometric tracings utilizing the SN Mandibular plane (GoGn SN) point as utilized in Steiner's investigation. Results: The mean intermolar width for the ordinary edge bunch was 49.18 ± 2.69 mm and 48.56 ± 4.44mm for the high point gathering. The mean intercanine width for the ordinary edge bunch was 34.41 ± 2.33mm and for the high point bunch it was 33.13 ± 2.60mm. Autonomous t test neglected to demonstrate any huge ( p > 0.05 ) contrast in the IMW among ordinary and high edge patients. Anyway a huge ( p < 0.05 ) contrast was seen in the intercanine width of the ordinary and high edge gatherings. Conclusion: In our examination there was no huge distinction of intermolar width while critical contrast of intercanine width was found among ordinary and high point cases. Keywords: Mandibular plane angle, Inter molar width, Inter canine width, skeletal Class II.
