Assessment of Maxillary First Molars Rotation in Class II malocclusion cases: A Cross Sectional Study

Introduction: Determination of malocclusion including individual tooth malposition is crucial during diagnosis and treatment planning. Along with anteroposterior mal-relation, there often the rotation upper first molars in Class II cases. Rotated not only occupy more space than normally positioned but also increase challenge for orthodontic treatment. Aims objectives: This study aimed to determine prevalence extent maxillary molar division 1 2 Material Methods: A total 142 pretreatment casts (71 71 2) cases were collected from Department Orthodontics People's Dental College Hospital. All scanned at a 200 dpi resolution teeth touching glass scanner (brother MFC-L2700DW model). Scanned pictures then printed without any change magnification. Measurement was made on those copies casts. To its severity method developed by Ricketts (Line Ricketts) used. Descriptive analysis carried out Microsoft Excel 2013. Result: In cases, 45 (63.4%) had right 47 (66.2%) left rotation. 33 (46.5%) while 34 (47.9%) Similarly, mean rotations 6.24 mm 6.77 respectively 4.82 4.94 respectively. Conclusion: The divisions assessed this study. Mesiopalatal observed commonly both divisions.
