 These are some very useful thesis topics that are practically useful and doable by postgraduate students. ## 1. Cephalometric and Radiographic Studies cephalometric analysis in orthodontic treatment planning These studies utilize 2D radiographs (Lateral Cephalograms and OPGs) which are widely available. Cephalometric Norms for a Specific Nepalese Ethnic Group: Establish Steiner's or Tweed's cephalometric norms for a specific population (e.g., Newar, Rai, Gurung) to create a local database. Practical Application: Provides more accurate diagnostic standards for local populations instead of relying solely on Caucasian norms. Soft Tissue Profile Changes after First Premolar Extractions: A retrospective study evaluating changes in the lips and chin position in Class I bimaxillary protrusion cases. Practical Application: Helps in predicting esthetic outcomes and managing patient expectations regarding facial changes.

I. Introduction to Advanced Dental Training This report provides a comprehensive overview of advanced educational pathways within the medical and dental fields, specifically distinguishing between fellowships and clerkships.
