 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. The primary aim is to offer detailed guidance for orthodontists holding a Master of Dental Surgery (MDS) degree who seek to pursue further specialization in cleft lip and palate orthodontics. The information presented herein is designed to equip dental professionals with the knowledge necessary to make informed decisions regarding their advanced training and career trajectory. Your specific interest in cleft lip and palate orthodontics underscores a desire for highly specialized, multidisciplinary training that extends beyond a general orthodontic residency. This report will address the unique requirements, opportunities, and challenges inherent in this niche field, providing a structured pathway for aspiring specialists. II. Understanding Fellowships in Medical an...

# Which of the following terms describes an increase in the number of cells? A. Hypertrophy B. Maturation C. Accretion D. Hyperplasia # The concept that growth occurs along an axis from head to tail is known as which growth pattern? A. Anteroposterior B. Proximodistal C. Somatic D. Cephalocaudal # According to Scammons' curves, which tissue system exhibits the most rapid growth during the first few years of life, followed by a plateau? A. Genital system B. General body growth C. Lymphoid system D. Neural system # Which theory of craniofacial growth posits that growth occurs primarily due to adaptive responses of the skeletal tissues to functional demands of surrounding soft tissues and spaces? A. Sutural theory B. Servosystem theory C. Cartilage theory D. Functional Matrix Theory # The primary mechanism for the increase in size of the cranial vault after birth is: A. Su...

# Which of the following cephalometric parameters suggest skeletal class III malocclusion? 1. ANB is less than 0 degree 2. SNA= 84 degrees 3. SNB=82 degrees 4. Wit’s appraisal shows point A before point B 5. FMA is 40 degrees A. 2, 4 and 5 B. 1, 4 and 5 C. 3, 4 and 5 D. 1 and 3 # A patient presents with anterior crowding as a result of large size of teeth in comparison to the base of mandible. This will be classified as: A. Tertiary crowding B. Secondary crowding C. Third degree crowding D. Primary crowding # Which of the following cephalometric angles is primarily used to assess the anteroposterior position of the maxilla relative to the cranial base? A. FMA B. SNB C. ANB D. SNA # A patient with a skeletal Class II malocclusion typically exhibits which of the following characteristics? A. Prognathic mandible B. ANB angle greater than 4° C. Retrognathic maxilla D.

 # Which of the following cephalometric parameters suggest skeletal class III malocclusion? 1. ANB is less than 0 degree 2. SNA= 84 degrees 3. SNB=82 degrees 4. Wit’s appraisal shows point A before point B 5. FMA is 40 degrees (INICET 2025) A. 1, 4 and 5 B. 1 and 3 C. 2, 4 and 5 D. 3, 4 and 5 The correct answer is B. 1 and 3.  Explanation: 1. ANB is less than 0  degrees:  A negative ANB angle indicates that point B (mandible) is anterior to point A (maxilla), which is a classic sign of skeletal Class III malocclusion. 3. SNB= 82  d e g rees : While the average SNB is around 80 degrees, an SNB of 82 degrees indicates a more protrusive mandible relative to the cranial base, which is consistent with a Class III tendency (especially if SNA is normal or reduced). In contrast, SNA= 84  d e g rees (option 2) suggests a protrusive maxilla, which is typically seen in Class II, not Class III. 4. Wit’s appraisal shows point A before point B : This indicates...
