  1. Clear Understanding of the fundamental theory concepts of various dental, oral and perioral tissues and structures in the aspects of their anatomy, histology and morphology learned during the didactics.
  2. Practical correlation of oral histology and dental anatomy with their theory knowledge, during our comprehensive lab program.
  3. Instantaneous identification of all the teeth of both primary and secondary human dentitions in the aspects of their morphology and anatomy, the spontaneity of which is gained by our students via the extensive learning and practice of wax tooth carving models; and the knowledge of which is the basic foundation for their coursing through preclinical and clinical postings of upcoming academic years of BDS.
  4. Complete learning and knowledge of identifying the various oral histologic and anatomic structures, thereby equipping our students to be challenge readyin successfully facing and qualifying the University Board Theory & Practical examinations of Dental Anatomy & Oral Histology, that stand as the test of proficiency of our I YEAR BDS students.
