NAME QUALIFICATION DESIGNATION 1. Dr. Prashant kandekar MDS ( Oral Pathology and Microbiology ) Assistant professor (course co-ordinator ) 2. Dr. Syed Mukith MDS ( Oral Pathology
and Microbiology ) Assistant professor 3. Dr. Sreeja Ravindran MDS ( Oral Pathology and Microbiology ) Assistant professor
2. PURPOSE OF THE COURSE:
This course is your first dental lecture and laboratory course presented in the 2nd year BDS curriculum. It introduces you to:
1. The oral cavity.
2. The morphology of individual teeth within the oral cavity. 3. The inter-arch and intra-arch relationships between the teeth.
4. Replicating the anatomy of individual teeth in wax for future application to fixed prosthetics, restorative dentistry.
The lectures will stress nomenclatures ( you need to learn the language of dentistry ) and morphological concepts of the teeth. You need to be able to accurately reproduce the appropriate anatomy in a clinically filled resins, amalgam and gold and to
communicate what is right and wrong with the anatomy of crown to your laboratory technician. These skills are important to your future practice of dentistry.

Upon completion of this course, you should be able to:
1. Recognize the normal anatomic relationships of dental structures for diagnosis and treatment of oral pathology as it involves the dentition.
2. Recognize and define the shape and contour relationship of the normal dentition. 3. Identify, describe and be able to reproduce in drawings and wax, the morphology of
permanent teeth.
4. Correctly name the individual parts of permanent teeth.

12. ISNC STUDENT/S ATTENDANCE POLICY: APP-ISNC-SA-008
The maximum absence of a medical excuse acceptable is not more than 25%. If any student of ISNC cross the limit of absenteeism he/she will not be allowed to enter in the examination.
After five weeks of the beginning of every semester announcement of the percentage of students who exceeded their absence will be posted in the college.
Students who are not allowed to take the examination, will not receive any warning letter, instead an announcement will be posted in the academic affairs in the college. If there is an absence due to a medical condition, students should provide a medical
progress report to the department of academic affairs in a period of not more than five days from the date of the condition. A medical report has to be submitted by the student or their parents within the time frame mentioned. In case of any delay in the submission of medical report, college is not responsible for any excuse after this period.
If the student’s absence from the quiz, practical, mid-term or end-semester examination, a medical excuse is accepted by the dean.
Students have no right to claim and ask for the resit examination if the student’s fee is not completed.
After nine weeks of the beginning of the semester, the students who exceeded above 25% of the absenteeism the end of ninth week a second announcement is made. After 11 weeks, a final announcement of the student who have no right to enter in the
final examination, the students who are crossing the absence above 25% in the semester will be posted in the college.
Attendance regulations for Dental Morphology
This is a year long course with one lectures and one laboratory sessions which makes 2 classes every week and 56 classes in a year.
A student who misses total of 6 classes a semester will be warned first, followed by second warning on missing 9 classes and student will be excluded from the course if he misses 12 classes. In case of sick leave 3 more absence are considered which makes a maximum of 15 absences for exclusion of a student from the course in any given condition.
Note 1: Excluded students has to repeat the course in the next academic year he or she is not entitled for resit examination.
Note 2: No formal letters are given to the students for first and second warning; their names are displayed on the notice board of dentistry program at the end of 5th week, 9th week, 11th week and 13th week of semester. However for exclusion from course a letter is issued on the student name signed by the vice dean of dentistry program.
DENTAL MORPHOLOGY Page 10 Students are expected to to behave in an ethical and professional manner during lectures and laboratory sessions as part of their development towards competent dental professionals.
Students should not disrupt or interrupt the lectures. Students are expected to maintain the security of all the exams and should not give or receive unauthorized aid during exams.
During the laboratory sessions, students should accept criticism in a positive and professional manner. Students should assess their work accurately and in an unbiased maaner, learn to admit weakness and strive to improve.
Students should not take the work of other students as their own during the laboratory sessions or exams.
Students are expected to comply with the dress code and laboratory hours.
Clean up before and after yourself. You will be held responsible for the cleanliness of your own bench. A messy bench after the laboratory session may result in the loss of points for the weeks project.
Students are expected to have all the instruments in each laboratory sessions. Students are expected to maintain clean instruments, in good condition.
