Context: This study was conducted in the department of Conservative Dentistry and Endodontics , Govt Dental College

Calicut to evaluate the anatomy of the pulp chamber and the pulp chamber oor in North Kerala population in India and

to see if specic, consistent landmarks or congurations exist and are quantiable.

Aims:

1. To observe the anatomy of the pulp chamber and the pulp chamber oor.

2. To study the relationships of the pulp chamber to the clinical crown and relationship of the orice on the pulp chamber oor.

3. To verify the anatomic laws of pulp chamber anatomy in North Kerala population

Settings and Design: Sixty extracted permanent molars were collected from the Department of Oral & Maxillofacial Surgery, Govt. Dental

College Calicut The teeth were divided into three groups

(i) 20 mandibular molar teeth with three root canals

(ii) 20 mandibular molar teeth with four root canals

(iii) 20 maxillary molar teeth

Methods and Material: All teeth were sectioned at the level of cement enamel junction (CEJ )by using micromotor with straight handpiece and

diamond disk so that the outline of the pulp chamber relative to the CEJ could be observed. Each cut section was irrigated with water, dried and

examined. The teeth were analyzed at National Institute of Technology, Calicut under stereomicroscope and digital photographs were taken to

record observed anatomical relationship.

Statistical analysis used: Observations were statistically analysed using SPSS17 software

Results, Conclusions : The present study shows that laws regarding the location of orices, namely law of orice location 1,2 and 3 were also

found to be valid after the teeth were viewed under stereomicroscope.
