This study confirmed that cervical pulp horns exist in human primary molars as the following results were found: 1. Fifteen cervical pulp horns were observed in the 40 extracted primary molars group (37.5%), 2. Ten cervical pulp horns were observed out of the 26 Indian primary molars group (38.5%), 3. Buccal extension of cervical pulp horns is 0.23 mm in the extracted primary molars group and 0.36 mm in the Indian primary molars group on average, 4. Cervical pulp horns of primary molars tend to be presented bilaterally in the same individual, 5. The percent of occurrence of cervical pulp horns in primary molars (37.6%, 38.5%) was lower than that of the permanent molar (77.1%).
