Frequency and degree The cervical enamel projection on the buccal surface of first molars were most frequently 0 degree in 47.1%, followed by I degree in 44.2%, III degree in 3.4% and II degree in 2.5% The cervical enamel projection of second molars were most frequently 0 degree in 40%, followed by I degree in 29%, III degree 23% and II degree 8%. They were most frequently found in the maxillary molar teeth. The cervical enamel projection of third molars were most frequently 0 degree in 58%, followed by I degree in 28%, III degree in 10% and II degree in 3%. 2. Resorption of alveolar crest The average distance between the buccal cervical line and the alveolar crest of the maxillary frist molars were 0 degree in 2.87mm, I degree in 3.63mm, II degree in 5.83mm and III degree in 4.27mm. The average distance of the buccal side on the maxillary second molars were 0 degree in 2.36mm, I degree in 2.90mm, II degree in 3.34mm and III dgree in 3.05mm. The average distance of the buccal side on the maxillary third molars were 0 degree 2.00mm, I degree 2.52mm, II degree 2.50mm and III degree 2.83mm., application/pdf}, pages = {22--28}, title = {上顎大臼歯の歯の頸部ほうろう(エナメル)突起}, volume = {11}, year = {1985} }
