- The aim of this study was to investigate the correlation of cervical enamel projection (CEP) with furcation involvement (FI) and compare the healing response of molars with or without CEP after surgery. A total of 30 patients contributing 78 maxillary and mandibular first or second molars were included. Plaque Index (PII), Gingival Index (GI), probing pocket depth (PPD) and probing attachment level (PAL) were measured before surgery and 1 and 3 or 6 months postoperatively. During surgery, CEPs were identified and classified with a modified grading system from Masters & Hoskins (24). FI was measured hori-zontally from the buccal aspect into the furcation with a graduated probe to the nearest mm. Any measurement > or = 1 mm was consid-ered as FI. CEPs were found in 33 molars (42%). Grade III CEPs were found in 14 teeth, Grade IIIb in 4 teeth, Grade II in 1 tooth and Grade I in 14 teeth. The results showed no significant correlation of CEP with FI. Nor was CEP significantly affecting the PPD and PAL 3 or 6 months after surgery. However, FI was a significant factor in the fur-ther loss of PAL after surgery. Further studies, involving larger sample size may be necessary in order to give more conclusive results.

Prevalence of cervical enamel projection and its correlation with furcation involvement in eskimos dry skulls

Journal article (peer-reviewed)abstract
- The objectives of this study were to investigate the prevalence of cervi-cal enamel projection (CEP) in molars of Eskimo dry skulls and to study the correlation of CEP with furcation involvement (FI). The ma-terial consisted of 834 upper and lower first and second permanent molars from 133 Eskimo dry skulls. CEPs were investigated from the buccal aspect of the tooth and classified according to a system modi-fied from Masters & Hoskins (12). FI was measured horizontally from the buccal aspect into the furcation with a graduated probe to the nearest mm. Any measurement > or = 2 mm was considered to have positive FI. The result showed a presence of 72% of CEPs among the examined molars. Grade III was found in 53%, Grade II in 9% and Grade I in 11% of the 834 molars. Lower molars had a higher preva-lence of CEPs (78%) than upper molars (67%). With the individual skull used as the unit for analysis, a statistically significant correlation of CEP with FI was found in upper right 2nd molar, upper left 1st mo-lar, lower left 1st and 2nd molars and lower right 1st molar. These re-sults may be of clinical importance since the impact of CEPs to perio-dontal treatment of FIs has been discussed.
