“…Swan and Hurt,[10] in their study on Indian skulls, noticed a direct association between the contour of the marginal bone and the position of CEP. They also found widening of the periodontal ligament adjacent to the alveolar crest, which allowed the apical portion of the CEP to merge toward the furcation.…”

Background:The objectives of this study were to investigate the incidence of cervical enamel projection (CEP) in molars of Indian dry human skulls and to evaluate its relationship with furcation involvement (FI).Materials and Methods:The material consisted of 944 upper and lower first, second and third permanent molars from 89 Indian dry human skulls. CEPs were investigated from the buccal aspect of the tooth and classified according to a system describeddescribed by Masters and Hoskins. FI was measured horizontally from the buccal aspect into the furcation with a graduated probe to the nearest millimeter. Any measurement ≥2 mm was considered to have positive FI.Results:The results showed that CEPs was found more frequently in the mandibular than in the maxillary molars (2:1). The highest incidence of CEP was found in the mandibular second molar (14.7%) followed by the maxillary second molar (14.6%). The mandibular third molar showed the lowest incidence (5.5%). The association between CEP and FI (87.5%) was statistically significant. This favors the view of the possible role played by such anomalies in the progression of periodontal diseases. CEP in male skulls (77.4%) was significantly more prevalent than in female skulls (20.4%). No significant difference was found between the right and left side of maxillary and mandibular teeth with CEP and FI.Conclusion:The findings suggested the role of CEPs as a local contributing factor in localized chronic periodontitis and FI in molars. Detailed examination as well as early diagnosis of periodontal disease at the region of furcation is clinically very important.

“…[4] The reported prevalence of CEPs has varied significantly among studies: Overall mean values have ranged from 8.6 to 32.6%. [1–8] Hou and Tsai[10] and Swan et al [2] reported Grade I CEPs to be the most common whereas Machtei and Waentein[11] reported Grade II CEP to be the most prevalent (34.8%). Wang and coworkers[12] have reported that 62.5% of teeth with mandibular bifurcation defects exhibit CEPs.…”

Bacterial plaque has been implicated as the primary etiological factor in the initiation and progression of periodontal disease. Anatomic factors such as cervical enamel projections, enamel pearls, and developmental grooves are often associated with advanced, localized periodontal destruction. Enamel projections and pearls are mostly associated with molars. Enamel projections in the furcation areas of molars have no true attachment and are therefore highly susceptible to the creation of a deep periodontal pocket. A close association has been reported in the past between enamel projection and furcation involvement. Here, we present a case report with bilateral cervical-enamel projection and its management by flap operation with odontoplasty, and regenerative procedure by placement of graft in the osseous defect. Decreased pocket depth and a gain in clinical attachment level were observed on follow-up.

“…Correlations between cervical enamel projections and the presence and severity of furcation defects have been reported by several investigators. [19][20][21] Recent electron microscopic studies show that there is even greater complexity to cervical enamel projections than previously thought. 22 Pouchlike openings ( Fig.…”
