    Abstract: Dental plaque has been implicated as the primary etiology in periodontal disease. Developmental aberrations in tooth morphology such as a Cervical Enamel Projection (CEP) may predispose the affected area to plaque accumulation and consequently cause periodontal breakdown. Cervical enamel projection is the most common anatomic variation in molar teeth. CEPs were most likely found on the buccal surfaces of mandibular molars. Maxillary first molars are particularly noteworthy for anatomical variations of the root canals. The least frequent anomaly appears to be that of the double palatal roots. The aim of this study was to present a case with CEP in palatal side of the first maxillary molar with 2 palatal roots.
