Presentation of Case Dr. Sageer Ahmed (MS Resident): A 60-year-old male came with complaints of a gradual loss of tooth surface structure on the upper left anterior tooth with no complaints of pain and hypersensitivity. He was very much concerned about the appearance of the tooth and develop- ing any pathology and therefore wanted to get his tooth treated. Medical history was not contributory, proper history about foods and diet habits, occupation- al, para-functional, and other abnormal habits were recorded but nothing significant was notified. The only significant was the horizontal brushing technique. On intra-oral examination, tooth surface loss was detected at the cervical area in multiple teeth but it was prominent at the upper left canine tooth. Furthermore, the loss of cervical tooth structure appeared a V- shaped lesion and it was located at the cervical third just above the cement-enamel junction on the labial surface. Moreover, the lesion was yellowish translucent in color and it was hard and smooth when tested by a caries explorer (Figure A). The tooth was non-tender to percussion and palpation. The vitality test also revealed no abnormality. Provisional Diagnosis Cervical tooth loss Differential Diagnosis Chemical Erosion Exogenous and endogenous acids are the cau- ses of cervical erosion of the tooth. 1, 2 The tooth having cervical erosion usually demonstrate a smooth, polished, and saucer-shaped lesion. 3, 4 Exogenous sources include acidic beverages, citrus fruits while the endogenous sources include eating disorders, oesophageal reflux, vomiting, etc. 5, 6 However, well defined outline is absent in erosion, so it was excluded from the diagnosis. Abfraction Abfraction is a defect in the cervical area of teeth, which are wedge-shaped and usually affect a single tooth. 7, 8 The depth of the lesion is greater than its height, and develops due to eccentric forces. 9, 10 However, in the present case, as multiple teeth were affected and the depth of the lesion was less than height, it was also excluded from the diagnosis. Root caries Root caries is a microbial progressive lesion that is soft in consistency and usually develops anywhere on the root surface and is more prominent when there is the loss of connective tissue attachment of the periodontium. 11, 12 It may be irregular, round, or oval-shaped and found when there is the gingival recession, den- tal plaque and in old age. 13, 14 | Case Presentation | No. 2-2021 | Article Info Department of Conservatve Dentstry and Endodontcs, Faculty of Dentstry, Bangabandhu Sheikh Mujib Medical University, Shahbag, Dhaka, Bangladesh For Correspondence: Mozammal Hossain mozammalresearch@gmail.com Received: 7 January 2021 Accepted: 22 January 2021 Available Online: 23 January 2021 ISSN: 2224-7750 (Online) 2074-2908 (Print) DOI: 10.3329/bsmmuj.v14i1.51434 Cite this artcle: Ahmed S, Hossain M, Parvin CA.
