Labial Cervical Vertical Groove: Hidden Route to Periodontal Destruction

A 24-year-old male patient reported to the Department of Periodontology, with a chief complaint of dull, gnawing and intermittent pain while biting in maxillary left central incisors. On clinical examination, localized inflamed, soft & edematous gingival tissue associated with accumulation of plaque and calculus in relation to #11 and#21 was observed. Phase I therapy was instituted and during phase one therapy Labial-cervical-vertical groove (LCVG) was found on #21 which was extending into gingival sulcus. A week after phase one therapy periodontal examination showed a probing pocket depth of 7 mm on distobuccal aspect of #21 with no mobility. On radiographic examination, a round diffuse radiolucency was on distal aspect of #21. This article describes the management of intrabony defect associated with labial-cervical-vertical groove on #21 using bone graft and restoration of groove using glass ionomer cement
