ABSTRACT
Cemental tear represents a rare form of root surface fracture which makes teeth prone to periodontal breakdown. The diagnosis of cemental tear becomes a challenge as it is usually neglected or misdiagnosed and is also underreported in the literature. Correct diagnosis and early treatment of cemental tear can prevent further periodontal breakdown and may preserve the affected tooth for a longer duration. This case presents the diagnosis, treatment, and an analysis of a right maxillary lateral incisor with an improper endodontic treatment coupled with a cemental tear. Despite surgical removal, the cemental tear led to the development of an endodontic periodontal lesion. This article intends to help recognize early signs and symptoms of cemental tear and establish timely diagnosis. It determines that if the periodontal destruction caused by cemental tears is diagnosed and treated early, it may be possible to prevent further periodontal breakdown and preserve the tooth for a longer period.
ABSTRACT
OBJECTIVES: Palatogingival groove is a developmental anomaly that starts near the cingulum of the tooth and runs down the cementoenamel junction in apical direction, terminating at various depths along the roots. While frequently associated with periodontal pockets and bone loss, pulpal necrosis of these teeth may precipitate a combined endodontic-periodontal lesion. This case presents a case of a lateral incisor anatomically complicated with palatogingival groove. METHODS: Two patients with lesion associated with the palatogingival groove were chosen for this report. Palatogingival grooves were treated with different restoration materials with endodontic treatment. CONCLUSIONS: Maxillary lateral incisor with a palatogingival groove may occur the periodontal disease with pulpal involvement. Elimination of groove may facilitate the periodontal re-attachment and prevent the recurrence.
