A deep understanding of the relationship between root morphology and periodontal destruction is crucial to successful periodontal care. Most mandibular molars have two roots (one mesial and the other distal) and three canals. The major variant of this tooth type is the presence of an additional third root distally or mesially or a supernumerary lingual root. This article presents a case report of a 14-year-old girl with mandibular first molar having three roots bilaterally which is contributing to the periodontal destruction. There were three walled defect distal to first molar with Grade II furcation involvement distally. Regenerative surgeries were performed and patient was kept under maintenance. The relationship between additional third root and periodontal destruction seldom has been described clearly. This paper has been presented in 34(th) national conference at Dharwad.
深入了解牙根形态与牙周组织破坏之间的关系对于成功的牙周护理至关重要。大多数下颌磨牙有两个牙根（一个近中根和另一个远中根）和三个根管。这种牙型的主要变异是在远中或近中存在额外的第三个牙根或一个额外的舌侧根。本文报告了一例14岁女孩双侧下颌第一磨牙有三个牙根并导致牙周组织破坏的病例。第一磨牙远中有三处骨壁缺损，远中存在Ⅱ度根分叉病变。进行了再生手术，并对患者进行维持治疗。额外的第三个牙根与牙周组织破坏之间的关系很少被清晰描述。本文已在位于达尔瓦德举行的第34届全国会议上发表。
