Abstract

Calculus is a mineralized bacterial plaque that is formed on natural teeth surfaces where there is constant supply of saliva. Dental calculus is commonly seen over the buccal surfaces of maxillary molars and lingual surfaces of mandibular anterior teeth where the salivary duct opens into the oral cavity. This case report presents an unusual presentation of a large hard calcified mass in the left side of retromolar region associated with partially erupted tooth; hard mass was excised and examined histochemically which suggested the presence of calculus. Elimination of such nidus shall prevent formation of such calculus in such unusual position. This can also be achieved with proper oral hygiene measures.

摘要

牙结石是一种矿化的细菌菌斑，形成于唾液持续供应的天然牙齿表面。牙结石常见于上颌磨牙的颊面和下颌前牙的舌面，此处唾液导管开口于口腔。本病例报告展示了一例不寻常的病例，在磨牙后区左侧有一个与部分萌出牙齿相关的大的硬钙化肿块；切除该硬块并进行组织化学检查，结果提示存在牙结石。消除此类病灶可防止在这种不寻常位置形成此类牙结石。这也可通过适当的口腔卫生措施来实现。
