Various etiologies are implicated as causes of gingival recession and pathological tooth migration, most prevalent among these being the tissue destruction caused by periodontal pathogens. One of the least documented causes is a parafunctional habit, such as digit-sucking or sucking on objects like pencils, pens or toothpicks, all of which can lead to adverse effects on the dentition and the periodontal tissues resulting in midline diastema, alveolar bone loss, gingival recession, mobility, and ultimately tooth loss. This case report describes the periodontal injury caused by an unusual habit of placing a coin between the mandibular anterior teeth. The potential effects of this habit on the dentition and periodontium are discussed; the preventive measures to be taken and the outline for the management of such cases, to ensure periodontal health of the patient are dealt with in this report.
多种病因被认为是牙龈退缩和病理性牙齿移位的原因，其中最常见的是牙周病原体引起的组织破坏。记录最少的病因之一是功能异常习惯，如吮指或吮吸铅笔、钢笔或牙签等物品，所有这些都可能对牙列和牙周组织产生不利影响，导致中线牙缝、牙槽骨丧失、牙龈退缩、牙齿松动，最终导致牙齿脱落。本病例报告描述了一种不寻常的习惯——将硬币放在下颌前牙之间所造成的牙周损伤。讨论了这种习惯对牙列和牙周组织的潜在影响；本报告还探讨了应采取的预防措施以及此类病例的管理要点，以确保患者的牙周健康。
