牙科外傷除了常造成牙齒的傷害、周圍軟硬組織喪失,有時還可能導致牙齦色素沈積。本病例報告提出一位43歲罹患慢性牙周炎的女性,因上顎前牙區反覆的撞擊傷害,造成牙齦黑斑。病患給予切除牙齦黑斑、拔除預後不佳的右上正中門牙,並進行軟組織牙(山脊)增進術。在全口牙周治療包括左上犬齒施行牙根覆蓋手術,臼齒區域則給予自體骨移植手術及引導組織再生手術治療骨缺損。術後一年的追蹤,上顎前牙區軟組織外觀及顏色和諧,牙齦色素沈積沒有復發,全口探測深度降爲3毫米以下,且在骨移植手術區域有顯著獲得臨床附連。經由完整的牙周病治療,病患恢復整體牙周健康及美觀獲得顯著改善。
Dental trauma usually causes tooth injury, loss of surrounding soft and hard tissues, and sometimes results in gingival pigmentation. This paper reported the management of a 43-year-old female who presented with chronic periodontitis, combined with melanin pigmentation over maxillary anterior area due to repeated traumatic injuries. The treatment procedures for this patient included excision of pigmented gingiva and soft tissue ridge augmentation following extraction of poor prognostic tooth of maxillary right central incisor. In addition, conventional periodontal surgeries consisted of root coverage procedure for the denuded root of maxillary left canine, autogenous osseous grafting and guided tissue regeneration for the molar teeth. One-year postoperative examination revealed harmonious soft tissue contour with no evidence of gingival repigmentation over maxillary anterior area. The full mouth probing depth was less than 3 mm and significant gain of clinical attachment level over osseous grafting sites was found. The overall periodontal health was improved and a favorable esthetic outcome was achieved.
