구개치은발육구는 상악 전치에 나타나는 이상 치근 형태의 하나로 구개측 결절부에서 구개치은발육구를 관찰하였으며, 이 구는 치근단을 향하여 여러 깊이와 길이로 연장될 수 있다. 구개치은발육구는 세정되기 어렵고 청결이 불가능하여, 치태와 치석 등이 축적되어 접합상피의 파괴를 일으키고 빠르게 골연하 결손부가 발생할 수 있다. 또한 이차적으로 치수 조직을 이환시켜 근관-치주 병소가 발생할 수 있다. 본 증례 보고는 구개치은발육구로인해 근관 문제까지 야기된 임상증례를 보고하고 근관치료와 함께 여러가지 재료를 이용한 구개치은발육구의 치료결과를 관찰함으로써 이러한 치료방법의 효용성을 평가하고자 하였다.

Purpose: The palatogingival groove is a developmental anomaly of the incisor teeth, which often presents severe localized periodontal disease. The purpose of this study was to evaluate the clinical outcome of palatogingival groove-associated periodontal lesion following flap operation with glass ionomer filling. Methods: Four patients with periodontal lesion associated with the palatogingival groove were chosen for this case study. Clinical indices were taken and radiographic exam was performed at the baseline of the study and four patients were treated by flap operation with GI filling. Post-surgical visits were scheduled at regular intervals to check clinical and radiographic changes. Results: Symptoms and signs of periodontal lesion were almost completely resolved with improvement of periodontal indices. Conclusions: Flap operation with direct glass ionomer restoration is thought to be an acceptable method which can produce favorable results in the treatment of periodontal lesion caused by palatogingival groove on the maxillary lateral incisor.

Palatogingival groove (PGG) is an anomaly in the maxillary anterior teeth, often accompanied by the area of bony destruction adjacent to the teeth with no carious or traumatic history. The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. Related diseases can involve periodontal destruction, combined endodontic-periodontal lesions, or separate endodontic and periodontal lesions. Disease severity and prognosis related to PGG depend on several factors, including location, range, depth, and type of the groove. Several materials have been used and recommended for cases of extensive periodontal destruction from PGG to remove and block the inflammatory source and recover the health of surrounding periodontal tissues. Even in cases of severe periodontal destruction, several studies have reported favorable treatment outcomes with proper management. With new options in diagnosis and treatment, clinicians need a detailed understanding of the characteristics, treatment, and prognosis of PGG to successfully manage the condition.

In recent years, a number of special treatment procedures have been introduced to reestablish new tooth supporting tissues with varying degrees of success including guided tissue regeneration(GTR), bone grafting(BG) and the use of enamel matrix derivative(EMD). EMD is an extract of enamel matrix and contains amelogenins of various molecular weights. Emdogain(EMD) might have some advantages over other methods of regenerating the tissue supporting teeth lost by gum disease, such as less postoperative complications. Emdogain contains proteins(derived from developing pig teeth) believed to regenerate tooth attachment. The decrease in probing depth after EMD treatment is achieved primarily by clinical attachment gain and bone regeneration and only to a minor extent by gingival recession. In conclsion, EMD seems to be safe, was able to regenerate lost periodontal tissues in previously diseased sites based on clinical parameters.
