구치 근관 치료의 임상적 성공은 근관 치료 후 수복에 의해 결정된다. 다양한 방법들이 근관 치료된 구치를 수복하기 위해 제안되고 있다. 소아청소년치과학 영역에서 근관 치료가 필요한 맹출 진행 중인 영구 구치의 전통적인 포스트 코어 및 전장관 수복은 어려움이 많고 과도한 치질 삭제를 유발한다. 치수강을 통한 적절한 유지력이 제공된다면 엔도크라운(Endocrown)은 보존적이고 심미적인 대안이 될 수 있다. 치아 형성은 크라운-코어 일체형의 수복물을 구성하기 위해 치은연과 같은 높이의 버트 조인트(butt-joint) 변연과 치수강 내부 전체의 유지 와동으로 이루어진다. 이 증례 보고는 광범위하게 손상된 부분 맹출된 제1대구치의 엔도크라운을 통한 심미적이고 보존적인 수복의 결과를 기술하고 있다.

Abstract ▼ AI-Helper

Post-endodontic restorations are both important and challenging for clinical success in endodontically treated posterior teeth. Several options have been proposed to restore endodontically treated molars. In pediatric dentistry, restoration using conventional single crowns, especially for partially erupted molars with insufficient retentive tooth structure, has proven to be difficult. However, the endocrown presents a conservative and esthetic restorative alternative to conventional crowns with post-and-core, as it acquires additional retention within the pulp chamber. The tooth preparation consists of a circular, equigingival, butt-joint margin and a central retention cavity in the pulp chamber that helps to construct both the crown and core as a single unit. This case report describes the esthetic and conservative endocrown restorations of erupting permanent first molars with extensive coronal destruction.

문제 정의

The purpose of this case report is to discuss the use of the endocrown in pediatric dentistry to replace single crowns with intraradicular retention or PMCs. Here, we present two clinical case reports on endocrown restorations performed in partially erupted mandibular and maxillary first molars with extensive coronal destruction due to dental caries.

제안 방법

A clinical examination showed a pulp polyp resulting from extensive carious exposure. Based on the clinical and radiographic findings, the maxillary left first molar was diagnosed with chronic hyperplastic pulpitis (Fig. 6), and the root canal treatment was performed. Considering the amount of remaining tooth structure and the partially erupting stage of the tooth, the endocrown was selected as the post-endodontic restoration along with an additional request for esthetics by the patient.
6), and the root canal treatment was performed. Considering the amount of remaining tooth structure and the partially erupting stage of the tooth, the endocrown was selected as the post-endodontic restoration along with an additional request for esthetics by the patient.
In this clinical case report, it was decided that the endocrown restoration would be appropriate for partially erupting molars with extensive loss of coronal structure after endodontic treatment. The restorations were fabricated with Artglass^®, and the prognosis was good during the 2-year follow-up.
Modern clinical concepts to restore endodontically treated posterior teeth are based on the principles of the minimal invasive dentistry[1]. Preservation of the remaining tooth structure is critical to build the foundation for a post-endodontic restoration for strengthening the restored tooth. Other important considerations in the restoration of endodontically treated teeth are the interocclusal space and the height of the remaining coronal tissue, which influences the strength and retention of the final restoration[4,5].
The restorations were fabricated with Artglass®, and the prognosis was good during the 2-year follow-up.

A 9-year-old female patient visited the department of pediatric dentistry at Chonnam National University Dental Hospital with a chief complaint of pain in the left maxillary first molar. A clinical examination showed a pulp polyp resulting from extensive carious exposure.
A 9-year-old male patient, with delayed development and mental retardation, visited the clinic for the disabled in Chonnam National University Dental Hospital with a chief complaint of multiple caries. The intraoral examination revealed that multiple teeth were affected by caries, especially, the left mandibular first molar with extensively destructed coronal structure (Fig.
