  • A variety of therapeutic modalities can be used for the endodontic treatment of a traumatized tooth with internal root resorption (IRR). The authors present a case report of the successful restoration of a traumatized upper central incisor that was weakened due to severe IRR and subsequent periapical lesion formation. A 20-year-old female patient was referred to our clinic with severe internal resorption and subsequent periapical pathosis destroying the buccal bone wall. Root canal treatment had been initiated previously at another dental practice, but at that time, the patient's condition could not be managed even with several treatments. After cone-beam computed tomography imaging and proper chemomechanical cleaning, the tooth was managed with a mineral trioxide aggregate plug followed by root canal filling using short fiber-reinforced composite, known as the Bioblock technique. This report is the first documentation of the use of the Bioblock technique in the restoration of a traumatized tooth. The Bioblock technique appears to be ideal for restoring wide irregular root canals, as in cases of severe internal resorption, because it can uniquely fill out the hollow irregularities of the canal. However, further long-term clinical investigations are required to provide additional information about this new technique.

  • Objectives: This study compared the retention of BioAggregate (BA; Innovative BioCeramix) and mineral trioxide aggregate (MTA; Angelus) as coronal plugs after applying different intracanal medications (ICMs) used in regenerative endodontic. Materials and Methods: One-hundred human maxillary central incisors were used. The canals were enlarged to a diameter of 1.7 mm. Specimens were divided into 5 groups (n = 20) according to the ICM used: calcium hydroxide (CH), 2% chlorhexidine (CHX), triple-antibiotic paste (TAP), double-antibiotic paste (DAP), and no ICM (control; CON). After 3 weeks of application, ICMs were removed and BA or MTA were placed as the plug material (n = 10). The push-out bond strength and the mode of failure were assessed. The data were analyzed using 2-way analysis of variance, the Tukey's test, and the ${\chi}^2$ test; p values < 0.05 indicated statistical significance. Results: The type of ICM and the type of plug material significantly affected bond strength (p < 0.01). Regardless of the type of ICM, BA showed a lower bond strength than MTA (p < 0.05). For MTA, CH showed a higher bond strength than CON, TAP and DAP; CHX showed a higher bond strength than DAP (p < 0.01). For BA, CH showed a higher bond strength than DAP (p < 0.05). The mode of failure was predominantly cohesive for BA (p < 0.05). Conclusions: MTA may show better retention than BA. The mode of bond failure with BA can be predominantly cohesive. BA retention may be less affected by ICM type than MTA retention.

  • Mineral trioxide aggregate (MTA)는 치근 천공을 수복하기 위한 생체적합성이 우수한 재료로 소개되었으며 현재 근관 치료의 다양한 분야에서 사용되고 있다. MTA는 전통적인 수복재료와는 달리 수분이 있는 환경에서 경화되는 특징이 있다. 임상에서 흔치는 않지만 경화되지 않은 MTA가 관찰되는 경우가 있으나 이의 원인은 불명확하며 관련된 연구도 많지 않다. 본 증례는 정 방향 MTA 충전 6년 후 MTA가 소실(wash-out)된 환자에 대한 증례로서 그 원인에 대해 고찰해보고자 한다.

  • 이 연구의 목적은 서로 다른 두 개의 근관 크기(#70, #120)를 가진 레진 모형에 MTA (minoral trioxide aggregate)를 서로 다른 두 가지 방법 (수기구 충전(HC), 초음파 보조 수기구 충전(UAHC))으로 정방위 충전하고 MTA apical plug의 미세 누출을 평가하는 것이다. 직선형 근관 형태를 가지며, #70과 #120의 치근단 크기를 갖는 레진 모형을 각각 30개씩 준비하였다. 이 시편들을 MTA의 적용 방법에 따라 각 군을 2개의 아군으로 다음과 같이 분류하였다 (n=15); C70: HC + 치근단 크기 #70, C120: HC + 치근단 크기 #120, U70: UAHC + 치근단 크기 #70, U120: UAHC + 치근단 크기 #120. MTA 충전을 완료한 후에, 24시간 동안 실온에서 100% 습도를 유지하여 경화시켰다. 근관의 상부는 열연화 충전 시스템(Obtura II)을 이용하여 충전하였다. 48시간 동안 100% 습도를 유지하여 실온에서 0.2% rhodamine B 용액을 이용해 미세누출 실험을 하였다. 이 연구결과 #70의 치근단 크기를 갖는 그룹 사이에서 UAHC가 HC에 비해 미세누출이 적은 것으로 나타났다(p<0.05). 이 연구 조건하에서는 초음파 진동을 동반한 정방위 MTA apical plug 형성 방법이, 특히 좁은 근관에서 더 효율적인 것으로 사료된다.

  • Objectives: This study evaluated the effects of Biodentine (BD), Bio-C Repair (BCR), and mineral trioxide aggregate (MTA) plug on the fracture resistance of simulated immature teeth with replacement root resorption (RRR) and in vitro-induced osteoclastogenesis. Materials and Methods: Sixty bovine incisors simulating immature teeth and RRR were divided into 5 groups: BD and BCR groups, with samples completely filled with the respective materials; MTA group, which utilized a 3-mm apical MTA plug; RRR group, which received no root canal filling; and normal periodontal ligament (PL) group, which had no RRR and no root canal filling. All the teeth underwent cycling loading, and compression strength testing was performed using a universal testing machine. RAW 264.7 macrophages were treated with 1:16 extracts of BD, BCR, and MTA containing receptor activator of nuclear factor-kappa B ligand (RANKL) for 5 days. RANKL-induced osteoclast differentiation was assessed by staining with tartrate-resistant acid phosphatase. The fracture load and osteoclast number were analyzed using 1-way ANOVA and Tukey's test (α = 0.05). Results: No significant difference in fracture resistance was observed among the groups (p > 0.05). All materials similarly inhibited osteoclastogenesis (p > 0.05), except for BCR, which led to a lower percentage of osteoclasts than did MTA (p < 0.0001). Conclusions: The treatment options for non-vital immature teeth with RRR did not strengthen the teeth and promoted a similar resistance to fractures in all cases. BD, MTA, and BCR showed inhibitory effects on osteoclast differentiation, with BCR yielding improved results compared to the other materials.

  • 재생적 근관치료는 치수 괴사를 보이는 미성숙 영구치 치료에 있어서 괴사된 치수를 치유하고 계속되는 치근의 발달을 유도할 수 있다. 그러나 여기에는 몇 가지 단점과 불리한 결과들이 있다. 이 중 재생적 근관치료에 가장 큰 임상적 부작용은 minocycline과 MTA에 의한 변색이다. 본 증례에서는 재생적 근관치료 후에 나타나는 치관 변색을 방지하기 위해 minocycline을 clindamycin으로 대체한 triple antibiotics와 칼슘 지르코늄 알루민산염 시멘트인 Retro MTA를 사용하였다. 치수 괴사된 미성숙 영구치에서 근관 와동 형성 및 근관 세척 후 수정된 triple antibiotics를 적용하고, 혈병 또는 콜라겐 스펀지를 스캐폴드(scaffold)로 하여 Retro MTA로 근관을 폐쇄하였다. 정기적인 검진 결과 미성숙 영구치의 치근 성장 및 정상적인 치아 주위 조직들이 관찰되었으며, 치관 변색 없이 모두 양호한 치유 결과를 얻었다.
