Objectives: The aim of the study was to evaluate the clinical and radiographic success of the Hall technique (HT) and atraumatic restorative treatment (ART) restorations using high-viscosity glass-ionomer cement for the management of occlusal carious lesions in primary molars. Materials and Methods: This randomized clinical study observed 40 children (aged 5-6 years). For each child, one tooth was treated with HT and one with ART. The primary outcome measures for HT restorations were successful, minor, and major failure rates. Clinical evaluations of ART restorations were performed according to the modified United States Public Health Service criteria during 18-month follow-up. McNemar test was used for statistical analysis. Results: Thirty of 40 (75%) participants returned for 18 months of follow-up. In the clinical evaluations of teeth that were treated with HT, the patients did not have complaints of pain or other symptoms, all crowns remained in the oral cavity, the gums were healthy, and the teeth were functional in all evaluations. At the end of the 18-month follow-up, the surface texture and marginal integrity criteria of ART restorations were recorded as 26.7% and 33.3%, respectively. In the radiographic evaluation of 30 patients treated with ART and HT, all restorations were considered successful. Conclusions: The 18-month clinical and radiographic results after treatments applied to single-surface cavities in anxious children showed that both treatment methods were successful.

This clinical report describes designing and fabricating a single-retainer resin-bonded fixed dental prosthesis with a chair-side computer-aided design/computer-aided manufacturing system. The whole procedure, from tooth extraction to final placement of the prosthesis, was completed in one day, and a single clinic visit. No clinical complications were found at the 2-year follow-up after placement of the restoration, and satisfactory functional and esthetic results were achieved.

연구목적: 의도적 재식술은 재근관치료와 치근단 수술이 곤란하거나 실패한 경우 치아를 유지하기 위한 치료 방법이다. 성공적인 의도적 재식술을 위해서 파절 없는 안전한 발치는 필수적인 과정이다. 이를 위해 최근 의도적 재식술을 위한 비외상성 안전 발치법이 소개되었다. 환자 및 방법: 분당서울대학교 병원 치과 보존과에서 의도적 재식술을 시행한 96명의 환자를 대상으로 하였다. 재근관 치료가 실패하였거나 해부학적 접근의 어려움 등으로 치근단 수술이 곤란한 경우나 환자가 거부한 경우를 대상으로 하였다. 술전교정적 정출술을 약 2-3주간 시행하여 치아의 동요도를 증가시키고 동시에 치주인대의 양을 증가시켰다. 이후 Physics Forceps를 이용하여 발치하였으며 결과에 대해 분석하였다. 결과: 96개의 치아는 상,하악 소구치 또는 대구치였다. 완전한 발치 성공은 93% (n = 89)였으며 제한적인 성공(치근의 일부가 부러짐)은 2% (n = 2), 골절제술을 동반하여 발치한 경우가 5% (n = 5)였다. 임상적인 성공률은 95%였으며 전체적인 발치 성공률은 100% 였다. 결론: 비외상성 안전 발치법은 의도적 재식술을 위해 재현성 있고 예측가능한 발치방법으로 볼 수 있다.
