초록

최근 개발된 bulk-fill 복합레진에 대한 연구가 많이 이루어지고 있지만 소아환자 치료에 사용할 수 있는 적절한 재료인지에 대한 연구는 부족한 실정이다. 따라서 본 연구의 목적은 유구치의 2급 와동에서 bulk-fill 복합레진과 전통적 복합레진의 와동 적합성을 비교 평가하는 것이다. 발치 된 80개의 유구치의 근심 또는 원심에 2급 와동을 형성한 후 4개의 군으로 무작위로 나누었다. 대조군은 전통적 복합레진인 Filtek$^{TM}$ Z-350 XT(FZ)으로 수복하고 나머지 3개의 군은 bulk-fill 복합레진인 Filtek$^{TM}$ Bulk Fill Posterior Restorative(FB), Tetric N-Ceram$^{(R)}$ BulkFill(TNC)과 Filtek$^{TM}$ Bulk Fill Flowable Restorative(FBF)으로 수복하였다. 모든 시편을 열순환 시행한 후 50% 질산은($AgNO_3$)용액에 침적시켰다. Micro-CT를 이용하여 전체 질산은의 침투 부피와 치경부의 변연누출 정도를 측정하였고 기포의 개수, 크기, 위치를 평가하였다. 질산은의 침투 부피에서 FB가 FZ보다 유의하게 낮은 값을 보였고(p < 0.05), TNC와 FBF는 FZ와 비슷한 값을 보였다. 치경부 부분의 변연누출 정도는 FBF가 FZ와 FB보다 유의하게 낮은 값을 보였다(p < 0.05). 기포의 개수와 크기는 4개 군 모두 유의한 차이가 없었으나 기포의 위치는 전통적 복합레진에서는 전체 기포의 83.3%가 수복물 내부에 분포하였고, bulk-fill 복합레진에서는 치은축면 선각에 많이 분포하였다. 유구치 2급 와동에서 bulk-fill 복합레진과 전통적 복합레진의 와동에 대한 적합성은 유사한 결과를 보여주었다. 따라서 소아의 치아우식증 수복치료 시 bulk-fill 복합레진이 유용하게 사용될 수 있을 것으로 보인다.

Recently, there have been many studies on bulk-fill resin composites. However, studies on the proper materials for pediatric patients are rare. The aim of this study was to compare the cavity wall adaptation of bulk-fill resin composites with conventional resin composite in class II cavities of primary molars using microcomputed tomography (micro-CT). Standardized class II slot cavities were prepared in 80 exfoliated primary molars and randomly divided into 4 groups. The control group was restored with conventional resin composite, Filtek Z-350 XT (FZ), and the three groups were restored with bulk-fill resin composites, Filtek bulk-fill posterior (FB), Tetric N-Ceram Bulk Fill (TNC), Filtek bulk-fill flowable (FBF). All specimens were thermocycled and then immersed in 50% silver nitrate ($AgNO_3$) solution. Micro-CT was used to measure the penetration volume of the total silver nitrate and the degree of cervical marginal leakage and the number, size, and position of the voids were evaluated. The results revealed that the volume of silver nitrate were significantly different between FB and FZ (p < 0.05). The results also revealed that the penetration length of silver nitrate FBF showed statistically lower than the FZ and FB (p < 0.05). There was no significant difference between the groups in number and size of voids. In conventional resin composite, most of the voids were present inside the restoration (83.3%), but the voids in the bulk-fill resin composites incidence were higher in the gingivoaxial angle. The cavity wall adaptation demonstrated in class II restorations of primary molar by new bulk fill resin composites was similar to conventional incremental technique. Bulk-fill resin composites might be an clinical option for a faster restoration in deciduous teeth.
