Abstract

INTRODUCTION

There are several cosmetic, restorative materials to restore non-carious Cervical Lesions (NCCLs). The aim of this study was to specify and compare the shear bond strength of Giomer and resin-modified glass ionomer in Class V lesions so that whether Giomer showed a better shear bond strength, it could be used instead of RMGI to restore NCCLs because of its better esthetic.

METHOD

ology: 20 maxillary and 20 mandibular intact premolars were collected. Each group of 20 samples was divided into two 10-tooth subgroups of A and B. A class V preparation was made on the buccal surface of the samples with 223 mm dimensions using a diamond bur. Also, the crossing path of the universal machine chisel was prepped with 2 mm depth up to incisal edge. For group A, after applying BeautiBond and curing it, Beautifil II Giomer was placed in nylon cylinders and the cylinders were placed in the middle cervical region and cured for 20 s. For group B, 1 spoon powder of Fuji II RMGI was mixed with two drops of its liquid and transported to nylon cylinders and placed in the middle cervical region, then cured for 20 s. The nylon cylinders were removed from all 40 samples. Then, all teeth were thermocycled and then tested using a universal machine with the force of 20 MPa and the speed of 1 mm/min until they fractured to assess their shear bond strength. The obtained data was analyzed using SPSS v.26. The significance level was considered 0.05.

RESULTS

There was no significant difference between Giomer (4.97 ± 2.36) and the resin-modified glass ionomer (3.41 ± 2.71) groups as regards their shear strength (p = 0.059). Likewise, there was no significant difference in shear bond strength between Giomer and RMGI groups as regards jaw type (P = 0.326).

CONCLUSION

The paper suggests that Giomer and resin-modified glass ionomer groups did not differ significantly in terms of their shear bond strength and that both can be utilized to treat Class V lesions. Furthermore, there was no significant difference between the shear bond strength in terms of jaw type.

摘要

引言

有几种用于修复非龋性颈部病变（NCCLs）的美容修复材料。本研究的目的是明确并比较聚酸改性复合树脂（Giomer）和树脂改性玻璃离子水门汀在V类洞修复中的剪切粘结强度，以便确定由于Giomer具有更好的美观性，若其显示出更好的剪切粘结强度，是否可以替代树脂改性玻璃离子水门汀来修复NCCLs。

方法

收集20颗上颌和20颗下颌完整的前磨牙。每组20个样本被分为A和B两个10颗牙的亚组。使用金刚石车针在样本颊面制备尺寸为2×2×3mm的V类洞。此外，通用机用凿子到达切缘的交叉路径预备2mm深度。对于A组，涂抹BeautiBond并固化后，将Beautifil II Giomer置于尼龙柱中，然后将尼龙柱放置在颈部中间区域并固化20秒。对于B组，将1匙富士II型树脂改性玻璃离子水门汀粉末与两滴液体混合，转移至尼龙柱中，放置在颈部中间区域，然后固化20秒。从所有40个样本中取出尼龙柱。然后，对所有牙齿进行热循环处理，然后使用万能试验机以20MPa的力和1mm/min的速度进行测试，直至牙齿断裂，以评估其剪切粘结强度。使用SPSS v.26对获得的数据进行分析，并将显著性水平设定为0.05。
