This study compared the dentinal tubule penetration of NeoSEALER Flo bioceramic sealer using single cone and cold lateral compaction obturation techniques.
Eighteen extracted single-rooted mandibular premolars were randomly divided into two groups (n=9) according to the obturation technique used. The maximum penetration depth in microns, percentage of penetration depth, and percentage of penetration area of the NeoSEALER Flo bioceramic sealer were assessed using confocal laser scanning microscopy at different root levels; coronal, middle, and apical. Data was statistically analyzed using Kruskal-Wallis's test followed by Dunn's post hoc test with Bonferroni correction and Friedman's test followed by Nemenyi post hoc test with the significance level set at p<0.05.
The single cone obturation technique has shown a statistically significantly higher percentage area of NeoSEALER Flo penetration than the lateral compaction technique at the coronal root level only. Otherwise, both obturation techniques have shown no statistically significant differences in NeoSEALER Flo penetration distance, percentage of penetration distance, and percentage of area penetration at the middle and apical root levels.
The single cone obturation technique can be used with bioceramic sealers yielding comparable results to the cold lateral compaction technique. (EEJ-2024-12-192).
本研究比较了使用单锥和冷侧向加压充填技术时NeoSEALER Flo生物陶瓷封闭剂在牙本质小管中的渗透情况。
根据所使用的充填技术,将18颗拔除的单根下颌前磨牙随机分为两组(n = 9)。使用共聚焦激光扫描显微镜在不同牙根水平(冠部、中部和根尖部)评估NeoSEALER Flo生物陶瓷封闭剂的最大渗透深度(以微米为单位)、渗透深度百分比和渗透面积百分比。数据采用Kruskal-Wallis检验,随后进行Dunn事后检验并采用Bonferroni校正,以及Friedman检验,随后进行Nemenyi事后检验,显著性水平设定为p<0.05。
仅在冠部牙根水平,单锥充填技术显示NeoSEALER Flo渗透的面积百分比在统计学上显著高于侧向加压技术。否则,在中部和根尖部牙根水平,两种充填技术在NeoSEALER Flo渗透距离、渗透距离百分比和面积渗透百分比方面均未显示出统计学上的显著差异。
单锥充填技术可与生物陶瓷封闭剂配合使用,其效果与冷侧向加压技术相当。(EEJ - 2024 - 12 - 192)
