Abstract

AIM AND OBJECTIVE

This study was carried out to comparatively assess the efficiency of four methods of obturation viz Lentulo spiral, Navi tip syringe, Bi directional spiral, and Past inject carrier in deciduous teeth using vista scan.

MATERIALS AND METHODS

A total sample of 100 primary root canals [4 groups of 25 canals each] with 2/3 of root length were selected and randomly allocated into four different obturating techniques, i.e., Group I: Lentulo spiral, Group II: Navi tip syringe, Group III: Bi directional spiral, and Group IV: Past inject carrier. The quality of obturation [Coll and sadrain, 1996] and presence or absence of voids were evaluated by using Vista scan. The recorded data was statistically analyzed.

RESULTS

The highest mean rank value of optimally filled canals was obtained by Group IV [58.00] followed by Group I [50.00] with no significant difference. The highest mean rank value of under filled canals and over filled canals were obtained by Group III and Group II, respectively, and these results were statistically significant. All the four obturation techniques showed presence of voids with no significant difference.

CONCLUSION

Both Lentulo spiral and Past inject carrier were equally efficient in attaining an optimally filled homogenous obturation in deciduous teeth.

摘要

目的

本研究旨在通过Vista扫描比较评估四种乳牙根管充填方法，即Lentulo螺旋充填器、Navi tip注射器、双向螺旋充填器和Past inject输送器的效率。

材料与方法

选取100个乳牙根管样本（每组25个根管），根管长度为根长的2/3，随机分为四种不同的充填技术组，即：第一组：Lentulo螺旋充填器；第二组：Navi tip注射器；第三组：双向螺旋充填器；第四组：Past inject输送器。使用Vista扫描评估充填质量（Coll和Sadrain，1996年）以及是否存在空隙。对记录的数据进行统计学分析。

结果

第四组（58.00）获得的最佳充填根管的平均秩次值最高，其次是第一组（50.00），两者无显著差异。第三组和第二组分别获得充填不足根管和充填过度根管的最高平均秩次值，这些结果具有统计学意义。所有四种充填技术均显示存在空隙，无显著差异。

结论

Lentulo螺旋充填器和Past inject输送器在实现乳牙最佳充填均匀性方面同样有效。
