In vitro study shows different cavity designs and irrigation solutions impact calcium hydroxide removal effectiveness, suggesting alternatives to EDTA.

Key Points

This research aims to determine how various access cavity designs and irrigation solutions affect the removal efficacy of calcium hydroxide from root canals.
Eighty-four mandibular molars were categorized into three access cavity groups: traditional, ultra-conservative, and support access cavities.
Each access cavity group was subdivided into four subgroups based on the irrigation solutions used: saline, 17% EDTA, 70% ethanol, and 0.2% chitosan.
Statistical analysis utilized two-way ANOVA followed by Tukey post hoc tests with 95% confidence intervals.
The truss access cavity design resulted in cleaner canals than the ultra-conservative access cavity (p < 0.05).
There was no significant difference in cleaning effectiveness between truss and conventional access cavities (p > 0.05).
70% ethanol was significantly more effective than 17% EDTA and saline for calcium hydroxide removal (p < 0.05), while 70% ethanol and 0.2% chitosan showed similar effectiveness (p > 0.05).
