Clove leaf oil as good as autoclaving for disinfection of dental equipment, finds study

The study was conducted to compare and evaluate the disinfecting efficacy of four different herbal oils with standard autoclaving against Enterococcus faecalis (E. faecalis). Fifty round burs were infected with E. faecalis and dipped into the chemical test solution for 10 min. The disinfecting efficacy for each test chemical was checked using the culture method on a blood agar plate and peptone water test to check for turbidity. Clove leaf oil and Tulsi leaf oil have very good antimicrobial efficacy against E. faecalis which are similar and comparable to that of autoclaving.

This study aimed to compare the efficacy of pomegranate peel extract (PPE) oil, Garlic oil, Tulsi leaf oil, and Clove leaf oil with standard autoclaving on dental round burs tested against E. faecalis. Settings and Design: The disinfecting capability of four different experimental oils against autoclave was evaluated on 50 round burs exposed to E faecalis in an In-vitro study.

A total of 50 round dental burs were exposed to E. faecalis and the disinfecting capability of four different experimental oils against autoclave was evaluated by counting colony-forming units (CFUs) and turbidity test.

The results of the study are:

• Statistical analysis was performed using SPSS version 20.0 (IBM), Chicago.
• The CFUs between the five groups (I, II, III, IV, V) were compared using the Chi-square test.
• The level of significance was kept at 5%.
• Clove leaf oil showed the best disinfection efficacy comparable to autoclaving, followed by Tulsi leaf oil with no statistically significant difference between them, whereas garlic oil and PPE oil were significantly less effective against E. faecalis.

Thus, clove leaf oil and Tulsi leaf oil can be used for disinfecting dental burs, infected with E. faecalis, as alternatives to autoclaving.
