Background:Antibacterial treatments currently used for treatment cause several side effects, and bacterial resistance to the antibiotics is also increasing. Therefore, there is need to find better alternatives. Essential oils (EOs) have been used for treatment of various ailments since ancient times and have gained popularity over the years. Safety and efficacy of EOs have been proved by several clinical trials. This review gives an overview on the EOs, their uses, and adverse effects.Materials and Methods:A literature search was performed in the PubMed for clinical trial studies and review articles on EOs published up to February 2015. The search was performed during March 2015. The following keywords were used: “Lavender essential oil,” “cinnamon oil,” “clove oil,” “eucalyptus oil,” “peppermint oil,” “lemon EOs,” and “tea tree oil.”Results:Total 70 relevant articles were found in PubMed database. After screening of abstracts, 52 articles were selected to be included in the present review.Conclusion:On the basis of the available information, it can be concluded that EOs have the potential to be developed as preventive or therapeutic agents for various oral diseases, but further clinical trials are required to establish their safety and efficacy.

Introduction: This study was designed to assess the effect of two bleaching agents on the disintegration tendency of three types of glass ionomers.

Objective:This study was designed to evaluate the effect of two bleaching agents on the fluoride release of three types of glass ionomer materials.Materials and Methods:A total of 90 specimens of the tested materials (Ketac Fil, Photac Fil and F2000) were prepared by a split Teflon ring with an internal diameter of 5 mm and thickness of 2 mm. The tested materials were applied and bleached according to manufacturer instructions. Fluoride release measurements were made by using specific ion electrode.Results:Results revealed that bleaching with opalescence Xtra caused little increase in fluoride release from Ketac Fil and Photac Fil but has no effect on F2000. However, Opalescence Quick had no significant effect on the three tested materials.Conclusions:Bleaching effect on fluoride release is material dependent and time has a significant role on fluoride release.
