“…When mixed with zinc oxide, eugenol forms a material which has restorative and prosthodontic applications in dentistry. However, the effect of these compounds on the dental erosion and demineralization of dental hard tissues are less well understood [26]. Based on data obtained from our study, clove oil and its two active principles may positively affect the dental erosion process of apple juice through distinct mechanisms.…”

The dental erosion or decalcification of enamel is a significant clinical problem. Apple acidic beverages are thought to increase the potential for dental erosion. The purpose of this in vitro study was to investigate the effect of clove essential oil (CEO) and its active principles on tooth decalcification of apple juices. On GC-MS analysis, CEO showed a high content of eugenol (58.29%) and eugenyl acetate (19.10%). Teeth specimens were randomly divided into 5 treatment groups: control, CEO, eugenol, eugenyl-acetate, and fluoride. The specimens were exposed for 24 h and were analyzed for calcium contents using Inductively Coupled Plasma with Optical Emission Spectroscopy (ICP-OES). Data were analyzed using student t-test (P < 0.05). CEO, eugenol, and eugenyl-acetate significantly decreased the decalcification of tooth by the apple juice to only 17, 24, and 21 mgL−1, respectively. Hemolytic activity on human erythrocytes was studied to exclude the possibility of further associated cytotoxicity. It was observed that the CEO and its two lead molecules inhibit the decalcification and/or promote the remineralization caused by the apple juices. The effect of the test compounds appears to be distinct like that of fluoride treatment. CEO may, therefore, serve to be a promising adjunct to fluoride in the treatment of root caries during minimally invasive therapy.

“…The adhesion of Grossman type root canal sealers to dentin is established by electrostatic bonding and not by its penetration into the dentinal tubules 16 . The low bond strength established with Group 1 may be explained by a chelating reaction that occurs while the zinc oxide-eugenol mixture is setting 31 . This reaction affects both the gutta-percha core material and the root canal dentin.…”

. Methods: Thirty extracted single-root human teeth of similar sizes and circular canals were prepared using #3 and #2 Gates Glidden drills in the cervical portion of the canal and K3 ® rotary instruments to a size #25/0.06 to working length. Irrigation with 0.5 mL 2% chlorhexidine gel was used before and 1 mL saline after each instrument. The smear layer was removed with 3 mL 17% EDTA for 3 min. The samples were sectioned horizontally into eight 1±0.1 mm-thick serial slices and then the push-out test was carried out. Two-way analysis of variance (ANOVA) and the post-hoc Tukey test were used for the analysis of the data with a significance level of 5%. Results: AH Plus presented significantly higher bond strengths (p<0.05) than the other sealers, while MTA Fillapex showed the lowest bond strengths (p<0.05). Conclusions: The present study concluded that EndoFill ® sealer and MTA FillApex ® core combination were not superior to AH Plus ® sealer and gutta-percha core combination.

“…Zinc oxide is a base that can be prepared in three different ways; from oxidation of the metal; by direct decomposition of the zinc ores in air; or by thermal decomposition of zinc compounds [2]. Mixed together, the setting reaction of zinc oxideeugenol is a classical acid -base reaction giving a salt plus water [3]. Zinc oxide plus a small amount of water gives zinc hydroxide, which in turn, with eugenol, gives zinc eugenolate plus water that returns to catalyse the reaction.…”
