“…In this way it could stabilize the collagen and maintain it in an expanded state which influence the bond strength of the restoration and their durability maintaining higher values of bond strength. Moreover ,white tea is considered as antioxidant which prevents the action of oxidants that might be released into dentin through aging which prevent the harmful effect of free radicals thus preserving its structural integrity (25)(26)(27) .These results are in accordance with other studies (28,29) which found that catechins found in large amounts in white tea increased the bond strength. On the contrary other study (30) found that application of tea showed no significant difference in immediate bond strength values but it was considerable stable in the long-term.…”

Purpose: This study was conducted to evaluate the effect of egg shell and white tea dentin pre-treatment on microtensile bond strength between resin composite and dentin surface. Materials and Methods: Forty-five extracted molar teeth were divided into three subgroups according to dentin pretreatment ; with no treatment (control ), Egg shell, and white tea. Each group was subdivided for microtensile testing into three equal subgroups, either after 24 hours (T0), after1 month (T1), and after 3 months (T2).The occlusal enamel was removed. And according to each group one of pretreatments was used. Resin composite blocks were fabricated on dentin after application of self etch adhesive. The teeth were longitudinally sectioned to get composite-dentin beams, two central beams were selected from 45 teeth in order to have 90 beams. Specimens were assessed after 2 storage periods in artificial saliva: either one month (T1) or three months (T2) storage period. Specimen were subjected to microtensile bond strength testing. Results: at T0, there was no statistically significant difference in mean μTBS between different dentin pre-treatments, while at T1 and T2, white tea group showed significantly the highest μTBS mean values, followed by egg shell group, then control group. Conclusion: Natural remineralizing agents could enhance microtensile bond strength of universal bonding system in self etch mode, and remineralizing potential of natural agents has stabilized by time.

Purpose:The aim of this study was to evaluate the remineralizing effect of white tea, green tea and casein Phosphopeptide amorphous calcium phosphate (CPP-ACP) on demineralized enamel by microhardness testing. Materials and Methods:A total of 24 enamel samples were divided according to enamel pretreatment after artificial demineralization of 8 samples each, group I (white tea + CPP-ACP, group II (green tea + CPP-ACP) group III (CPP-ACP), microhardness was evaluated at baseline, after demineralization and after treatment for all enamel samples.Results: there was insignificant difference between groups where group I was insignificantly the highest, followed by Group II & group III.Conclusions: the use of CPP-ACP with tea increased the remineralization potential.

Impact of Dentine Pretreatment with Matrix Metalloproteinase Inhibitors on Bond Strength of Coronal Composite Restorations: A Systematic Review and Meta-analysis of In Vitro Studies

et al. 2022

Objectives Matrix metalloproteinase (MMP) enzymes participate in collagen matrix degradation, including in dentine, potentially compromising bond strength. Therefore, MMP inhibitors have been hypothesized to improve restoration bond strength and stability. This systematic review aimed to evaluate the influence of different MMP inhibitors applied as dentine surface pretreatments on the immediate (24 hours) and longer term (months) bond strength of direct coronal composite restorations. Materials and Methods This systematic literature review followed the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. A systematic literature search of three databases (Ovid MEDLINE, Ovid Embase, and Google Scholar) was conducted independently by two reviewers from inception to April 2022. An adapted quality assessment tool was independently applied by two reviewers for risk of bias assessment. Statistical Analysis RevMan v5.4 software was used for meta-analyses. A random-effects model was used to generate mean differences with 95% confidence intervals for treatment and control comparisons. The Q-test and I2 -test were used to test for heterogeneity. The proportion of total variance across studies attributable to heterogeneity rather than chance was calculated. Overall effects were tested using the Z-test, while subgroup differences were tested using Chi-squared tests. Results Of 934 studies, 64 studies were included in the systematic review and 42 in the meta-analysis. Thirty-one MMP inhibitors were reported, three of which were included in the meta-analysis: 2% chlorhexidine (CHX), 0.3 M carbodiimide (EDC), and 0.1% riboflavin (RIBO). Pretreatment with 2% CHX for 30 and 60 seconds did not significantly improve bond strength compared with controls either immediately or after long-term ageing. However, pretreatment with 0.3 M EDC and 0.1% RIBO (but not CHX) significantly improved bond strength compared with control groups both immediately and over time. Most studies showed a medium risk of bias. Conclusions These in vitro findings pave the way for rationale clinical trialing of dentine surface pretreatment with MMP inhibitors to improve clinical outcomes.
