Comparison of the newer preventive therapies on remineralisation of enamel in vitro
Conclusions Both MI Paste and MI Paste Plus when used in conjunction with 1450ppm F did not show a significant increase in efficacy for the remineralisation of bovine enamel subsurface lesions in the model used in this study. Clinical significance Newer preventive agents such as MI paste and MI paste plus are advocated as promoting remineralisation when used in addition to routine oral care. This in vitro study shows that they may have a limited value in promoting remineralisation over and above that of 1450ppm F toothpaste used twice a day. (Source: Journal of Dentistry)

The effect of local and systemic statin use as an adjunct to non-surgical and surgical periodontal therapy —A systematic review and meta-analysis
Conclusions Significant additional clinical and radiographic improvements are obtained after local, but not systemic, statin use as an adjunct to SRP in deep pockets associated with intrabony defects and seemingly with furcation defects; intrasurgical statin application seems similarly beneficial. Confirmation of these results, and especially of the effect size, from other research groups is warranted. (Source: Journal of Dentistry)

In Vitro Efficacy of Essential Oil Mouthrinse versus Dentifrices
Conclusions Within typical exposure times, the EO-containing mouthrinse can penetrate deep into the accumulating plaque biofilm compared to the chemotherapeutic dentifrice slurries, and may provide an efficacious alternative to triclosan, when used as an adjunct with a mechanical oral care regimen. Clinical Significance Using viability mapping and CLSM, this study demonstrated that EO-containing mouthrinse penetrates and kills microorganisms deeper and more effectively in plaque biofilm in typical exposure times when compared to dentifrice chemotherapeutic agents, providing an efficacious alternative to triclosan or stann...

A qualitative study of patients ’ views of techniques to reduce dental anxiety
Conclusions Preparatory information may need to be tailored and comprehensive, yet dissociative and reassuring. Dentally-anxious people might want a sense of control and shared-decision making. They may not want dentists to understate the treatment procedures and risks to make them feel better temporarily. Clinical significance Dental anxiety affects between 10 and 60% of the population. Participants in this study suggested different ways the dental team could help their anxiety. Therefore, it is key for whole dental team to find out what could be done to help dentally anxious patients. (Source: Journal of Dentistry)

Influence of specimens ’ geometry and materials on the thermal stresses in dental restorative materials during thermal cycling
Conclusions Maximum absolute stress values were found to vary between 2–4MPa, which might not be critical even for ceramics. During multi-cycle testing these stresses would cause different fatigue in various locations. The zirconia-based specimens and zirconia-based restoration (crown) exhibited the most similar stress states. Thus it might be recommended to use these geometries for fast screening of the materials for this type of restorations. (Source: Journal of Dentistry)

Effects of smear layer removal agents on the physical properties and microstructure of mineral trioxide aggregate cement
Conclusion MA had more detrimental effect on the physical properties of MTA and EDTA was more detrimental to the hydration of MTA. Clinical significance The present study highlights the effect of newer chelating agents on the physical properties and microstructure of MTA. Preventing the deterioration of MTA is important for its long term success in endodontic procedures. (Source: Journal of Dentistry)

Topical Silver Diamine Fluoride for Dental Caries Arrest in Preschool Children: A Randomized Controlled Trial and Microbiological Analysis of Caries Associated Microbes and Resistance Gene Expression
Conclusion Average proportion of arrested caries lesions in the silver diamine fluoride group was higher (0.72; 95% CI; 0.55, 0.84) than in the placebo group (0.05; 95% CI; 0.00, 0.16). Confirmatory analysis using generalized estimating equation log-linear regression, based on the number of arrested lesions and accounting for the number of treated surfaces and length of follow-up, indicates the risk of arrested caries was significantly higher in the treatment group (relative risk, 17.3; 95% CI: 4.3 to 69.4). No harms were observed. RNA sequencing analysis identified no consistent changes in relative abundance of caries-ass...

Organic degradation potential of a TiO2/H2O2/UV –vis system for dental applications
Conclusions Low H2O2 concentrations (1.0mM–3.5mM) and visible light (405nm) used in combination with rutile TiO2 particles showed the highest RhB degradation capacity. Clinical significance A combination of TiO2 particles and H2O2 exposed to low energy UV or high energy visible light has an organic degradation capability that could be utilized in applications to kill or inactivate bacteria on medical devices such as dental implants for treatment against, e.g., peri-implantitis.

Fluoride concentration and amount of dentifrice influence enamel demineralization in situ
Conclusions The treatment intensity has a significant influence on the development of caries lesions in situ. Clinical significance: The intensity of treatment (amount of dentifrice×concentration) during brushing seems to be a more relevant parameter of clinical efficacy than simply observing the F concentration of the product. The use of a small amount of CD significantly reduced the protective effects against enamel demineralization. (Source: Journal of Dentistry)

Effects of small-grit grinding and glazing on mechanical behaviors and ageing resistance of a super-translucent dental zirconia
Conclusions The results suggest that small-grit grinding is beneficial to the strength and ageing resistance of the super-translucent dental zirconia; however, glazing is not necessary and even impairs the strength for the super-translucent dental zirconia. Clinical significance This study is helpful to the researches about dental grinding tools and maybe useful for dentists to choose reasonable zirconia surface treatments.

Silver Diamine Fluoride remineralized artificial incipient caries in permanent teeth after bacterial pH-cycling in-vitro
Conclusion The adjunctive use of 38% SDF enhances the remineralization of initial carious lesions based on mineral density, depth, and remineralization percentage compared with the use of 1000ppm fluoride toothpaste alone. SDF might be used as an adjunct to fluoride toothpaste to remineralize incipient caries lesions on smooth tooth surfaces. Clinical significance In non-compliant patients, the application of 38% SDF might be used as an adjunct to fluoride toothpaste, to remineralize incipient caries lesions of permanent teeth where esthetics is not a concern. 270W (Source: Journal of Dentistry)

Tooth Colour and Whiteness: A review
Conclusions The appearance and colour of teeth is a common concern for patients across many populations and is associated with an increased desire for treatments that improve dental aesthetics, including tooth whitening. The application of colour science in dentistry has allowed the precise description of tooth colour and whiteness. Coupled with the advances in instrumental tooth colour measurement, such as spectrophotometers, colorimeters, spectroradiometers and digital imaging systems, these parameters are quantifiable in a reproducible and robust manner. These principles have been applied to the tooth colour distributio...

The use of tailored subheadings was successful in enhancing compliance with CONSORT in a dental journal
Conclusion Enhanced compliance of submitted RCTs was found with use of a bespoke approach to trial presentation utilizing CONSORT item subheadings. The improvement in initial submissions is particularly encouraging as this arose without input either from peer reviewers or journal editors. This simple approach may have wider applicability.

All-ceramic, bi-layered crowns supported by zirconia implants: Three-year results of a prospective multicenter study
Conclusion Veneered, zirconia-based SCs supported by zirconia implants satisfied patients’ needs highly. However, significant incidence of chipping and roughness of the veneering ceramic may compromise the clinical long-term outcome for this indication. Clinical significance Posterior, zirconia-based SCs supported by zirconia oral implants entirely survived the follow-up period of 3 years, but two major chippings, one a significant marginal opening and one pronounced over-contouring, resulted in a reduced KM success estimate of 87.5% after 36 months of observation.
