Use of sodium trimetaphosphate in the inhibition of dentin matrix metalloproteinases and as a remineralizing agent
Conclusion 1.5% STMP serves as an antiproteolytic agent against matrix metalloproteinases extracted from human dentin. Furthermore, when supplemented with Ca(OH)2, 1.5% STMP may potentially induce remineralization. Clinical significance STMP can be introduced as a novel strategy that combines enzymatic inhibition and remineralizing potential, which can serve to strengthen dentin and improve stability. STMP may have potential in the treatment of demineralized dentin lesions, especially when supplemented with calcium. (Source: Journal of Dentistry)

Influence of the addition of microsphere load amoxicillin in the physical, chemical and biological properties of an experimental endodontic sealer
Conclusion The addition of up to 10% of microspheres containing amoxicillin presented antimicrobial activity and did not alter the properties of the experimental endodontic cement. Clinical significance Amoxicillin microspheres with its antimicrobial activity in root canal sealers could reduce reintervations in endodontics when persistent bacteria or reinfection takes place in root canal system.

Restoration of severely damaged endodontically treated premolars: The influence of the endo-core length on marginal integrity and fatigue resistance of lithium disilicate CAD-CAM ceramic endocrowns
Conclusions Endocrowns with both 2-mm and 4-mm long endo-cores displayed outcomes after fatigue equivalent to classical crowns. Results of this study discourage the use of flat overlays with only adhesive retention. Clinical significance When restoring extremely destroyed devitalized premolars, adhesive strategies should be coupled to a macro-mechanical retention in the root. (Source: Journal of Dentistry)

In-vitro apatite formation capacity of a bioactive glass - containing toothpaste
Conclusions The results of this lab-based study showed that the toothpaste with MFP and bioactive glass formed a fluoridated apatite in artificial saliva and in Tris buffer, as did the mixture of bioactive glass and MFP. Clinical significance The presence of fluoride in bioactive glass-containing toothpastes can potentially lead to the formation of a fluoridated apatite, which may result in improved clinical effectiveness and durability. However, this should be further tested intra-orally. (Source: Journal of Dentistry)

Does tooth loss affect dietary intake and nutritional status? A systematic review of longitudinal studies
Conclusion There is at present no strong evidence on the effect of tooth loss on diet and nutrition, with inconsistent results among the few studies identified. Additional high-quality longitudinal studies should address the limitations of previous studies identified in this review. (Source: Journal of Dentistry)

Novel self-healing dental luting cements with microcapsules for indirect restorations
Conclusions A self-healing dental luting cement was developed for the first time. It contained fine microcapsules and exhibited an excellent self-healing efficiency, even after being immersed in water for 6 months. Clinical significance The self-healing cement is promising for cementing crowns and bridges and other adhesive cement applications, to heal cracks and increase restoration longevity.

Polyols and remineralisation of enamel subsurface lesions
Conclusion This controlled in vitro study showed that polyols at physiologically relevant concentrations did not promote remineralisation of enamel subsurface lesions by facilitating calcium uptake into the lesion. (Source: Journal of Dentistry)

Interfacial degradation of adhesive composite restorations mediated by oral biofilms and mechanical challenge in an extracted tooth model of secondary caries
Conclusions Sucrose pulsing was required to induce biofilm-mediated degradation of the adhesive interface. We have presented a comprehensive and clinically relevant model to study the effects of mechanical loading and microbial challenge on the interfacial integrity of dental restorations.

Susceptibility of contemporary single-bottle self-etch dentine adhesives to intrinsic water permeation
Conclusion IB exhibits water sensitivity when bonding is performed with/without pulpal pressure. C3S exhibits water sensitivity when bonding is performed with pulpal pressure. CSBP does not exhibit water sensitivity when bonding is performed with/without pulpal pressure. Clinical significance: Intrinsic water permeation during bonding procedures significantly affects bond strength results and the resin-dentine interface of contemporary single-bottle self-etch dentine adhesive systems.

Polymerisation, antibacterial and bioactivity properties of experimental orthodontic adhesives containing triclosan-loaded halloysite nanotubes
Conclusions Adhesives doped with TCN-HNT present improved polymerisation properties and suitable bonding performance. However, adhesives containing TCN-HNT >10% might promote long-term antibacterial activity and reliable mineral deposition. Significances The use of adhesives containing triclosan-loaded halloysite represent a promising “smart” approach to bond orthodontic brackets and bands; these might prevent enamel demineralisation and induce enamel remineralisation during the treatment.

Comparison of deproteinization agents on bonding to developmentally hypomineralized enamel
Conclusions Papain-based papacarie could be an alternative deproteinization agent for bonding dental adhesive to HE. Clinical significance Papain-based papacarie, a natural deproteinization agent and a proven chemo-mechanical caries removal agent could be an alternative to NaOCl for enhancement of bond durability of adhesive restorations to HE.

Assessing the quality of dental clinical practice guidelines
Conclusion Overall, the quality of clinical dental practice guidelines is suboptimal. There is variation in the overall quality, reporting of individual items and domains of the AGREE II instrument between different dental speciality clinical practice guidelines. Guidelines based on formal evidence achieved higher quality scores. Clinical Significance Clinicians should be aware of the variation in the quality of dental clinical guidelines in particular related to methodological rigour. The use of formal evidence may be a useful indicator of their quality prior to their implementation. (Source: Journal of Dentistry)

The relationship between dentine hypersensitivity, dietary acid intake and erosive tooth wear
Conclusion Contact time between the tooth and the acid may be a more important risk factor for DH compared to frequency of dietary acid intake or frequency of toothbrushing. Other possible aetiological factors should be considered. Clinicaltrials.gov number NCT02449434 Clinical significance Increased contact time with dietary acids and sipping swishing or holding drinks in the mouth prior to swallowing should be addressed as an aetiological factor in DH. Toothpaste abrasivity and toothbrush filament stiffness may play a greater role in DH compared to frequency of toothbrushing. (Source: Journal of Dentistry)
