Controlled release of chlorhexidine from a HEMA-UDMA resin using a magnetic field
Antibacterial agents and their delivery are of great importance in medicine and dentistry, since a wide range of bacterial infections are still the major reasons for recurrent/persistent infections despite the use of antibiotics [1,2]. Biomaterial implants used in modern medicine for functional restorations are also susceptible to infections, which can lead to failure [3]. Increased application of implants in dentistry has led to significant numbers of patients developing peri-implantitis (47.1% prevalence with mean functional loading of 10 years) [4].

Effect of matrix metalloproteinase 8 inhibitor on resin –dentin bonds
The longevity of resin –dentin bonds is consistently a focus of research in contemporary adhesive dentistry due to the reduction of bond strength over time. The bonded interface is mainly damaged by enzymatic degradation of the collagen matrix [1,2]. Matrix metalloproteinases (MMPs) are present in dentin matrices, which belong to a class of zinc- and calcium-dependent endopeptidases [1,3]. They have been shown to be related with the collagen degradation in the hybrid layers, which may be due to the low-pH environment, the activity of tissue inhibitors of MMPs (TIMPs), and the interaction with cysteine cathepsins.

Profiling cytokine levels in chlorhexidine and EGCG-treated odontoblast-like cells
Cytokines are produced by different cells of the body and although their grouping into cytokine families is not consensual in the literature, it is accepted that they can be arranged into structural families that include: interleukins, chemokines, interferons, transforming growth and tumor necrosis factor families. Families of cytokines share sequence similarity and exhibit homology and some promiscuity in their reciprocal receptor systems. Despite being structurally related, members belonging to the same cytokine family may exhibit rather diverse functions. (Source: Dental Materials)

Evaluation of biofilm formation on novel copper-catalyzed azide-alkyne cycloaddition (CuAAC)-based resins for dental restoratives
The oral cavity is a complex environment where over 700 bacterial species have been detected in the oral common microbiota [1 –4]. Within this diverse community of bacteria found in the mouth, Streptococcus mutans, due to its acidogenic nature and its ability to form biofilms on tooth surfaces, is one of the primary species associated with human dental caries and secondary caries formation [5,6]. Recent studies have also indicated that numerous other oral bacteria, most notably those that are acid producing, work together to form polymicrobial biofilms that ultimately initiate and further develop tooth decay [7–10].

Features of fracture of prosthetic tooth-endocrown constructions by means of acoustic emission analysis
Prosthetic treatment of damaged teeth aims at restoring all their parameters, both esthetic and functional. Denture technologies are constantly developing and at present there are numerous means for an effective, complete or partial, restoration of lost tooth crowns. Pissis [1] proposed the endocrowns as an alternative crown for molars, depending on the availability of the remaining tooth structure. The term ‘endocrown’ was first defined by Bindl and Mörmann [2] as a monolithic ceramic bonded construction fixed to the tooth structure by adhesive material. (Source: Dental Materials)

Application of radiopaque micro-particle fillers for 3-D imaging of periodontal pocket analogues using cone beam CT
Key hallmarks of periodontitis (PD) are the destruction of alveolar bone, apical migration of junctional epithelium, and loss of connective tissue attachment to the tooth/root surface. This leads to the formation of periodontal pockets (PPs) between the tooth and gingiva/bone [1]. Measurement of the depths of the PP around all teeth (along with clinical attachment levels and bone loss) is critical for accurate diagnosis and prognosis of the dentition, as well as for evaluation of the response to therapy for treatment planning purposes [2].
