The purpose of this in vitro study was to evaluate erosive wear and change in color of high-viscosity glass ionomer cements after pH cycling in two erosive media. There were 3 experimental groups with 22 samples each, (I) EQUIA Forte HT without coat, (II) Fuji IX and (III) Ketac Universal Aplicap. Each group was randomly divided into three subgroups (n = 6–8) further exposed to different environments, (1) distilled water, (2) green tea (pH 3.78) and (3) Aceto balsamico vinegar (pH 3.0). Mass and L* a* b* values were recorded before and after pH cycling. The samples in subgroups 2 and 3 were exposed to the acidic media two times a day for 10 min, over a period of 14 days. The differences among materials and erosive effects of the three media were tested using three-way analyses of variance with post hoc LSD test at the significance level p < 0.05. The effect of pH cycling in Aceto balsamico and green tea was degrading for all three materials. pH cycling in Aceto balsamico caused significantly higher erosive wear than pH cycling in Fuzetea and storage in distilled water, in all materials (p < 0.05). pH cycling in both acidic media and in the control group resulted in a significant change in L* a* and b* (p < 0.05). The L* value decreased significantly and the a* and b* values increased significantly (p < 0.05).

The welfare state takes a stand against the demands of modernization by seeking to care for society’s most vulnerable groups. People with disabilities are in a particularly vulnerable position, facing numerous obstacles to the labor market. Social enterprises, especially work integration social enterprises (WISE), can provide an important access point for their integration. The present analysis of five post-socialist countries in the European Union – Poland, Slovenia, Slovakia, Czech Republic, and Croatia – identifies several general characteristics essential for WISE development, such as the existence of some form of financing as well as certain legislative and institutional frameworks that remain underdeveloped. Lack of awareness and promotion of WISEs as well as a shortage of necessary skills have delayed WISE development in these countries, particularly in Croatia, where WISEs are few with small numbers of employees. This study provides recommendations for improving the situation of WISEs in Croatia in order to help them facilitate the employment and social inclusion of people with disabilities and other vulnerable groups.

BackgroundPeri-implantitis is a chronic, marginal and progressive infection of soft and hard tissue that surrounds dental implants, which results in the loss of the supporting bone, caused by similar microbes as adult periodontitis. Staphylococcus aureus and Candida albicans are microorganisms that are not primarily associated with periodontitis, but certain studies identified them in periimplant pockets. AimsThe current review aimed to assess the role of Candida species in peri-implant diseases.

Background : A human periodontal ligament fibroblast cell line showed a very promising growth reaction to the mineralized dentin. The mineral and organic matrix compositions of a tooth, dentin, and cementum are almost identical to membranous bone, although, compared to bone, teeth contain more mineral. This feature may be beneficial for volume maintenance since at the remodeling stage dentin graft is resorbed slowly. As a supplement of bone graft material, dentin particulate autograft could be beneficial. Aim/Hypothesis : The aim of this pilot clinical study was to assess efficacy and predictability of dentin particulate autograft as regenerative treatment for alveolar ridge augmentation and two stage implant placement using CBCT radiographic analysis. Materials and Methods : The sample of presented study consisted of 8 patients, with insufficient width of alveolar ridge in lateral lower jaw. After surgical removal of third molar or periodontally compromised tooth, a dentin autograft was prepared according to manufacturer recommendations. Clean extracted teeth were dried and ground in a sterile chamber of the Smart Dentin GrINDIAr ® unit (KometaBio Inc., Cresskill, USA). The particulate teeth were immersed in a basic alcohol cleanser to dissolve all organic remnants and bacteria and dehydrated. The particles were rinsed twice with sterile phosphate-buffered saline solution. The platelet-rich fibrin (PRF) membranes were prepared. Graft material was used for ridge augmentation and covered with PRF membranes. After 5 months of healing CBCT scan were made. During implants placement homogeneous integration of dentin particulate was found. Dental implants (BEGO Semados ® SC BEGO, Germany) were inserted and restored by titanium abutment and zirconia crown. Results : Clinical re-entry, prior to dental implants placement confirmed a homogeneous integration of dentin autograft and bone-like appearance in former grafted area. Six months after implants placement CBCT scans were obtained as part of the standard procedure. The radiographic images of the target areas revealed no grafted bone resorption around the implants. All patients were followed for 6 months after loading through clinical follow-ups and control CBCT scans. No resorption of the autograft around inserted implants were found. Conclusions and Clinical Implications : Within its limitation, the present pilot clinical study revealed that autologous dentin particulate autograft may serve as an alternative autologous bone substitute to support alveolar ridge augmentation and two-stage implant placement.
