Methodology: 171 females with periodontal disease (71 subjects with gingivitis and 100 subjects with periodontitis) and 168 males with periodontal disease (72 subjects with gingivitis and 96 subjects with periodontitis) were included in the study. Clinic periodontal parameters (probing pocket depth, gingival index, plaque index, and bleeding on probing) were used in the periodontal examination. Depressive symptoms were determined by the Beck Depression Inventory (BDI). According to BDI scores, 150 depressed subjects (77 females and 73 males) and 189 non-depressed subjects (94 females and 95 males) were present. Results: There were similar BDI scores observed in female and male participants. All periodontal parameters were higher in males than females. While plaque index and gingival index were higher in depressed females than non-depressed females, probing depth was similar in female subgroups. Besides, all periodontal parameters were similar in male subgroups. When the relationship between periodontal status and depression scores in women was evaluated, women with periodontitis had higher BDI scores than women with gingivitis. In male subjects, there was no difference in BDI scores in individuals with periodontitis and/or gingivitis. Conclusion: It can be said that depression is a risk factor that negatively affects periodontal status for females, who were more vulnerable to stress and pain than males.

Methodology: A total of 96 lithium disilicate glass-ceramic specimens were prepared and divided into four groups: control, rough, D+Z polished, and OptraFine polished. A total of 16 subgroups were obtained based on four combinations of three bacteria. After adding artificial saliva to the surface, all specimens were incubated in suspensions prepared for bacterial combinations. Bacterial adhesion values in the colonies formed were obtained according to the colony-forming unit (CFU) system. Results: The highest Sa values were found for the rough group, followed by the OptraFine polished, D+Z polished, and control groups, but, except for the control group, the values were statistically similar (p > 0.05). The difference between S. salivarius and the triple bacteria combination was statistically significant for the S. salivarius CFU values in the control group. The difference between S. salivarius, S. salivarius + S. mutans, and the triple bacteria combination groups was significant for the rough group (p < 0.05). S. salivarius alone accumulated the most on all specimen surfaces. In the control group, a high level (r=0.6-0.8) of positive correlation was found between the S + Mit group and the S + Mit + Mut group. In the rough group, a high (r>0.8) positive correlation was found between the S + Mut and S + Mit + Mut groups in terms of S. salivarius adhesion. Conclusion: For lithium disilicate glass-ceramic material, polishing systems are not sufficiently efficient after the glaze layer has been removed. How to cite this article: Kavaz T, Özdemir H.

In this case report, it is aimed to eliminate the existing aesthetic problem by treating enamel hypomineralization in the maxillary central and canine teeth with the resin infiltration technique.\u0000Methodology: A 17-year-old male patient was referred to our clinic because of an aesthetic problem caused by a white spot lesion in his maxillary central and canine teeth. After clinical and radiological examination, his treatment options were evaluated, and we decided to treat it with the resin infiltration technique. After cleaning the surfaces of the teeth with a prophylaxis pad (Ultrapro Tx, Ultradent, South Jordan, UT, USA), isolation was achieved by applying a gingival barrier (Gingival Barrier, SDI, Bayswater, VIC, Australia). The adjacent teeth were protected using Teflon tape. A 15% hydrochloric acid gel (Icon Etch, DMG, Hamburg, Germany) was applied to the enamel surfaces for two minutes by mixing with a brush. After, the acid was removed using a water spray for 30 seconds. Ethanol (Icon Dry, DMG, Hamburg, Germany) was applied for 30 seconds and air dried. Then, a low-viscosity resin infiltrant (Icon Infiltrant; DMG, Hamburg, Germany) was applied to the tooth surfaces for three minutes by slight massage. After the application, the resin was light polymerized for 40 seconds (D-Light Pro, GC, Tokyo, Japan). The whole procedure was performed in such a way that there were two consecutive cycles.\u0000Results: Aesthetics improved after the procedure.

Buccal enamel surfaces of bovine incisors were wet polished and then were divided into three groups: sound enamel; demineralized enamel; demineralized enamel infiltrated with a low-viscosity resin (ICON, DMG, Hamburg, Germany). After acid-etching with 37% phosphoric acid for 20 seconds, a two-step, total-etch adhesive (Single Bond 2, 3M ESPE, St. Paul, MN, USA) was applied using a microbrush for 20 seconds, followed by gentle air-drying for 5 seconds. The adhesive was light-cured for 10 seconds. Following the adhesive application, flowable composite resin (Filtek Supreme Flowable, 3M ESPE, St. Paul, MN, USA) was gently placed into a microtubule and was photopolymerized using an LED curing unit (Elipar Deep Cure; 3M ESPE, St. Paul, MN, USA).

No complications such as infection, radiolucency, or pus were detected after two dental implants were placed in the mandible and after three months recovery period. The right mandibular dental implant failure occurred due to compression of the dental implant and healing head during the delivery of the patient’s removable prosthesis. Following implant socket healing after two months, the 4.8 mm diameter implant was placed immediately after.

A home-bleaching agent containing 16% carbamide peroxide was applied in three repeated periods (10 days, 20 days, and 30 days of exposure). A surface profilometer was used to determine the roughness average (Ra) values of the specimens. The data obtained were statistically analyzed using repeated measures of the analysis of variance (ANOVA) and Bonferroni post-hoc test at a 5% level of significance.\u0000Results: All materials exhibited a rougher surface after the first treatment period (10 days of exposure). The roughness of Group VM II continued to increase for up to 20 days. With the exception of Group LU, all groups exhibited a significantly rougher surface after 30 days of exposure compared to the baseline values (p < 0.05). The greatest variation in surface roughness was observed for the ceramic-based groups (VM II, EMP, and EMAX) rather than the hybrid groups (LU and VE).\u0000Conclusion: Patients with ceramic-based CAD-CAM restorations should be careful during home-bleaching treatment, especially when repeated applications are involved.

With the development of technologies, the number of different composites used in dental treatment has increased. With contemporary patients’ aesthetic expectations, bleaching treatmens are often sought, and the literature contains many studies on the effects of bleaching on composites. Our study aimed to examine the color stability of different types of composites immersed in different solutions after bleaching treatment.\u0000Methodology: A total of 72 samples (n = 8) of three composite materials were examined: Omnichroma (Tokuyama Dental Co., Tokyo, Japan), Estelite Posterior (Tokuyama Dental Co., Tokyo, Japan), and Quadrant (Cavex, Holland BV, Netherlands). All specimens were subjected to Total Blanc (Nova DFL, Rio de Janeiro, Brazil), which is an office-type bleaching agent. After bleaching treatments, the specimens were immersed in distilled water. The baseline measurements were then recorded. After being immersed in distilled water, tea, or coffee for seven days, the final color measurements were recorded. A VITA Easy Shade device (Vita Zahnarzt, Bad Säckingen, Germany) was used to take color measurements. The CIEDE2000 formula was used to calcuate ΔE00 values. The Kruskal–Wallis test was used to compare the ΔE00 values obtained from the composite samples to assess color stability. The results were rated at a significance level of p < 0.05.\u0000Results: After bleaching treatments, the interaction between the different composites and the solutions in which they were immersed had a statistically significant effect on ΔE00 values (p < 0.05). The highest mean value was obtained with the quadrant composite material that was immersed in the coffee solution.\u0000Conclusion: It is clear that tea and coffee cause discoloration in dental composites after bleaching treatments.
