Objective: Dental caries is one of the most common microbial diseases. Because of the infectious nature of the disease, the immunologic response by the host plays an essential role in its development. Therefore, the aim of this study was to evaluate the sCD14 levels in patients exhibiting two to three teeth with caries involving pulp along with apical periodontitis requiring root canal treatment. Material and Methods: This study was carried out on 20 participants, of whom 10 were caries-free (Control) and 10 had two to three teeth with symptomatic irreversible pulpitis along with apical periodontitis requiring root canal treatment, within the ages of 20- 30 years. Unstimulated saliva of the participants was collected with disposable needle-less syringe from buccal and labial vestibules. The sCD14 levels in salivary samples were assessed before and following endodontic treatment. The results were analyzed by ELISA. Results: The obtained levels of sCD14 were analyzed statistically. Paired T test was performed to assess the significance. The results revealed that there was a significant difference in sCD14 levels with a P=0.0005, as it had drastically reduced once the inflammation has subsided. Conclusion: Higher values of sCD14 levels were seen in patients with symptomatic irreversible pulpitis along with apical periodontitis than in caries free group. The study also showed that sCD levels were significantly reduced following post endodontic treatment. Therefore, increased levels of sCD14 can be considered as a marker of inflammation.

Objective: Smoking is among the most destructive habits which have numerous effects on the body.The chemical components of cigarettes destroy the anti-oxidant content of the saliva.In this study, the concentration of albumin and uric acid of healthy non-smokers and smokers was measured based on the frequency of smoking. Material and Methods:In this cross-sectional study, 26 heavy smokers, 27 normal smokers, and 29 non-smokers between the ages of 25 to 40 were selected.The subjects did not suffer from any systemic or periodontal conditions. Unstimulated saliva was collected by spitting. The level of salivary albumin was measured by Bromocresol Green, and the level of salivary uric acid was measured by the uricase method.The selected method of analysis, using SPSS software, was One-Way ANOVA. Results: Mean albumin content of saliva was 33.52 ± 1.52 mg/dl in non-smokers and 23.88 ± 8.93 mg/dl in heavy smokers.The mean uric acid concentration in non-smokers was 2.98 ± 0.79 μmol/L and in heavy smokers was 2.32 ± 0.77 mg/dL.The differences between levels of both salivary uric acid and salivary albumin were significant in heavy smokers and non-smokers(P=0.001). Conclusion: Based on the findings of this study, saliva concentrations of both Albumin and Uric Acid change based on the frequency of smoking.Decreased level of salivary albumin and decreased level of salivary uric acid can be considered as markers of the harmful effects of smoking on oral health.

Objective : The current study aimed to evaluate the effect of diode laser irradiation (980 nm) and warm air drying (50°C) on shear bond strength between Lithium di-silicate (IPS e.max; Ivoclar) and human dentin using both (Etch & Rinse) adhesive, Adper™ Single Bond 2 (3M ESPE) and (Self-etch) adhesive, Single Bond Universal TM (3M ESPE) before adhesive polymerization. Material and Methods : 54 sound lower molars were sectioned to obtain flat dentinal surfaces. Specimens were divided into 2 equal groups (n=27): Group 1 (ER) and Group 2 (SE) according to bonding approach. Each subgroup was subdivided according to dentin surface treatment into 3 equal subgroups (n=9): Control (Co), Diode laser irradiation (L) and Warm air drying (W). All specimens were adhesively cemented to IPS e.max® CAD discs using RelyX™ Ultimate Clicker™(3M ESPE) resin cement. Samples were then subjected to pre-loading in a thermodynamic manner. All samples were tested for shear bond strength using computer-controlled material testing machine. Data analysis was performed using two-way (ANOVA) (p< 0.05) followed by pair-wise Tukey’s post-hoc tests. Results: In (SE) group, the subgroup (W) had the highest shear bond strength values followed by (Co) subgroup and the least was (L) subgroup with statistically significant difference. As for (ER) group, the subgroup (W) had the highest shear bond strength values followed by (Co) subgroup and the least was (L) subgroup with no statistically significant difference. Conclusion: Warm air drying for (SE) bonding approach increased shear bond strength of Lithium di-silicate to human dentin and can be introduced as a new effective protocol.
目的:研究半导体激光辐照(980 nm)和热风干燥(50℃)对二硅酸锂(IPS e.max;Ivoclar)和人类牙本质使用(Etch & Rinse)粘合剂，Adper™Single Bond 2 (3M ESPE)和(Self-etch)粘合剂，Single Bond Universal TM (3M ESPE)在粘合剂聚合之前。材料与方法:对54颗正常下磨牙进行切面，获得平整的牙基面。按粘接方式将标本分为2组(n=27): 1组(ER)和2组(SE)。每个亚组根据牙本质表面处理分为3个相同的亚组(n=9):对照组(Co)，二极管激光照射组(L)和热风干燥组(W)。所有标本均使用RelyX™Ultimate Clicker™(3M ESPE)树脂胶粘剂与IPS e.max®CAD椎间盘进行粘接。然后以热力学方式对样品进行预加载。所有样品均使用计算机控制的材料试验机进行剪切粘结强度测试。采用双因素方差分析(ANOVA) (p< 0.05)进行数据分析，随后采用双因素Tukey’s事后检验。结果:在(SE)组中，亚组(W)剪切强度值最高，其次是(Co)亚组，最小的是(L)亚组，差异有统计学意义。在(ER)组中，(W)亚组剪切强度值最高，(Co)亚组次之，(L)亚组最小，差异无统计学意义。结论:热风干燥(SE)粘接方法可提高二硅酸锂与牙本质的剪切粘接强度，是一种新的有效粘接方法。

Objective: The aim was to evaluate the influence of fluoride-releasing restorative materials in enamel and dentin microhardness. Material and Methods: 40 blocks (5x5x3 mm) from cervical third of human molars received a cavity preparation between the enamel and dentin, and the restorations were subjected to in vitro caries model. Specimens were randomly restored with (n=10): conventional glass ionomer cement (Ketac Cem, 3M ESPE); polyacid-modified composite resin (Ionoseal, VOCO); resin-modified glass ionomer cement (Ionofast, Biodinâmica); or microhybrid composite resin (Filtek Z250, 3M ESPE). The specimens were sectioned longitudinally and enamel and dentin Knoop microhardness were determined at different distances from the restorative material (100, 200 and 300 μm) and depth of surface (20, 40 and 60 μm). The data were submitted to three-way repeated measures ANOVA and Tukey ́s test (α=0.05). Results: For enamel, the double interactions between material x distance and material x depth were statistically significant. In all depths and distances, the highest values of enamel microhardness were observed for Ketac Cem. In dentin, the materials differed statistically from each other, and Ionoseal obtained higher microhardness values than those found in Ionofast. Conclusion: Conventional glass ionomer cement is more effective in preventing enamel demineralization around restoration followed by the polyacid-modified composite resin. In dentin, the polyacid-modified composite resin obtained better performance than resin-modified glass ionomer cement.

Department of Biostatistics. Istanbul, Turkey. ABSTRACT Objective: This cross-sectional study aimed to assess level of DA among dental students in different grades and patients and to evaluate associations between DA and presence of dental caries. Material and Methods: Both four hundred all-grade dental students of Istanbul University and patients of Istanbul University Hospital were included in the study after random selection. Data regarding gender, oral hygiene habits, frequency of dental visits, and educational level were obtained via questionnaire. DA of participants were measured using both Modified Dental Anxiety Scale (MDAS) and Dental Fear Survey (DFS). The prevalence of caries was determined using International Caries Detection and Assessment System Criteria (ICDAS). Data were analyzed using Kruskal-Wallis, Mann-Whitney U and Chi square tests. Results: Female patients and female 4th-year students had significantly higher MDAS scores (p<0.05). First-year students had significantly higher MDAS and DFS scores than 4th and 5th-year students (p<0.05). Patients who had caries and brushed their teeth less than twice a day had significantly higher MDAS scores (p<0.05). Among 3rd-year students, individuals who visited dentist regularly had lower MDAS scores (p<0.05). Conclusion: DA among senior dental students was lower than that in younger students with an increase in knowledge about dentistry.
