Objective: Chemotherapeutic drugs not only have a therapeutic effect, but also cause serious damage to healthy organs. In this study, we investigated on the possible efficacy of propolis (PS) on the sublingual gland tissues exposed to 6-mercaptopurine (6MR) in male rats. Materials and Methods: Twenty-eight Wistar albino rats were allocated to four groups: control (KON), PS, 6MR, 6MR+PS. At 12 days of trial, sublingual glands of all rats were immediately dissected and analysed using the stereological technique and histological examination. Results: Our findings revealed a significant increase in the total volume of stroma and significant decrease in the total volume of the total volumes of mucous acini, straited ducts, interlobular ducts, and intralobular ducts in the 6MR group than the KON group (p<0.05). A significant decrease was also found in the mucous cell number and the serous cell number in the 6MR group than the KON group (p<0.05). In the 6MR+PS group, we observed that the total volume of stroma, as well as the mucous cell number and the serous cell number were increased compared to the 6MR group (p<0.05). Besides, the total volumes of mucous acini, straited ducts, interlobular ducts, and intralobular ducts were significantly increased in the 6MR+PS group than the 6MR group (p<0.05). Conclusion: Our results showed that 6MR treatment caused toxicity in sublingual gland tissues, as well as PS application improved such changes in sublingual glands exposed to 6MR.

Objective: The purpose of this study is to evaluate possible mineral losses in mandibular first premolars after the use of twin-block appliance, by enamel microhardness measurement method. Materials and Methods: Twenty patients (12 females, 8 males; mean age=12.21±1.12) indicated as fixed orthodontic treatment with mandibular first premolar extraction after functional treatment with twin-block were included in the study. The twin-block appliance was used continuously (excluding meals) for 12 months. The appliance used in this research, which is a split-mouth study, was designed to cover the first premolar only on one side of the mandible, leaving the opposite the first premolar tooth exposed. After the extraction of the mandibular first premolars, two groups were formed: the teeth outside the appliance (Group I) and the teeth inside the appliance (Group II). Hardness measurements were calculated using Vicker’s microhardness measuring device on the buccal and lingual regions of the both groups. 200 g load was applied to specimens for 10 sec. Two Independent Sample t test used in the statistical analysis of the data. Results: A statistically significant difference was found between the hardness values of the buccal and lingual tooth regions of Group I and Group II (p <0.05). Group II showed statistically significantly lower hardness values on both tooth regions (buccal region and lingual region) than Group I. In both groups, the hardness values on the buccal regions of the teeth were found to be significantly lower than the hardness values on the lingual regions (p <0.05). Conclusion: There is a possibility of mineral loss in the teeth remaining inside the appliance in treatments using the twin-block appliance

Objective. This study investigated the effect of air-abrasion and erbium:yttrium-aluminum-garnet (Er:YAG) laser treatments on push-out bond strength (PBS) between hard relining material and metal housing of an overdenture attachment system. Material and Methods. A total of 36 metal housings were randomly divided into 3 subgroups according to surface pretreatments (n=12): Control (no surface treatment; C), air-abrasion (A), and Er:YAG laser (L). Surface roughness (Ra) of specimens was determined using a profilometer. One additional specimen per group was evaluated by scanning electron microscopy (SEM). The hard relining material was bonded to metal housings, and a PBS test was performed using a universal testing machine. Data were statistically analyzed using 1-way analysis of variance (ANOVA), Tukey’s honestly significant difference (HSD), and Tamhane’s T2 tests (α=.05). Results. C and L groups showed the lowest and highest Ra values, respectively. The mean Ra of the A group was statistically different from the mean values of the C and L groups (P<.001). The L group showed higher PBS values than the C group (P<.05), whereas the A group exhibited statistically similar PBS values to both C and L groups (P>.05). Conclusions. Air-abrasion did not significantly increase the bond strength between the metal housing and hard relining material. Er:YAG laser irradiation noticeably improved the PBS but caused surface microcracks.
研究目的本研究探讨了气磨和铒钇铝石榴石（Er:YAG）激光处理对覆盖义齿连接系统的硬衬垫材料和金属外壳之间的推出粘接强度（PBS）的影响。根据表面预处理情况，将 36 个金属外壳随机分为 3 个亚组（n=12）：对照组（无表面处理；C）、气磨组（A）和 Er:YAG 激光组（L）。使用轮廓仪测定试样的表面粗糙度（Ra）。每组还有一个试样通过扫描电子显微镜（SEM）进行评估。将硬衬垫材料粘合到金属外壳上，并使用万能试验机进行 PBS 测试。采用单因素方差分析（ANOVA）、Tukey 诚实显著性差异（HSD）和 Tamhane T2 检验（α=.05）对数据进行统计分析。C 组和 L 组的 Ra 值分别最低和最高。A 组的平均 Ra 值与 C 组和 L 组的平均值存在统计学差异（P.05）。结论。空气磨蚀并没有明显提高金属外壳和硬衬垫材料之间的粘结强度。Er:YAG 激光照射能明显改善 PBS，但会造成表面微裂纹。
