Saliva is the mixture of oral fluid, that has function to protect the oral cavity. Hormonal contraception is very popular in Indonesia to avoid pregnancy. This study aimed to evaluate salivary volume and pH of woman who taking contraceptive pill and by injection. The design of study was a cross sectional . The subjects were 30 women, 20-35 years old, with the approval of ethical clearance from Ethic Comittee Medical Faculty of Gadjah Mada University. The subjects were divided into 3 groups (taking contraceptive pill, by contraceptive injection and control) that each group consisted of 10 women. The criteria of subjects were healthy, no orthodontic treatment, no prothesa or crown, and taking hormonal contraception more than 3 months. Saliva samples were collected in the afternoon (16.00-18.00 pm) for 1 minute using unstimulating method. Data analysis using ANOVA test (p<0,05). The results showed that there were significant differences in salivary pH and volume. As conclusion, hormonal contraceptive can increase salivary pH and volume.

Different designs of ring clasp were indicated in short or long span bounded saddle. However, few researches have been done to calculate their retentive absolute forces. The purpose of this in-vitro study was to measure the retentive force of four different ring clasp designs. A test model was made from maxillary plastic replica. Second molar was seated in silicone mould then poured with dental stone. 24 cobalt-chromium ring clasp designs were fabricated to engage 0.5mm undercut using standard casting technique. They were examined radiographically for any casting defects. The dislodging force was measured for each clasp using universal testing machine. The results showed that ring clasp design 2 produced the highest retentive force, while, clasp 4 was the lowest among the other clasps. In addition, significant difference regarding the mean retentive force was estimated among designs 1, 2 and 4. The means of retentive force of ring 1, 2, 3, and 4 were equal to 17.40 Â±2.97, 17.52 Â±3.05, 12.35Â±0 .98, and 11.15Â±2.15 N, respectively. Modifying the ring clasp design by adding extra rest or fortification will change its retentive force using the same undercut depth. Each ring design provides definite retentive force. As conclusion, each ring clasps design offered specific retentive force in dry environ-ment. However design 2 presented the highest force rate while design 4 was the least retentive.

Nano tooth coloured materials may have been produced as an ideal restorative material, however, thermally induced stresses may lead to microleakage between restorative material and tooth structure which may cause unwanted complications. Thermocycling has been an important method to emulate the thermal changes of the oral cavity. This study was aimed to investigate the effect of increasing number of thermal cycles on marginal leakage of nano tooth coloured materials. A total of 56 Class V cavities was prepared on the buccal surface of the extracted single rooted human premolars and restored with either Filtek Z350 (3M-ESPE, USA) or Ceram X (Dentsply, Germany). The samples were then divided into four groups with (n=7): 1) 0 thermocycle, 2) 500 cycles, 3) 5,000 cycles and 4)10,000 cycles. All samples were immersed in 2% methylene blue dye for 4 hours at room temperature, sectioned and viewed under stereomicroscope for dye penetration. Data were analyzed using T-test and One-way ANOVA and Post-hoc Scheffe with p<0.05 considered to be significant. Microleakage was only evident in both materials at 5,000 cycles above. The results showed that there was a significant difference in microleakage between 5,000 and 10,000 cycles for both materials (Filtek Z350: p<0.001; Ceram X: p<0.001). However, there was no significant difference in microleakage between Filtek Z350 and Ceram X at 5000 cycles (p=0.194) and at 10,000 cycles (p=0.499). As conclusion, microleakage increases with the duration of thermal cycling in both nano-tooth coloured materials. Both materials showed similar pattern of microleakage when challenged to a higher number of thermal cycles.

Alcohol is used as beverage with various purposes. Drinking alcohol is supposed to be able to distress central nerve system. Saliva production is controlled by both symphatic and parasymphatic nerves. This design of study was a cross sectional. This study aimed to evaluate the effect of alcoholic drink on salivary acidity (pH) and volume. The subjects were 30 males, aged 15-35 years old, with the approval of ethical clearance from Ethic Comittee Medical Faculty of Yogyakarta Muhammadiyah University, Yogyakarta. The subjects were divided into 2 groups (alcoholic and non-alcoholic drink as control) with 15 persons, respectively. Saliva sample was collected at night. In alcoholic group, saliva was collected for 60 minutes after drinking alcohol. The subjects were instructed to gargle mineral water for 1 minute, then they were asked to stand and let the saliva flow for 3 minutes into saliva-collecting pot. Data analysis of salivary volume and pH using unpaired t-test (p<0,05). The results showed that there were significant differences in salivary volume and acidity (pH) between alcoholic and non alcoholic drink. In conclusion, drinking alcohol can decrease salivary volume and pH.

Retentive force may be increased in deeper undercuts. Three clasps were examined for this hypothesis in order to analyze the retentive force change properties for each clasp design with increasing undercut depth only. A total of 36 cobalt-chromium clasps, using half-round pattern and standard casting technique were fabricated. Three groups of clasps; Rest-Plate-Akers system, half-half, and Akers were engaged in 3 increasing undercut depths (0.25, 0.35, and 0.5 mm) on natural premolars. The test model was stone duplicate of plastic replica. Clasp retentive force was measured using universal testing machine. The results showed that the retentive forces for the tested undercuts (0.25, 0.35 and 0.5mm) were 8.59Â±1.89, 14.74Â±2.70 and 15.21Â±1.17 N for Akers; 3.06Â±0.88, 4.26Â±0.29, and 5.9Â±0.53 for half-half; and 0.9Â±0.15, 2.06Â±0.60, 2.3Â±0.50 N for Rest-Plat-Akers system respectively. Besides, the retentive force for each clasp design increased in a different way with each incremental augmentation of undercut depth. As a conclusion, changing the undercut depth altered the retentive force of the used clasp. Therefore, a clasp chosen for a definite undercut depth also can be used for deeper undercut on the same abutment when higher retentive force is required with respect to the other indication criteria.

Preclinical session is one way of training dental undergraduates to prepare teeth for restorations. The aims of the study were to evaluate studentsâ€™ perception and satisfactory level in preparing tooth for porcelain fused to metal crown in preclinical fixed prosthodontics sessions. A total of 104 fourth year dental undergraduates students participated in this study. Lecture consisted of the diagrams of step-by-step procedure in preparing porcelain fused to metal crown on tooth 24. Video demonstration was also conducted. After they were satisfied with the preparation, they were asked to answer a series of multiple choice questions on their performance. Only 92 students completed the questionnaire. Majority of the students taught that their occlusal and axial reductions were about right. As for the margin, 50 students claimed that the margin was located on gingival margin while 88 students said that they prepared shoulder margin buccally and 4 students created chamfer margin buccally. Seventy four out of 92 students were slightly satisfied with their crown preparations. Twenty five students said that they were very competent and confident in doing crown preparation to patients. Almost all fourth year dental students could perform porcelain-fused-to-metal crown preparation with confidence. As conclusion, exposure to our teaching methods and aids appears to help them in preparing these tasks.
