Introduction: Cranberry (Vaccinium macrocarpon) is commonly consumed as a source of antioxidants. The cranberry juice has a sour and a little bit of bitter taste that can affect the salivary pH. The sour taste is a result of its high content of proanthocyanidin. Cranberry juice plays a role in maintaining oral and dental health. Cranberries’ flavonol and proanthocyanidin content play a role in preventing dental caries by preventing the growth of Streptococcus mutans. This study was aimed to compare the salivary pH before and after cranberry juice consumption. Methods: This research was quasi-experimental. The research population was the students from the Faculty of Dentistry Universitas Padjadjaran, and the sampling method was purposive sampling. Thirty-five male and female students with no history of systemic disease and drug administration, no orthodontics appliance and denture, were involved in this experiment. Students with lesions on oral mucosa were also excluded from this study. The pH measurement was performed with a digital pH meter to record the salivary pH ratio before and after consumption of cranberry juice. Before salivary pH comparison analysis was performed, the normality test was conducted, then the analysis was continued using the paired t-test. Statistical analysis was determined at α=0.05. Results: The average values of salivary pH ratio before and after consumption of cranberry juice were 6.714 and 7.246, respectively. The normality test showed that the p-value before and after consumption of cranberry juice were 0.143 and 0.285, respectively (p-value>0.05), which categorised in the normal distribution. The paired t-test statistical analysis showed the p-value of 0.001 (p-value<0.05), which considered as significant. This result indicated that there was a significant difference in the salivary pH before and after consumption of cranberry juice. Conclusion: The salivary pH is increasing after cranberry juice consumption.

Objectives: Marginal and internal fit of restorations are two important clinical factors for assessing the quality and durability of computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated monolithic zirconia restorations. The purpose of this study was to evaluate the marginal and internal fit of CAD/CAM zirconia crowns with two different scanners (i3D scanner and 3Shape D700). Materials and Methods: Twelve extracted sound human posterior teeth were prepared for full zirconia crowns. Two different extraoral scanners namely i3D scanner and 3Shape D700 were used to digitize type IV gypsum casts poured from impressions. The crowns were milled from presintered monolithic zirconia blocks by a 5-axis milling machine. The replica technique and MIP4 microscopic image analysis software were utilized to measure the marginal and internal fit by a stereomicroscope at ×40 magnification. The collected data were analyzed by paired t-test. Results: The mean marginal gap was 203.62 μm with 3Shape D700 scanner and 241.07 μm with i3D scanner. The mean internal gap was 192.30 μm with 3Shape D700 scanner and 196.06 μm with i3D scanner. The results of paired t-test indicated that there was a statistically significant difference between the two scanners in marginal fit (P=0.04); while, there was no statistically significant difference in internal fit (P=0.761). Conclusion: Within the limitations of this study, the results showed that type of extraoral scanner affected the marginal fit of CAD/CAM fabricated crowns; however, it did not have a significant effect on their internal fit.

Abstract: Mouthwash is one of the accessible oral healthcare and practical for use by the community. Various commercial products contain more than one active ingredient; the most common one is alcohol with varied concentrations from 6% to 26%. Mouthwash with high concentration of alcohol can cause some effects to some users, like burning and dry sensation of the oral mucosa. Dry oral mucosa caused by reduced saliva production will be more susceptible to irritation. Reduced amount of saliva also causes lower oral pH which leads to increased growth of cariogenic bacteria. This study was aimed to investigate the influence of alcoholic mouthwash to salivary flow and salivary pH. This was a quasi-experiment study with before and after treatment groups. The population study was students of Dental Medical Education Program of Medical Faculty of University of Sam Ratulangi, Manado, batch 2012, with a total of 30 respondents obtained by using purposive sampling method. The T test showed that salivary flow rate before and after treatment had no significant difference (p >0.05) based on T test. Moreover, the Wilcoxon test showed that there was no significant difference of salivary pH between before and after treatment (p >0.05). Conclusion: There was no effect of rinsing with alcoholic mouthwash on salivary flow and salivary pH.Keywords: alcoholic mouthwash, salivary flow rate, salivary pH Abstrak: Obat kumur merupakan salah satu produk perawatan kesehatan gigi dan mulut yang mudah diperoleh dan praktis digunakan sendiri oleh masyarakat.
