Abstract

ABSTRACTIntroduction: One of the identification methods in forensic odontology is to estimate age through tooth characteristics. With age, odontoblast cells that line the pulp cavity will continue the process of secondary dentin deposition at a lower rate. Generally, maxillary canines are teeth that can survive in the oral cavity until old age and are less likely to wear out. This study aimed to determine the correlation between human chronological age and the dentin volume of the maxillary canines using CBCT radiographs. Methods: An analytic study of the Pearson correlation test was conducted on 114 samples of CBCT radiographs of the maxillary canines from the Radiology Unit of the Rumah Sakit Gigi dan Mulut, Faculty of Dentistry, Universitas Padjadjaran. The inclusion criteria for this study were canines with closed apex, no caries, no attrition, no restorations, no orthodontic treatment, and generally good health. Maxillary canine dentin volume was measured using the application ITK-SNAP version 3.8.0. The results of dentin volume were analyzed using the Pearson correlation test using SPSS IBM Statistics 25. Results: Pearson correlation analysis showed the correlation coefficient value (r= 0.270 and (r = 0.427) for the male and female samples, respectively. Conclusion: The correlation between chronological age and maxillary canine dentin volume in this study was not strong enough to be used as a single parameter in the age estimation method. Future research is expected to expand the sample size with a homogenous age distribution to obtain more consistent and accurate results.Keywords: age estimation; dentin volume; maxillary canines; ITK-SNAP; CBCT.

Abstract

Histopathological examination plays an important role in assisting the diagnosis of disease. One indispensable ingredient is a liquid fixation. fixation is a critical step in the preparation of histological section by which body tissue immersed in fixation liquid and preserved from decay thereby preventing autolysis and putrefaction. The aim of this study is to determine the better fixation in between bouin liquid and buffer formalin. The study was an experimental laboratory of two rats. A rat is injected fluids Bouin, others injected buffer formalin. The rats liver is taken and immersed into a fluid according to the injection of a liquid fixation. The rats liver was histologically prepared with hematoxylin eosin staining. The assessment by microscopically examination at 450X magnification. As an indicator seen from the changes in the nucleus of the cell, if there is a cell necrosis (bad) and normal cells (good). The study result shows that Bouin liquid got more normal cells (84.61%), while buffer formalin (38.46%). In conclusion, bouin liquid better than buffer formalinKeywords: fixation, liquid bouin, buffer formalin

Abstract

Introduction: Exfoliative cheilitis (EC) is one of the most common cheilitis found in the community. This lesion can cause difficulty in mouth opening, speech difficulties, and reduced aesthetical value of the lips. EC is a chronic inflammation characterised by desquamation, erythema, and crusting on the upper or lower lip. This study evaluated severity level, stress, and bad habit among dental students with exfoliative cheilitis. Methods: The method used in this research was descriptive with a total sampling method on the populations of dental students batch of 2016 to 2018 of the Faculty of Dentistry Universitas Padjadjaran, which obtained 83 dental students with EC. The lips were then examined, and data was recorded. EC was classified into three stages in clinical manifestation: mild, moderate, and severe exfoliative cheilitis. The data were presented with a simple frequency distribution table. Result: 30.1% of the research subjects had mild EC, 53% had moderate EC, and 16.9% had severe EC. The predisposing factors of EC in this research were stress and bad habits, where the percentage contribution were 53% and 16.9%, respectively. Students were also found with both stress and bad habits with a percentage contribution of 30.1%. Conclusions: Moderate exfoliative cheilitis is most commonly found with desquamation and erythema clinical features. The predisposing factor of exfoliative cheilitis is stress which has the highest percentage among dental students.

Abstract

Introduction: Enamel print pattern is a series of lines representing the enamel rod ends pattern. These lines are seen running in varying directions creating distinct sub-patterns; thus, enamel print pattern allows for personal identification. This study was aimed to investigate the enamel print pattern in Deutero-Malay sub race based on extracted female permanent maxillary central incisors. Methods: This study used descriptive-analytic methods. The population of this study was Deutero-Malay sub-race female individuals who came to Batu Pahat Dental Surgery, Johor, Malaysia. The samples were 31 post-extracted permanent maxillary central incisors teeth in good condition, with closed root apex. Photomicrographs and a digital photo of samples were taken, then analysed using SourceAFIS-1.7.0 biometric software. Results: The results showed that there was a combination of few sub-patterns. The most prominent sub-pattern was linear-branched (21.36%), in decreasing orders of prominence were the wavy-branched (19.42%), wavy-unbranched (16.50%) and linear-unbranched (15.53%). The less common sub-patterns were the whorl-open (9.71%), loop (6.80%), whorl-closed (5.83%) and stem-like (4.85%). Conclusion: The enamel print pattern in every central incisor has no similarity; hence can be a possible tool for personal identification.

Abstract

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.
