Background: Accumulation of denture plaque can lead to pathological changes in oral mucosa, such as denture stomatitis, halitosis, and caries. Plaque matrix is mostly formed by protein (30%) and polysaccharide complexes. Thus, an alternative enzyme solution as denture cleanser is required for hydrolysis of denture plaque. Papain is a proteolytic enzyme hydrolyzing proteins, while β-1,3-glucanase is a hydrolase enzyme hydrolyzing polysaccharides. Purpose: This study aimed to analyze the differences of effectiveness of ß-1,3- glucanase Vigna unguiculata enzyme and papain Carica papaya enzyme in hydrolysis of denture plaque. Method: This research was a laboratory experimental research with post test only control group design. After using denture for 24 hours, the denture was soaked in a solution of 100 ml PBS, papain enzyme, and β 1-3 glucanase enzyme at a concentration of 0.5 mg/ml, 1 mg/ml, and 2 mg/ml for 10 minutes. The solution from plaque hydrolysis was soaked in PBS and vortex enzyme for 2 minutes, then soaked in ice water for 15 minutes, and centrifuged at 3000 rpm 5-10º for 10 minutes. The supernatant was separated and analyzed. Turbidity readings then were performed in spectrofotometer with a wavelength of 480 nm. Result: 2 mg/ml of ß-1,3 glucanase enzyme generated the highest values of hydrolysis with a mean percentage of 68.77% compared to papain enzyme (44.86 %). The lowest values of hydrolysis weregenerated by PBS with a mean percentage of 3.24%. Conclusion: ß-1,3-glucanase enzyme is more effective in hydrolysis of denture plaque than papain enzyme.

Background: Fixed orthodontic appliance patients have a high risk to increasing plaque accumulation in tooth surface due to the presence of fixed appliance components. Using mouthwash with antibacterial agent from herbal material can control dental plaque accumulation. Bay leaf (BL) contains active compounds such as essential oil, tannin and flavonoid that have been known as an antibacterial agent. Purpose: The purpose of this study was to determine the effect of rinsing with 60% of BL aqueous decoction to the accumulation of dental plaque in fixed orthodontic appliance patients. Method: This research was an experimental clinical research with pretest and post-test control group design conducted on 20 subjects with age ranged between 18-25 years old. All subjects were undergoing the last stage (finishing) of fixed active orthodontic treatment. The subjects were instructed to rinse with 60% of BL aqueous decoction and 0.2% chlorhexidine as a control. Wash out period that needed between rinsing with 60% of BL aqueous decoction and rinsing with 0.2% chlorhexidine was 7 days. Each mouthwash used routinely for 7 days with same duration and intensity. Plaque scoring was measured before and after each treatment using Orthodontic Plaque Index (OPI). Result: One-way Anova test showed that there was a significant difference in the plaque index before and after treatment between the group of rinsing with 60% of BL aqueous decoction and group of rinsing with chlorhexidine (p<0.05). Conclusion: Rinsing with 60% BL aqueous decoction can decrease the accumulation of dental plaque in fixed orthodontic appliance patients.

Background: Gender determination is an important aspect of the identification process. The tooth represents a part of the human body that indicates the nature of sexual dimorphism. Artificial intelligence enables computers to perform to the same standard the same tasks as those carried out by humans. Several methods of classification exist within an artificial intelligence approach to identifying sexual dimorphism in canines. Purpose: This study aimed to quantify the respective accuracy of the Naive Bayes, decision tree, and multi-layer perceptron (MLP) methods in identifying sexual dimorphism in canines. Methods: A sample of results derived from 100 measurements of the diameter of mesiodistal, buccolingual, and diagonal upper and lower canine jaw models of both genders were entered into an application computer program that implements the algorithm (MLP). The analytical process was conducted by the program to obtain a classification model with testing being subsequently carried out in order to obtain 50 new measurement results, 25 each for males and females. A comparative analysis was conducted on the program-generated information. Results: The accuracy rate of the Naive Bayes method was 82%, while that of the decision tree and MLP amounted to 84%. The MLP method had an absolute error value lower than that of its decision tree counterpart. Conclusion: The use of artificial intelligence methods produced a highly accurate identification process relating to the gender determination of canine teeth. The most appropriate method was the MLP with an accuracy rate of 84%.

Background: The difficulty of determining chronological age is increased in individuals with conditions that may affect normal development. Some systemic conditions in children, for example Down syndrome, may cause abnormal physiological maturation. Skeletal and dental age are considered the most apt physiological age indicators in determining chronological age. Purpose: This study aimed to compare and analyze the relationship between two developmental parameters (dental history and skeletal age) as indicators of the chronological age of children with Down syndrome. Methods: The study design was cross-sectional with a paired t-test to analyze the differences in chronological and dental age of the samples. The radiograph selection was based on purposive sampling. The study material consisted of 30 panoramic radiographs and lateral cephalometrics of 6-14 years old children with Down syndrome and those experiencing normal development (control group) divided into two groups of 15 subjects who attended the Pediatric Dentistry Polyclinic, RSGM, Universitas Padjadjaran. Statistical analysis employed a t-test to determine the difference between chronological and dental age, while a Spearman rank correlation was used to evaluate the correlation between dental and skeletal age. Results: The results showed there to be no statistical difference between chronological and dental age, where p > 0.05, but a significant relationship between dental and skeletal age in children diagnosed with Down syndrome, where p = 0.05. Conclusion: It is concluded that dental age identified by means of the Nolla method is closer to chronological age than skeletal age using the cervical vertebrae maturation method.

Background: Squamous cell carcinoma is a malignancy of oral cavity mostly occurred and can also metastasize. p53 gene is a tumor suppressor gene that plays an important role in carcinogenesis. The role of wild-type p53 is very important in suppressing the formation of a malignancy. p53 also has many other important functions. p53 is a suppressor of tumor/ cancer progression through the response of cell cycle to DNA damage and by giving time to repair DNA prior to replication of genes. p53 mutation, mostly occurs in a malignancy, so earlier histopathological transformation can be detected by observing p53 mutation. The prognosis of squamous cell carcinoma in oral cavity, therefore, depends on histopathological grading and clinical staging of the tumor. To enforce the histopathological grading, in addition based on histopathology differentiation, the earlier histopathological transformation can also be assessed. Purpose: This study aimed to determine the correlation of p53 expressions and histopathological grading in oral cavity squamous cell carcinoma. Method: This study was a retrospective study on 20 cases of oral cavity squamous cell carcinoma examined at Department of Pathology Anatomy in Hasan Sadikin Hospital in Bandung. Immunohistochemical examination was then performed using p53 antibodies to determine the correlation of p53 expression and histopathological grading in oral cavity squamous cell carcinoma to predict prognosis. Result: The overall results showed that there was no correlation between p53 expression and histopathological grading in oral cavity squamous cell carcinoma of the oral cavity although there was a very strong correlation between p53 expression and histopathological grading I (p<0.01). Conclusion: It can be concluded that there was no correlation between p53 expression and histopathological grading in oral cavity squamous cell carcinoma. Thus, p53 expression cannot be used to predict a prognosis.

Background: Herpes labialis is a form of secondary or recurrence of primary herpes simplex infection. Herpes simplex virus is latent. It can reactivate due to reactivation of the virus induced by emotional stress, high fever, ultraviolet exposed, oral mucosal or nerve tissue trauma, immunosuppression condition, and hormonal disorders. Purpose: The study aimed to report the management of patients with herpes labialis on the lower lip triggered by emotional stress. Case: A 58 year-old woman complained of pain in her lower lip. The patient had suffered from the pain since one month ago. The patient had been treated with a lip ointment, triamcinolone acetonid 0.1% (Kenalog®), for 2 weeks, but became thick, dry, and worse. She said that she got many calamities related to her family, leading to the increased busyness and psychologically distressed conditions. Extra oral examination of the lower lip showed erythematous erosion sized 4x4 mm, yellowish red crusting sized 3x4 mm, and translucent multiple vesicles sized 1x1 mm with well circumscribed as well as irregular edges. On palpation submandibular lymph nodes, dextra and sinistra were palpable, rubbery, mobile and painless. Based on intra-oral examination, however, there were no abnormalities. Case management: The diagnosis was determined based on anamnesis, clinical examinations, and supporting examination of Ig M and anti HSV-1 Ig G. The patient then was prescribed systemic and topical Acyclovir. Conclusion: Some laboratory tests are necessary to confirm the diagnosis and determine the accurate therapy of herpes labialis in addition to the history and clinical features.

Background: The most common fungal infection found in oral cavity is oral candidiasis, largely caused by Candida species, particularly Candida albicans (C. albicans). Candida infection can get worse since it is difficult to be treated and resistant with antifungal drugs. Therefore, new drugs and compounds as well as alternative therapies involving natural sources that have antifungal activities have continually been developed. Limonene, β-pinene, and ɣ-terpinene contained in Citrus limon essential oil have been known to have quite good antifungal activities against C. albicans. Purpose: This research aimed to examine and analyze the effects of Citrus limon essential oil on cytomorphometric changes of C. albicans. Method: The research used post test only control group design. Based on the results of the pre-elementary research on antifungal activities of Citrus limon essential oil against C. albicans, Citrus limon essential oil used in this research was on concentrations of 1.56%, 1.37%, 1.17%, 0.98%, and 0.78%. Citrus limon essential oil by C. albicans inoculum and incubated for 24 hours and 48 hours. After the incubation, those C. albicans cells were fixed, dried, and then observed using a scanning electron microscopy. Result: The most effective concentrations of Citrus limon essential oil triggering cytomorphometric changes of Candida albicans were at 1.37% and 1.56% with the incubation period of 48 hours. Conclusion: C. albicans can undergo necrosis process through cytomorphometric changes after the administration of Citrus limon essential oil at concentrations of 1.56% and 1.37% with the incubation period of 48 hours.

Background: Traumatic ulcers in patients with diabetes mellitus may experience delayed healing despite their diabetic condition being controlled. Liquid smoke coconut shell containing phenolic compounds can potentially accelerate the healing process. One healing process indicator is the increased number of fibroblasts, another being the increased amount of collagen. Purpose: This study aimed to analyze the amount of collagen in traumatic ulcers in diabetics after application of liquid smoke coconut shell. Methods: Alloxan was induced in twenty-four male Wistar rats as models of diabetes mellitus. A traumatic 10 mm ulcer was made along the labial fornix incisive inferior with a round, stainless steel blade before liquid smoke coconut shell and benzydamine hydrochloride (as the control) was administrated once a day. A biopsy of the labial fornix incisive inferior was subsequently performed after the topical application for 5 and 7 days. Histological assessment was conducted to analyze the amount of collagen by means of Masson Trichome staining. Results: Histologically, the topical application of liquid smoke coconut shell for 5 days significantly increased the amount of collagen, higher than that of benzydamine hydrochloride as the control (p=0.006) (p<0.05). Meanwhile, the topical application of liquid smoke coconut shell for 7 days made the concentration of collagen no significantly different from that of benzydamine hydrochloride as the control (p=0.156) (p>0.05). Conclusion: Liquid smoke coconut shell applied for 5 days increase the amount of collagen in traumatic ulcers in diabetic patients.
