Abstract

The purposes of this study are to study the pathogenesis of oral cancer and to see the role play of oncogenes, onco-suppressor genes in cancer growth and their mutation type. There are many predisposing factors which may influence the development of cancer. The factors are divided intrinsic (hereditary) and extrinsic factors (bacteria, viruses, fungi, chemical, drugs, radiation, trauma, heat, cold and nutrition). These agents may act individually, in combination with other carcinogen (co-carcinogen) or in combination with other agents that do not in themselves causes cancer (promoters), but that help the carcinogens to mutate or depress cells, but in the mechanism still enigma. Oncogenes onco-suppressor genes are normal genes in human. Oncogenes functions are as growth factor (e.g. sis), growth factor receptor (e.g. erbB1), signal transducer (e.g. ras) or nuclear factor (e.g. myc, jun). Tumor (oral cancer) will be arises if oncogenes and onco-suppressor genes function are disturbed by some carcinogen and these genes have mutation, deletion, amplification or translocation. That was also related to the loss or inactivation of onco-suppressor genes such as p53, so that causes the loss of the normal growth regulation/strait control that associated with tumorigenesis.   Keywords: oncogenes, onco-suppressor genes, pathogenesis, carcinoma

Abstract

Gingivitis is a form of periodontal disease most common in the community. Gingivitis is caused by bacteria in subgingival plaque, one of them is Porphyromonas gingivalis. Curcumin is a phenolic yellow pigment obtained from the powdered rhizome of Curcuma sp. which has anti-inflammatory effects. Curcumin can reduce the number and responses of cytotoxic T lymphocyte by signing on IL-1, IL-2, IL-12, and TNF. Variables observed in this study is the number and response of cytotoxic T lymphocyte in male Wistar rats gingiva. 16 male Wistar rats were divided into two groups: control and treatment groups. To cause gingivitis rats were injected with bacteria P. gingivalis 3x108 CFU concentrations as much as 0.02 ml of the gingival sulcus maxillary left for 2 days. The control group was given PBS and treatment group was given curcumin dose of 0.03 mg / g BW in intragastric starting from day 2 after induction of P. gingivalis. Rats sacrificed on day 3 (72 hours after the induction of P. gingivalis) and day 5, followed by extraction, fixation, tissue processing to be preparations with HE staining and IHC. Observation of the results carried out using a light microscope. Results showed that there was no cytotoxic T lymphocytes in the control and treatment groups, but in HE staining found existence of lymphocytes guess is that memory T lymphocytes (CD45). The conclusion of this study is in IHC staining method there is no difference in the number of cytotoxic T lymphocytes in the control group and the treatment, but in HE staining found existence of lymphocytes guess is that memory T lymphocytes, and the clinical features are redness and swelling until day 3 which the gingival more redness in the control group compared to the treatment group and healing has occurred on day 4 to day 5 in the control and treatment groups.

Abstract

Background: It is known that oral squamous epithelial dysplasia (SED) and carcinoma in-situ (CIS) are precancerous lesion and it could transform to squamous cell carcinoma (SCC). We had reported p53-Protein Over-Expression and Gene Mutational of Oral CIS, such as basaloid, verrucous, and acanthothic/atrophic types, but demarcated between SED to CIS and CIS to SCC and how their transformation is still unclear. It is considered that their molecular behavior related one another. Purpose: To understand the molecular behavior of them we examined p53 exon 5-8 gene mutation and their protein expression in the sequential cases. Methods: Using 10 cases formalin–fixed paraffin sections that composed SED appearance, CIS and SCC in the same case were subjected to P53 immunohistochemistry. Then all cases were subjected to p53 gene mutations analysis. By laser capturing microdissection dysplasia part, CIS part and SCC part were cutted, and followed by direct sequencing of PCR product for exon 5-8. Result: SED p53-protein over-expression in some cells, and the expression was increased to CIS and SCC. Mutational analysis for p53 gene showed that 60% of p53 gene mutation in CIS also found in SCC, therefore SCC had additional mutation in other exon of p53 gene. While no particular mutations were found in SED part of all cases. Conclusion: Carcinoma in-situ is a squamous cell carcinoma eventhough not invasive yet, but squamous epithelial dysplasia is an early step to malignancy. It needs other genes examination to know any genes are involved in the precancerous to cancer transformation process.

Abstract

We had been reported histological types of oral carcinoma in-situ (oral CIS), such as basaloid, verrucous, and acanthothic/ atrophic types. We considered that they have different histological appearance influenced by molecular behavior. To understand the molecular behavior of them we examined p53 exon 4–8 gene mutation and their protein expression. Using 35 cases formalin-fixed paraffin sections of oral CIS and 10 cases of mild and moderate squamous epithelial displasia (SED) as a control were subjected to p53 immunohistochemistry. In the next step all cases were subjected to p53 gene mutations analysis by laser capturing microdissection and direct sequencing of PCR product for exon 4–8. Showed that p53-protein over-expression were found in basal layer of SED and the p53 protein over-expression were confined in the whole layer of CIS-basaloid type, basal and parabasal layers of CIS-verrucous type, and sporadically in the basal layer of CIS-acanthothic type. Mutational analysis for p53 gene showed 43% of total cases of CIS had p53 gene mutation therefore CIS-basaloid type had mutations more frequently than the other types and mutation in exon 8 more dominant than other exons, which had some common mutation at codons 196, 248, 282, 291, and 306, while no particular mutations were found in control (SED).Our criteria to diagnose several types of oral carcinoma in-situ by p53 protein expression and mutational analysis could be used to understand molecular behavior of CIS.

Abstract

Background: Diabetes mellitus is a metabolic disorder caused by insufficient insulin production due to pancreatic β cell destruction, whereas in gestational diabetics an increase of hormone estrogen induces insulin resistance. Oral candidiasis constitutes an opportunistic fungal infection due to a compromised immune system that is a medical condition reported by diabetics, including those suffering from gestational diabetes. Purpose: To determine the severity of oral candidiasis in female Wistar rats with type 1 and gestational diabetes mellitus. Methods: This research constituted a laboratory experiment incorporating a post test-only group control design whose subjects were female Wistar rats divided along the following lines: group 1 consisted of diabetic non-pregnant rats, group 2 contained diabetic pregnant rats induced by streptozotocin and the control group members constituted normal female rats. Diabetes induction was performed by means of 40 mg/kgBW streptozotocin administrated intraperitoneally. Diabetes mellitus was confirmed when the blood glucose level ≥ 120 mg/dL. All groups were exposed to 0.2 ml Candida albicans suspension (5x108 CFU/ml) in the oral buccal vestibule between the distal incisors and mesial maxillary first molar for three days. A swab was performed on the third day after final exposure before the samples were observed under a light microscope. Candida albicans cultivation and calculation of the resulting colonies was carried out on Sabouraud Dextrose Agar after they had been identified by means of a germ tube test. Results: The result confirmed the absence of hyphae in the control group, while in group 1 all samples contained hyphae. Moreover, group 2 featured a dense hyphae population. A chi-square test indicated a statistical significance (p<0.05) between all groups. Conclusion: Oral candidiasis in gestational diabetes is more severe than that occurring during type 1 diabetes mellitus.

Abstract

Background: Tooth loss can disrupt the mastication process. Mastication disorders limit the amount of food a person consumes, affecting nutrition. The number of functional tooth units (FTUs) can affect nutritional status, measured using the body mass index (BMI). Purpose: The purpose of this study is to analyse the effect of the number of FTUs on the BMI in the elderly. Methods: This research was conducted in four villages in the Jember Regency. The number of subjects was 189, aged 45 years and over. The number of FTUs was calculated based on the anterior and posterior teeth that have contact with the antagonist and the BMI using the BMI formula. The data was analysed using a linear regression test; the level of significance is 0.005. Results: A simple linear regression test showed that there was significant correlation between FTU and BMI (p=0.366). Conclusion: The number of FTUs affects BMI; the higher the number of FTUs, the greater the BMI.

Abstract

Background: Tooth eruption begins after crown and root formation and may be delayed by gestational diabetes mellitus. Metformin can control blood glucose levels through gluconeogenesis inhibition, and consuming thymoquinone for diabetic treatment will regenerate pancreatic β cells and reduce oxidative stress. Purpose: The objective of this study is to compare the tooth eruption in rats that were born with diabetes and are being treated with either metformin or thymoquinone. Methods: This study used 48 Wistar rats (Rattus norvegicus L.), and the rat sample was divided into four groups, including rats who were born from healthy mothers, rats who were born from untreated diabetic mothers, rats who were born from diabetic mothers that were treated with metformin and rats who were born from diabetic mothers that were treated with thymoquinone. Diabetes was induced by intraperitoneal injection of a single dose of streptozotocin (40 mg/kg BB). Each rat sample was taken with simple random sampling from different mothers, and body weight, blood glucose levels and levels of tooth eruption were recorded. Eruptions of the maxillary right first molar were measured from the cusp of the tooth to the alveolar epithelial lining. Results: Based on the measurements of tooth eruption, it was found that groups A, C and D were closer to mucosa on day 1, 7 and 14 than group B. Based on statistical analysis, there were significant differences (p = 0.03) between group B and groups C and D. Conclusions: Rats born from untreated diabetic mothers have more delays in tooth eruption than those born from diabetic mothers who are treated with metformin and thymoquinone. Thymoquinone has the potential to be an alternative to metformin because it has been shown to be similarly effective.

Abstract

Background: Pleomorphic adenoma (PA) is a benign salivary gland tumour with high incidence and recurrence after treatment. It may recur with the same appearance or develop toward malignancy, namely as carcinoma ex pleomorphic adenoma (CXPA). Howthis tumour can transform into a CXPA remains unclear. Purpose: The aim of this study was to analyse the possibility of pathogenesis and progressivity of PA to CXPA. Methods: Twenty-four samples of PA and three control samples of CXPA were stained with haematoxylin and eosin (HE), Mallory’s trichrome, and Periodic acid–Schiff (PAS). All of the PA cases were identified through different kinds of stroma, tumour cells types, morphologic patterns, or else through atypical appearance of the PA similar to the CXPA. Results: Twenty-four samples of PA demonstrated that the most dominant stroma was myxofibrous, and the dominant tumour cell type was plasmacytoid cells with a trabecular pattern. Additionally, in the pleomorphic histological picture of adenomas we found several patterns of malignant tumour behaviour, including pseudopodia, metaplasia and hyalinisation, and cholesterol crystals that are thought to come from fat cell necrosis derived from adipose metaplasia. Conclusions: PA displays several atypical characteristics that have the potential to develop into malignancies such as CXPA, due to capsular infiltration, necrosis, hyalinization and high mitotic activity of cells, but all these atypical characteristics that we observed still cannot be clearly classified as CXPA because they require other specific examinations.
