Green tea (Camellia sinensis) has been widely known as a healthy drink since long time ago. One of the substances in green tea which can give health benefit is catechin, an antibacterial substance. The purpose of this research is to know the efficacy of rinsing with green tea extract to Streptococcus alpha growth on gingivitis patientâs dental plaque. The research subjects include 30 mild gingivitis patients, and these subjects are divided into two groups: treatment group (20 patients) and control group (10 patients). Ten patients of treatment group rinse their mouth with 0.25% green tea extract and 10 other patients with 0.5% green tea extract. Meanwhile, control group use Bactidol (0.1% Hexetidine). Rinsing the mouth is performed every morning and night for five days. Sampling is conducted on the first and sixth day. Before rinsing data is analyzed using ANOVA and the result shows a significant difference. ANAVA testing then is done using proportion value. ANAVA Testing result shows that there is no significant difference among the patients in the treatment group. This result indicates that the effect of rinsing with 0.25% and 0.5% green tea extract is equivalent to the control (0.1% Hexetidine) to inhibit S. alpha growth on mild gingivitis patientâs dental plaque. From these two concentrations, it has not been known which one is the most effective concentration to inhibit S. alpha growth on mild gingivitis patient.

Smoking is the biggest factor for oral cavity malignancy. An oral cavity mucous swab was performed to 30 smokers (mild, moderate and severe) and 10 non-smokers which were followed by immunocytochemistry smear using the antibody for EGF-R, c-erbB, and HSV-1 antigens to reveal the effect of smoking on the occurrence of oral cavity malignancy. The results from this experiment are analyzed statistically using one-way Anava. It is discovered that based on the assessment of the expression level towards EGF-R, and C-erbB oncogene there is a very significant difference between the smoker group and non-smoker group (p < 0.01). Meanwhile, the results from the assessment towards HSV-1 oncogene do not show significant differences between the smoker group (mild, moderate and severe) and the non-smoker group (p > 0.05). The results of this study show that the more a person smokes, the higher possibility of oral cavity malignancy and that the antibody for EGF-R and c-erbB can be used as a marker for early detection of oral cavity malignancy caused by smoking.

Effectiveness of EDTA as the irrigation solution to remove smear layer in root canal Achiar, Kurniasri Amas; Sukartini, Endang

Publisher : Faculty of Dentistry Universitas Padjadjaran, Indonesia

One of the objectives of successful endodontic treatment is the hermetic obturation of the root canal system. To achieve this, the root canal filling must seal the canal space both apically and coronally to prevent the ingress of microorganisms or tissue fluids into the canal space. Apical leakage is reported a common reason for the clinical failure of endodontic therapy. Leakage through an obturated root canal is expected to take place at interfaces between sealer and dentin or sealer and gutta-percha, or through voids within the sealer. Hence, the sealing quality of root canal filling depends much on the sealing ability of the sealer. Therefore, anything that may influence the adaptation of the root filling to the canal wall is can determine the degree and the extent of leakage, and ultimately the prognosis of the endodontic therapy. In endodontic therapy, the smear layer formation results from root canal preparation and may influence the effective seal of the root canal system. The smear layer formation is mainly composed of inorganic components (dentin debris) and organic materials, such as pulp tissue remnant, bacteria, and blood cells. Removal of the smear layer from the root canal walls before the obturation can reduce the leakage of root canal sealer. To remove the smear layer use 10 ml 17% EDTA followed by 10 ml of 5.25% NaOCl as irrigating solution. This paper discribe about how the effectivity of EDTA as irigating solution to remove the smear layer especially in the apical root canal with many lateral canal to reduce the apical leakage.

Dental erosion is defined as irreversible loss of dental hard tissue, caused by acid condition in the oral cavity without bacterial involvement. One of the signs of dental erosion is calcium dissolution of the enamel. Yoghurt is a fermented beverage that has low pH level due to lactic acid. The aim of this study was to measure the solubility of calcium enamel after soaking in yoghurt for 12 and 18 hours. Twenty-four premolars were divided into 4 groups. Group A and B were soaked in milk for 12 and 18 hours; group C and D were soaked in yoghurt for 12 and 18 hours. Atomic Absorption Spectrophotometer (AAS) was used to measure the solubility of calcium from each sample. Data were analyzed using one-way ANOVA and LSD (p < 0.05). This study indicated that soaking premolars in yoghurt for 18 hours has greater enamel calcium dissolution than in yoghurt for 12 hours. It can be concluded that prolonged soaking premolars in yoghurt will increase the calcium enamel dissolution.

The dental alloy is widely used in many fields of dentistry as a restoration material, orthodontic, prosthodontic, oral surgery and endodontic treatments. Naturally, most of the metallic materials without exception to stainless steel alloy will experience a process of corrosion in a form of electrochemical reaction to achieve thermodynamic equilibrium. The corrosion process in the oral cavity is due to the reaction of metal with saliva as an oral cavity electrolyte fluid. SSC has preformed restoration material conform with dental anatomy, manufactured from stainless steel alloy which is formable and adaptable to the teeth. Stainless Steel Crown generally made of austenitic stainless steel 18/8 of AISI 304 group contain chrome 18% and Nickel 8%, can be used as a restoration for teeth with excessive caries, crown fracture, email hypoplasia, or restoration after endodontic treatment. The toxic effect of Ni+2 released due to corrosion process may cause an inflammation of the gingiva and periodontal tissue. Laboratorically this condition indicated by the expression of pro-inflammation cytokines as immunological parameters such as IL-6, IL-8, TNF and IL-1Î² whose main role is to initiate and enhance any inflammation responses. The presence of pro-inflammation cytokines can be detected as soon as 1 hour after placement of SSC by examination of gingival crevicular fluid (GCF) by ELISA technique. The magnitude of the toxic effect depends on corrosion rate and ions release which is influenced by metal chemical composition, environment temperature and pH, metal wear due to abrasion and friction, soldering if any, and elongation of the metal. Conclusion: The release of Ni+2 during corrosion process after placement of SSC cause gingival inflammation which is indicated by the change of the immunological parameters.

In early research, gypsumâs product from Padalarang and Tasikmalaya had been compared and it is found that Tasikmalaya gypsum was better. In these research, itâs used gypsum product from Tasikmalaya with wet calcination method using autoclave. This research consisted of four samples divided into three control groups and one treatment group. Researchâs sample consisted of 45 units and 15 units data from the last research. To compared physical and mechanical properties, every samples was tested in three treatments. Research results showed that the average setting time, setting expansion and compressive strength of wet calcination gypsum product are respectively 487.6 seconds, 0.492%, and 12.708 Mpa. The results were statistically analyzed with MANOVA and Tukey test. The analysis showed differences in physical and mechanical properties between self made gypsum product from Tasikmalaya with Padalarangâs and two marketed gypsum products. Setting time self made gypsum product meets the ISO for type III, while compressive strength and setting expansion were not. But gypsumâs production from Tasikmalaya done by wet calcinations had better physical and mechanical properties, so it can be used in dentistry.
