Publisher : Faculty of Dentistry Universitas Padjadjaran

High-speed contra angle is a potential source of cross-infection due to its working system in blowing up water, saliva and microorganisms from the patients, as well as dental unit water line contamination. This experimental Quasy laboratory study aimed to determine the reduce of bacteria in high-speed contra angle after 70% alcohol swabbing and flushing for 30 seconds and identifying the presence of the pathogen. This study was conducted on 35 lower molar teeth with caries without abscess in patients during pulp opening with the contra-angle. Afterwards, the contra-angle was immersed in sterile aquadest and flushed. The immersed and flushed water were sampled then cultured on blood agar plates. The colony forming units were counted manually: Group I, was the control; Group II, after used on patients; and Group III, after treatment and swabbed with 70% alcohol and flushed. The data were statistically analyzed according to Anava and continued by test with least significant differences (LSD). The results showed that in bacterial identification there were pathogens. The bacteria amount was reduced after swabbing the contra-angle from 50.88±40.33 to 10.31±20.02 cfus. After flushing, the cfus decreased from 169.74±53.76 to 73.03±36.39. Based on the variant and LSD analyzes (p<0.01), CFU was significantly different among the three groups. Conclusion: 70% alcohol swabbing and flushing could reduce the bacterial amount in high-speed contra angle and there was the presence of Staphylococcus aureus and Pseudomonas aeruginosa on the usage of high-speed contra-angle.

The liver is an important organ for body metabolism process. Liver disease is one of serious health problems in developing countries including Indonesia. Liver damage is caused by viral infection, toxic agent exposure (medications, alcohol), hormonal disturbance, neoplasm and autoimmune diseases. The use of high dose paracetamol to reduce pain also leads to liver damage. Apple (Malus domestica) juice is a natural anti oxidant agent. This laboratory experimental study was performed to discover the effect of giving apple juice on damaged cell regeneration due to the use of paracetamol. The study was performed in 21 male mice from Swiss-Webster strain that were divided into group I, II, and III. Group, I served as control while group II received 1 mg/ml paracetamol dose for 5 days and Group III received 1 mg/ml paracetamol for 5 days and 1 ml of apple juice on the 5th to 10th day. The observation of the mice liver cells was conducted using a light microscope with 400x magnification to get the number of necrotic liver cells per view field. The results of this study showed a difference in the number of necrotic liver cells between Group II and III. ANOVA statistical test ( = 0.05) concluded that apple juice significantly helps regeneration process in damaged liver cells caused by paracetamol.

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.

One of the temporomandibular joint disorders that mostly occurs is disc displacement with reduction. Disc displacement that causes the displacement of condyle position can be evaluated by using radiograph. The Cone Beam Computed Tomography (CBCT-3D) is a radiograph equipment which is able to capture the condyle position from many directions. This research was aimed to see the condyle position in patients with disc displacement with reduction symptoms. This research was conducted to 11 patients with symptoms of disc displacement with reduction and 3 patients without symptoms of disc displacement with reduction as the counterpart. What was conducted to the sample was the radiographic imaging using CBCT-3D radiography, followed by measuring the joint space distance in the sagittal and coronal directions. The result of the research was analyzed using the T-test. Statistically, the result of the test showed a significant difference ( = 0.05) between patients with disc displacement with reduction symptoms and the patients without symptoms, in sagittal and coronal views. The conclusion led to the difference in condyle positions in patients with the disc displacement with reduction and patients without the symptoms which meant there was a condyle position displacement that caused the distance alteration in joint space in sagittal and coronal directions.
