Abstract

Calcium Hydroxide point and Chlorhexidine point are new drugs for eliminating bacteria in the root canal. The points slowly and controly realease Calcium Hydroxide and Chlorhexidine into root canal. The purpose of the study was to determined the effectivity of Calcium hydroxide point (Calcium hydroxide plus point) and Chlorhexidine point in eleminating the root canal bacteria of nescrosis teeth. In this study 14 subjects were divided into 2 groups. The first group was treated with Calcium hydroxide point and the second was treated with Chlorhexidine poin. The bacteriological sampling were measured with spectrofotometry. The Paired T Test analysis (before and after) showed significant difference between the first and second group. The Independent T Test which analysed the effectivity of both groups had not showed significant difference. Although there was no significant difference in statistical test, the result of second group eliminate more bacteria than the first group. The present finding indicated that the use of Chlorhexidine point was better than Calcium hydroxide point in seven days period. The conclusion is Chlorhexidine point and Calcium hydroxide point as root canal medicament effectively eliminate root canal bacteria of necrosis teeth.

Abstract

5% tetracycline hydrochloride and 15% EDTA as a root canal irrigant have been proven to be able to remove smear layer, open dentinal tubules and have antimicrobial activity. An effective root canal irrigation solution must be able to dissolve organic and anorganic debris, lubricate endodontic instruments, disinfect microorganism and non toxic. The purpose of this laboratory experimental study was to determine cytotoxicity differences between 5% tetracycline hydrochloride and 15% EDTA. 21 samples were used and classified into 3 groups: control, 5% tetracycline hydrochloride and 15% EDTA groups. Cytotoxicity test was done using BHK21 cells. The data was analyzed using Bird and Forrester formula. It concluded that 5% tetracycline hydrochloride more toxic than 15% EDTA as a root canal irrigant.

Abstract

Background: One of the success criteria for a composite resin restorative material is the surface roughness that can be achieved through polishing. Considering that there are so many types of composite resin materials on the market, including polycrystalline composites, information on this type of composite’s surface roughness is needed. Purpose: The aim of this laboratory experiment was to compare the surface roughness difference between microhybrid and polycrystalline composite after polishing. Methods: In order to obtain this, a laboratory experiment was done. Four groups of composites were produced, the first two groups consist of microhybrid composite and the second two groups consist of polycrystalline composite. Two groups with the same material were treated with two different treatments as follows: the first group was not finished (the surface is under celluloid matrix), the second group was finished and polished. After these treatments, each sample’s surface was measured using surface roughness measuring instrument and then the Results: were analyzed statistically using independent t-test (α = 0.05). Conclusion: The result showed that after polishing, the surface roughness of polycrystalline composite is lower than that of microhybrid composite.

Abstract

Background: Root canal irrigation is an important stage in root canal treatment as it is requires to eliminate necrotic and debris tissue as well as root canal wetting. Unfortunately, root canal irrigation can cause the material utilised to pass into the apical foramen leading to periapical complications. Consequently, the irrigation solution should have low toxicity. Sodium hypochlorite (NaOCl) is a commonly used irrigation solution since it has antibacterial properties. Moreover, NaOCl is also known to have the ability to dissolve necrotic tissue, vital pulp tissue and organic components of dentin and biofilms. Nevertheless, it can still cause damage when coming into contact with periapical tissues. On the other hand, Mangosteen peel extract (Garcinia mangostana L.), also has antibacterial activities. Hence, Mangosteen peel extract is assumed to be employable as an alternative irrigation solution. Purpose: This research aimed to reveal the toxicity levels of NaOCl and Mangosteen peel extract (Garcinia mangostin L.) used as irrigation solution in human periodontal ligament fibroblast cells (HPdLFc). Methods: HPdLFc were obtained from periapical tissues taken from one third of the first premolar teeth cultured. These cells were subsequently divided into several groups exposed to NaOCl and Mangosteen peel extract at certain concentrations. A toxicity test was then conducted using MTT assay. The results were analyzed with an Elisa reader. Cell deaths and LC50 were then calculated. Results: NaOCl became toxic at a concentration of 0.254 µl/ml or 0.025%, while Mangosteen peel extract became so at one of 2.099 ug/ml or 0.209%. Conclusion: NaOCl can be toxic at a concentration of 0.254 µl/ml or 0.025% and Mangosteen peel extract at one of 2.099 μg/ml or 0.209%.

Abstract

Background : There are some factors can cause endodontic failure such as inadequate in cleaning or shaping step, non hermetic obturation, or poor restoration, which can cause bacteria multiply. Purpose : To report the management of endodontic failure with nonsurgical treatment. Case : 46-year-old woman came to Airlangga Dental Hospital Conservative Dentistry Department to treat her upper right tooth which show symptomatic pain in the last 2 weeks. The tooth has been treated and crowned with porcelain fused to metal about 10 years ago. Clinical examination show the presence of fistula on premolar buccal gingiva, react to percussion.? Radiographic examination show not hermetic obturation in one root canal and radiolucency in the periapical area. The diagnosis for maxillary first premolar is previously treated tooth with chronic periapical abscess.. Treatment : Crown and post was removed from the tooth, and endodontic retreatment was done. Follow up 6 months after the retreatment show no reaction to percussion, and radiographic examination show no enlargement periapical lesion. Conclusion : Nonsurgical endodontic retreatment always become the first choice to resolve endodontic failure for previously treated tooth.Keywords : endodontic failure, maxillary first premolar, nonsurgical endodontic retreatmentCorrespondence: Yongki Hadinata W., drg.
