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

The blunt end with side hole irrigation needles have some advantages. They can be placed close to irrigation area, produce turbulent motion of irrigation material, and not push debris to apical. There is no data about the effectiveness of blunt end with side hole irrigation needle to eliminate root canal bacteria in vivo, therefore the research about effectivity of this needle compare to conventional irrigation needle was permormed. In this study 12 samples were used and divided into two groups. The conventional irrigation needle in the first group was used as control and the blunt end with side hole needle was used in the second group. The bacteriological sampling and colony counting was conducted. The paired t-test analysis before and after irrigation showed significant difference on the first and second group. The result indicated that blunt end with side hole needle more effective in eliminating root canal bacteria than conventional needle. Supporting to this study a software of fluent had been done in vitro. The result showed blunt end with side hole needle produced turbulent motion of irrigating liquid and the conventional needle produced laminar motion.

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.
