A total of 139 extracted mandibular second molars were injected with India ink and demineralized. They made clear transparent methyl salicylate, the anatomy their canals was studied. It found that 86.3% had two roots, 9.3% one root, 4.3% three roots. Ninety percent mesial roots (predominantly a type II or III configuration), 77.5% distal these teeth canal I configuration). Among molars, 7.2% C-shaped configurations seen mostly in single-rooted molars. The results this study indicate molar...
<b>Background:</b> The follicular tissue around impacted third molars has a potential to develop pathosis. However, it is generally assumed that the absence of abnormal radiolucency indicates presence normal follicle.<br><b> Aims:</b> aim this study was investigate abnormalities associated with radiographically molar impactions.<br><b> Materials and Methods:</b> One hundred eighty-five from 170 patients no signs (follicular space <3 mm) were used for study. Follicular tissues relevant teeth...
The purpose of this study was to compare the sealing ability gray mineral trioxide aggregate (GMTA), white MTA (WMTA), and both Portland cement as furcation perforation repair materials. A total 120 human mandibular first molars were used. After root canal obturation preparation furcal perforations specimens randomly divided into four groups 25 teeth each. In A, B, C, D filled with WMTA, GMTA, cement, type II respectively. Ten used positive controls no filling materials in 10 complete...
The purpose of this study was to investigate the eradication Enterococcus faecalis by high-power settings Er, Cr:YSGG laser irradiation in root canals extracted teeth.The bacteria entering canal system invade dentinal tubules, resulting persistent infections due limited penetration irrigation solutions into tubules. antibacterial effects different lasers have been investigated previous studies.Sixty newly maxillary central incisors were enlarged chemomechanically and sterilized after removal...
The aim of this study was to evaluate the bactericidal effects Nd:YAG laser on biofilm Enterococcus faecalis.It is difficult eliminate bacterial biofilms with routine endodontic preparation techniques. It might be possible remaining in root canals teeth lasers.The 60 extracted were prepared and E. faecalis formed within canals. Then randomly divided into four groups 15. Group 1 samples did not undergo any interventions, serve as controls. 2 underwent a 3-W beam for 10 sec. group 3 irrigated...
The mutagenic potency of materials used in dentistry is great concern. Ames test a bacterial reverse mutation assay, which to determine the mutagenicity potential chemicals. In this study, was compare effects three pulpotomy agents, namely, CEM cement, formocresol and ferric sulfate.TA100 strain Salmonella typhimurium evaluate different concentrations presence absence enzymatic system found rat liver S9 fraction. Negative controls were 1% dimethyl sulfoxide water. positive sodium azide...
The purpose of this study was to compare apical microleakage following canal obturation with lateral and thermoplasticized gutta-percha compaction techniques.Ninety extracted single-rooted maxillary teeth were used in study. Seventy randomly divided into two groups: One group obturated by technique the other Obtura II (thermoplasticized technique); 5 positive controls (without obturation) negative (with each group. specimens placed India ink for 48 h then halves. amount dye...
The purpose of this study was to evaluate the effect spreader penetration depth on apical microleakage using lateral compaction method. A total 96 extracted maxillary central incisors were instrumented step-back method, and randomly divided into following four experimental groups: A) with tug-back 1 mm short working length; B) without C) D) length. Microleakage evaluation conducted dye ANOVA test used for statistical analysis. results showed that there a significant difference in amount...
This study evaluates the effect of calcium hydroxide dressing on microleakage composite restorations following non-vital bleaching.A total 45 sound extracted human maxillary central incisors underwent endodontic treatment. The teeth were randomly divided into three groups (n=15). In group 1, access cavities restored with composite. 2, a bleaching procedure for one week before being 3, procedure, paste was placed in pulp chamber week. then specimens subjected to dye leakage test. data...
The aim of the present study was to electrochemically evaluate corrosion resistance RaCe and Mtwo files after repeated sterilization preparation procedures.A total 450 rotary were used. In working groups, 72 from each file type distributed into 4 groups. used prepare one root canal mesial extracted human mandibular first molars. procedure 2 8 canals. following irrigation solutions used: group 1, with 2.5% NaOCl; 2, normal saline; 3, 4, saline in manner described. autoclave evenly Files for a...
The aim of this study was to evaluate the effect RaCe, FlexMaster and ProFile rotary instruments on smear layer formation by scanning electron microscopy. Eighty-four caries-free freshly extracted human single-rooted teeth were selected divided into three groups, each containing 28 teeth. instrumented with sequentially: Group A: Rotary Instruments; B: C: RaCe Instruments. Instrumentation performed crown-down method according manufacturer's instructions. specimens then examined SEM Hülsmann's...
