AIM AND OBJECTIVE To compare the fracture resistance of teeth prepared with rotary system and filled with single cone guttapercha followed by lateral condensation with different sealers like zinc oxide eugenol and resin based (AH26) to that of resilon. MATERIALS AND METHODS A total number of 70 extracted intact human permanent maxillary incisors were selected. All prepared samples were divide...

Objective: To find out the post-obturation pain with Sealapex and AH26 Sealers on first, third seventh day.
 Study Design: Quasi-experimental study.
 Place Duration of Study: Armed Forces Institute Dentistry, Rawalpindi Pakistan, from May to Nov 2019.
 Methodology: Three hundred eighty-eight patients either gender, ranging age 20 45, presenting in OPD for root canal treatment wer...

UNLABELLED   INTRODUCTION Blood contamination of the canal during preparation can be a major problem in endodontics; this may result in apical microleakage. The aim of this in vitro study was to evaluate the effect of blood on apical microleakage of a resin-based root canal sealer (AH26) and a polymer-based root canal sealer (Epiphany). MATERIALS AND METHODS In this experimental study, 50 d...

The purpose of this study was to determine the effect of ultrasonic vibration on the force required to remove prefabricated posts. Ninety-six extracted human canines were divided into eight groups, which were prepared and obturated with gutta-percha and either a eugenol-containing (Roth's 801 Elite) or eugenol-free (AH26) sealer. Titanium #6 Parapost XH posts were cemented with either zinc phos...

BACKGROUND To evaluate and compare in vitro the antibacterial efficacy of five antibiotics when added individually to five endodontic sealers against Enterococcus faecalis (EF). MATERIALS & METHODS This controlled trial with systematic allocation method was carried out to detect the combined antibacterial activity of five endodontic sealers (Kerr sealer EWT, Endomethasone, AH26, AH Plus, Roek...

INTRODUCTION The purpose of this ex vivo study was to determine the releasing characteristics and doxycycline dentinal diffusion of AH26 sealer-doxycycline combination from apical 3mm of tooth root and apical foramen. MATERIALS AND METHODS One-hundred and two recently extracted single-rooted human teeth were decoronated and prepared with #3 and #4 Gates-Glidden drills and rotary Mtwo files. S...

AIM The focus of this study was to examine the staining potential of calcium hydroxide (Ca(OH)2) on tooth structure following the removal of AH26 root canal sealer. METHODS AND MATERIALS Fifty maxillary anterior teeth were prepared and obturated with AH26 and gutta percha. The sealers were then removed 24 hours later and the teeth were randomly divided into two groups. Ca(OH)2 was then placed...

Sealer placement techniques have not been examined in teeth with curved canals prepared with Lightspeed instruments. Three traditional methods of placing sealer were studied, using 45 extracted human single-rooted teeth, divided into 3 groups of 15. Root canal preparations were made with Light-speed nickel-titanium, engine-driven instruments. AH26 sealer was applied with either K-file, lentulo ...

INTRODUCTION Antibacterial activity is one of the desirable properties of an ideal sealer. This study aimed to compare the antimicrobial effect of three different sealers, i.e. resin (AH26), calcium hydroxide (Apexit) and zinc oxide eugenol (ZOE) based sealers. MATERIALS AND METHODS Direct contact test with agar diffusion was used in this in vitro study. The freshly mixed sealers were AH26, A...

eradication of microorganisms present in the root canal system is paramount for the successful outcome of root canal therapy. the purpose of this study was to compare the of doxycycline absorbed from mtad into root canal dentin after obturation with gutta-percha/ah26 and resilon/realseal at different time intervals.fifty-one extracted human teeth were instrumented. thirty samples were obturated...
