Active clinical trials for "Tooth, Nonvital"

The aim of the present study is to clinically compare the incidence of postoperative pain after root canal preparation using TruNatomy system and HyFlex Electrical Discharge Machined (EDM) rotary system in asymptomatic necrotic mandibular molars.

Aim of the study is to assess canal disinfection using matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) in single visit and multiple visit regeneration protocols, and to assess clinical and radiographic outcomes of single visit and multiple visit regeneration protocols.

The purpose of this randomized controlled clinical trial is to use Allium sativum oil as non-vital Pulpotomy medicament compared to Formocresol in primary teeth by evaluating its antibacterial effect against Streptococcus mutans and Lactobacillus acidophilus. It is hypothesized that there is no difference in the antibacterial effect of Allium sativum oil compared with Formocresol, when used as non-vital Pulpotomy medicaments.

Maintaining Apical patency during root canal treatment is a widely followed methodology in modern endodontic treatment protocols. It involves passing of a small #08 or #10 K file through the apical foramen during root canal shaping without widening it. it is done to keep the foramen and apical thirds of root canal free of debris. proponents of the procedure claim it to improve irrigation; provide better tactile feedback; reduce the chances of procedural errors; reduce transportation and reduce pain following root canal procedures. however, there is no clinical trial which specifically evaluates the effect of apical patency on outcome of root canal procedure. hence this study was designed to evaluate the effect of apical patency on outcome of root canal treatment.

This randomized clinical trial compares the effects of intracanal medicaments on the incidence of postoperative pain and flare-up in asymptomatic retreatment cases.

Aim: The aim of this prospective study was to evaluate the treatment outcomes of regenerative endodontic technique (RET) for the management of traumatised non-vital immature teeth in children. Methodology: This study aims to recruit 25-30 healthy children with traumatised non-vital immature upper incisors to be treated with bi-antibiotic regenerative endodontic technique. Patients will be reviewed clinically at 3m,6m,9m,12m,2y,and 3 years and radiographically at 3m,9m, 2y,and 3 years. One operator will undertake all treatments, clinical reviews and standardised radiographic exposures. Radiographic analysis will be carried out by two calibrated experienced clinicians. Standardised photographs will be taken at 3m,12m,2y,and 3 years and crown colour changes will be assessed using a standardised validated methodology.

The purpose of this clinical study was to compare the effectiveness of passive ultrasonic irrigation with that of traditional syringe irrigation on the removal of bacteria and endotoxin (lipopolysaccharide [LPS]) from root canals.

The purpose of this randomized controlled clinical trial is to use Turmeric gel as non-vital Pulpotomy medicament compared to Formocresol in primary teeth by evaluating its antibacterial effect against Streptococcus mutans and Lactobacillus acidophilus. It is hypothesized that there is no difference in the antibacterial effect of Turmeric gel compared with Formocresol, when used as non-vital Pulpotomy medicaments.

The purpose of the study is to use Allium sativum oil and Turmeric gel as non-vital Pulpotomy medicaments in primary teeth by evaluating their antibacterial effect against Streptococcus mutans and Lactobacillus acidophilus. It is hypothesized that there is no difference in the antibacterial effect of Allium sativum oil and Turmeric gel when used as non-vital Pulpotomy medicaments.

Endodontic treatment is performed frequently which often results in weakening of tooth structure. Coronal restoration is done to restore these endodontically treated teeth. Posts have been used to retain the coronal restoration and reinforce these teeth but unfortunately posts placement results in further weakening of tooth structure. Newer contemporary core buildup materials will be used to restore coronal part of tooth without using endodontic posts and then the fracture resistance of these teeth will be evaluated. This study will be performed to evaluate the fracture resistance of endodontically treated teeth restored with newer contemporary core buildup materials. 80 recently extracted single rooted caries-free and unrestored premolars will be taken and mounted in acrylic resin blocks. Roots of teeth will be covered with light bodies of condensation silicone impression material to simulate periodontal ligaments. Class 1 and class 2 cavities will be prepared and endodontic treatment will be performed in these teeth specimens. Coronal restoration will be done with three core buildup materials (Cention-N, Zirconomer and Aristaloy Amalgam). Teeth specimens are then divided into group 1 and group 2 (class 1 cavity preparation and class 2 cavity preparation respectively) and each group is further divided into four subgroups: Subgroup A: Control group Subgroup B: Cavities restored with Zirconomer (Shofu) Subgroup C: Cavities restored with Cention-N (Ivoclar vivodent) Subgroup D: Cavities restored with Aristaloy Amalgam (Cookson) Fracture resistance of endodontically treated teeth restored with different core buildup materials will be tested by the Universal testing machine.
