Active clinical trials for "Dental Pulp Necrosis"

assessment of bacterial reduction and post-operative pain following Laser activated irrigation using sodium hypochlorite and a 980 nm diode laser device as an adjunct to conventional root canal treatment, and comparing it with passive ultrasonic irrigation using sodium hypochlorite and an ultrasonic device in patients with single rooted asymptomatic necrotic teeth.

Comparing the postoperative flare ups and pain after adding the XP Endo Finisher to the final irrigation protocol on necrotic mandibular premolars.

this prospective in vivo randomized clinical is to evaluate the post operative pain (incidence ,degree and duration) with multiple full rotation file (protaper next ®) and single full rotation file (Neolix®) in treating maxillary and mandibular anterior and premolar with chronic pulpitis .Together with our aim from this trial ; we are trying to provide an evidence for the dentists in order to provide the best quality service with the least expenses and thus gaining the patients' trust and saving time, money and effort.

Regenerative endodontic procedures have been used to successfully treat human mature permanent teeth with necrotic pulps and apical periodontitis. Many researchers have begun to apply regenerative endodontic procedures to mature teeth in adult patients. Several clinical case reports have shown complete resolution of signs and symptoms of pulp necrosis in mature teeth, even those with large periapical lesions, as well as signs of pulp canal obliteration. thevaim of this study is To assess the regenerative potential of mature permanent teeth with necrotic pulps with platelet-rich fibrin (PRF) and blood clot using radiographic and clinical methods.

Aim to compare acute pain rate after single-visit ortwo-visits treatment of teeth with necrotic pulp and apical periodontitis .90 teeth with a diagnosis of pulp necrosis and apical radiolucency at the apex.Working length was established with EAL and confirmed radiographically. Flex-R files were used to complete canal preparation. Level ofdiscomfort were recorded and cases with acute postoperative pain.

The aim of this prospective in vivo randomized clinical trial to evaluate influence of combination of calcium Hydroxide (CALCIPAST Paste, Poland) and chlorhexidine Gel 2% (Gluco-Chex 2%, Cerkamed, Poland) in comparison to calcium hydroxide paste (CALCIPAST Paste, Poland) as Intracanal Medication on post operative pain (incidence, degree, duration) and reduction of bacterial endotoxins (quantitative) after endodontic treatment in single rooted necrotic teeth. According to the inclusion criteria the patients enrolled in the study and allocated randomly into three groups either combination of calcium hydroxide paste intracanal medication with 2% chlorhexidine gel. (group A) or calcium hydroxide paste intracanal medication only (group B) or mechanical preparation without intracanal medications (group C) the endodontic treatment is done at two visits. The samples of endotoxin divided into three groups: after access (S1), after mechanical instrumentations (S2), after removal intracanal medication (S3), all samples taken by a sterile paper points introduced in the root canal for the working length for 60 seconds. firstly the patient's medical and dental history is taken. the patients assign on informed consent. and then anaesthetized and access cavity performed and root canal preparation is done by Revo-s system then irrigation and intracanal medication placement inside to canal. the patient's record the post operative pain in sheet with NRS after 4, 24, 48 hours and 2 weeks after first visit. the operator will recall the patient to check the records second visit After 2 weeks from application of ICM, rubber dam will be applied then removal of the temporary dressing, then a sterile paper point (S3) will be introduced into the canals after irrigation and removal of the remnants of the intracanal medicament with the saline solution. Removal of the paper sample to determine the endotoxin concentration. The canals will be obturated by single cone technique using gutta percha point tapered 0.4% (Gutta percha point, Revo-S MicroMega CO., LTD, France) corresponding to the final apical size of the file and the root canal sealer will be resin sealer (Adseal, META BIOMED CO., LTD, Korea). Pain will be assessed by numerical pain rating scale (NRS) after 14 days from the first visit (at the day of the Obturation) before the beginning of Obturation.

The aim of this study is to evaluate the post treatment pain after instrumentation of root canals with a single file reciprocating (Wave-One Ni Ti file, DENTSPLY Maillefer) or rotary(One Shape, Micro Mega, France) file system in patient with asymptomatic necrotic molars This trial will help to clinically evaluate the use of reciprocating motion in endodontic treatment in necrotic teeth without periapical lesion therefore reduce the post-obtuation pain

This study aims to compare regenerative endodontics for necrotic young permanent anterior teeth using oral photo-activated disinfection versus triple antibiotic paste in terms of: Clinical success in terms of absence of any complication such as spontaneous pain, sinus or swelling. Radiographic success in terms of healing of periapical radiolucency or increase root thickness, length or apical closure.

Evaluation of post operative pain after pulpectomy procedures for primary molars with irreversible pulp damage and without periapical radulicency using two different systems (One shape file ( ratation movemont) and wave one gold file ( reciprocation movement)

The aim of this study was to evaluate the effectiveness of tactile sense, digital periapical radiograph and two different varieties of electronic apex locators at working length determination in primary molars. A total of 30 infected mandibular primary second molar teeth in twelve children aged between 5 and 8 years were included in this study. Working length determination was performed using tactile sense, radiographic method and two different varieties of electronic apex locators (ProPex Pixi® and Ipex®) separately.
