Active clinical trials for "Pulpitis"

The aim of this study was to compare post-operative pain following total pulpotomy (TP) and root canal treatment (RCT) in mature molar teeth with severe symptoms indicative of irreversible pulpitis. To compare the traditional pulpitis classification with the Wolters system in evaluating post-operative pain. Materials and Methods: Sixty-four mature mandibular molar with symptomatic vital pulps in patients aged 18-60 years were included and were classified according to the Wolters (moderate/severe pulpitis) and the traditional pulpitis classification (reversible/irreversible pulpitis). The teeth randomly divided into 2 groups. RCT was performed, using standardized protocols. TP was performed to the level of the canal orifices, and haemostasis was achieved with 2.5% NaOCl. 3 mm layer of MTA was placed as the pulpotomy agent. The treated teeth were restored with glass ionomer cement followed by composite. Pain was recorded 6, 12, 24, 48, 72 hours and 7 days after treatment. The data collected were statistically analyzed

The aim of this randomized clinical trial is to compare the antibacterial effects of sodium hypochlorite (NaOCl) and Polyhexamethylene biguanide during root canal treatment .

The Vibringe is the first endodontic sonic irrigation system that enables delivery and activation of the irrigation solution in the root canal, in only one step. The activation of the disinfectant by acoustic streaming, enriches and completes the irrigation procedure and improves the success rate of endodontic treatments. It has been shown that this system significantly improves debridement. It also improves the disruption of the smear layer and biofilm by activating irrigation solutions. As there are no previous studies comparing the Vibringe system with other irrigation techniques under clinical settings, in this regard, the aim of this study is to evaluate whether irrigation with Vibringe provides more or less benefit in terms of postoperative pain when compared with the conventional needle technique.

The aim of this study is effect of premedication on success of inferior alveolar nerve block injection. Sixty healthy adult volunteers including criteria, are participating. The patients will be divided into 3 groups and will be randomly given one of premedications including 1) 10 mg Ketorolac, 2) 10 mg Ketorolac plus 1000mg Acetaminophen, and 3)Placebo, 45 minutes before applying the injection. All patients will receive standard Inferior Alveolar Nerve Block injection . Patients with no lip numbness and positive responses to cold and electric pulp tests would be excluded from the study. Endodontic access preparation will be initiated 15 minutes after Inferior Alveolar Nerve Block injection. Pain during treatment will be recorded using a Heft parker Visual Analog Scale(VAS). Success will be considered as no or mild pain (VAS≤54) during caries/dentin removal, access cavity preparation and working lengths measurements. Data will be analysed using Mann-U-Whitney and Kruskal-wallis tests.

This is a clinical study that will investigate the occurrence of post-operative discomfort following the use of the Gentlewave System for root canal disinfection and irrigation. Assessment of discomfort level will be via a visualized analog pain scale.

Based on the changing understanding of carious biofilm development and caries progression, Sealing carious dentine beneath a restoration deprives the caries biofilm of nutrients and alters the environment sufficiently to slow or arrest lesion progression. This has the added benefit of avoiding pulp exposure and subsequent treatment .The evidence base supporting the biological approaches which include Hall technique has been steadily increasing in the last few years. This has given rise to a growing trend towards a biological approach by Paediatric dentists and has led to an increasing concern about the merits of conventional approach in treatment of carious primary molars .

Introduction: Local anesthetic failure is an unavoidable aspect of dental practice. A number of factors contribute to this, which may be related to either the patient or the operator. Patient-dependent factors may be anatomical, pathological or psychological1-3. Work is still going on by dental clinicians and researchers in order to find an optimal local anesthetic agent which it has a high potency and rapid onset of action.4-6. However, pain free injection also play a role in improving the patient perceptions toward the dentist and dental treatments and encouraging patients to attend a regular checkup5-8. Failure of the local anaesthetic injections using Inferior Alveolar Nerve Block (IANB) for lower teeth in asymptomatic and symptomatic patients requires additional buck-up strategies to achieve pain free dental treatment. Otherwise, the patient complains of severe pain and hindering the clinician to proceed to the dental treatment. Mechanism of action for intraseptal injection The route of diffusion and distribution of the anaesthetic solution in the intraseptal technique is most likely through the medullary bone (Fig. 1). It offers anaesthesia to the bone, delicate/soft tissues, root structure in the region of infusion. It is best when both pain control and haemostasis are wanted for delicate /soft tissue and bony periodontal treatment. Figure 1: Represents the point of needle insertion for the Intraseptal Injection and the position of the needle 3mm apical to the apex of the papillary triangle5. Advantages of intraseptal injection In contrast to IANB and local infiltration, the intraseptal technique prevents the anaesthesia of tissues such as lips and tongue hence, decreases the chances of cheek or lip biting (self-trauma). It necessitates minimum or least dosage of local anaesthetic and minimizes bleeding during the surgical procedure. This technique being less traumatic, has immediate or instantaneous (<30-sec) onset of action and comparatively less number of postsurgical complications14. Intravascular injection is extremely unlikely to occur15compared to IANB or infiltration. Assertions that intraseptal anaesthesia is immediate are properly consistent with previous clinical results. Their findings reported that the onset of action for anaesthesia was within one minute after injection. So the onset time can be considered rapid if not immediate. Disadvantages of intraseptal Injection Clinical experience and multiple tissue punctures may be necessary to perform this technique. During the anaesthetic procedure, the anaesthetic solution may leak in to the oral cavity resulting discomfort and an unpleasant or bitter taste. The effective period anaesthesia for pulpal and soft-tissues is very limited20 hence multiple repeats may be required for longer surgical procedures. The aim of this prospective clinical study is to determine the anesthetic efficacy of the supplemental intraseptal technique in mandibular teeth diagnosed with extraction when the conventional inferior alveolar

Aim: To compare the clinical antimicrobial and adverse effects of irrigation with Sodium Hypochlorite (NaOCl) 0.5% versus NaOCl 3% during root canal treatment. Methodology: Consecutive patients referred to a specialist clinic of endodontics are randomly assigned to have the root canal treatment performed with a concomitant irrigation either with a buffered 0.5 % NaOCl (Dakin's solution) or 3 % NaOCl. Teeth with vital or necrotic pulps and retreatment cases were included. Root canal treatment procedures varied but followed the routines of the Specialist Clinic of Endodontics, Public Dental Health, Gothenburg, Sweden. Immediately before the root canal filling a microbial sample is taken from the operative field and the root canal. The bacterial samples were processed at the laboratory as outlined by Möller (1966). After each visit each patient was instructed to fill in a questionnaire and assess his or her post-operative pain on a visual analogue scale (VAS), with endpoints 0= "no pain" and 10= "worst imaginable pain", for seven consecutive days. The Fischer's exact test was used for statistical analyses of the differences in outcome between the groups.

In this study, 120 primary molar teeth from healthy children aged between 5 and 9 and who apply to Marmara University Faculty of Dentistry, Department of Pediatric Dentistry will be subjected to pulpotomy treatments. After proper diagnosis of coronal pulpitis, the teeth will be assigned randomly to one of the 3 groups: 40 primary molars for formocresol (FC) pulpotomy treatments, 40 primary molars for ferric sulfate (FS) treatments and 40 primary molars for 0.5% hyaluronic acid gel (HA) pulpotomy treatments. The tooth decay will be removed, the pulp will be amputated from the chamber of the pulp with a sharp excavator and one of the medicament will be applied to the orifice of the root canals. The cavity will be sealed tight with zinc oxide cement, and the primary molars will be restored with a composite filling material or with a stainless steel crown (SSC). A single investigator will perform the procedure. The teeth will be followed clinically and radiographically at 1st, 3rd, 6th, 12th months.

Brief summary Background: A large proportion of dental practice involves the treatment of caries in the permanent dentition. In USA alone tooth related pain is annually responsible for 15 billions days lost through sickness. We do not know whether a stepwise excavation is better or worse compared with one final completed excavation in adults with deep caries with or without pain. A deep carious lesion is in the risk zone of being pulpal exposed during excavation. Aim: The aim of the CAP-1-trial is to investigate the beneficial effects of stepwise excavation during two visits versus óne completed excavation of deep caries in permanent teeth with or without pain. Patients: Consecutive patients contacting the units involved in the CAP trial for the treatment of deep caries. The trial will comprise 300 patients. Design: CAP-1-trial is a randomised patient- and observer-blinded multicenter trial, with two parallel intervention groups. Patients that fulfill the inclusions criteria and none of the exclusions criteria, will be centrally bloc-randomised in Copenhagen Trial Unit, Copenhagen DK, and stratified by age and pain. Allocation ratio is 1:1. Interventions and products: Patients are allocated for stepwise excavation in two visits or final excavation in one visit. The patients will not be informed about the result of the randomisation, i.e. the type of intervention. Therefore, all patients will be contacted for two visits. The second visit in the stepwise excavation group wil be used for the second and final excavation, and for the performance of a permanent restoration. The second visit in the one step excavation group will solely be used for the performance of a permanent restoration. The interventions in both groups are completed following 8-10 weeks after the randomisation. A temporary calcium hydroxide based material is used in both groups (Dycal®). The temporary restoration material, glas-ionomer cement is used (Ketac Molar®) in between visits, and a resin material is used for the final restoration(Herculite®).
