Abstract:
Objective To evaluate the therapeutic effects of one visit root canal therapy(RCT) and several visit RCT for cracked teeth.Methods Cracked teeth with pulposis or apical disease were randomized to receive one visit RCTor several visit RCT,their responses were compared.Results The long-term therapeutic effects of one visit RCT were batter than those of several visit RCT,but the differences were not significant.The concomitant symptoms were significantly less and treatment time was significantly shorter in one visit RCT group as compared with several visit RCT group.Conclusion One visit RCT is recommended for the RCT of cracked teeth.Cite

Background: The aim of this study was to analyze the outcome and prognostic factors of root canal treatment (RCT) and endodontic microsurgery (EMS) in the treatment of apical periodontitis (AP), respectively, and to compare the outcome and prognostic factors between initial RCT and nonsurgical retreatment (re-RCT) for AP.Methods: Patients with AP were recruited from the Stomatology Department of Peking University Third Hospital from January 2016 to December 2019. Data were collected by medical records review. Univariate analysis of treatment outcome was performed for the total RCT group, initial RCT group, re-RCT group and EMS group, respectively. Multivariate logistic regression was performed for the three RCT groups, respectively, but not for the EMS group.Results: The overall success of treatment for AP was 73.8%. The success rate of RCT in 229 cases was 70.7%, while that of EMS in 34 cases was 94.1%. The failure of RCT was significantly higher for elderly patients [odds ratio (OR) =1.025, P=0.013], teeth with incomplete fracture (OR =7.082, P=0.013), teeth with a greater crown root ratio (OR =1.198, P=0.029), teeth treated by a general dentist (OR =2.16, P=0.042) and teeth with unqualified treatment (OR =2.841, P=0.002). Of the 166 teeth treated by initial RCT, the success was 68.1%. A greater crown root ratio (OR =1.333, P=0.004) was identified as a risk factor for treatment. Of the 63 teeth treated by re-RCT, the success was 77.8%. A lower success was observed in teeth with unqualified treatment (OR =5.291, P=0.018). With regard to EMS, the univariate analysis showed that none of the variables were significantly related to the outcome.Conclusions: For AP treated by RCT, age, incomplete tooth fracture, crown root ratio, doctor classification and unqualified treatment had a strong impact on determining outcome. For initial RCT, crown root ratio was a significant outcome predictor, while for re-RCT, unqualified treatment was a strong statistically significant factor. No significant difference was found between the success of initial RCT and re-RCT for AP.

Aim. To evaluate the incidence and severity of postendodontic treatment pain (PEP) subsequent to root canal treatment (RCT) in vital and necrotic pulps and after retreatment. Methodology. A prospective study. Participants were all patients () who underwent RCT in teeth with vital pulp, necrotic pulp, or vital pulp that had been treated for symptomatic irreversible pulpitis or who received root canal retreatment, by one clinician, during an eight-month period. Exclusion criteria were swelling, purulence, and antibiotic use during initial treatment. A structured questionnaire accessed age, gender, tooth location, and pulpal diagnosis. Within 24 h of treatment, patients were asked to grade their pain at 6 and 18 hours posttreatment, using a 1–5 point scale. Results. RCT of teeth with vital pulp induced a significantly higher incidence and severity of PEP (63.8%; 2.46 ± 1.4, resp.) than RCT of teeth with necrotic pulp (38.5%; 1.78 ± 1.2, resp.) or of retreated teeth (48.8%; 1.89 ± 1.1, resp.). No statistical relation was found between type of pain (spontaneous or stimulated) and pulp condition. Conclusion. RCT of teeth with vital pulp induced a significantly higher incidence and intensity of PEP compared to teeth with necrotic pulp or retreated teeth.

Objective: To investigate whether therapeutic efficacy of single visit root canal treatment, when compared to multiple visits root canal treatment for permanent teeth, has no significant different outcome of healing rate. Methods: PubMed database was systematically searched on clinical trials together with searching in Biomed Central, Open Access, Google scholar. They were all filtered for English articles from 1990 until 2012. The included studies were randomized controlled clinical trials comparing healing rates of single and multiple visit root canal treatment. The healing rates were evaluated by clinical characteristics and radiographic interpretation. Data in those studies were extracted and analysed using stata 11.2 software Results: Seven articles were included an analyzed. Difference between two treatment modalities was calculated with relative risk of 0.78 (95% CI 0.56-1.09).Due to the homogeneity of data, quantitative systematic review was undertaken by fix-effect model. The healing rates of single and multiple visits root canal treatment were 86.3% และ 83.4% respectively. Evidence suggests that single visit root canal treatment has no differences of healing rates compare to multiple visits root canal treatment.(p=0.15) Conclusion: The healing rate between single visit root canal treatment and multiple visits root canal treatment was not statistically significant different.

Objective To evaluate the post-operative outcomes of one-visit endodontic treatment after a short clinical observation. Methods 107 teeth were included in one-visit root canal therapy group.The standardized protocols for root canal preparations and filling were performed.The clinical outcomes were evaluated after one week and half a year respectively. Results The cure rates of one-visit group were 95.3%.There were no significant differences between the one-visit group and those of two-visit group. Conclusion One-visit endodontic treatment has the same clinical efficacy as two-visit. With limited numbers of visits, it is promising for a regular therapy methods.

This cross sectional study investigated the clinical and radiographic status of crowned teeth with and without root canal treatment. The study used secondary data from records of patients who received crown treatment at the Faculty of Dentistry, University of Malaya before 2015 and walk-in patients attending the primary care clinic between July - December 2016. The inclusion criterion was crown fitted for more than 12 months. Once identified, the patients were assessed for clinical and radiographic status. Data were entered into and analysed using SPSS Version 20 software. A total of 66 crowns [35 root canal treated (RCT) and 31 non-root canal treated (n-RCT)] were identified. Chi-square test was carried out to determine the health of crowned teeth and for its longevity in the oral cavity. There were 43 crowns (46.5% RCT; 53.5% n-RCT) with plaque accumulation, 15 (66.7% RCT; 33.3% n-RCT) with gingival swelling/recession, 17 (46.5% RCT; 53.5% n-RCT) with widening of the periodontal ligament, 13 (53.8% RCT; 46.2% n-RCT) with bone loss and 5 (60% RCT; 40% n-RCT) crowns with periapical lesion. There was no statistically significant difference except for poorer alveolar bone condition for crowns that have been in the mouth for >10 years. Based on the study, no significant adverse pulpal involvement between crown with RCT and crown without RCT was observed.

Background: Root canal treatment (RCT) is a standard element of dental therapy. Several studies have demonstrated that most of the clinicians complete RCT on patients in multiple visits. However, in the last few decades several researchers in over 70% of the medical centers worldwide have advocated a single-visit RCT. Objective: The objective of this study was to compare the incidence and intensity of post-obturation pain after single- and two-visit RCT on vital and nonvital maxillary and mandibular single-rooted teeth. Materials and Methods: Data were collected from the 140 patients who were classified and treated in two groups, Group A (n=70) with single-visit obturation and Group B (n=70) with two-visit obturation. Results: In this study, it was observed that post-operative pain related with single-visit (Group A) RCT was overall similar as the post-operative pain associated with two-visit (Group B) treatment. In this study, sterile cotton pellet was positioned in the root canals between visits. Discussion: In this comparative study, under the studied conditions no difference in post-operative pain between patients treated in single-visit and patients treated in two-visit was observed. Thus, the present study demonstrates that two-visit endodontics is not helpful in reducing the pain incidence and that RCT completion in single-visit can be safe.

Introduction: The awareness of patient-centered outcomes regarding the sequel of endodontic therapy in everyday life is limited. This study aimed to quantify the impact of root canal treatment in one visit compared to root canal treatment in multiple visits on oral health-related quality of life (OHRQoL). Material and Methods: This is a controlled clinical trial, in which 32 patients were included; the age range was 16–60 years. At the patient's convenience, participants were divided into two groups: the first group received a single-visit treatment and the other group received a multiple-visit treatment. Conventional endodontic treatment was performed for indicated teeth by undergraduate dental students in a single visit or multiple visits. OHRQoL was recorded using an Arabic Oral Health Impact Profile (OHIP) questionnaire. Results: A total of 32 patients, with a mean age of 30.5 (SD = 8.2), received root canal treatments and filled OHIP questionnaire. Male patients composed 50% of the sample. The majority of the patients had a high school education (75%). Single-visit root canal treatment significantly improved OHRQoL by 7.6 points (P = 0.001) and multiple visits by 8 points (P = 0.001). Conclusion: Both single and multiple visits endodontic treatments equally improved OHRQoL.

The aim of this study was to compare post-operative pain following one-visit pulpectomy and placing stainless steel crown (SSC), with two-visit treatment (performing pulpectomy at the first visit followed by placing SSC at the next visit one week later) in vital pulp of primary molars with carious involvement.In this randomized clinical trial, 100 children aged 6-12 years with a carious primary molar tooth in need of pulpectomy were randomly divided into two groups of 50 each. In one-visit group, pulpectomy and placement of SSC were carried out at the same appointment. In two-visit group, pulpectomy of root canals was carried out at the first visit and placement of SSC was performed at the second visit one week after the first appointment. Post-operative pain was recorded using visual analogue scale (VAS) during one week after each treatment visit.No significant difference was found in the mean age and gender distribution between the two groups (P˃0.05 for both comparisons). Findings revealed that in the two-visit (pulpectomy) group during first three days and 4-7 days after the first treatment appointment, pain felt by the children was significantly lower than that felt by the one-visit group at the same time period (P˂0.0001 for both comparisons). Moreover, children in two-visit (pulpectomy) group consumed significantly lower amount of analgesics than those in the one-visit group (P<0.0001).No significant difference was found between pain felt by children during the first three days following one-visit pulpectomy and placement of SSC at the same appointment. Therefore, one-visit treatment of vital primary tooth is recommended.
