Successful root canal treatment depends on the adequate elimination of pathogenic bacteria. This study evaluated the effectiveness of a novel 445-nm semiconductor laser in reducing bacteria after chemomechanical root canal treatment. Microbiological specimens from 57 patients were collected after emergency endodontic treatment, in the following sequence: 1, removal of the temporary filling material; 2, chemomechanical treatment; 3, rinsing with sodium hypochlorite (3%) along with one of three adjuvant protocols (n = 19 in each group). The adjuvant procedures were: (a) sodium hypochlorite rinsing alone (3%); (b) laser irradiation; (c) combined sodium hypochlorite rinsing and laser irradiation. The diode laser was set to 0.59 W in continuous-wave mode (CW) for 4 × 10 s. After the flooding of the root canal with saline, specimens were collected using paper points and analyzed microbiologically. Statistically significant reductions in the bacterial load were observed in all three groups (p < 0.05): 80.5% with sodium hypochlorite rinsing alone and 58.2% with laser therapy. Both results were lower than with the combination of sodium hypochlorite rinsing and 445-nm laser irradiation, at 92.7% (p < 0.05). Additional disinfection of the root canal can thus be achieved with 445-nm laser irradiation after conventional chemical disinfection with sodium hypochlorite solution.

Objective: To compare the clinical efficacy of 2.5% non-heated sodium hypochlorite and 2.5% heated sodium hypochlorite as irrigation to control postoperative pain in single visit root canal treatment. Study Design: Comparative analytical study Place and Duration: Operative dentistry department of Liaquat University of Medical and Health Sciences, Jamshoro for 6 months duration from March 2017 to September 2017. Material and Methods: A total of 60 patients with single rooted maxillary and mandibular permanent teeth were randomly allocated into two groups. 30 patients were in group A and treated with non heated sodium hypochlorite solution and 30 patients in group B were treated with 2.5% heated sodium hypochlorite solution. In both groups, the level of pain was measured postoperatively after 48 hours by using Heft Parker visual Analog Scale of 10 and information was collected on Performa. Results: The average age of the patients was 28.62±6.06 years. There were 40(66.7%) male and 20(33.3%) female. Pain was reduced in both groups but there were no significant difference in reduction of pain between groups (p=0.640). Conclusion: Severity of pain was not statistically significant between groups. At 48 hours, Pain was reduced in both groups but there were no significant difference in reduction of pain between groups. Heated sodium hypochlorite to relieve postoperative pain, it should be new trend for recommendation for treatment of irreversible pulpitis in single visit root canal treatment. Key Words: Root canal, Heated sodium hypochlorite, Postoperative pain.

OBJECTIVES: The aim of this study was to determine the effect of Er:YAG laser irradiation used to clean dentinal walls on the apical sealing of root canals filled with different types of sealers. Background Data: Laser application to the dentinal walls removed debris, rendering the root canals free of smear layers and leaving the dentinal canaliculi open. METHODS: Sixty-four maxillary canines obtained from laboratory files were instrumented with K-files (Dentsply, Maillefer, Ballaigues, Switzerland) using the crown-down technique, and irrigated with a 0.5% sodium hypochlorite solution. The specimens were divided into two groups of 32 teeth each. In group I, the teeth were instrumented and irrigated with sodium hypochlorite solution, and divided into four subgroups to be sealed with the different materials (Endofill, N-Rickert, Sealapex and Sealer 26). In group II, the root canals were subjected to Er:YAG laser irradiation (200 mJ, 7 Hz and 60 J total energy), followed by root canal sealing as in group I. RESULTS: The data showed lower levels of apical microleakage in the teeth filled with N-Rickert, Sealapex and Sealer 26 cements than in those sealed with Endofill (p < 0.01). No significant difference in microleakage was observed between teeth irrigated only with 0.5% sodium hypochlorite and those submitted to Er:YAG laser application (p > 0.05). CONCLUSIONS: The Er:YAG laser irradiation applied to the root canal walls was not able to prevent apical microleakage.

The aim of this study was to evaluate apical sealing after root canal treatment using two different rotary instrumentation techniques and two thermoplastic root canal filling techniques. The study was performed in 115 human extracted mandibular premolars. After coronary access the apical foramen was opened with a # 15 K file 1 mm beyond the apex. Cleaning and shaping was subsequently carried out at the working length, 1 mm from the apex, with ProFile .04/.06 system (Dentsply/Maillefer), Quantec (Analytic Endodontics/Kerr) or by the step-back technique with 1% sodium hypochlorite solution as irrigating solution. The root canals were filled with Thermafil (Dentsply/Maillefer) or Microseal (Analytic Endodontics/Kerr) or by lateral condensation technique using AH Plus sealer (epoxy type). The teeth were immersed in 2% methylene blue under vacuum. Then, they were longitudinally sectioned. The results showed that the association of Profile and Thermafil Plus provide the best results (p<0.05). In conclusion, the association of different rotary instrumentation techniques and different filling systems influenced the apical sealing.

AbstractThis case report describes the treatment of a tooth with necrotic pulp and open apex (maxillary left central incisor). In this conventional multiple-visit apexification with calcium hydroxide was replaced with a simple two step apical barrier techinique using MTA. The treatment involved mild debridement of the dentinal walls with K files and repeated irrigation with sodium hypochlorite solution, followed by calcium hydroxide dressing for 1 week and lastly creating an apical plug with MTA. The objective of the treatment was to provide an apical stop for the root canal filling material.

Background: This clinical trial aimed to compare the effects of bioceramic sealer and resin-based sealer on the incidence and intensity of postoperative pain. Methods: Patients with anterior teeth or premolars requiring root canal treatment were assigned to group 1 (n = 51). Those with molars requiring treatment were assigned to group 2 (n = 57). In groups 1En and 2En, root canals were obturated with Endoseal MTA using the single-cone technique. In groups 1AH and 2AH, the sealer used was AH Plus with the continuous wave technique. On the day of canal filling, each patient was instructed to indicate their pain intensity over the 7 day postoperative period, at rest and, while biting, using a visual analog scale. Results: There was no significant difference in the incidence or intensity of postoperative pain between the Endoseal MTA and AH Plus groups during the 7 day postoperative period (p > 0.05). Less time was needed to seal the root canals with Endoseal MTA, especially in group 2 (p < 0.05). Conclusions: Endoseal MTA and AH Plus had similar effects on the incidence and intensity of postoperative pain. The obturation time was shorter when using Endoseal MTA compared to AH Plus.
