“…However, this technique is difficult to be applied with conventional needle irrigation to avoid solution extrusion from the apical foramen (30) . These results were in agreement with a study that applied diode laser irrigation activation on maleic acid which is the main component of apple vinegar (38) .…”

Purpose: This study was designed as randomized control trial to assess the effect of laser activation versus EndoVac systems with 5% apple vinegar irrigant on smear layer removal from root canal wall using scanning electron microscope. Material and Methods: Thirty three single rooted teeth were selected and prepared using Universal ProTaper rotary files and irrigated using sodium hypochlorite. Samples were randomly alienated into three groups (11 samples each) in proportion to method of activation of apple vinegar which used as final irrigant: Group I: Laser activated irrigation using 810nm diode laser at 1.5 Watts power in pulsed mode, Group II: EndoVac system used according to manufacturer instruction, and Group III (Control group) irrigating needle was used for irrigation, the amount of irrigant and time of application were adjusted according to each irrigating method. Scanning electron microscopic analysis was performed to evaluate smear layer of each group at different root canal levels. Results:No significant difference between tested groups in coronal and middle thirds but there is significant difference in apical third and total. In apical third, there is statistically significant difference between laser activated and EndoVac compared to control group, while no significant difference was found between EndoVac system and laser activated group (P-value <0.05). Conclusion: This in-vitro study demonstrated that using of 810 nm diode laser activation and EndoVac system with apple vinegar are effective in removing smear layer compared to conventional irrigation, particularly at apical third of root canal system.

AIM: The aim of this study was to compare and evaluate the penetration depth of irrigant after using manual, passive ultrasonic, and diode laser–assisted irrigant activation technique. Materials and Methods: Ninety extracted single-rooted human mandibular premolars were selected ( N = 90). Teeth were decoronated and working length was standardized for 12 mm. Root canals were shaped using ProTaper Universal F3. Saline was used as an irrigant in between every successful instrumentation. After completion of chemomechanical preparation, root canals were filled with Rhodamine-B-labeled sodium hypochlorite (3%). Teeth samples were divided into three experimental groups. In Group 1 ( n = 30), manual irrigant activation was performed for 30 seconds with master cone gutta-percha (F3) in gentle up and down motion. In Group 2 ( n = 30), ultrasonic irrigant activation was performed using passive ultrasonic endo tips for 30 seconds. In Group 3 ( n = 30), laser activation was performed using diode laser for 30 seconds with 200-µm tips. Transverse sections were made at 2, 5, and 8 mm from the root apex and were observed under confocal laser scanning microscopy. Maximum penetration depth of irrigant was recorded and statistically analyzed. Result: In the all three groups, coronal third (sections at 8 mm from root apex) showed the highest penetration depth of irrigant. Laser activation (Group 3) showed the highest penetration depth in all the three sections when compared with manual and passive ultrasonic irrigant activation. One-way analysis of variance and post hoc test showed there were significantly high differences among all the three groups and also at all three levels ( P < 0.05). Conclusion: Diode laser–assisted irrigant activation technique had better penetration depth in all the three aspects of root dentin.

“…Deposition of peritubular dentin increases leading to the narrowing of the dentinal tubules and complete obliteration of others which has a direct effect on the efficacy of the irrigating solutions (1) . Laser irradiation can cause morphological and chemical alterations in dentin represented by the evaporation of the dentin organic matrix leaving pores and spaces (29) . Thus, wider dentinal tubules of young teeth with higher irrigation efficacy have more pores and spaces than those of older teeth.…”

Purpose:The purpose of this study was to evaluate the effect of diode laser-980nm on microhardness of young and old canal dentin after treatment with NaOCl, NaOCl/ EDTA and distilled water solutions. Material and Methods Forty-eight single rooted premolars were divided into three groups according to the chemical solutions used (16 each) (8 for young teeth <30 years old and 8 for old teeth >50 years old). Group I: irrigated with 5ml of 2.6% NaOCl activated with diode laser, group II: irrigated with 5ml of 2.6% NaOCl without laser activation followed by 5ml of 17% EDTA activated with diode laser and group III: irrigated with 5ml of distilled water activated with diode laser. Then microhardness was evaluated at coronal, middle, and apical thirds of each root canal. Results: In all young and old groups, the coronal third had the highest mean value, followed by the middle, and the apical third had the lowest mean value, with a statistically significant difference between thirds of the groups (p0.001<). There was a statistically significant difference between young and old teeth at all levels (coronal, middle, and apical) for each group (I, II, and III), with old teeth having a greater mean microhardness value than young teeth. Conclusion: Irradiation of NaOCl/EDTA solutions with 980-nm diode caused reduction in microhardness of young dentin more than old dentin, and NaOCl only or distilled water in all thirds of groups.
