“…2 The endodontic treatment of primary teeth is truly challenging because of the anatomical complexities like accessory foramina in furcal areas and aberrant morphology of their root canals. 3 In addition to the accessory canals, exposure of dentinal tubules as a result of physiological root resorption can also lead to structural alterations and greater permeability of the root surface to various microbial toxins. 4,5 The bacterial profile of root canals of human teeth associated with necrotic pulp and periapical lesions is enormous as well as extensive.…”

“…Photodynamic therapy is a technique employed for root canal disinfection using a photosensitizer; that produces singlet oxygen out of molecular oxygen (3O2) and other free radicals when exposed to laser light which in turn causes damage to the bacterial membrane and its DNA. 3,23,24 The soft tissue dental Diode laser is a compact and portable device which is used in various areas of dentistry. The diode laser emits radiation within the visible (mostly 660 nm) and infrared (810 to 980 nm) range of the electromagnetic spectrum.…”

Comparative evaluation of the efficacy of chlorhexidine, sodium hypochlorite, the diode laser and saline in reducing the microbial count in primary teeth root canals -an in vivo study. Abstract Introduction:One of the primary goals of pulpectomy is to decrease the sum total of microorganisms and disinfect the tooth root canal system. To achieve this, mechanical preparation, irrigation, disinfection and obturation of the root canal is necessary. The present study was set out to evaluate the difference in the antibacterial efficacy of primary teeth root canals either irrigated with chlorhexidine, saline, and sodium hypochlorite or irradiated with a soft tissue diode laser (980 nm, Photon Plus, Zolar Tech & Mfg Co. Inc, Ontario, Canada). Methods: Sixty primary teeth of children requiring pulpectomy were divided into 4 groups of 15 each, group 1 (2% chlorhexidine), group 2 (1% sodium hypochlorite), group 3 (laser irradiation) and group 4 (saline). Pulp tissue was extirpated from the canals and the samples were collected using sterile absorbent paper points. After cleaning and shaping, the root canals of the teeth in each group were irrigated using sodium hypochlorite, chlorhexidine, and saline or were irradiated with the laser. The samples were obtained again and sent for microbiological examination. Results: The colony-forming unit (CFU) counts from pre-disinfection sample served as a baseline for comparisons throughout the study. The mean bacterial colony counts of all the isolated bacteria reduced after irrigation or irradiation. Intergroup comparisons showed no significant difference when groups 1, 2, and 3 were compared to each other (P > 0.05). However, a significant difference was seen when groups 1, 2, 3 were compared to group 4 (P < 0.05). Conclusion: Two percent chlorhexidine, 1% sodium hypochlorite and laser irradiation succeeded in reducing the root canal infection. Hence, diode laser irradiation may be a possible supplement to existing protocols for disinfecting the root canal system.

“…Preparation of curved root canals and those with anatomical variations, especially in primary molars, are among the main challenges encountered in pulpectomy [5]. Other factors such as differences in canal diameter [6], accessory foramina at the furcation site [7], isthmi, apical accessory canals, and ramifications [8] and exposure of dentinal tubules due to physiological resorption of the root can also lead to structural changes and greater permeability of the root surface to microbial toxins [9]. Such anatomical and morphological changes are more commonly seen in primary molar teeth [10].…”

Objectives. This study aimed to compare the antibacterial efficacy of cold atmospheric plasma (CAP), photodynamic therapy (PDT) with two photosensitizers (PSs), and diode laser for disinfection of primary mandibular second molar root canals infected with Enterococcus faecalis (E. faecalis). Materials and Methods. In this in vitro experimental study, 50 primary second primary molars underwent chemomechanical preparation of root canals. The root canals were then inoculated with E. faecalis. After 3 weeks of incubation, the teeth were randomly assigned to five groups of CAP, 940 nm diode laser, PDT with 445 nm laser and curcumin PS, PDT with 660 nm laser and methylene blue (MB) PS, and 2.5% sodium hypochlorite (NaOCl). Samples were collected from the vortexed root canals and cultured on agar, and the number of colonies was counted. Data were analyzed by one-way analysis of variance. Results. The percentage of reduction in bacterial count was significantly different among the study groups ( P < 0.001 ). The highest reduction in bacterial count was noted in 2.5% NaOCl and the lowest in 940 nm diode laser group. The difference in bacterial count reduction between 445 nm laser + curcumin and 660 nm laser + MB ( P = 0.989 ), and CAP and NaOCl ( P = 1.000 ) groups was not significant. Conclusion. CAP was found to be more effective than PDT and diode laser as an adjunct to mechanical root canal disinfection of primary molars for elimination of E. faecalis and can serve as an alternative to 2.5% NaOCl irrigation.
