“…An investigation comparing the combination of low‐power laser irradiation and direct pulp capping with ProRoot MTA to the traditional treatments of placing the capping material on the exposure site reported that laser irradiation did not improve pulp responses to ProRoot MTA in terms of hard tissue formation (continuity, morphology and thickness) and inflammatory reactions (type, intensity and extension), and histopathologic change in pulp tissue (necrosis, odontoblastic layer formation and calcification); however, the authors did not compare their results statistically (Bidar et al . ).…”

Mineral trioxide aggregate and other bioactive endodontic cements: an updated overview – part I: vital pulp therapy

2017

Mineral trioxide aggregate (MTA) is a bioactive endodontic cement (BEC) mainly comprised of calcium and silicate elements. The cement was introduced by Torabinejad in the 1990s and has been approved by the Food and Drug Administration to be used in the United States in 1997. A number of new BECs have also been introduced to the market, including BioAggregate, Biodentine, BioRoot RCS, calcium-enriched mixture cement, Endo-CPM, Endocem, EndoSequence, EndoBinder, EndoSeal MTA, iRoot, MicroMega MTA, MTA Bio, MTA Fillapex, MTA Plus, NeoMTA Plus, OrthoMTA, Quick-Set, RetroMTA, Tech Biosealer and TheraCal LC. It has been claimed that these materials have properties similar to those of MTA without its drawbacks. In this article, the chemical composition and the application of MTA and other BECs for vital pulp therapy (VPT), including indirect pulp cap, direct pulp cap, partial pulpotomy, pulpotomy and partial pulpectomy, have been reviewed and compared. Based on selected keywords, all papers regarding chemical composition and VPT applications of BECs had been reviewed. Most of the materials had calcium and silicate in their composition. Instead of referring to the cements based on their chemical compositions, we suggest the term 'bioactive endodontic cements (BECs)', which seems more appropriate for these materials because, in spite of differences in their chemical compositions, bioactivity is a common property for all of them. Numerous articles were found regarding use of BECs as VPT agents for indirect and direct pulp capping, partial pulpotomy and cervical pulpotomy. Most of these investigations used MTA for VPT. In most studies, newly introduced materials have been compared to MTA. Some of the BECs have shown promising results; however, the number of their studies compared to investigations on MTA is limited. Most studies had several methodological shortcomings. Future investigations with rigorous methods and materials are needed.

“…[10][11][12][13][14][15][16][17][18] Others revealed that the application of LLLT enhanced bone healing and mineralization in the sockets of rats exposed to diode laser radiation. [19][20][21][22][23] However, some studies found no additional benefits of using low-level lasers over the placebo in several conditions such as releasing pain after the extraction of primary 24 and permanent 25 teeth, reducing pain and swelling following third molar surgery, [26][27][28] improving pulp tissue healing after direct pulp capping in dogs, 29 and attenuating chronic orofacial pain in patients with temporomandibular dysfunction (TMD). 30 This randomized, double-blind controlled trial was conducted to investigate the efficacy of LLLT in relieving pain and accelerating the healing of the tooth socket after the extraction of lower molar teeth.…”

Introduction: This study aimed to determine the effect of low-level laser therapy (LLLT) on reducing complications following tooth extraction. Methods: This randomized clinical trial consisted of 40 subjects who underwent lower molar extraction. The patients were randomly assigned to 4 groups. Group 1 was irradiated with a 660 nm laser (200 mW, 30 seconds radiation to lingual, buccal and occlusal surfaces of the socket, 6 J/area). In group 2, an 810 nm laser was applied similar to group 1. In group 3, a combination of 660 and 810 nm lasers was used. The patients in group 4 served as a placebo group. LLLT was performed after 0.5-1 hour of extraction and 2 days later. The participants were asked to record pain degree using a visual analogue scale (VAS) over 7 days. The amount of wound healing was evaluated on the third and seventh days. Results: There was no significant difference in pain scores among the groups at any of the assessment intervals (P>0.05). The between-group differences in wound healing scores were small and insignificant (P>0.05). Conclusion: LLLT with 660 nm or 810 nm lasers or their combination had no greater effect than the placebo laser for reducing the complications of tooth extraction.

Objective The infrared rays is one of the treatments to relief of dental pain due to pulpitis or periodontitis. The ability of infrared to increase the pain threshold which make eliminating P substance on the inflammation area and inducing Aβ and Aδ fibers to activate γ-aminobutyrate (GABA) and neuropeptides to decrease the pain. Hence, reducing or eliminating dental pain. This study to get information about effectively distance between patients and infrared rays which can reduce or eliminate dental pain. Materials and Methods The explorative experimental research to determine the effectivity of the infrared rays’ distance: 45, 55, and 55 cm in reducing or eliminating dental pain. The material of infrared was tungsten with luminous light and the time for the lighting was 15 minutes. Statistical Analysis The data were obtained and analyzed using Wilcoxon’s signed rank test and Kruskal–Wallis test (α= 0.05). Results There were influenced of the infrared rays to reduce the dental pain as follow, distance 45 cm (p = 0.007), distance 55 cm (p = 0.026), and distance 65 cm (p = 0.007). The average scale reduction for distance 45 cm was 2.22 ± 0.83, the distance 55 cm was 3.44 ± 0.82, and the distance 65 cm was (1.78 ± 0.83). Therefore, according to Kruskal–Wallis test with p = 0.004 (p < 0.05) showed the significant difference between the scale to decrease of dental pain was the distance of 55. Conclusion Infrared rays located at a distance of 55 cm from patients might be more effective in relieving dental pain, compared with other distances tested.
