Abstract
PURPOSE This systematic review provides an overview of the main chemical and morphological alterations generated on dentin by different high-power lasers' irradiation. METHODS The review was registered in PROSPERO (CRD42023394164) and PRISMA guidelines were followed. The search strategy was conducted on MEDLINE (PubMed), Embase (Elsevier), and Web of Science (Clarivate) databases. The eligibility criteria were established according to the PICOS strategy, focusing on in vitro and ex vivo studies that assessed the chemical and morphological changes in dentin using five high-power lasers: Nd:YAG (1064 nm), Er:YAG (2940 nm), Er, Cr:YSGG (2780 nm), diode (980 nm), and CO2 (10,600 nm). Publication range was from 2010 to 2022. Data was summarized in tables and risk of bias was assessed by QUIN tool. RESULTS The search resulted in 2255 matches and 57 studies composed the sample. The methods most used to assess the outcomes were scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and Raman. The studies presented "medium" and "low" risk of bias. The laser prevalently identified was the Er:YAG laser, associated with dentin ablation, absence of smear layer, and exposed tubules. The Nd:YAG laser generated vitreous surface and thermal damage, such as carbonization and cracks. The other lasers caused an irregular surface and no adverse thermal effects. Regarding the chemical structure, only the Er,Cr:YSGG laser caused collagen matrix reduction. The effects found were more intense with higher dosimetry. CONCLUSION Evidence available indicates that the irradiation of dentin with high-power lasers are related to morphological outcomes favorable to adhesive restorative procedures, with minimal changes in collagen matrix and mineral content. However, those observations should be carried carefully by clinicians and more clinical trials regarding the association of high-power laser irradiation and restorative procedure longevity are needed.

A systematic review of animal studies. Restor Dent Endod 2023; 48:e24. [PMID: 37675444 PMCID: PMC10477425 DOI: 10.5395/rde.2023.48.e24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Revised: 03/26/2023] [Accepted: 03/29/2023] [Indexed: 09/08/2023] Open
Abstract
This review aimed to answer the following question "Does photobiomodulation treatment of the root surface decrease the occurrence of root resorption in reimplanted teeth?" Electronic searches were performed in the MEDLINE/PubMed, Cochrane Library, Scopus, Web of Science, Embase, and Grey Literature Report databases. Risk of bias was evaluated using SYRCLE Risk of Bias tool. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool was used to assess the certainty of evidence. In total, 6 studies were included. Five studies reported a reduced occurrence of root resorption in teeth that received photobiomodulation treatment of the root surface prior to replantation. Only 1 study reported contradictory results. The photobiomodulation parameters varied widely among studies. GRADE assessment showed a low certainty of evidence. It can be inferred that photobiomodulation treatment of the root surface prior to replantation of teeth can reduce the occurrence of root resorption. Nonetheless, further clinical studies are needed. Trial Registration PROSPERO Identifier: CRD42022349891.

Abstract
Resumo Introdução A busca por protocolos efetivos para reduzir a incidência de reabsorções radiculares e favorecer a reparação do ligamento periodontal perdido ainda representa um grande desafio, tendo em vista o prognóstico desfavorável dos reimplantes dentais tardios. Objetivo Avaliar, por meio da análise histológica, os efeitos do laser de alta potência e da fotobiomodulação na ocorrência de reabsorção radicular e no reparo periodontal, em dentes reimplantados tardiamente. Material e método Foram utilizados 50 incisivos centrais direitos de ratos Wistar. Após a extração, os espécimes foram divididos em cinco grupos (n = 10): G1 (controle positivo): reimplante imediato; G2 (controle negativo): reimplante tardio (RT): espécimes mantidos em ambiente seco por 60 minutos, sem tratamento adicional; G3: RT associado ao tratamento da superfície radicular com laser diodo de alta potência (810 nm, 1.5 W); G4: RT + superfícies radiculares e feridas alveolares tratadas com fotobiomodulação (laser diodo 660 nm, 30 mW e 780 nm, 40 mW, respectivamente); G5: RT + superfícies radiculares irradiadas com laser de alta e alvéolos com fotobiomodulação, nos mesmos parâmetros que G3 e G4, respectivamente. Após 60 dias, os animais foram eutanasiados. Os espécimes foram processados para análise histológica. Resultado G3 e G5 apresentaram as menores médias de scores com relação à ocorrência de reabsorções radiculares e anquilose, quando comparados a G2 e G4 (Teste Kruskall-Wallis, p<0,05). Com relação ao reparo periodontal, todos os grupos experimentais (G3, G4 e G5) apresentaram médias de escores inferiores (Teste Kruskall-Wallis, p<0,05) comparadas ao G1 e semelhantes ao G2 (Teste Kruskall-Wallis, p>0,05). Conclusão O laser de alta potência, associado ou não à fotobiomodulação, diminuiu a ocorrência das reabsorções radiculares e da anquilose, e a fotobiomodulação não favoreceu o controle das reabsorções radiculares nem o reparo periodontal.

Abstract
AIM The search for effective protocols to reduce the incidence of root resorption and allow periodontal ligament repair is still challenging, given the unpredictable outcome of late tooth replantation. The aim of this study was to assess the effects of both high-power diode laser irradiation (DL) and basic fibroblast growth factor (FGF) on the periodontal healing of replanted teeth after extended extra-oral dry time. METHODS Maxillary incisors of 50 male rats were extracted and assigned to three experimental and two control groups (n = 10). DL: root surfaces treated with DL (810 nm, continuous mode, 1.0 W, 30 s), FGF: topical application of FGF gel to the root surface and in the alveolar wound, DL + FGF: DL and topical application of FGF gel, C+: no treatment after extraction and immediate replantation and C-: no treatment after extraction and replantation after 60 min. In the experimental groups, the specimens were kept dry for 60 min, the pulps were removed and the canals were filled with calcium hydroxide paste prior to tooth replantation. The animals were euthanized after 60 days. The specimens were processed for radiographic, histological and immunohistochemical analyses. RESULTS The radiographic analysis showed fewer resorptive areas in DL + FGF (P < 0.05). The histological and immunohistochemical analyses showed that the DL group had lower mean values of ankylosis, replacement and inflammatory resorption when compared to C-, not differing statistically from C+. DL + FGF produced significantly more collagen fibers (type I and type III) than C-, not differing from C+ in the case of type I fibers (P < 0.05). CONCLUSIONS DL, with or without FGF, reduced the occurrence of external root resorption and ankylosis. Periodontal healing was favored and some fiber reinsertion occurred only when FGF was used.

Abstract
BACKGROUND/AIM Tooth replantation is the optimal treatment in cases of avulsion. However, its success is limited due to the occurrence of external root resorption. The aim of this study was to assess the effect of laser photobiomodulation (LPBM) at λ808 nm and λ660 nm and of storage media on the periodontal repair process of replanted teeth in rats. MATERIAL AND METHODS Sixty maxillary right incisors were extracted from sixty Wistar rats and randomly assigned to six groups (n = 10). Groups consisted of 10 teeth stored in paper napkins (PN), whole milk (WM), and soy milk (SM), for 45 min; and PNL, WML and SML, in which teeth were stored in the same storage media, but the root surface and the alveolus were treated with LPBM at λ808 nm before replantation, and the buccal and palatal mucosa of the alveolus were treated with LPBM at λ660 nm after replantation. Five rats from each group were euthanized after 15 or 30 days. The right hemimaxilla including the replanted incisor was removed and processed for histomorphometric analysis to assess root resorption areas, replacement root resorption, perimeter with ankylosis and periodontal repair, and areas of type I and III collagen deposition, using the ImageJ 1.50b software. Data were analyzed statistically by anova followed by Tukey's multiple comparison test (α = 5%). RESULTS WM and SM showed smaller root resorption areas and higher collagen deposition in both experimental periods, and SM showed the largest perimeter of periodontal repair. LPBM reduced the occurrence of root resorption only in the PNL group, both at 15 and 30 days, and increased the perimeter of periodontal repair in all groups at 30 days. There was higher collagen deposition in the irradiated groups regardless of the experimental period. CONCLUSIONS The LPBM protocol at λ808 nm and λ660 nm as well as whole milk and soy milk favored the periodontal repair process of replanted teeth in rats.

Abstract
Objectives This study investigated cellular attachment to 6 root-end filling materials as a
measure of the biocompatibility of the materials. Material and Methods Class I retrograde cavities were prepared in root slices and these cavities were
filled with the test materials, and incubated with Balb/C 3T3 fibroblasts for 24
h. Root slices with the cavities left empty served as the controls. The root
slices were then processed for scanning electron microscopy, and were viewed to
assess the quality of cellular attachment by observing the shape of cells, spread,
and membrane outline. Results The best cellular attachment was observed at MTA and Geristore surfaces: cells
exhibited characteristic elongated fibroblastic morphology, with projections of
lamellipodia, filopodia, blebs, and microvilli from their surfaces, reflecting
good attachment to the material. Fibroblasts attached poorly to the surfaces of
IRM, Super EBA, KetacFil and Retroplast. Furthermore, the cells did not attach
well to the tooth structure next to IRM and Super EBA. Conclusions The present study demonstrated a variation in cellular attachment to different
root-end filling materials with the best cellular attachment to the surfaces of
MTA and Geristore. IRM and Super EBA, Ketac Fil and Retroplast rendered poor
attachment.

Management of Root Perforations Using MTA with or without Er:YAG Laser Irradiation: An In Vitro Study. Int J Dent 2012; 2012:628375. [PMID: 22888350 PMCID: PMC3408720 DOI: 10.1155/2012/628375] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2012] [Revised: 04/09/2012] [Accepted: 06/11/2012] [Indexed: 11/18/2022] Open
Abstract
The aim of this in vitro study is to compare the microleakage of a root perforation sealed with MTA (mineral trioxide aggregate) (group M) to that sealed with MTA following Er:YAG laser irradiation (group ML). Forty-two recently extracted human monoroot teeth were used. Two cavities were prepared on each root surface. Randomly, on each root, the exposed dentine of one cavity was irradiated prior to MTA filling using an Er:YAG laser with the following settings: 200 mJ/pulses under an air water spray, 10 Hz, pulse duration of 50 μsec, and 0.7 mm beam diameter. All cavities were then sealed with MTA. submitted to thermocycling and immersed in 2% methylene blue dye solution for 12 h. The penetration of methylene blue in the microleakage of cavity was observed and recorded. The mean value dye penetration in cavities sealed with MTA following Er:YAG laser irradiation (23.91 ± 14.63%) was lower than that of unlased cavities sealed only with MTA (25.17 ± 17.53%). No significant difference was noted. The use of an Er:YAG laser beam for dentinal conditioning prior to MTA filling of perforated roots did not decrease significantly the microleakage of MTA sealing when compared to the conventional use of MTA filling.
