Abstract

Background: Minimally invasive endodontics is recommended for young, immature teeth to preserve healthy pulp and dentin tissue.

Objectives: The aim of the study was to examine the cold sensitivity of immature teeth that received photobiomodulation (PBM) after vital pulp therapy (VPT).

Material and methods: The study followed the STROBE guidelines and included 123 healthy patients aged 8-13. The immature teeth (incisors, premolars and molars) that qualified for VPT received the bioceramic material - Biodentine. In this experiment, teeth were treated immediately and at 24 h post-VPT with a 635-nm diode laser using a power of 100 mW, a power density of 200 mW/cm2 and a total energy of 4 J (PBM group, n = 43), while those not treated were the control group (n = 43). The tooth sensitivity to cold was measured using a visual analogue scale (VAS) before and at 6 h, 1 day, 7, 30, and 90 days after treatment. The predictor variable was PBM skills regarding the ability to decrease cold sensitivity after VPT. The primary endpoint was the time to reverse hypersensitivity to cold, and the secondary endpoint was the occurrence of possible side effects. The Mann-Whitney U test, Friedman test along with Dunn's post hoc test, and the χ2 test were used to investigate tooth sensitivity.

Results: Eighty-six immature permanent teeth of 86 children were included in the study. It was shown that the difference was significant for sensitivity to a cold stimulus between the groups at 6 h, 24 h, 7 days, and 30 days, but no difference was found preoperatively and at 90 days (6 h, 24 h, 7 days, and 30 days, p < 0.001, and 90 days, p = 0.079). However, patients in both groups reported a decrease in discomfort provoked by cold stimuli throughout the follow-up period.

Conclusions: Photobiomodulation decreased postoperative sensitivity and was more acceptable for patients. Further randomized clinical studies with placebo-controlled groups are needed.

光生物调制对未成熟牙齿激光辅助活髓治疗术后不适的评估:一项初步回顾性研究。
背景:建议对年轻、未成熟的牙齿进行微创根管治疗,以保护健康的牙髓和牙本质组织。目的:本研究旨在检测活髓治疗(VPT)后接受光生物调制(PBM)的未成熟牙齿的冷敏感性。材料和方法:本研究遵循STROBE指南,包括123名8-13岁的健康患者。符合VPT条件的未成熟牙齿(门牙、前臼齿和臼齿)接受了生物陶瓷材料-生物牙本质。在该实验中,立即在VPT后24小时用635nm二极管激光治疗牙齿,使用100mW的功率、200mW/cm2的功率和4J的总能量(PBM组,n=43),而未治疗的是对照组(n=43)。在治疗前和治疗后6小时、1天、7天、30天和90天,使用视觉模拟评分(VAS)测量牙齿对寒冷的敏感性。预测变量是关于VPT后降低冷敏感性的PBM技能。主要终点是逆转对冷的超敏反应的时间,次要终点是可能出现的副作用。使用Mann-Whitney U检验、Friedman检验以及Dunn的post-hoc检验和χ2检验来研究牙齿敏感性。结果:86名儿童的86颗未成熟恒牙被纳入研究。研究表明,在6小时、24小时、7天和30天时,两组对冷刺激的敏感性有显著差异,但在术前和90天时没有发现差异(6小时、24-小时、7-天和-30天,p<0.001,90天,p=0.079)。然而,两组患者在整个随访期间都报告了冷刺激引起的不适感减少。结论:光生物调制降低了术后的敏感性,对患者来说更容易接受。需要对安慰剂对照组进行进一步的随机临床研究。

期刊介绍: Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly. Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff. Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj. Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker. The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition. In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus. Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
