Abstract
The link between periodontitis and systemic diseases has increasingly become a focus of research in recent years. In this context, it is reasonable-especially in vulnerable patient groups-to minimize bacteremia during periodontal treatment. The aim of the present in vivo feasibility study was to investigate the possibility of laser-based bacteremia prevention. Patients with stage III, grade B generalized periodontitis were therefore treated in a split-mouth design either with prior 445 nm laser irradiation before nonsurgical periodontal therapy or without. During the treatments, clinical (periodontal measures, pain sensation, and body temperature), microbiological (sulcus samples and blood cultures before, 25 min after the start, and 10 min after the end of treatment), and immunological parameters (CRP, IL-6, and TNF-α) were obtained. It was shown that periodontal treatment-related bacteremia was detectable in both patients with the study design used. The species isolated were Schaalia georgiae, Granulicatella adiacens, and Parvimonas micra. The immunological parameters increased only slightly and occasionally. In the laser-assisted treatments, all blood cultures remained negative, demonstrating treatment-related bacteremia prevention. Within the limitations of this feasibility study, it can be concluded that prior laser disinfection can reduce bacteremia risk during periodontal therapy. Follow-up studies with larger patient numbers are needed to further investigate this effect, using the study design presented here.

Abstract
Background Chronic periodontitis is the most common dental disease reported globally as well as in India. Periodontal pathogens are usually seen in samples of gingival tissues, crevicular blood, GCF (gingival crevicular fluid), and dental plaque. Apart from the conventional mechanical treatment, laser disinfection is a recent advancement that change shows greater efficacy in reducing the disease progression and changing the bacterial flora. Aim The present study aimed to assess the Immediate response of diode laser on the microbial load in subjects with chronic Periodontitis as assessed in saliva, crevicular blood, and GCF (gingival crevicular fluid) samples. Materials and Methods The study recruited 90 subjects with chronic periodontitis. For split-mouth fashion, the mouth, of each participant was divided into two halves and was divided into two groups randomly. Group I (test group) subjects underwent laser disinfection (970 ± 15 nm). Group II subjects served as controls and underwent saline irrigation. For all participants, crevicular blood, saliva, and GCF samples were collected before and immediately following disinfection for microbial analysis. Results Microbial load reduction was seen in both groups following treatment. However, a significantly higher reduction was seen in the test group with laser disinfection. Compared to the crevicular blood sample, a greater reduction was seen in saliva and GCF samples. Conclusion The present study concludes that Diode Laser (970 ± 15 nm) application shows an immediate reduction of the bacterial load in subjects with chronic periodontitis.

Comparative Evaluation of Conventional Therapy With and Without Use of Diode Laser (DL) in the Treatment of Chronic Generalized Periodontitis: A Clinico-Microbiological Study. Cureus 2023; 15:e35720. [PMID: 37016638 PMCID: PMC10066870 DOI: 10.7759/cureus.35720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 03/01/2023] [Indexed: 03/06/2023] Open
Abstract
INTRODUCTION Chronic periodontitis is caused by a persistent and expanding interaction between a subgingival pathogenic microbial biofilm and the host immune system. The host's reaction to local factors directly influences the inflammation and bone loss that result from these interactions. Depending on variables like the severity of soft tissue damage and bone loss, treatment options can range from nonsurgical to surgical. Nonsurgical treatments are frequently used as the first-line therapy for inflammatory periodontal disease. In fact, careful scaling and root planing (SRP), a nonsurgical treatment, has been extensively studied and shown to be a highly predictable and effective therapy. According to recent research, using a diode laser (DL) in addition to standard SRP may reduce bacterial count and reinfection significantly. Laser therapy could be helpful in treating periodontal disease because of its antibacterial and detoxifying effects. The goal of this study is to investigate whether using a DL in addition to conventional flap surgery enhances patient outcomes for those with chronic generalized periodontitis. MATERIALS AND METHODS The 12 participants in this split-mouth trial with chronic generalized periodontitis were the main subject of the study. All of them had probing pocket depths (PPDs) of at least 5 mm after the initial phase of treatment. Each patient in the control group (Group A) and test group (Group B) received a conventional flap after being randomly assigned to one of the groups. Group B underwent a conventional flap with a 980 nm DL, whereas those in Group A did not receive any DL therapy. Periodontal pockets in both groups were evaluated at baseline, 45 days, and 90 days after a sub-gingival plaque test. Quantitative real-time polymerase chain reactions were used to examine the presence of red complex organisms in the plaque sample. RESULTS From baseline to 45 days and then to 90 days, clinical attachment loss (CAL), plaque index (PI), and gingival index (GI) all significantly decreased. However, results from 45 days to 90 days were statistically non-significant, with the exception of the GI, where Group B results were significantly different from Group A results from 45 days to 90 days. On the other hand, when a DL was combined with conventional flap surgery in the test group, the quantity of red complex bacteria was significantly decreased. CONCLUSION When DL was used in conjunction with conventional flap surgery, the results showed that CAL, PI, and GI were all significantly reduced while the quantity of red complex bacteria was also significantly decreased.

Abstract
Background Due to the limitations of scaling and root planing (SRP) in chronic periodontitis (CP) management, research has been focused on utilising additional therapies to enhance conventional treatment methods. The present systematic review is aimed to appraise the accessible scientific evidence of in vivo human studies to establish the effectiveness of adjunctive diode (λ 808- λ 980nm) laser treatment to SRP in CP. Methodology This systematic review was conducted following the PRISMA statement guidelines. The review protocol is registered in PROSPERO (CRD 42021227695). The search strategies were based on structured electronic and manual (with appropriate keywords) and were conducted to collect the applicable published data on RCTs studies (in vivo human), spanning over ten years between August 2010 and August 2020. The articles were selected to address the following research focus question: “Does diode laser (λ 808- λ 980nm) therapy have superior effects as an adjunct to SPR, compared to SRP alone, in terms of clinical or microbiological or immunological profiles in the management of CP?” Results Fifteen articles met the eligibility criteria and are included in this review. A wide range of discrepancies and inconsistencies were shown in the outcomes of the laser and SPR treatment modality, compared to SRP alone. The data on standardised study protocol, optimal laser parameters and outcome measurements were inconclusive, and a high risk of bias in the majority of the studies observed, which are crucial in establishing a homogenous and reproducible protocol. Conclusion In light of the confined evidence-based data and critical evaluation of this systematic review, the efficacy of adjunctive diode laser treatment ranging between 808 and 980nm to SRP remains debatable. The observational quality of the present systematic review was emphasised after scrutinising the available data, and an attempt to propose a laser protocol for future RCTs consideration was a great challenge due to an absence of clear and standardised recommendations in delivering a reliable laser protocol which can be replicable by future investigators. RCTs with robust methodology are warranted.

Abstract
Photobiomodulation therapy (PBMT) has anti-inflammatory, analgesic and regenerative properties. This systematic review aimed to critically appraise the published data of in vivo human randomized clinical trials (RCTs), and present a comprehensive overview of the efficacy of PBMT, as an adjunct to the nonsurgical periodontal therapy (NSPT) in the management of periodontitis. The systematic review protocol is registered in the Prospective Register Of Systematic Reviews (PROSPERO) (www.crd.york.ac.uk/PROSPERO/; ref CRD 42020169108). With the help of the appropriate key words, structured electronic and manual search strategies were applied to gather the relevant published data on in vivo human RCTs based on this topic. Seventeen papers that met the eligibility criteria were included in this review and subjected to a qualitative assessment. Current evidence lacks adequate information regarding the photobiomodulation (PBM) dosimetry, which is fundamental in establishing a standardized and replicable protocol for future researches. Furthermore, substantial discrepancies in the study methodology and a high risk of bias, arising from the majority of the included papers, abet to the inferior quality of these studies. Ultimately, there is an urgent necessity to conduct further well-designed RCTs in order to determine the effectiveness of PBMT, if any, by taking into consideration the abovementioned confounding factors.

Evaluation of the Effectiveness of the Use of the Diode Laser in the Reduction of the Volume of the Edematous Gingival Tissue after Causal Therapy. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E6192. [PMID: 32859022 PMCID: PMC7503832 DOI: 10.3390/ijerph17176192] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 08/21/2020] [Accepted: 08/24/2020] [Indexed: 01/19/2023]
Abstract
AIM The aim of this study was to evaluate and compare two different techniques for the treatment of plaque-induced gingivitis, demonstrating whether the causal therapy supported by diode laser can allow a resolution of the edema caused by gingivitis in less time compared to the single traditional causal therapy. MATERIALS AND METHODS Twenty-five patients between 20 and 60 years of age with a specific diagnosis of gingivitis were evaluated at the CLID-HSR oral hygiene department. Once the clinical parameters (bleeding index, plaque index, recession, and clinical attack level) were recorded, each of them was subjected to a professional oral hygiene session and instructed in correct home hygiene procedures. Through a split-mouth protocol for each individual patient, hemi-arches were treated by simple randomization to be treated with causal therapy supported by the action of the diode laser (experimental therapy) and which with traditional causal therapy (control therapy). A first intraoral scan was performed before therapy (T0), which was repeated 20 min after rinsing with CHX. The intraoral scans were repeated at a control 7 (T1) and 14 days (T2) after the session. For each intraoral scan, a volumetric value was calculated, proportional to the edema of the gingival tissues, using special digital software. The operator who carried out the volumetric measurements on the software was not aware of the therapy implemented on each half-arch. The operator who carried out the statistical analysis was not aware of the therapy applied to each group. The collected data were statistically compared in order to detect any differences between the volumetric variations between the two therapy groups and within the therapy groups over time. After evaluating the distribution of data by means of the Kolmogorov-Smirnov statistical test, the appropriate nonparametric tests were chosen to carry out the statistical comparisons. RESULTS Based on the analysis of the gingival-periodontal health parameters and the volumetric value of the treated areas, no statistically significant differences were detected between the areas treated with the adjuvant action of the diode laser compared to those treated with causal therapy alone. CONCLUSIONS With the limitations of this study, in accordance with the statistical results obtained, diode laser therapy does not allow a faster resolution of gingival edema compared to traditional therapy; the two treatment techniques for plaque-induced gingivitis, therefore, have the same efficacy.

Abstract
(Part 2 of this article can be located at www.liebertpub.com/doi/10.1089/photob.2019.4731.) Objective: Finding evidence-based treatment strategies for low-level light therapy (LLLT) and the correct incorporation of these treatment methods in the clinical practice of periodontics. Background: Photobiomodulation has been shown to have biostimulatory, anti-inflammatory and analgesic effects that can be beneficial in periodontal and dental implant treatment procedures. Methods: In this review we have addressed some clinical questions regarding the potential clinical application of low-level light irradiation and its photobiomodulatory effects in periodontology and implantology. The literature was searched for in vivo (animal or clinical) articles written in English in four electronic databases of PubMed, Scopus, Google Scholar, and Cochrane Library until April 2019. Only studies with low irradiation doses without any thermal effects used only for their photobiomodulatory purposes were included. Results: We were able to find relevant studies for all of our questions, and positive effects for the application of light therapy were reported in most of the studies. However, there is still great deal of heterogeneity in terms of study designs and most importantly in light irradiation devices and the parameters used. Owing to this issue it was not possible to reach specific evidence-based irradiation protocols for the questions addressed in this review. Conclusions: Based on our search results, an obvious positive effect of LLLT on stimulation of healing of periodontal soft and hard tissues and reduction of inflammation can be seen. Future well-designed randomized control studies with the same irradiation settings and systematic reviews evaluating the studies found on the questions mentioned are necessary to reach evidence-based recommendations.

Abstract
Introduction: Free gingival grafting is among the most foreseeing procedures for increasing the zone of keratinized attached gingiva and enhancing soft tissue around the teeth and dental implants. Nowadays low-level laser therapy (LLLT) is a promising approach in providing patients with more pleasing results in terms of esthetics and comfort. This study aims to investigate the effects of LLLT on gingival recessions treated with free gingival graft (FGG). Methods: This case series was conducted on 12 individuals requiring a bilateral gingival graft in the mandibular region. There was a 30-day interval between the two operations. The test side was selected randomly and irradiated by a low-level laser (LLL) just before surgery. The patients did not know which side was irradiated. LLLT was applied to the donors' as well as recipients' site immediately after the operation and 48 hours later. The patients were instructed to record their post-operative pain in a visual analogue scale (VAS) 3 and 24 hours and 7 days after the surgical procedure. The clinical photographs were taken immediately and 30 days after surgical treatment were graded by three experienced periodontists for color matching to adjacent tissues. Results: Ten individuals could finish the study. The test group presented significantly better shade matching and wound healing at the palatal donor site on days 7, 14 and 21. There was a significant reduction in post-operative pain after 24 hours (P = 0.007). No statistically significant difference was found between both groups in terms of clinical periodontal indices. Conclusion: LLLT could reduce post-operative pain 24 hours after surgical treatment. Furthermore, the application of LLLT could improve the donors' site healing and the recipients' site color matching.

Abstract
Laser irradiation has numerous favorable characteristics, such as ablation or vaporization, hemostasis, biostimulation (photobiomodulation) and microbial inhibition and destruction, which induce various beneficial therapeutic effects and biological responses. Therefore, the use of lasers is considered effective and suitable for treating a variety of inflammatory and infectious oral conditions. The CO2 , neodymium-doped yttrium-aluminium-garnet (Nd:YAG) and diode lasers have mainly been used for periodontal soft-tissue management. With development of the erbium-doped yttrium-aluminium-garnet (Er:YAG) and erbium, chromium-doped yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers, which can be applied not only on soft tissues but also on dental hard tissues, the application of lasers dramatically expanded from periodontal soft-tissue management to hard-tissue treatment. Currently, various periodontal tissues (such as gingiva, tooth roots and bone tissue), as well as titanium implant surfaces, can be treated with lasers, and a variety of dental laser systems are being employed for the management of periodontal and peri-implant diseases. In periodontics, mechanical therapy has conventionally been the mainstream of treatment; however, complete bacterial eradication and/or optimal wound healing may not be necessarily achieved with conventional mechanical therapy alone. Consequently, in addition to chemotherapy consisting of antibiotics and anti-inflammatory agents, phototherapy using lasers and light-emitting diodes has been gradually integrated with mechanical therapy to enhance subsequent wound healing by achieving thorough debridement, decontamination and tissue stimulation. With increasing evidence of benefits, therapies with low- and high-level lasers play an important role in wound healing/tissue regeneration in the treatment of periodontal and peri-implant diseases. This article discusses the outcomes of laser therapy in soft-tissue management, periodontal nonsurgical and surgical treatment, osseous surgery and peri-implant treatment, focusing on postoperative wound healing of periodontal and peri-implant tissues, based on scientific evidence from currently available basic and clinical studies, as well as on case reports.

Abstract
Lasers have various periodontal applications including calculus removal (Er: YAG, Er, Cr: YSGG lasers); soft tissue excision, incision and ablation; decontamination of root and implant surfaces; biostimulation; bacteria reduction; and osseous surgery. This paper reviews some of the major opportunities for using lasers in periodontal and implant specialty practices. The literature relating to the use of lasers for removal of the pocket epithelium, root conditioning, bacterial reduction and decontamination of infected implant surfaces is discussed, and a summary of the advantages and disadvantages of using lasers for periodontal treatment is provided.

Abstract
This meta-analysis was conducted to investigate the efficacy and safety of antimicrobial photodynamic therapy used alone or adjunctive to scaling root planing in patients with chronic periodontitis. The meta-analysis was conducted according to the QUOROM statement and recommendations of the Cochrane Collaboration. An extensive literature search was performed on seven databases, followed by a manual search. Weighted mean differences and 95% confidence intervals were calculated for clinical attachment level, probing depth and gingival recession. The I(2) test was used for inter-study heterogeneity; visual asymmetry inspection of the funnel plot, Egger's regression test and the trim-and-fill method were used to investigate publication bias. At 3 months, significant differences in clinical attachment level (p = 0.006) and probing depth reduction (p = 0.02) were observed for scaling root planing with antimicrobial photodynamic therapy, while no significant differences were retrieved for antimicrobial photodynamic therapy used alone; at 6 months no significant differences were observed for any investigated outcome. Neither heterogeneity nor publication bias was detected. The use of antimicrobial photodynamic therapy adjunctive to conventional treatment provides short-term benefits, but microbiological outcomes are contradictory. There is no evidence of effectiveness for the use of antimicrobial photodynamic therapy as alternative to scaling root planing. Long-term randomized controlled clinical trials reporting data on microbiological changes and costs are needed to support the long-term efficacy of adjunctive antimicrobial photodynamic therapy and the reliability of antimicrobial photodynamic therapy as alternative treatment to scaling root planing.

Abstract
Transient bacteremia from oral cavity related to oral anaerobic bacteria may occur as a result of dental healthcare procedures but also as a result of daily gestures involving the gums (chewing and oral hygiene). The risk of presenting a transient bacteremia is related to oral cavity bacterial load and to the severity of inflammation in the oral cavity. Although bacteremia is transient, in patients with immunodeficiency or comorbidity, this bacteremia may cause extra-oral infections. The bacteremia rate and the identified bacteria vary from one study to the next, depending on the method used to isolate and identify bacteria. Nevertheless, the risk for bacteremia is determined by the infectious and inflammatory conditions of each patient.

Abstract
BACKGROUND AND OBJECTIVE In recent years, there has been a growing interest in the use of dental lasers for treatment of periodontal diseases. The purpose of this short-term clinical trial was to evaluate the effects of a combination of photodynamic therapy with low-level laser therapy as an adjunct to nonsurgical treatment of chronic periodontitis. MATERIAL AND METHODS Twenty-four nonsmoking adults with untreated chronic periodontitis were randomly assigned in a split-mouth design to receive scaling and root debridement with or without one course of adjunctive photodynamic therapy and low-level laser therapy within 5 d. Plaque, bleeding on probing, probing depth and gingival recession were recorded at baseline, 1 and 3 mo after the treatment. Gingival crevicular fluid was collected for assay of interleukin-1β levels at baseline, 1 wk and 1 mo. RESULTS The test teeth achieved greater reductions in the percentage of sites with bleeding on probing and in mean probing depth at 1 mo compared with the control teeth (p < 0.05). A significant decrease in gingival crevicular fluid volume was observed in both groups at 1 wk (p < 0.001), with a further decrease at 1 mo in the test sites (p < 0.05). The test sites showed a greater reduction of interleukin-1β levels in gingival crevicular fluid at 1 wk than the control sites (p < 0.05). No significant differences in periodontal parameters were found between the test and control teeth at 3 mo. CONCLUSIONS The present study suggests that a combined course of photodynamic therapy with low-level laser therapy could be a beneficial adjunct to nonsurgical treatment of chronic periodontitis on a short-term basis. Further studies are required to assess the long-term effectiveness of the combination of photodynamic therapy with low-level laser therapy as an adjunct in nonsurgical treatment of periodontitis.

Abstract
BACKGROUND The objective of this study was to systematically review the evidence on the effectiveness of laser therapy as an adjunct to non-surgical periodontal treatment in adults with chronic periodontitis. METHODS A search was conducted for randomized controlled trials comparing the outcome of periodontitis with laser as an adjunct to scaling and root planing in the treatment of chronic periodontal disease. The electronic databases, PubMed and Cochrane Central Register of Controlled Trials, were used as data sources. Screening, data abstraction, and quality assessment were conducted independently by three reviewers (MK, HJ, and CDL). The primary outcome measures evaluated were changes in clinical attachment level, probing depth, and bleeding on probing. RESULTS The search resulted in 25 abstracts; four randomized controlled clinical trials were included. Four different laser methods were used; consequently, it was impossible to conduct a quantitative data synthesis leading to a meta-analysis. All studies included a limited number of subjects. CONCLUSIONS No consistent evidence supports the efficacy of laser treatment as an adjunct to non-surgical periodontal treatment in adults with chronic periodontitis. More randomized controlled clinical trials are needed.

Abstract
SUMMARY The human gingival niche is a unique microbial habitat. In this habitat, biofilm organisms exist in harmony, attached to either enamel or cemental surfaces of the tooth as well as to the crevicular epithelium, subjacent to a rich vascular plexus underneath. Due to this extraordinary anatomical juxtaposition, plaque biofilm bacteria have a ready portal of ingress into the systemic circulation in both health and disease. Yet the frequency, magnitude, and etiology of bacteremias due to oral origin and the consequent end organ infections are not clear and have not recently been evaluated. In this comprehensive review, we address the available literature on triggering events, incidence, and diversity of odontogenic bacteremias. The nature of the infective agents and end organ infections (other than endocarditis) is also described, with an emphasis on the challenge of establishing the link between odontogenic infections and related systemic, focal infections.
