The efficacy of diode laser and subgingival air polishing with erythritol in treatment of periodontitis (clinical and microbiological study). BMC Oral Health 2024; 24:763. [PMID: 38965550 PMCID: PMC11225135 DOI: 10.1186/s12903-024-04481-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 06/13/2024] [Indexed: 07/06/2024] Open
Abstract
BACKGROUND There is insufficient clinical and microbiological evidence to support the use of diode laser and air-polishing with erythritol as supplements to scaling and root planning(SRP). The aim of the current study is to evaluate the clinical and microbiologic efficacy of erythritol subgingival air polishing and diode laser in treatment of periodontitis. METHODS The study encompassed twenty-four individuals seeking periodontal therapy and diagnosed with stage I and stage II periodontitis. Eight patients simply underwent SRP. Eight more patients had SRP followed by erythritol subgingival air polishing, and eight patients had SRP followed by diode laser application. At baseline and six weeks, clinical periodontal parameters were measured, including Plaque Index (PI), Gingival Index (GI), periodontal Probing Depth (PPD), and Clinical Attachment Level (CAL). The bacterial count of Aggregatibacter actinomycetemcomitans(A.A), Porphyromonas gingivalis (P.G) was evaluated at different points of time. RESULTS The microbiological assessment revealed significant differences in the count of A.A. between the laser and erythritol groups immediately after treatment, indicating a potential impact on microbial levels. However, the microbial levels showed fluctuations over the subsequent weeks, without statistically significant differences. Plaque indices significantly decreased post-treatment in all groups, with no significant inter-group differences. Gingival indices decreased, and the laser group showed lower values than erythritol and control groups. PPD and CAL decreased significantly across all groups, with the laser group exhibiting the lowest values. CONCLUSION The supplementary use of diode laser and erythritol air polishing, alongside SRP, represents an expedited periodontal treatment modality. This approach leads to a reduction in bacteria and improvement in periodontal health. TRIAL REGISTRATION This clinical trial was registered on Clinical Trials.gov (Registration ID: NCT06209554) and released on 08/01/2024.

Abstract
OBJECTIVE The aim of this randomized controlled trial was to assess clinical and patient reported outcomes of subgingival instrumentation (SI) with adjunctive use of diode laser (DL) versus SI alone in the treatment of periodontitis. METHODS Participants requiring non-surgical periodontal treatment were randomly allocated into two treatment groups: SI with DL or SI alone. Clinical parameters [full mouth bleeding and plaque scores (FMBS and FMPS), probing pocket depth and clinical attachment level] were recorded at baseline, three and 6 months post-treatment. Visual analogue scale was used to evaluate postoperative participants' perception of pain, swelling, bleeding, bruising and root sensitivity. The impact of periodontal treatment on quality of life was assessed using the General Oral Health Assessment Index (GOHAI) at 6 months. RESULTS A total of 22 participants with stage III/IV periodontitis completed the 6-month follow-up. SI with or without DL resulted in statistically significant reduction in FMBS, FMPS, PPDs, and percentage of PPDs of ≥5 mm at 3- and 6-month follow-up visits (p = 0.001 to <0.001). The participants in SI/DL group had a greater reduction in the percentage of deep PPDs (≥5 mm) compared to those receiving SI alone, but statistically significant differences between the two groups were not observed (16.40 ± 9.57 vs. 32.50 ± 38.76 at 3 months and 7.20 ± 6.86 vs. 19.50 ± 35.06 at 6 months). The difference in the mean total GOHAI scores was not statistically significant at 6 months with total GOHAI scores of 7.25 ± 2.45 and 5.40 ± 3.06 for SI and SI/DL groups, respectively. CONCLUSION Within the limitations of this study, the use of DL as an adjunct to SI in the treatment of stage III/IV periodontitis did not produce significant additional improvement in clinical parameters or patient reported outcomes in the 6-month observation period.

Abstract
Advances in haematological therapies for people with complex or rare inherited bleeding disorders (IBD) have resulted in them living longer, retaining their natural teeth with greater expectations of function and aesthetics. Dental management strategies need to evolve to meet these challenges. Utilising low level laser diode therapy to reduce pre-operative inflammation to reduce the intraoperative and postoperative burden on haemostasis is described in a case series of 12 patients. For these individuals who previously required further medical management to support haemostasis or experienced such prolonged haemorrhage sufficient to warrant hospital admission, haemostasis was achieved in the dental surgery such that they were able to return home with no further medical intervention or overnight stays. Global inequities in accessing novel treatments for complex or rare IBD necessitates a comprehensive understanding of the local haemostatic agents available to dentists and the most commonly used agents and techniques are described including the use of single tooth anaesthesia (STA). STA is a computerised delivery mechanism that allows routine dental procedures that would previously have required block injections needing factor replacement therapy to be undertaken safely and effectively with no additional haemostatic intervention. The challenges of inhibitors in oral surgery are explained and discussed although more research and evidence is required to establish new treatment protocols. The importance of establishing good dental health in the quality of life of people with complex or rare IBD is highlighted with respect to the dental specific impact that more novel therapies may have on people with IBD.

Abstract
Class IV dental diode lasers have been introduced as a nonsurgical therapy for periodontal pockets in veterinary and human dentistry. This retrospective case series evaluates the use of Class IV dental diode laser therapy for abnormal periodontal pockets in a specialty veterinary dental practice. A hypothesis that the Class IV diode dental laser is a useful adjuvant modality in canine periodontal pocket therapy in the reduction of clinical pocket depth was made. This article discusses and demonstrates diode laser use in periodontal pocket therapy in a specialty veterinary dental practice and reviews the current literature. Inclusion in this study was limited to client-owned dogs with noted periodontal pocketing on any tooth type between 3 and 6 mm, which were treated with closed root planing (RP/C) and laser therapy who returned in 6 to 7 months for recheck of the pockets from the years 2017 to 2020. Twelve patients met the inclusion criteria. A total of 128 periodontal pockets were included in the study. Each periodontal pocket was a case receiving therapy. The mean periodontal pocket depth before the treatment is measured as 3.35 mm. The mean pocket depth of the periodontal pockets following treatment was 0.59 mm. The mean improvement in periodontal pocket depths after diode laser therapy when considering patient and tooth number using linear mixed-effects modeling was 2.63 mm (95% confidence interval [CI]: 1.81-3.46, P < .0001). No statistically significant results were observed for pocket type, as P values were greater than .05.

Abstract
BACKGROUND Periodontitis is a microbially induced disease destroying structures anchoring teeth to jaw bones. Although metronidazole in combination with spiramycin is the effective conventional treatment of stage III grade C periodontitis, it has several systemic side effects. Laser therapy is widely used nowadays as an adjunct to scaling and root planing (SRP) to modulate inflammatory host response and eradicate microbes, due to bactericidal and detoxifying effects. Since microbiological analysis is one of the diagnostic methods identifying periodontal risk; our research aimed to investigate the efficacy of intra-pocket application of diode laser (980 nm) versus antibiotic therapy in enhancing clinical and microbiological parameters in stage III grade C periodontitis. METHODS A randomized controlled clinical trial was conducted on fifty patients with stage III grade C periodontitis, divided equally into two groups. We managed test group by SRP with intra-pocket application of diode laser (980 nm) and the control group by SRP with systemic antibiotic administration (spiramycin and metronidazole). Then, we measured periodontal pocket depth (PPD) and clinical attachment loss (CAL) for both groups, before treatment (baseline), four and twelve weeks after. Moreover, we collected gingival crevicular fluid from both groups at baseline, four and twelve weeks after treatment and analyzed by real-time polymerase chain reaction to detect the relative count of Aggregatibacter actinomycetemcomitans and Porhyromonas gingivalis. RESULTS Compared to baseline, all assessed clinical and microbiological parameters attested improvement at the end of the study period in each group individually with no significant difference between the two studied groups. Although, at twelve weeks, flare up of bacterial levels was detected with systemic antibiotic administration. CONCLUSION Laser therapy can be considered as an effective treatment modality in stage III grade C periodontitis, avoiding the systemic antibiotic side effects and solving the recurrence problems due to bacterial resistance by long term usage.

Abstract
INTRODUCTION The primary goal of periodontal therapy is to arrest the inflammatory disease process which is done by non-surgical and surgical therapies in order to reduce the microorganisms. The outcome of periodontal therapy may not reveal the desired results owing to inaccessible areas for instrumentation, pathogenicity, resistance of the microorganisms, or even due to compromised host response to the treatment. Thus, adjunctive laser therapy has been proposed as a novel treatment modality in the treatment of periodontal disease. Aim: The aim of this study was to clinically evaluate the effect of a 980 nm diode laser (DEN10B; Wuhan Gigaa Optronics Technology Co., Ltd., Wuhan, China) therapy as an adjunct to scaling and root planing in patients with chronic periodontitis and type II diabetes. METHODS Twenty patients were divided into two groups in a split-mouth study design. Group I (Control) comprised mechanical debridement alone and Group II (test) comprised mechanical debridement followed by adjunctive laser therapy. The clinical parameters were recorded at baseline, six weeks, and three months, and the results were analyzed. RESULTS There was a significant improvement in gingival and plaque index in the test group. Though there was no significant improvement in probing pocket depth and clinical attachment, the results in the test group were superior relative to the control group. CONCLUSION Non-surgical periodontal therapy with adjunctive use of diode laser is effective in the management of generalized chronic periodontitis in patients with type II diabetes which led to a significant reduction in plaque score, gingival index score, probing pocket depth, and gain in clinical attachment level.

Abstract
OBJECTIVES The aim of this study was to investigate whether the use of adjunctive Nd:YAG (1064 nm) laser irradiation to full-mouth scaling and root planing (FM-SRP) may offer additional benefit in the systemic inflammatory status of the patient, as depicted in a variety of systemic biomarkers over FM-SRP alone, up to 12 months after treatment. MATERIALS AND METHODS A total of 60 otherwise healthy stage III/IV periodontal patients were equally distributed in 3 groups. The control group received FM-SRP. In laser A group, 1 week after FM-SRP, Nd:YAG laser irradiation was delivered in periodontal pockets with PD ≥ 4 mm using specific settings (3 W, 150 mJ, 20 Hz, 100 μs). In laser B group Nd:YAG laser irradiation was delivered twice, 1 week after FM-SRP and 1 week later with different settings compared to laser A (2 W, 200 mJ, 10 Hz, 100 μs). RESULTS A significant reduction (p = 0.038) of IL-1β serum levels at the 6-month time point was observed for laser A group. IL-6 was found statistically significantly increased (p = 0.011) in the control group at the 6-week time point, whereas no difference was reported for the laser-treated groups (laser A, laser B). CONCLUSIONS The adjunctive use of Nd:YAG laser irradiation, prevented from IL-6 increase after FM-SRP, 6 weeks after treatment. Similarly, Nd:YAG laser irradiation (3 W, 150 mJ, 20 Hz,100 μs) was associated with significantly lower IL-1β levels, 6 months post-operatively. CLINICAL RELEVANCE Additional Nd:YAG laser application to FM-SRP may provide a potential beneficial effect on systemic inflammation. TRIAL REGISTRATION NUMBER ISRCTN26692900.

Abstract
AIM To investigate the effects of low-level laser therapy (LLLT) as an adjunct to non-surgical periodontal treatment (NSPT) on the plasminogen-activating system. MATERIALS AND METHODS Stage 3-4 Grade C periodontitis and age-gender-matched healthy individuals participated in the split-mouth study (ClinicalTrials.gov identifier, NCT05233501). The study groups were Periodontitis/NSPT (Sham); Periodontitis/NSPT + LLLT (LLLT); Healthy (Control). Following NSPT, LLLT was applied on Days 0, 2 and 7. Clinical parameters were recorded at baseline and on Day 30. Gingival crevicular fluid (GCF) was collected at baseline, on days 7, 14, and 30; tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) levels were measured with ELISA. RESULTS Clinical parameters, total GCF tPA (tPAt) and PAI-1 (PAI-1t) levels significantly reduced in LLLT and Sham groups (< 0.001). GCF tPAt levels in LLLT were significantly lower (< 0.05) than Sham on Day 7. GCF tPAt levels in periodontitis groups were significantly higher than the Control at baseline, on Days 7 and 14 (< 0.01). By Day 30, both groups decreased to control levels (> 0.05). GCF PAI-1t levels were significantly lower in LLLT than the Sham on day 30 (< 0.01), comparable to healthy controls (> 0.05). CONCLUSION Adjunctive LLLT modulates the plasminogen activating system in severe periodontitis by altering GCF tPA and PAI-1 levels. CLINICAL RELEVANCE LLLT as an adjunct to non-surgical periodontal treatment in patients with Stage 3-4 Grade C leads to reduced plasminogen activation.

Effect of Electrocautery and Laser Treatment on the Composition and Morphology of Surface-Modified Titanium Implants. Bioengineering (Basel) 2023; 10:1251. [PMID: 38002374 PMCID: PMC10669704 DOI: 10.3390/bioengineering10111251] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 10/20/2023] [Accepted: 10/24/2023] [Indexed: 11/26/2023] Open
Abstract
The purpose of this study was to investigate the effects of different peri-implantitis treatment methods (Er,Cr:YSGG laser, diode laser, and electrocautery) on various titanium implant surfaces: machined; sandblasted, large-grit, and acid-etched; and femtosecond laser-treated surfaces. Grade 4 titanium (Ti) disks, with a diameter of 10 mm and a thickness of 1 mm, were fabricated and treated using the aforementioned techniques. Subsequently, each treated group of disks underwent different peri-implantitis treatment methods: Er,Cr:YSGG laser (Biolase, Inc., Foothill Ranch, CA, USA), diode laser (Biolase, Inc., Foothill Ranch, CA, USA), and electrocautery (Ellman, Hicksville, NY, USA). Scanning electron microscopy, energy-dispersive X-ray spectroscopy, and wettability were used to characterize the chemical compositions and surfaces of the treated titanium surfaces. Significant changes in surface roughness were observed in both the electrocautery (Sa value of machined surface = 0.469, SLA surface = 1.569, femtosecond laser surface = 1.741, and p = 0.025) and Er,Cr:YSGG laser (Ra value of machined surface = 1.034, SLA surface = 1.380, femtosecond laser surface = 1.437, and p = 0.025) groups. On femtosecond laser-treated titanium implant surfaces, all three treatment methods significantly reduced the surface contact angle (control = 82.2°, diode laser = 74.3°, Er,Cr:YSGG laser = 73.8°, electrocautery = 76.2°, and p = 0.039). Overall, Er,Cr:YSGG laser and electrocautery treatments significantly altered the surface roughness of titanium implant surfaces. As a result of surface composition after different peri-implantitis treatment methods, relative to the diode laser and electrocautery, the Er,Cr:YSGG laser increased oxygen concentration. The most dramatic change was observed after Er:Cr;YSGG laser treatment, urging caution for clinical applications. Changes in surface composition and wettability were observed but were not statistically significant. Further research is needed to understand the biological implications of these peri-implantitis treatment methods.

Abstract
Objectives The current research was conducted to evaluate the use of a diode laser and a bone graft (hydroxyapatite [HA] + β-tricalcium phosphate [β-TCP]) in healing of intrabony defects. Materials and Methods In this split-mouth evaluation, 40 patients with bilateral intrabony defects were treated with, Group I (control) - bone graft alone (HA + β-TCP) and Group II, (test) - bone graft with a diode laser. The clinical and radiologic parameters of all patients, such as plaque index (PI), probing depth (PD), gingival index (GI), gingival recession (GR), and relative clinical attachment level (RCAL) were recorded at baseline, after 3 months and after 6 months. Results Reductions in PI, PD, GI, GR, and RCAL were found after 6 months. Furthermore, significant differences were displayed in the intra-group comparison while those of the inter-group evaluation (P > 0.05) were insignificant. Conclusion In both groups, considerable decrease in intrabony pockets was discovered; however, the inter-group comparison was insignificant in relation to GR and RCAL.

Clin Exp Dent Res 2023; 9:757-763. [PMID: 37649328 PMCID: PMC10582223 DOI: 10.1002/cre2.769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/12/2023] [Accepted: 07/15/2023] [Indexed: 09/01/2023] Open
Abstract
INTRODUCTION Scaling and root planning (SRP) is still the gold standard of nonsurgical periodontal therapy, and it has been accompanied by several supportive therapies in recent years. One of the most studied methods is the diode laser, thanks to its thermal and bactericidal properties. Our trial intended to verify whether it could influence the chemical bond between calculus and the root surface. OBJECTIVES The aim of the study was to assess the efficacy of the diode laser prior the mechanical removal of calculus in an in vitro application. The reduction in time and the number of strokes required to clean the untreated root surfaces were evaluated as primary outcomes. The pressure was considered as a secondary outcome. METHODS A total of 75 extracted human teeth with subgingival calculus were assigned equally among three treatment groups (n = 25) according to the size of the occupied areas, which were classified by evaluating the pixel numbers. The groups were assigned to either no pretreatment application (A), Laser Diode Fox III (Sweden & Martina) (B) or Wiser Laser Evolution (Doctor Smile) (C). The weight for instrumentation was calibrated for an After Five curette (Hu-Friedy, Chicago). A new set of tools was used for each group, and the curettes were sharpened after each use with the Sidekick sharpener (Hu-Friedy, Chicago). RESULTS A Kruskal-Wallis test was used to assess the significance for each considered parameter. The results were statistically significant for each parameter for the two groups where the laser was used compared to the control group. CONCLUSIONS Despite the limitations of an in vitro study, data showed that the diode laser had an overall positive effect on root debridement, facilitating SRP in terms of stroke count, time, and pressure.

Abstract
Several types of phototherapy target human pathogens and Porphyromonas gingivitis (Pg) in particular. The various approaches can be organized into five different treatment modes sorted by different power densities, interaction times, effective wavelengths and mechanisms of action. Mode 1: antimicrobial ultraviolet (aUV); mode 2: antimicrobial blue light (aBL); mode 3: antimicrobial selective photothermolysis (aSP); mode 4: antimicrobial vaporization; mode 5: antimicrobial photodynamic therapy (aPDT). This report reviews the literature to identify for each mode (a) the putative molecular mechanism of action; (b) the effective wavelength range and penetration depth; (c) selectivity; (d) in vitro outcomes; and (e) clinical trial/study outcomes as these elements apply to Porphyromonas gingivalis (Pg). The characteristics of each mode influence how each is translated into the clinic.

Abstract
OBJECTIVES The aim of this study was to evaluate the clinical outcomes of diode laser as an adjunct to nonsurgical periodontal therapy (NSPT) for residual periodontal pockets in mandibular second molars. MATERIALS AND METHODS Sixty-seven mandibular second molars (154 residual periodontal pockets) were recruited into the study and randomly assigned to the Laser + NSPT group and the NSPT group. The Laser + NSPT group underwent NSPT adjunct with diode laser radiation (wavelength: 810 nm, power: 1.5 W, 40 s maximum), while the NSPT group underwent nonsurgical periodontal therapy alone. Clinical parameters were measured at baseline (T0) and 4(T1), 12(T2), and 24(T3), weeks after treatment. RESULTS Periodontal pocket depth (PPD), clinical attachment loss (CAL), and bleeding on probing (BOP) in both groups showed significant improvements at the end of study compared to baseline. The reductions of PPD, CAL, and BOP in the Laser + NSPT group were significantly greater than NSPT group. At T3, the Laser + NSPT group had a mean PPD of 3.06 ± 0.86 mm, CAL of 2.58 ± 0.94 mm and BOP of 15.49%, while the NSPT group had a mean PPD of 4.46 ± 1.57 mm, CAL of 3.03 ± 1.25 mm and BOP of 64.29%. CONCLUSIONS The diode laser as an adjunct to nonsurgical periodontal therapy may contribute to clinical outcomes for residual periodontal pockets. However, the approach may cause reduction of keratinized tissue width. TRIAL REGISTRATION NUMBER This study was registered in the Chinese Clinical Trial Registry ChiCTR2200061194. CLINICAL RELEVANCE Diode laser as an adjunct to nonsurgical periodontal therapy may contribute to the clinical outcomes for residual periodontal pockets in mandibular second molars.

Abstract
Introduction As is known, periodontal pathogens and their products as well as inflammatory mediators produced in periodontal tissues might enter the bloodstream, causing systemic effects and/or contributing to systemic diseases. Aim To evaluate the effect of diode lasers on the incidence of bacteremia associated with ultrasonic scaling and its clinical efficacy as an adjunct to scaling in the treatment of moderate periodontitis. Result The use of diode laser is more effective in killing or detoxifying periodontopathic bacteria such as P. gingivalis associated with chronic periodontitis as compared to ultrasonic alone with ablate bacteria only when it comes in contact with plaque biofilm directly. Conclusion The results of study confirm the previously reported findings that bacteremia is caused by ultrasonic scaling and adjunct use of diode laser with scaling has the potential to reduce the bacteremia associated with ultrasonic scaling alone.

Abstract
Objective The current study looked at how well bone graft (hydroxyapatite + platelet-rich plasma (PRP)) and a diode laser treated infrabony defects. Materials and Method Twenty patients with bilateral infrabony deficiency were treated in a split-moth evaluation with bone graft (hydroxyapatite + PRP) alone (group I) (control) and bone graft combined with a diode laser (group II) (test). Clinical and radiologic measures such as the relative clinical attachment level (RCAL), probing depth (PD), gingival index (GI), and plaque index (PI) were recorded at baseline, 3 months later, and 6 months later in all patients. Result At the 6-month follow-up, there was a decline in the plaque index, probing depth, gingival index, and relative clinical attachment level. Conclusion When compared across groups, the intrabony pocket was significantly reduced with either the bone graft (hydroxyapatite + PRP) or in conjunction with the laser.

Abstract
Background Recently, various adjunctive treatment options along with Scaling and root planing (SRP) such as local drug delivery, medications, and lasers have been introduced for the treatment Chronic periodontitis (CP) but literature is limited. Aim To evaluate the clinical efficacy of 940 nm diode laser and propolis gel in adjunct to Scaling and root planing (SRP) in the treatment of CP. Subjects and Methods Randomized clinical trial was conducted among 30 CP patients with a probing depth of ≥5 mm was allocated randomly into Group 1 (SRP), Group 2 (SRP + diode laser), and Group 3 (SRP + propolis gel). Plaque index, gingival index, pocket probing depth, and clinical attachment level were assessed at baseline, one and three months. Data analysis was performed using SPSS version 17 for windows, and statistical techniques employed were repeated measures by using One-way ANOVA, Tukey's HSD, independent t-test, and paired t-test. Results Post-treatment sites among all the three groups showed statistically significant reduction in Periodontal index (PI), Probing pocket depth (PPD), and Clinical attachment level (CAL), whereas gingival inflammation was significantly reduced in groups 2 and 3 from baseline to one and three months. On comparison, at baseline, all clinical parameters were statistically insignificant. At one month, the mean difference of PI, Gingival index (GI) was statistically significant between group 1 and 2 whereas the mean difference of CAL and PPD were statistically significant from group 1 to groups 2 and 3. Conclusions Lasers with SRP were greatly effective in reducing gingival inflammation, PPD, and CAL. Propolis gel also offered encouraging and promising clinical results but still needs further long-term studies to establish its precise role in the treatment of CP.

Abstract
The present study aimed to confirm the usefulness of a multi-laser handpiece system currently under development. Implants were placed in the tibia of rabbits using a conventional separate laser-implant handpiece system (control group; SurgicPro+; NSK, Kanuma, Japan and Epic 10; Biolase, Irvine, CA, USA) and a multi-laser handpiece system (experimental group; BLP 10; Saeshin, Daegu, Korea). Implants were placed in left and right tibias of five rabbits using a conventional laser-implant handpiece system and a multi-laser handpiece system (N = 5 per group). Subsequently, micro-computed tomography (micro-CT; bone-to-implant contact evaluation), implant stability quotient (ISQ) measurement, and histological evaluations were performed to confirm the implant placement results. The independent t-test and the paired t-test were used to compare the ISQ values and the results of the two implant-laser handpiece groups (α = 0.05), respectively. No statistically significant difference in micro-CT, ISQ, and histological evaluations was observed between implant placement by the two systems (p > 0.05) except implant initial stability. The use of the multi-laser handpiece system is expected to produce the same results as a conventional separate laser-implant handpiece system with the higher implant initial stability. Additionally, it will potentially make the clinical environment more pleasant and will provide convenience for the clinicians.

Abstract
Increasing the disinfection during non-surgical treatment of periodontitis is primordial. This study assesses the effectiveness of sodium hypochlorite and a 980 nm diode laser in non-surgical treatment of periodontitis. Thirty sites of localized periodontitis with a probing pocket depth (PPD) of ≥ 6 mm were included. Fifteen underwent scaling root planing (SRP group) and 15 underwent SRP + 0.5% NaOCl and a 980 nm diode laser (study group). A biological molecular test and real time polymerase chain reaction (RT-PCR) were performed before (T0) and after intervention (T1). Total bacterial count and counts of Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Prevotella intermedia, Peptostreptococcus micros, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans, Eubacterium nodatum, Capnocytophaga gingivalis were assessed. Plaque index (PI), bleeding on probing (BOP), gingival recession (GR), PPD and clinical attachment loss (CAL) were evaluated at T0, and 3 and 6 months after. Study group showed a statistically significant reduction of TBC (5.66 × 108 CFU/mL) compared to SRP (6.2 × 109 CFU/mL). Both groups showed a statistically significant reduction of Treponema denticola, Tannerella forsythia, Prevotella intermedia, Peptostrep. (micromonas) micros and Fusobacterium nucleatum; however, a significant reduction of Eubacterium nodatum and Capnocytophaga gingivalis was observed in the study group. At T6, both groups had a statistically significant reduction of PI, BOP, GR, PD and CAL. The study group showed more GR compared to SRP and a significant reduction of PD (4.03 mm ± 0.49) compared to SRP (5.28 mm ± 0.67). This study reveals that NaOCl and a diode laser are effective as an adjunctive to the non-surgical treatment of periodontitis.

Dent J (Basel) 2022; 10:dj10070119. [PMID: 35877393 PMCID: PMC9317475 DOI: 10.3390/dj10070119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 06/17/2022] [Accepted: 06/27/2022] [Indexed: 12/04/2022] Open
Abstract
The aim of this cross-sectional study was to evaluate the status of laser use and training in the U.S. and Canadian graduate periodontology programs. A survey questionnaire was sent electronically to 55 periodontology program directors in North America. The questions focused on laser implementation, types of lasers used, for which procedures lasers were used, and level of education/clinical training provided to residents. Data were analyzed using descriptive statistics and Fisher’s exact test. Twenty-two directors responded (40%). Most programs (86%) used lasers and 89% used a diode laser. Laser treatment was the most used for periimplantitis (84%). Fifteen programs (79%) provided didactic and clinical training, with 47% programs giving 4–12 h of didactic training. In 53% of programs, residents completed 4 to10 procedures. Only 29% of programs had residents who had received a certification in lasers, with most (80%) programs requiring between 1–9 cases for certification. Of the participants not providing laser training, the major barrier was indicated as being “expense”, with 68.7% reporting plans to implement laser education. Conclusions: Most graduate periodontics programs were providing laser training and treatment. There was great variability regarding the training methods, specifically in number of dedicated laser courses, time allocated for laser training, and prerequisites for laser certification.

Abstract
Background This study aimed to assess the effect of diode laser combined with minocycline hydrochloride in conventional nonsurgical periodontal therapy. Methods Ninety-two patients and 1206 teeth were included in this study. The patients were diagnosed moderate or severe periodontal diseases with the presence of teeth in at least 3 quadrants in the oral cavity. Each patient’s quadrants were randomly divided into three treatment groups as following, Control group: scaling and root planning (SRP); Experimental group 1 (Exp 1): SRP + minocycline hydrochloride; Experimental group 2 (Exp 2): SRP + 809 nm diode laser + minocycline hydrochloride. The minocycline in Exp 1 and Exp 2 was applied once per week, for 4 weeks. Clinical examinations including periodontal probing depth (PD), clinical attachment level (CAL) and bleeding index (BI), and the secretion of inflammatory factor (tumor necrosis factor, TNF-α) was detected by ELISA before and 3, 6 months after the treatments. The differences among these groups were assessed by One-Way ANOVA and Kruskal–Wallis test. P-value < 0.05 was considered significant. Results All the periodontal indexes (PD, CAL and BI) were improved after each treatment and the secretion of TNF-α was reduced for all three groups. In patients with deep periodontal pockets, Exp 2 showed significant improvements in all indexes comparison with Con group and Exp group 1. Conclusions The synergistic effect of SRP and 809 nm diode laser combined with minocycline hydrochloride could play an efficient and reliable effect in the nonsurgical periodontal treatment approach. Trial registration The clinical trial was retrospectively registered in chictr.org.cn with registration ChiCTR2100051708 (01/10/2021).

Disinfection Potential of 980 nm Diode Laser and Hydrogen Peroxide (3%) in "Critical Probing Depths" Periodontal Pockets: Retrospective Study. Life (Basel) 2022; 12:life12030370. [PMID: 35330121 PMCID: PMC8953835 DOI: 10.3390/life12030370] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 02/25/2022] [Accepted: 02/28/2022] [Indexed: 12/23/2022] Open
Abstract
A successful treatment of periodontitis depends largely on the successful elimination of the periodontopathogens during non-surgical and surgical mechanical debridement. In this retrospective study, data collection was conducted from 2017 to 2021. The retrospective study included 128 patients with 128 sites of localized periodontitis with pocket depths > 5 mm. The included data were based on sites that received conventional mechanical debridement followed by different adjunctive approaches. In total, 30 patients did not receive any additional treatment (SRP group), 30 patients received SRP + 980 nm diode laser irradiation only (SRP + laser), 30 patients received SRP + 3% hydrogen peroxide irrigation (SRP + H2O2) only and 30 patients received a combined treatment of 3% hydrogen peroxide and 980 nm diode laser irradiation (SRP + H2O2 + laser). Total bacterial counts (TBC) in the periodontal pocket collected for all participants before treatment, immediately after treatment, 6 weeks after treatment, 12 weeks after treatment and 6 months after treatment were statistically analyzed and compared. When the laser was used, irradiation parameters were 10 μsec/pulse duration, 10 kHz, pick power of 10 W, average power of 1 W, irradiation time of one minute with inward and outward movements, and fiber diameter of 320 μm. The irradiation was repeated 3 times/pocket. When hydrogen peroxide was used, the irrigation was conducted for one minute and repeated 3 times. The maximum reduction in TBC was obtained when SRP was coupled with 3% H2O2 irrigation followed by 980 nm diode laser irradiation. After six months of follow-up, a significant reduction in TBC was obtained for the group of SRP + H2O2 + laser when compared to all the other groups, from 7.27 × 107 before intervention to 3.21 × 107 after six months. All three approaches to SRP showed a significant reduction in TBC immediately after treatment. Values were 3.52 × 107, 4.01 × 106, 9.58 × 106, 1.98 × 106 for SRP alone, SRP + diode, SRP + H2O2 and SRP + H2O2 + diode laser, respectively. At 6 months, we saw no significant difference between SRP + laser and SRP + H2O2 with 4.01 × 107 and 4.32 × 107, respectively. This retrospective study reveals that after SRP, irrigation with 3% hydrogen peroxide and irradiation with a 980 nm diode laser within specific treatment protocol can be used as an additional approach to conventional SRP to increase the disinfection of the periodontal pockets > 5 mm.

Abstract
Context: Tumor necrosis factor-alpha (TNF-α) has been shown to play a critical role in the pathogenesis of periodontitis and diabetes. Nonsurgical periodontal therapy was shown to reduce inflammation and improves glycemic status. Recently, adjunctive low level laser therapy (LLLT) has been shown to alter the inflammatory process. Aim: To evaluate and compare the alteration in TNF-α levels before and after treatment in patients with periodontitis with and without type 2 diabetes mellitus (T2DM). Settings and Design: Randomised clinico-biochemical study was carried out for 8 weeks from September 2019 to December 2020. Materials and Methods: Sixty-four participants were divided into Groups A (periodontitis) and B (periodontitis associated with T2DM), based on probing depth ≥5 mm, clinical attachment level ≥2 mm, and history of T2DM. Later were subdivided into A1, A2, B1, B2, based on assigned treatments. Clinical periodontal parameters and salivary TNF-α levels were evaluated and compared at baseline to 8 weeks. Statistical Analysis: Multiple group comparisons were done using analysis of variance, intra group comparisons were made using t-tests. Results: Comparison of periodontal parameters and salivary TNF-α levels from baseline to 8 weeks showed statistically significant difference (P < 0.05) in all groups, indicating a positive effect of scaling and root planing (SRP) and adjunctive LLLT. Conclusion: Both SRP and SRP with adjunctive LLLT effectively altered TNF-α levels, correlating reduced periodontal inflammation.

Abstract
Aims: Sclerostin is an inhibitor of bone formation, and laser irradiation enhances osteoblast proliferation. The objective of this study was to assess and compare the gingival crevicular fluid (GCF) sclerostin level and clinical parameters of chronic periodontitis patients following the application of diode laser (810 nm) as an adjunct to scaling and root planing (SRP). Subjects and Methods: Fifteen systemically healthy chronic periodontitis patients (age 35–55 years) with probing pocket depth ≥5mm were included in this split-mouth study. SRP and pocket irradiation with diode laser were done in the test group and SRP alone in the control group at baseline. Low-level laser therapy application and saline irrigation were done in both the groups, respectively, in the 2nd and 3rd visits. Two microliters of GCF samples was collected from both the groups at baseline before treatment and on the 90th day for the assessment of sclerostin concentration. Results: This study showed a statistically significant reduction of clinical parameters in the test and control groups at the end of 3 months. Both the groups showed a statistically significant reduction of sclerostin levels in GCF after 3 months, in which the test group (125.80 ± 28.21 to 82.80 ± 9.31) showed a highly significant reduction (P = 0.000). Conclusions: The adjunctive use of laser had shown a beneficial effect in terms of clinical parameters and osteoblast proliferation by the reduction in the levels of sclerostin in GCF. From the observations of this study, it can be concluded that the therapeutic effectiveness of diode laser as an adjunct to SRP is having a beneficial effect and sclerostin can be used as a potent biomarker.

Abstract
Introduction: This study evaluated the effectiveness of an 810-nm diode laser as an adjunct to scaling and root planning (SRP) in improving periodontal parameters in patients with chronic periodontitis. Methods: This randomized clinical trial consisted of 36 patients (16 females and 20 males) with chronic periodontitis and pocket depths of 4-6 mm. The quadrants were randomly divided into two sides; one side of each patient was selected as the laser group (SRP + laser) and the other side served as the control group (SRP alone). An 810-nm diode laser was applied in the laser side to remove the outer gingival epithelium (1.5 W, CW) as well as the inner epithelium of the periodontal pockets (1 W, CW). The clinical parameters including bleeding on probing (BOP), probing depth (PD), plaque index (PI), and clinical attachment level (CAL) were measured at baseline and 6 and 18 weeks after therapy. Results: In both groups, there was a significant improvement in BOP, PD, PI and CAL over the course of the experiment (P < 0.001). Significantly lower BOP was found in the SRP + laser group than the SRP alone group after 6 and 18 weeks of intervention (P < 0.05). The difference in other parameters was not significant between the two groups, neither at 6 nor at 18 weeks after the treatment (P > 0.05). Conclusion: Within the limitations of this study, the association of the diode laser with standard non-surgical periodontal therapy (SRP) provided minimal additional benefits for patients with moderate chronic periodontitis.

Abstract
BACKGROUND Periodontitis is a chronic inflammatory disease that is mainly initiated by plaque biofilm which may require treatment using periodontal flap surgery. Recently, diode lasers have become popular in the field of periodontology owing to advantages such as antibacterial effect, promoting angiogenesis, and providing hemostasis. However, scientific data on application of diode laser in periodontal flap surgery and its benefits are limited. Hence, the aim of the study was to investigate the adjunctive effect of removal of remnant pocket epithelium by 980 nm diode laser and biostimulation in modified Widman flap (MWF) surgery for the treatment of chronic periodontitis. MATERIALS AND METHODS A total of 20 patients with generalized chronic periodontitis with pocket probing depth (PPD) ≥5mm post Phase I therapy were selected for this split-mouth study. MWF surgery was performed in Group 1, and in Group 2, MWF surgery with adjunctive diode laser de-epithelization and biostimulation was done. Clinical parameters including PPD, clinical attachment level, plaque index, and gingival index were recorded at baseline and 3 months following treatment, and postprocedural pain (Visual Analog Scale [VAS] score) was assessed 1-week posttreatment. In addition, colony-forming units/milliliter (CFU/ml) of anaerobic bacteria at baseline and 3 months were microbiologically examined. RESULTS MWF surgery along with diode laser led to a significant improvement in Group 2 compared to Group 1 in clinical parameters such as PPD, relative clinical attachment level, VAS score as well as microbial parameter CFU/ml after 3 months. CONCLUSION Diode laser as an adjunct to MWF in chronic periodontitis can provide enhanced clinical attachment gain with little postoperative discomfort.

Abstract
BACKGROUND Studies have reported a positive effect on bone healing and the elimination of microorganisms placed on the titanium implants, while others have not confirmed the positive photobiomodulation therapy (PBMT) effects on bone regeneration and bone structure around the implants. PURPOSE The aim of the present study was to address the following questions: Does PBMT improve implant stability and affect microbiota around dental implants in the early stage of osseointegration? MATERIALS AND METHODS This study was designed as randomized-controlled prospective, split mouth, single-blinded clinical trial. Implants were randomly divided into two groups and implants placed in the test group were treated with Gallium-aluminum-arsenide (GaAlAs) diode laser with PBMT immediately after surgery and for 15 days (n = 47). In the control group, implants were not irradiated(n = 46). The primary stability of the implants was measured by the Resonance frequency analysis (RFA) after insertion and the secondary stability values were recorded at 30th, 60th, and 90th days after surgery as implant stability quotient (ISQ). The hand-held RFA was held perpendicular to the jaw line as indicated by the manufacturer for buccal-lingual (BL), mesial-distal (MD), and lingual-buccal (LB) measurement and different measurements were analyzed as separately. RESULTS Significantly higher magnetic RFA values were achieved on the 90th day in all measurement sides for both groups. ISQ levels in groups at baseline and the day-30, 60, and 90. ISQ readings were not statistically significant between test and control groups for each time point. A statistically significant increase in ISQ reading for BL, MD, and LB dimensions in both groups was noted from baseline to the day-90 (P < .05). CONCLUSION It was concluded that PBMT did not have a clinically significant effect on implant stabilization, especially in terms of ISQ values at early alveolar bone healing term. Clinical trial number is NCT04495335.

Abstract
AIM To compare the adjunctive effects of lasers or antimicrobial photodynamic therapy (aPDT) to non-surgical mechanical instrumentation alone in untreated periodontitis patients. MATERIALS AND METHODS Two focused questions were addressed using the Population, Intervention, Comparison and Outcome criteria as follows: in patients with untreated periodontitis, (a) does laser application provide adjunctive effects on probing pocket depth (PPD) changes compared with non-surgical instrumentation alone? and (b) does application of aPDT provide adjunctive effects on PPD changes compared with non-surgical instrumentation alone? Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Results of the meta-analysis are expressed as weighted mean differences (WMD) and reported according to the PRISMA guidelines. RESULTS Out of 1,202 records, 10 articles for adjunctive laser and 8 for adjunctive aPDT were included. With respect to PPD changes, 1 meta-analysis including 2 articles (total n = 42; split-mouth design) failed to identify a statistically significant difference (WMD = 0.35 mm; 95%CI: -0.04/0.73; p = .08) in favour of adjunctive aPDT (wavelength range 650-700 nm). In terms of adjunctive laser application, a high variability of clinical outcomes at 6 months was noted. Two articles included patient-reported outcomes and 10 reported on the presence/absence of harms/adverse effects. CONCLUSIONS Available evidence on adjunctive therapy with lasers and aPDT is limited by (a) the low number of controlled studies and (b) the heterogeneity of study designs. Patient-reported benefits remain to be demonstrated.

Abstract
Objective: Although multiple applications of antimicrobial photodynamic therapy (aPDT) and antibiotics (AB) have been proved to have a biomodulatory effect, no systematic review has exclusively compared the effectiveness as an adjunct to scaling and root planning (SRP). This study sought to systematically compare the clinical efficacy of repeated antimicrobial photodynamic therapy (RaPDT) with that of the systemic administered AB as an alternative approach to SRP in treating periodontitis. Methods: In this systematic review, two independent reviewers searched PubMed, Embase, and CENTRAL databases. The primary outcomes assessed were bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). Results: Five randomized clinical trials were included after screening 457 records. Results revealed that when patients from all studies were categorized based on their baseline CAL, AB demonstrated significant benefits over RaPDT in the improvement of PPD [weighted mean differences (WMD) = -0.36, 95% confidence interval (CI) = -0.71 to -0.02, p < 0.05] in the patients with severe periodontitis (CAL baseline ≥5 mm) 3-month postoperatively, and CAL (WMD = -0.57, 95% CI = -1.11 to -0.04, p < 0.05) at 6-month observation. Nevertheless, AB failed to show significant benefits over RaPDT, when CAL baseline <5 mm in terms of clinical parameters. Conclusions: RaPDT may represent an alternative approach to SRP in treating slight-to-moderate periodontitis cases (CAL <5 mm), whereas AB remain a main therapy for treating severe periodontitis (CAL ≥5 mm).

Abstract
OBJECTIVE To evaluate and compare the effects of laser monotherapy with non-surgical mechanical instrumentation alone in untreated periodontitis patients. MATERIALS AND METHODS A focused question was formulated based on the Population, Intervention, Comparison, Outcome, and Study design criteria (PICOS): in patients with untreated periodontitis, does laser mono-therapy provide adjunctive effects on pocket probing depth (PPD) changes compared with non-surgical instrumentation alone? Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. The results of the meta-analyses are expressed as weighted mean differences (WMD) and reported according to the PRISMA guidelines. RESULTS The search yielded 1268 records, out of which 8 articles could be included. With respect to PPD changes, a meta-analysis including 5 articles (n = 148) failed to identify statistically significant differences in favor of laser monotherapy for PPD change (WMD = 0.14 mm; 95% CI: - 0.04/0.32; z = 1.51; p = 0.132) nor for clinical attachment level (CAL) (WMD = 0.04 mm; 95% CI: - 0.35/0.42; z = 0.19; p = 0.850). Data on cost-effectiveness are lacking. One study reported patient-related outcome measures (PROMS). CONCLUSIONS In untreated periodontitis patients, laser monotherapy does not yield superior clinical benefits compared with non-surgical mechanical instrumentation alone. CLINICAL RELEVANCE In untreated periodontitis patients, mechanical instrumentation with hand and/or ultrasonic instruments remains the standard of care.

Abstract
Background: Enterococcus is a part of normal gastrointestinal flora in human body. Nevertheless, antibiotic-resistant Enterococcus (ARE) is considered a key factor in nosocomial infections which result in a considerable increase in the rate of patient death due to referring of numerous patients to health centers annually, or lead to extended disease convalescence. Objective: This study aimed to evaluate the bactericidal effect at 405nm diode at a laser power of 30 mW on ARE viability of clinical infections. Materials and Methods: In the present study, 30 isolates underwent antibiotic susceptibility test (AST) in which sensitivity to piperacillin (100 µg), rifampin (5 µg), and oxacillin (1 µg) were measured based on the Clinical and Laboratory Standards Institute (CLSI) guidelines. Afterwards, ten most resistant isolates were selected and irradiated by a 405 nm diode laser at a power of 30 mW for 180 and 240 seconds. The data were reported statistically as mean ± standard deviation, and the analysis of the data on varied bacteria was performed using ANOVA. The result was evaluated by SPSS software and P value ≤0.05 was interpreted to be significant. Results: Bacterial viability decreased unsteadily to 10 resistant isolates. Moreover, enhancing irradiation time caused a lower viability rate in such a way that the viability of isolate 9 having the lowest viability rate was reduced from 2.94% in 180 seconds to 0.58% in 240 seconds. The result was evaluated by SPSS software and P value was determined to be significant, and P≤0.05 was laser irradiation for either 180 s or 240 s. Conclusion: Following the study results, 405 nm diode laser could be applied as a tool for eliminating clinical ARE, and it was useful for preventing hospital-acquired infections.

Abstract
Assessment of the efficacy of a single 810 nm diode laser application as an adjunctive treatment modality during the first intervention of non-surgical periodontal therapy (NPT). 25 patients diagnosed with chronic periodontitis underwent a split-mouth randomised control trial. The periodontal pockets of the test quadrants were treated with an 810 nm diode laser as an adjunct to NPT (Picasso GaAlAs; AMD Lasers). The laser was set at 1.0 W continuous wave, 400 µm tip, 796 W/cm2 peak power density and a 32 J/cm2 energy density. Therapeutic outcomes were evaluated based on the clinical parameters, which included probing pocket depth, recession, clinical attachment level, full mouth plaque score, full mouth bleeding on probing and tooth mobility. The baseline bacterial collection was completed from the periodontal pockets and then re-evaluated at 6 weeks. Clinical parameters demonstrated no statistical difference, with the exception of a statistically significant (P < 0.05) reduction in bleeding on probing for the test side. The test side resulted in a statistical increase of Capnocytophagaspecies and Treponemadenticola. The single application of the diode laser did not significantly improve the bacterial nor the clinical parameters in patients with chronic periodontitis.

Abstract
Background The present study systematically reviewed randomized controlled trials (RCT) to investigate the effect of diode laser therapy in the management of peri-implant mucositis.
Material and Methods The electronic databases were searched until January 2020. Outcome measures were bleeding on probing (BOP), plaque index (PI) and probing depth (PD). The addressed PICO question was: Is the diode laser therapy effective reducing the signs of inflammation as an adjunctive element in the non-surgical treatment of peri-implant mucositis?.
Results Eight randomized clinical trials (RCTs) were included in the systematic review for qualitative synthesis and three in the meta-analysis for quantitative synthesis. All studies included in the quantitative synthesis have low risk of bias according to the Cochrane collaborations’ tool. Diode laser as coadyuvant therapy significantly reduced plaque index (SMD: -1.24; -0.47/-1.53) but not in bleeding on probing (SMD: -0.84; -0.31/-1.53) or probing pocket depth (SMD: -1.36; -0.28/-1.69). Non-statistically significant reductions in peri-implant bleeding on probing and in probing pocket depth were also observed in the test groups of most studies included in the meta-analysis.
Conclusions The results should be interpreted cautiously due to the great heterogeneity in the methodology of the studies included in the systematic review. However the meta-analysis suggests that the use of diode lasers, as an adjunct in conventional non-surgical treatment of peri-implant mucositis, is promising in reducing the clinical signs of peri-implant mucositis, especially reducing the perii-implant plaque index. Key words:Peri-implant diseases, peri-implant mucositis, laser therapy, diode laser.

Abstract
Background Management of caries using minimally invasive dentistry is prevalent in dentistry today. A newer technology is to disinfect/sterilize caries in depth of the dental tissue with diode laser. However, to have a bactericidal effect, increased energy density of light amplification by stimulated emission of radiation (LASER) may be required which in turn may lead to higher thermal load causing harmful effects on vital pulpal tissue. Aims The aim was to evaluate temperature rise and efficacy of cavity disinfection with diode laser. Materials and Methods Twenty permanent molar teeth with dentinal caries were randomly assigned into two groups on the basis of LASER irradiation: Group 1 - at 1 W, Group 2 - at 2 W. The elevation of subsurface temperature during irradiation was measured using thermocouples positioned in the center of a prepared cavity. Dentinal samples were collected before and after disinfection of the cavity. These samples were subjected to microbiological evaluation for Streptococcus mutans on Mutans-Sanguis agar and Lactobacilli on Rogosa agar. Statistical Analysis Log transformed "t"-test and paired "t"-test were used for the statistical analysis. Results Although the reduction in microbial count revealed insignificant difference at two different wattages, the rise in temperature with 1 W was less than that with 2 W. Conclusion Efficacy of 1 W and 2 W is similar, but 1 W causes less thermal changes, thus, 1 W is recommended over 2 W.

Abstract
The meta-analysis aimed to systematically evaluate all the available pieces of evidence concerning the clinical effectiveness of Er,Cr:YSGG lasers (erbium, chromium, yttrium scandium gallium garnet laser) in the non-surgical treatment of patients with chronic periodontitis, and provide guidance for clinicians about the application of Er,Cr:YSGG lasers during the process of non-surgical periodontal treatments. The meta-analysis was conducted with data extracted from 16 randomized controlled clinical trials (RCTs) that compare Er,Cr:YSGG lasers adjunct/substitute to scaling and root planing (SRP) with SRP alone for the treatment of chronic periodontitis published in English or Chinese from January 2000 to January 2020. The weighted mean differences (WMDs) and 95% confidence intervals (CIs) were counted for probing depth (PD) reduction, clinical attachment level (CAL) gain, and visual analogue scale (VAS) score. Heterogeneity of each study was evaluated with the Q test. The publication bias was measured using Begg's adjusted rank correlation test. Sixteen RCTs with 606 patients were included in the meta-analysis. There were statistically significant differences between Er,Cr:YSGG lasers adjunct/substitute to SRP and SRP alone in the PD reduction at 1-month follow-up (WMD = ‑ 0.35, 95% CI [- 0.63, ‑ 0.07], P = 0.013), 3-month follow-up (WMD = - 0.342, 95% CI [- 0.552, - 0.132], P = 0.001), CAL gain at 3-month follow-up (WMD = - 0.17, 95% CI [- 0.31, 0.03], P = 0.017), and VAS score (WMD = - 2.395, 95% CI [- 3.327, - 1.464], P = 0.000) immediately after treatment. There were no significant differences of PD reduction and CAL change at 6-month follow-up. The present meta-analysis indicated that Er,Cr:YSGG lasers provided additional effectiveness in PD reduction and CAL gain at short-term follow-ups and there was less pain compared with SRP alone.

Abstract
Adjunctive use of laser devices as high reactive-level laser/light therapy (HLLT) or photobiomodulation therapy (PBMT) for periodontal therapy is known to be more effective on suppressing pain than conventional therapy, however, there are no systematic reviews addressed its effectiveness. This systematic review and meta-analysis aim to investigate the following clinical question (CQ): does adjunctive use of lasers with conventional therapy suppress the pain associated with periodontal treatment? A systematic and extensive literature search was performed to summarize the currently available knowledge to answer the CQ using the PubMed, Cochrane Library, and Web of Science databases for randomized controlled trials (RCTs) conducted before June 2020. Bias risk was assessed using the Cochrane tool for the risk of bias evaluation. A meta-analysis was performed on quantitative evaluation of pain control based on patient-reported outcomes. After an independent screening of 165 initial records, ten RCTs were included. Six of them focused on surgical procedures and the others on non-surgical periodontal pocket therapy. The protocols of HLLT, PBMT, and combination with HLLT and PBMT were employed in five, four and one RCTs, respectively. Following the assessment of bias risk, it is revealed that all RCTs had methodological weaknesses regarding the blinding of key personnel, although other bias risk factors were not evident. Meta-analysis showed that HLLT using erbium lasers significantly reduced the patient-reported pain immediately after treatment (two RCTs, p < 0.0001), while PBMT using diode lasers significantly reduced pain 2-7 days after treatment (two RCTs, p < 0.0001 to p = 0.03). The presented systematic review and meta-analysis suggest that the alternative use of HLLT using erbium lasers to conventional instrumentation can significantly suppress postoperative pain and that intraoperative or postoperative PBMT using diode lasers combined with periodontal surgery can significantly reduce postoperative pain. However, the evidence is still insufficient and more well-designed RCTs are required.

Abstract
The purpose of this study was to evaluate the possible benefits (in terms of periodontal status improvement and periodontal bacteria count reduction) of using 980 nm diode laser in the treatment of periodontitis in patients after myocardial infarction. Thirty-six patients under 65 years of age (mean: 56.3 ± 7.9) with periodontitis, 6 weeks to 6 months after myocardial infarction, were recruited for the study. The control group (n = 18) received SRP (scaling, root planing and polishing) while the test group (n = 18) received SRP followed by laser therapy of the periodontal pockets with 980 nm diode laser, 1 W, continuous wave mode, 20 s per tooth side. Procedures were repeated twice at 5-7 day intervals. Microbiological and periodontal examination, including periodontal pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP) and plaque control record (PCR), were performed before treatment, 2 weeks and 3 months after treatment. The study was registered on ClinicalTrials.gov with Identifier: NCT04145557, 29.10.2019 "retrospectively registered". Additional use of laser resulted in a significant reduction in pockets with PPD ≥ 7 mm (p = 0.0151). The diode laser reduced total bacteria count (p = 0.0154) and delayed recolonisation during a 3-month observation period. A significant increase in the number of Capnocytophaga gingivalis was observed in the control group (p = 0.048). Additional use of the diode laser after SRP had no significant effect on BOP, CAL and PCR. Within the limitations of our study, we can conclude that 980 nm diode laser can be a useful tool in the treatment of periodontitis in patients after myocardial infarction.

Abstract
Background: Mechanical debridement is the gold standard in the periodontitis therapy. However, it is suggested that adjunctive use of lasers can result in a more effective treatment outcome. Objective: Evaluate the efficiency of diode laser-assisted nonsurgical therapy of periodontitis as adjunctive to scaling and root planing (SRP). Methods: One hundred sixty vertical bone defects [pocket depth (PD) at baseline ≥6 mm] had been randomly allocated to receive SRP alone (group C) or SRP coupled to a diode laser (980 nm) protocol (group C+L): SRP, irrigation with hydrogen peroxide solution (3%), de-epithelization of the internal and external gingiva followed by blood stabilization, and coagulation by laser beam were made. Beam parameters: 10 μsec/pulse duration, 10 kHz, pick power of 10 W, average power of 1 W, and fiber diameter of 400 μm. Plaque index (PI), bleeding on probing, gingival recession (GR), clinical attachment level (CAL), and PD were measured at baseline, at 6 weeks, 12 weeks, 18 weeks, 6 months, and 12 months. Microbiological data were collected randomly from 26 pockets from both groups at baseline, 6 weeks, 12 weeks, and 6 months after treatment. Results: At all periods of follow-up, there was a significant difference between both groups in all clinical parameters except in GR. In group C+L, 76% of pockets had PD ≤3 mm after 12 months of follow-up and an average of PD = 1.77 ± 0.46 mm, while 56% of pockets in group control (C) had an average of PD = 5.00 ± 0.83 mm after 12 months of follow-up. Total bacteria count in group C + L was significantly lower compared to group C only at 12 weeks and 6 months of follow-up. Furthermore, there was high significant decrease in the number of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, and Prevotella intermedia at all the follow-up periods. Conclusions: As adjunctive to SRP, diode laser-assisted nonsurgical therapy of periodontitis has significantly improved clinical parameters of PI and POB and has significantly reduced the clinical attachment loss (CAL) and PD compared to the control group after 1 year of follow-up. A significant reduction in periodontal pathogens has been observed in group C + L only at 12 weeks and 6 months of follow-up.

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.

Bioengineering (Basel) 2020; 7:bioengineering7030093.

Abstract
The aim of the study was to investigate the effects of neodymium: yttrium aluminium garnet (Nd:YAG) (1064 nm) and erbium: yttrium aluminium garnet (Er:YAG) (2940 nm) laser energy on titanium when delivered with conventional optics (focusing handpieces or plain ended optical fibres) or with a conical tip. Machined and micro-roughened implant discs were subjected to laser irradiation under a variety of energy settings either dry (without water) or wet (with water). Samples were scanned using a 3D non-contact laser profilometer and analysed for surface roughness, volume of peaks and the maximum diameter of the ablated area. Conical tip designs when used with both lasers showed no surface effect at any power setting on both machined and micro-roughened implant surfaces, regardless of the irrigation condition. When used with conventional delivery systems, laser effects on titanium were dose related, and were more profound with the Nd:YAG than with the Er:YAG laser. High laser pulse energies caused surface fusion which reduced the roughness of micro-roughened titanium surfaces. Likewise, repeated pulses and higher power densities also caused greater surface modifications. The presence of water reduced the influence of laser irradiation on titanium. It may be concluded that conical fibres can reduce unwanted surface modification, and this may be relevant to clinical protocols for debridement or disinfection of titanium dental implants.

Abstract
Background:
Periodontal therapy consists of eliminating the inflammation, treating periodontal pockets, motivating the patient for oral hygiene, and, if necessary, for surgical treatment. Recently, the application of a diode laser is widely being investigated for periodontal disease treatment.
Objective:
The analysis and evaluation of the clinical and biochemical impact of diode laser periodontal treatment, compared to either surgical or non-surgical, therapy, was the aim of this study.
Methods:
The study involved 80 patients older than 18 with at least 20 teeth. Evaluation of periodontal parameters was done conveniently on a single-rooted tooth (incisive, canine, premolar) on six surfaces, before the start of periodontal therapy, and after three, and six months. The laser used in the study was a diode laser with a wavelength of 980 nm. Digital X-rays were taken for bone level evaluation before and after the treatment. The presence of a bone destruction mediator (Matrix metalloproteinase-8 - MMP-8) was evaluated by the dipstick immunoassay test. Biochemical analysis and radiographic measurements were evaluated at the baseline and six months after the treatment. The statistical analysis included χ2-test and one-way ANOVA.
Results:
The results of this study showed that diode laser treatment was more effective in reducing periodontal clinical parameters, lowering MMP-8 levels and reducing the bone loss, compared to the group treated with scaling and root planning, or with a surgical approach.
Conclusion:
Diode laser may be considered as an effective alternative for periodontal treatment, with benefits in clinical and biochemical parameters.

Comparison between Antimicrobial Photodynamic Therapy and Low-level laser therapy on non-surgical periodontal treatment: A Clinical Study. Photodiagnosis Photodyn Ther 2020; 31:101756. [PMID: 32302705 DOI: 10.1016/j.pdpdt.2020.101756] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2019] [Revised: 02/11/2020] [Accepted: 03/20/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Alternative antibacterial therapeutic modalities, such as antimicrobial photodynamic therapy (aPDT) and low-level laser therapy (LLLT), have been proposed to improve the effectiveness of periodontal treatment. However, clinical studies evaluating the efficiency of these treatments have been inconclusive, partly due to contradictory results regarding their clinical and microbiological effects. The aim of this study was to evaluate the clinical effects of aPDT and LLLT after a one-stage full-mouth disinfection (OSFMD) protocol during periodontitis treatment. METHODS A split-mouth clinical trial was conducted in 20 patients presenting at least two contralateral teeth with a probing pocket depth (PD) ≥ 5 mm and bleeding on probing (BOP) on both sides of the mouth. All patients were submitted to an OSFMD protocol. The selected sites randomly received either (1) aPDT (methylene blue as a photosensitizer activated by red and infrared diode laser) or (2) LLLT (red and infrared diode laser). Clinical parameters were assessed at baseline and at 4 and 12 weeks post-treatment. RESULTS Both treatment protocols promoted significant reductions in PD, number of deep pockets and BOP and an increase in clinical attachment level (CAL) after 4 and 12 weeks, but there were no differences between the two groups. There was no change in the gingival level (GL) of either group for all periods of analysis. A decrease in the number of moderate pockets (4-5 mm) was found in the LLLT group (5.15 ± 4.20) when compared to the aPDT group (7.10 ± 5.24), but only after 4 weeks. CONCLUSIONS In conclusion, both the aPDT and LLLT therapies promoted improvements in periodontal clinical parameters after the OSFMD protocol; however, in general, there were no distinct differences between the two treatment modalities evaluated in this study.

Effect of diode laser application as an adjunct to nonsurgical periodontal therapy on the reduction of red complex microorganisms in type 2 diabetics with chronic periodontitis. Lasers Med Sci 2020; 35:1403-1410. [PMID: 32193820 DOI: 10.1007/s10103-020-02997-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Accepted: 03/09/2020] [Indexed: 10/24/2022]
Abstract
Bactericidal and detoxification effects of diode laser (DL) have been reported in periodontal treatment. The objective of this study was investigating the additional effect of DL with nonsurgical periodontal treatment on the red complex bacteria in type 2 diabetes mellitus (DM) patients with chronic periodontitis (CP). Sixty type 2 DM patients with chronic periodontitis (CP) were randomly assigned in two parallel groups to receive scaling root planning (SRP, n = 30) or SRP followed by DL periodontal pocket irradiation (SRP + DL, n = 30). Recording of clinical parameters and subgingival plaque sampling were performed at baseline, and post therapy (1 and 3 months after treatment). Amounts of Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia were evaluated with quantitative RT-PCR. Significant reductions for numbers of all three bacterial species were observed at 1 and 3 months compared with baseline for both treatments (p < 0.001), but no significant differences were found between two groups regarding bacterial reductions at these follow-up time points. No additional benefit of DL as an adjunct to nonsurgical periodontal therapy was recognized in the reduction of P. gingivalis, T. denticola, and T. forsythia for type 2 DM patients with CP. Further studies are required to clarify the effects of diode laser on the other periodontopathogens.
