The efficacy of diode laser and subgingival air polishing with erythritol in treatment of periodontitis (clinical and microbiological study).

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.

Efficacy of Rose Bengal-Mediated Antimicrobial Photodynamic Therapy as an Adjunct to Scaling and Root Planing on Clinical and Microbiological Parameters in the Management of Chronic Periodontitis: A Single-Blinded, Randomized Controlled Clinical Trial.

Aim: The study aims to assess the efficacy of rose bengal (RB)-mediated antimicrobial photodynamic therapy (a-PDT) as an adjunct to scaling and root planing in the management of chronic periodontitis patients in terms of clinical parameters like gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and microbiological parameters like total microbial count, total red complex organism count, Porphyromonas gingivalis count, Treponema denticola count, and Tannerella forsythia count. Materials and Methods: In this randomized controlled clinical trial, a total of 30 patients were recruited who met the inclusion criteria. The participants were randomly allocated into group A with scaling and root planning (SRP) alone and group B with SRP + a-PDT. The clinical and microbiological parameters were measured at baseline and at 3-month follow-up. Intergroup and intragroup comparisons were performed using independent t test and paired t test, respectively. Value of p < 0.05 was considered as statistically significant. Results: At 3-month follow-up, group B treated with SRP + a-PDT showed statistically significant reduction in GI (0.58 ± 0.20) and PPD (1.81 ± 0.32 mm), gain in CAL (0.73 ± 0.04 mm), and reduction in total microbial count [2.80 ± 0.08 × 104 colony forming unit (CFU)], total red complex count (0.29 ± 0.14 × 102 CFU), P. gingivalis count (0.43 ± 0.13 × 102 CFU), T. denticola count (0.61 ± 0.04 × 102 CFU), and T. forsythia count (0.59 ± 0.04 × 102 CFU) as compared with group A (p < 0.05). Conclusion: RB-mediated a-PDT as an adjunct to SRP was significantly more effective in improving GI, PPD, and CAL and in reducing microbial count as compared with SRP alone in the management of chronic periodontitis.

Comparative evaluation of thermal impact of 980nm diode laser on soft tissue using irrigation and non-irrigation systems: A histomorphometric study.

Background: Diode laser is one of the most captivating technologies in dental practice. In periodontics, when used at appropriate settings, it possesses the best properties for selective surgical and nonsurgical procedures such as subgingival calculus removal without a thermal change of the root surface, and also provides tissue surface sterilization. However, lasers always produce a certain amount of thermal damage to the soft tissues. Therefore, this study aimed to comparatively evaluate the thermal impact of 980-nm diode laser incisions, when used with irrigation versus nonirrigation systems. Materials and Methods: The study was conducted on 24 gingival tissue samples obtained from the goat's mandible and maxilla. The samples were divided into two groups of 12 samples each, and laser incisions were given in 4 power settings, using 980-nm diode laser in super short pulse mode, with and without saline irrigation. Martius Scarlet Blue staining technique was used to prepare the histological slides. Then, slides were examined under a research microscope (Olympus CX 21), and the pictures of the slides were taken by mounting the camera onto the microscope mobile mount. The microscopic images hence obtained were analyzed for the depth and width of the incisions, area of carbonization, necrosis, and reversible damage, using the Digimizer image analysis software. Results: The results of this study demonstrated that the mean incision depth was higher (592.49 ± 180.97, P < 0.05), with less carbonization (25.52 ± 29.21, P = 0.00) and less necrosis (311.63 ± 156.441, P < 0.05) in the laser incisions with irrigation, as compared to the laser incisions given without irrigation system. Conclusion: Within the limitations of this study, it can be concluded that using an irrigation system causes less collateral damage while maintaining the incising efficiency of the diode laser. Further studies with a higher sample size, controlled irrigation systems, and incision techniques are needed to evaluate the efficiency of diode lasers for the clinical explanation of the results.

Surgical Correction of Ankyloglossia Using Diode Laser-Assisted Frenectomy in a Pediatric Patient: A Case Report.

Tongue-tie is a continuation of the lingual frenum that is attached to the tip of the tongue. It is a congenital oral anomaly that could restrict tongue movements, caused by a lingual frenum a membrane that originates from the floor of the mouth to the bottom of the tongue that is too thick and short, which limits the natural ability of the tongue to move and function. The tongue is an auxiliary organ that facilitates speaking, mastication, and deglutition. This condition may result in several difficulties including chewing, breastfeeding, speech, and pronunciation of particular words, as well as possessing social and mechanical consequences. Ankyloglossia can be seen in young age groups. The use of lasers has increased in dentistry in recent years. However, in oral and maxillofacial surgery, the use of lasers has been largely restricted to soft tissues, and less focus is placed on the use of hard tissues. Carbon dioxide (CO2) lasers, erbium-doped yttrium aluminum garnet (Er: YAG) lasers, and Er, the erbium, chromium: yttrium: scandium gallium-garnet (Cr: YSGG) lasers are among the several types of lasers that have been utilized in dentistry for correction of soft tissues as well as for hard tissues.

Laser Therapy Versus Traditional Scaling and Root Planing: A Comparative Review.

Scaling and root planing (SRP) removes bacterial plaque, calculus, and associated microorganisms from the surface of the tooth and the surrounding soft tissue. While complete eradication of pathogenic microbes is impossible, gross removal can lower the microbial load, which in turn reduces inflammation and contributes to positive clinical outcomes. Instrumentation in limited-access anatomic areas like furcation, grooves, deep pockets, concavities, and distal molar areas is technically demanding with traditional mechanical debridement. However, emerging advanced systems such as lasers with bactericidal and detoxification effects offer the benefit of reaching limited-access areas that traditional SRP cannot reach. A digitized search was done on PubMed, Embase, Medline, and Google Scholar using the keywords "lasers", "periodontal therapy", "scaling", and "root planing". Upon screening and reviewing, the shortlisted articles comprised narrative reviews, systematic reviews, randomized controlled trials, comparative studies, split-mouth studies, case series, and reports of non-surgical laser therapy and lasers as an adjunct to SRP. This review presents a comprehensive comparative evaluation of different laser modalities utilized in non-surgical periodontal treatment in contrast to standard SRP, rather than an exhaustive article review. It delves into the history and development of lasers, highlighting key advancements made in the realm of periodontics and dental care. This review includes an elucidation of the theory behind laser operation, along with an exploration of its intrinsic characteristics and breakdown of the various types of lasers that are currently available, and an examination of existing literature in both present and historical contexts regarding the comparison of various types of lasers with traditional periodontal treatment.

Clinical efficacy and pain control of diode laser-assisted flap surgery in the treatment of chronic periodontitis:A systematic review and meta-analysis.

Objective: To assess the diode laser-assisted periodontal flap surgery's clinical effectiveness and postoperative pain management in treating chronic periodontitis, and to offer evidence-based medical justification for the procedure's clinical use. Data sources and study selection: In this study, a computer combined with manual search was used to search for articles on diode laser-assisted periodontal flap surgery for the treatment of chronic periodontitis published from the establishment of the database to September 2023. The databases searched included China Academic Journal Full Text Database (CNKI), China Biomedical Literature Database (CBM), Chinese Science and Technology Journal Database (VIP), Wanfang Database, PubMed, Web of science, Cochrane Library, Embase, and Scopus. Two researchers independently performed the screening and study selection, following the inclusion and exclusion standards to extract basic information and required data. Meta-analysis of the included literature was performed using Revman V5.4 software. Result: Thirteen articles were analyzed. Meta-analysis showed that the use of the diode laser was effective in reducing patients' probing pocket depth (PPD) at 3 and 6 months postoperatively (3 months: MD = -0.46, 95 % CI = [-0.89, -0.03], P = 0.04; 6 months: MD = -0.35, 95 % CI = [-0.63, -0.06], P = 0.02), was able to effectively improve 3 month clinical attachment level (CAL) (MD = -0.36, 95 % CI = [-0.66, -0.06], P = 0.02), and was able to promote wound healing and reduce patients' early postoperative pain (MD = 0.67, 95 % CI = [0.01, 1.32], P = 0.05; MD = -1.67, 95 % CI = [-2.23, -1.00], and P < 0. 001), while for gingival index (GI), the use of diode laser did not have a significant effect. Conclusions: The available evidence suggests that the use of a diode laser adjunct is effective in reducing PPD, improving CAL, promoting wound healing, and reducing early postoperative pain in patients compared with flap application alone; however, for GI, diode lasers did not show any improvements. Clinical significance: Periodontal flap surgery fails to eliminate microorganisms from the soft tissue wall, potentially leading to recolonization, reinfection, and accompanying side effects such as pain and swelling. The use of a diode laser reduces PPD, improves CAL, and relieves early postoperative pain.

Using Laser Therapy and Topical Ozone as an Effective Intervention to Revolutionize Denture Stomatitis Treatment: A Case Report.

In dentistry, denture stomatitis (DS), a frequent inflammatory illness of the oral mucosa mostly related to denture wearing, is a major concern. DS is a common oral mycotic infection for those who wear partial or total dentures. The most often found species of Candida that may be isolated from both healthy and diseased oral tissues is Candida albicans. DS is associated with uneven denture surfaces, inadequate oral hygiene, or ill-fitting dentures. The diagnosis and management of DS in a 72-year-old male patient is presented in this case study. The patient complained about burning in his palate and having difficulty chewing. Upon clinical examination, erythema and inflammation were seen in the palate region. The history and clinical findings were consistent with DS. The patient was told to completely stop using dentures. Interventions were included in the treatment plan, such as diode laser therapy, topical ozonated oil application, and teaching about denture hygiene. The third day's follow-up visit revealed a progressive healing of the lesions and symptom relief. The lesion fully resolved on the sixth day. This case emphasizes the value of all-encompassing management techniques in treating DS successfully. It also highlights the significance of patient education, good oral hygiene, and focused therapy in producing favorable results.

High-frequency low-intensity semiconductor laser irradiation enhances osteogenic differentiation of human cementoblast lineage cells.

PURPOSE: Laser irradiation activates a range of cellular processes in the periodontal components and promotes tissue repair. However, its effect on osteogenic differentiation of human cementoblast lineage cells remains unclear. This study aimed to examine the effects of high-frequency semiconductor laser irradiation on the osteogenic differentiation of human cementoblast lineage (HCEM) cells. METHODS: HCEM cells were cultured to reach 80% confluence and irradiated with a gallium-aluminum-arsenide (Ga-Al-As) semiconductor laser with a pulse width of 200 ns and wavelength of 910 at a dose of 0-2.0 J/cm2. The outcomes were assessed by analyzing the mRNA levels of alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX2), and type I collagen (COLL1) using real-time polymerase chain reaction (PCR) analysis 24 h after laser irradiation. Cell mineralization was evaluated using ALP activity, calcium deposition, and Alizarin Red staining. RESULTS: The laser-irradiated HCEM cells showed significantly enhanced gene expression levels of ALP, RUNX2, and COLL1 as well as ALP activity and calcium concentration in the culture medium compared with the non-irradiated cells. In addition, enhanced calcification deposits were confirmed in the laser-irradiated group compared with the non-irradiated group at 21 and 28 days after the induction of osteogenic differentiation. CONCLUSION: High-frequency semiconductor laser irradiation enhances the osteogenic differentiation potential of cultured HCEM cells, underscoring its potential utility for periodontal tissue regeneration.

A mechanistic study on the toluidine blue/ photodynamic therapy inhibition of lipopolysaccharide-induced inflammatory response in rat gingival fibroblasts.

The purpose of this research was to investigate the effect of toluidine blue (TB) mediated photodynamic therapy (PDT) on the inhibition of lipopolysaccharide (LPS)-induced inflammation in rat gingival fibroblasts through in vitro experiments. Rat gingival fibroblasts were divided into five groups: (1) control, (2) LPS treatment, (3) laser treatment, (4) TB treatment (1.0 µg/mL), and (5) PDT treatment (TB plus laser irradiation at 320 mW/cm2 for 240 s). After 24 h, cell growth activity was measured using MTT assay. The levels of receptor activator for nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) in the cell culture supernatant were measured using enzyme-linked immunosorbent assay (ELISA). Nuclear proteins were extracted and the phosphorylation levels of phosphorylated nuclear factor-κB/p65 (p-p65) and phosphorylated inhibitor of nuclear factor-κB (p-IκBα) were determined using Western Blot. MTT results showed no significant difference in cell viability between the groups (P > 0.05). After LPS induction, OPG expression decreased, RANKL expression increased, and the OPG/RANKL ratio decreased, which was different from the control group (P < 0.05). After PDT treatment, OPG expression increased, RANKL expression decreased (P < 0.05), and the OPG/RANKL ratio increased (P < 0.05). Compared to the control group, there was no significant difference in OPG and RANKL expression or the OPG/RANKL ratio (P > 0.05). The activation of NF-κB was closely related to the phosphorylation levels of p-p65 and p-IκBα. LPS significantly up-regulated p-p65 and p-IκBα expression (P < 0.05), while PDT treatment decreased their phosphorylation levels (P < 0.05). TB-PDT treatment can inhibit NF-κB signaling pathway activation, decrease RANKL and OPG expression, and reduce the OPG/RANKL ratio, thereby reducing inflammation and playing a role in periodontitis treatment.

Exploring the efficacy of laser-assisted in-office tooth bleaching: A study on varied irradiation times and power settings utilizing a diode laser (445 nm).

The aim of this study was to evaluate the effectiveness of a laser-assisted in-office tooth bleaching treatment, employing a diode laser (445 nm) using different power and time settings. Two hundred human incisors were collected for evaluating tooth color change (ΔΕ00) and whiteness index in dentistry (ΔWID) following laser-assisted tooth bleaching treatment. The specimens were distributed into 25 groups (n = 8) according to laser output power (0.5-2 W) and duration of irradiation (10-60 s) that was applied. ΔΕ00 and ΔWID were evaluated using a spectrophotometer at three points of time (24 h, 1 week and 1 month after treatments). Three-way ANOVA revealed that power, duration of laser irradiation, and time of measurement after bleaching treatments significantly affected both ΔΕ00 and ΔWID(p < 0.05). Furthermore, laser irradiation increased ΔΕ00 and ΔWID at all applied powers compared to the control group (p < 0.05), but this increase was dependent on the duration of irradiation. Laser irradiation significantly increased ΔΕ00 when the duration of operation was 50-60 s at 0.5-1 W, while at 1.5-2 W was significantly increased when the duration was 30-60 s. ΔWID was significant higher in the laser groups compared to the control group at all powers, except for 0.5 W where it was significant higher when the duration was 50-60 s. The outcomes of the study can help in selecting the suitable power settings and duration of laser exposure to achieve the optimal whitening results while ensuring the safety of the tooth pulp.

The Effect of Two Different Wavelengths of Diode Laser on the Shear Bond Strength of Composite to Dental Enamel after Bleaching Process: An In Vitro Study.

INTRODUCTION: In recent years, tooth whitening has become one of the most popular ways of achieving the original tooth color. The effect of whitening gel can be improved through heat, light or laser. The bond strength between the enamel and the composite can be reduced through bleaching and laser radiation. The purpose of this study is to assess the shear bond strength of resin composite to enamel after a bleaching process using hydrogen peroxide, with and without a laser (970 nm and 445 nm lasers). METHOD: This study used 51 extracted anterior teeth without caries that were divided into three groups. A 40% hydrogen peroxide gel was used on the enamel of all teeth. The control group received bleaching without a laser. Both the second and third treatment groups received bleaching with a laser, one with 970 nm and the other with 445 nm. After the bleaching process, all groups had etching, bonding and curing of the composite performed. Lastly, the shear bond strength between the enamel and the composite was measured and the failure modes were recorded. The data were compared using a one-way ANOVA test. RESULTS: The mean shear bond strength between the enamel and the composite in the 445 nm group three (445 nanometer) was significantly lower than the other groups (p < 0.05). There was no significant difference between the control and the 970 nm groups (p = 0.2). CONCLUSION: According to the laser wavelengths and parameters that were used in this study and the results of this study, office bleaching with a 445 nm laser weakened the shear bond strength between the enamel and the composite.

Intraoral Applications of Lasers in the Prosthetic Rehabilitation with Fixed Partial Dentures-A Narrative Review.

Laser, an acronym for Light Amplification by Stimulated Emission of Radiation, is a powerful tool with diverse applications in modern dentistry. It emits monochromatic, coherent light resulting from photon-induced chain reactions. Available dental lasers include diode, argon, Er,Cr:YSGG, Er:YAG, Nd:YAG, and CO2. The unique property of these lasers, allowing them to be effectively used on both soft and hard tissues based on the operational parameters, positions them as particularly suited for a wide range of dental procedures. Compared to traditional methods, lasers offer advantages such as improved hemostasis and quicker wound healing. Such benefits stress the shift towards laser technology in dental treatment. In the realm of dental prosthodontics, which focuses on esthetics, functionality, and the physiological aspects of dental prostheses, lasers provide promising outcomes. Among the prosthetic options, fixed partial dentures stand out for their ability to mimic natural teeth, offering both esthetic and functional features, leading to satisfactory long-term outcomes if managed properly. This review paper delves into the specific application of laser technology in the context of prosthetic rehabilitation involving fixed partial dentures. By investigating intraoral laser procedures, it contributes to understanding laser's role in improving patients' satisfaction and clinical efficiency in this field.

Management of Lobular Capillary Hemangioma Using Diode Laser: A Case Report.

This case report focuses on the clinical development of a 32-year-old female patient's lobular capillary hemangioma and provides valuable insights into the atypical nature of this tumor. Low-level laser therapy (LLLT) that follows diode laser intervention can be regarded as a novel and evidence-based approach to therapeutic management. The application of a diode laser causes the vascular elements that comprise the bulk of the lesion to coagulate, which in turn causes the lesion's size to decrease. The biological processes that lead to quick tissue regeneration are also activated by LLLT. The suggested therapeutic approach ensures that the patient will heal in the best possible way while also optimizing their comfort and safety. It extends beyond the mere removal of wounds. The case report demonstrates how well dual laser therapy works to lessen common postoperative issues that are commonly seen in traditional surgical therapies for lobular capillary hemangioma such as excessive bleeding and infection. The precise application of the diode laser minimizes damage to surrounding tissues, thereby enhancing the healing process. Additionally, following surgery, LLLT helps reduce pain and inflammation, which improves patient outcomes. The potential of diode laser and LLLT therapies for treating vascular lesions, including lobular capillary hemangioma, is evidenced by their therapeutic advantages. This encourages wider clinical applications and field research. The presented case report offers valuable clinical significance by highlighting an innovative therapeutic approach for lobular capillary hemangioma, a vascular lesion that can present challenges in management.

Concomitant Prostate Needle Biopsy and Laser Vaporization of the Prostate Could Be a Risk of Postoperative Hemoglobin Decline, a Retrospective Study.

Purpose: Contact laser vaporization of the prostate (CVP) for benign prostatic hyperplasia is a widely accepted and safe procedure for elderly patients because of its lower bleeding risks. However, CVP lacks a postoperative pathological examination for prostate cancer. Concomitant prostate biopsy and CVP may complement this disadvantage; however, the risk of bleeding associated with this procedure remains unclear. This study aimed to evaluate the safety of a concomitant prostate biopsy and CVP. Patients and Methods: This retrospective study included 106 men who had undergone CVP in Nerima General Hospital. Prostate biopsies and CVP were performed simultaneously on 16 patients. We defined the "hemorrhage group" by a >5% decrease in hemoglobin the day after surgery. Preoperative and operative indices were evaluated based on the association with the hemorrhage group. Results: Participants in the concomitant biopsy group were older (p = 0.001), had larger prostates (p = 0.014), a lower rate of prostate biopsy history (p = 0.046), longer postoperative urinary catheter duration (p = 0.024), and a higher rate of decline in hemoglobin levels the day after surgery (p = 0.023). Patients in the hemorrhage group (n = 20, 18.9%) showed a significantly higher rate of concomitant biopsy and CVP (p = 0.006). Multivariate analysis showed that concomitant prostate biopsy (p = 0.009, odds ratio = 4.61) was the sole statistically significant predictive factor for hemorrhage. Conclusion: Concomitant prostate biopsy and CVP of the prostate may increase the risk of bleeding.

Longitudinal Mode Number Estimation of External Cavity Diode Laser Using Dual Periodic Grating for Optical Profiler System.

The concept of an optical profiler based on optical resonance was proposed, highlighting the initial requirements for mode number estimation. We proposed a method for estimating the longitudinal mode number of a laser propagating in an external cavity diode laser with high accuracy, utilizing dual-periodic diffraction gratings. These gratings were fabricated using interference lithography. To estimate the mode number, the wavelengths of two different modes are compared. Therefore, the greater the difference between the wavelengths, the higher the accuracy of the mode number determination. While the mode number difference was approximately 35 when using a conventional diffraction grating, this could be increased by a factor of 20 to around 700 using the dual-periodic grating. The relative accuracy achieved was 1.4 × 10-5.

The risk of bias was assessed using the ROBIS tool. Results: In total, 29 articles in PubMed, 75 in Scopus, and 61 in ISI Web of Science. Finally, only five systematic reviews were included. Conclusions: The results showed the range from 730 to 830 nm as the most effective range of wavelength to accelerate the orthodontic dental movement. A power range of 0.25-200 mW, with emphasis on the direct correlation between power, wavelength, and energy density. Energy density has not been adequately reported in the most randomized controlled clinical trials.

The Endo-lift Laser (Intralesional 1470 nm Diode Laser) for Dermatological Aesthetic Conditions: A Systematic Review.

BACKGROUND: The prominence of minimally invasive aesthetic approaches has become increasingly pivotal. The endo-lift laser method is an intralesional 1470 nm diode laser connected to a fiber that serves both therapeutic and aesthetic properties. We sought to evaluate the efficacy and safety of the endo-lift laser method for dermatological aesthetic applications. METHODS: PubMed, Ovid-Embase, and Web of Science were systematically searched up to November 5th, 2023. A citation search was also performed. The National Institute of Health (NIH) Quality Assessment Tool was used to evaluate the quality of the studies. RESULTS: Out of 339 articles, twenty-three relevant studies were included in the current review. Applying the endo-lift laser method for rejuvenation, including face and neck lifting, enhancing skin laxity, and disappearing wrinkles, folds, and lines, demonstrated favorable efficacy and safety profile. Moreover, most studies have shown that the endo-lift laser method is promising in eliminating the adipose tissue in the jowl, abdomen, thighs, and arms. The endo-lift laser technique was also efficacious in nose remodeling and blepharoplastic procedures, including treating eyelid and eyebrow ptosis, eye bag, eyebrow position, and eyelid laxity. Patients who suffer from several diseases, such as hidradenitis suppurativa, progressive lipodystrophy, acne vulgaris, scars, and keloids, benefit from procedural treatment with the endo-lift laser technique. Across all studies, the adverse events were mild and self-limiting. Investigating the endo-lift laser method in all aesthetic and therapeutic indications resulted in high patient satisfaction rates. CONCLUSION: The endo-lift laser technique has therapeutic effects and is recommended for various dermatological aesthetic indications. Further clinical studies with control groups and larger sample sizes are needed to acquire more reliable evidence.

Background: Intentional replantation (IR) is an emerging and cost-effective last-resort treatment for persistent apical periodontitis. Adjunctive phototherapy for IR aims to improve the management of challenging cases by enhancing disinfection, stimulating healing and promoting regeneration. Objective: We report a novel phototherapy-assisted IR protocol conducted on a compromised lateral incisor with an extensive periapical infection (Ø > 10 mm) in a 68-year-old diabetic male. Methods: The IR protocol involved pre- and postoperative photobiomodulation (660 nm, 0.2 J/cm2, 60 sec/site), antimicrobial photodynamic therapy of the root surface (660 nm, 0.6 J/cm2, 30 sec, methylene blue photosensitizer), and Er:YAG root and socket debridement (2940 nm, 21 J/cm2, 30 sec). The total time from extraction to replantation was 14 min 35 sec. Results: The tooth at 3.5-year follow-up remained clinically functional with radiographic resolution of the infection indicating a successful reimplantation. Conclusions: This case report demonstrated that an adjunctive phototherapy IR protocol can effectively treat a compromised tooth with extensive periapical infection.

Efficacy of a novel low-cost torchlight transcorneal transillumination for diode laser transscleral cyclophotocoagulation in adult glaucoma.

PURPOSE: To study the outcomes of diode laser transscleral cyclophotocoagulation (TSCPC) with trans-corneal transillumination using a novel low-cost torchlight method in refractory glaucoma. METHODS AND ANALYSIS: This prospective interventional study included patients with refractory glaucoma who underwent TSCPC with trans-corneal transillumination (TSCPC-TI) using a novel low-cost torchlight method. Patients completing a minimum 6-month follow-up were analyzed. They were compared to a historical control group of patients who underwent TSCPC without transillumination (TSCPC-No TI) at 6-month follow-up period. We analyzed the mean laser energy delivered, post-laser intraocular pressure (IOP) reduction, number of antiglaucoma medications (AGM), the requirement of retreatment and complications of the procedure in both groups. RESULTS: 32 eyes of 29 patients comprised the TSCPC-TI group and were compared with 39 eyes of 37 patients in the TSCPC-No TI group. The TSCPC-TI group required lower energy than the TSCPC-No TI group (46.15 ± 22.8 Vs 80.65 ± 56.1 J p < 0.001). At 6-month follow-up, the TSCPC-TI group required lesser AGM for IOP control (2.33 ± 1.02 vs 3.02 ± 1.32 p = 0.01). There was a significantly reduced dependence of oral acetazolamide in the TSCPC-TI group at 6 months follow-up (15.6% vs 41% p = 0.03%). The success and response rates were 71.8% Vs 23.1%; p < 0.0001 and 87.5% Vs 51.2%; p = 0.001 significantly high in the TSCPC-TI group. The TSCPC-No TI group had a significantly high failure rate (12.5% Vs 48.2% p = 0.001). Hypotony (n = 1) and phthisis (n = 2) were noted TSCPC-No TI group. CONCLUSIONS: TSCPC with transillumination with a low-cost torchlight resulted in a more efficient and effective cycloablation than TSCPC without transillumination.
