Oral candidiasis is a common problem among immunocompetent patients. The frequent resistance of Candida strains to popular antimycotics makes it necessary to look for alternative methods of treatment. The authors conducted a systematic review following the PRISMA 2020 guidelines. The objective of this review was to determine if curcumin-mediated blue light could be considered as an alternative treatment for oral candidiasis. PubMed, Google Scholar, and Cochrane Library databases were searched using a combination of the following keywords: (Candida OR candidiasis oral OR candidiasis oral OR denture stomatitis) AND (curcumin OR photodynamic therapy OR apt OR photodynamic antimicrobial chemotherapy OR PACT OR photodynamic inactivation OR PDI). The review included in vitro laboratory studies with Candida spp., in vivo animal studies, and randomized control trials (RCTs) involving patients with oral candidiasis or prosthetic stomatitis, published only in English. The method of elimination of Candida species in the studies was curcumin-mediated aPDT. A total of 757 studies were identified. Following the analysis of the titles and abstracts of the studies, only 42 studies were selected for in-depth screening, after which 26 were included in this study. All studies evaluated the antifungal efficacy of curcumin-mediated aPDT against C. albicans and non-albicans Candida. In studies conducted with planktonic cells solutions, seven studies demonstrated complete elimination of Candida spp. cells. The remaining studies demonstrated only partial elimination. In all cases, experiments on single-species yeast biofilms demonstrated partial, statistically significant inhibition of cell growth and reduction in biofilm mass. In vivo, curcumin-mediated aPDT has shown good antifungal activity against oral candidiasis also in an animal model. However, its clinical efficacy as a potent therapeutic strategy for oral candidiasis requires few further RCTs.

The aim of the study was to measure the degree of dentine surface roughness caused by five distinct lasers used to treat dentine hypersensitivity, as well as to evaluate the subsequent bacterial colonization on these irradiated surfaces. Sixty human maxillary premolar teeth without caries or restoration which were extracted for periodontal reasons were used in this study. Five different types of lasers were applied to the root dentin surface. Tested samples were divided into six groups of 10 samples each; control, diode (810 nm), diode (980 nm), Nd: YAG, Er: YAG, and Er, Cr: YSGG laser groups. The arithmetic mean of the surface roughness values (Ra) and the average roughness over a measurement area (Sa) were measured pre- and post-application using any of the laser types. Swab samples were then collected from the dentin surface. Following a 24-hour incubation period at 37 °C, the colony forming units were counted using a stereoscope. The results demonstrated a statistically significant difference in the surface roughness values pre- and post-application (Ra and Sa, respectively) in the Er, Cr: YSGG laser group (p = 0.037,p = 0.007). No significant difference was observed in the other groups (p > 0.05). There was no statistically significant difference in the number of bacterial colonies observed between the test and control groups. Diode and Nd: YAG lasers showed either a decrease or no change in surface roughness; however, the hard tissue lasers (Er: YAG, Er, Cr: YSGG) showed an increase. The Er: YAG and Nd: YAG laser groups exhibited decreased bacterial adhesion compared to the other groups.

OBJECTIVE: To assess both the clinical and immunological effectiveness of diode laser therapy when used as an adjunct to non-surgical mechanical therapy in managing peri-implantitis.
METHODS: A cohort of 27 participants, comprising 21 females and 6 males, agreed to take part in this investigation. 37 dental implants with peri-implantitis diagnosis were randomly allocated to either the laser group (n = 19) or the control group (n = 18). Evaluation of peri-implant clinical parameters and collection peri-implant crevicular fluid (PICF) samples occurred at baseline, as well as at 3 and 6-month follow-up intervals. The level of various biomarkers (TWEAK, IL-1β, sclerostin, IL-17, RANKL, OPG and IL-10) within the PICF were quantified using enzyme-linked immunosorbent assay.
RESULTS: Significant time-dependent decreases in clinical and biochemical parameters were detected in both groups compared to the baseline. There were marked differences between the groups in terms of periodontal parameters, except probing depth, and IL-1β, IL-17, sclerostin levels in PICF at 3rd month follow-up. However, no statistically significant difference was detected at 6th month.
CONCLUSIONS: Diode laser seems to be a reliable tool as an adjunct for supporting the nonsurgical mechanical treatment during the early stages of peri-implantitis. Furthermore, the findings suggest that IL-17, sclerostin and IL-1β may serve as promising biomarkers for assessing efficacy of peri-implantitis treatment.
CONCLUSIONS: Based on these outcomes, clinicians may consider the application of adjunctive use of diode laser to non-surgical peri-implantitis treatment to achieve better clinical and immunological improvements than nonsurgical peri-implantitis therapy alone in just early healing period. However, it should be noted that there was no difference between the two methods in the long term.

Maxillary labial frenectomy is a surgical procedure aimed at addressing midline diastema, where a strip of tissue creating a gap between two upper front teeth is removed. Typically, this strip extends from the vestibule of the gingivobuccal sulcus to the attached gingiva. The procedure is often performed using a diode laser, offering benefits including simplicity and safety for the patients. It can remarkably improve overall aesthetics and decrease the chances of gingival recession. This case report highlights the successful management of a female patient who arrived complaining of double frenum attachment leading to poor musculature support due to which she experiences poor aesthetics and hampered oral hygiene maintenance.

Median diastema is a physiological occurrence that is frequently seen in the maxillary jaw. Therefore, a median diastema has been associated with a wide range of etiological variables, including thumb sucking, supernumerary teeth, tongue thrusting, some dentoalveolar discrepancy, and hypodontia. Patient esthetic and function demands are both negated by the labial frenum\'s abnormal location in relation to the maxillary anterior teeth, which results in diastema and gingival recession. Lasers are now being used in several fields of dentistry as an alternative to conventional scalpel operations. Frenectomy can be done through the use of electrosurgery, laser surgery, or the classic scalpel technique. This pathological frenum can be very well excised with a diode laser. Due to its applicability, sufficient coagulation, lack of suture requirements, and reduced discomfort and inflammation, the diode laser can be utilized in pediatric dentistry. High-connected midline diastema has remained a subject of debate when it comes to management and the right time to intervene and treat it. Both orthodontists and pediatric dentists agree that frenectomy should not be done after the closure of the orthodontist gap or before the appearance of the permanent canine teeth. However, several conditions, including the child\'s psychological status, parents\' concerns, the closure\'s unpredictable effects on the future, and the expense of combined therapies, may lead to an early intervention for therapy during the primary or mixed dentition. In this specific scenario, a child who was eight years old underwent a diode laser frenectomy. After seven days, a follow-up examination showed normal position and attachment of the frenum and no signs of infection at the site of surgery.

During the first several weeks following lactation, nipple pain frequently prevents mothers from continuing breastfeeding. To evaluate the efficacy of using Photobiomodulation (PBM) versus anti-inflammatory topical cream, on inflamed nipple, and the effect on milk production. This study was carried-out on 50 breastfeeding women with nipple pain and fissure. Our patients were divided into two groups ; study group (Group I): 25 patients received 12 sessions of PBM using Diode laser for a period of 4 weeks, 3 sessions per week every alternative day, and controlled group (Group II): 25 patients used Anti-inflammatory topical cream. Regarding inflammatory signs in both groups, Group I showed a significant decrease in redness compared to Group II at the 3rd and 4th week, and a significant decrease in nipple fissure and pain at the 3rd week. There was a significant increase in milk amount reflected on the infant\'s weight. We concluded that PBM was more effective in decreasing nipple pain, inflammation and subsequently milk production and infant weight than topical anti-inflammatory creams.

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.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.

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.
CONCLUSIONS: 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.
BACKGROUND: This clinical trial was registered on Clinical Trials.gov (Registration ID: NCT06209554) and released on 08/01/2024.
