Aim of the study: To evaluate the effect of low-level laser therapy, as an adjunct to non-surgical periodontal treatment, on periodontal clinical and biochemical parameter i.e CRP. Materials and Methods: The study was designed as a randomized, controlled, single-blind, split-mouth clinical trial. Systemically healthy persons diagnosed with chronic periodontitis and presence of at least two bilateral maxillary premolars with ≥5-mm periodontal pocket depth were included in the study. The PPD, CAL,MGİ and SBI were measured at the baseline and at 1 and 3 months after periodontal treatment. Gingival crevicular fluid samples were taken at the baseline , 1 month and 3 months after treatment. The LLLT application was made in four sessions: after periodontal treatment, on the third day, and on the seventh day post-treatment. LLLT was applied in non-contact mode and tip tissue distance was approximately 1cm on every tooth on the test side for 15 s in the continuous mode, at 0.5 W and with an application tip 1 cm in diameter. Results: Intra group comparison for both the groups showed significant difference from baseline to one month for MGI and SBI and PD showed significant difference only in the test group , whereas from baseline to three months all the parameters showed statistically significant difference. Intergroup comparison between the groups showed statistically significant differences between MGI, SBI and CRP levels. Conclusion: Within the limitations of this study, LLLT in addition to non surgical periodontal treatment, has positive impact.

Introduction: Conventional periodontal therapy in form of scaling and root planing (SRP) has its own limitations when used in deep pockets. Various studies have reported adjunctive use of laser therapy as a promising modality to overcome limitations of SRP. Aim and Objectives of the Study: The aim of this study was to assess the adjunctive effect of 810-nm diode laser on clinical parameters and prostaglandin E2 (PGE2) levels in gingival crevicular fluid (GCF). Materials and Methods: The present study was a split-mouth clinical study, which included 48 sites from patients diagnosed with moderate-to-severe chronic periodontitis. Test group consisted of 24 sites that received diode laser (810 nm, 2.5 W) therapy as an adjunct to SRP whereas control group consisted of 24 sites, which received SRP only. Gingival index (GI) was assessed clinically whereas Florida Probe was used to record bleeding on probing (BOP), pocket probing depth (PPD), and clinical attachment level (CAL) at baseline, 3 months, and 6 months. GCF PGE2levels were measured at baseline and 3 months post therapy using commercially available ELISA kit (Neogen™). Results: Test group showed a significant reduction in GCF PGE2levels at the end of 3 months when compared to control sites. However, the primary clinical parameters (CAL and PPD) from baseline to 3 and 6 months did not show statistically significant improvement in the test group. Conclusion: Application of diode laser resulted in a significant reduction in PGE2levels compared to SRP alone. Thus, diode laser therapy as an adjunct to SRP appears to be a promising treatment modality to reduce or modify the host response.

The most common developmental anomaly of the tongue is ankyloglossia which is characterized by a short, thick lingual frenum resulting in limitation of tongue movement, speech problems, and feeding problems in neonates. Failure in early diagnosis of this anomaly results in social communicating and mechanical problems in an individual. If clinicians diagnose and treat this in early childhood by frenectomy, speech problems can be overcome by speech therapy, but due to ignorance of individual's parents and by clinician, sometimes this anomaly remains undetected and produces speech problems throughout the life. In spite of the treatment in an adult individual of an ankyloglossia, speech therapy rarely improves individual's speech problems. This is a case report of an ankyloglossia treatment by a diode laser in an adult.

Aim of the Study: The aim of this present study is to evaluate the knowledge level about laser systems in dentistry of practitioners who educated/continuing education in dental faculties in Kırıkkale and Ankara, Turkey. Materials and Methods: This cross-sectional, descriptive study was carried out at the Faculty of Dentistry, Kırıkkale University, in Turkey. In this study, totally, 130 participants were evaluated. Seventy-six of them (17 males and 59 females) were in Ankara and 54 participants (18 males and 36 females) were in Kırıkkale. A survey which consists of 17 questions was conducted through face to face. The obtained data were statistically evaluated using the Chi-square test of SPSS program. Results: At the end of the study, it has been determined that 87.2% of the participants have knowledge about dental laser systems while 12.3% have no information on this subject. This percentage was 81.6% in Ankara and 96.3% in Kırıkkale separately. No statistically significant difference was found comparing the knowledge level of participants regarding cities educated. Conclusion: Since there is limited research available in the literature which investigated the education level on this subject, it can be claimed that the result of this study may be supported this field. This emphasizes that we need to focus more on this and that more research needs to be done.

The color of normal gingiva depends on the vascular supply of the gingiva, epithelial thickness, degree of keratinization of the epithelium, and the presence of pigmented cells. Excessive gingival display and gingival hyperpigmentation are major concerns for a large number of patients visiting the dentist. The foremost indication for depigmentation therapy is the demand by a patient for improved esthetics. This case report represents a correction of gingival hyperpigmentation by diode laser with satisfactory and pleasant results.

Objective: A pyogenic granuloma (PG) is a lesion similar to a reactive, inflammatory, benign tumor of the skin and mucous membrane. An oral PG develops due to pregnancy, hormonal status, poor oral hygiene, chronic irritation, and trauma. The aim of this study was to compare bleeding quantities, postoperative pain levels, and relapse rates of excisional biopsies performed either with standard surgical techniques for PGs or their removal with a laser biopsy performed with a diode laser. Materials and Methods: In this controlled, randomized, clinical study, 14 patients who were systematically healthy and with a gingival growth similar to a PG were assigned to one of two groups. In the first group, the biopsy procedures were performed with diode lasers (Epic, Biolase, Irvine, CA, USA) (810-nm wavelength, 10 W power). In the second group, the biopsies were performed with conventional surgical techniques using scalpels. The intraoperative bleeding quantities were determined in accordance with the criteria defined by the World Health Organization. The postoperative pain levels were evaluated with a visual analog scale (VAS). The patients were evaluated with regard to their relapse status, which may have occurred up to 6 months following the procedure. Results: During the operation, in the first group, the bleeding quantities were significantly lower. For the VAS values, a significant difference between the groups was not observed. In the second group, a recurrence was observed in two patients; however, in the first group, there were no recurrences. Conclusion: Compared to conventional surgical treatments, the advantages of the diode laser as an alternative treatment may include decreased blood loss during the operation and a decreased possibility of relapse.
目的:化脓性肉芽肿(PG)是一种类似于皮肤和粘膜反应性炎性良性肿瘤的病变。口腔PG的发生是由于怀孕、激素状况、口腔卫生不良、慢性刺激和创伤所致。本研究的目的是比较PGs的标准手术技术和激光活检的出血量、术后疼痛水平和复发率。材料和方法:在这项对照、随机的临床研究中，14名全身健康且牙龈生长与PG相似的患者被分为两组。在第一组中，使用二极管激光器(Epic, Biolase, Irvine, CA, USA) (810 nm波长，10 W功率)进行活检。在第二组中，使用手术刀进行常规手术技术的活检。术中出血量按照世界卫生组织规定的标准测定。采用视觉模拟评分(VAS)评估术后疼痛水平。对患者的复发状态进行评估，复发可能发生在手术后6个月。结果:手术过程中，第一组出血量明显减少。VAS评分组间差异无统计学意义。在第二组中，有2例患者出现复发;然而，在第一组中，没有复发。结论:与常规手术治疗相比，二极管激光作为替代治疗的优势在于术中出血量减少，复发可能性降低。

Background: Dentinal hypersensitivity (DH) is characterized by a nonspontaneous, an acute short- or long-lasting pain originating from exposure of the dentinal tubules or dentine to the thermal, chemical, mechanical, or osmotic stimuli, which cannot be attributed to any other dental pathology. There are a lot of treatments; one of these is lasers. Laser therapy was first introduced as a potential method for treating DH in the mid-1980s. Various types of laser used in treatment include low-power lasers He-Ne (632.5 nm), diode lasers (DLs) with various wavelengths 810, 940, and 980 nm, and medium-power lasers as Nd:YAG (1064 nm), CO2 (10600 nm), Er:YAG (2940 nm), and Er, Cr:YSGG (2780 nm). He-Ne (632.5 nm) and DLs have analgesic effect; they can have effect alone or with combination with desensitizing agents. Aim of Study: To appraise and assess the efficiency of different techniques using DLs 810 and 980 nm alone or in combination with different desensitizing agents in the management and treatment of DH. Materials and Methods: A total of 138 articles are included; then, according to exclusion criteria, 46 articles are included; after specific exclusion criteria and evaluation of the articles, they become 35 articles. Regarding exclusion criteria as some titles are not related to the title of literature and discuss other issues, from the 35 articles, there were five systematic review articles and 22 in vivo and 8 in vitro studies. Results: 980 nm and 810 DLs are effective in reduction or treatment of DH alone or in combination with desensitizing agents. DLs and in combination with desensitizing materials are very efficient and precise than treatment done by DLs alone; there is no effect on the pulp tissue as the temperature does not exceed the threshold temperature (5.5°C). Conclusion: 810 and 980 DLs are effective in the treatment and reduction of DH, DLs with different wavelengths alone or with desensitizing materials are efficient, and there is no effect on the pulp tissue as the temperature does not exceed the threshold temperature.

Esthetics has become a major concern in the modern era, though hyperpigmented of gingiva is not a medical problem, many people consider it as unesthetic. Gingival melanin pigmentation occurs in all races without any sex and gender predilection in variable amount caused by melanin granules. The degree of pigmentation varies from individual to individual based on various etiological factors. The gingival hyperpigmentation is removed or reduced by various techniques such as scalpel, electrosurgery, cryosurgery, lasers, and abrasion with diamond bur. The present study compares the management of three cases with scalpel, electrocautery, and laser techniques.

Introduction: Conventional chemomechanical debridement (CMD) of deciduous root canals can significantly reduce the intracanal bacterial load but cannot assure predictable disinfection due to the inherent anatomical complexities. Newer methods are thus being employed to enhance the efficacy of pediatric endodontic disinfection, and the use of laser technology is at the forefront of this endeavor. Aim: The aim is to assess the efficacy of diode laser-assisted disinfection in comparison to conventional sodium hypochlorite (NaOCl) based CMD in deciduous root canals. Materials and Methods: A total of 12 patients aged 5–8 years of both genders were selected. Local anesthesia was administered and rubber dam isolation achieved. Access opening was done and the roof of the pulp chamber was removed. A sterile paper point compatible with the anatomic diameter of the canal was introduced and left in place for 30 s ( first sample) which was then transferred into an Eppendorf tube containing reduced transport fluid medium. CMD was performed up to 25 number K-file with intermittent 3% NaOCl irrigation. Post-CMD, sterile number 25 paper points were introduced as above (second sample). Thereafter, an 810 nm diode laser (1W, CW) with a specific endodontic E-200 tip was introduced into the root canals 2 mm short of the radiographic apex and was gently withdrawn in a helical zigzag motion. Another sample was then taken using a sterile No. 25 paper point (third sample) and transported to the microbiological laboratory for culture. Results: The mean reduction in colony forming units postdiode laser application was seen to be 100% when compared to 98.46% reduction after CMD with 3% NaOCl. Conclusion: An 810 nm diode laser can be used as an effective adjunct to conventional methods of deciduous root canal disinfection.

Conclusion: An 810 nm diode laser can be used as an effective adjunct to conventional methods of deciduous root canal disinfection.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116176088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The objective of this study was to evaluate the efficacy of laser fluorescence (LF)-based diagnostic device for monitoring the effect of aluminum gallium arsenide (Al Ga As) laser on noncavitated enamel lesions. Background: Dental caries is a reversible disease, and scope of reversing the carious lesion is increased if it is diagnosed before there is surface cavitation. Variegated remineralization strategies including remineralizing pastes and different lasers have been explored. The efficacy of this surface treatment requires a valid and a reliable assessment tool. LF is one such adjunct to traditional methods of caries detection. Materials and Methods: Twenty-five intact freshly extracted molars were sectioned mesiodistally so as to obtain fifty samples which were coated with nail varnish so that 3 mm × 3 mm of windows are created to maintain uniformity. All sample surfaces were evaluated with LF device so as to obtain the baseline values, these values served as control. All the samples were then acid etched by 30% phosphoric acid for 20 s to simulate surface demineralization. The LF device was used to record the values of demineralized samples. The surfaces of the teeth were then irradiated with Al Ga As laser of 3.5 W for 30 s. The LF device was then used to record the reading. Statistical Analysis Used: Statistical analysis was done using paired t-test to compare control and test groups and calculation of the mean. Results: The demineralized surfaces have recorded statistically significant LF values greater than the untreated control sample values. Post laser irradiation, there is fall of the LF values and these values are closer to that of control. Conclusion: Laser fluorescence can be used as a tool to detect demineralization in situ and monitor changes in enamel surface during demineralization and remineralization phases. Surface treatment with laser irradiation gave values closer to that of control and this does indicate that laser irradiation brings about surface alteration as evaluated by laser fluorescence.
目的:评价激光荧光(LF)诊断装置监测砷化铝镓(Al Ga As)激光对牙釉质非空泡病变的疗效。背景:龋齿是一种可逆性疾病，如果在出现表面空化之前就诊断出来，则可增加逆转龋齿病变的范围。不同的再矿化策略，包括再矿化膏和不同的激光器已被探索。这种表面处理的效果需要一个有效和可靠的评估工具。LF就是传统的龋齿检测方法的辅助手段之一。材料与方法:对25颗新鲜取出的完整磨牙进行中向切片，获得50颗样本，并涂上指甲油，形成3mm × 3mm的窗口以保持均匀性。用LF仪对所有样品表面进行评估，获得基线值，这些值作为对照。然后用30%磷酸酸蚀20 s模拟表面脱矿。使用LF装置记录脱矿样品的数值。然后用3.5 W的Al - Ga - As激光照射牙齿表面30 s。然后使用LF设备记录读数。使用:采用配对t检验进行统计分析，比较对照组和试验组，计算平均值。结果:脱矿表面的LF值比未处理的对照样本值有统计学意义。激光照射后，LF值有所下降，且更接近对照组。结论:激光荧光技术可作为牙釉质脱矿原位检测和牙釉质脱矿和再矿化阶段牙釉质表面变化的监测工具。激光照射表面处理得到的数值更接近于对照，这表明激光照射引起了激光荧光评价的表面改变。
