Irritation fibroma is the most common tumor-like and submucosal reactive lesion in the oral cavity that composed of fibrous or connective tissue causing by traumatic irritants such as calculi, foreign bodies, chronic biting, overhanging margin restoration, sharp spicules of bones, and overextended borders of appliances. It is a well-defined lesion, slow in growth, and can occur in any age group but is more prevalent in the third, fourth, and fifth decades with a female predilection. The tumor may be small or may increase to several centimeters in diameter. The tumor may become irritated and inflamed and sometimes may even show ulcers, which is superficial in nature. The lesions are nonsymptomatic, and the patient usually reports for treatment due to the problem and discomfort during mastication. The fibroma appears as a nodular growth mainly on the buccal mucosa along the occlusal plane. Other common sites are the gingiva, palate, lips, and the tongue. The management of this reactive lesion can be done through conservative surgical approach.

Aim: This study aims to assess the attitude, awareness, and knowledge of the dental professionals regarding dental lasers in India. Materials and Methods: This survey was conducted at the 69th Indian Dental Conference, 2016, after approval from the organizing committee. Three-hundred copies of the questionnaire were distributed among the practitioners attending the conference. The questionnaire consisted of 23 questions. The first part of the questionnaire was about dental laser education and the second part was about the knowledge of dental laser applications. The second part was divided into six subsections. Each section consisted of several items related to the uses of laser in five different dental specialties in addition to a section on laser protection. Results: Only 21% of the respondents had received any formal training before the use of lasers. Most of the participants had insufficient knowledge regarding the applications of laser in dentistry. Students' knowledge of the uses of dental laser in periodontics, oral surgery, and operative dentistry was better than their knowledge in pediatric dentistry, orthodontic, and endodontics. Conclusion: The results of this survey suggest that there is a need to educate and train dental professionals regarding dental lasers to utilize this new technology to its full potential in future.

Aim: The purpose of this prospective clinical study was to compare the clinical efficacy of diode laser and topical 0.4% stannous fluoride (SnF2) gel in the management of dentinal hypersensitivity (DH). Materials and Methods: A total of 8 patients contributing 200 teeth with DH were enrolled in the study. The sensitive teeth were randomly allocated into 4 groups of 50 each: Group I teeth were treated with 0.4% SnF2 only; Group II with 0.4% SnF2 and diode laser irradiation in continuous, noncontact mode; Group III with diode laser only in continuous, noncontact mode; and Group IV with SnF2 and diode laser in continuous, contact mode. Pain/sensitivity was recorded using the visual analog scale before treatment, 10 min after treatment and 7, 15, and 30 days posttherapy.Results: All the groups showed significant reduction in DH. However, the use of both 0.4% SnF2 and diode laser in contact and noncontact mode showed statistically significant reduction in sensitivity (P < 0.001) when compared to SnF2 gel and diode laser alone. Conclusion: The adjunctive use of diode laser with SnF2 appears to be a promising treatment alternative in alleviating sensitivity.

Ankyloglossia is defined as a condition in which the tip of the tongue cannot be protruded beyond the lower incisor teeth because of a short lingual frenulum. The prevalence of ankyloglossia is 4.8%. An unusually short lingual frenum results in complications in speech, oral hygiene, lingual recession, etc. To have a healthy lifestyle, treatment becomes necessary. Lingual frenectomy is the treatment of choice. With the advent of lasers, the treatment has become simple, precise, and less discomfort compared to the conventional. The present case report deals with the treatment of ankyloglossia using 980 nm diode laser.

Pyogenic granuloma (PG) is an inflammatory hyperplasia of the tissues that occurs as a result of various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. The term used is a misnomer since it is unrelated to infection and does not contain pus. Clinically, oral PG develops as a solitary, granuloma-like, pedunculated, and easily bleeding tumor which mostly affects the gingiva followed by buccal mucosa, tongue, lips, and palate. It is also known as granuloma pyogenicum, granuloma gravidarum, telangiectatic granuloma, pregnancy tumor, vascular epulis, benign vascular tumor, and hemangiomatous granuloma. Females are affected more commonly mainly during puberty, pregnancy, and menopause probably due to the vascular effects of the hormones. The lesions are known as “pregnancy tumor” and tend to occur more frequently during the second and third trimesters. Commonly involved treatment protocols include conventional surgical excision, electrocautery, and lasers. The purpose of this article is to report the laser-assisted management of an unusual case of PG in a 22-year-old female patient in her 9th month of pregnancy.

Background: The advantage of laser use in medicine has been exciting and remarkable since its introduction in the 1960s. Several medical specialties use lasers in their daily practice; the excitement of this new technology has also reached dentistry, where over the past few years, the industry has developed lasers for intraoral use and has marketed them heavily, often relying on anecdotal evidence to support their claims of superior results with the use of lasers over conventional surgical treatment. Aim of Study: The study aimed to survey the attitude of dentists about laser and its interactions with tissue giving a near vision on the future of laser devices and its market in Egypt. Materials and Methods: A study carried on 15 dentists and they asked to answer a questionnaire of 22 questions about laser. Results: Regarding the question asked about knowing the dentists who have laser devices at their clinics in Egypt, all answered that they know 1–5 dentists only. Conclusion: Dentists have no enough motivation as they think that laser device in comparison with its limited uses in dental clinic is expensive and also spare parts are hard to gain or not available.

Peripheral ossifying fibroma (POF) is a nonneoplastic enlargement of the gingiva precipitated by local irritation and minor trauma. POF represents 9.6% of all gingival tumors and 3.1% of the oral lesions which are biopsied. Dental calculus, plaque, microorganisms, dental appliances, and restorations are considered to be examples of etiological factors. A 38-year-old female patient presented with a chief complaint of swelling in her upper front teeth region for 6 months. Examination revealed a nontender oval, sessile growth with respect to tooth number 21, 22 region, measuring approximately 2 cm × 1.5 cm × 1.5 cm in size with a pinkish red overlying mucosa without any ulcerations. Palpation revealed a sessile base with firm consistency. Based on these clinical, radiological, and histopathological findings a final diagnosis of POF with respect to 21, 22 region was made. The treatment consisted of scaling and root planning followed by complete excision of the lesion using a combination technique of using both surgical scalpel and diode laser. The patient was followed up for 1 year and there were no signs of recurrence. This case of excision with the combination of scalpel and laser and the absence of recurrence over a period of 1 year makes this novel approach a promising treatment option.

Background: The aim of this study was to estimate the random blood sugar (RBS) level from gingival crevicular blood (GCB) and finger-prick blood and to evaluate the effectiveness of scaling and root planing (SRP) with the adjunctive use of diode laser (DL) and antibiotics in chronic periodontitis (CP) patients with diabetes. Materials and Methods: A total of 60 patients were included in the study and divided into three groups, 20 in each group. SRP, SRP with adjunctive use of antibiotic, and SRP with adjunctive use of DL were done in patients belonging to Groups A, B, and C, respectively. Results: The RBS values were significant in all the three groups at baseline, 1 month, and 3 months. GCB values were significant only in Group B and Group C at baseline, 1 month, and 3 months. Data obtained from all three groups have revealed a strong correlation in the posttreatment reduction of glucose levels in GCB and blood sample obtained using finger-prick method. Conclusions: The results show that DL treatment can provide better clinical results when used as an adjunct to nonsurgical periodontal treatment in CP patients with diabetes. Moreover, less invasive technique to measure patient's blood glucose level aids the periodontist to better assess the glycemic control which, in turn, contributes to the success of periodontal therapy. On the basis of the results of this study, GCB is a useful aid for testing blood glucose during routine periodontal therapy.

Aim: The aim of this study is to determine the effectiveness of the irrigation techniques including Vibringe Sonic Irrigation, passive ultrasonic irrigation (PUI), photon-induced photoacoustic streaming (PIPS), and conventional needle irrigation (CNI) used to remove the calcium hydroxide (CH) from the artificial groove. Subjects and Methods: Ninety-four teeth extracted human mandibular premolars having single root and linear canal were instrumented with ProTaper system up to size 50. As a standard groove model was designed in the apex of the root's half part. The samples were divided into four experimental groups (n = 21). The techniques were applied for experimental groups as Vibringe (Group 1), PUI (Group 2), PIPS (Group 3), and CNI (Group 4). The residual amount of CH was measured with a stereomicroscope at × 15 magnification by scoring system. The obtained data were statistically analyzed by Kruskal–Wallis and Mann–Whitney U-tests (P < 0.001). Results: CH residues in Group 3 (PIPS) and Group 2 (PUI) were statistically significantly lower than those in Group 1 (Vibringe) and Group 4 (CNI) (P < 0.001). There was no statistically significant difference either between PIPS and PUI groups (P > 0.001) or between Vibringe and CNI groups (P > 0.001). Conclusions: PUI and PIPS techniques could remove but not clean up CH residues from the artificial grooves. In addition, the sonic irrigation technique through the Vibringe device was similar to CNI method in the effectiveness of removal of CH in root canal apices.

Background and Aim: This study evaluated and compared the immediate and 2-month desensitizing efficacy of Gluma Desensitizer, Seal and Protect sealant, fluoride varnish, and erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser in reducing cervical dentin hypersensitivity (DH). Materials and Methods: Sixty patients each with at least one hypersensitive premolar were selected and randomly assigned to four groups: Gluma Desensitizer, Seal and Protect sealant, Duraphat fluoride varnish, and Er,Cr:YSGG laser. The assessment method used to quantify sensitivity was the cold air syringe, and the sensitivity was recorded by the visual analog scale (VAS), before treatment (baseline), immediately after treatment, and after 1, 2, 3, and 8 weeks. Results: The study results showed that there was a significant reduction in sensitivity at the various time intervals with all the four desensitizing agents – glutaraldehyde in methacrylate resin (Gluma Desensitizer), nanofilled methacrylate resin (Seal and Protect), sodium fluoride varnish (Duraphat), and Er,Cr:YSGG laser therapy. Conclusion: It can be concluded that after 8 weeks of clinical evaluation, all therapies showed lower VAS sensitivity values compared with baseline, independently of their different modes of action. The study indicates that Er,Cr:YSGG laser can emerge as an efficient treatment alternative in the reduction of DH.

Verma","doi":"10.4103/JDL.JDL_5_18","DOIUrl":"https://doi.org/10.4103/JDL.JDL_5_18","url":null,"abstract":"Background and Aim: This study evaluated and compared the immediate and 2-month desensitizing efficacy of Gluma Desensitizer, Seal and Protect sealant, fluoride varnish, and erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser in reducing cervical dentin hypersensitivity (DH). Materials and Methods: Sixty patients each with at least one hypersensitive premolar were selected and randomly assigned to four groups: Gluma Desensitizer, Seal and Protect sealant, Duraphat fluoride varnish, and Er,Cr:YSGG laser. The assessment method used to quantify sensitivity was the cold air syringe, and the sensitivity was recorded by the visual analog scale (VAS), before treatment (baseline), immediately after treatment, and after 1, 2, 3, and 8 weeks. Results: The study results showed that there was a significant reduction in sensitivity at the various time intervals with all the four desensitizing agents – glutaraldehyde in methacrylate resin (Gluma Desensitizer), nanofilled methacrylate resin (Seal and Protect), sodium fluoride varnish (Duraphat), and Er,Cr:YSGG laser therapy. Conclusion: It can be concluded that after 8 weeks of clinical evaluation, all therapies showed lower VAS sensitivity values compared with baseline, independently of their different modes of action. The study indicates that Er,Cr:YSGG laser can emerge as an efficient treatment alternative in the reduction of DH.","PeriodicalId":345720,"journal":{"name":"Journal of Dental Lasers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132279793","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}
