DOI:10.4103/0976-2868.118444  
Context: Use of lasers in painless contemporary restorative dentistry. Aims: To assess the extent of painless perception using lasers for tooth preparation based on visual analogue scale (VAS). To compare conventional and laser tooth preparation using VAS scale. Settings and Design: Adult patients reporting to the Department of Conservative Dentistry were selected. Fotona fidelis make for ER:YAG laser was used at preset laser settings for enamel and dentin removal with combination of air-water spray. Materials and Methods: Standardized class I tooth preparation for composite restorations were selected for individuals requiring treatment for teeth with similar enamel/dentinal configuration, that is, contralateral in the same individual. Carbide burs-SS White #245 were used for all preparations. Identical tooth preparations were carried out by the same operator for both the teeth using conventional high speed on one side and ER:YAG laser at noncontact mode on the other side. Fotona fidelis make was used at preset laser settings for enamel and dentin removal with combination of air-water spray. The patient was required to provide score according to the VAS scale. Statistical Analysis Used: Kruskal-Wallis test. Results: The median of pain while preparing tooth by conventional method is the highest in patient (8) and the smallest in ER:YAG laser (1). The P value is very small (less than the common alpha-level of 0.05), the test is significant. Thus, it is concluded that the method of tooth preparation does affect the pain perception. Conclusions: The statistical analysis of these findings comprehensively prove that laser tooth preparation is much more painless, hence comfortable for the patient, only the economics prove to be a deterrent in its widespread usage.

Traumatic or irritation fibroma is a common benign exophytic oral lesion that develops secondary to tissue injury. It is the most common benign reactive lesion, and the treatment of choice is surgical excision. The use of lasers in different dental procedures has become very common. The diode laser which was introduced in dentistry since 1999. It is a solid-state semiconductor laser that typically uses a combination of gallium (Ga), arsenide (Ar), and other elements such as aluminium (Al) and indium (In). It has a wavelength ranging from 810 to 980 nm. This energy is absorbed by pigments in the soft tissues and makes the diode laser an excellent hemostatic agent and helps in ablation of soft tissue. Lasers have obvious benefits for all the patients without administering anesthetic shots and that means less time spent in the dental chair. Procedures were performed more conservatively, with less trauma for patients. Laser applications also enable the patient to enjoy a more relaxed dental experience, reducing or diminishing their fears, and resulting excellent post-operation experience for patients. This case series describes the use of diode laser on the excision of fibromas. The excision of fibroma using the diode laser was a quick clinical procedure without bleeding. During the days following surgery, the patient reported no pain or discomfort. The wound healing of the soft tissue was satisfactory and no scarring could be seen in the region of the surgery. The excision of the fibroma with the diode laser is a safe, quick procedure, with minimum postoperative discomfort and complications.

Pyogenic granuloma (PG) is a tumor-like growth in the oral cavity. It is manifested as a painless sessile or pedunculated, erythematous, exophytic and specific papular or nodular with a smooth or lobulated surface, which may have a fibrinous covering. The lesion usually bleeds easily on a slight provocation. PG is considered to be a non-neoplastic in nature. It is a reactive lesion, also classified in pregnancy associated gingival diseases. It occurs due to irritation or physical trauma from calculus or cervical restorations as also some contribution by hormonal factors and usually affects the gingiva, but can be seen in areas of frequent trauma such as lower lip, tongue, oral mucosa, and palate. The growth is typically seen on or after the third month of pregnancy and may grow rapidly to acquire a large size, thus, requiring surgical removal. The diode laser has also been used as an alternative treatment modality. This is a case report of PG in a patient treated with the diode laser.

Aim: A comparative evaluation of the gingival depigmentation by using a surgical blade and a diode laser; 6 months follow-up. Materials and Methods: Four systemically healthy patients who were aged 21-28 years were selected for the study and were treated with different gingival depigmentation techniques. Diode laser and surgical blade was used for the depigmentation in either of the arches. Pain levels were assessed using a visual analog scale (VAS) during the surgery, 1 day, 3 days and 1 week postoperatively. The recurrence of pigmentation was assessed with melanin pigmentation index (MPI). Results: The gingiva appeared pink and healthy after both the procedures and there was no recurrence of pigmentation. The clinical results obtained with the diode laser were esthetically pleasing with great patient comfort and satisfaction compared to the surgical blade. There was a statistically significant difference between the levels of pain during the procedure and 3 rd postoperative day between the two groups. Conversely there was no difference in the levels of pain 24 hours postoperatively and 1 week postoperatively among the two groups. Conclusion: The laser approach resulted in not as much of bleeding and pain as with scalpel technique. Although no difference in effectiveness and esthetic outcome were found between the two approaches, further well-conducted randomized trials would assist to make the absolute conclusion.

Melanin, carotene, and hemoglobin are the most common natural pigments contributing to the natural color of the gums. Although physiologic and ethnic melanin pigmentation is not a medical problem, complaints about "black gums" are common. Gingival depigmentation has been carried out using surgical, chemical, electrosurgical and cryosurgical procedures. Recently, "laser ablation" has been recognized as one of the most effective, pleasant and reliable techniques. Effective depigmentation of the gingiva requires removal of all or most of the melanocytes from the basal layer of gingival epithelium. In present case report the efficacy of gingival depigmentation using neodymium:yttrium-aluminium-garnet (Nd:YAG) and erbium:YAG (Er:YAG) lasers in same patient was evaluated.

Background: Application of laser energy onto exposed dentinal tubules provides instantaneous relief from dentin hypersensitivity. The aim of the present study was to compare between CO 2 and Nd:YAG laser irradiation for their sealing ability on human dentinal tubules when treated with and without fluoride varnish, using Scanning Electron Microscopy. Materials and Methods: Twenty extracted human intact third molar teeth were selected. A total of six samples were obtained from each tooth. One hundred and twenty dentin samples from 20 teeth were then divided into six groups with 20 samples in each group. These slabs were treated with 17% ethylenediaminetetraacetic acid (EDTA) for 5 min and with 5% NaOCl for the next 2 min for removal of the smear layer. Each of the samples from a single tooth was then subjected to six different treatment protocols according to the groups given below. Group 1 (n = 20) : CO 2 laser Group 2 (n = 20) : Nd:YAG laser Group 3 (n = 20) : Varnished with fluoride and lased with CO 2 laser Group 4 (n = 20) : Varnished with fluoride and lased with Nd:YAG laser Group 5 (n = 20) : Varnished with fluoride Group 6 (n = 20) (control) : Not subjected to lasing and fluoride application All samples were examined under scanning electron microscope. Results were subjected to statistical analysis using one-way analysis of variance (ANOVA) and the multiple comparisons among groups were carried out by Student's t-test. Results: Compared to conventional fluoridation or laser irradiation, in the treatment of dentin hypersensitivity, CO 2 lasers in combination with fluoride varnish appear to show better efficacy than either treatment modality alone.

July-December 2013, 7(2):59-65
DOI:10.4103/0976-2868.124266  
Objective: To evaluate the effect of low power diode laser (LPDL) 810 nm as an adjunct to nonsurgical treatment of mild to moderate aggressive periodontitis (AgP). Background: AgP is a rapidly progressive severe form of periodontitis; conventional treatment depends on the concept of plaque control and bacterial eradication. Scaling and root planning (SRP) is the basic periodontal treatment, has its limitations, so new treatment modalities are needed. Materials and Methods: The use of low power laser was suggested as an adjunct to periodontal treatment, as it was proven earlier to have a positive biomodulatory effect on biological tissues if suitable parameters were used for the condition in hand. A split-mouth design clinical trial was performed. The laser group received both SRP plus laser, and the control group only received SRP. The clinical evaluation included periodontal pocket depth (PPD), clinical attachment loss (CAL), plaque index (PI), modified gingival index (MGI), and gingival recession (GR), were taken at baseline and at 3 months. Transforming growth factor beta 1 (TGF-β1) was screened by sampling gingival crevicular fluid (GCF) at baseline and at 1, 2, 3, and 4 weeks after treatment. Results: Showed a significant decrease of PPD and CAL in favor of laser group. PI, MGI, and GR showed no significant difference between both groups. TGF-β1 mean percentage showed a significant steady decrease in the laser group. Conclusion: Low power laser parameters in this clinical trial can be used as an adjunct to SRP in treatment of mild to moderate AgP.

Muruppel Alex Mathews, Rajeev Milen Mariam, S Sudeep, N Dinesh
July-December 2013, 7(2):54-58
DOI:10.4103/0976-2868.124265  
Aims and Objectives: The purpose of this study was to objectively evaluate and compare the clinical efficacy of an in-office bleaching system using a titanium dioxide impregnated bleaching gel in conjunction with an 810 nm diode laser as opposed to a conventional in-office bleaching system. Settings and Design: The study was conducted in the Department of Prosthodontics, PMS College of Dental Science and Research, Vattapara. The study is an observational study of experimental design. Materials and Methods: Ten subjects were screened based on the inclusion and exclusion criteria. Resin dam was applied onto the gums and the teeth are isolated. Opalescence boost bleach gel is applied onto two quadrants of each patient, one with titanium dioxide and exposed to 810 nm GaAlAs diode laser and the other quadrant with conventional in-office bleaching using the same agent in trays. Comparison and assessment of degree of whitening between quadrants (and thereby techniques) was done using a Vita Shade guide. The dentinal hypersensitivity was assessed by means of air stimulus. Statistical Analysis Used: Non-parametric test (Wilcoxon signed test), was used to compare the effect of laser bleaching and conventional in-office bleaching based on visual analog score (VAS) score. To compare the shade difference McNemar test was used. Results: Statistically significant value, Z = 2.831 was obtained which proved that laser bleaching had significantly less sensitivity compared to conventional in office bleaching. McNemar test obtained a P value 1, showed that there is absolutely no difference in the brightness obtained by both laser bleaching and conventional in-office bleaching. Conclusions: Laser energy is able to effect physicochemical changes in enamel this is affected by crystalline changes within hydroxyapatite crystal and by the removal of the organic content or carbonate in the intercrystalline areas. Such changes also protect against the harmful effects due to extensive penetration of hydroxyapatite. Diode laser 810 nm has been shown to have effected such changes in bleaching settings.

July-December 2015, 9(2):94-99
DOI:10.4103/0976-2868.170565  
Background: An Aberrant frenum encroaches the gingival health when it is attached too closely to the gingival margin, either due to interference in the plaque control or due to a muscle pull. Such condition has to be treated by frenectomy which can be performed by scalpel, electrocautery, or with soft tissue lasers. Hence, the aim of the study is to compare the degree of postoperative pain and healing experienced by patients during frenectomy procedure with surgical scalpel and diode laser technique. Materials and Methods: A total of 20 subjects ranging from 16 to 40 years of age group with papillary or papillary penetrating frenal attachment in the maxillary anterior region were selected. Enrolled subjects were randomly divided into two groups as follows Group A (n = 10): Comprised of 10 subjects selected for conventional scalpel technique. Group B (n = 10): Comprised of 10 subjects selected for diode laser technique. Various parameters such as pain, inflammation, swelling, difficulty of procedure, and wound healing were evaluated at intervals of 1 week, 1 month, and 3rd month. Results: The results indicated patients treated with the diode laser had less postoperative pain (P < 0.0001) and required fewer analgesics (P < 0.001) as compared to patients treated with the conventional scalpel technique. Wound healing at 7th day and after 1 month for both the groups showed statistical significant difference with better outcome in Group A. However, wound healing at the end of 3 months did not show any significant difference between the groups. Conclusion: Based on current findings and clinical outcome, diode lasers provide better patient perception and an efficient and satisfactory option for procedures such as frenectomy.

DOI:10.4103/0976-2868.106668  
Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they are hurt, bleed, or are infected, they may require surgical treatment to expose the tooth and drain the contents. Here we present a clinical case of a 12-year-old child with an eruption cyst in mandibular right second molar treated using diode laser. No hemorrhage, swelling, infection or postoperative pain was observed. Treatment of eruption cysts with this technique facilitates obtaining a cooperative behavior from pediatric patients and makes behavior management easier.

Frenectomy is a common soft tissue procedure in the field of aesthetic dentistry. It prerequisites for many corrective and aesthetic treatments. Lasers have proved as a Midas touch for soft tissue procedures. Use of lasers is advantageous as there is no bleeding and pain during the procedure. Patients are comfortable during and post treatment. Here is a case of 36-year-old male with high labial frenal attachment between maxillary incisors who needed frenectomy followed by diastema closure.

Introduction:Irradiation of human dental enamel with laser energy at particular wavelengths in the visible and infrared regions result in greater resistance to acid and cariogenic attacks. The aim of the present study was to investigate the effectiveness of four commonly available laser wavelengths,KTP, Nd: YAG, Diode, CO2 in terms of the LAF protective effect to an erosive challenge. Materials and Methods: 40 sound human premolar teeth were used. The lingual and buccal surfaces of the teeth were sectioned into slabs using a diamond saw. The baseline Vicker's hardness number (VHN) of each surface was determined. 1.23% NaF gel was then applied to these slabs and they were divided into Group I - Control group. Group II - KTP Group III - Nd:YAG Group IV - Diode Group V - CO2. The Vicker's hardness number (VHN) of each surface was again determined after the fluoride and laser treatment. Results: Group II and Group III, which are KTP and Nd:YAG respectively showed significantly small amount of change as compared to the other groups. Conclusion: In order of merit least reduction in hardness after acid challenge was shown by Nd:YAG followed by KTP, CO2 and diode laser.
