Gingival health and appearance are essential components for an attractive smile and removal of unsightly pigmented gingival is the need for a pleasant and confident smile. In some populations, gingival pigmentation seems to be a genetic trait and is irrespective of age and gender, hence gingival pigmentation is termed as physiologic or racial gingival pigmentation. Intraoral pigmentation is seen due to the presence of the fundamental pigment melanin that colors the tissues. Several treatment modalities have been suggested for gingival depigmentation. Many varying results have been observed, but the repigmentation has been documented to occur. The large variation in time of repigmentation may be related to the techniques used and the race of the patient. This case report demonstrates the probable cause of repigmentation where pigmentation has recurred limbs.

In vitro studies have already shown that superpulsed diode laser surgery has much less disadvantages for the tissues in histological approach. Purpose of this study was to investigate in vivo, if superpulsed mode of operation can realize an improvement for surgeon and patient in soft tissue surgery. A total of 26 patients were treated by diode lasers in different modes of operation for soft tissue surgery. Around 12 patients were treated by superpulsed Elexxion Claros diode laser: 810 nm; 10-50 W P peak ; 10-20 µs pulse duration; 12000-20000 Hz; 400 µm fiber. 14 patients were treated by Vision MDL-10 diode laser: 980 nm; 2.5 W; CW mode and also 400 µm fiber. Clinical treatment was documented by photos and questionnaires for patients and surgeons. Questions concerned: Carbonization, coagulation, cutting speed, pain, swelling, bleeding, need for drugs, functional reduction and fibrine layer on wounds-during treatment, directly after treatment, after 1 day, after 3 days and after 1 week. The clinical observations and the questionnaires showed in most cases signicant differences between CW mode and superpulsed diode laser treatment in surgery. It could be shown that superpulsed diode laser surgery is superior to continuous wave done treatment. Carbonization and thermal damage of the tissues can be reduced to a minimum, therefore healing is faster as in CW mode surgery. Generation of a soft tissue cut is faster and more precise. Patients have less pain in amount and time period. The need of drugs is reduced. There are less functional restrictions and there is less swelling. The advantages of superpulsed mode of operation for soft tissue diode laser surgery are evident. Continuous wave mode should no longer be implemented in diode laser surgery.

The wavelength of a diode laser is determined by the active compound used in the semiconductor. There are small but significant differences in the effects on tissue across these wavelengths due to the differing absorption properties of blood and the peak in the water absorption spectrum being at 975 nm. Diode lasers are fast becoming part of contemporary clinical practice and have since opened up vistas of unprecedented patient care. However, the nuances of their functioning and mechanisms of tissue interaction have not been widely discussed or clearly elucidated. This paper assimilates the facts in literature and throws light on the basics and essentials of this technological advancement that indeed has become a boon to all walks and branches of science.

Materials and methods The study was carried out on 30 subjects who fulfill the inclusion and exclusion criteria. Group I: 15 patients treated with SRP along with diode laser irradiation. Group II: 15 patients treated only with SRP. The clinical parameters were probing PD, RAL, BOP and PI which were recorded at base line, 7 days and after 1 month. Statistical analysis was done using Kolmogorov-Smirnov, Shapiro-Wilk, t-test, chi-square test. Results The use of diode lasers as an adjunct to SRP during maintenance phase showed better results when compared to SRP alone. Moderate periodontal pockets with moderate attachment loss showed significant improvement in group I than in group II. There was no change in deep pockets with severe attac...

Traditionally, it is an open-flap surgical procedure. Smile designing is becoming an increasingly popular treatment option, and the use of lasers for a crown lengthening greatly enhances the patient acceptability while reducing chairside time. There are no controlled studies for this application of lasers, however, a number of clinical case reports do exist. This article mainly focuses on reviewing all the current literature on crown lengthening performed by erbium lasers and exploring the process to achieve the best results.

Materials and methods: A total of 120 human single rooted extracted teeth were included in the study. The root canals were enlarged and laser irradiation was performed at four different settings (1 W continuous mode, 1 W gated mode 10/10, 2 W continuous mode and 2 W gated mode 10/10). The rise in temperature was measured at apical, middle and cervical thirds. The temperature changes were evaluated by a thermocouple. The threshold temperature rise of 7ºC is commonly considered as the highest temperature limit biologically acceptable to avoid periodontal damage. Results: The mean temperature rise on external root surface in our study was below 7ºC in all parameters and all portions of root surface. Conclusion: The 940 nm diode laser at 1 W CM, 1 W gated 10/10, 2 W CM and 2 W gated 10/10 can be considered safe for use for laser assisted root canal therapy.

With increase in numbers of implants, both newly placed and serving under function, it is necessary to achieve an understanding of the current evidence on diagnostic, prognostic and therapeutic aspects of peri-implant diseases. As therapeutic modalities are still evolving and consensus regarding their predictability yet to be achieved, a thorough risk assessment and early diagnosis assume added importance. This two parts review attempts to present the current state of evidence regarding the stated aspects of peri-implant diseases including peri-implant mucositis, peri-implantitis and their treatment modalities. The first part of the series presented in this paper addresses key issues regarding the case-definition, diagnostic, etiopatholgy and risk-related aspects while the second part will address the different treatment modalities with special emphasis on the use of laser radiation for peri-implant diseases.

Background: Administration of drugs for oral infections and pathologies are accompanied with a lot of limitations like lack of patient compliance, microbial resistance in the biofilm, systemic side effects, failure on the antibiotics to act on non-perfused areas, allergy and the limitation of spectrum of microorganisms affected. To overcome this, an effective and an alternative therapy needs to replace the conventional treatment. Indians since ancient past have been using the extracts of Psoralea corylifolia which contains furocoumarins, given orally, and followed by exposure to sunlight in order to treat vitiligo. Thus, PDT was investigated in the past as a promising alternative if not replacement for the conventional treatment. Clinical significance: It has been seen that various combinations of photosensitizer and lasers are effective against a broad spectrum of microorganisms. Porphyrin photosensitizers and temoporfin have been used successfully in the past against premalignant and malignant intraoral lesions. They are excellent options for palliative treatment for cases refractory to conventional therapy. Phenothiazinium photosensitizers like methylene blue and toluidine blue have shown to be effective against bacterias, viruses and fungal infections. Hence, they are effective tools for the treatment of refractory periodontics and endodontic infections. Conclusion: With the revolution of lasers in the field of dentistry and oncology, a new minimally invasive and precise approach towards the pathology is being developed. However, further research needs to be done in terms of development of newer formulations and dosimetry for more consistent results free of side effects.

In this literature review, various studies have been considered, some from outside of India as well as some from within India, which is the origin of our research. This was done to obtain a global view of the topic and also to be able to compare how Indian oral hygiene and awareness compares with the same for the rest of the world. In a study conducted in 2011 that pertained to the oral health practices was conducted in the rural areas of the Kanchipuram District in Tamil Nadu, India. The participants were children between the ages of 5 and 10. The mean age of the children was 8.5 years and there were a total of 81 participants. The aim of this survey was 'to evaluate the awareness and knowledge among the rural children on the dental health problems, their oral hygiene practices and the pattern of practices of dental treatment.' A number of results pertained to the oral health practices of the participants. A number of results pertained to the oral health practices of the participants were found in the study by authors VC Punita, P Sivaprakasam, in the rural children of Kanchipuram in the year 2011. 14 Out of the 81 children participating, only 51 children used toothbrushes while the rest used their fingers as a tool to clean their teeth. That accounts to only 62.96% brushing their teeth with brushes. This is attributed to the children coming from a 'very low socioeconomic background'. It was reported that 92.59% of the participants brushed their teeth once a day and 7.40% brushed twice a day. Moreover, only 45 out of the 81 children used toothpaste (55.55%) while the rest used twigs of the Azadirachta indica plant, traditionally known as datum, in combination with chalk powder, charcoal or sand. From the children who used brushes, 50.98% of them changed their brush when it got worn out, 27.44% of the participants changed their brush every 3 to 6 months. While the rest did not know how often they changed their brush. The author concludes that 'by giving adequate information, motivation and practice of the measure to the subject' this situation can be improved. In recent study done in 2012 authors Mehta A and Kaur G, it was found that 71.4% of the participants used a toothbrush with toothpaste, which is significantly higher than the 62.69% used by participants in the previously described study. 18 Moreover, in this study, only 1.4% of participants used the Azadirachta indica twigs to clean their teeth, which is a significantly better result than the previous study. In this study, 25% of participants brushed their teeth more than once a day, which is a major improvement over the 7.40%, reported in the previous experiment. In a study conducted by Amin and Al-Asad on the 'Oral hygiene practices, dental knowledge, dietary habits and their relation to caries among male primary school children in
