Aim: To determine the enamel solubility and depth of demineralization with laser bleaching and impact of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) when applied prior to and after laser bleaching. Materials and methods: The 40 specimens obtained from 10 human premolars were treated in accordance with manufacturer protocols; laser bleaching was performed using Opalescence Boost Gel (40% hydrogen peroxide) followed by laser activation using 36 mW/660 nm diode laser applied for 4 minutes at an energy fluence of 8.6 J/cm2. The study consisted of four experimental groups are as follows: • Group 1: Control (laser bleaching only) • Group 2: Pretreatment with CPP-ACP and laser bleaching • Group 3: Laser bleaching and post-treatment CPP-ACP • Group 4: Laser bleaching and post-treatment CPP-ACP and short burst of laser. Specimens were, thereafter, subjected to cariogenic challenge and further evaluated for enamel solubility by measuring the loss of Ca2+ ions and the depth of demineralization using polarized light microscopy. Results: Group 4 exhibited least enamel solubility and depth of demineralization (p < 0.0001) followed by groups 3, 2 and maximum by group 1. Conclusion: Post-laser bleaching application of CPP-ACP followed by a short burst of laser can provide exceptional resistance to enamel solubility (demineralization).

Dental lasers are becoming an integral part of contemporary dentistry. Lasers can artistically sculpt soft tissues while providing precision, increased visibility, improved impression techniques; predictable healing with decreased scarring, reduced anesthesia and postoperative swelling. With the introduction of the hard-tissue laser, cosmetic bonding procedures are more predictable by providing enhanced bond strength, more comfortable by requiring little to no anesthesia, and less invasive via controlled removal of tooth structure. To protect the faith of patients on the clinician, we must be familiar with the fundamentals of laser physics and tissue interaction so that the proper laser device is used to obtain the treatment objective safely and effectively. This review will discuss about laser physics in detail to make its use more scientific and reliable for both clinicians and patients.

Minimally Invasive Management of Pericoronal Abscess using 810 nm GaAIAs Diode Laser

[Year:2014] [Month:] [Volume:4] [Number:3] [Pages:4] [Pages No:79 - 82]

Acute exacerbations of pericoronitis is associated with debilitating symptoms, and requires urgent intervention. Mechanical debridement, operculectomy and antibiotic therapy are parts of established treatment protocol, however, associated with many limitations. This report highlights successful management of a case of pericoronal abscess around mandibular third molar in a 30-year-old female, with GaAlAs diode laser-assisted disinfection and operculectomy. Although infection was initially associated with lymphadenitis and fever, postoperaive period was symptom free, even without use of antibiotics. Due to many intraoperative and postoperative advantages and better patient acceptance, diode laser has become a preferred option for minor oral surgical procedures.

Effectiveness of 980 nm Diode Laser Therapy on Recurrent Aphthous Stomatitis

[Year:2014] [Month:] [Volume:4] [Number:3] [Pages:4] [Pages No:83 - 86]

Recurrent aphthous stomatitis (RAS) is the most common oral ulcerative lesion, often associated with stress, insomnia, trauma, etc. There are many different treatment modalities for but with partially effective treatment outcome. Therefore, the aim of this report is to review the low-level laser therapy (LLLT) for effectively relieving pain and its ability to aid in faster healing of ulcers. A 21-year-old male reported with intense pain due to RAS, was managed with LLLT with laser settings at 1 W power in continuous and noncontact mode. Immediately after the irradiation, patient was absolutely free from pain after 3 and 7 days of evaluation, there was absolutely no pain with partial healing and complete re-epithelization of ulcer respectively. It can be concluded that lasers at nonablative settings in the form of LLLT provides immediate relief from pain and discomfort and aids in the rapid healing of ulcer.

Diode Laser-assisted Lingual Frenectomy: A Case Series

[Year:2014] [Month:] [Volume:4] [Number:3] [Pages:4] [Pages No:87 - 90]

A short or thick and fibrotic lingual frenum results in ankyloglossia or tongue-tie. Restricted tongue movement in ankyloglossia may at times result in speech problem with difficulty in pronunciation of some sounds, impaired mechanical cleaning of the oral cavity by free tongue movement, gingival recession or malocclusion. Thus, the surgeries for ankyloglossia can be considered at any age depending upon patient's history of speech, mechanical and social difficulty and can be performed by scalpel, electrocautery or lasers nowadays. The paper presents report of three cases where diode laser has been used for lingual frenectomy. Diode laser has shown to be one of the excellent options for performing these surgeries with better bleeding control, excellent precision, less discomfort and short healing time.
