“…The heat energy produced from laser application is utilized to remove stains with ease. A recent study by Schoenly et al [ 94 ] tested the feasibility of using a near-UV laser (60-ns pulse rate) to remove internalized extrinsic stains on enamel. The laser was able to remove the stains, leaving a smooth enamel surface.…”

Light amplification by stimulated emission of radiation (laser) has been used widely in a range of biomedical and dental applications in recent years. In the field of restorative dentistry, various kinds of lasers have been developed for diagnostic (e.g. caries detection) and operative applications (e.g. tooth ablation, cavity preparation, restorations, bleaching). The main benefits for laser applications are patient comfort, pain relief and better results for specific applications. Major concerns for using dental lasers frequently are high cost, need for specialized training and sensitivity of the technique, thereby compromising its usefulness particularly in developing countries. The main aim of this paper is to evaluate and summarize the applications of lasers in restorative dentistry, including a comparison of the applications of lasers for major restorative dental procedures and conventional clinical approaches. A remarkable increase in the use of lasers for dental application is expected in the near future.

“…This is due to the wide range of applications of this radiation in different fields. In medicine it is used in UV laser surgery [1], in therapy [2], in dermatology, such as pigmented legion and hair removal, skin rejuvenation, and scalp psoriasis [3], in dentistry, such as near-UV laser treatment of extrinsic dental enamel stains [4], in optoelectronics applications [5], such as data storage [6] and telecommunications [7], in earth science [8], and in others.…”

Low cost ultraviolet stimulated emission has been generated using optical excitation of ZnO thin films deposited by sol-gel spin coating on n+As-doped100Si-substrate. The number of deposited layers and the heat treatment have been investigated to obtain a film that can generate stimulated emission under optical excitation. The optimum condition for preparation of the film has been presented. X-ray diffraction and scanning electron microscope have been used for structural and morphological investigations. Input-output intensity dependence and spectral width, peak emission wavelength, and the quantum efficiency versus the pump intensity have been presented. A quantum efficiency of about 24.2% has been reported, a power exponent higher than 8 has been obtained in input-output intensity dependence, and a threshold of about 23 Mw/cm2has been evaluated for the samples. The mechanism by which stimulated emission occurs has been discussed. The results show that sol-gel spin coating is a promising method for generating ultraviolet stimulated emission from ZnO thin films.

“…Enamel stains can be classified as intrinsic or extrinsic dark discolorations of the enamel 4. Intrinsic stains are located within the tooth structure and occur during tooth development as a result of metabolic disorder or systemic factors, such as porphyria and tetracycline administration 4.…”

“…Intrinsic stains are located within the tooth structure and occur during tooth development as a result of metabolic disorder or systemic factors, such as porphyria and tetracycline administration 4. Extrinsic enamel stains are superficial tooth discolorations adsorbed within the acquired pellicle or dental plaque and may also be retained on the tooth surface via ion exchange 4. Black-pigmented bacteria (BPB) are the cause of extrinsic black stains 3…”

Removal of black stains from teeth by photodynamic therapy: clinical and microbiological analysis

et al. 2015

Black-pigmented bacteria (BPB) are Gram-negative anaerobic, non-motile, proteolytic rods strongly implicated in the pathogenesis of periodontal disease. Although pigments are produced in vitro, black pigmentation is rarely found clinically. However, it may compromise aesthetics and contribute to gingival inflammation. The aim of this report is to describe a clinical case of a 10-year-old boy showing black pigmentation covering all teeth and to propose an alternative therapy for removal of black pigmentation, based on photodynamic therapy (PDT). In order to perform microbiological analysis, plaque samples were collected before and after PDT, and analysed by real-time-PCR (RT-PCR). The results showed a significant reduction in BPB levels after therapy, along with clinical evidence of absence of black pigmentation and reduction in gingival bleeding, although the plaque index remained unaltered. This case showed that PDT is effective for eliminating black pigmentation caused by BPB, without recurrence during a follow-up period of 7 months.

Near‐UV laser treatment of extrinsic dental enamel stains

Abstract: Laser ablation of extrinsic enamel stains at 400 nm is observed to be most efficient above 3 J/cm(2) with minimal damage to the underlying enamel. Unsound underlying enamel is also observed to be selectively removed after irradiation.
