Anticariogenic Sanative Effect of Aluminum Gallium Arsenide Crystals on Hydroxyapatite Crystals

Dental caries is a progressive disease with varying phases of demineralization and remineralization, and the scope of reversing the carious lesion is increased if it is diagnosed before there is surface cavitation. Preventive management strategies are directed towards making the enamel more resistant towards acid dissolution. The caries preventive protocol has always been fluoride-centric. Repeated application of fluoride gives rise to acquired fluoride resistance strains of Streptococci mutans which can be transient or permanent. The need of the hour is an effective remineralizing protocol which is one which brings about a change in enamel crystal and makes it more resistant to the acidic challenges of the oral cavity. The authors have devised a protocol in which irradiation with aluminum gallium arsenide crystals LASER can bring about a sanative change in crystal and lead to greater acid resistance of the enamel crystal and thus potentiate the remineralization of non-cavitated lesions. The concept of aluminum gallium arsenide–assisted caries inhibition and the proposed hypothesis of the mechanism of action is discussed.
