Tooth Whitening, the Microabrasion Technique, and White Spot Eradication
Published in Linda Greenwall, Tooth Whitening Techniques, 2017
In a study undertaken by Muñoz et al. (2013) in which suitable teeth were infiltrated with resin, the researchers found that the most successful cases were the ones with fluorosis stains. These cases showed visibly perceptible differences. The hypoplasia areas were not completely eradicated. The researchers reported that the patients recovered their self-esteem as a result of the treatment and thus this was considered a success. The effect of the hydrochloric acid on the enamel was evaluated in a study by Paris et al. (2010). These researchers evaluated the etching effect of the hydrochloric acid versus phosphoric acid on deciduous teeth. They evaluated 36 pairs of primary molars with enamel lesions, then etched for 2 minutes with both phosphoric acid and hydrochloric acid. They examined the results using confocal microscopy. They reported that there was a difference between the two acids on the surface of the teeth and that the hydrochloric acid caused higher erosion on the enamel, thus allowing deeper penetration of the resin infiltrant. The erosion depth of the hydrochloric acid was twice the depth of the phosphoric acid. The phosphoric acid at an etching time of 2 minutes cannot erode the surface of the enamel. It seems that the resin infiltration technique can reduce long-term restorative needs and costs, thus complementing the concept of minimal-intervention dentistry (Kielbassa et al. 2009).

As glass ionomer cement (GIC) is the primary restorative material used in minimal intervention dentistry and atraumatic restorative treatment, its popularity in the treatment of cavitated lesions is growing among dentists (Frencken and Holmgren 2014; Frencken 2017). Due to its favourable features of fluoride release, chemical bonding to the tooth structure, good biocompatibility, and coefficient of thermal expansion similar to that of dentine, it has a high versatility of usage (Wiegand et al. 2007; Farrugia and Camilleri 2015; Sidhu and Nicholson 2016; Mishra et al. 2017). The biggest attributes of GICs are tooth remineralization and reduction of demineralization of the dental hard tissues by fluoride release, which makes it superior to other direct restorations (Wiegand et al. 2007; Roveri et al. 2009; Zhou et al. 2012). Fluoride also contributes to caries prevention by interfering with cariogenic bacteria, and disturbs bacterial colonization and biofilm formation, affecting bacterial metabolism and its acid production by the inhibition of the glycolytic enzyme enolase and proton-extruding ATPase (Hamilton 1990; Wiegand et al. 2007). Thus, the fluoride interacts with both the host (tooth) and resident oral microflora.

To be able to plan resource allocation for non-operative activities, there is a need to understand the present situation regarding oral health status among the elderly. Presenting detailed caries registrations for all severities of lesions gives the opportunity to discriminate between different treatment options: those lesions dentists suggest for operative treatment and those they suggest for non-operative caries treatment. Treatment principles outlined in the FDI (International Dental Federation) statement on Minimal Intervention Dentistry [15] aim to base treatment of caries and oral disease on the understanding of the caries process and disease control. [16]. Today, it is recognized that early lesions, i.e. caries grade 1–2, and in some cases grade 3, should be treated without operative measures, since there is strong evidence that such lesions can be arrested [17]. To be able to plan non-operative measures, treatment and recall intervals, it is important to register and grade initial caries lesions, as well as the more severe dentin lesions. To disclose the number of enamel lesions could motivate the clinicians to non-operative treatment, which is in accordance with new concepts of modern caries treatment [18].
