“…14,15 Thus, it was hypothesized that caries detecting dyes prepared with higher molecular weight polypropylene glycols might prevent over-staining and excessive removal of caries-affected or sound dentin. In a previous study, 16 when dentin stained with Caries Check was completely removed, the DIAGNOdent readings were higher than those recorded when palely-stained pink dentin was retained with the Caries Detector, with significant difference observed for the permanent teeth. Thus, Caries Check may be used clinically to avoid excessive removal of caries-affected or sound dentin in permanent teeth but not in primary teeth.…”

“…Hosoya et al used dentin that was artificially softened at the cementoenamel junction, and ablated up to a hardness of 24.3 KHN, and they reported rehardening occurred following remineralization . 10 In this study, remineralization was expected to occur in the same area.…”

Objective: This study used artificially demineralized bovine dentin to ascertain the effect of hardness of demineralized dentin on ablation rate with the Er:YAG laser. Background Data: Before restoration of carious teeth, it is necessary to ablate any infected dentin that cannot be remineralized due to softening by the invading caries. A correlation has been suggested between the ablation efficiency of the Er:YAG laser and the progression of caries in dentin. To the best of our knowledge, no studies have investigated the relationship between degree of demineralization by dentinal caries and ablation rate with the Er:YAG laser. Materials and Methods: Bovine mandibular anterior tooth roots were used as dentin samples. Each sample was soaked in a demineralizing solution (2 M lactic acid, pH 4.0) for 3 d to obtain demineralized dentin (DD) samples. Another group of samples were prepared without demineralization as a sound dentin (SD) group for comparison. After determining the Knoop hardness number (KHN) of each sample, the dentin surface was ablated with an Er:YAG laser. Tip output and pulse rate were set at 50 mJ and 20 pulses per second (pps), respectively, and the water spray was set at 3.5 mL/min. Ablation width, depth, and volume were measured following irradiation. Results: In the DD group, dentin hardness was 10.4 Ϯ 1.6 KHN at 100 m from the surface. In the sound dentin group, Knoop hardness was 51.0 Ϯ 1.6 KHN cross-sectionally throughout. No differences were observed from the surface to a depth of 2000 m. In the DD group, dentin ablation volume at the superficial demineralized layer was 2888 Ϯ 272 ϫ 10 4 m. In the SD group, dentin ablation volume was 1298 Ϯ 219 m 3 . The relationship between ablation volume and Knoop hardness was defined as Yϭ -40.699x ϩ 3350, revealing a marked negative correlation. Conclusion:The results demonstrate that the ablation volume for demineralized dentin was greater than that for sound dentin. The results suggest that the Er:YAG laser is capable of ablating infected dentin without damaging sound dentin by adjustment of tip output and pulse rate. 395

“…The disadvantage of these dyes is that slight procedural variations can result in widely different degrees of dye uptake. They are mainly used for the detection and removal of carious dentine (45).…”

Accurate evaluation of demineralised white spot lesions during orthodontic treatment is important to both clinicians, so they might implement early prevention and/or treatment, and researchers who wish to study the effectiveness of those methods. Assessment will depend upon accurate detection and measurement of a lesion, using procedures that demonstrate good validity and reproducibility. A range of evaluative techniques are outlined and the advantages and disadvantages of each are discussed. Some methods can be applied by the busy clinician, whereas others are more suitable for the researcher undertaking a clinical trial. Regardless of who is using the technique, it should be relatively straightforward to apply in the clinical situation and whatever technique is undertaken, researchers and the clinicians must appreciate the need for proper research designs to produce reliable information regarding the effectiveness of any intervention.
