“…In both the SE and SB groups, mixed fracture was mainly observed after the MTBS test (Table 1, Figures 3 and 4). The results of the fracture mode for the SE groups were in agreement with a previous study on sound dentin,38 but that for the SB group were in disagreement with the previous study 38. In the previous study, the shear bond strength of the SB group was significantly lower than that of the SE group, and adhesive fracture was mainly observed 38.…”

“…The results of this study were similar to those of previous studies in which no significant difference in bond strength between primary tooth dentin and permanent tooth dentin was found 36, 37. However, other studies including Clearfil SE Bond38 reported that bond strengths of primary tooth dentin were significantly higher than that of permanent tooth dentin 38, 39. There are indications of some differences between primary and permanent tooth dentin.…”

To measure the micro-tensile bond strength (MTBS) on sound and caries-affected primary tooth dentin using an original designed jig that was developed for making symmetric and uniformly-sized specimens for the micro-tensile strength testing. The MTBS of dumbbell-shaped specimens and matchstick-shaped specimens were measured. Dumbbell-shaped specimens: The occlusal surfaces of 15 sound primary molars were ground with a water-cooled air turbine using a diamond bur. The adhesive systems and resin-based composites were Clearfil SE Bond and Clearfil AP-X (SE group) and Single Bond and Z250 (SB group). Matchstick-shaped specimens: Sixteen primary molars (5 sound and 11 carious) were used. The occlusal surfaces of sound teeth were ground with a water-cooled air turbine using a diamond bur. Infected dentin was determined by a caries detecting dye solution and removed with a round-shaped steel bur under water-cooling and with a hand instrument. SE was applied. Data was statistically analyzed using ANOVA and Fisher's PLSD at p < 0.05. The MTBSs (MPa) for the dumbbell-shaped specimens were 8.9 +/- 7.0 in the SE group and 10.3 +/- 5.8 in the SB group and that for the matchstick-shaped specimens were 9.0 +/- 6.3 in the sound-SE group and 9.2 +/- 5.8 in the carious-SE group. No significant difference was observed among them.

“…It is also claimed that the patient feels less pain with this technique, making it more acceptable to patients, especially children [Lozano-Chourio et al, 2006]. There are many studies on cavities treated with this technique [Banerjee et al, 2000a;Fluckiger et al, 2005;Hosoya et al, 2005] but its effectiveness on removing the infected dentine only and leaving the partially demineralised affected dentine to recalcify is still doubtful. Combining XMT and bacterial stains, repeated scans can be taken on each stage of progressive caries removal using various techniques to identify the affected layer and measure its mineral concentration.…”

An X-Ray Microtomography Study on the Mineral Concentration of Carious Dentine Removed during Cavity Preparation in Deciduous Molars

Dentists use a number of criteria in order to assess when a cavity is caries free, amongst which hardness is probably the most widely used. However, the judgement is subjective. X-ray microtomography (XMT) is a non-destructive microscopic technique that allows in vitro specimens to be scanned, manipulated and then rescanned. In this study, a high-definition XMT scanner was used to determine the mineral distribution of carious dentine in 10 deciduous molars, and the extent of dentine removed by an experienced clinician was investigated. For each tooth, after an initial XMT scan, caries was removed using a steel bur in a slow hand-piece. The tooth was then repositioned and rescanned. Mineral concentrations were calculated from the linear attenuation coefficients assuming the mineral phase to be hydroxyapatite and the organic phase to be collagen. The volume of dentine tissues removed was calculated by subtracting data of the second scan from the first. The results showed that the mean modal mineral concentration for the 10 teeth was 1.42 g · cm^–3 for sound dentine. Because of uncertainty about collagen concentration in carious dentine, the mean modal mineral concentration for the carious dentine had a range of 0.37–0.5 g · cm^–3. It was found that the subjective criteria used by the operator could lead to inconsistency of cavity preparation. The cavities could be overprepared by 8.5–44.3% in volume. However, the overpreparation was not uniform throughout the cavity: residual demineralised dentine could still be detected in the postoperative scan in isolated regions.
