“…This fact explains significantly higher phosphorus content in the dentin of the equator of teeth with wedge-shaped defects compared with clinically intact ones. Obtained findings on the amount of magnesium and calcium in the dentin of the incisal region (tubercle), namely, a higher content of magnesium and a lower content of calcium at the level of 5% in the samples with wedge-shaped teeth agree with the results of the previous studies [17] in the teeth with occlusal wear facets that cause occlusal stress in the etiology of NCCL. A greater amount of magnesium in the dentin of teeth with wear facets can be a protective reaction to external influences [17].…”

A greater amount of magnesium in the dentin of teeth with wear facets can be a protective reaction to external influences [17]. Significant decrease in the amount of calcium in the incisal region (tubercle) and the cervical region in the dentin of teeth with wedge-shaped defects is explained by its role in the development of pathology of dental hard tissues [12,13].…”

The aim: Is to define dentine chemical composition of intact teeth and those with wedge-shaped defects followed by the analysis of revealed differences. Materials and methods: Longitudinal sections of 22 clinically removed teeth (12 – clinically intact ones, 10 – with wedge-shaped defects) from both jaws were studied in patients aged between 25-54 years. JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis INCA Penta FETх3 was used. The chemical composition of 148 dentine areas in the incisal region (tubercle), equator, cervical area has been determined as a percentage of the weight amounts of carbon, oxygen, calcium, phosphorus, sodium, magnesium, sulfur, chlorine, zinc, potassium, aluminum. Results: Dentine chemical composition of teeth with wedge-shaped defects differed from those of intact teeth by significantly lower content: sodium, chlorine and calcium – in the incisal region (tubercle); sodium, magnesium − at the equator; sodium, chlorine and calcium – in the cervical region (p≤0.05). In the sample groups with cervical pathology there was more sulfur and oxygen in the incisal region (tubercle), phosphorus and zinc – at the equator, carbon and potassium – in the cervical region (p≤0.05). Conclusions: Differences in the chemical composition of intact teeth and teeth with wedge-shaped defects, the presence of correlation between the studied chemical elements confirm the role of macro- and microelements in the pathogenesis of non-carious cervical lesions.

“…14 Compared with clinically intact teeth at the level of 5% smaller values of the coefficient of Ca/Mg in IR region and CA of dentin of the teeth with a wedge-shaped defect is probably due to tooth wear. 15 In all studied areas of the samples with cervical caries the molar coefficient of Ca/Mg was higher than in clinically intact ones that is explained by a higher concentration of magnesium in the hard tissues of healthy teeth according to the of data Klimuszko E. et al 16 According to Meisel P.et al (2016) the coefficient of Mg/Ca is serum that predicts periodontitis and tooth loss in a 5-year follow-up. 17 Higher values of Na/Mg and lower values of Al/Zn were determined in all investigated areas of dentin of the samples with cervical caries.…”

Objectives:Determination of molar coefficients of the chemical elements in dentin, their possible correlation with tooth enamel. Material and Methods:There were examined 29 clinically extracted teeth of both jaws and their longitudinal sections (12 clinically intact teeth, 10 teeth with wedge-shaped defects, 7 teeth with cervical caries) of the patients aged 25to 54 with the help of JSM-6490 LV focused beam electron microscope (scanning) with system of energy-dispersive X-ray microanalysis. We have determined the chemical composition of 290 enamel areas and 235 dentine areas in the incisal region (tubercle), equator, cervical area as a percentage of the weight amounts of carbon, oxygen, calcium, phosphorus, sodium, magnesium, sulfur, chlorine, zinc, potassium, aluminum, we have identified their molar coefficients. Results: The chemical composition of dentin differed in the values of Na/Mg, Al/Zn, Mg/Ca, K/Na (p≤0.05) in all studied topographical regions of the samples. Higher values of Na/Mg and lower values of Al/Zn were identified in the teeth with cervical caries (p≤0.05). Correlation was found in dentin: inverse between Ca/P and P/Ca, Mg/Ca and Na/Mg, Ca/Mg and Mg/Ca, Mg/P and Na/Mg, Mg/P and Ca/Mg, direct between Ca/Mg and Na/Mg, Mg/P and Mg/Ca (p≤0.05). High correlation was determined between molar coefficients in enamel and dentin: Mg/Ca and Mg/P (direct), Ca/P and P/Ca (inverse), p<0.0001. Conclusions:The differences in the indicators of molar coefficients in dentin, their correlation with enamel are probably associated with the peculiarities of the pathological processes in the cervical region and it requires further study.

The aim of this experimental in-vitro study was to investigate the machining of human dentin using an abrasive water jet and to evaluate the influence of different abrasives and water pressures on the removal rate. Seventy-two human teeth had been collected after extraction and randomly divided into six homogeneous groups (n = 12). The teeth were processed in the area of root dentin with an industrial water jet device. Different abrasives (saccharose, sorbitol, xylitol) and water pressures (15 or 25 MPa) were used in each group. Dimensions of dentin removal were analysed using a stripe projection microscope and both drilling depth as well as volume of abrasion were recorded. Morphological analyses of the dentin cavities were performed using scanning electron microscopy (SEM). Both drilling depth and volume of abrasion were significantly influenced by the abrasive and the water pressure. Depending on these parameters, the drilling depth averaged between 142 and 378 µm; the volume of abrasion averaged between 0.07 and 0.15 mm 3 . Microscopic images revealed that all cavities are spherical and with clearly defined margins. Slight differences between the abrasives were found with respect to the microroughness of the surface of the cavities. The results indicate that abrasive water jet machining is a promising technique for processing human dentin.
