“…Apart from the TMD, DEXA allows the measurement of tooth mineral content (TMC), which is expressed in grams. The drawback of this method is the possible miscalculation of the measurement due to the presence of surrounding soft tissues, degenerative changes and osteophytic spurring [9,13,16,29,30]. The second used method in this study is quantitative computed tomography (QCT) that allows for separate measurement of volumetric bone mineral density of the trabecular and cortical bone compartments (expressed in g/cm 3 ) as well as determination of mean volumetric tooth mineral density (TvBMD) and total tooth volume (Tvol).…”

ABSTRACT. The aim of the study was to determine interrelationships between bone tissue metabolism indices and morphological, biomechanical and densitometric properties of hard dental tissues. First primary maxillary incisor from 6-month-old pigs (N=27) was evaluated in terms of weight and length. Mean volumetric tooth mineral density, total tooth volume, enamel total volume, enamel volumetric mineral density, dentine total volume and dentine volumetric mineral density were estimated with the use of quantitative computed tomography and micro computed tomography techniques. Tooth mineral density and tooth mineral content were evaluated with the use of dual-energy X-ray absorptiometry. Microhardness of enamel was measured using Vicker's test. Evaluations of total calcium, ionized calcium, magnesium, phosphorus, alkaline phosphatase, bone alkaline phosphatase, osteocalcin, C-terminal telopeptide of type-I collagen (CTX), insulin-like growth factor-1, growth hormone and parathyroid hormone were performed in plasma and serum samples. Pearson's correlation coefficients were determined between all the investigated variables, and P<0.05 was considered as statistically significant. The obtained results have shown mainly mutual dependences between biochemical indicators of bone metabolism. Evaluation of CTX concentration in serum of pigs has shown the highest predictive value in relation to morphological, densitometric and biomechanical properties of teeth. KEY WORDS: bone turnover marker, densitometry, quantitative computed tomography, swine, tooth.
