“…On the other hand, the great similarity in microstructural and chemical composition of porcine and human dentin points to suitability of porcine dentin use in human dental research. Indeed, no significant difference is found between the bond strength of human and porcine dentin to a number of resin cements [43], and a similar outcome is reported after etching of either of dentin, porcine and human [44].…”

AbstractAnimal teeth are a common model in studies on dentin adhesive materials. The aim of this study was to compare microstructural parameters (density and diameter of dentinal tubules (DT), peritubular dentin (PTD) thickness, PTD and intertubular dentin (ITD) surface area) and chemical characteristics of canine, porcine, equine, and human root dentin. The middle layers of dentin were harvested just below a cemento-enamel junction from incisors and investigated by means of scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS). SEM evaluation of the specimens revealed, that porcine dentin shared most similarities with human dentin. When comparing the density of DTs, canine dentin was also found to be similar to human dentin. Elemental composition of the root dentin did not differ significantly in porcine, equine and human dentin, but in canine dentin higher magnesium value in PTD compared to ITD was found. It is known that microstructural and chemical characteristics affect the strength of the adhesive bonds created among restorative materials and dentin. According to the results of this study, porcine dentin seems to be the most appropriate model to study dental materials to be used in human restorative dentistry.

“…Swine teeth possess mineralization pattern of enamel comparable to that of humans [6]. It is considered that composition of swine enamel is similar to human enamel [2,20]. Experimental studies on skeletal system have also confirmed similarities between bone growth plate structure and mineralization process in humans and pigs [27].…”

“…Considering numerous anatomical and physiological similarities of the masticatory system such as heterodonty, difiodonty and bunodonty in humans and domestic pigs, one might easily conclude that results from studies of physiological factors influencing tooth development in pigs may be interpolated to humans. Swine teeth may be used as substitutes for human teeth in studies on adhesion and amelogenesis, because they are more similar to human teeth than the teeth of other mammals in relation to shape, size, morphology and period of development [17,20,24,26]. Swine teeth possess mineralization pattern of enamel comparable to that of humans [6].…”

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.

“…Common examples are primate (5), bovine (6), swine (7,8), equine (9), and shark teeth (10). However, bovine teeth have been the most widely used substitute for human teeth in dental studies and their use has dramatically increased in the last 30 years.…”

Bovine teeth as substitute for human teeth in dental research: a review of literature

2011

The aim of this paper was to review in vitro and in situ studies that directly compared the use of bovine teeth as a substitute for human teeth in dental experiments. A PubMed search was conducted for papers published from 1953 to December 30, 2010 using the following keywords: "human bovine enamel" or "human bovine dentin" or "human bovine teeth". The abstracts of the studies resulting from the keyword search were read, and all papers that compared human and bovine teeth were fully read. Only original articles written in English and directly comparing human and bovine substrates were included in the review. The search was supplemented by manual searches of the reference lists from each identified paper. Out of 76 studies initially selected, 68 fulfilled the selection criteria for inclusion. The studies covered seven categories: dental morphology, chemical composition, physical properties, dental caries, dental erosion/abrasion, bonding/adhesive strength, and marginal microleakage. Inconsistent data exist regarding whether bovine teeth can be considered an appropriate substitute for human teeth in dental research. Morphological, chemical composition and physical property differences between the two substrates must be considered when interpreting results obtained from any experiment using bovine tooth substrate.
