TL;DR: Practical aspects of salivary as research material with emphasis on protein biochemistry and physical chemistry are described, including its potential to diagnose viral, bacterial and systemic diseases.

TL;DR: MMP-8 represents the major collagenase in human dentin and dentinal gelatinases can be detected after autoclave treatment of dentin, indicating their high resistance to external sample treatment procedures.

TL;DR: The onset of RMMA and SB episodes during sleep are under the influences of brief and transient activity of the brainstem arousal-reticular ascending system contributing to the increase of activity in autonomic-cardiac and motor modulatory networks.

TL;DR: MSC from bone marrow differentiate towards osteogenic lineage, representing a suitable cell source for bone formation in periodontal regeneration, but its short degradation time may be a limitation for a future application in bone tissue regeneration.

TL;DR: DAPI-staining as well as FISH have proven success for visualization of initial intraoral colonization of enamel specimens and bacteria were detected in the initial in situ biofilm irrespective of the formation time.

TL;DR: Palatal rugae shape revealed significant differences between the two Indian populations and also confirmed previous reports of lack of sex dimorphism and it is inferred that discrete variables such as rugaeshape are better suited for the purpose than continuous variablessuch as rugAE length.

TL;DR: The variations in hardness and Young's modulus on cross-sectional samples of human molar enamel are attributed to changes in local chemistry (varying levels of mineralization, organic matter, and water content) and changes in microstructure ( varying volume fractions of inorganic crystals and organic matrix).

TL;DR: A cell line of immortalized human dental pulp cells with odontoblastic differentiation which will be a useful cell model for studying the mechanism of proliferation and differentiation of Odontoblasts is established.

TL;DR: It is shown that strain distribution differs in alveolar and mid-corpus segments of the mandible and that the latter develops an alternate pattern between the buccal and lingual aspects of the working and balancing sides of the jaw.

TL;DR: The data indicate that biofilm formation of C. albicans and non-albicans Candida species is modulated by hydrodynamic conditions and ambient oxygen gradients, however, further work is required to fully elucidate how Candida biofilms persist within the oral milieu under such challenging ecological pressures.

TL;DR: The intra-oral environment was considerably protective for CaF2-like precipitates especially on enamel and dentine, and more KOH-soluble fluoride was lost under erosive compared to neutral conditions.

TL;DR: Various findings suggest that the face MI is important in orofacial motor skill acquisition and adaptation to an altered occlusion or loss of teeth or lingual sensory function, and that it reflects dynamic and modifiable constructs that are modelled by behaviourally significant experiences and that are critical to learning and adaptive processes.

TL;DR: The results show that the observed effect of fluoride on enamel demineralization is not solely a function of bulk solution properties, but also depends on the caries-status of the enamel surface.

TL;DR: Evaluated behaviour of osteoblastic-induced human bone marrow cells regarding proliferation and functional activity, in the presence of representative therapeutic concentrations of doxycycline and minocycline showed a potential application in therapeutic approaches aiming to increase bone formation.

TL;DR: This paper presents unequivocal evidence for the presence of RNA in saliva as determined by the use of diverse techniques such as reverse transcriptase quantitative polymerase chain reaction (RT-qPCR), in vitro translation, and the construction of a salivary cDNA library.

TL;DR: Variations in salivary components were correlated with sensory perception of a number of flavour, mouth feel and after feel attributes in the semi-solids mayonnaise and custard dessert.

TL;DR: These findings suggest that a supplementation of chitosan to gum is an effective method for controlling the number of cariogenic bacteria in situations where it is difficult to brush one's teeth, such as when an individual is away from home all day or participating in outdoor training.

TL;DR: The data suggest that the competitive interactions of fungal species are likely to be important in biofilm formation on acrylic surfaces and human saliva may further modulate this process.

TL;DR: It is demonstrated that polymorphisms of high IL-1β and TNF-α production were associated with an increased risk of RAS development, giving additional support to a genetic basis for RAS pathogenesis.

TL;DR: Brushing load influences abrasion of briefly eroded enamel, but might be of minor importance for abRasion of sound enamel surfaces.

TL;DR: Data are consistent with the hypothesis previously proposed that the lateral pterygoid should be regarded as a system of fibres that acts as one muscle, with varying amounts of evenly graded activity throughout its entire range, and with the distribution of activity within the muscle being determined by the biomechanical demands of the task.

TL;DR: These findings suggest that, two 90-min exercise sessions performed at a moderate intensity with a 2.25h rest in between do not necessarily have adverse effects on salivary IgA levels.

TL;DR: The effects on the sensitivity of exposed dentine to cold that are produced when dentine is etched to remove the smear layer and when the tubules are blocked again with calcium oxalate were determined to determine if the pain was due to hydrodynamic receptors, their sensitivity to dentinal fluid flow changed when the tubes were opened or closed.

TL;DR: Results suggest that periosteal-derived cell has the potential osteogenic activity and could be a good candidate for tissue engineering to restore the bony defects of the maxillofacial region.

TL;DR: A distinct role of MEPE and DMP1 is suggested in the response of osteocytes to mechanical loading in vivo, suggesting a distinct role in mineralisation and demineralisation within the osteocyte microenvironment.

TL;DR: Masticatory muscles are anatomically and functionally complex in all mammals, but relative sizes, orientation of action lines, and fascial subdivisions vary greatly among different species in association with their particular patterns of occlusion and jaw movement.

TL;DR: According to a quantitative model of responses in periodontal receptors, most receptors efficiently encode food contact during chewing, but due to the marked saturation tendencies at higher forces these receptors poorly encode the magnitude of the strong chewing forces and the force changes occurring at these high loads.

TL;DR: DSP and PP could be suitable biological markers for monitoring root resorption during orthodontic treatment, since a significant difference in the level of these dentin specific proteins is detected in all groups.

TL;DR: Rinsing with an iron solution after an erosive attack, followed or not by an abrasive episode, may be a viable alternative to reduce the loss of dental structure.

TL;DR: Important developmental and nutritional variables at birth and throughout the early life may predict the numbers of emerged teeth children have in their oral cavity.
