    Notes: A newly developed fluoride-releasing composite and sealant were tested, in vitro, with regard to homogeneity, cavity adaptation, microleakage, and its effect on the extent of an artificially induced carious attack. Compared with a commercially available composite, the fluoride-releasing material showed more desirable properties in combating caries, in uniformity of internal structure, and in microleakage.

    Isometric endurance of masseter muscle in children (1981)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Eight children, mean age of 12 years, exercised maximal voluntary tooth clenching to determine the isometric endurance time of the masseter muscle. The endurance time seemed to depend on psychological and/or physiological determinants. The latter might have been Wedensky inhibition, changes in energy metabolism, progressive fatigue and so-called muscle fitness.

    Some subjective-experiential parameters of experimental tooth clenching in children (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Medicine
    Notes: Twelve children, aged 9–14 years, exercised maximal voluntary tooth clenching until facial pains were experienced and could no longer be endured. The pains were localized in the masseter and temporalis muscles and, occasionally, in the supra-orbital region. After onset of clenching pains appeared, on average, in 49 s (pain threshold) and they could, on average, be endured for 118 s (pain tolerance). The pain threshold varied significantly between individuals, but not within individuals. The number of pain sites, and the number of teeth in contact during clenching, did not determine the moment of onset of pains, nor the ability to endure pains. The pain tolerance did not seem to be influenced by the pain threshold.

    Some electromyographic parameters of experimental tooth clenching in adult human subjects (1980)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Medicine
    Notes: Eight adult human subjects exercised maximal voluntary tooth clenching until fatigue and pains were experienced, and could no longer be endured, in the right masseter muscle. The integrated electrical activity in the right masseter muscle was determined as a ratio of the different isometric exercises, and it showed a consistent decrease from onset of fatigue, via onset of pains, to the endurance of pains, possibly because of progressive muscle fatigue. The relative muscle activity might have determined the perception of the moment of onset of fatigue in the masseter muscle, and the perception of the moment of muscle exhaustion, but not the perception of the moment of onset of muscle pains.

    Effects of experimental loss of teeth on the temporomandibular joint (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 13 (1986), S. 0 
    Details
    ISSN: 1365-2842

    Topics: Medicine
    Notes: A review is presented of the effects of loss of teeth, with impaired occlusal stabilization, on the temporomandibular joint in experimental animals. Loss of teeth, with subsequent abnormal loading of the temporomandibular joint, leads to histomorphological, pathological and pathophysiological changes in the articular cartilages, the articular disc, the synovium, and the bony articular components. The severity of the changes increases with increasing age, and an existing arthritis of the joint is aggravated by impaired occlusal stabilization. The experimentally induced changes resemble those in human subjects with extensive loss or extensive attrition of teeth.

    Physiology and pathophysiology of skeletal muscle contractions (1986)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 13 (1986), S. 0

    Notes: An overview is presented of the physiology and pathophysiology of dynamic skeletal muscle contractions in the intact living organism. Dynamic muscle activities are divided into concentric contractions with shortening of muscle fibres and the production of positive work, and eccentric contractions with lengthening of muscle fibres and the production of negative work. In positive work, muscle tension overcomes external forces. In negative work, external forces overcome muscle tension. The latter phenomenon, with relatively few active motor units, explains the injuries induced by eccentric contractions. Both the contractile and non-contractile elements are involved in the muscle injuries and, clinically, they are referred to as myofibrositis.

    Notes: An overview is presented of the physiology and so-called pathophysiology of static muscle contractions in the intact living organism. Static muscle activity produces no external mechanophysical work, but is used for fixation. Contingent upon the levels of the generated forces, and the duration of the isometric contractions, static activities give rise to fatigue and pains. The discomforts are viewed as somatic responses that are normally within physiological limits. That is, upon cessation of isometric contractions there is usually rapid recovery from the discomforts, and they do not normally induce chronic lesions.

    Lateral preference in mastication: an electromyographic study (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 12 (1985), S. 0 
    Details
    ISSN: 1365-2842
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: To study concurrence of specific electromyographic chewing patterns and the side of mastication, twelve subjects chewed gum for 15, 20 and 25 s. Gum bolus placement on the right or left side of the dentition was estimated by three series of visual inspections. Contraction patterns of the chewing and non-chewing side masseter muscles were appraised by integrated and cumulative surface electromy-ography. Consistent and predominant gum bolus placement on the right side of the dentition could be predicted fairly reliably from comparative electromyographic observations. This was also the case in instances of consistent left-sided gum bolus placement, but not in predominant left-sided bolus placement. The latter phenomenon was explained by deviant observations made in two subjects only. Agreement between a presumed chewing side and a predictive contractility pattern was established in 78% of observations (P〉0-001).

    Contractile activity of the masseter muscle in experimental clenching and grinding of the teeth in man (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 11 (1984), S. 0

    Topics: Medicine
    Notes: Six human subjects exercised maximum voluntary tooth clenching and right-sided tooth grinding to determine the onset of fatigue in the right and left masseter muscle. Static and dynamic contractile activity of the two muscles was determined by surface electromyography. Muscle fatigue appeared after about 30s of isometric contractions (clenching), while 30s of combined concentric and eccentric contractions (grinding) induced no fatigue. In the right muscle the contractile activity of negative work (eccentric contractions of mandibular laterotrusion) was about 50% of that of positive work (concentric contractions of mandibular mediotrusion). During clenching an increased number of contacting teeth might have facilitated the contractile activity of the two muscles. During grinding the height of the cusps of the working side teeth might have contributed to a decrease of tension production by the right masseter muscle. Non-working side tooth contacts and peripheral receptors might have facilitated the contractile activity of the left masseter muscle during tooth grinding. Static contractile activity of the mandibular elevator muscles produced high levels of isometric tension and led to masseter muscle fatigue in about 30s. The same duration of dynamic contractile activity, resulting in low levels of tension during positive and negative work, did not induce fatigue.
