(n.) A carnassial tooth; especially, the last premolar in many carnivores.
Example Sentences:
(1) Electromyographic activity from the balancing-side muscles is nearly equal to EMG activity of the working-side muscles during bone crushing with the carnassial teeth.
(2) Working-side muscle activity produced bone strain that correlated with a compressive joint loading, while balancing-side muscle activity, with an occlusal fulcrum at the carnassial teeth, produced bone strain indicative of an anteroventral movement of the working-side mandibular condyle which eventually ruptured the joint capsule.
(3) It is proposed that working-side muscle activity exceeds balancing-side muscle activity during carnassial biting to maintain jaw-joint stability.
(4) It is hypothesized that a high percentage of balancing-side muscle activity in ferrets can be recruited during carnassial biting because the postglenoid process prevents ventral displacement of the working-side mandibular condyle.
(5) Electromyographic activity was also recorded during biting while a bite-force transducer placed between the carnassial teeth registered forces ranging from 1.5 to 48.8 N. Linear regression analysis demonstrates that temporalis and masseter EMG activity are linearly related to bite force.
(6) Special emphasis will be placed on coronal access of the canine, carnassial and incisor dentition.
(7) When the temporalis and masseter muscles were stimulated bilaterally with a carnassial bite point, bone strain indicative of a ventrally directed and potentially damaging condylar movement was produced.
(8) The combined effect at the carnassials was a 36 per cent improvement in the efficiency of the lever for which the joint is the fulcrum and thus an equivalent reduction in the disarticulating force.
Premolar
Definition:
(a.) Situated in front of the molar teeth.
(n.) An anterior molar tooth which has replaced a deciduous molar. See Tooth.
Example Sentences:
(1) Maxillary and mandibular incisors and premolars of three rhesus monkeys were used.
(2) Erosion was observed on all teeth, but was commonest on the upper incisors, canines and premolars, and severest on palatal surfaces.
(3) Sound (n = 28) and carious (n = 123) approximal surfaces of extracted premolars and molars were radiographed.
(4) Four weeks after replantation, a more than threefold increase in PBF was measured in premolars with two roots, while PBF in premolars with one root and incisors was consistently reduced to an average of 40% of the controls.
(5) Molarization and premolarization of anterior teeth have never been reported before.
(6) The mandible does tend to rotate in a counterclockwise manner following enucleation of four first premolars without appliance therapy.
(7) Eight cases were studied separately, since three showed bilateral congenital absence of the second premolar, three showed unilateral congenital absence of the second premolar on the affected side, and two had the first permanent molar extracted.
(8) A "sweep" bend was incorporated to avoid unwanted side effects at the second premolar.
(9) Furthermore, agenesis of incisors, canines and premolars ranges from 0.4% in controls to 1.3% in propositi having reduced ULI and 5.0% in propositi with two missing ULI.
(10) The aberrant gland appeared on a panoramic radiograph as a radiolucency judged to be a periapical lesion on the right mandibular second premolar.
(11) All premolars were extracted after 1 calendar month.
(12) The purpose of the present radiologic study was to establish prevalence and distribution of pulp stones in mandibular premolars and molars in skulls of Norwegian Samis.
(13) One hundred and eighty seven mandibular premolars taken from a Turkish population were examined in this study.
(14) Forty molar and premolar teeth had non-retentive cavities prepared and restored with amalgam using (1) copal varnish (control), (2) a pin, (3) Amalgambond or (4) Panavia-Ex.
(15) Bone biopsies should be taken in either the premolar or the molar region of mandibular bodies.
(16) An unusual case of Stafne's bone cavity which presented in the canine-premolar region of the mandible is presented.
(17) Spaces needing prosthetic closure are transferred to more posterior regions of the dental arch, usually in the premolar region.
(18) In a second series of analyses, the mean lead concentrations of both dental hard tissues of premolars and permanent molars of young individuals from Strasbourg, rural Alsace, and Mexico City were compared.
(19) Autotransplantation of mandibular first premolars to the incisor region is suggested as an approach in selected cases.
(20) The samples were collected from both an intact fissure and a fissure with brown-stained defective enamel surface of the premolars of the lower jaw.
