Solubility was increased by continually presenting fresh liquid, unsaturated with solute, to the cement-water interface. A liquid absorption test was developed to give an additional criterion for the life of dental cements.
Apparent Heats of Wetting and Heats of Reaction of the Components of Tooth Structure and Synthetic Fluorapatite
Authors: Huget Eugene F. , Brauer Gerhard M. , Loebenstein William V.
Published: November 2010

The apparent heats of wetting (ΔHW) and heats of reaction (ΔHR) of ground dentin, enamel, anorganic tooth, and synthetic fluorapatite of known specific surface were determined calorimetrically. Values of ΔHW in water were affected by the presence of collagenous matter. Reactions at the surface were caused mainly by organic groups, since the ΔHR values for anorganic tooth, enamel, and fluorapatite were much smaller when exposed to reagents.

Authors: Shaw James H.
Published: November 2010

Crossbred matings were made between two strains of caries-susceptible rats. Growth in crossbred populations was equal to or better than that in the rapidly growing purebred strain. Carious lesions in occlusal sulci were similar to lesions in the parent strains. The incidence of lesions on smooth surfaces was similar to the incidence in the less prone of the two parent strains.
Role of Attrition and Occlusal Contact in the Physiology of the Rat Incisor: II. Diurnal Rhythm in Eruption and Attrition
Authors: Michaeli Y. , Weinreb Max M.
Published: November 2010

Rates of eruption and of attrition were measured on impeded and unimpeded rat incisors at 6 AM and 6 PM. The rhythm of unimpeded eruption and attrition was diurnal. The rates increased during the night, as do rates of other physiologic processes in the nocturnal animal. When eruption was impeded however, this rhythm was reversed by the inhibiting force of occlusal contact.

Authors: Brauer G.M. , Laughlin Richard Mc , Huget E.F.
Published: November 2010

Substitution of aluminum oxide for fused quartz in zinc oxide-eugenol-o-ethoxybenzoic acid cements improved compressive strength and lessened film thickness. Physical properties were similar to those of zinc phosphate cement. The material is useful clinically for crown and bridge cementation. for insulating bases, and for temporary restorations.
Dental Silicate Cements: VI. Infrared Studies
Authors: Wilson Alan D. , Mesley Robert J.
Published: November 2010

Infrared studies have shown that silica gel and H2PO4-1 ions are formed in fresh cement paste. Subsequently, during setting and hardening, H 2PO4-1 ions further react to form covalent phosphates and are removed from the system. In an uncertified cement, H2PO 4-1 ions were found in substantial amounts even in the set cement, which accounted for poor strength and durability.
Nature of Attachment Forces in Porcelain-Gold Systems
Authors: Vickery R.C. , Badinelli L.A.
Published: November 2010

Chemical bonding between gold and porcelain takes place only through interstitial compounds essentially located at grain boundaries in the metal. No evidence is found for meaningful contribution of Van der Waal's forces. The major attachment force in porcelain-gold prostheses without an intervening bonding agent is derived from compression forces generated by differences in thermal expansion of the two phases.

Anaerobic Glycolysis in Bovine Dental Pulp
Authors: Fisher Alton K. , Walters Victor E.
Published: November 2010

Anaerobic glycolysis in bovine dental pulp was measured manometrically by the bicarbonate method. It is most prominent in dentinogenically active pulp. Although reasonably high initial activity seems possible. the rate of glycolysis declines rapidly under anaerobic conditions. Substrate concentration directly influences the speed of deterioration of the glycolytic rate. It is suggested that continued glycolysis is dependent on aerobic metabolism.
Pharmacologic Control of Dentinal Fluid Movement and Dental Caries in Rats
Authors: Steinman Ralph R.
Published: November 2010

Parasympathetic stimulants were found to encourage the movement of fluid through the dentin from the pulp to the dentinoenamel junction. Regular treatment with a parasympathetic stimulant in rats that had all their major salivary glands removed significantly reduced the incidence of dental caries. Treatment with bradykinin in rats on a noncariogenic diet encouraged the movement of fluid into the tooth. When given regularly for 15 weeks, bradykinin caused significant dental caries.

Influence of Some Steroid Contraceptives on Incidence of Dental Caries and Changes in Salivary Glands in Female Rats
Authors: Liu Frank T.Y.
Published: November 2010

The synthetic steroid contraceptives, norethynodrel and mestranol, were injected subcutaneously beginning at weanling or pubertal age, into female rats. With increased doses of steroid(s), the caries incidence proportionally increased and with increased frequency of administration and duration of treatment, the total cariogenic dose of the steroid(s) decreased by 95%. A synergistic, or at least an additive, cariogenic effect existed between the two steroids. Absolute and relative salivary glandular weights decreased and increased, respectively, on administration of the steroid. Both the diameter of and relative number of submandibular granular tubules decreased as compared with those of the controls.
Use of Hyaluronic Acid and Chondroitin Sulfate by Bacterial Isolates from Carious Dentin
Authors: Toto Patrick D. , Santangelo Mario V. , Madonia John V.
Published: November 2010

Streptococcus isolated from human carious dentin can derive its carbon solely from a medium composed of a salt solution with added chondroitin sulfate or hyaluronic acid. The growth is inhibited by sodium fluoride. It is suggested that carious dentin results from streptococcal hydrolysis of dentin polysaccharides.

Authors: Gedalia I. , Azaz B. , Schmerling M.
Published: November 2010

Citrate content was determined in the outer surface enamel of unerupted human teeth. The citrate content of the outer surface enamel of erupted teeth was higher than that of unerupted teeth, suggesting that citrate is absorbed from the oral environment after eruption of the teeth. No inverse correlation was found between the citrate and fluoride content of the surface enamel of erupted teeth.
