Lyophilyzed 19-day-old rat fetuses, implanted next to the periosteum, induced bone growth in mature rats. The initially immature bone matured after three weeks to the pseudo-haversian bone peculiar to the rat. The induced bone remained stable for 12 weeks. With the exception of one contaminated specimen, there was no foreign-body reaction.
Morphogenesis of Mandibular Dental Arch Shape in Human Embryos
Authors: Burdi Alphonse R.
Published: November 2010

Changes in shape of the mandibular dental arch were demonstrated in a developmentally representative sample of human embryos. Each reconstructed arch was described in terms of a conformance to a reference geometric curve; ie, catenary. Cross-sectional sample trends showed that the initial dental lamina is anteroposteriorly flattened during the sixth week and begins a progressive elongation and conformance to the catenary curve in 8½-week embryos.

Authors: Debrot Adolphe
Published: November 2010

In a sample of 4,330 Negro elementary school children, the eruption sequences of the permanent canine, first premolar, and second premolar were studied from observations on the groupings in which these three teeth occur. A model was constructed by which the proportionate occurrence of each eruption sequence can be predicted.
Oxygen Uptake of Rat Incisor Pulp After Hypophysectomy
Authors: Kozam George
Published: November 2010

The mean reduction in oxygen uptake of incisor pulp from 142 hypophysectomized rats was 10.2%. This figure is significant in the negative sense, in that it demonstrates a relatively undisturbed physiologic pattern of pulp. This finding coincides with the histologic findings of others, that hypophysectomy disturbs the enamel organ, resulting in a lack of enamel formation and eruption, but spares the dentin-forming properties of pulp, resulting in the intrapulpal folding of dentin.

Authors: Gardner Alvin F.
Published: November 2010

A Mikulicz-like disease of the lacrimal glands occurred after six weekly subcutaneous injections of 10 mg of 5-hydroxytryptamine. The lacrimal glands of all experimental rats developed a dense lymphocytic infiltration that caused destruction of acinar cells.
Strength of Capillaries in Oral Mucous Membranes
Authors: Kozam George
Published: November 2010

The suction method was used to test the capillary resistance of oral mucous membranes. The labial mucosa was found to be suited to capillary resistance studies since it lacks both pigment and cornification, and the petechial hemorrhages are easily visualized. The minute vessels of the lower labial mucosa were significantly stronger at -50, -100, -200, -300 and -400 mm Hg than were those of the skin of the antecubital fossae. It is now possible to recognize subjects of high, low, and intermediate capillary resistance.

Saliva-infected rat incisor pulp was capped with lyophilized dentin chips mixed with prednisolone and neomycin. The mixture prevented development of inflammation in this tissue. In several teeth, even mineralized bridge formation was observed.
Effect of Beta-2-Thienylalanine on Developing Mouse Tooth Germs In Vitro
Authors: Kollar Edward J. , Baird Grace R.
Published: November 2010

Tooth germs grown on Eagle's medium solidified with agar will differentiate in vitro. Normal development was suppressed by beta-2-thienylalanine (1 or 2 millimols per liter), but it proceeded when phenylalanine and beta-2-thienylalanine were present in equimolar concentrations. This effect may have been due to interference with protein metabolism in the dermal papillar cells.

Authors: Azar Emile S. , Welk Donald A. , Stibbs Gerald D. , Hodson Jean T.
Published: November 2010

Amalgam adaptation into axial line angles was investigated. Split metal dies, providing line angles of 30°, 45°, 60°, and 90°, were used to prepare the specimens. The area of discrepancy between the packed amalgam and test line angles was measured. Adaptation improved significantly as the degree of line angle increased.
Dental Caries in Deciduous Teeth of Nineteenth Century Araucanians
Authors: Devoto Francisco C.H. , Bordoni Noemi E. , De Manfredi Clelia F.
Published: November 2010

The prevalence of dental caries was studied in skulls of nineteenth century Araucanian children from the Argentine provinces of Buenos Aires and La Pampa. The results were contrasted with those from a contemporary sample of Caucasian children from the city of Buenos Aires. Significantly higher values were found in the Caucasian sample. The nature of the diet and the fluoride content of the water seemed to be more decisive than racial and genetic structure in explaining these differences.
Deformation of Amalgam by Indenters
Authors: Braden Michael
Published: November 2010

Using steel spherical indenters, the relationship between indentation diameter and load was determined for a mature amalgam. The form of this relationship allowed the regions of elastic and plastic deformation to be identified; hence, Young's modulus and yield point could be calculated. Local contact stresses in the mouth also were estimated.

Authors: Piebenga L.W. , Shiller W.R.
Published: November 2010

Calculus formation rates were evaluated in men living in closed, elevated CO2 environments of submarines. These rates were compared with values obtained prior to submarine patrol duty. The standardized Mylar foil technic was employed to collect calculus from the lower anterior teeth. Analysis revealed no significant differences between the prepatrol and patrol values and the formation rate and component values were well within formerly reported limits.
Role of Attrition and Occlusal Contact in the Physiology of the Rat Incisor: III. Prevention of Attrition and Occlusal Contact in the Nonarticulating Incisor
Authors: Michaeli Y. , Weinreb M.M.
Published: November 2010

Removal of occlusal contact in the absence of attrition liberates the growth potential of the rat incisor, which is expressed in a doubled rate of axial growth and eruption. The differentiation times, the life spans and the rates of apposition of dental hard tissue-forming cells, however, are independent of the rates of growth and eruption.

Authors: Cserepfalvi Miklos , Price Paul J.
Published: November 2010

A premolar from a 10-year-old boy was transplanted to the lower jaw of a 7-lb male rhesus monkey. Ten months after transplantation, the tooth was still in perfect functional condition. There was evidence of ankylosis, and the surrounding gingival tissue was healthy.
Development of Caries in the Hunt-Hoppert Caries-Susceptible and Caries-Resistant Rats Under Different Experimental Conditions
Authors: Larson Rachel H. , Keyes Paul H. , Goss Bette Joan
Published: November 2010

Rats of both Hunt-Hoppert lines, originally designated as caries-susceptible (Ca-S) and caries-resistant (Ca-R) lines, were highly susceptible to caries when subjected to a combination of diet and microflora that provided a challenge to the resistance of all surfaces of the teeth. Strain differences were indicated by the predominance of sulcal lesions in the Ca-S line and smooth-surface lesions in the Ca-R line.

Enamel fluoride progressively increased as the number of treatments increased, reaching a concentration of 1,785 ppm at a depth of 5μ after an average of 56 treatments.
Caries Development in the African White-Tailed Rat (Mystromys albicaudatus) Infected with a Streptococcus of Human Origin
Authors: Larson Rachel H. , Fitzgerald Robert J.
Published: November 2010

The African white-tailed rat (Mystromys albicaudatus) developed rampant dental caries when challenge was made with a combination of diet 2000 and a streptococcus of human origin (KI-R). The apparent lack of caries in certain species may result from the absence of a microbial and dietary challenge, rather than inherent resistance to the disease.

Authors: Lavelle C.L.B.
Published: November 2010

Estimation of the dimensions of Anglo-Saxon and modern permanent dentitions provided the basis of this investigation. The premolars, canines, and incisors of Anglo-Saxons appeared larger than those of contemporary subjects. The reverse was true for the molars. These changing tooth dimensions may contribute to the increasing prevalence of dental overcrowding.

Authors: Thomas J.A. , Mason W. , Mawhinney M.
Published: November 2010

Ethionine administration (300 or 600 mglkg daily for 5 or 11 days) produced significant reductions in submaxillary protein levels in normal mice. These reductions were not observed in these same tissues obtained from castrated mice treated with testosterone. Ethionine-induced changes in submaxillary ribonucleic acid (RNA) were also evident.
Investigation on the Expansion of Dental Stone
Authors: Lautenschlager E.P. , Corbin F.
Published: November 2010

Calculations based on apparent density measurements and X-ray diffraction data indicated that the porosity of dental stone arose from evaporation of excess water and from micropores created by crystal impingement. The volume of these created micropores was directly related to the linear expansion of the stone.
