摘要:

Abstract—A range of selective media was used to culture the microbial flora of the dental plaque, tongue and palate. The subjects were five young men who smoked more than twenty cigarettes a day and four who did not smoke. Neisseriae were less numerous on the mucosal surfaces of the smoker

摘要:

Abstract—A method has been evolved for bonding aluminous porcelain to pure platinum foil used for making porcelain crowns by the conventional ‘tinner's joint‘ technique. It was found that good bonding was achieved when the platinum was coated with 0.2–2.0 μm of tin before firing on the porcelain. This paper describes experimental work for determining the optimum composition and thickness of the coating and the applicability of the technique to substrates other than

摘要:

Abstract—Acid phosphatase levels in serum from 5 patients with prostatic carcinoma were diagnostically higher than those from 5 patients who had undergone prostatectomy. The levels for saliva when compared with those from normal subjects for stimulated (314) and unstimulated (50) salivas could not serve as an index of serum concentratio

摘要:

Abstract—Plaque samples from 27 buccal tooth surfaces were obtained with sterile McCall curettes from available third molars. Bacteriological sampling and biochemical tests were carried out to identify four groups of streptococci, i.e.Str. mutans, Str.spp.,Str. sanguisandStr. mitis.Clinical examinations carried out 6 months after the dental scrapings were taken showed a strong positive correlation between detectable lesions andStr. mutan

摘要:

Abstract—A survey of over 2,000 second year high school students at 13 South Australian schools indicated that those who had received school dental care at primary school had fewer carious teeth and, in some respects, better oral hygiene habits. Whilst they were better informed on dental subjects than were control students, fewer had attended a private dentist since leaving primary schoo

摘要:

Abstract—Eleven base forming materials used under amalgam restorations were examined for the rate of development of their compressive and tensile strengths. Materials from three categories were compared.Underin vitroconditions of testing, it was found that, immediately after a state of clinical set had been reached, the quick‐setting zinc oxide‐eugenol materials possessed strengths significantly greater than the calcium hydroxide cements but significantly weaker than the zinc phosphate cements.Calcium hydroxide cements possessed the lowest compressive strength to tensile strength ratio and modified zinc oxide‐eugenol materials the

摘要:

Abstract—It is known that porous solids such as Portland cement, concrete, and ceramic tile bodies can be strengthened by polymer impregnation. The solid material is infiltrated with a liquid monomer, which is then polymerizedin situ.In the present investigation, it has been found that this process is effective for strengthening gypsum casts prepared from ordinary laboratory plaster. Impregnation with poly(methyl methacrylate) confers marked improvements in tensile and compressive strength and abrasion resistance. The process would be particularly applicable to the preservation of study casts for record purpose
