摘要:

AbstractThere is growing evidence that the basal layer of stratified squamous epithelia consists of cells of differing proliferative capacities and behaviour. These can be classified as stem cells transient amplifying cells and post‐mitotic maturing cells, the most important of which appear to be the stem cells which may be present throughout life and are responsible for all cell production under steady‐state conditions. Recent stem cell concepts are reviewed for epidermis, intestinal crypt and oral mucosa and are compared with tissues such as bone marrow and testes which have for some time been thought to operate in a similar manner. These concepts are applied to several pathological conditions of oral epithelia in an attempt to explain some of the changes obser

摘要:

AbstractLabial surfaces of bovine incisor enamel, after weak acid demineralization, were exposed for 24 h in solutions that contained trace levels of calcium as45Ca, 0.4 mM NaF, and 1.0 mM MgCl2at pH 7.0. The solutions approached saturation with apatites in the absence of NaF, and saturation with fluorapatites in the presence of NaF. NaF greatly increased the exchange of45Ca. MgCl2decreased45Ca exchange, but had no effect on F−exchange in the surface minerals. MgCl2decreased, while NaF increased the acid resistance of the exchanged surface minerals on later exposure to 10 mM acetic acid at pH 4.5. These results indicated that magnesium in oral fluids and tooth minerals may promote carie

摘要:

AbstractConsiderable effort has been made in the past to describe the morphologic changes in dentin which characterize various developmental disturbances of teeth. However, there appears to be no previous attempt to describe the spectrum of changes which may be exhibited by abnormal dentin. This paper presents a classification of dysplastic forms of dentin with definitions and illustrations of each abnormality. The classification was derived from reviewing the literature and from a study of 82 odontomas, examples of specific developmental disorders of dentin, regional odontodysplasia, and systemic conditions affecting dentin.

摘要:

AbstractThe habit of chewing tobacco along with lime in the canine‐premolar region of the mandibular groove is widespread (28%) in the rural population of Maharashtra, India. Among individuals with this habit, a thick yellowish‐white‐to‐brown lesion was observed at the site of placement of the mixture. Unlike leukoplakia, this lesion could be scraped off. The prevalence of this lesion among 101,761 Maharashtrian villagers was 2.9% which is four times more common than leukoplakia (0.67%). It is surmised that this particular lesion among the tabacco‐lime users is a specific entity with consistent histological features. The diagnosis should be made on the basis of history, clinical features, and consistent histologica

摘要:

AbstractPlaque‐like lesions of the oral mucosa have been observed in seven immunosuppressed renal transplant patients. Whilst bearing a superficial resemblance to acute pseudomembranous candidiasis (thrush), these lesions have been shown to be associated with bacterial overgrowth and not with fungi. Treatment has depended on the use of appropriate antibiotics and antiseptics together with the adoption of measures to cause disintegration of the mucoid matrix of the lesion

摘要:

AbstractThe use of the carbon dioxide (CO2) laser for sterilization of metal instruments was investigated. Scalpel blades contaminated with bacterial spores were exposed to the laser and subsequently cultured. Our results demonstrate that the CO2laser effectively sterilizes metal Instruments.
