Bacterial colonization of teeth occurs in stages. Primary colonizers, such as Streptococcus and Actinomyces species, attach directly to the tooth surface. Secondary colonizers, such as Campylobacter species, Porphyromonas gingivalis, and Fusobacterium nucleatum, adhere to the bacteria already present on the tooth surface rather than the tooth itself.

Scratches on an intensifying screen block the light from reaching the film in that specific area during exposure. This results in an under-exposed area on the radiograph, which appears as a light spot.

NEETMDSThe function of a fixer solution in radiographic film processing is to dissolve and remove the unexposed silver halide crystals from the film emulsion. This process "fixes" the image, making it permanent and preventing the remaining silver from darkening when exposed to light.

Ist investments flow contain the α-hemihydrate of gypsum. because greater strength is obtained. This gypsum A slight expansion takes place between 400°C and approximately 700°C (1292°F). and then a large contraction occurs. This later shrinkage is most likely caused by decomposition and release of sulphur gases, such as sulphur dioxide. This decomposition not only causes shrinkage but also contaminates the casting with the sulphides of the nonnohlc alloying elements, such as silver and copper. Thus, it is imperative that gypsum investments should not be heated above 700°C (1292°F). however, for gypsum products containing carbon, the maximum temperature should be 650°C (1202°F). In this way, proper ut and uncontaminated alloys are obtained.
Gypsum-bonded investments are used for gold alloys. The essential ingredients of the dental inlay investment employed with the conventional gold casting alloys are α-hemihydrate of gypsum, quartz or cristobalite. which are allotropic forms of silica.
product serves as a binder to hold other ingredients together and provide rigidity. The strength of the investment is dependent on the amount of binder present.
