EndodonticsRadiographic evidence of bone filling in periapical lesions typically becomes apparent 8-12 months after successful endodontic treatment. Earlier time frames show soft tissue healing, while complete bone regeneration requires this longer period.

EndodonticsReversible pulpitis is a mild inflammation of the dental pulp that is typically relieved by the application of cold water or air. The transient pain is caused by the movement of fluid within the dentinal tubules when exposed to stimuli, which is consistent with the hydrodynamic theory of pain.

The ceramic used in porcelain fused to metal (PFM) restorations consists of low fusing porcelain.
Low fusing porcelains have a firing temperature range of approximately 850–1100°C (1562–2012°F)

The enamel in primary teeth often has an aprismatic and wavy orientation, which necessitates a longer etching time to achieve proper bonding.

1. The use of adhesive sealants: Adhesive sealants are thin, plastic coatings
applied to the chewing surfaces of the back teeth. They fill in the grooves and
depressions, creating a smooth surface that is easier to clean. Sealants act as
a barrier, preventing food and bacteria from lodging in these areas and thus
reducing the risk of tooth decay. This is considered the best preventive measure
because it directly addresses the anatomical vulnerability of the teeth and can
be applied quickly and painlessly.
2. Topical fluoride application: While topical fluoride is beneficial in
preventing dental cavities, it is not as effective as sealants in preventing pit
and fissure caries. Fluoride helps to strengthen the enamel and makes it more
resistant to acid attacks from plaque bacteria. However, because the pits and
fissures are already deep and narrow, fluoride may not always reach these areas
effectively. Sealants, on the other hand, provide a physical barrier that
fluoride cannot always penetrate.
