PeriodonticsThe response to periodontal probing is a reliable method to differentiate
between an acute periapical abscess and an acute periodontal abscess. An acute
periapical abscess typically does not show significant probing depth changes,
while a periodontal abscess may show increased probing depths due to periodontal
tissue involvement.

Dental MaterialsPlatinized gold foil is a combination of gold and platinum where 15% of the content is platinum. It is produced by rolling layers of gold and platinum together to achieve the desired thickness and distribution of the platinum within the gold foil. This process creates a homogeneous mixture that enhances the hardness and wear resistance of the restoration, making it suitable for high-stress areas like incisal edges and cusp tips.
