Comparing the Efficacy of Different Maintenance Intervals on Preventing Disease Recurrence in Patients with A History of Periodontal Treatment.

Background: Scheduled maintenance appointments after periodontal treatment are very much critical for the success of the treatment. This is necessary for patients seeking to prevent disease recurrence and maintain oral health.

Materials And Methods: In this study, we conducted a comprehensive analysis to assess the efficacy of various maintenance intervals in preventing disease recurrence among patients with a history of periodontal treatment.

Digital assessment of marginal accuracy in ceramic crowns fabricated with different marginal finish line configurations.

Aim: To digitally evaluate the marginal adaptation of different types of all-ceramic crowns on two different marginal configurations such as Shoulder and Chamfer of the prepared teeth.

Methods: The marginal fit of the crown specimens on the model of the prepared teeth were assessed using the dual scan replica technique. Two plastic teeth were prepared; one having a Shoulder finishing line (A), while the other with a Chamfer finish line (B).
