ABSTRACT
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. We gathered data from a diverse group of patients who had undergone periodontal treatment and tracked their oral health over an extended period. Results: Our findings reveal compelling insights into the optimal maintenance intervals. Patients who attended maintenance appointments at three-month intervals showed a significant reduction in disease recurrence by 40%, compared to those at six-month intervals. Moreover, those on annual intervals experienced a disease recurrence rate of 60. Conclusion: In conclusion, our study underscores the importance of regular maintenance appointments after periodontal treatment. Patients who attend appointments every three months have a significantly lower risk of disease recurrence. These findings emphasize the need for tailored maintenance schedules to ensure long-term oral health.
ABSTRACT
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). Three types of different all-ceramic crowns, layered zirconia, monolithic zirconia, and pressed lithium disilicate, were fabricated for each prepared tooth (A) and (B). Measurements for assessing the marginal discrepancy were done on four designated points on the mesial, distal, buccal, and palatal surface of the superimposed image. RESULTS: The average marginal gap was the largest in the layered zirconia group, followed by monolithic zirconia, while pressed lithium disilicate crowns showed the least marginal gaps. Crowns with Chamfer finish lines were better fitting (less marginal gap) than the shoulder finish lines across all the groups. CONCLUSIONS: Chamfer finish lines produced better fitting restorations, and heat-pressed lithium disilicate crowns showed better adaptation at the margins than both layered zirconia and monolithic zirconia.
