Official title
Evaluation of Oral Hygiene Status in Correlation With Microbial Load in the Oral Cavity Following Restorations of Primary Molars Using Stainless Steel and Bioflex Crowns (Clinical Randomized Trial)
Overview
Following the restoration of primary molars with stainless steel and bioflex crowns, an evaluation of the current state of oral hygiene in relation to the amount of microorganisms and gingival health in the oral cavity will be carried out.
Interventions
- Other stainless steel crown
familiar method of managing multi-surface carious lesions in primary teeth - Other bioflex crown
aesthetic preformed pediatric crowns that offer the properties of both stainless steel and zirconia crowns
Primary outcome measures
- The adhesion of S. mutans to prefabricated Bioflx and Stainless-steel crowns under clinical conditions. [Time frame: one months]
Secondary outcome measures (2)
- Gingival health [Time frame: one months]
- Plaque Index (PI) [Time frame: one month]
