The Relation Between Oral Hygiene and Microbial Load in the Oral Cavity After Restoring Primary Molars With Two Types of Ready-made Crowns

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)

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.

Inclusion Criteria:

• Participants aged between 4 and 8 years.
• Pulp therapy treated primary molars on the contralateral side, requiring a full coverage restoration (split-mouth technique).
• No history of any antibiotic consumption 2 weeks before the procedure.
• No history of fluoride application 2 weeks before the procedure.

Exclusion Criteria:

• Special children with physical disabilities or emotional disturbances.
• Children are diagnosed with systemic diseases.
• Grossly destructed teeth with non-restorable crown structure.
