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

Al-Azhar University40 enrolled

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.

Outcomes

Primary Outcomes

The adhesion of S. mutans to prefabricated Bioflx and Stainless-steel crowns under clinical conditions.

Collecting the plaque samples from the gingival crevices, buccal mucosa, and occlusal surfaces of the teeth treated using sterile cotton swabs initially and from the respective crown surfaces. After collecting the samples, they will be inoculated onto a plate of Mitis salivarius-bacitracin agar (MSBA), a selective growth medium for cultivating S. mutans.

Time frame: one months

Secondary Outcomes

Gingival health

by measuring the gingival index (GI) Gingival Index (GI) * Purpose: Measures the severity of gingivitis based on the color, consistency, and bleeding of the gums. * Scoring: 0: Normal gingiva 1. Mild inflammation (slight change in color, slight edema, no bleeding). 2. Moderate inflammation (redness, edema, and bleeding upon probing). 3. Severe inflammation (marked redness and edema, spontaneous bleeding).

Time frame: one months

Plaque Index (PI)

* Purpose: Assesses the amount of dental plaque on teeth. * Scoring: No plaque 1. A film of plaque adhering to the free gingival margin and adjacent areas of the tooth. 2. Moderate accumulation of soft deposits on the gingival margin and/or the adjacent tooth surfaces. 3. Abundance of soft matter on the tooth and gingival margin.

Time frame: one month
