Clinical Efficiency and Treatment Failure of Hall Versus SDF Techniques in the Management of Carious Primary Molar.

Study Overview
=================
Brief Summary
-----------------
This study will compare two non- invasive treatment options: Hall technique and 38% Silver diamine fluoride. Both are methods used to create a more favorable environment without removal of caries leading to the arrest of the progression of demineralization process and restoring the function of the diseased molars.

Detailed Description
-----------------
Detailed Description: Dental caries, also known as tooth decay, it can occur in primary teeth in early childhood, is formed through interaction between acid-producing bacteria and carbohydrate. The caries develops in both the crowns and roots of teeth. Progress of caries depended on the lifestyle of the child (as high numbers of cariogenic bacteria, inadequate salivary flow, insufficient fluoride exposure and poor oral hygiene). To avoid this disease should follow the proper oral hygiene and improve lifestyle . A lot of methods found to treatment the decayed tooth - like; Hall technique and Silver diamine fluoride The first report on the Hall Technique published in 2007 by a general dental practitioner from Aberdeen/Scotland, Dr. Norna Hall. Dr. Hall used PMCs to restore carious primary molars rather than using the standard technique, placed them using a simplified method2 Previous studies have recommended that Silver diamine fluoride (SDF) solution would exert a preventive result in managing early childhood caries ECC. However, no well-designed clinical trials have yet been performed to study the effect of SDF on caries prevention. the objective is useful in arresting early childhood caries (ECC)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Hall Technique<br>The Hall Technique is a non-invasive treatment for decayed molar teeth. Decay is sealed under preformed (stainless steel) crowns, avoiding drilling | Procedure: Hall technique<br>* Orthodontic separator being stretched between two pieces of floss, then placed between the contact points of primary molars (for five days.) 2)The correct size of crown will not impinge on the teeth on either side, and a slight 'spring back' will be felt when the PMC is gently pushed up<br>|
| Experimental: SDF<br>a clear liquid that combines the antibacterial effects of silver and the remineralizing effects of fluoride, is a topical therapeutic agent for managing caries lesions in young children | Procedure: SDF<br>* 1)Dry with cotton to affected tooth surfaces 2) Apply the SDF material 3)Dry with a gentle flow of compressed air for at least one minute. and Remove excess SDF with gauze<br>* Other names: Silver Diamine Fluoride;|

What is the study measuring?
