Early Childhood CariesNCT04765904
Clinical Efficiency and Treatment Failure of Hall Versus SDF Techniques in the Management of Carious Primary Molar.
A study testing SDF and Hall technique in people with Early Childhood Caries, run by Cairo University.
Trial 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.

About this study
Official title: Clinical Efficiency and Treatment Failure of Hall Versus SDF Techniques in the Management of Carious Primary Molar: Randomized Clinical Trial.
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.
Read the 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)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SDFProcedure or surgery
Also called Silver Diamine Fluoride
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
Hall techniqueProcedure or surgery
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
| Study group | Role | What they receive |
|---|---|---|
| Hall Technique | Active comparator | The Hall Technique is a non-invasive treatment for decayed molar teeth. Decay is sealed under preformed (stainless steel) crowns, avoiding drilling Receives: Procedure: Hall technique |
| SDF | Experimental | 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 Receives: Procedure: SDF |
What is being measured
The primary outcome is the main question the study is designed to answer.
percentage of Treatment failure:
- Obvious furcation or periapical radiolucency by radiographic examination.
- (Internal and external) resorption by radiographic examination.
- Sensitivity to percussion by clinical examination ( dental mirror ).
- Loss of SSC crown by clinical examination ( visual examination ).
Measured: one year
Secondary outcomes (2)
Canine overbite
measure the canine over bite discrepancy by Boley Gauge by Millimeter
Measured: one year
Arresting caries in SDF
assess caries activity according to (ICDAS) through Codes 0-1-2-3-4-5-6
Measured: one year
