Study Description

Brief Summary

There is still a need for the assessment of different minimal intervention strategies and treatments focusing on the prevention and arrest of carious lesions of primary molars The evidence-based clinical practice guideline on non-restorative treatments for cavitated carious lesions advocate the use of silver diammine fluoride biannually for high caries risk patients

Detailed Description

Although SDF has been proven to be highly effective in carious lesion arrest and prevention, the staining effect, metallic taste due to silver content and the minimal mucosal irritation have been noted as primary cause of disinterest among clinicians in the use of this material.

The use of NaF-fTCP as a caries preventive material has not been studied widely. The importance of oral hygiene education and diet modification to achieve an effective caries control has been widely discussed. The off-label use of NaF-fTCP as a caries arresting agent has not been studied on primary dentition. There is a dearth of evidence regarding the effectiveness of NaF-fTCP towards caries arrest and prevention in pragmatic settings.

A comparison between the SDF and NaF-fTCP application on the cavitated carious primary molars and their effect on the oral health-related quality of life of the children has not been published in the literature.

Arms and Interventions

Arm	Intervention/Treatment
Active Comparator: Topical application of 38% Silver Diammine Fluoride Solution at Baseline SDF is known for its corrosive nature therefore a plastic container or dappen dish will be used. 1 drop (0.05 ml) will be dispensed on a plastic container. 1 drop (2.24 F-ion mg/dose) SDF treats up to 5 tooth surfaces. Ultrafine microbrushes will be used to apply varnish.	Drug: Topical application of 38% Silver Diammine Fluoride Solution Application of petroleum jelly on lips and around the mouth for prevention of temporary silver tattoo. Before SDF application, the affected area will be thoroughly dried and isolated using the cotton rolls or dri-angle. Isolation throughout the procedure and following three minutes is considered most desirable. The varnish should be allowed to be in place for 60 seconds. This is the most critical step in the process. Applied varnish will be dried with gentle flow of compressed air. SDF will be applied with a microbrush to all carious lesions and to all pits and fissures on posterior (molar) teeth for 60 seconds. To avoid gingival or mucosal irritation, contact of varnish with any oral tissue other than affected area will be avoided. If the application time is shorter due to unforeseen reasons reapplication will be considered. Other Names: Riva Star 38% Silver Diammine fluoride SDF Advanatge Arrest Saforide

Experimental: Topical application of 5% Sodium Fluoride with functional Tricalcium phosphate Varnish at baseline 0.25 ml of the solution will be used which contains 12.5 mg of fluoride. Thin layer will be applied with sweeping horizontal brush strokes to all teeth present.	Drug: Topical application of 5% Sodium Fluoride with functional Tricalcium phosphate Varnish According to manufacturer, Clinpro® White Varnish can be applied to tooth surfaces where plaque is present. A prophylaxis is not required. The applicator brush provided along is used to thoroughly mix the varnish inside the single-unit dose pack, since components of all sodium fluoride varnishes are separate during storage. Excessive contact with soft tissue should be avoided. Only enough varnish to form a thin coating on the desired treatment area should be used. After application, patient should be instructed to close their mouth to set the varnish. Rinsing or suctioning immediately after application is not recommended. The operator might appreciate the formation of a thin coating on the teeth and the patient should be informed that they may feel a thin coating when rubbing the treated area with their tongue.
