The management of deep carious lesions approaching a healthy pulp is considered a challenge to the dental practitioner. The conventional treatment of deep carious lesions requires the removal of all infected and affected dentin to avoid more cariogenic activity.

This study is designed to assess the clinical and radiographic effectivness of nano silver fluoride versus calcium hydroxide in an indirect pulp treatment of deep carious second primary molars. This clinical study is important because World Health Organization (WHO) has reported that school children experience to dental caries was 60-90% of worldwide (P. D. Garkoti et al., 2015).

This clinical trial has potential benefits to patients where indirect pulp treatment preserves pulp vitality by partial caries removal without exposing pulp. Several materials have been used for indirect pulp technique including calcium hydroxide (Metalita M et al., 2016).

Inclusion Criteria:

Patients:

• Cooperative children.
• Both genders.
• In age range from 4 to 7 years.

Teeth:

• Vital second primary molars with deep caries limited to occlusal surface.
• No clinical signs or symptoms of irreversible pulpitis or pulp necrosis.
• No radiographic abnormalities
• Restorable teeth.

Exclusion Criteria:

• • Children with known history of allergy to any of the tested materials.

  • Children with systemic conditions.
  • Parents who refused to participate.

Clinical and Radiographic Evaluation of Nano Silver Fluoride versus Calcium Hydroxide in Indirect Pulp Treatment of Deep Carious Second Primary Molars

Eligible consented participants will be randomly assigned to know which side of the participant (right or left) will be control or intervention group according to a sequence generated on a Microsoft Excel sheet where the intervention (I) and the control (C) are simply randomized.
