Comparative Evaluation of Chlorhexidine and Sodium Hexametaphosphate Mouth Rinses on Dental Plaque in Children: A randomized clinical trial.

Abstract

Introduction:The use of a mouthwash augments mechanical removal of plaque by brushing and flossing and helps maintain oral health through its antiplaque and antibacterial chemical properties. Aim: to evaluate and compare clinically and microbiologically the effectiveness of chlorhexidine and sodium hexametaphosphate mouth rinses on dental plaque in children. Materials and methods: This randomized clinical trial included 40 normal apparently healthy and cooperative children aged 8 to 10 years and selected from the outpatient dental clinic of Pediatric Dentistry Department, Faculty of Dentistry, Suez Canal University. Children were randomly divided into 2 groups as follows: Group I: included (20) children who rinsed with Chlorhexidine (0.2%) and Group II: included (20) children who rinsed with Sodium Hexametaphosphate (7%). Clinical evaluation was performed by measuring gingival and plaque indices scores at all evaluation periods. Microbiological evaluation was performed by direct examination of bacterial cultures. Results: Sodium hexametaphosphate 7% mouth rinse showed a superior effect compared to chlorhexidine 0.2% mouth rinse in terms of improvement in the clinical scores and decreasing the microbial counting. Conclusion: Sodium hexametaphosphate 7% mouth rinse is a promising candidate of mouthwashes.

Antibacterial Effect of Nutmeg Extract on Cariogenic Microflora in a Group of Egyptian Children

“…As CHX is the most popular and the most effective antimicrobial agent until now, as well as it is marketed as the gold standard among all other mouthwashes (16,18) . However, due to its known shortcoming, there is a continuous need to formulate new safer mouthwashes specifically for children (8,16,19) . Therefore, herbal extracts with their active phytochemical ingredients offer the least harmful, and the most truthful alternative way for the rehabilitation of the oral health (3,10) .…”

“…Children were instructed to brush twice daily (in the morning and evening) for two weeks. Then, the enrolled children were instructed to rinse their mouth with 10 ml of the solution for 2min twice daily after tooth brushing followed by expectoration of the residual mouth rinse (18,19) . Tooth brushing and mouth rinsing techniques were demonstrated for every child.…”

Evaluation of Nanohydroxyapatite and Povidone-Iodine Mouthwashes on Salivary Streptococcus Mutans

“…Each bottle contains 50 ml to use 10 ml of the mouthwash for each application per day at morning and swish it in all quadrants of the mouth for 2 minutes for 15 days. (13) .…”

“…Then the second unstimulated saliva sample (S2) was collected from each child. For the next 15 days, all subjects were adjusted to discontinue the mouthwashes and maintain the regular tooth brushing twice daily, then, another unstimulated saliva sample (S3) was collected from each subject (12,13) .…”

“…The collected samples were prepared and cultured on the selective media "Mitis Salivarius Agar with bacitracin". The plates were incubated in an anaerobic chamber for 7 days at 37 o C. Then, the Streptococcus mutans organisms were identified and the total number of colonies on the incubated plates were digitally counted by the digital colony counter and expressed as CFU/ml (13) .…”
