Evaluation of the remineralisation potential of bioactive glass, nanohydroxyapatite and casein phosphopeptide-amorphous calcium phosphate fluoride-based toothpastes on enamel erosion lesion -An study.

Indian J Dent Res 2020 Sep-Oct;31(5):670-677

Department of Conservative Dentistry and Endodontics, JSS Dental College and Hospital, JSS Academy of Higher Education and Research, JSS Medical Institutions Campus, Sri Shivarathreeshwara Nagar, Mysuru, Karnataka, India.

Background: Erosion, a dynamic process with periods of demineralisation and remineralisation, has become a common problem in modern societies, owing to changes in life style and dietary habits. Although fluorides have been included in toothpastes that claim to prevent demineralisation and aid remineralisation, their ability to remineralise is limited by low concentration of calcium and phosphate ions available in saliva. Hence, a new paste based on casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF), nanohydroxyapatite and bioactive glass (BAG) were introduced. Read More

The comparison of the effects of different whitening toothpastes on the micro hardness of a nano hybrid composite resin.

J Conserv Dent 2014 Nov;17(6):550-4

Department of Mechanical Engineering, Reva Institute of Technology and Management, Bangalore, Karnataka, India.

Aim: The aim of this study was to compare the micro hardness of a nanohybrid composite resin after brushing with two herbal and one non-herbal whitening toothpastes.

Materials And Methods: We divided Eighty disk-shaped specimens of a nanohybrid composite (Tetric N Ceram, Ivoclar Vivadent, Asia) into 4 groups of 20 specimens each: Groups A, B, C, and D. Group A was control, Group B was brushed with Colgate total advanced whitening (Colgate-Palmolive (India) Limited), Group C with Salt and Lemon, Dabur (Dabur International Limited, Dubai, UAE), and Group D with HiOra Shine, Himalaya (The Himalaya Drug Company, India).

Toothpaste and erosion.

Monogr Oral Sci 2013 28;23:88-99. Epub 2013 Jun 28.

Department of Conservative and Preventive Dentistry, Dental Clinic, Justus Liebig University, Giessen, Germany.

Dental erosion develops from the chronic exposure to non-bacterial acids resulting in bulk mineral loss with a partly demineralised surface of reduced micro-hardness. Clinical features are loss of surface structures with shallow lesions on smooth surfaces and cupping and flattening of cusps; already in early stages, coronal dentine often is exposed. Not only enamel, but also dentine is therefore an important target tissue for anti-erosion strategies. Read More

The in vitro demineralization potential of a sodium fluoride, calcium and phosphate ion-containing dentifrice under various experimental conditions.

J Clin Dent 1999 ;10(1 Spec No):22-5

Digestive Care, Inc., Bethlehem, PA, USA.

While fluoride has had a dramatic effect in reducing the rate of caries, it has failed to provide complete protection against caries development, and tooth decay is still widely prevalent. The objective of this study was to determine the demineralization prevention potential of a remineralizing dentifrice with fluoride (Enamelon), and an assured supply of calcium and phosphate ions on bovine enamel in a cyclic remin/demin regimen using various experimental conditions. A conventional fluoride toothpaste, Crest, and a placebo dentifrice were used as controls. Read More
