About

white spot lesions are a common problem and are reported in up to 96% of orthodontic patients. In this study, the preventive effect of bioactive gel is evaluated in comparison to fluoride.

Full description

Dental caries is a chronic infectious disease present worldwide and is among one of the most common oral diseases. It is a multifactorial disease resulting from imbalance between demineralization and remineralization initiated by acid producing bacteria in the microenvironment.

The incipient form of caries, white spot lesions (WSL), is characterized by primitive enamel surface and subsurface demineralization and could be identified clinically by their chalky white appearance . Orthodontic treatment is a major risk factor for the development of WSL. They are reported in up to 96% of orthodontic patients.

Many materials are being used to prevent white spot lesions with fluoride being the most commonly used . New materials have been emerged such as giomer based bioactive gel with the ability to release six ions Fluoride inhibits demineralization and promotes deposition of fluoroapatite. Aluminum helps to decrease demineralization as well by forming Alumino fluoro complexes. Borate reduces biofilm formation beside its antibacterial effect.

Silica promotes remineralization by inducing apatite nucleation on the tooth surface. Strontium converts hydroxyapatite into strontium apatite thus increasing acid resistance and has an inhibitory effect on bacterial growth. Other ions such as Na act as strong base and have acid buffer capacity.

330 participants in 2 patient groups

Application of bioactive gel on teeth in patients assigned for orthodontic treatment

Experimental group

Description:

Application of bioactive gel on labial/buccal surfaces of teeth is done according to manufacturer instructions using microbrush followed by light curing

Treatment:

Drug: giomer based bioactive gel

Application of Fluoride on teeth in patients assigned for orthodontic treatment

Active Comparator group

Description:

Application of fluoride gel will be done using a gel loaded tray held in the mouth for 4 minutes .After removal of tray ,patients must spit out the residual gel. The use of suction is a must to avoid the problem of over ingestion

Treatment:

Drug: Fluoride gel
