Over the years dental health has assumed parallel significance and importance besides general health services rather than as its constituent part. Public health policies on oral health are being increasingly emphasized. Dental care is now being included in health insurance coverage. However, National level policies on financing and provision of resources for dental services are yet to gain prominence. Development of effective and reliable treatment procedures is fundamental for enhanced funding in dental health sector.
There have been significant advancements in the treatment procedure and the materials used in dental care in the recent years. Our tooth is very complex in its anatomy and dentin forms the bulk of its composition. Both in terms of weight and volume, dentin is primarily composed of mineral phase and organic matter. Dentin is even more mineralized than the bone.
Dental caries and periodontal diseases are the major forms of oral disorders. Dental caries, lesions, and fractures lead to loss of dental structure. Currently the restoration is achieved by infiltration of synthetic polymers into demineralized collagen fibers of dentin. However, hydrolysis of the monomers is a greater challenge. Action of endogenous proteases is also a cause of concern. The resin based restorations is very cost-intensive. In this context researchers from Brazil have reviewed promising techniques and material to improve the stability of restorations. The study published in Oral Health and Dental Management revealed that proanthocyanidins obtained from natural extracts of tea leaves, cinnamon bark, acai fruit and pine bark as well as cardol and cardanol from cashew nuts are good choice as biological modifiers of dentin while those of synthetic origin have cytotoxic effects. Their multiple interactions with dentin components are regarded as important for bio-mechanical strength and bio-stability of restored teeth. Glass fiber has been successfully used for restoration purpose. Another study group from Brazil reported a study on the bond strength of fiber post with root dentin as influenced by irrigation solution and found ethylenediaminetetraacetic acid (EDTA) as best irrigation solution achieving reliable bond strength.
These research reports appeared in Longdom Publications and are of immense relevance in achieving efficiency and efficacy in most common dental restoration/treatment procedures as they focus on strengthening the teeth and sustaining their bio-mechanical function and biological stability.
