Prospects of oral disease control in the future - an opinion
The mouth supports a diverse microbiota which provides major benefits to the host. On occasions, this symbiotic relationship breaks down (dysbiosis), and disease can be a consequence. We argue that progress in the control of oral diseases will depend on a paradigm shift away from approaches that have proved successful in medicine for many diseases with a specific microbial aetiology. Factors th...

Association of salivary triglycerides and cholesterol with dental caries in children with type 1 diabetes mellitus
Metabolic disturbances in diabetes mellitus can affect oral health. Altered levels of salivary lipids have been suggested as a risk for dental caries. There has been lack of research in this regard and in children with type 1 diabetes mellitus. To assess the salivary triglycerides and cholesterol levels in children with type 1 diabetes mellitus and correlate them with their dental caries status...
A practical approach to evidence-based dentistry: How to search for evidence to inform clinical decisions
