In this regard, there are different methods to manufacture novel nano-structured dental materials, and also modern drug delivery techniques. In this review article, all our efforts are based on the recently nano-dental approaches closely linked to treat or prevent some common dental diseases including tooth erosion, tooth sensitivity, periodontal disease, oral cancer, and so on. All the data and articles putted in this survey are gathered from Google Scholar, PubMed, and some dental databases.展开更多

In particular, examples on the use of nanoindentation technique in investigating the effects of cleansing and bleaching agents as well as drinks on the micro- and nanostructures and mechanical properties of teeth are highlighted. Although nanoindentation on teeth is a relatively new area of research, it provides an excellent way of probing and relating the structures and mechanical properties of teeth at the submicron and nanometer scales that were previously not possible but which can now greatly benefit dental research. For example, a nanoindenter with a high resolution imaging capability can help to elucidate the mechanisms with which certain diseases can damage and compromise the structural integrity of teeth at the micro- and nanometer scale. With this information, clinicians and researchers can then work towards how best to tackle these problems or even preventing them.展开更多

There has been an increase in the interest of researchers in the state of the oral health because of the deleterious effects a poor oral health can have on the general health. While the prevalence of oral diseases has been reported to be on the increase worldwide, this paper presents a report on the prevalence of oral diseases in 10 rural communities known as Oke-ogun communities in Oyo State of Nigeria. Cleft and Facial Deformity Foundation (CFDF), an indigenous non-governmental organization (NGO) organized an outreach program, with permission from the State Health Ministry, to examine, diagnose dental diseases, and carry out free surgeries for patients in the visited communities. The program was for two weeks and was divided in phases with the first phase done in May 2019 and second phase in September 2019. Among 1396 respondents, 43.6% complained of toothaches with more female than male presenting with that complain. Also, 511 (36.6%) were reported to have gingivitis and 51 (3.7%) had dental caries. Furthermore, gingivitis and chronic periodontitis were more common in males 776 (55.6%) than females 620 (44.4%) and this was statistically significant at ≤0.002. Periodontal disease was found to be more prevalent in Oke-ogun communities in Oyo state, and this called for urgent intervention strategies by the federal government of Nigeria, non-governmental organizations (NGO) and the international organizations like the World Health Organization (WHO) since the poor oral health would eventually translate to poor general health.展开更多

Existing systems used few symptoms for dental diagnosis. In Dentistry, few symptoms are not enough for diagnosis. In this research, a conditional probability model (Bayes rule) was developed with increased number of symptoms associated with a disease for diagnosis. A test set of recurrent cases was then used to test the diagnostic capacity of the system. The generated diagnosis matched that of the human experts. The system was also tested for its capacity to handle uncommon dental diseases and the system portrayed useful potential.展开更多
