Prevalence and Correlates of Dental Caries in an Elderly Population in Northeast China

“…At the same age group, this observed number is higher compared to the study conducted in Australia (5.3) 13 , Turkey (7.0) 14 , but lower than the one reported in China (11.2) 8 , and Brazil (26.1) 15 . Regarding the influence of sociodemographic factors on tooth loss, participants aged 70-74 had lost significantly more teeth on average than those aged 65-69.…”

“…Our finding was close to the third China National Oral Health Survey. This survey reported that more than three-fourths of the Chinese aged 65-74 had missing teeth more often than those who regularly visited a dentist 8 . The risk factors for tooth loss have been studied all over the world.…”

Introduction: Oral health care systems for older people tend to be reducing tooth loss and saving functional dentition. Elderly Vietnamese had to live under challenging conditions and were not entitled to any dental care for over 30 years due to the Vietnam War. The aim of the current study was to investigate tooth loss and related risk factors among elderly Vietnamese aged 65-74. Methodology: The sample study was 258 elderly Vietnamese aged 65-74 years old. Each absent tooth was registered as a tooth loss. Risk factors were evaluated based on the Oral Health Questionnaire for adults (WHO, 2013). Results: The mean tooth loss for the sample was 7.6 (±7.0). 27.1% of participants had lost 1-3 teeth, 23.6% 4-6 teeth, 27.1% 7-16 teeth and 13.6% >16 teeth; 8.5% had full dentition. Within each category of predictors, a statistically higher number of lost teeth was found for: the 70-74 age group (Mean±SD, 8.8±7.9); rural residents (8.8±7.6); time in education ≤5 years (10.2±7.7); frequency of teeth cleaning ≤1 time/day (8.7±7.3); last visit to dentist >1 year ago (8.2±7.5); tobacco smoking (9.4±7.6); no alcohol drinking (8.3±7.2). The odds of having >6 lost teeth was significantly more frequent among elders with less time in education (OR=2.2, p<0.01) and tobacco smoking (OR=2.8, p<0.01). Conclusion: There are high prevalence and number of tooth loss among elderly Vietnamese. Smoking behaviour and time in education were significantly related to maintaining teeth of the elderly community population.

“…3 In the People's Republic of China, the prevalence of dental caries in the elderly population in different regions ranges from 66.03% to 87.42% in [2009][2010][2011][2012][2013]. 4 The prevalence A nanoemulsion is an emulsion with a droplet size ranging from 1 to 100 nm. Nanoemulsions can be widely used for drug delivery due to their extremely small size, their biocompatibility, their relative stability, and their abilities to solubilize large quantities of hydrophobic compounds, change drug odor, and protect drugs from hydrolysis under physiological conditions.…”

The aim of this study was to prepare a novel nanoemulsion loaded with poorly water-soluble chlorhexidine acetate (CNE) to improve its solubility, and specifically enhance the antimicrobial activity against Streptococcus mutans in vitro and in vivo . In this study, a novel CNE nanoemulsion with an average size of 63.13 nm and zeta potential of −67.13 mV comprising 0.5% CNE, 19.2% Tween 80, 4.8% propylene glycol, and 6% isopropyl myristate was prepared by the phase inversion method. Important characteristics such as the content, size, zeta potential, and pH value of CNE did not change markedly, stored at room temperature for 1 year. Also, compared with chlorhexidine acetate water solution (CHX), the release profile results show that the CNE has visibly delayed releasing effect in both phosphate-buffered saline and artificial saliva solutions ( P <0.005). The minimum inhibitory concentration and minimum bactericidal concentration of CHX for S. mutans (both 0.8 μg/mL) are both two times those of CNE (0.4 μg/mL). Besides, CNE of 0.8 μg/mL exhibited fast-acting bactericidal efficacy against S. mutans , causing 95.07% death within 5 minutes, compared to CHX (73.33%) ( P <0.01). We observed that 5 mg/mL and 2 mg/mL CNE were both superior to CHX, significantly reducing oral S. mutans numbers and reducing the severity of carious lesions in Sprague Dawley rats ( P <0.05), in an in vivo test. CNE treatment at a concentration of 0.2 μg/mL inhibited biofilm formation more effectively than CHX, as indicated by the crystal violet staining method, scanning electron microscopy, and atomic force microscopy. The cell membrane of S. mutans was also severely disrupted by 0.2 μg/mL CNE, as indicated by transmission electron microscopy. These results demonstrated that CNE greatly improved the solubility and antimicrobial activity of this agent against S. mutans both in vitro and in vivo. This novel nanoemulsion is a promising medicine for preventing and curing dental caries.
