“…It must be pointed out that the filling rates in China (12y: 47.5%; 35/44y: 26.6% and 65/74y: 12.8%) 55 are slightly better than in most of the other emerging countries and that in Sweden -the benchmark for all highly developed countries -nearly 100% of adults up to the age of 60 enjoy full dentition. 56 The pure results of these two differently developed countries are not as far away from each other as one would have expected.…”

“…This result is validated by long-term longitudinal nationally-representative survey data whereby, over the last twenty years, the a) DMFT rate for 12-year-olds remained stable at a very low level, 23 b) the preventive inspection and counselling rate increased to about 40%, c) caries prevalence reduced strongly in 35 to 74-year-olds, d) caries filling rates improved considerably in all age groups, e) tooth loss, on a low level, was concentrated only among seniors and f) the repair rate of dentures rose significantly from 40.1% (2005) to 61.5% (2015). 55 In other words, the oral health status of Chinese people improved substantially and there was a notable increase in the utilisation of dental services. Two lower middle-income countries, India and Vietnam, ranked in second and third place.…”

“…For example, in most of these countries. a) caries prevalence in deciduous teeth is very high (71%-88%), 55,79 b) caries prevalence in the adult population is often rampant (77%-94%), 9,55,79 c) most decayed teeth remain untreated (68%-89%), 9,6,32,36 d) if there is treatment, it is mostly extraction and prescription, 5,9 e) dental service utilisation is rudimentary (10%-31%), 34,[80][81][82] f) oral health literacy is at best 40% (MY) 81 , mostly lower (BR: 28.5%), 83 g) oral health awareness is hardly existent across large parts of the population, h) correct tooth brushing is extremely seldom (ID: 8.5%), 73 i) adequate nationwide dental facilities and workforces are widely lacking 84 everywhere, except in Brazil, where, on average, the dentists/population ratio is sufficiently high, but distribution is very uneven (mostly in urban areas) 85 and j) most people in rural and remote areas cannot afford or are unwilling to pay for dental services.…”

Objective: Investigation into the oral health status of selected emerging countries from different regions of the world, so as to capture a broad spectrum of oral health reality prevailing in fast-growing middle-income countries, the aim being to present helpful steps towards adjusted strategies that improve the dental health of the entire population. Method: Using a composite indicator, the Dental Health Index, the oral health of entire populations is measured and compared with the aid of these quantifiable results. The study relies on existing data, where possible, from national representative surveys. Results: The best performer is the upper middle-income country of China. It is followed by India and Vietnam, two lower middle-income states, which placed second and third, although the two latter populations are largely untouched by professional dental activities. This finding is scientifically challenging to explain and needs further investigation. The relative wealthiest country, Malaysia, ranks in the sixth place while Brazil, with one of the highest dentist per capita ratios in the world, places only eighth, just ahead of the Philippines which ranks last in the study. Conclusion: Over the last decade, the awareness and the willingness shown by all countries to improve their precarious oral care situations resulted in the successful implementation of dental care strategies. However, the main obstacles - the widespread shortage of dentists and the poor oral health awareness among the population, particularly those living in poor and/or rural areas - can only be overcome by development-stage adjusted strategies. The broad use of teledentistry (TD) and priority education and training of mid-level dental professionals could be promising instruments for solving these shortcomings in a manageable period of time and under limited financial resources. To attract additional financial and technical resources and expertise, public/private partnerships should also be encouraged.

Factors of oral sanitation and caries resistance of the teeth: A scientific review

2023

View full text Add to dashboard Cite

This study aimed to analyze social, clinical, and laboratory indicators that contribute to the maintenance of oral sanitation based on current literature. This article analyzed data from foreign and domestic studies indexed in PubMed, CyberLeninka, MEDLINE, Web of Science, Embase, and Scopus. Literature data from the last 15 years were used. Epidemiological data have shown that dental caries affects 90% of the adult populations in the Russian Federation and European countries. The most important role in maintaining oral health care is determined by the complex composition of the microbial community. To ensure caries-free oral cavity from childhood, individual oral hygiene, nature of nutrition, and mineralization of tooth enamel must be emphasized. Caries-specific markers can be saliva proteins. Caries resistance is also caused by differences in the composition of the crystal lattice of enamel apatites and is characterized by an increase in the degree of substitution of the PO4 3group by CO3 2. Maintaining oral hygiene and healthy teeth is influenced by a combination of factors such as the microbial composition of saliva, peculiarities of the metabolism in biofilm, genetic factors, structure of the crystal lattice of enamel apatites, nature of nutrition and peculiarities of individual oral hygiene, local use of fluorides, and educational level.

“…It is a chronic and progressive destructive disease occurring in the hard tissue of teeth under the influence of plaque and bacteria. According to the results of epidemiological survey, the prevalence of dental caries among Chinese adults was 62.7–76.5% in 2015 [ 1 ]. Molars are the most susceptible teeth to dental caries, and the proximal surface of molars is the common site of dental caries [ 2 , 3 ].…”

Background The purpose of this study was to investigate the fracture strength and stress distribution of four ceramic restorations. Methods Forty human mandibular first molars were collected and randomized into four groups after establishing the distal defect: full crown group with 4 mm axial wall height (AWH) (FC4); short AWH crown group with 2 mm AWH (SC2); occlusal veneer group with 0 mm AWH (OV0); occlusal distal veneer group with only the distal surface prepared, and 4 mm AWH (OD4). The teeth were prepared according to the groups and the ceramic restorations were completed using celtra duo ceramic blocks. The ceramic thickness of the occlusal surface is about 1.5 mm and the edge is about 1 mm. The failure load values and fracture modes of each group were detected by mechanical test in vitro. According to the groups to establish three-dimensional finite element analysis (FEA) models, a 600 N loading force was applied vertically using a hemispherical indenter with a diameter of 6 mm. and compare the stress distribution under the condition of different restorations. Results In vitro mechanical tests showed that the failure load values were SC2 (3232.80 ± 708.12 N) > OD4 (2886.90 ± 338.72 N) > VO0 (2133.20 ± 376.15 N) > FC4(1635.40 ± 413.05 N). The failure load values of the short AWH crown and occlusal distal veneer were significantly higher than that of occlusal veneer and full crown (P<0.05). The fracture modes of the full crown and occlusal veneer groups were mainly ceramic fractures and some were restorable tooth fractures. The short AWH crown and occlusal distal veneer groups presented with three fracture modes, the proportion of non-restorable tooth fracture was higher. The results of FEA show that under the spherical loading condition, the stress of ceramic was concentrated in the contact area of the loading head, the maximum von Mises stress values were FC4 (356.2 MPa) > VO0 (214.3 MPa) > OD4 (197.9 MPa) > SC2 (163.1 MPa). The stress of enamel was concentrated in the area where the remaining enamel was thinner, the maximum von Mises stress values was OD4 (246.2 MPa) ≈ FC4 (212.4 MPa) > VO0 (61.8 MPa) ≈ SC2 (45.81 MPa). The stress of dentin is concentrated in the root furcation and the upper third region of the root. However, stress concentration was observed at the tooth cervix in the full crown. Conclusion Under certain conditions, the occlusal distal veneer shows better performance than the full crown.
