“…In our study, we found that DMFT and DMF% of 12-year-old Chinese children presented a V-shaped fluctuant upward trend over the past 20 years, with a decline trend from 1995 to 2000 and a significantly continuous upward trend from 2000 to 2014, and reached the lowest level in 2000. Although compared with the results of European countries and the world [4,20], both DMFT and DMF% were at relative low levels, the rising trend reminds us that the situation of caries in China is still not optimistic and faces great challenges.…”

Background Dental caries have a serious impact on general health and well-being; however, there is a lack of relevant data on the development trends of dental caries in permanent teeth among 12-year-old children in China. We aim to assess long-term trends of dental caries in permanent teeth among 12-year-old children in China and identify the susceptible subgroups based on five consecutive national surveys from 1995 to 2014. Methods A total of 88 972 subjects were extracted from five consecutive national surveys (1995, 2000, 2005, 2010, 2014). Standardized dental examinations were conducted and the oral health status of each subject was recorded. The prevalence of Decayed, Missing and Filled teeth (DMF%), mean Decayed, Missing, Filled teeth score (DMFT) and Caries Filling Ratio (CFR) were used as measurement indicators. Cochran–Armitage trend test was used to evaluate the trends in DMF% and CFR, and multivariate linear regression was used to evaluate the trends in DMFT. Results A V-shaped fluctuating upward trend in DMF% during 1995–2014 was observed (Z = − 13.124, P < 0.001), and the DMF% in 1995–2014 was 21.1%, 15.9%, 16.2%, 21.9% and 24.3%. The trend in DMFT was approximately consistent with DMF% (β = 0.057, P < 0.001), but the downward volatility appeared in 2014. The DMFT in 1995–2014 was 0.38, 0.28, 0.31, 0.66 and 0.54. A continuously fluctuant trend in CFR was observed during past two decades (Z = 1.927, P > 0.05), and the CFR in 1995–2014 was 17.4%, 22.8%, 19.3%, 23.4% and 15.6%. The DMF% and DMFT of rural children had a larger absolute increase than that of urban children during 1995–2014 (DMF%-urban: Z = − 0.242, P > 0.05; DMF%-rural: Z = − 19.036, P < 0.001; DMFT-urban: β = 0.035, P < 0.001, DMFT-rural: β = 0.077, P < 0.001). The DMF% and DMFT in girls were higher than that in boys at each survey year (P < 0.001). CFR of urban children was higher than that of rural children at each survey year (P < 0.001). Conclusions Over the past 20 years, DMFT and DMF% of 12-year-old children in China presented V-shaped fluctuant upward trends, with a decline trend from 1995 to 2000 and an upward trend from 2000 to 2014. CFR had no significant improvement. The rural children and girls are the more vulnerable groups in the development of dental caries and need to pay priority. Our study supports the continuation of policies to improve children’ oral health.

“…A systematic review of dentists' reasons for using or not using more preventive approaches to the treatment of dental caries found that the main reason was economic [ 40 ]. The latest Latvian national epidemiological study shows that the prevalence of dental caries at age 12 is 98.5% [ 13 ]. The same study also finds that only 6.6% of 12-year-olds have sealants [ 13 ].…”

“…Subsequently, on May 13, 2020, it lifted the ban and issued a recommendation to delay elective dental treatments and prefer non-AGPs [ 12 ]. On the other hand, the high prevalence of filled teeth (Care index = 0.83) indicates the traditional invasive caries treatment approach is preferred by Latvian dentists [ 13 ], but there is no specific data on the subject. These national recommendations to restrict or prohibit some dental actions provide an opportunity to evaluate what dentists would do in cases of restricted dental care.…”

Background During the COVID19 pandemic, the Latvian government issued first absolute restrictions (elective treatments prohibited, only emergency care) and later relative restrictions (preference for non-aerosol-generating procedures (AGP) and emergency care) on dental care. This study aims to assess the impact of these restrictions on the decision made by Latvian dentists about caries treatment. Methods A Survey-based cross-sectional study was used. A minimum sample size of 174 dentists was estimated for national representativeness (N = 1524). The questionnaire was developed by experts and sent three times via email to Latvian dentists from July to September 2020 and was also delivered in printed form at two national conferences in September and October 2020. Descriptive statistics were calculated. Results We received 373 completed questionnaires, with a total response rate of 24.5%. Under the recommendation to reduce AGP for the treatment of uncomplicated caries, 10% of the dentists stated that they would stop attending, 54% would only attend emergencies, and 36% would attend as usual. Under prohibition, the percentages are 15%, 74%, and 11%, respectively. Regarding the type of treatment, more than 75% would opt to proceed with selective caries removal for both primary and permanent teeth and 10% for extraction. Conclusion Latvian dentists are willing to treat patients with caries during the pandemic and state that they prefer to use non- or minimally invasive and less aerosol-generating methods for caries treatment.

“…Dental caries is defined as a dynamic and complex process of demineralization and remineralization derived from microbial residual product (lactic acid) deposited on the tooth surface, resulting in overtime, mineral loss, and, possibly, the formation of the cavity [ 9 , 10 ]. Nowadays, dental caries is still considered the most common oral infectious disease affecting several human populations worldwide [ 10 , 11 ]. The complexity of the disease is due to the multiple factors that are associated with the evolution of a bacterial population that goes from a healthy biofilm to a pathological one [ 12 , 13 ].…”

Anti-Adherence and Antimicrobial Activities of Silver Nanoparticles against Serotypes C and K of Streptococcus mutans on Orthodontic Appliances

et al. 2022

Background and Objectives: Streptococcus mutans (S. mutans) is the main microorganism associated with the presence of dental caries and specific serotypes of this bacteria have been related to several systemic diseases limiting general health. In orthodontics, white spot lesions (WSL), represent a great challenge for clinicians due to the great fluctuation of their prevalence and incidence during conventional orthodontic treatments. Although silver nanoparticles (AgNP) have been demonstrated to have great antimicrobial properties in several microorganisms, including S. mutans bacteria, there is no available information about anti adherence and antimicrobial properties of AgNP exposed to two of the most relevant serotypes of S. mutans adhered on orthodontic materials used for conventional therapeutics. The objective of this study was to determine anti-adherence and antimicrobial levels of AgNP against serotypes c and k of S. mutans on conventional orthodontic appliances. Materials and Methods: An AgNP solution was prepared and characterized using dispersion light scattering (DLS) and transmission electron microscopy (TEM). Antimicrobial and anti-adherence activities of AgNP were determined using minimal inhibitory concentrations (MIC) and bacterial adherence testing against serotypes c and k of S. mutans clinically isolated and confirmed by PCR assay. Results: The prepared AgNP had spherical shapes with a good size distribution (29.3 ± 0.7 nm) with negative and well-defined electrical charges (−36.5 ± 5.7 mV). AgNP had good bacterial growth (55.7 ± 19.3 µg/mL for serotype c, and 111.4 ± 38.6 µg/mL for serotype k) and adherence inhibitions for all bacterial strains and orthodontic wires (p < 0.05). The serotype k showed statistically the highest microbial adherence (p < 0.05). The SS wires promoted more bacterial adhesion (149.0 ± 253.6 UFC/mL × 104) than CuNiTi (3.3 ± 6.0 UFC/mL × 104) and NiTi (101.1 ± 108.5 UFC/mL × 104) arches. SEM analysis suggests CuNiTi wires demonstrated better topographical conditions for bacterial adherence while AFM evaluation determined cell wall irregularities in bacterial cells exposed to AgNP. Conclusions: This study suggests the widespread use of AgNP as a potential anti-adherent and antimicrobial agent for the prevention of WSL during conventional orthodontic therapies and, collaterally, other systemic diseases.
