Caries status and related factors among 12-year-old children in Yangpu District， Shanghai / 上海预防医学

ObjectiveTo investigate the prevalence and risk factors of dental caries and its related influencing factors in 12-year-old children in Yangpu District， Shanghai， and to provide relevant data support for the formulation of oral health policies and measures for children. MethodsIn 2021， 839 12-year-old children were randomly selected from five ordinary junior high schools in Yangpu District. The investigation included an oral health examination and a questionnaire survey on factors related to dental caries. Logistic regression analysis was used to analyze the influencing factors of dental caries. ResultsAmong the 839 participants， data from 830 were included. Among them， 426 were male （51.3%） and 404 were female （48.7%）. Of the 830 children， 203 had dental caries， resulting in a caries prevalence of 24.46%， a caries supplemental filling ratio of 32.6%， and a DMFT of 0.63. Multivariate logistic regression analysis revealed that a mother’s education level of college or above （OR=0.849，95% CI： 0.732‒0.984）， brushing teeth twice a day （OR=0.827，95%CI： 0.703‒0.973）， and the caregiver brushing teeth twice a day （OR=0.843， 95%CI： 0.726‒0.983） were effective factors in reducing the caries rate. Factors associated with childhood dental caries included consuming sweets ≥1 time per day （OR=1.397，95%CI： 1.197‒1.342） and female gender （OR=1.482，95%CI： 1.347‒1.671）. ConclusionThe prevalence of dental caries among 12-year-old children in Yangpu District is 24.46%. Gender， maternal education， the frequency of children's toothbrushing， the frequency of sweet consumption， and the caregiver’s toothbrushing frequency are the main factors affecting the prevalence of dental caries in children.

Effect assessment of caries management by risk assessment in children in the Minhang district of Shanghai / 口腔疾病防治

Objective@#To assess the effect of caries management based on risk assessment in children and to provide the basis for the government to develop strategies to prevent and treat oral diseases.@*Methods@# From March 2018 to March 2019, 512 3-year-old children and 502 6-year-old children were selected by cluster sampling from kindergartens and primary schools, respectively, in the Minhang district of Shanghai, and oral examinations and questionnaires were carried out to assess baseline status. Then, the children were divided into 3 groups, including low-, middle- and high-risk groups, according to caries risk assessment. In each caries risk group, the children were randomly divided into an experimental group and a control group. The experimental groups were managed by risk assessment, and the control groups were provided basic oral public health services by the Shanghai government. The effect of caries prevention was evaluated 12 months later.@*Results@#Among the children with a high risk of caries, the incidence of caries was 51.22% in the 3-year-old control group, 34.17% in the experimental group, 51.27% in the 6-year-old control group and 33.15% in the experimental group, with statistical significance (P < 0.05). Among the children with a middle risk of caries, the incidence of caries was 38.71% in the 3-year-old control group and 7.32% in the experimental group, with statistical significance (P < 0.05). However, there was no significant difference in caries incidence between the control group and the experimental group for the children with low risk in the 3-year-old or 6-year-old groups and middle risk caries risk in the 6-year-old group. Both 3-year-old and 6-year-old children in the experimental group had a lower risk of caries than those in the observation group in 2019.@*Conclusion@#The caries prevention effect is remarkable in high-risk children, and caries management by risk assessment is probably recommended for children with high caries risk.

The prevalence of dental caries in urban areas is lower than that in rural areas--analysis of changes in the epidemiological characteristics of caries in urban and rural areas / 口腔疾病防治

@#As one of the most common chronic diseases of the oral cavity, caries gradually accumulate over the lifetime and affect approximately 80% of the world population. The epidemiological characteristics of the disease are specific in terms of regional distribution, temporal distribution and population distribution. Caries prevalence and mean decayed, missing and filled permanent teeth (mean DMFT) scores are the most commonly used indexes in oral epidemiology. Caries prevalence is used to describe the frequency of caries over a certain period of time. In addition, DMFT scores reflect the severity of caries in the population. The caries prevalence and the severity of caries are assessed as part of a dynamic process. In developing countries, caries prevalence is higher among urban populations than among rural populations. Currently, the epidemic characteristics of caries in urban and rural areas are changing, and the caries prevalence of urban residents is lower than that of rural residents. This article is a chronological review of the Oral Health Epidemiological Surveys of China from 1983 to 2015, the Preventive Dentistry study and other related studies. It is concluded that the epidemic characteristics of caries in urban and rural areas in China have changed from a higher caries prevalence in urban areas compared to that in rural areas to a lower caries prevalence in urban areas compared to that in rural areas. Several factors, such as the dynamic development of differences in dietary habits, economic levels and access to oral medical resources of urban and rural residents might have led to changes in caries prevalence in urban and rural areas. The caries prevalence of rural residents has increased greatly, which indicates that the caries prevention efforts of the relevant departments should be focused more on rural areas in the future.

The assesment of dental caries status among Students of school of dentistry, mnums / Шинэ санаа Шинэ нээлт

@#The most common oral disease is the dental caries, which is chronic transmissible, losing of hard tissue of teeth, and is very widespread in the world. The annual report of oral health survey of World Health Organization shows that 60-90% of population of developing countries was affected by dental caries. In the press review, the prevalence of dental caries and mean DMFt score among 18 years old were 74.4% and 4.04 in Mexico, 2009; 87.4% and 3.59 in Australia, 2003; and 88.9% and 7.15 in Japan, 1999. In Mongolia, the prevalence of dental caries and mean DMFt score among military students in 1987 were 83.3% and 3.7. There is a few studies among students of School of dentistry. Study population consisted of 115 students, who studied from 3rd to 5th course of School of Dentistry, Mongolian National University of Medical Sciences. Study was done by cross sectional study design from November to December, 2017. We checked up dental status of all students according to recommendation by WHO, 2013. The study was approved by the Medical Research Ethics Committee of the Mongolian National University of Medical Sciences and informed consent was obtained from all students (2017/3-04). The prevalence of dental caries among all students was 100% and mean dental caries score was 8.3±0.3 DMF/t, 3.7±0.3 D/t, 3.8±0.3 F/t, 0.8±0.1 M/t. When we assessed mean DMF/t score by student’s course, it was 8.5±0.5 among 3rd year students, 8.6±0.7 among 4th year and 7.9±0.5 among 5th year (p>0.05). Mean decayed teeth among 3rd, 4th, 5th course students were 4.5±0.5, 4.1±0.6 and 2.8±0.4, respectively (p<0.05). Mean filled teeth was 3.4±0.5, 3.5±0.6, 4.4±0.4 (p>0.05) and missed teeth was 0.7±0.2, 1.0±0.3, 0.7±0.2 (p>0.05) among students respectively above courses. All students, who participated in our study had dental caries and observed declining the number of decayed teeth during the study and the number of filled teeth was increasing.

A comparative study on early childhood caries detection by using international caries detection and assessment system-Ⅱ and WHO criteria / 中华口腔医学杂志

Objective@#To investigate and compare the sensitivities of early childhood caries detection by using international caries detection and assessment system (ICDAS)-Ⅱ and WHO criteria.@*Methods@#A total of 449 3-year-old children from four day care kindergartens in Beijing were enrolled in this study. Both ICDAS-Ⅱ and WHO criteria were used to assess the prevalence of caries in the given subjects. The decayed, missing, and filled teeth (dmft) index scores were calculated. In ICDAS-Ⅱ system, four cut-off points (D1, D2, D3 and D4) were employed to differentiate sound and decayed teeth: D1 (score 0 as sound, scores 1-6 as caries); D2 (0-1 sound, 2-6 caries); D3 (0-2 sound, 3-6 caries) and D4 (0-3 sound, 4-6 caries). SPSS software was used to analyze the data to decide the significance of differences.@*Results@#The caries prevalence using ICDAS-Ⅱ were 76.6% (344/449), 71.3% (320/449), 52.8% (237/449) and 46.1% (207/449) for D1 to D4, respectively; the corresponding mean dmft scores were 4.95±4.85, 4.41±4.77, 2.54±3.69 and 1.97±3.10. The sites with highest caries prevalence were occlusal surface of mandibular molars in groups of D1 and D2 and proximal surface of maxillary anterior teeth in groups D3 and D4. In contrast, the caries prevalence was 48.8% (219/449) and the mean dmft was 2.27±3.54 when using WHO criteria, significantly lower than the detection rates by using ICDAS-Ⅱ (D1-D2) (P=0.00). This suggested that ICDAS-Ⅱ system was a more sensitive method in detecting early childhood caries.@*Conclusions@#ICDAS-Ⅱ system might be superior in detection of incipient caries and be of specific value in prevention of early childhood caries.

Squamous cell carcinoma of the oral cavity and oropharynx in patients aged 18–45 years: A case–control study to evaluate the risk factors with emphasis on stress, diet, oral hygiene, and family history.

BACKGROUND: Increasing incidence of squamous cell carcinoma (SCC) of the oral cavity and oropharynx is reported in young adults. However, there is a paucity regarding etiology and risk factors. AIM: To evaluate the exposure potential carcinogenic factors among a sample aged 45 years and younger, diagnosed with SCC of the oral cavity and oropharynx. METHODOLOGY: Eighty‑five case samples aged 18–45 years, diagnosed with SCC of the oral cavity and oropharynx were compared with 85 controls who had never had cancer, matched for age and sex. This study was conducted by questionnaire‑based interviews. Questionnaire contained items about exposure to the following risk factors: Caries prevalence, oral hygiene status, dental trauma, dental visit, stress, family history of cancer, environmental exposure to potential carcinogens, diet, body mass index (BMI), habits such as smoking, tobacco chewing, betel quid/pan, or supari. STATISTICAL ANALYSIS: Odds ratios (ORs) of oral and pharyngeal cancer and the corresponding 95% confidence intervals were estimated using multiple logistic regression models. P < 0.05 was considered statistically significant. RESULTS: Elevated OR was seen in young adults who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid for 11–20 years. CONCLUSIONS: An increased risk of oral and pharyngeal cancer was seen in cases who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid.

Epidemiological investigation of dental fluorosis and dental caries in children from binhai new area / 天津医药

Objective To investigate the incidence of dental fluorosis and pit caries in school-age children from binhai new area of Tianjin, and to discuss the relationship between dental fluorosis and pit caries, providing the guidance for the prevention and treatment of them. Methods Referring to WHO’s“Oral Health Surveys Basic Methods”(Fourth Edition) and protocols of the third national oral epidemiology investigation, 3 778 children aged 7 to 9 year-old with similar levels of education were investigated for their dental fluorosis and fissure caries using the cross sectional survey method. Results The data showed that the incidence of dental fluorosis was less than 10%in the samples, and the community fluorosis index (CFI) was 0.075. The caries prevalence rate and mean decayed missing filled tooth (DMFT) of first permanent molars were 15.57%and 0.46 in male students, and those were 17.41%and 0.58 in female students. There were no significant differences in the caries prevalence rate and DMFT of first molar between male and female children (χ2=2.345, P>0.05). There were statistically significant differences in the caries rate and DMFT between different age groups (χ2=172.576, P<0.05), and both increased with age. Conclusion After years of defluoridation project in Tianjin, the detection rate and index of dental fluorosis in children have showed a downward trend. The caries prevalence rate may be related to the eruption rate of the first permanent molar.

Objetivo: Dada la limitada información epidemiológica en Chile sobre las patologías orales más prevalentes y el efecto de los programas de salud instaurados, el objetivo de este estudio fue evaluar los cambios en la prevalencia de caries y gingivitis en una población de 6 y 12 años de la VI Región, entre los años 2000 y 2010. Sujetos y Métodos: 143 sujetos de 6 y 12 años atendidos en el CESFAM de Peralillo fueron examinados clínicamente para detectar caries y diagnosticar gingivitis. Las fichas clínicas de 134 niños de las mismas edades y procedencia atendidos el año 2000 fueron analizadas para comparar los indicadores. Se obtuvo el índice de caries mediante el COPD y el ceod, además del diagnóstico gingival mediante parámetros clínicos. Los resultados de ambos años fueron comparados estadísticamente y las diferencias consideradas significativas si p<0.05. Resultados: La prevalencia de caries a los 6 años disminuyó de 89 por ciento a 65 por ciento, pero sólo el COPD mostró una reducción estadísticamente significativa de 0.93 a 0.086. A los 12 años, ni la prevalencia de caries ni el índice COPD mostraron un cambio significativo. La prevalencia de gingivitis disminuyó significativamente en ambos segmentos de edad en los 10 años de evaluación. Conclusiones: Pese a verificarse una leve disminución, la prevalencia de caries en Peralillo continua siendo muy alta y no ha variado sustancialmente en 10 años. Se sugieren más estudios similares para evaluar la eficacia de los programas en curso.

Aim: Given the limited epidemiological information in Chile on the most common oral diseases and the effectiveness of the existent programs, the aim of this study was to evaluate the changes in caries and gingivitis prevalence in a 6 and 12 year-old children from the VI Region, between the years 2000 and 2010. Subjects and Methods: 143 6 and 12 year-old children treated at the CESFAM of Peralillo were clinically examined to detect and diagnose caries and gingivitis. Clinical records of 134 same ages children treated at the same service in the year 2000 were analyzed to compare the indexes. Caries index was obtained by DMFT and dmft and gingivitis was assessed by clinical parameters. Results obtained both years were compared and considered significant if p<0.05. Results: Caries prevalence decreased in the group of 6 year-olds from 89 percent to 65 percent, but only DMFT showed a significant reduction from 0.93 to 0.086. In the 12 year-old children, neither caries prevalence nor DMFT showed significant changes within the 10-year period. Conclusions: In spite of a slight decrease, caries prevalence in Peralillo continues to be very high and it has not substantially changed in 10 years. Further similar studies are suggested to assess the efficacy of the current programs in use.

Determinar la prevalencia de caries que presentan los Primeros Molares Permanentes (PMP) en niños chilenos de 6 años. Se realizó un estudio descriptivo, de corte transversal del estado de los PMP, en niños de seis años que asistieron al Hospital de Calbuco, X Región, Chile, durante el año 2008. Un operador calibrado examinó 166 niños de nivel socio-económico similar. La presencia de caries se estableció en base a los criterios propuestos por la OMS en el Oral Health Survey Basic Methods, para estudios epidemiológicos. El 65% (434/664) de los PMP se encontraban erupcionados, 47 (7%) semi- erupcionados y el 28% (183/664) aún no erupcionaban. De los PMP erupcionados y semierupcionados, el 69,02% (332/481) presenta caries. Al comparar la prevalencia de caries entre los PMP superiores y los inferiores se encontró una diferencia estadísticamente significativa (p<0,001). En los PMP superiores la mayor prevalencia de caries fue en la superficie oclusal, con un 56% (131/235), y en los PMP inferiores la superficie más afectadas fue la vestibular con un 68% (168/246).Conclusión: Los resultados demuestran la necesidad de incorporar estrategias de educativas y preventivas antes de la erupción del PMP

To determinate the prevalence of caries in first permanent molar (FPM) in six year-old Chilean children.Method: A Cross-sectional study was performed to state of FPM in six year-old children who attended in Calbuco Hospital, during 2008. A investigator previously calibrated to examined 166 Children belonging to the same socio-economic level. Caries diagnoses were carried out using standardized methods World Health Organization. 65% (434/664) of FPM were erupted and 47 (7%) partially erupted and 28% (183/664) were not erupted yet. From FPM erupted and partially erupted 69,02% (332/481) have caries. When comparing the prevalence of caries between upper and lower PFM, a significant statistical association was found (p<0,001). In the upper FPM the mayor prevalence of caries was found in the occlusal with 56% (131/235), in the lower FPM the most affected surface was the vestibular with a 68% (168/246). The results show the necessity of incorporating educative and preventive strategies before the eruption of FPM

La prevalencia de niños con al menos una superficie afectada por lesión no cavitada fue del 73.4%. La prevalencia de caries dental fue significativamente mayor en la IPS La Playa (70.2%) que en Itagüí (62.8%). Conclusión: El uso de sistemas de diagnóstico de caries dental que incluyen la lesión no cavitada es de gran importancia, el elevado porcentaje de caries dental encontrado en este grupo de la población indica la necesidad de un diagnóstico precoz y al mismo tiempo de desarrollar actividades terapéuticas y preventivas específicas y oportunas para este grupo de edad.

Introduction and Objective: Dental caries diagnosis during early childhood should be a priorityin all health systems. The purpose of this study was to describe the initial dental caries situation in children with complete deciduous teeth, both genders, with lower and middle lower social-economic level from an urban area in Medellín. Materials and Methods: A randomly selected sample of 447children between 2 and 4 years old was calculated; the sample was taken from the Susalud database, with 95% reliability, power of 80% and an error of 5%. A clinical test was performed by 3 calibrated examiners according to the International Dental Caries Detection and Assessment System (ICDAS)(Kappa 0.73 – 0.85). A WHO periodontal probe (11.5) was used for caries detection. Results: Treated and untreated dental caries prevalence of children was 74.7% with a specific mean of 9.7 ± 9.3 (SD), affected surfaces, prevalence of children having surfaces affected by non- treated dental decay was 74.9% while the dmf-s mean was 7.6 ± 7.7 (SD). 73.4% of children had at least one non-cavitated affected surface. Dental caries prevalence at “La Playa” Dental Clinic (70.2%) was higher than the“Itagúi” Dental Clinic (62.8%) with a significant statistical difference (p value = 0.01 chi). The dmf-smean according to Dental Clinic was 0.8 ± 2.7 (SD) in Itagui and 1.5 ± 3.9 at La Playa. Conclusions: The use of diagnostic systems that include non-cavited lesions is very important, the high percentage of decay at this age indicates the early presence of this illness, thus the importance of an early diagnosisand at the same time the implementation of specific treatment and prevention.

Prevalence of Caries and Edentulous in 65-74 Years Old Adults in Ulanbator / Монголын Анагаах Ухаан

Background: Many industrialized countries are witnessing a demographic evolution characterized by the aging of their population. For people over aged 65 year, the prevalence of tooth decay, gum disease and oral cancer is higher than for the general population and higher rates for edentulism (missing teeth), few sound teeth and more filled and decayed teeth than the general population. Risk factors for oral diseases include unhealthy diet, tobacco use, harmful alcohol use, and poor oral hygiene. There is no research work concerning the oral health status of the older population aged 65-74 years old. These age group is selected because they were the adult population groups recommended by the WHO for oral health survey. The purpose of this study was to determine prevalence of caries and edentulous of 65-74 years old and living in the Ulanbator. Methods: An epidemiological survey of 365 older people aged 65-74 was carried out in 2008. It followed the WHO methodology to assessing the oral health status and caries lesions, fi llings, missing teeth were recorded using the WHO criteria. Result: The mean age was 68.70.16. The DMFT index at 65-74 years for the Ulanbator population was 19.50.89 DMFT. Caries prevalence was 52.7% among older people. 4.1% were fully dentate, 21.6% were edentulous, 74.2% were partial edentulism, respectively. Mean number of decayed teeth (DT index) was 3.4, fi lling teeth (FT index) was 2.3, missing teeth (MT index) was 18.0. Conclusion: We carried out this study 365 older people aged 65-74. This preliminary study provide evidence in the direction of building the base of knowledge on prevalence of caries and edentulous elderly person in Ulanbator. The planning and implementation of any strategy for oral health status improvement is crucial alongside the countrys infrastructure development.
