Introduction: Several studies have reported a high prevalence of dental caries among the people with intellectual disabilities. In order to identify the sociodemographic, clinical and behavioral factors associated with it, we conducted a study in specialized centers welcoming subjects with intellectual disabilities in Ouagadougou (Burkina Faso). Objectives: The objective of this study was to identify the factors associated with it among intellectually disabled in the specialized centers of Ouagadougou. Methods: The study was cross-sectional analytical. The survey took place between November 2020 and January 2021 among people with intellectual disabilities in reception centers receiving a grant from the Ministry of Women, National Solidarity, Family and Humanitarian Action. Data collection was done with a questionnaire adapted from the World Health Organization (WHO) and dental caries was recorded according to WHO criteria in decayed, missing or filled teeth generating a DMF index. Logistic regression was used to identify factors associated with the presence of dental caries. Results: A total of 193 participants were included in the study with an average age of 12.4 years ± 7.9. The overall prevalence of caries measured with the DMF index was 58.6% 95% CI [51.2 - 65.8]. It was significantly associated with female gender (OR = 4.2;95% CI [1.4 - 12.5], p = 0,01), the clinical form of mental illness (epilepsy OR = 3.8 95%;CI [1.2 - 12.7], p = 0,02, trisomy OR = 5.0;95% CI [1.1 - 22.9], p = 0,03, motor autonomy OR = 0.2 95%;CI [0.1 - 0.7], p = 0,01) and at use of toothpaste OR = 9.33;95% CI [1.05 - 82.7], p = 0,04. Conclusion: dental caries remains a very present pathology in most people living with an intellectual disability. Also, it is necessary to put in place prevention strategies to reduce its prevalence and improve access to oral care for these people.

作者： Ya-Ling Liu Marcelle Nascimento Robert A Burne Depa rtment of Oral Biology College of Dent stry University of Florida Gainesville USA Department of Restorative dental Sciences Division of Operative Dentistry College of Dentistry University of Florida Gainesville USA

Alkali production by oral bacteria is believed to have a major impact on oral microbial ecology and to be inibitory to the initiation and progression of dental caries. A substantial body of evidence is beginning to accumulate that indicates the modulation of the alkalinogenic potential of dental biofilms may be a promising strategy for caries control. This brief review highlights recent progress toward understanding molecular genetic and physiologic aspects of important alkali-generating pathways in oral bacteria, and the role of alkali production in the ecology of dental biofilms in health and disease.

Background Decayed teeth are harmful to children＇s growth and development and can severely jeopardize their health. This study was set out to investigate and analyze the prevalence of dental caries in preschool children in Shanghe County in Shandong Province, China, and provide new insights into potential prevention and treatment strategies. Methods Based on the random sampling method, we performed dental examinations of children aged 2 to 6 years in kindergartens of Shanghe County. The prevalence of caries, the average number of decayed teeth per capita as well as the constituent rates of decayed, missing and filled teeth were determined retrospectively. SPSS software was used for data analysis. Results dental caries were found in 1088 out of 2052 children from 56 kindergartens. The total number of decayed teeth was 4487 with a prevalence of 53.02%. The average number of decayed teeth per capita was 2.187, and the filling rate was 0.29%. There was no statistical difference in the prevalence of caries between boys and girls though there were significant differences between different age groups. The prevalence of decayed teeth as well as the mean number of decayed teeth infected per capita increased with age. In addition, urban children had a higher prevalence than those from rural areas （P 〈0.01）. Conclusions The prevalence of decayed caries among kindergarten children in Shanghe County was high, suggesting that more emphasis should be put on improving oral health education with priority given to prevention. Further efforts should be made to increase the decayed caries filling rate.

Relationships between daily total fluoride intake and dental fluorosis and dental caries

引用

Journal of Nanjing Medical University 2009年第1期23卷 33-39页

作者： Quanyong Xiang Minghao Zhou Ming Wu Xinya Zhou Li Lin Jiuning Huan Youxing Liang Jiangsu Province Center for Disease Control and Prevention Nanjing 210009 China Suqian Center for Disease Control and Prevention Suqian 223800 China Department of Occupational Health School of Public Health Fudan University Shanghai 200032 China

Objective： To explore the relationships between the daily total intake of fluoride, dental fluorosis and dental caries. Methods： An epidemiological method was used to investigate the daily total intake of fluoride, dental fluorosis, and dental caries among 236 and 290 children aged 8-13 years in a severe endemic area and in a non-fluorosis control area, respectively. The children were divided into eight subgroups according to each child＇ s estimated daily total intake of fluoride. The prevalence of dental fluorosis and dental caries in each group was calculated. Results： As expected, elevated levels of fluoride intake were significantly associated with a higher prevalence of dental fluorosis and an increasing amount of more severe defect dental fluorosis. When the daily total F intake was 2.78 mg/child/day, the prevalence of dental fluorosis was nearly 100%, with the prevalence of defect dental fluorosis increasing with increasing fluoride intake. There was also a significant negative（inverse） dose-response relationship between the daily total intake of fluoride and the overall prevalence of dental caries, the prevalence of which decreased when the daily total intake of fluoride increased up to 3.32 mg/child/day. However, at higher levels of daily total intake of fluoride the prevalence of dental caries increased, giving rise to a U-shaped dose-response relationship curve. Conclusion： It is important to monitor total fluoride exposure and protect children from excessive fluoride intake, especially during the years of tooth development.
