COVID-19: the impact on oral health care.

The COVID-19 pandemic has highlighted the economic, social, and oral care health inequities in societies, especially in the developing world. Severe restrictions have been imposed on dental practices, limiting prophylactic and routine oral care health, allowing treatment only for emergencies. Since dental care includes procedures that generate aerosols, the risk of infection for dental personnel has increased significantly.

Relationship of hyposalivation and xerostomia in Mexican elderly with socioeconomic, sociodemographic and dental factors.

We determined the prevalence of hyposalivation and xerostomia in older Mexicans (≥60 years), and its relationship with diverse factors. A cross-sectional study was realized in elderly subjects from Pachuca, Mexico. Chewing-stimulated saliva was collected under standardized conditions and salivary flow was measured; subjects were considered to have hyposalivation if their stimulated salivary flow was less than 0.

Tooth-Loss Experience and Associated Variables among Adult Mexicans 60 Years and Older.

Objective: This study was conducted to determine the experience of tooth loss, as well as its associated variables, in a sample of adult Mexicans, aged 60 years and older.

Materials And Methods: This cross-sectional study was part of a larger project to measure diverse oral health indicators in a convenience sample: it included 139 adult Mexican seniors (69.1% of whom were women), ages 60 years and older, either living in long-term care facilities or living independently and participating in adult day care services.

Dental fluorosis: concentration of fluoride in drinking water and consumption of bottled beverages in school children.

Objective: The purpose of the study was to identify dental fluorosis prevalence and to analyze its association with tap water fluoride concentration and beverage consumption in school children from the city of Oaxaca, who were receiving fluoridated salt.

Study Design: A cross-sectional study was performed on elementary public school children. Dean's Index was applied to assess dental fluorosis.

The relationship between body mass index and body fat percentage and periodontal status in Mexican adolescents.

Objective: To assess the association between obesity indicators and the periodontal status of high school students.

Materials And Methods: High school students (15-year-olds) in Mexico City participated in the survey (n = 257). International Obesity Task Force cut-off values (ISO-BMI) were applied to identify overweight and obesity.

Fluorosis and dental caries in Mexican schoolchildren residing in areas with different water fluoride concentrations and receiving fluoridated salt.

Objective: To explore the association between fluoride in drinking water and the prevalence and severity of fluorosis and dental caries in children living in communities receiving fluoridated salt.

Material And Methods: Participants were schoolchildren (n = 457) living in two rural areas of the State of Morelos, Mexico, where the water fluoride concentration was 0.70 or 1.

Osteoporosis, the risk of vertebral fracture, and periodontal disease in an elderly group in Mexico City.

Objectives: The aims of this study were to identify the possible association of osteoporosis, fracture risk and periodontitis, and consider the role of pharmacological treatment of osteoporosis and the periodontal condition.

Methods: Patients aged 60 and older from the Mexican National Medical Science and Nutrition Institute Salvador Zubirán participated in the study. DXA was used to assess osteoporosis and risk of vertebral fracture.

In vitro quantitative microhardness assessment of enamel with early salivary pellicles after exposure to an eroding cola drink.

To assess the erosive effect of a cola drink on enamel incorporating early salivary pellicles, 72 groups of human enamel slabs were immersed in fresh cola, with groups differing in that slabs were (1) incubated in whole or in clarified saliva, (2) under three regimes of frequency intake (1, 5 and 10 times/day); (3) immersed with or without agitation, and (4) the pellicle was incubated for 20 min, 6 or 24 h. Quantitative assessments were done over an 8-day interval using surface microhardness testing. Results for primary enamel showed a sharp decrease from baseline (344.

[Prevalence of dental caries, gingivitis and periodontal disease in pregnant diabetic women].

Objective: To determine the difference in the prevalence of dental caries, gingivitis, and periodontal disease among non-diabetic, type-II diabetic and pregnant diabetic women.

Material And Methods: In the period from June 1993 to January 1994, a cross-sectional study was carried out at the Instituto Nacional de Perinatología among 160 pregnant women; eighty non-diabetic women were included in the control group, while 40 type-II diabetic and 40 gestational diabetic women conformed the study group. In each patient the following variables were recorded: age, week of pregnancy, the Simplified Oral Hygiene Index, the Decayed, Missing and Filled Teeth Index, the Gingival Index, and the Extent and Severity Index.
