Prevalence and severity of dental caries using ICDAS in predicting treatment needs in Mexican school-age children.

Evaluate the prevalence and severity of caries in permanent teeth and their association with the treatment needs of 8-12-year-old Mexican schoolchildren. The cross-sectional study was conducted on 1139 8-12-year-old schoolchildren attending two public primary schools in State of Mexico. The study used the International Caries Detection and Assessment System (ICDAS) to examine the prevalence of caries and identify treatment needs in schoolchildren.

Relationship Between Low Education and Poor Periodontal Status among Mexican Adults Aged ≥50 Years.

Purpose: To examine the association between educational level and the presence of periodontal disease in adults ages ≥ 50 years in Mexico.

Materials And Methods: A cross-sectional study was conducted on 2098 Mexican adults, using data from the annual reports of the Epidemiological Monitoring System for Oral Pathologies from 2019-2022. Data were collected on sociodemographic characteristics such as gender, age, educational level, oral hygiene, and diabetes.

Theoretical method for a radiopacifier proportion calculation in MTA type cements.

This article deals with the problem of determining the proportion by weight of radiopacifying material needed to add to a cement clinker of mineral trioxide aggregated (CE) to comply with ISO 6876/2001 and ANSI-ADA 57 regulations for radiopacity. With this aim, CE was synthesized and mixed experimentally with 5, 10, 15, and 20 wt% of ZrO as radiopacifying material. Radiographic images were taken so that radiographic density was obtained and related to the mmAl scale by using an aluminum step wedge.

Association Between Self-Reported Health and Education with Past-year Dental Visits among Older Mexican Adults: Results of the Mexican Health and Aging Study 2018.

Purpose: To explore the relationship between of self-reported health (SRH) and educational attainment with pastyear dental visits in older adults in México.

Materials And Methods: For this cross-sectional study, data were derived from the Mexican Health and Aging Study 2018 (MHAS-2018), which used a nationally-representative sample of older adults (50 years or older) in Mexico (n = 14,085). Variables taken from the MHAS questionnaire included residence (rural/urban), years of education, SRH, multimorbidity, pain severity, and past-year dental visits.

Correlation between dental enamel chemical composition and bracket debonding, comparing adhesive systems through a scanning electron microscope.

Literature reports indicate that during bracket removal there can be enamel damage. We compare the shear bond strength (SBS) and tooth enamel loss of four adhesive systems and identify the Ca/P ratio. Then a total of 20 premolars were divided into four groups of five each.

Evaluation of enamel loss by scanning electron microscopy after debonding brackets place with four different adhesives.

The clinically adequate shear bond strengths (SBS) should be from 2.8 to 10 MPa. The aim of this research is to observe tooth enamel loss through a scanning electron microscope (SEM) during the debonding of braces of four adhesive systems.

Comparative study of dental enamel loss after debonding braces by analytical scanning electron microscopy (SEM).

Clinical procedures when shear forces are applied to brackets suggest adhesion forces between 2.8 and 10.0 MPa as appropriate.
