Dental caries in Mexican schoolchildren : a comparison of 1988?1989 and 1998?2001 surveys
2012
Objectives: To compare two surveys across seven states for the prevalence of dental caries among Mexican schoolchildren. Study Design: Analysis of two cross-sectional surveys: Schoolchildren from 6 to 10 years of age were examined in the 1988–1989 survey and 6- to 10-year-old and 12-year-old students were included in the 1998–2001 survey. The baseline data of seven states were available for analysis. Representative probability samples were conducted statewide in both surveys. The World Health Organization (WHO) method was used to obtain the dental caries index (dmft, DMFT). At present, additional and more recent epidemiological data representative statewide in Mexico are unavailable. Result…
The impact of head and neck radiotherapy on the dentine-enamel junction: a systematic review
2019
Background Radiotherapy is widely used in contemporary head and neck cancer treatment protocols. The ability of head and neck radiotherapy (HNRT) to cause direct radiogenic destruction to the teeth is one of the most controversial topics in the field of oral oncology. Therefore, this systematic review aimed to investigate ionising radiation as an independent factor for physical and chemical changes on the dentine-enamel junction (DEJ), a pivotal dental topography for the onset and progression of radiation-related caries (RRC) and enamel delamination. Material and Methods Systematic searches were conducted on three databases: Scopus, MEDLINE (Via PubMed) and Embase (Elsevier). Laboratory stu…
Determinación de Streptococcus Mutans y Streptococcus Sobrinus, mediante pcr cuantitativa a tiempo real, y su relación con la caries dental en escola…
2013
La caries dental presenta una etiología multifactorial, los factores ambientales, los hábitos de alimentación, higiene bucal y la susceptibilidad genética individual, juegan un papel importante en el desarrollo de esta enfermedad (1). Los Streptococcus mutans y Streptococcus sobrinus están fuertemente implicados en la aparición de la caries dental en humanos. Numerosos estudios han demostrado que la asociación de S. mutans y S. sobrinus conlleva niveles más altos de caries (2-4) y varios estudios han encontrado que la prevalencia deS. sobrinus está fuertemente asociada con mayor actividad de caries que la delS. mutans (5-6). Se considera que la determinación de estas dos especies en la infa…
Spatial-temporal analysis of hospitalizations with death caused by oral cancer in Brazil and its correlation with the expansion of healthcare coverag…
2022
Oral cancer (OC) is a growing public health problem worldwide. In Brazil, the National Oral Health Policy, implemented in 2004, expanded access to oral health services and prioritized OC care. However, it is not known whether this expansion resulted in a reduction in hospital admissions with death. This study aimed to analyze the proportion of hospital admissions who progressed to death due to OC in Brazil from 2007 to 2019 and its correlation with the coverage of health services. This study is an ecological, longitudinal, and analytical study of hospital admissions with death due to OC recorded in the Brazilian Hospital Information System. The following analyses were performed: descriptive…
