Genetic variation in the glucosyltransferase-B gene of Streptococcus mutans and its relationship with caries experience in children from Córdoba, Argentina, and with strains from other countries.

Background: Caries is a worldwide distributed oral disease of multifactorial nature, with Streptococcus mutans being the most commonly isolated bacterial agent. The glycosyltransferases of this bacterium would play an essential role in the aetiology and pathogenesis of caries.

Aim: We explored how the glucosyltransferase-B (gtf-B) gene variability of S.

Oral health of youth housed in socio-educational centers of the Juvenile Penal Area of the Province of Córdoba, Argentina.

The purpose of this research was to analyze the oral health status of youth housed in socio-educational centers of the Juvenile Penal Area of the Province of Córdoba, Argentina of corrections by considering clinical evaluation and the main sociodemographic data. Socio-demographics, healthy and unhealthy habits of self-care, and dental clinical profile were assessed for this purpose. An exploratory cross-sectional study was carried out on 70 14- to 18-year-olds who had been institutionalized for at least six months.

[Caries experience and quality of life of confined teenagers].

Objective: To evaluate the impact of caries on the quality of life of teenagers confined in the Correctional Center of Córdoba, Argentina.

Method: A clinical examination was conducted to 70 teenagers in order to determine DMFT and the necessary treatment. The Oral Health Impact Profile (OHIP-49) was used.

Oral health in drug addict adolescents and non psychoactive substance users.

The purpose of this study was to compare oral health between adolescents who are recovering drug addicts and adolescents who report not having used psychoactive substances. A retrospective observational Case-Control study was conducted on 60 subjects per group, aged 15 to 25 years, paired according to sex, age and educational vulnerability. Dental and sialochemical examinations were used to determine oral health/disease/care indicators.

Initial acquisition and genetic identity of Streptococcus mutans of mother-child Pairs.

Purpose: This study's purpose was to investigate the transmission and genetic identity of Streptococcus mutans strains in mother-child pairs from Cordoba, Argentina in order to establish whether the mother was the main source of infection of the child.

Methods: Seventeen mother-child pairs were analyzed, with samples taken of whole nonstimulated saliva and dental plaque when each child was 18 months old. The mothers gave their written, informed consent to participate in the study.

Evaluation of clinical dental variables to build classifiers to predict celiac disease.

Objective: The aim of this study was to evaluate the use of salivary variables to build statistical models for predicting celiac disease in symptomatic children.

Materials And Methods: The study group consisted of 52 children with celiac disease diagnosed by bowel biopsy, grade III or IV (4 to 12 years old, both sexes) and 23 healthy children as a control group. A logistic regression model was applied to evaluate an individual's belonging to one group or another.

[Salivary factors associated to the prevalence and increase of dental caries in rural schoolchildren].

Objective: To evaluate the association between saliva and prevalence of dental caries.

Methods: Two-year longitudinal study in rural schoolchildren at Cruz del Eje, Argentina between 2000 and 2002. The study population comprised all schoolchildren (N=196) aged 5 to 14 years of both sexes attending eight rural schools.

Early acquisition of Streptococcus mutans for children.

Existing evidence reveals that in Early Oral Infection the main route of transmission of Streptococcus mutans is mother-child saliva contacts and that initial acquisition takes place during a specific period of time denominated "Window of Infectivity" that lapses between 6 and 30 months of the child's life, with a higher risk between 18 and 30 months of age. The aim of the present study was to analyze Early Oral Infection. The levels of Streptococcus mutans in saliva and bacterial plaque in the binomial mother-child 6 to 18 months after childbirth were evaluated.

[Assessment of health and record of disease in the promotion of health oral].

Background: At present, epidemiologic dentistry has numerous indexes to measure illness such as DMFT, dmft and S-OHI which are broadly used for illness diagnosis in different population groups. On the other hand, the index INSAO proposed differs from the approach focused on the disease itself. INSAO offers a parameter to measure the degree of health of teeth and gums and thus provides the patient with the information about their health.

Oral health and salivary factors in rural schoolchildren.

The aim of the present study was to assess the association between some salivary factors and the oral health status of rural schoolchildren of Córdoba (Argentina). The study involved 19 students (aged 5-14 years) who attended 8 rural schools of the region. We determined indices (r)dmf-t, (r)DMF-T and S-OHI.

Effect of Chitosan and Sodium Alginate on the adherence of autochthonous C. Albicans to oral epithelial cells (in vitro).

The aim of the present study was to evaluate the effect of Heavy Molecular Weight Chitosan (HMWCh) and Sodium Alginate (NaAl) on fungal adherence. C albicans was identified and isolated from non-stimulated saliva extracted from male and female healthy adults. The minimum inhibitory concentration (MIC) was determined for each of the biopolymers.
