RESUMO
Background: High fluorine concentrations in drinking water are associated with a decrease in the amount of salivary S mutants. Taking into account that clinical dental fluorosis can appear with 1.5 ppm of fluorine in the drinking water, fluorine concentration in Mami-a is 2.4 ppm. Aim: To quantify salivary S mutans in school age children from Mami-a, a zone with a high fluorine content in the drinking water, during one year. Material and methods: During 1997 and 1998, dental health was assessed and salivary samples were obtained from 51 children (27 male) aged 10 ñ 2 years to quantify S mutans. Results: Most children studied had more than 105 salivary S mutans colony forming units. No changes in the rates of infection or dental health characteristics were observed during the observation year. Conclusions: High fluorine content in the drinking water did not have an effect on salivary S mutans infection in this population

Background: Salivary Streptococci mutans contamination is considered the main microbiological risk factor for the initiation of caries. Aim: To assess the oral health of pregnant women, counting Salivary Streptococci mutants. Patients and methods: One hundred seventy four pregnant women, in the first, second and third trimester of pregnancy, aged 27 ñ 5 years old, consulting at a public primary health center, were studied. Puerperal women that had their delivery two months before, were studied as a control group. Salivary samples were obtained and Streptococci mutans colonies were counted using quantitative and semiquantitative methods. Results: There was a good concordance between both counting methods. No differences in Streptococci mutans counts were observed among the three groups of pregnant women, but the latter as a group had higher counts than puerperal women. Women with more than 5 caries had also higher counts. Conclusions: Semiquantitative Streptococci mutans counts are easy, rapid and non invasive and have a good concordance with quantitative counts in saliva

El presente trabajo muestra la correlación entre las actividades enziniticas en el fluido crevicular y la enfermedad periodontal. Las mediciones de las actividades de la Glutámico-oxaloacético transaminasa (GOT) y Láctico deshidrogenasa (LDH) en pacientes con enfermedad periodontal avanzada del adulto y sujetos clinicamente sanos se estableció adaptando un micrométodo espectrofotométrico. Cuando se compararon las actividades enzimáticas del grupo experimental con el grupo control, se observó una diferencia estadisticamente significativa en la actividad de ambas enzimas (p<0,005 para GOT y p<0,0001 para LDH). Las mediciones de volúmenes de fluido crevicular tambien resultaron estadisticamente significativas al Comparar los pacientes del grupo experimental con los del grupo control p<0,0001)

La bioquímica clínica en relacíon con la enfermedad periodontal puede proporcionarmos una valiosa información acerca de los episódios de actividad que presenta esta enfermedad. Los autores han centrado esta revisón em la actividad enzimática presente en el fluido gingival, como resultado de la destrucción tisular. La aplicación de métodos, ampliamente utilizados en Medicina tienen gran importancia en el diagnóstico y tratamiento de los pacientes con alto riesgo de padecer enfermedad periodontal
