Effect of Orthodontic Banding on Localized Oral Lactobacilli

Candida albicans in the Oral Cavities of Diabetics

SYNOPSIS IN INTERLINGUA CANDIDA ALBICANS IN LE CAVITATE ORAL DE DIABETICOS.—Le relation del saccharomycete Candida albicans con diabete e con morbo periodontal esseva studiate in 200 diabeticos a morbo regulate, 200 diabeticos a morbo non regulate, e 200 nondiabeticos. Le gruppos esseva subdividite additionalmente in categorias a subjectos edentule e dentule. Le saccharomycete esseva isolate non minus frequemente ab le cavitate oral del diabeticos que ab le cavitate oral de nondiabeticos. Lesiones periodontal esseva observate non minus frequemente in le nondiabeticos que in le diabeticos. Solmente le diabeticos a morbo non regulate exhibiva un levemente plus alte incidentia de certes del symptomas de morbo periodontal. In le patientes edentule le condition diabetic non pareva favorar le disveloppamento de inflammation del mucosa alveolar.

Penicillin-Resistant Streptococci from the Saliva

SYNOPSIS IN INTERLINGUA STREPTOCOCCOS PENICILLINO-RESISTENTE ISOLATE AB LE SALIVA DE PATIENTES CON FEBRE RHEUMATIC.— Le presentia de streptococcos penicillino-resistente in le cavitate oral representa un periculo potential pro le salute general de patientes con febre rheumatic e congenite morbo cardiac quando illes se subjice a un tractamento dental. Esseva studiate le saliva de patientes con febre rheumatic sub tractamento penicillinic a diurne dosage oral. Le streptococcos hemolytic alpha e nonhemolytic esseva identificate per le tests morphologic e biochimic de uso in le microbiologia diagnostic. Le resultatos del studio monstra que 45 ex 58 patientes rheumatic (77,5 pro cento) habeva disveloppate lineas penicillino-resistente de streptococcos, in comparation con solmente 7 del 58 patientes de controlo (12 pro cento).
