Previous issue date: 2011-01-25 / Based on the premisse that the oral trauma might cause the introduction of bacteria in the
bloodstream, this study was developed aiming at investigating the frequency of transitory
bacteremia in different dental procedures and the usual in dogs and the risk of infectious
endocarditis in these animals. 36 dogs were were evaluated and classified as to the degree of
the periodontal disease in six treatments: T1 (n=5) healthy gum/ negative control;T2(n=6)
mild gingivitis; T3 (n=6) moderate or severe gingivitis/feeding;T4(n=6)moderate or severe
gingivitis / toothbrushing t5(n=6)moerate or severe periodontitis/ removal of subgum plaque
;T5(n=7) severe periodonctis / exodontia. Blood samples for hemogram and hemoculture
were obtained before the procedures, and two for hemoculture with thirty-minute breaks after
the procedures. The hemoculture was performed in triphasic hemobac and the hemograms in
electronic counter. After that, the animals were sumitted to cardiac assessment by ultrasound
tests. A great accumulation of plaque was observed in animals of different ages especially in
the upper molar and premolar teeth. The hemogram revealed values indicative of ANN,
normal leucometria and trombocitopenia in all groups. There were 22 % of positive
hemocultures beforem, 32,2% immediately after and 30 minutes after the procedures with
mostly Staphylococcus sp and Streptococcus sp .In the ultrasound tests there were no
alterations indicative of proliferative vegetative lesions. The diameters of the atria and
ventricles were smaller in the animals with periodontitis. The cardiac debt was also smaller in
these animals. The thickness of the walls of the ventricles were smaller in the healthy animals.
The average mitral thickness did not significantly vary in the healthy animals and the ones
with PD. The average values were compatible with endocardiosis (3,39 +_ 0,71) in 31
animals. The two represent the measurement of the diameter of the root of the Aorta out of the
limits and the relation LV/AO made cardiopathy evident in at least 15 animals. The cardiac
debt was smaller in the animals with PD within the group of weight associated with other
parameters of the ventricular function suggest a PD effect on the cardiocirculatory activity. / Com base na premissa de que o trauma oral pode provocar a introdu??o de bact?rias na
corrente sangu?nea, este estudo foi desenvolvido com a finalidade de investigar a freq??ncia
de bacteremia transit?ria em diferentes procedimentos odontol?gicos e usuais em c?es e o
risco de endocardite infecciosa nesses animais. Foram avaliados 36 c?es classificados quanto
ao grau da doen?a periodontal em seis tratamentos: T1 (n=5) gengivas saud?veis / Controle
negativo; T2 (n=6) - gengivite leve; T 3 (n= 6) gengivite moderada ou grave / alimenta??o;
T 4 (n= 6) gengivite moderada ou grave / escova??o; T 5 (n=6) - periodontite moderada ou
grave / remo??o da placa subgengival; T6 (n=7) periodontite grave / exodontia. Amostras de
sangue para hemograma e hemocultura foram obtidas antes dos procedimentos, e duas para
hemocultura com intervalos de 30 minutos ap?s os procedimentos. A hemocultura foi
realizada em Hemobac trif?sico e os hemogramas em contador eletr?nico. Ap?s, os animais
foram submetidos ? avalia??o card?aca pela ecocardiografia. Em animais de diferentes idades
foi observado grande ac?mulo de placa, sobretudo nos pr?-molares e molares superiores. O
hemograma revelou valores indicativos de ANN, leucometria normal e trombocitopenia em
todos os grupos. Obteve-se 22% de hemoculturas positivas antes, 32,2% imediatamente e 30
minutos ap?s os procedimentos com predom?nio de Staphylococcus sp e Streptococos sp. Na
avalia??o ultrassonogr?fica n?o foram evidenciadas altera??es indicativas de les?es
proliferativas vegetativas. Os di?metros dos ?trios e ventr?culos foram menores nos animais
com periodontite. Tamb?m o d?bito card?aco foi menor nesses animais. A espessura da parede
do ventr?culo foi menor nos animais sadios. A espessura m?dia da mitral n?o variou
significativamente entre animais sadios e com DP. Os valores m?dios foram compat?veis com
endocardiose (3,39 ? 0,71) em 31 animais. Dois apresentaram a mensura??o do di?metro da
raiz da aorta fora dos limites e a rela??o VE/AO evidenciou cardiopatia em pelo menos 15
animais. O d?bito card?aco menor em animais com DP na mesma faixa de peso em associa??o
com outros par?metros da fun??o ventricular sugere um efeito da DP sobre a atividade
cardiocirculat?ria.
