ABSTRACT
The purpose of this study is to identify the presence of Campylobacter species (C. rectus, C. concisus, C. gracilis and C. ureolyticus) in Chilean patients with chronic periodontitis, and to establish the relationship of these microorganisms with the periodontal conditions of smoker and non-smoker patients. Subgingival plaque samples were collected from four periodontal-affected tissue sites of 15 smoker and 15 non-moker patients with chronic periodontitis. A sample per quadrant was obtained, with a probing depth of 6 mm and an insertion loss of >3 mm in each patient. Polymerase chain reaction (PCR) was performed with the specific 16S rDNA primers for the molecular detection of C. rectus and C. gracilis, specific cpn60 primers for C. concisus and hsp60 primers gene for C. ureolyticus. Campylobacter species showed an overall prevalence of 93.3% in periodontal patients, while C. rectus was the most frequent one (80%), followed by C. concisus (66.7%), C. gracilis (33.3%), and C. ureolyticus (10%). Only C. gracilis showed a statistically significant (p = 0.002) association with chronic periodontitis among samples from smoker and nonsmoker patients. A high prevalence of the Campylobacter genus in the analyzed populations (93.3%) was found, being C. rectus the most frequent (80%) species. Besides, C. gracilis showed a statistically significant association between smoker state and chronic periodontitis.
RESUMO
O objetivo deste estudo é identificar a presença de espécies de Campylobacter (C. rectus, C. concisus, C. gracilis e C. ureolyticus) em pacientes chilenos com periodontite crônica, e estabelecer a relação desses microrganismos com as condições periodontais de pacientes fumantes e não fumantes. Amostras de placa subgengival foram coletadas de quatro locais de tecido periodontal afetado de 15 pacientes fumantes e 15 não fumantes com periodontite crônica. Obteve-se uma amostra por quadrante, com profundidade de sondagem 6 mm e perda de inserção > 3 mm em cada paciente. A reação em cadeia da polimerase (PCR) foi realizada com os primers específicos 16S rDNA para a detecção molecular de C. rectus e C. gracilis, primers específicos de cpn60 para C. concisus e gene primers de hsp60 para C. ureolyticus. As espécies de Campylobacter apresentaram uma prevalência geral de 93,3% nos pacientes periodontais, enquanto C. rectus foi o mais frequente (80%), seguido por C. concisus (66,7%), C. gracilis (33,3%) e C. ureolyticus (10%). Apenas C. gracilis apresentou associação estatisticamente significante (p = 0,002) com a periodontite crônica entre as amostras de pacientes fumantes e não fumantes. Observou-se alta prevalência do gênero Campylobacter nas populações analisadas (93,3%), sendo C. reto as espécies mais frequentes (80%). Além disso, C. gracilis mostrou associação estatisticamente significante entre estado de fumante e periodontite crônica.
