Abstract
The aim of this study was to investigate whether there is an association between inducible in single nucleotide polymorphisms in nitric oxide synthase (rs2297518 and rs2779249) and persistent apical periodontitis. A total of 291 Brazilian subjects were included: 125 with signs/symptoms of persistent apical periodontitis and 166 with root canal-treated teeth exhibiting healthy perirradicular tissues. Endodontically treated patients were followed up after 1 year. The two single nucleotide polymorphisms in nitric oxide synthase were analysed using real-time polymerase chain reaction. Chi-square test and odds ratio with 95% confidence intervals were performed to compare genotype distributions between ‘healed’ and ‘persistent apical periodontitis’ groups (p < 0.05). Logistic regression analysis was used to evaluate SNP–SNP interactions. The allele and genotype distributions for the polymorphisms between the persistent apical periodontitis and healed groups were not statistically significant (p > 0.05). In the logistic regression analysis, the polymorphisms were not associated with persistent apical periodontitis and SNP–SNP interactions.
期刊介绍:
The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues.
The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses.
The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
