Recent studies report that individuals with polymorphisms in the genes that encode for interleukin (IL)-1α and IL-1β (IL-1A and IL1B, respectively) and for IL-1 receptor antagonist (IL-1RN) may be more susceptible in developing peri-implantitis. Therefore, the current systematic review evaluates what is reported about the role of genetics, more specifically of single nucleotide polymorphisms (SNP) on IL-1 and v...

Most cases of halitosis are due to inadequate oral hygiene, periodontit...

Lobato, Joana Cristina Rico Farto; Vilhena, Mafalda Alexandra dos Santos; Izidoro, Catarina; Alves, Ricardo Castro; Proença, Luís

Background: Topical coadjuvants might be indicated to increase the results of nonsurgical periodontal treatment and overcome some of its limitations. The aim of this study was to evaluate the clinical benefits of a single topical application of 0.8% hyaluronic acid (HA) as a coadjuvant to scaling and root planing (SRP) in periodontal patients. Materials and Methods: Sixteen patients diagnosed with periodontitis...
