Evaluation of acceptance and preference of topical lidocaine application versus articaine injection anesthesia after nonsurgical periodontal treatment: A randomized clinical trial.

Background: To compare acceptance and preference of topical lidocaine gel anesthesia with articaine injection anesthesia in patients with moderate periodontitis undergoing scaling and root debridement.

Methods: Ninety-one patients completed this randomized multicenter split-mouth controlled study and underwent two separate periodontal treatment sessions on different days, one with a topical intrapocket lidocaine gel application and the other with an articaine injection anesthesia in a different order depending on randomization. Parameters measured were the patients' preference for topical lidocaine gel anesthesia or injection anesthesia with articaine (primary efficacy criterion), their maximum and average pain, and their intensity of numbness as well as experience of side effects; the probing depth; and the dentists' preference and their evaluations of handling/application, onset and duration of anesthetic effect, and patient compliance.

[Pyostomatitis vegetans. Numerous pale yellow dots on inflammatory red ground - A case report.].

Pyostomatitis vegetans is a disease of the gingiva and the oral mucosa with noticeable, uncommon morphology. Clinical characteristics of this rare disease and considerations regarding differential diagnosis are described. Pyostomatitis vegetans is frequently associated with chronic inflammatory bowel diseases and can, thus, give a diagnostic hint at an existing ulcerative colitis or Crohn’s disease.

Periodontal disease in patients with ankylosing spondylitis.

Objective: Ankylosing spondylitis (AS) and periodontal disease (PD) are characterised by dysregulation of the host inflammatory response, resulting in soft and hard connective tissue destruction. AS has been related to other inflammatory diseases, however, there is a paucity of data on whether AS is associated with inflammatory PD.

Methods: The association between AS and PD was examined in 48 patients with AS and 48 healthy controls, matched for age and gender.

Effects of Porphyromonas gingivalis on cell cycle progression and apoptosis of primary human chondrocytes.

Background: It has been suggested that bacterial infections have a role in the pathogenesis of rheumatoid arthritis (RA). P gingivalis, a Gram-negative, anaerobic rod, is one of the major pathogens associated with periodontal disease.

Objective: To examine P gingivalis infection and its effects on cell cycle progression and apoptosis of human articular chondrocytes.
