The role and impact of viruses on cancer development.

This review focuses on three major aspects of oncoviruses' role in cancer development. To begin, we discuss their geographic distribution, revealing that seven oncoviruses cause 20% of all human cancers worldwide. Second, we investigate the primary carcinogenic mechanisms, looking at how these oncogenic viruses can induce cellular transformation, angiogenesis, and local and systemic inflammation.

Association of Down syndrome with periodontal diseases: Systematic review and meta-analysis.

Background: Down syndrome (DS) is distinguished by cognitive disability, a concave profile, and systemic complications. Oral diseases have been reported to be common in DS patients.

Objective: To investigate the association between DS and periodontal diseases.

Occlusal trauma is associated with periodontitis: A retrospective case-control study.

Background: Excessive occlusal forces and occlusal trauma have been implicated as co-destructive factors for periodontitis in animal models. The objective of this study was to assess the association between occlusal trauma and periodontitis.

Methods: A total of 167 cases and 205 controls were included for analysis.

Association between human cytomegalovirus and periodontitis: A systematic review and meta-analysis.

Background And Objective: Human cytomegalovirus (HCMV) has been associated with periodontitis and apical periodontitis. The objective of this systematic review was to evaluate the association between HCMV and periodontitis, and apical periodontitis of endodontic origin.

Material And Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines and registered in the International prospective register of systematic reviews (PROSPERO).

Association between traumatic occlusal forces and periodontitis: A systematic review.

Objective: Occlusal adjustment is commonly recommended for patients with periodontitis and traumatic occlusion. The objective of this systematic review was to analyze available evidence for the association between traumatic occlusal forces and periodontitis.

Methods: Two focused questions were proposed: What is the effect of traumatic occlusal forces on periodontal parameters in patients with and without periodontitis? And what is the effect of occlusal interventions on periodontal parameters in patients with periodontitis? A systematic review of clinical and observational studies was performed and presented in narrative form.

Weak Evidence Hinders the Understanding of the Benefits of Periodontal Therapy on Glycemic Control in Patients With Diabetes and Periodontitis.
