Implant position for supporting maxillary over-denture: a clinical study.

Area of Science:

• Periodontology
• Microbiology
• Biomaterials Science

Background:

• Chronic periodontitis affects a significant portion of the adult population.
• Supportive periodontal therapy (SPT), including scaling and root planing (SRP), is the standard of care.
• Novel therapeutic adjuncts are needed to improve treatment outcomes.

Purpose of the Study:

• To compare the efficacy of SRP alone versus SRP combined with silica dioxide colloidal solutions (SDCS) in treating chronic periodontitis.
• To evaluate the impact of SDCS on microbial load and clinical parameters.

Main Methods:

• A split-mouth design study involving 20 adult patients (35-55 years) with chronic periodontitis.
• Two non-adjacent sites per patient were treated with either SRP alone or SRP with SDCS.
• Clinical pocket depth (PD) and microbial analysis (MA) were assessed at baseline and day 15.

Main Results:

• Local delivery of SiO2 via SDCS gel resulted in a statistically significant reduction in total bacteria, Tannerella forsythia, and Treponema denticola.
• The combination therapy demonstrated enhanced microbial reduction compared to SRP alone.

Conclusions:

• Silica dioxide colloidal solutions (SDCS) act as an effective adjuvant therapy when used with scaling and root planing (SRP).
• SDCS gel is recommended for the management of moderate to severe chronic periodontitis to improve microbial control.
