Omega-3 fatty acids as an adjunct to non-surgical periodontal therapy

shutterstock_57647551

This review assessing the adjunctive effect of omega-3 (ω-3) fatty acids and non-surgical periodontal therapy (SRP)on probing pocket depth (PPD) and the clinical attachment level (CAL) included 10 RCTs. The findings suggest that adjunctive ω-3 fatty acids provides a 0.39 mm improvement in PPD and 0.41 mm of CAL gain.

This review comparing of air polishing devices with conventional periodontal therapy (hand instrumentation and/or ultrasonic debridement), in patients undergoing periodontal maintenance therapy included 14 RCTs. The findings suggest that they have comparable clinical efficay although the evidence is of low certainty.

This Cochrane review update comparing full-mouth scaling/disinfection (FMS/D) to conventional quadrant scaling for periodontitis for the treatment of periodontitis included 20 RCTs. However there is still no clear evidence that FMS/D approaches provide additional clinical benefit compared to conventional treatment.

Dietary omega-3 fatty acids as an adjunct to non-surgical periodontal treatment

Fatty acid supplementation may have involved omega - 3 or -6 oils or both.

This review assessing the impact of dietary omega-3 fatty acids as an adjunct to non-surgical periodontal treatment when compared with periodontal treatment alone included 10 trials ivolving a total of 467 patients. The studies found statistically significant improvements in clinical attachment level (CAL) and periodontal probing depth (PPD) but the studies are generally small and short-term.

This review of the accuracy of clinical and radiographic measurements of infrabony periodontal defects inclded 10 studies reporting on 17 comparisons. the findings suggest that clinical and radiographic measurements of the bone level underestimate the true bone loss by an average of 1mm but the evidence is only of low to moderate certainty.

This review of the clinical efficacy of tricalcium phosphates (-containing) biomaterials in the treatment of periodontal infra-bony defects includes 16 RCTs. While the findings suggest improvements in pocket depth and clinical attachment level only 6 of the studies contributed to the meta-analyses and the number of events and studies are small so the findings should be viewed cautiously.
