Title: Periodontal Health and Relative Quantity of Porphyromonas gingivalis among Fixed Orthodontic Wearers
Author: Ibrahim, Mahdia Fathi Mohamed Salih
Abstract: Background: Fixed orthodontic appliances blamed to increase the amount of plaque around the teeth, and increase the counts of periodontopathic bacteria mainly, the gram-negative obligate anaerobe Porphyromonas gingivalis which cause gingival inflammation and periodontal destruction. The objectives of the study was to measure changes in periodontal health parameters and to assess the variation, in the counts of subgingival P. gingivalis before orthodontic appliances were fixed and then one month and three months after treatment and to correlate between the clinical parameters and quantification of P. gingivalis at three different times. Methods: Forty three malocclusion patients were selected, all were seeking orthodontic treatment (14 male and 29 female). Plaque index (PI), gingival index (GI), probing pocket depth (PPD) and clinical attachment level (CAL) were measured before orthodontic appliances were fixed and then one month and three months after appliances. Periodontal measurements were performed using periodontal probe. Plaque index (PI) as well as gingival index (GI) was recorded by using (Silness and Löe index 1964), (Löe and Silness index 1963) respectively. Paper points were used to collect subgingval plaque. Real-time quantitative polymerase chain reaction was used to quantify P. gingivalis in subgingival plaque before orthodontic appliances were fixed and then one month, and three months after treatment started . Results: Plaque index, gingival index and quantity of P. gingivalis were significantly inceased after one month and three months. The mean of PI ±SD at base line (1.06± .14), after 1month (1.43 ±0.45) and after three months (1.60 ±0.61) (P= 0.001) The mean ± SD of GI at base line (1.09 ± 0.17), after 1month (1.72 ±0.53) and after three months (1.84 ±0.73) (P= 0.0001) The mean ± SD of quantity of P. gingivalis at base line was) 0.028 ±0.0 86( after one month )4.618 ±15.96( and after three months )9.706 ± 32.303( (P=0.001) . PI and GI were significantly correlated with each other but there was in significant correlation between them and the quantity of Porphyromonas gingivalis . Conclusions: The placement of fixed orthodontic appliance affects the accumulation and composition of the sub gingival dental plaque resulting in more gingival inflammation. The carriage and the amount of P. gingivalis in subgingival plaque were high after one and three months of the beginning of orthodontic treatment.
