Clinical evaluation of the periodontal health condition and oral health awareness in Parkinson's disease patients.

OBJECTIVE AND BACKGROUND: The objectives were to compare periodontal status between subjects with and without Parkinson's disease (PKD) to determine the influence of PKD on periodontal disease. This study was conducted to evaluate the relationship of periodontal status with severity of PKD. MATERIALS AND METHODS: This study was conducted on 45 subjects with PKD (subjects with PKD were divided into 5 groups from group 2 to group 6 according to Hoehn and Yahr stages) and 46 control subjects (group 1). Probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI) and percentage of bleeding sites (%BoP) were evaluated. All subjects were interviewed regarding their practice of oral hygiene and access to professional dental care. RESULTS: There were statistically significant differences in PD, CAL, GI, PI and %BoP in subjects with PKD and controls (p < 0.001). All the evaluated periodontal clinical parameters and indices deteriorate with increase in severity of PKD. The mean PD value increased from 2.75 mm for group 1 to 6.17 mm for group 6, and mean CAL value increased from 3.14 mm for group 1 to 6.74 mm for group 6. The mean GI, PI and %BoP values increased from 0.55, 1.35 and 20.37 to 2.66, 3.80 and 70.86, respectively with increasing severity of PKD. CONCLUSION: There is a need for dental care and encouragement to use plaque control methods for subjects with PKD as periodontal pathology presented a high prevalence even in the early stages of PKD.

Clinical and microbiological effects of levofloxacin in the treatment of chronic periodontitis: a randomized, placebo-controlled clinical trial.

AIM: The aim of the present study was to evaluate the clinical and microbiological effect of systemic levofloxacin (LFX) as an adjunct to scaling and root planing (SRP) in patients with chronic periodontitis (CP). METHODS: Sixty-five patients with CP were randomly divided into a test (n = 33, SRP and LFX 500 mg, once daily [o.d.]) and a control group (n = 32, SRP and placebo, o.d.). Plaque index (PI), gingival index (GI), percentage of sites with bleeding on probing (%BoP), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, 10 days, and 1-, 3-, and 6-month intervals. The percentage of sites positive for Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), Porphyromonas gingivalis, and Tannerella forsythia were recorded at baseline and at 3 and 6 months. RESULTS: Patients receiving LFX showed statistically-significant improvements in mean PD and CAL. The intergroup difference in PI, GI, and%BoP was not significant at any interval. There was a reduction in the percentage of sites positive for periodontopathic bacteria over the duration of the study in both groups, and a statistically-significant reduction in the number of sites positive for A. actinomycetemcomitans in the LFX group (P < 0.001). CONCLUSION: Levofloxacin was found to significantly improve the clinical and microbiological parameters in CP individuals.
