ABSTRACT

OBJECTIVES: Virgin coconut oil (VCO) pulling has antimicrobial activity and has been promoted as beneficial to oral health; however, limited information exists on its clinical effectiveness. This study aimed to compare the microbiological effects of VCO with palm oil (PO) pulling when used as an adjunctive oral hygiene care. MATERIALS AND METHODS: Thirty-six volunteers with gingival inflammation were randomly assigned to start with (1) VCO (test) and (2) PO (control) interventions in a crossover design. Oil pulling was performed for 28 days adjunctively to oral hygiene routine. After a 21-day wash-out period, the participants switched the oil type and restarted the protocol. Plaque samples were collected for microbial culture at baseline, after the first oil pulling period, after washout, and after the second oil pulling period. The total, aerobic, and anaerobic bacteria and Mutans streptococci (MS) counts were recorded. The mean differences between VCO and PO were compared by paired t-test. RESULTS: The number of total, aerobic, or anaerobic bacteria after 28 days of oil pulling was not significantly different from baseline in both PO and VCO groups. However, PO pulling demonstrated a significant reduction from baseline of MS count (P = 0.010), while VCO pulling showed no significant reduction. There was no statistically significant difference in the mean changes of any microbiological parameters between the two treatments. CONCLUSIONS: VCO pulling did not show statistically significant superior benefit against plaque bacteria over PO pulling. Using PO pulling as an adjunctive oral hygiene care may reduce the number of MS, but this requires further investigations.

ABSTRACT

OBJECTIVES: To evaluate the association between the severity and extent of periodontitis and arterial stiffness using the cardio-ankle vascular index (CAVI). MATERIALS AND METHODS: A cross-sectional study of 2888 Electricity Generation Authority of Thailand (EGAT) employees aged 44-78 years was conducted. The severity of periodontitis was evaluated based on mean clinical attachment level (CAL). The percentage of sites with CAL ≥ 5 mm was used to divide the extent of periodontitis into healthy (0%), localized (> 0-< 30%), and generalized (≥ 30%). The CAVI value, a novel blood pressure-independent arterial stiffness parameter, was analyzed as both continuous and categorical data (low: < 9 or high: ≥ 9). Regression analysis was used to estimate the level of association. RESULTS: The participants demonstrated a mean CAL, % sites with CAL ≥ 5 mm, and a CAVI value of 3.2 ± 1.2 mm, 16.0 ± 20.8%, and 8.24 ± 1.12, respectively. Higher mean CAVI was observed with greater mean CAL and % sites with CAL ≥ 5 mm. The mean CAVI of the healthy, localized, and generalized periodontitis groups were 8.01 ± 1.11, 8.22 ± 1.12, and 8.51 ± 1.04, respectively (p < 0.01). Linear and logistic regression analysis demonstrated a significant relationship between CAVI and all periodontal variables with ß = 0.004-0.17 and OR = 1.01-1.58, respectively. CONCLUSIONS: There is a significant dose-dependent association between the severity and extent of periodontitis and arterial stiffness measured by CAVI in Thai adults. CLINICAL RELEVANCE: Preventing arterial stiffness, an early sign of cardiovascular events, by controlling the emerging risk factors, such as periodontitis, might have a high impact on health promotion.
