Clinical and biochemical effects of dark chocolate in moderate chronic periodontitis
Authors
Abstract:
Introduction: Antioxidant agents such as cocoa could have some benefits in treatment of inflammation including periodontitis. The aim of this study was to investigate the effects of cocoa consumption on moderate chronic periodontitis. Materials &Methods: This single-blind randomized clinical trial study was performed on 40 subjects who were randomly divided into two groups. Treatment group received 30 gr dark chocolate (78% cocoa) and control group received 22.5 gr white chocolate three times a day for 4 weeks. Saliva samples were collected from patients at baseline and t wenty-eight days after eating chocolate. Probing pocket depth (PPD), Gingival index (GI, Silness and Loe), Modified papillary bleeding index (MPBI, Barnett), Clinical attachment loss (CAL) were recorded at baseline and 2nd, 4th, 6th, 8th weeks later in ramfjord teeth. Total antioxidant capacity (TAC) and lipid peroxidation of saliva were estimated by Ferric reducing antioxidant power (FRAP) and Tiuborbituric acid reactive substances ( TBARS ) methods. Data of clinical parameters were analyzed using t-test and repeated measures test. Biochemical parameters were analyzed using t-test. Results: Intra-group comparison of clinical parameters demonstrated significant decrease in both groups (p<0.0001) and inter-group comparison showed significant decrease of MPBI in treatment group, (p<0.03). MPBI and GI were significantly decreased in treatment group compared to the control in the weeks of 4th, 6th and 8th, according t-test ( GI4, P=0.008-GI6, P=0.008-GI8, P=0.009), (MPBI4, MPBI6, MPBI8, P<0.0001). Treatment group showed the increase in FRAP, (p<0.00001 ) and decrease in TBARS, ( P<0.015) which were statically significant in compare with control group. Conclusion: Consuming dark chocolate could increase TAC and decrease lipid peroxidation, gingival bleeding and inflammation.

Clinical benefit and preservation of flavonols in dark chocolate manufacturing.
The consumption of high-cacao-content chocolate has been associated with positive health benefits ascribed to flavanol [corrected] antioxidants derived from the ground, fermented cocoa seeds of Theobroma cacao. However, flavanols [corrected] impart a bitter, astringent flavor to foodstuffs, frequently masked in chocolates and confections by aggressive processing and adulteration with other flav...

Background: Consumption of dark chocolate has been often hypothesized to have a role in the prevention of chronic diseases. The objective of this study was to investigate the effects of consumption of dark chocolate (DC) on serum oxidative stress and blood pressure (BP) in patients with metabolic syndrome (MetS). Methods: An 8-week parallel randomized clinical trial involving 114 patients with ...

When we first entered this scientific area about 10 years ago, we did not fully appreciate the emotional content of discussions involving chocolate. Contacts between medical scientists and the lay press tend to be sporadic. When chocolate is the issue, however, the lay press interest becomes intense and widespread. We have participated in many dozens, probably hundreds, of interviews about our ...

Background and purpose: Ascorbic acid is an important antioxidant and its depletion is a risk factor for periodontal diseases. This study aimed to evaluate the effect of 2% atorvastatin dentifrice and ascorbic acid on improving clinical periodontal parameters in patients with chronic periodontitis. Materials and methods: This clinical trial included 72 patients with moderate and severe chronic...

A total of 171 taxa was represented among 1,900 bacterial isolates from 60 samples of sites affected with moderate periodontitis in 22 mature adult humans. The composition of the subgingival sulcus flora was statistically significantly different from that of the adjacent supragingival flora and the subgingival flora of 14 people with healthy gingiva, but was not significantly different from tha...
