PURPOSE To evaluate the efficacy of a novel multi-directional power toothbrush in reducing plaque and gingivitis relative to a standard manual toothbrush control. METHODS This 4-week, randomized and controlled, single-center, parallel group, examiner-blinded clinical study enrolled adults with mild-to-moderate gingivitis. At baseline, pre-treatment gingivitis and plaque levels were assessed v...

BACKGROUND Atherosclerotic plaques indicate the occurrence of ischemia events and it is a difficult task for clinical physicians. Grape seed proanthocyanidin extract (GSPE) has been reported to exert an antiatherogenic effect by inducing regression of atherosclerotic plaques in animal experimental studies. In this study, the antiatherogenic effect of GSPE has been investigated in clinical use. ...

Background: T cell activation is discussed as an important factor in the pathogenesis of psoriasis. Recently, a lot of attention has been paid to the role of superantigens in T cell activation in the pathogenesis of psoriasis. In this study, the role of staphylococcal superantigens in the pathogenesis of psoriasis with identification of staphylococcal toxin levels in the skin lesions of p...

In this paper we study the problem of Grid access control in environments with high confidentiality requirements and a large number of users. We propose a novel access control mechanism, Sygn, that implements decentralized permission storage and management. All permissions in Sygn are encoded in certificates, which are stored by their owners and used when required. Sygn allows for decentralized...

An ion-sensitive field-effect transistor was used to monitor changes in pH following exposure of plaque samples to sucrose. A total of 9O plaque samples were removed from sound enamel, incipient white spot lesions, or cavities of 84 children and placed in a microholder. Sucrose(5% solution) was placed onto the plaque sample and the pH followed for 30 rain by inserting the microelectrode into th...

AIM To compare the efficacy of turmeric mouthwash and chlorhexidine gluconate mouthwash in prevention of gingivitis and plaque formation. MATERIALS AND METHODS A total of 100 randomly selected subjects visiting the Department of Periodontology at Bharati Vidyapeeth Deemed University, Dental College and Hospital, were considered for the study. The gingival index (GI) by Loe and Silness was rec...

statement of problem: dental caries is one of the most common chronic diseases in children. the balance between demineralization and remineralization of the decayed teeth depends on the calcium and phosphate content of the tooth surface. therefore, if a product such as casein phospho peptides - amorphous calcium phosphate (cpp- acp) which can significantly increase the availability of calcium a...

The aim of this study was to investigate the purported link between oral hygiene and preterm birth by using image analysis tools to quantify dental plaque biofilm. Volunteers (n = 91) attending an antenatal clinic were identified as those considered to be "at high risk" of preterm delivery (i.e., a previous history of idiopathic preterm delivery, case group) or those who were not considered to ...
