Seventy volunteers were randomly allocated to Group A (tapered-tip toothbrush) or Group B (end-rounded toothbrush). At baseline appointment (Day 0), volunteers underwent plaque examination using the Improved Plaque Identification Index. Under supervision, they brushed their teeth for 1 minute with their assigned toothbrushes and the plaque examination was repeated. Volunteers continued the oral hygiene regimen (assigned toothbrush and a regular dentifrice provided by the researchers) for 7 days. The experimental procedures of Day 0 were then repeated. Separate statistical analyses were performed for mean percent reduction of plaque in the whole-mouth, interproximal and gumline scores at both times, using Mann-Whitney test, p<0.05. After a single toothbrushing, on Day 0, mean percent plaque was significantly reduced in both groups (p<0.05), with statistically greater reductions of whole-mouth (21.39±12.44 vs. 11.40±11.17), gumline (6.32±7.37 vs. 2.89±4.57) and interproximal (10.82±10.49 vs. 5.21±7.68) for Group A as compared to Group B. However, on day 7, no significant difference was observed between groups for whole-mouth (29.94±20.91 vs. 26.58±18.64), gumline (14.04±18.82 vs. 13.78±17.63) and interproximal surfaces (26.41±22.77 vs. 23.12±20.98) (p>0.05). In conclusion, on Day 0, Group A presented higher efficacy in supragingival plaque removal than Group B, as reflected by whole-mouth, gumline and interproximal plaque scores.","PeriodicalId":7033,"journal":{"name":"Acta odontologica latinoamericana : AOL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76773064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate whether CI and arterial stiffness (AS) occur in cardiovascular disease (CVD) patients with SPD. A crosssectional case-control study included hospitalized patients with CVD. Demographic characteristics, CVD and atherogenic risk factors were recorded. SPD was diagnosed by clinical and radiographic dental examinations. Dental clinical attachment level (CAL) and CAL % were recorded. A Mini-Mental State Examination test (MMSE) assessed cognition, a MMSE score of < 27 was set as the cut-off point of CI; a score ≥ 27 was considered as no CI. Patients were categorized into: MMSE<27 (cases) and MMSE≥27 (controls). AS was evaluated by pulse wave velocity (PWV). Serum VCAM-1 levels were determined in a random sample. Results: This study comprised 91 patients (cases, n=26; 29.6%; controls, n=65, 71.4%); aged 73±8 vs. 73±7 years, respectively (p=0.73), of whom 53.8% and 36.9% respectively, were women; SPD was found to be a risk factor for CI; the presence of SPD increased the risk for MMSE <27 by an average 5.39 times (model 1). PWV was associated with MMSE < 27 in the three models. The risk of having MMSE < 27 increased an average of 2.404-fold for each 1-unit increase in PWV. SPD and AS had significant and independent associations on the risk for development CI. MMSE negatively correlated with CAL% (r=0.69) and PWV (r=0.70). PWV positively correlated with CAL% (r=0.67). Serum VCAM-1 levels were higher in SPD with lower MMSE scores. In conclusion, SPD increases the risk of development of cognitive decline in CVD patients. PWV was directly associated with the risk of cognitive decline. These findings denote a significant opportunity to improve periodontal health in order to avert CI in CVD patients.","PeriodicalId":7033,"journal":{"name":"Acta odontologica latinoamericana : AOL","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82902501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to evaluate the dental use of bone grafts according to the perception of dentists in the city of Sobral, Brazil. We interviewed 183 professionals and analyzed their professional data, knowledge of the subject, specific use, and opinions on cost-effectiveness and biosafety. Most of the respondents had 10 years' or less experience in the profession, and lacked specialization though they had been familiar with the subject since they graduated. The most frequently mentioned compositions were ceramics, followed by composites. Only a quarter of the respondents had performed bone grafts, generally with up to 50 cases, with the most frequent applications being using simultaneously with a dental implant, fresh dental sockets and maxillary sinus lifting. Autogenous and xenogeneic grafts were more frequent than alloplastic and allogeneic; ceramics were the most frequently used composition, and the association of bone graft with membrane was more frequent than bone graft alone or associated with autologous fibrin. Professional and patient satisfaction was high, cost was considered moderate, and differences were found regarding patient participation in the choice and country of origin of the product. Bone grafts were used more often in the private than public service. Dentists stated that they follow the instructions. Inflammatory or infectious complications were found to be related to the frequency of the procedure performed and safety regarding the origin. Opinions were favorable regarding the use of grafts derived from animals and unfavorable to grafts derived from cadavers. Very few respondents were registered in human bone tissue banks.
