Both isolated mechanical therapy and its association with 0.12% chlorhexidine mouthwash reduced peri-implant mucositis. Therefore, 0.12% of chlorhexidine was not more effective than placebo.
COVID-19: Perspectives for the management of dental care and education The rapid and abrupt transmission pattern of the SARS-CoV-2 unleashed the current COVID-19 pandemic, as recognized by the World Health Organization in March 2020. Considering the high risk of transmission of the virus in dental environments and the specificities in clinical practice, COVID-19 posed immediate challenges for dental care and education. Due to the need to establish infection prevention and control guidance in dental health settings to enable a safe clinical practice, this review aims to list the challenges and perspectives in managing dental care in services and schools. This review employed materials collected from PubMed and the main guidelines and studies on the novel coronavirus to provide an overview of the clinical procedures and decisions made by health care personnel in dental offices and dental schools. We expect the COVID-19 scenario to promote significant changes in clinical practice and dental education; dentists should seek specific and particular regulations for dental practice established by their state or country. Biosafety checklists are strongly recommended for appointments at dental services and face-to-face activities in dental schools.
Peri-implant diseases were diagnosed in 54% of patients; gingival index of greater than 10%, having more than two implants and use of medication were associated with the frequency of peri-implant disease.
Purpose/objectives
To investigate dental students’ perceptions and concerns regarding the COVID‐19 pandemic, their coping strategies and support resources, and their perceived stress levels.
Methods
A customized 19‐item survey and the perceived stress scale (PSS) were applied to undergraduate dental students from the US, Spain, Ireland, Chile, India, and Brazil between April 10 and July 5, 2020. Linear modeling and mediation analysis were used to explore the relationships among demographics, stressors, coping mechanisms, social support, and stress
Results
A total of 4475 students responded to the survey. The majority (72.4%) were women, and 52.3% had no COVID‐19 training at the time of the survey. The students reported that they had to accommodate to changes in patient care (96.6%) and didactic learning (95.2%) activities, while 88.5% of the respondents indicated at least one of their courses moved online. Transition to online courses went “smoothly with some troubles” for 51.8% of the respondents, and 48.3% perceived the faculty as prepared for the online transition; however, 45.9% reported feeling extremely concerned about the impact of COVID‐19 on their education. The average PSS score was 21.9 of 40 (moderate stress). Multivariate models were built for participants with full data (n = 3899). Being male, having completed more dental coursework, and perceiving a smoother transition were associated with lower PSS scores; more concern about academic progress was associated with higher PSS. Faculty support mediated the relationship between a smoothness of transition and concern about academic progress and PSS scores
Conclusion
Stress caused by the pandemic may be alleviated by smoother transition and good faculty support.
ALD may prevent the negative influence of estrogen deficiency on bone healing around titanium implants inserted in OVX rats. This positive effect, in contrast to estradiol, is sustained following its withdrawal.
This research evaluated the fungistatic and fungicidal activities of red propolis alcoholic extract (RPAE) against different Candida species isolated from chronic periodontitis cases, and compared with chlorhexidine (CHX). Nineteen samples of Candida species (C. albicans [n = 12], C. tropicalis [n = 5] and C. glabrata [n = 2]) isolated from chronic periodontitis cases were analyzed. The fungistatic and fungicidal activity of both RPAE and CHX were evaluated using fluconazole and C. parapsilosis (ATCC 6258) as a control. Fungistatic activity was analyzed based on the Clinical and Laboratory Standards Institute (CLSI) reference procedure to determine the minimum inhibitory concentrations. Fungicidal activity was established according to the absence of fungal growth on Sabouraud Dextrose Agar medium. The fungistatic and fungicidal activities of RPAE were observed, respectively, at 32-64 μg/mL and 64-512 μg/mL for C. albicans, 64 μg/mL and 64-256 μg/mL for C. glabrata, and 32-64 μg/mL and 64 µg/mL for C. tropicalis. CHX fungistatic activity was observed at concentrations of 0.003-1.92 µg/mL for C. albicans, 1.92 µg/mL for C. glabrata, and 0.03-1.92 µg/mL for C. tropicalis. Fluconazole fungistatic activity ranged between 1-64 μg/mL, and fungicidal activity occurred at 8-64 μg/mL, for the three Candida species analyzed. All the Candida species were susceptible to RPAE antifungal activity, but five samples of C. albicans, one of C. tropicalis and one of C. glabrata were resistant to fluconazole antifungal activity. CHX showed fungistatic activity against all the Candida species analyzed. The antifungal potential of these substances suggests that they can be applied as an alternative treatment for diseases affected by these species.
BACKGROUNDRecurrent aphthous ulcerations are common benign ulcerated lesions on the
mouth, whose etiology is poorly understood, with controversial treatment and
difficult to control in clinical practice.OBJECTIVETo evaluate the cases of recurrent aphthous ulcerations with a focus on
treatment, diagnosis and etiology.METHODSThis is a retrospective study of the cases of the Oral Diagnosis service of
the Rio Grande do Norte Federal University in Natal/RN. Data such as sex,
age, race, location, smoking habits, types of treatment, relapsing episodes,
laboratory test results and clinical characteristics were collected. The
associations between the variables were analyzed using the Pearson
Chi-square test (p <0.05).RESULTSA total of 4895 patients were seen in the service over a period of 11 years.
Of these, 161 (3.3%) had complaints of oral aphthous ulcerations, of which
76 (47.2%) were diagnosed as suffering from recurrent aphthous ulcerations
and 68 (42.2%) with clinical information necessary for evaluation. The
tongue was the most affected anatomical region, with 27 individuals (39.7%),
followed by the buccal mucosa, with 22 cases (32.3%).STUDY LIMITATIONSRetrospective study with data from medical records.CONCLUSIONDental surgeons, dermatologists and otorhinolaryngologists are the main
responsible for the first contact with patients with this disease and should
be attentive to the clinical aspects and treat each patient in an
individualized way, since the therapy is palliative, its diagnosis is by
exclusion and its etiology is unknown.
