Introduction: The importance attached to ethical practice and related informed consent varies among health professionals and is further influenced by working environments, level of knowledge, experience and societal values and beliefs. The objective of this study is to evaluate the ethical conduct of professors, undergraduates and graduate students through questionnaires answered by patients. Methods: One hundred twenty (120) patients at the dental clinics of three different dental schools in São Paulo State were interviewed based on objective and discursive questions about signed informed consent, participation in scientific research, photographs during treatment, requested saliva samples, tooth donation requests, and information about tooth destination after removal. A frequency distribution (absolute and percentage values) was used for a statistical analysis of the data. Results: In all, 65.8% of the patients had given signed informed consent for treatment and 12.5% had not done so; 10.8% did not know if they had participated in scientific research; 54.2% were photographed during dental procedures and 47.1% of them had signed an authorization form; 6.6% were requested to provide a saliva sample and 66.6% of them had signed an authorization form to that effect; 16.1% had a tooth donation requested and 64.4% of them had signed an authorization form to that effect; and 61.3% did not know the destination of the tooth after removal, when donation was not requested. Conclusions: The majority of the patients had signed an informed consent form for treatment, photographs, saliva samples and tooth donation. This demonstrated ethical conduct towards patients on the part of professors, undergraduates and graduate students. [ABSTRACT FROM AUTHOR]

Aim: To analyze the dental arches by occlusal radiographs for possible gender differentiation. Methods: One hundred occlusal radiographic images were obtained. First, a median line and a line touching the vestibular portions of the projections of the maxillary central incisors were drawn. The intersection of these lines was called point I and from this point a line to the canine most vestibular portion was drawn, from the second premolar and second molar, from the left and right sides, in the maxillary and mandibular arches, thus obtaining the angle measurements. Line measurements relative to the width of the arches in three segments, canines, premolars and second molars were made. Results: The analyses performed by t-test indicated that all linear values obtained were statistically different (p<0.05), as may be seen in the values obtained from canine to canine, in which the female average was 3.48 cm (0.16) while the male average was 3.74 cm (0.21) and in respect to the angle measurements, only two angles have shown applicability in the definition of gender. Conclusions: Gender can be determined by analysis of occlusal radiographs with greater reliability when linear measurements are performed. [ABSTRACT FROM AUTHOR]

Background: The oral cavity harbors more than 700 species of bacteria, which play crucial roles in the development of various oral diseases including caries, endodontic infection, periodontal infection, and diverse oral diseases., Aim: To investigate the antimicrobial action of Cymbopogon Schoenanthus and Pelargonium graveolens essential oils against Streptococcus mutans, Staphylococcus aureus, Candida albicans, Ca. dubliniensis , and Ca. krusei ., Methods: Minimum microbicidal concentration was determined following Clinical and Laboratory Standards Institute documents. The synergistic antimicrobial activity was evaluated using the Broth microdilution checkerboard method, and the antibiofilm activity was evaluated with the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay. Data were analyzed by one-way analysis of variance followed by the Tukey post-hoc test ( P ≤ 0.05)., Results: C. schoenanthus and P. graveolens essential oils were as effective as 0.12% chlorhexidine against S. mutans and St. aureus monotypic biofilms after 24 h. After 24 h P. graveolens essential oil at 0.25% was more effective than the nystatin group, and C. schoenanthus essential oil at 0.25% was as effective as the nystatin group., Conclusion: C. schoenanthus and P. graveolens essential oils are effective against S. mutans, St. aureus, Ca. albicans, Ca. dubliniensis , and Ca. krusei at different concentrations after 5 min and 24 h., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest to declare., (©The Author(s) 2024.
