ABSTRACT Objective: Evaluated the antifungal effect of the incorporation of different concentrations of the essential oil Cymbopogon citratus (capim santo), into polymethylmethacrylate (PMMA) against Candida albicans. Methods: Fifty specimens were fabricated and divided into five groups: Group 1, PMMA + 10% essential oil (n=10); Group 2, PMMA + 15% essential oil (n=10); Group 3, PMMA + 20% essential oil (n=10); Group 4, PMMA + 25% essential oil (n=10); Group 5, PMMA (n=10). PMMA powder was mixed with the monomer and the mixture was placed in disc-shaped cavities measuring 15 mm in diameter, 2 mm thick. To evaluate the antifungal activity of the experimental specimens, the standard strain of Candida albicans was tested. After incubation, the colony count of each plate was performed using a digital colony counter, obtaining the number of colony forming units (CFU) and the Kruskal-Wallis test was applied. Results: There was statistically significant difference in the CFU count of Candida albicans as a consequence of the addition of Cymbopogon citratus essential oil to PMMA (p < 0.001) and values were significantly higher in comparison with those of all the other groups, when the essential oil was incorporated as incorporated into the PMMA in the concentration of 20%. In the other concentrations, no difference in values was observed in comparison with the Control Group without essential oil of Cymbopogon citratus. Conclusion: The acrylic resin with the essential oil incorporated into it in different concentrations provided no effect against development of the genus Candida.

ABSTRACT Objectives: The objective was to evaluate the longevity of ceramic restorative materials in the manufacture of endocrown restorations, through an in vitro study on surface roughness and mechanical strength. Methods: Three restorative materials were evaluated and assigned to experimental groups (n=10 disc specimens): Leucite Reinforced Ceramic, Lithium Disilicate and Nanoceramic Resin. These restorative materials were evaluated for surface before and after aging (n=02 specimens) under a stereomicroscope. The specimens were submitted to the average surface roughness test (Ra) (n=10) in a contact roughness meter before and after aging. As well as the biaxial flexural strength test (n=10), after aging, up to a test speed of 0.5 mm/min. Aging was carried out in a thermocycler, with 5,000 cycles with baths of 5 °C ± 1 ° and 55 °C ± 1 °. Fragments after fracture were observed under a stereomicroscope. The data obtained were tabulated and analyzed using the Minitab statistical program. Results: The surfaces of the specimens do not show changes between the restorative materials and also in relation to aging. For the roughness data, the restorative material factors (p=0.867) and aging (p=0.321) were not statistically significant. The DIS group presented the highest values of fracture resistance (p=0.000), in relation to the LEU and REN groups, which were statistically similar. The same statistical pattern was identified for post-fracture fragment data (p=0.030). Conclusions: The aging factors and restorative material do not interfere with the surface roughness performance. However, the mechanical performance and number of fragments after fracture is affected by the restorative material.

ABSTRACT Objective: radiotherapy can lead to different adverse effects in the oral epithelial cells. This article aimed to address the main oral manifestations associated with radiotherapy of head and neck neoplasms, highlighting the importance of the dental practitioners’ participation within the skilled multidisciplinary personnel to treatment. Methods: Research was conducted in the PubMed, Lilacs, SciELO, and Google Scholar databases using the keywords “head and neck radiotherapy”, “oral manifestations’’, and “head and neck neoplasm”. Eighteen out of 533 articles published between 2015 and 2022 were selected after duplicates removal and eligibility criteria application. Results: xerostomia, hyposalivation, trismus, dysgeusia, dysphagia, dentin hypersensitivity, fungal and viral infections, radiation caries, osteoradionecrosis, mucositis, periodontal alterations, and tooth development abnormalities were the most frequently reported oral effects of radiotherapy. Conclusions: The participation of dentists in the multidisciplinary team that treats patients with head and neck cancers is fundamental since several oral complications of radiotherapy are observed. Dentists can prevent, reduce and treat some detrimental effects whether the patient is followed-up since the beginning of radiotherapy.

ABSTRACT Perform a systematic review of the literature to seek scientific evidence on the effect of low-level laser therapy on duration, degree and pain of chemotherapy-induced oral mucositis in young patients with cancer. Methods: A bibliographic search was performed using the PubMed, Scopus and Web of Science databases to identify relevant scientific studies, found through the descriptors “laser therapy”, “phototherapy”, “oral mucositis”, “pediatric patient” and “children” to evaluate this association. Information regarding the degree of mucositis, pain associated with patients, toothbrushing and laser were analyzed characteristics. Results: Of the nine studies, one did not obtain significant results on the healing action of LLLT on oral mucositis and of the eight remaining studies, 83. 3% showed significant evidence of a decrease in the degree of oral mucositis and consequently its duration. With regard to pain, 100% of the studies confirmed its decrease. Conclusion: Low-level laser therapy is considered an efficient instrument for the treatment of oral mucositis on young patients with cancer due to its analgesic, anti-inflammatory and healing effects.

ABSTRACT Objective: Study the prevalence of burnout and the salivary biomarkers in military police officers in the São Paulo health-care team who worked during the Covid-19 pandemic in Brazil. Method: An observational cross-sectional study was conducted in a sample of 104 participants distinguished by age, skin color, gender, military rank, function performed, length of service, use of medications, smoking, alcohol consumption, and income. The analysis of the social demographic data collected used an adapted Maslach Burnout Inventory and saliva examination through Fourier transform infrared spectroscopy. The statistical tests of chi-square, PLS-DA, and hypothesis were fixed at the 95% confidence. Results: The social demographic indicators presented statistical association with burnout, with chi-square 62.72 (p<0.05). The prevalence of burnout (80.77%) and risk of development (19.23%) were observed. The presence of biomarkers in saliva (amide, genetic fragments and polysaccharides) in those experiencing burnout aligned with current literature. Conclusion: Of the total sample, 80.77% had burnout and 19.23% risk of developing the disease. Young white women, in the role of health assistants, with median income between 3 and 6 times the minimum wage and with less than 10 years of service`s length had the highest prevalence of burnout in relation to their peers. There was an association of social demographic indicators with measured stress levels. Salivary biomarkers were also associated with stress in the initial phase of burnout. There is a pressing need for further studies, aiming to support greater knowledge for this population researched.

ABSTRACT Objective: To evaluate the role of music as a distraction technique to minimize anxiety during dental care in children aged 7 to 9 years when submitted to local anesthetic procedure. Method: This study was carried out in the Dentistry Module of the State University of Southwestern Bahia, located in the city of Jequié, Bahia, Brazil. It was performed through the application of the Facial Image Scale, measurement of heart rate and blood pressure with the aid of the digital sphygmomanometer at two different times during pediatric dentistry care with and without the influence of classical music. Data were tabulated in the Statistical Package for Social Sciences software, version 21.0, expressed as medians and interquartile range. For inferential statistics, the Shapiro-Wilk normality test was used and the analysis of the effect of music was calculated using the paired T-tests and Wilcoxon, considering a significance level of 95%. Results: The sample consisted of 7 children, mostly male, with a median of 8 years of age. Regarding the psychophysiological variables, no significant variations were observed compared to before and after in the groups with music and without music. Conclusion: In this study, no differences were found regarding the reduction of anxiety in the group in which music was used. Additional studies with a representative sample are needed.

ABSTRACT Objective: To identify the lingual foramina in a Brazilian population of 210 individuals through Cone-Beam Computed Tomography images, in order to guide the installation of dental implants in the region of the mental symphysis. Methods: After identifying the lingual foramina on a parasagittal section, four measurements were taken: distance to the alveolar ridge, distance to the mandibular lower border, distance to the limit of the vestibular cortical, and alveolar ridge inclination angle. The measurements were compared in relation to gender by the Mann-Whitney test. The association between gender and the number of foramina was done by the chi-square test. Pearson’s correlation analyzed the linear relationship between age and number of foramina. Results: Lingual foramina are present in 99.6% of the research participants. In the upper-inferior direction, a mean distance to the alveolar ridge of 21.4 mm was noted, while the mean distance to the lower mandibular border was 13.1 mm. In the bucco-lingual direction, a mean distance from the lingual foramina to the vestibular cortical of 15.2 mm is noted. The inclination angle of the alveolar ridge had a mean of 25.4º. Regarding gender, the test was not significant only for the distance to the vestibular cortical. Conclusion: The lingual foramina had a descending way in 100% of cases, being positioned mainly in the middle thirds (66.5%) and lower thirds (32.7%) of the mandibular ridge height. The use of dental implants up to 13 mm in length and up to 4 mm in diameter in the region of the symphysis mentualis is recommended.

Methods: After identifying the lingual foramina on a parasagittal section, four measurements were taken: distance to the alveolar ridge, distance to the mandibular lower border, distance to the limit of the vestibular cortical, and alveolar ridge inclination angle. The measurements were compared in relation to gender by the Mann-Whitney test. The association between gender and the number of foramina was done by the chi-square test. Pearson’s correlation analyzed the linear relationship between age and number of foramina. Results: Lingual foramina are present in 99.6% of the research participants. In the upper-inferior direction, a mean distance to the alveolar ridge of 21.4 mm was noted, while the mean distance to the lower mandibular border was 13.1 mm. In the bucco-lingual direction, a mean distance from the lingual foramina to the vestibular cortical of 15.2 mm is noted. The inclination angle of the alveolar ridge had a mean of 25.4º. Regarding gender, the test was not significant only for the distance to the vestibular cortical. Conclusion: The lingual foramina had a descending way in 100% of cases, being positioned mainly in the middle thirds (66.5%) and lower thirds (32.7%) of the mandibular ridge height.

ABSTRACT In Brazil, the estimated number of new cancer cases between 2020 and 2022 is 625 thousand, and the most prevalent carcinomas are primarily skin (non-melanoma), followed by those of the breast, prostate, colon, and rectum. Although breast carcinoma still has a high mortality rate, it has a good prognosis due to the increase in early diagnosis and the evolution of anticancer treatments. The proposed treatment can be isolated or associated with resective surgery, radiotherapy, chemotherapy, and/or hormone replacement. Chemotherapy generates extensive immunosuppression and affects both healthy and altered cells, and the cytotoxicity of the treatment is an important effect that can cause lesions on the oral mucosa. Severity is related to the type of chemotherapeutic agent, treatment time, the dose used, and the individual’s age. Additionally, chemotherapy treatment can exacerbate preexisting conditions in the individual and cause greater discomfort during treatment. Therefore, monitoring oral health before, during, and after anticancer therapy is essential. The objective of this work is to report a clinical case of dental emergency in a patient after the first cycle of doxorubicin- cyclophosphamide-paclitaxel (ACTdd) to treat breast cancer.

ABSTRACT SARS-CoV-2 is caused by an RNA virus responsible for the disease known as COVID-19. First diagnosed in 2019, in a human being in the city of Wuhan, China, this disease is classified as a severe respiratory disease. Propagation occurs through coughing, sneezing, inhalation of droplets, or even indirect contact with the nasal, oral, and ocular mucous membranes. Preventive measures involving social distancing, quarantine, and mask use were implemented to prevent its spread. Such measures challenge dental practices, since they depend on proximity and do not allow the use of personal protective equipment, which cover the patient’s oral cavity. This integrative literature review sought to identify articles discussing preventive measures of adequate use in current dental practices, reducing the risk of COVID-19 contamination and spread. Results showed the importance of dentists acting on the disease transmission routes, following care protocols, implementing new dental clinic management practices, such as avoiding crowds, longer time between appointments, use of teledentistry, and adopting preventive measures inside the dental office like hand washing, use of N95 mask, face shield, and air filters. However, oral health professionals must be prepared to face any imminent challenge imposed by infectious diseases in dental practice, following protocol before, during, and after dental care.
