The maintenance of adequate fluoride (F) concentration in the public water supply is fundamental for ensuring that the community use of F can reach the maximum benefit for caries control and minimum risk for dental fluorosis. Thus, surveillance systems must use accurate and valid analytical methods to determine F concentration and, according to the literature, give preference to the ion-specific electrode (F- ISE) analysis. Aim: The objective of this study was to compare the accuracy of the ISE and SPADNS methods in the determination of the F concentration in the same water sample. Methods: Duplicate water samples were taken from 30 sampling sites in the municipality of Maringá, state of Paraná, monthly for 12 months, totaling 276 samples. An aliquot was analyzed by the FOP-UNICAMP Oral Biochemistry laboratory, using the F- ISE method, and the other one, by the SANEPAR laboratory in Maringá/PR, using the SPADNS method. Descriptive analysis and Pearson’s correlation test were applied, with a significant level of p<0.05. Results: Results were expressed as ppm F (mg F/L), and a very strong positive correlation (r= 0.91; p<0.001) was detected between the two methods of analysis. Conclusion: Our findings suggest that the determination of f luoride concentration in water can be made with accuracy by the SPADNS method, a standardized analysis protocol.

Aim: to evaluate the occurrence of maxillofacial infection cases, which were treated at local hospital, identifying the main risk factors that determine the need for hospitalization of patients and the factors associated with staying length. Methods: A retrospective review of 191 records of patients with maxillofacial infection of odontogenic origin was performed, statistically evaluated by frequency and percentage of involvement, p values (based on the chi-square test) and odds ratio with a 95% confidence interval. A p-value <0.05 was considered statistically significant. Results: Among all the 191 patients, 31 had some harmful habits, such as smokers (13%) and alcoholics (1%). In addition, 39 patients reported some general health problem, such as systemic arterial hypertension (8.3%), depression (6.8%), diabetes (3.6%) and some immunosuppression (1.57%). Involvement of infection in deep facial spaces was present, with 119 patients presenting a deeper infection (62.3%) and 72 patients a superficial infection (37.7%). The most prevalent clinical signs and symptoms in the initial evaluation were pain (91.1%) and edema (90.1%), followed by erythema/hyperemia (44.5%), trismus (37.7%), abscess (30.9%), cellulitis (27.7%), f istula (16.8%), fever (16.8%), dysphagia (11%), dehydration (9.9%), odynophagia (7.9% ) and dyspnea (3.7%). Pulp necrosis was considered a risk factor for treatment in a hospital environment (0.032) and root canal treatment decreases the risk of hospitalization (p=0.002). Considering the evaluated patients, 146 (76.4%) were admitted and 45 (37.7%) were not admitted for hospitalization after initial clinical evaluation. Conclusion: there is a high occurrence of maxillofacial infection cases of dental origin, considering that involvement of infection in deeper facial spaces, as well as presence of pain, edema, erythema/hyperemia, trismus, abscess, cellulitis and pulp necrosis, represent the main risk factors for hospitalization and staying length.

Aim: Venous blood derivatives (VBDs) have been suggested as substitutes for Fetal Bovine Serum (FBS) to improve the clinical transition of cell-based therapies. The literature is not clear about which is the best VBDs substitute. The present study aimed to evaluate the influence of VBDs on cell viability and describe a new method to seed these cells in a 3D Platelet-Rich Fibrin (PRF). Methods: Blood was processed to obtain Platelet-Poor Plasma from PRF (P-PRF), Human Serum (HS), Platelet-Poor Plasma from PRP (P-PRP), activated-PRP (a-PRP), and Platelet lysate (PL). Cells were supplemented with each VBD at 10% and FBS at 10% was the control. Cell viability (fibroblast 3T3/NIH) test was evaluated with MTT assay in two ways: i) cell-seeded and expanded with VBD; ii) cell-seed with FBS and expanded with VBD. To seed the Fibrin construct, cells were suspended in PBS and dropped into the blood sample before performing Choukroun’s protocol for PRF. Constructs were cultured for 7 days in VBD supplements and FBS. Histological and Immunohistochemical analysis with vimentin was performed. Cell viability was analyzed by one-way ANOVA. Results: VBD’s production time was very heterogeneous. Cells expanded in HS and a-PRP has grown faster. VBD-supplemented culture media provided cell culture highly sensible to trypsin/EDTA 0.25%. Cells seeded and expanded with VBD presented viability comparable to FBS in HS, a-PRP, and P-PRP (p>0.05) and lower in P-PRF and PL groups (p<0.05). The viability of cell seed with FBS and expanded with VBD was similar between P-PRF, a-PRP, PL, and FBS (p>0.05) and lower in HS and P-PRP (p<0.005). PRF-seeded cells showed a positive expression of vimentin and were able to maintain all cells supplemented with VBD. Conclusion: VBD supplements were able to maintain fibroblast cells in 2D and 3D cultures. The new method of the fibrin-cell construct was efficient to insert the cells into the fibrin network.

Aim: This present study aims to compare the data from the Brazilian Unified Health System on the number of clinical consultations of Oral Medicine from the first 6 months (March-August 2020) of the COVID-19 pandemic in Brazil with the last 6 months (September-February 2020/2021) to update the data, verify the measures’ effectiveness to return clinical activities in the following months. Methods: perform a literature review of recent articles that report the impact of the COVID-19 pandemic on Oral Medicine. Results: There was an increase in the number of Oral Medicine clinical consultations in the second half of the pandemic throughout Brazil (+64.2%), representing over 9,235 appointments in this period. Conclusion: measures for the return of health assistance and the practice of Telemedicine proved to be effective after the second period of the pandemic. Even so, strengthening security measures against the coronavirus is essential to ward off a new wave since the Omicron variant emerged in the country and, consequently, possible new lockdowns that might affect healthcare in Brazil.

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy.

Aim: This study aimed to compare the influence of sodium hypochlorite (NaOCl) and calcium hypochlorite [Ca(OCl)2 ] on the apical sealing capacity of AH Plus (Dentsply Maillefer) and Bio-C Sealer (Angelus) endodontic sealers. Methods: Sixty permanent human lower incisors were randomly allocated (http://www.randomized.org), according to the irrigant used, into three groups (n=20): 0.9% sodium chloride (NaCl/Control); 2.5% NaOCl; and 2.5% Ca(OCl)2 . The root canal was prepared with rotary files under 10 mL of the solution corresponding to the experimental group. Each group was subdivided into two (n=10) according to the sealer used for filling: AH Plus (Dentsply Maillefer) or Bio-C Sealer (Angelus). Then, all samples were immersed in black India ink for one week. After the storage period, the roots were then grooved longitudinally and split, and the ink penetration was measured from the apical part to the coronal part of the root canal into which the ink penetrated using a stereomicroscope. Data were analyzed by one-way ANOVA and Tukey’s post-hoc tests. Results: There was no statistical difference in ink penetration between the different endodontic sealers tested for the same irrigating solution (p > 0.05). However, when the Bio-C Sealer (Angelus) was used, the group treated with 2.5% Ca(OCl)2 was associated with lower values of apical leakage, compared to 2.5% NaOCl (p < 0.05). For the AH Plus sealer (Dentsply Maillefer), there was no difference between the irrigants (p > 0.05). Conclusions: Associating Ca(OCl)2 irrigant with Bio-C Sealer (Angelus) seems to be a good option to reduce apical leakage.

Aim: With the significant increase in life expectancy over the last decades, it is important to understand how oral health can impact the oral health-related quality of life of older adults. This study aimed to investigate the association between need to replace dentures and oral health-related quality of life (OHRQoL) among older adults belonging to a Cohort in southern Brazil. Methods: This cross-sectional study was conducted with data from the 2019 Pelotas Elderly Cohort. The OHRQoL was assessed using the GOHAI. Need to replace dentures was self-report using a question dichotomized into yes/no. In the statistical analysis, unadjusted and adjusted models estimate from linear regression models were calculated. The significance level adopted was 5%. Results: A total of 493 older adults were included. On the GOHAI questionnaire, the mean score was 32.74 (SD±0.16). Individuals considering need of prosthesis replacement were 47.89%. Report of need to replace dentures was associated to lowest mean on the GOHAI score (β -1.14; 95%CI - 1.80; -0.478, and on the physical (β -0.56; 95%CI - 0.94 -0.17) and psychosocial (β -0.48; 95%CI - 0.74; -0.22) dimensions. Conclusion: Our findings highlight the importance of also considering subjective measures of oral health in the dental care of older adults, since reporting the need for denture replacement, regardless of the reason, was associated with a worse oral health-related quality of life, including physical and psychosocial aspects.

Aim: To assess the opinion of the students on the impact of COVID-19 pandemic on theoretical knowledge and clinical practice in dentistry at the Piracicaba Dental School – FOP/UNICAMP. Methods: A questionnaire was applied using the Google Forms platform, containing 20 questions related to the impacts of the pandemic on knowledge, mental health, and clinical and laboratory practice of dentistry. The satisfaction of the students with teaching was also evaluated. A total of 120 questionnaires were analyzed using R software, through tables and graphs of absolute and relative frequencies distribution. Results: COVID-19 affected the lives of 99% students who participated in the study. Due to distance learning resulting from the COVID-19 pandemic, 50% of the students considered locking or dropping out of college. Operative dentistry was the curricular component most affected by distance and lack of clinical practice. Although most students agreed that the workload of practical disciplines was or would be replaced, 95% felt some kind of deficit in clinical and laboratory practice even with the replacement of the workload. In addition, 93.3% of the students were afraid of not becoming a qualified professional due to the deficiencies on theoretical knowledge and clinical practice caused by the pandemic. Conclusions: Students showed dissatisfaction with the deficiency of clinical and laboratory practice resulting from the pandemic in operative dentistry curricular component. They reported fear and insecurity with their future professional lives. The indication of remote classes for dentistry should only be carried out in emergencies because this is an essentially practical course that suffers losses in learning.

Aim: Like other fields of health, the main focus in dentistry has shifted from treatment to prevention of diseases. Parents have a vital role in deciding about their children’s oral health issues. This study aims to investigate the effectiveness of four educational methods (including printed pamphlets, digital pamphlets, faceto-face education, and educational films) in increasing the awareness of parents about preventive orthodontic treatments. Methods: The study samples were selected from patients who were referred to the Pediatric Dentistry Department. 150 parents of children between 4-12 years old participated in the study. They filled out a questionnaire including demographic data and knowledge about orthodontic problems and their early treatments. Then they were divided into five groups (control, printed pamphlet, digital pamphlet, face-to-face, educational films) and after one month they repeated the test. Results: A total of 102 fathers and 48 mothers were evaluated. There was no statistical difference between different ages, sex, or income in terms of their awareness, but the awareness score between educational groups was different. There has been observed a significant increase in the awareness level of all four groups (except the control group) (P < 0.05). The highest score was seen in the video group. The difference between printed pamphlets and digital pamphlets was not significant. Conclusions: The results indicate that educational films are the most effective way of increasing awareness about preventive orthodontic treatments.

Aim: To evaluate the surface roughness and color stability of bulk-fill resin composites after simulated toothbrushing with whitening dentifrices. The radioactive/relative dentin abrasion (RDA) and radioactive/relative enamel abrasion (REA) of dentifrices were also assessed. Methods: Specimens (n=10) of Tetric N Ceram Bulk Fill (TNCB), Filtek One Bulk Fill (FOB) resin composites, and Z100(Control) were prepared using a cylindrical Teflon matrix. Surface roughness (Ra, μm) was assessed by a roughness meter and the color evaluations (ΔEab , ΔE00 , WID ) were performed using a digital spectrophotometer based on the CIELAB system. Three measurements were performed per sample, before and after simulated toothbrushing with 3D Oral-B White Perfection (3DW) and Black is White (BW) dentifrices. The abrasivity (REA and RDA values) of the used dentifrices was also determined by the Hefferren abrasivity test. Results: The Ra values increased significantly in all resin composites after 3DW and BW toothbrushing. The acceptable threshold color varied among resin composites, and TNCB and Z100 presented the highest ΔEab and ΔE00 for BW dentifrice. The 3DW dentifrice was significantly more abrasive than BW dentifrice on enamel and dentin. Conclusions: simulated toothbrushing with tested whitening dentifrices increased the surface roughness at acceptable levels. The Tetric N Ceram Bulk-fill and Z100 composite showed the highest color alteration in BW. 3D White Perfection dentifrice was more abrasive on dentin and enamel than Black is White.
目的：评估使用美白牙膏模拟刷牙后，大量填充树脂复合材料的表面粗糙度和颜色稳定性。此外，还评估了牙膏的放射性/相对牙本质磨耗（RDA）和放射性/相对釉质磨耗（REA）。方法使用圆柱形聚四氟乙烯基质制备 Tetric N Ceram Bulk Fill (TNCB)、Filtek One Bulk Fill (FOB) 树脂复合材料和 Z100（对照）的试样（n=10）。表面粗糙度（Ra，μm）由粗糙度仪评估，颜色评估（ΔEab、ΔE00、WID）由基于 CIELAB 系统的数字分光光度计进行。在使用 3D Oral-B White Perfection (3DW) 和 Black is White (BW) 牙膏进行模拟刷牙前后，对每个样本进行了三次测量。所用牙膏的磨蚀性（REA 和 RDA 值）也是通过 Hefferren 磨蚀性测试确定的。结果显示刷牙 3DW 和 BW 后，所有树脂复合材料的 Ra 值都明显增加。不同树脂复合材料的可接受阈值颜色各不相同，TNCB 和 Z100 的 ΔEab 和 BW 牙膏的 ΔE00 最高。3DW 牙膏对牙釉质和牙本质的磨损性明显高于 BW 牙膏。结论：使用测试过的美白牙膏进行模拟刷牙会增加表面粗糙度，达到可接受的水平。Tetric N Ceram Bulk-fill和Z100复合材料在BW中的颜色变化最大。与黑即白相比，3D 完美白牙膏对牙本质和珐琅质的磨损更大。
