ABSTRACT Objective: To assess dentists' knowledge from Minas Gerais, Brazil, about dentoalveolar trauma (DT) and their experiences during the COVID-19 pandemic. Material and Methods: An online questionnaire with 34 questions was applied to collect personal data, professional training, self-assessment of experience/knowledge about DT, experience in care provided during the social distancing, and knowledge/conduct. The specific responses were evaluated based on the guidelines of the International Association of Dental Traumatology (IADT). Descriptive analysis and Pearson's chi-square test were performed. The level of significance was set at p≤0.05. Results: Most professionals (97.7%) had received information on DT, and only 4.6% of the participants considered their knowledge poor or very poor. However, 92.7% felt the need for more information on the subject. Regarding experiences during the pandemic, 55.7% provided trauma care during that period. Forty percent of the consultations were performed in person, and 33.3% of the professionals noted an increase in cases during the pandemic; 56.6% reported that the frequency did not change. The overall mean number of correct answers about DT was 5.29±2.11, indicating an acceptable level of knowledge. The mean percentage of hits for the specific questions was 44.1%. Conclusion: Although the level of knowledge of the dentists evaluated was acceptable, some aspects were deficient, with the need for more information about the IADT guidelines.

ABSTRACT Introduction: The removal of residual resins is a routine procedure in orthodontic clinics and of great importance to the final result of the treatment. Objective: To evaluate the main methods of residual resin removal used by orthodontists, and the main reasons for choosing these methods. Methods: A questionnaire consisting of 21 questions: 6 relating to demographic data and the other 15 relating to two methods used to remove residual resins (drills or pliers) was sent by e-mail to orthodontists registered with the Regional Councils of Dentistry of São Paulo and Rio de Janeiro (Brazil) within April and June, 2023. Questionnaires were sent back by 153 professionals. Results: Residual resin removal is always carried out with high speed drill for 44.7% of the sample, and with low speed drill for 28.7%; 61.3% use irrigation. The multi-laminate carbide bur is used by 82.5% of orthodontists. Pliers are always used by 12.4%. Resin-removing pliers with Widia are used in 39% of cases. The use of high speed was justified by the shorter working time, and the choice of pliers was justified by the smaller damage to the tooth enamel. Conclusion: The most used residual resin removal method was the multi-laminate carbide bur at high speed with irrigation, justified the by shorter working time.

Abstract The consequences of traumatic dental injuries can be even more serious when their emergency management procedures are inadequate. Since traumatic accidents frequently occur at school, it is crucial that teachers be knowledgeable enough to assist an injured child. This study aimed to assess the knowledge and attitudes of the elementary school teachers of a Brazilian city toward dental trauma in permanent teeth, and its emergency practices. A combination of convenience and snowball sampling methods was used. An online questionnaire was distributed through social media, consisting of three parts: demographic characteristics and professional information; previous experiences and attitudes toward dental trauma; teachers’ knowledge of this subject. Descriptive and statistical analyses were carried out. Pearson chi-squared test (p < 0.05) was used. A total of 217 teachers participated in the study. The power of the sample was 95%. Half of the teachers had already witnessed a dental trauma incident involving students, and 70.5% never received any information on the subject. The teachers who were provided previous information were the ones who opted to search for the tooth fragment (p=0.036) in cases of crown fracture, and for the lost tooth (p = 0.025) in cases of avulsion. They were also the ones who chose to wash the tooth in running water (p = 0.018), and look for a dentist in the first 30 or 60 minutes after the trauma (p = 0.026). Most of the teachers assessed did not have adequate knowledge of dental trauma. Having previous information was associated with more assertive practices in trauma management. inadequate child teeth used media parts subject out chisquared chi squared p 0.05 005 0 05 21 95 95% students 705 70 5 70.5 p=0.036 p0036 036 (p=0.036 fracture 0.025 0025 025 avulsion 0.018, 0018 0.018 , 018 0.018) 3 6 0.026. 0026 0.026 . 026 0.026) 0.0 00 2 9 7 70. p=0.03 p003 03 (p=0.03 0.02 002 02 001 0.01 01 0. p=0.0 p00 (p=0.0 p=0. p0 (p=0. p=0 (p=0 p= (p=

Abstract The social isolation measures adopted during the critical phase of the COVID-19 pandemic led children to spend most of their time at home. Isolation may alter the pattern of traumatic dental injury occurrences, inasmuch as studies point out that most traumatic accidents occur at home. Considering this scenario and the influence of emergency management on the prognosis of the injury, the aim of this study was to evaluate the experience of traumatic dental injuries in children before and during the pandemic, and the knowledge of this topic by the children’s guardians. This cross-sectional study was conducted with guardians of children aged 0 to 6 years, residing in Juiz de Fora, MG, Brazil. The guardians answered an online questionnaire addressing personal information, traumatic dental injury experience before and during the pandemic, and knowledge of this topic. Descriptive and statistical analyses were performed using Pearson’s chi-square test at a 5% significance level. The total sample consisted of 343 volunteers. A total of 95 and 92 injuries were reported before and during the pandemic, respectively; the home was the place of greatest occurrence. Most volunteers (88.1%) agreed that traumatic dental injuries are emergency situations, and were aware that the tooth/fragment had to be taken to the dentist after a fracture or avulsion (97.4%). This study revealed that the traumatic dental injury experience was similar before and during the pandemic, and that the volunteers had satisfactory knowledge, especially in recognizing the importance of immediate attention for a more favorable prognosis of these injuries.

ABSTRACT Objective: To assess the knowledge of undergraduate health care students, about avulsion of permanent teeth. Material and Methods: It is a cross-sectional study. The sample consisted of Brazilian undergraduate students of the nursing, medicine, and dentistry degree programs. A structured questionnaire developed by the researchers, containing 18 objective questions about avulsion of permanent teeth was used as the data collection. Data analysis included Pearson's Chi-square and Fisher's Exact. Results: A total of 82.7% dental students, 22.9% nursing students, and 23% medical students had previously received some information about dental trauma. Students in the second half of the dentistry program had a higher percentage of correct answers in all questions (p<0.05). Being in the first or second half of the nursing program had no relation to the percentage of correct answers by students for any questions (p>0.05). Students in the first half of the medical program had a higher percentage of correct answers for six of these questions (p<0.05). Dentistry students had the highest percentage of correct answers in all the questions (p<0.001). Conclusion: Although students from the dentistry degree program report having information on avulsion of permanent teeth, their practical experience was considered low. Upon comparing students from the dentistry, nursing, and medical degree programs regarding their learning about avulsion of permanent teeth, dentistry students had greater knowledge on the subject.

ABSTRACT Objective: To assess the association between dental caries experience, severe dental caries experience and socioeconomic determinants on oral health-related quality of life among children and their families. Material and Methods: This is a cross-sectional study whose sample was composed of children aged 4-12 years, who sought dental care in a dentistry school clinic, and their parents/caregivers. Dental caries experience and severe dental caries experience were assessed according to the DMF-T/dmf-t indexes. Parents/caregivers answered the Parental-Caregiver Perceptions Questionnaire (P-CPQ), the Family Impact Scale (FIS) and a questionnaire on socioeconomic and demographic conditions. Data analysis included the chi-square test and Poisson regression (PR). Results: The sample was composed of 105 children and their parents/caregivers. Severe dental caries experience in children was determinant for negative perception of children's OHRQoL by parents/caregivers (PR = 1.22; CI = 1.05-1.41). Negative impact on OHRQoL perceived by family members was determined by severe dental caries experience in children (PR = 1.22; CI = 1.05-1.42) and family income <5 minimum wage (PR = 1.32; CI = 1.08-1.61). Conclusion: Severe dental caries experience was associated with a negative impact on OHRQoL perceived by children and their families. Low family income was associated with a negative impact on the OHRQoL perceived by children and their families.

Objective: To evaluate the best strategy for pacifier disinfection methods. Material and Methods: The literature search was conducted on MEDLINE/PubMed, Scielo, Lilacs, Web of Science, and Scopus databases to find all relevant articles published over the past 20 years, based on PRISMA guidelines. Two reviewers extracted data independently by using a standardized form. The following factors were recorded: country of study, type of study, pacifier material, sample number, microorganisms analyzed, decontamination methods used, method accessibility and results found. Results: A total of 121 articles were obtained from all databases. The selected documents underwent a final screening, resulting in 8 articles. The method of disinfection analyzed by the literature were: 3.5% neutral detergent, apple cider vinegar 70% spray, boiling water during 15 minutes, sodium hypochlorite 2.5, hydrogen peroxide 70% spray, chlorhexidine 0.12%, Brushtox®, sterile water and microwave. Conclusion: Because of the broad methods for pacifier disinfection and different levels of accessibility to disinfectant agents, the pacifier consensus for decontamination remains unclear. Although the disinfection methods are diverse, the methods suggested to its disinfection were identified and described in this article.

Abstract Information about bacterial diversity, such as the number of each species in the root canals of primary teeth, contributes to improving our effective management of infections of endodontic origin in primary teeth. This study made a qualitative and quantitative assessment of the bacteria in the root canals of primary teeth with necrotic pulp, using the fluorescence in situ hybridization (FISH) technique. Thirty-one primary teeth with pulp necrosis from 31 children were evaluated using the FISH technique, to detect the presence and density of Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Enterococcus faecalis, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens, Streptococcus, Streptococcus mutans, Streptococcus sobrinus, Tannerella forsythia and Treponema denticola. Descriptive measures explained the data related to density, and Student’s t-test assessed the differences among the densities of each bacterium, according to signs and symptoms. The bacterial density was paired and correlated. All bacteria tested were detected and identified in all the samples. The average number of bacterial individuals from each species ranged from 1.9 x 108 cells/mL (S. mutans) to 3.1 x 108 cells/mL (F. nucleatum) (p > 0.05). The sum of the mean counts of each bacterium represented almost 80% of the entire microbial community. Patients with pain had significantly more T. denticola, and those with edema showed a greater density of Streptococcus and P. nigrescens (p < 0.05). This study revealed that all 12 bacteria evaluated were found in all primary teeth with pulp necrosis. There was no predominance among the species studied; all species had a similar number of individuals.

Abstract This study was aimed to provide a longitudinal overview of the subgingival bacterial microbiome using fluorescence in situ hybridization (FISH) technique, in women in the second trimester of pregnancy (between 14 and 24 weeks), and 48 h and 8 weeks postpartum. Of 31 women evaluated during pregnancy, 24 returned for the 48-h and 18 for their 8-week exams postpartum. Probing depth (PD), bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected, and FISH was used to identify the numbers of eight periodontal pathogens. Friedman test was used to compare differences between follow-up examinations, followed by a multiple comparison test for a post hoc pairwise comparison. Clinically, a significantly greater number of teeth with PD = 4–5 mm were found during pregnancy than on postpartum examinations. Microbial analysis showed a statistically significant decrease in cell count over the study period for Prevotella nigrescens. P. intermedia, Campylobacter rectus, and Porphyromonas gingivalis also decrease, although not significantly, and Aggregatibacter actinomycetemcomitans increased. No significant changes were found for Fusobacterium nucleatum, Treponema denticola, or Tannerella forsythia. Our data demonstrate a change in the subgingival microbiota during pregnancy, at least for P. nigrescens.

The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women. This cross-sectional study included 20 pregnant women in their second trimester of pregnancy and 20 non-pregnant women. Probing depth, bleeding on probing, clinical attachment level, and presence of calculus were recorded. Subgingival plaque samples were collected and the FISH technique identified the presence and numbers of Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Campylobacter rectus, Porphyromonas gingivalis, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia and Prevotella nigrescens. The Mann-Whitney U-test was applied to compare the data between the two groups. The mean age, ethnicity, marital status, education, and economic level in both groups were similar. The clinical parameters showed no significant differences between pregnant and non-pregnant women. The numbers of subgingival periodontopathogens were not found to be significantly different between groups, despite the higher mean counts of P. intermedia in pregnant women. Colonization patterns of the different bacteria most commonly associated with periodontal disease were not different in the subgingival plaque of pregnant and non-pregnant women.

O estudo avaliou a adesão a um Programa de Atenção à Saúde Bucal (PASB) por crianças e adolescentes infectados pelo HIV, bem como a atitude de seus responsáveis quanto a cuidados em relação à saúde bucal. Foram entrevistados 58 responsáveis que acompanhavam crianças e adolescentes HIV+ nas consultas médicas de rotina no ambulatório de aids, os quais foram indagados sobre os dados pessoais, adesão ao PASB ou a outros serviços odontológicos e atitudes quanto aos cuidados bucais. Aproximadamente 70% dos responsáveis disseram que a criança participava do PASB; entretanto, 20% delas não retornavam às consultas de prevenção quando solicitadas, e este retorno era menor quando os responsáveis não eram os próprios pais (p=0,036). A adesão desta população ao tratamento odontológico fora do PASB foi pequena, visto que 48% dos responsáveis relataram que a criança não concluiu o tratamento quando este não foi realizado no PASB. A atitude dos responsáveis em relação aos cuidados bucais das crianças HIV+ também não foi considerada satisfatória. Desta forma, ressalta-se a importância da inserção do odontopediatra em equipes multidisciplinares que atendem crianças e adolescentes HIV+, bem como da divulgação deste serviço para os familiares e para todas as equipes médicas envolvidas com estes pacientes.

This study aimed to evaluate the adherence to an Oral Health Program (OHP) for HIV infected children and adolescents, as well as the attitudes of their caretakers regarding oral care. A total of 58 caretakers that accompany the children in medical appointments at an AIDS ambulatory were interviewed for collecting personal data and data regarding adherence to the OHP or other odontological treatment and attitudes related to oral care. Approximately 70% of the caretakers stated that their children participated in the OHAP, however 20% of them did not return to the recall appointments; such visits were even less frequent when the caretakers were not the parents themselves (p= 0.036). The adherence of this population to dental treatment outside the OHP was small, 48% of the caretakers stated that the child did not conclude the treatment when referred to another place for treatment. The attitude of the caretakers regarding dental care of HIV+ children was not considered satisfactory. Furthermore, it is very important to have pediatric dentists in the multi-professional teams that attend HIV+ children and adolescents and to promote this program among the parents and all medical teams involved with such patients.
