The following descriptors and combinations were used: Parental acceptance OR Parents / psychology AND Child Behavior AND pediatric dentistry OR Dental Care for Children / method. After applying the inclusion and exclusion criteria, a total of 12 articles were studied according to the main objective.Artigo Científico Acesso fechado Ações atuais de escovação supervisionada em crianças: Uma revisão narrativa(2022-06-01) Conceição, EduardaAs ações de escovação supervisionada com crianças são muito utilizadas nas ações de educação e promoção da saúde bucal. Geralmente acontecendo nas escolas, mas também podendo acontecer nos bairros e comunidades, estas ações visam utilizar técnicas e brincadeiras para atrair a atenção das crianças para a higiene bucal e tornar o momento da escovação uma parte importante e divertida da rotina dos pequenos. O objetivo do presente estudo foi analisar o impacto que estas ações de escovação supervisionada têm na vida das crianças, através de uma revisão narrativa. Materiais e métodos: A busca dos periódicos na literatura foi realizada através do uso das seguintes bases de dados: National Library of Medicine (Pubmed) e Scientific Electronic Library Online (SciELO). Os descritores de saúde utilizados estão todos cadastrados no DeCS. Foram aplicados todos os critérios de inclusão e exclusão e a partir disso, um total de 9 artigos foram selecionados para o trabalho em concordância com o objetivo proposto. Resultados: Quando avaliados, 66,6% dos artigos citam sucesso e boas repercussões em ações de escovação supervisionada. Os outros 44,4% dos periódicos, apesar de não citarem diretamente a escovação supervisionada, falam sobre a importância do ensino da escovação durante esta etapa da vida e como ela reflete na saúde das crianças. Conclusão: Quando efetuada com esforço, atenção e cuidado por parte dos profissionais da saúde, as ações de escovação supervisionada causam impactos positivos e podem mudar positivamente a percepção das crianças sobre a odontologia.Artigo Científico Acesso fechado Aleitamento materno e sua importância na odontologia: um estudo com gestantes(2019) Silva, Manoella Medeiros daDespite the increasing dissemination of research relating the benefits of breastfeeding to the general context of the mother-child binomial, studies are still deficient in the emphasis given to the benefits of breastfeeding in relation to the baby's oral health and prevention of malocclusions. The objective of this study was to describe the knowledge of pregnant women attending health promotion groups of Florianópolis Municipal Health Centers, SC, on the importance of breastfeeding under the odontological aspect. It is a descriptive, cross-sectional, quantitative research. The sample consisted of pregnant women. To collect data, a questionnaire was prepared by the authors. The results indicate that among the participants of this study only one does not indicate pretense of breastfeeding. Regarding the knowledge about breastfeeding time and about the benefits of breastfeeding, the majority of pregnant women answered the questions correctly. There were no statistically significant differences in the frequency of correct answers in relation to income and schooling. However, with regard to deleterious sucking habits, there was a difference in the mean age between the groups that matched and those who missed the point. It was possible to verify that pregnant women have knowledge about the benefits of breastfeeding for breastfeeding, which suggests that national investments in breast-feeding campaigns have had positive effects in the community.Artigo Científico Acesso aberto Análise clínica e tomográfica da relação entre o fenótipo gengival e a espessura da tábua óssea vestibular(2018) Kiatkoski, Leonardo GuidiObjective: To evaluate the relationship between buccal bone thickness and gingival phenotype of the anterior maxilla after clinical and tomographic evaluation. Methods: 120 teeth were analyzed clinically and in cone beam computed tomography scans. The data obtained from the CT scans corresponded to the thickness of the gingival margin, thickness of the buccal bone board in two regions: 2 and 4 mm apical to the bone crest (EO2 and EO4, respectively) and distance from the cemento-enamel junction to the bone crest. Clinically, the data obtained corresponded to the transparency of the probe in the gingival sulcus and tooth format. The data were grouped and related to the positioning of the tooth in the arch. Results: Tomographically, the measurements showed that the distance from the cemento-enamel junction to the bone crest was higher in canines when compared to the central incisors. The gingival thickness also presented lower values in canines when compared with central incisors. Regarding bone thickness, the values found were similar for all teeth. Only seven teeth had bone thickness> 1,00 mm in EO2. In EO4, only four teeth had bone thickness> 1,00 mm. It was determined with statistical relevance that the bone thickness in EO2 was thicker in relation to EO4 for all groups except for element 21. In the present study it was verified that the non-visibility of the probe is related to bone thickness ≥ 0,96mm, that is, thick bone phenotype. Regarding gingival thickness and probe transparency, our research showed that probe visibility is related to values ≥ 1,04 mm. Thirteen of the tweenty patients presented triangular tooth shape, and only seven presented square shape. Conclusion: It was not possible to accurately and reliably identify the relationship between the transparency of the probe with the buccal bone thickness. However, the visibility of the periodontal probe is associated with measurements of the gingival direction and of the finer vestibular bone plate, but without statistical significance. In the present study, there was statistical significance between the values of thickness of the buccal bone board, in the measurements of 2mm and 4mm apical to the bone crest. Associate largest measurements in the region at 2 mm and the smaller values of thickness at 4 mm apical to the bone crest.Artigo Científico Acesso embargado Análise clínica e tomográfica da relação entre o fenótipo gengival e espessura da tábua óssea vestibular – estudo piloto(2018) Pereira, Julia MachadoObjective: To evaluate the relationship between buccal bone thickness and gingival phenotype of the anterior maxilla after clinical and tomographic evaluation. Methods: 66 teeth were analyzed clinically and in cone beam computed tomography scans. The data obtained from the CT scans corresponded to the thickness of the gingival margin, thickness of the buccal bone board in two regions: 2 and 4 mm apical to the bone crest (EO2 and EO4, respectively) and distance from the cemento-enamel junction to the bone crest.

Materials and methods: Thirty participants (n = 30) divided into three equally distributed groups of both genders (n = 10) participated in the study. Group 1 (dentistry students); group 2 (teachers of dentistry) and group 3 (lay), analyzed 10 intra-oral photographs and answered a questionnaire related to the shape of the tooth and its relation to the patient's gender. In addition, each participant provided their analysis related to the main characteristic that induced their response related to the patient's gender. After the data collection, the evaluation was performed in a descriptive way. For the associations between the degree of difference between the perception of the different groups of evaluators, the chi-square fisher test was used. Results: There was no significant difference (p> 0.05) between the three groups, related to tooth format and patient gender. The percentage of correctness of each of the groups was 61%, 62% and 66% for students, laymen and teachers, respectively. Regarding the percentage of accuracy per photo, it was observed that only photos 5 and 10 had less than 50% accuracy. Conclusion: It was not possible to establish a direct relationship between the shape of the teeth and the sex of the individual. In addition, there was also no difference between the degree of perception among the different groups of evaluators.Artigo Científico Acesso fechado Análise da presença de lesão periapical pré-tratamento endodôntico de pacientes atendidos na Universidade do Sul de Santa Catarina(2019) Vieira, Scarlett FeijóObjective: To associate the frequency of periapical periodontitis previously to endodontic treatment of patients treated by undergraduate students from UNISUL. Materials and Methods: The dental records and radiographs of all patients who received at least one endodontic treatment between August 2015 and December 2018, totaling 410 charts, were analyzed. Data such as gender, age, tooth number, intracanal dressing medication, preoperative pulp condition and presence or absence of periapical lesion were collected. The results were analyzed according to descriptive statistics and for associations, Fisher's Exact Test (statistical significance p≤0.05) was used. Results: A total of 494 teeth were evaluated, of which 261 had a periapical lesion, and 185 (67.8%) were female and 88 (32.2%) were male (p = 0.003). Calcium hydroxide was the most employed intracanal medication (47%). According to the teeth group, the most affected category was the incisors (53.1%), followed by premolars (37.7%) and canines (9.2%) (p = 0.000). Of these, 82.6% were pulped (p = 0.000). In addition, with respect to the age, group of patients between 13 and 29, 30 to 39, 40 to 49, 50 to 59 and 60 to 84 years, presented periapical lesions, respectively, 15%, 29.3%, 26.4%, 17.6%, 11.7% (p = 0.355). Conclusion: The higher frequency of periapical lesion was influenced by gender, position of the tooth in the arcade and preoperative pulp condition.Artigo Científico Acesso fechado Análise da qualidade de vida dos pacientes reabilitados com próteses totais na clínica odontológica da Universidade do Sul de Santa Catarina - Campus Grande Florianópolis(2019) Silveira, Ana Paula WeirichThe present study measured, through the Oral Health Impact Profile questionnaire (OHIP-14), the impact of the prostheses in relation to the quality of life of the patients after oral rehabilitation with total dentures, in the period between 2015-2018. Objective: to evaluate the degree of satisfaction with the total dentures made and to suggest a patient return protocol for prosthetic proservation. Materials and methods: After the analysis of the medical records, a sample of 15 patients who completed the treatment were selected. The questionnaire contained 14 questions, organized so that each two questions integrates one of the seven dimensions: functional limitation, physical pain, psychological discomfort, physical disability, psychological inability, social disability and disability. Patients attended the clinic at previously scheduled times and after answering the questionnaire, underwent a consultation where the oral mucosa and the prosthesis were evaluated, classifying them as to the need for adjustment. Result: in the dimensions where the quality of life is affected, there is a direct connection with the need for adjustment. Values of p≤0.05, according to Pearson's Chi-square test. Conclusion: patients seem satisfied with their prostheses and consider having a good quality of life. However, there is no significant statistical difference that evidences this result, a condition that may be associated with the sample size. Regarding the protocol of patient return, it can be concluded that it can improve the quality of life in the dimensions where it is affected as well as the preservation of the prosthesis after the period of adaptation.Artigo Científico Acesso aberto Análise da relação dos fatores dinâmicos e estáticos que influenciam a estética do sorriso(2018) Carneiro, Isabella Peixoto LunaA beautiful, attractive and healthy smile involve a balance and harmony of factors based on its composition, such as teeth, lips and gums. Often, an imbalance among those elements creates discomfort and dissatisfaction during smile. It is extremely important that the diagnosis and planning of each case are well-designed for treatment success. Thus, the aim of this study was to find a relation among those elements that may influence the aesthetics of the smile. Signifcant findings could help the planning and diagnosis of alterations that compromise the beauty of the smile. To this end, the main structures that make up the smile, such as lips, philtrum and upper incisors, were evaluated using a digital caliper. Sixty participants were divided only in gender, which were grouped according to the measurements. The results presented a relation of high philtrum with lip mobility (p = 0.008) and lip height with a large philtrum during rest (p = 0.008). It was also identified a gender influence on the presence of lip eversion (p = 0.004), the amount of incisal display during rest (p = 0.001), the philtrum height during rest (p = 0.001), the philtrum width during rest (p = 0.019), the red lip height during smile (p = 0.013), the height of the philtrum during smile (p = 0.005) and the philtrum width during smile (p = 0.005).Artigo Científico Acesso fechado Análise da sensibilidade dental em diferentes técnicas do clareamento em dentes vitais: no período de 2017(2018) Dias, Gustavo NauThe search for teeth with greater aesthetic requirement it is a big subject approached in the present times. It is important to mention that, one of the great aesthetic searches related to dentistry is tooth whitening. Objective: Analyze the level of tooth sensitivity and other possible adverse effects due to tooth whitening in the aesthetic clinic of the UNISUL- Grande Florianópolis campus. Materials and Methods: 48 files of tooth whitening control were used, this files were from the dental aesthetic clinic, where the treatments were performed, the files contained some information as > whitening technique performed; type of bleaching gel; concentration of the bleaching gel; degree of sensitivity(evaluated weekly) and others discomforts. The data were tabulated and submitted for descriptive analysis. Results: Basically, there are some types of tooth whitening, citing as more used: home brewed whitening, office whitening, or associated whitening. It is important to emphasize that over the years there was a large increase in the search for tooth whitening, which in most cases generates the result expected by the patient. However, their adverse risks should be warned to all who will submit to this type of procedure. Having as main adverse effects the tooth sensitivity, gingival irritations, actions in restorative materials, surface changes and chemical changes. Conclusão: It was found that in relation to the 4 weeks of sensitivity, one week that had the highest intensity was the first week of treatment. Of the total number of patients diagnosed, 20 were submitted to treatment and related to the mean degree of sensitivity. Regarding sensitivity to the bleaching agent, it was presented that the agent together generated the most sensitivity to treatment and related to the average degree in the first week. Already relating the technique to the larger it generated, it can be said that a homemade technique was the one presented, generating in the first week a greater sensitivityArtigo Científico Acesso embargado Análise de sobrevivência dos implantes curtos e/ou estreitos no tratamento de maxilas atróficas – estudo de 4 anos(2018) Cardoso, Maria EduardaTo evaluate the survival of 14 cases of atrophic maxillae of patients totally edentulous or with indication of exodontia of the remaining elements, treated by protocol type prosthesis, supported only by implants of diameter and / or reduced length, evaluated during a period of 4 years. 6 implants in 14 patients with atrophic maxilla, except one patient who already had one in the mouth and was decided to keep it in function, followed by the protocol type prosthesis. the analyzed variables were: the presence of mobility, pain, radiolucidez peri-implant and bleeding. During the postoperative controls, there was a loss of two implants, in the remaining marginal bone losses, which remained stable after the second year. With in the limitations of this study it is possible to conclude that the use of short and / or narrow implants presented satisfactory results when used in the treatment of the atrophic maxilla with survival rate of 97.59%. it was also possible to observe that the complications were few and of easy resolution without causing great damages to the treatment and to the patient.Artigo Científico Acesso embargado Análise do conhecimento dos alunos de graduação em odontologia acerca da utilização de curativos de demora em endodontia(2022-06-22) Péres, Heloísa BarbatoIntrodução: Durante o tratamento endodôntico a escolha do curativo de demora correto pode ser um desafio para o estudante de graduação.

Aim: To analyze the knowledge among undergraduate dentistry students from the University of the South of Santa Catarina (UNISUL), about the management in cases of dental avulsion. and to verify if there is a positive association between the semester and the knowledge. Materials and methods: This study was accepted in the Ethics Committee in research with human beings of UNISUL, number: 3,076,968. The undergraduate who agreed to participate in the research answered a questionnaire adapted from Reynard et al (2016). The questionnaire was divided into three parts: the first part with questions about demographic data, the second with questions about dental trauma experience and the third with questions about avulsion. The research was applied to 164 undergraduates during the first half of 2019. The data collected were analyzed descriptively and statistically through the chi-square test. Results: The majority of the students who participated in the study were 17 to 21 years old (57.1%), female (78.7%). 70,1% had no previous training for dental trauma and 93,9% never had contact with dental trauma. Among the students who had already been taught about dental avulsion, 81.3% would immediately reimplant the tooth, 93.9% would store in a liquid medium when necessary, where milk was the most found answer (89.8%) Conclusion: The course semester was positively associated with the greater knowledge of undergraduate students about dental avulsionArtigo Científico Acesso embargado Análise do escoamento e da estabilidade dimensional do cimento obturador bio-c sealer após diferentes temperaturas de armazenamento(2021-06-30) Ferreira, LuísaObjetivo: O presente estudo teve como objetivo analisar o escoamento e a estabilidade dimensional do cimento biocerâmico Bio-C Sealer quando exposto a diferentes temperaturas de armazenamento. Materiais e Métodos: Os testes foram feitos de acordo com a norma ISO 6876/2012. Três bisnagas de Bio-C Sealer foram armazenadas, por 30 dias, em diferentes temperaturas cada, sendo G1 à 5ºC em geladeira, G2 à 20ºC em adega e G3 à 35ºC em estufa. Para a realização do teste de escoamento, foi disposta uma quantia de 0,05mL de cada cimento sobre uma placa de vidro e após colocou-se outra placa de vidro e um peso de 100g sobre o conjunto. O peso foi retirado após 10 minutos para a mensuração dos diâmetros com um paquímetro digital (n=3). A estabilidade dimensional foi analisada através de moldes de teflon, que foram preenchidos com os respectivos cimentos (n=6). Após o preenchimento, os conjuntos foram colocados em uma estufa para a sua presa total. Depois, regularizou-se a superfície das amostras, e o comprimento inicial (C) foi mensurado com auxílio de um paquímetro digital. As amostras foram imersas individualmente em recipientes contendo água destilada, onde permaneceram em estufa à 37° C pelo período de 24hs e 7. Em seguida, o comprimento foi novamente medido (CFINAL). A alteração dimensional correspondeu a [(CFINAL – C)/ C] x 100. O teste ANOVA two-way e o teste de Tukey foram utilizados. O nível de significância foi fixado em 5% (α = 0,05). Resultados: Não houve diferença estatisticamente significativa nos valores de escoamento para os diferentes grupos (p > 0,05). Já quanto a estabilidade dimensional, o grupo armazenado em estufa apresentou os maiores valores de expansão quando comparado aos outros grupos (p < 0,05), mas se manteve igual entre si nos diferentes períodos (p > 0,05). Conclusão: As diferentes temperaturas de armazenamento influenciaram na estabilidade dimensional do cimento Bio-C Sealer.Artigo Científico Acesso aberto Análise microscópica da efetividade de diferentes brocas na remoção de material obturador intracanal(2020) Bittencourt, Otília AlbuquerqueThe aim of this study was to evaluate the presence of filling material in the root canals wall after preparation for fiberglass post with the White Post (WP) DC 0.5 drill and the Largo drill in teeth obturated with AH Plus (AHP) sealer. The study had an experimental and qualitative character. Thirty mandibular premolars teeth after endodontic instrumentation were filled with gutta-percha cone and AHP endodontic sealer, and the gutta-percha was thermoplasticized. Two groups (n = 15) were separated: Group 1 - preparations with the WP DC 0.5 drill from FGM; Group 2 -preparations with # 1, # 2 and # 3 Largo drills. After preparation, the specimens were sectioned longitudinally for microscopic analysis of the cervical and middle thirds, and the data were collected in two classifications: first per type of filling material presence, and second to percentage of filling material in the canal walls. No differences were found in the association between the groups in both thirds (p = 1.00) in relation per type of filling material presence, as well as in relation to percentage of remaining material in the cervical third (p = 1.00) and in the middle third (p = 0.505). AHP and gutta-percha were more prevalent in relation per type of material. The percentage of remains most found was less than 50%. In conclusion, even if the material was not completely removed, the use of the WP drill or Largo drill to prepare for fiberglass post does not affect type and percentage of remaining filling material.Artigo Científico Acesso aberto Análise microscópica das paredes dentinárias após diferentes técnicas de preparo para pino de fibra de vidro em dentes previamente obturados com cimento biocerâmico.(2020) Souza, Beatriz FariaObjetivo: O presente estudo teve como objetivo determinar por meio de análise em microscópio óptico, a presença de material obturador remanescente nas paredes do canal radicular, após a técnica de preparo para pino de fibra de vidro (PFV) com diferentes tipos de brocas. Métodos: 30 pré-molares inferiores unirradiculados foram preparados com um sistema de limas reciprocantes WaveOne Gold de #45, no comprimento de trabalho de 14mm. Após o preparo químico-mecânico, os canais radiculares foram obturados através da Técnica Hibrida de Tagger, por meio da compactação termomecânica dos cones de guta-percha Wave One #45 e do cimento endodôntico Bio-C Sealer. Os espécimes foram aleatoriamente divididos em dois grupos, de acordo com a técnica desobturadora: G1 – brocas Largo no 1, no 2, no 3 e, G2 – com a broca White Post DC 0.5. Após preparo do canal radicular para o PFV, foi realizada a análise em microscópio óptico das paredes do canal radicular, afim de determinar o tipo e o percentual de material obturador remanescente. Os dados foram analisados através de testes de associação realizados através do teste Exato de Fisher, com nível de significância de 5%. Resultados: Foi observada a presença de material obturador em todos os terços do canal, em ambas a técnicas desobturadoras, sem diferença significativa entre a broca Largo e a broca White Post DC 0.5. Conclusão: Ambos os preparos, utilizando a broca Largo e a broca de indicação do fabricante, não são eficazes na remoção de material obturador das paredes do canal radicular.Artigo Científico Acesso fechado Análise radiográfica dos principais erros e acidentes cometidos por alunos de graduação durante a obturação do sistema de canais radiculares(2020) Külkamp, Hênella ScreminThe aim of this study was to investigate the main mistakes and accidents made during the root canal obturation, performed by undergraduate students from UNISUL, through pre and operative digital periapical radiographs. Also, the presence of a definitive restoration, after the end of the endodontic treatment, was verified. To do that, the dental records from the second semester of 2017 and the first and second semester of 2018 and 2019 of patients who received at least one endodontic treatment, performed by the undergraduation students, were investigated. The following criteria were observed in the radiographs: overfill, underfill, poor obturation 11 (condensation) and coronary obturation limit cut, and the presence of a definitive restoration with composite resin or intrarradicular pin and crown. It was possible to observe that 44.4% of obturations presented themselves with flaws, 7.1% of root canal were underfilled and 3.4% were overfilled. In regard to the coronal cut, 44% presented themselves with insufficient coronal cut and 4.9% were presented excessive coronal cut. Regarding restorations, 71.3% were sealed with provisional material. Therefore, it can be concluded that the most common mistakes and accidents during obturation were in sequence: insufficient coronal cut, underfilling, excessive coronal cut and overfilling. Still, most of the analyzed teeth did not present definitive restoration.Artigo Científico Acesso fechado Associação da proporção áurea e harmonia de sorriso em alunos da Universidade do Sul de Santa Catarina – Pedra Branca(2019) Marcos, Vinicius FreitasIntroduction: In dentistry, there was an increase in the search for a lighter colored smile and more proportionate faces, in view of the increase in the search for facial harmonization and aesthetic requirement, the golden ratio is used in Dentistry for the production of dentures and restorative procedures, being a parameter used between the mesio-distal of the anterior superior teeth. Objective: To estimate the frequency of the golden ratio of the anterior superior teeth and its relation to the harmony of the smile. Method: This study is characterized by an observational, cross-sectional study. Held at the Dental Clinic Unisul, where were photographed smiles of 70 students of the course of Dentistry for convenience, male and female. The photographs were printed to measure the mesio-distal of the anterior superiors and the values obtained tabulated. These photographs were evaluated by a group of dental surgeons (G1) and another group of laymen (G2) who classified as "Harmonic" or "Non-harmonic". Results: The results showed that 4.3% of the relation between the CI / IL was within the golden ratio and only 1.4% between the IL / C. Among the evaluations of G1 32.3% was considered "Harmonic" and 67.7% for "Non Harmonic", while G2 evaluated in 29.5% and 70.5% respectively. Conclusion: The golden ratio was not determinant for a smile to be considered harmonic. Keywords: Esthetic; Perception; Smiling.
