Geralmente são assintomáticos e encontrados em radiografias de rotina. Dentre os tratamentos cirúrgicos temos a enucleação, marsupialização/descompressão ou associação das duas técnicas. Quando a opção de tratamento for enucleação, podem ser utilizados, para melhor cicatrização da cavidade óssea remanescente, enxertos ósseos associados a uma membrana de colágeno. Relato de caso: caso clínico de enucleação de um cisto periapical na região do dente 21, seguido de preenchimento da cavidade óssea remanescente com biomaterial particulado e estabilização do mesmo com uma membrana de colágeno adaptada sobre a região. Resultados: O acompanhamento clínico-radiográfico sugeriu formação óssea em toda área previamente comprometida. Conclusões: a enucleação do cisto periapical foi um tratamento efetivo, pois permitiu uma cicatrização adequada e rápido retorno do paciente à sua rotina.Artigo Científico Acesso fechado Fluorose dentária - desdobramentos atuais sobre o uso racional de fluoretos durante a primeira infância: revisão narrativa(2017) Laitart, AndressaIntroduction: Dental fluorosis is an alteration in the development of enamel caused by chronic ingestion of fluoride during the process of formation of dental elements. Objective: To elaborate a literature review between 2007 and 2017 on dental fluorosis, focusing on the rational use of fluorides during early childhood. Literature review: The use of fluoride dentifrice is usually associated with the occurrence of dental fluorosis, especially when there is use of this product beyond the established limit. Most of the cases of dental fluorosis reported in the current literature, including in Brazil, indicate a very mild or mild degree, and are therefore not considered a public health problem. Conclusion: It is important that preventive measures be followed by parents or guardians in the form of supervising toothbrushing with fluoridated dentifrices from infancy, in order to obtain the beneficial effects of fluoride.Monografia Acesso fechado Influência de diferentes técnicas obturadoras no preenchimento dos canais secundários(2017) Matos, Luiza de OliveiraThe premolars present morphological complexity of the canals. Studies indicate the prevalence of secondary canals to be found in the middle and apical thirds. The objective of the present study is to evaluate the influence of different shaping and filling techniques in the filling of secondary canals through two differents filling and shaping techniques. Forty artificial, radiopaque and unirradicular premolars had their crowns sectioned and had a standardized length of 19 mm length. Two secondary canals were made in the apical and middle thirds, in the mesial and distal walls of all specimens with a 0.4 mm diameter drill, and then the teeth were divided into groups according to the shaping and filling technique: MM/TCL- shaping with manual technique and filling with the lateral condensation technique, PT/TCL- shaping with the mechanized technique (pro taper system) and filling with the lateral condensation technique, MM/THT- shaping with manual technique and filling with tagger hybrid technique and PT/THT- shaping with mechanized technique (pro taper system) and filling with tagger hybrid technique. All specimens were x-rayed, and then the images were analyzed by a radiologist who did the evaluation blind. The evaluation crieteria were: “completely filled” for when there was radiopaque material throughout the extent of the secondary artificial canals, “partially filled” for when presented radiopaque material in part of the canals extension and “empty” for when it didn’t presente radiopaque material in your extension. After the evaluation, the chi-square test and the Pearson's test were applied to verify possible differences and where they were to fill the secondary canals. It was considered statistically significant for 0.05. The results showed a significant difference in the apical third, in which the PT/TCL group had the highest percentage of fully filled secondary canals while the MM/TCL group had the highest amount of empty canals. In the treatment of teeth where the prevalence of secondary canals in the apical third is larger, the lateral condensation technique presented a better performance when associated with the mechanized modeling technique.Monografia Acesso embargado Influência da reabilitação oral na satisfação e na qualidade de vida do desdentado total: revisão de literatura(2017) Hawerroth, DéboraTotal edentulism creates a condition of aggravation to oral health, it decreases masticatory capacity and makes the consumption of several foods with important nutrients difficult. In addition, it influences phonation, negatively affects the appearance of the individual, and it may arouse a probable psychological shock, which generates a direct interference in the person’s quality of life. The current therapeutic proposals for total edentulous are conventional total dentures, implant-retained overdentures and implant-supported fixed prostheses. Patients rehabilitated with total removable prostheses are very commonly dissatisfied regarding the prosthesis retention and stability, especially the lower prosthesis. The implants, when used as fixation for these type of prostheses, add advantages in these aspects. However, there are some limitations that do not allow its indication in all cases, such as general health conditions, quantity and quality of bone, and the high cost for most individuals who need dental prostheses. Thus, through a narrative review of the literature, this work aims at evaluating total edentulous individuals, describing and interpreting satisfaction, quality of life, as well as psychosocial, nutritional, aesthetic and physiological aspects, seeking the best proposal for the rehabilitation of these patients.Monografia Acesso aberto Prótese total sobre implantes: revisão de literatura(2017) Broering, Fernanda MachadoDentistry has stood out in the world scene when practicing rehabilitation procedures and techniques, aiming at the health and esthetics of individuals. Within this context, oral rehabilitation using the full denture procedure on implants with immediate loading showed a significant advance in recent years. The osseointegration was proposed by Bränemark through two surgical stages, but the evolution of the surgical techniques provided the improvement of the diagnostic methods, the improvement in the quality of the implant, as well as the knowledge of the tissue biology adjacent to the implant. In this way, the development of new technologies has been supporting studies for a single surgical stage and the placement of the prosthesis on newly installed implants. The objective of this research is to review the literature studies that support the use of the total prosthesis over newly installed implants. It is concluded that the total prosthesis procedure on the implants brings advantages to the patients, since there is the reduction of the working time, less postoperative discomfort and, above all, it returns the masticatory and aesthetic function immediately after the surgery.Estudo de Caso Acesso fechado Mordida aberta anterior - estudo de caso(2017) Back, Letícia MeyerDental malocclusion is altered growth and development, with the anterior open bite defined as the negative vertical overlap between the incisal edges of the anterosuperior and inferior teeth. Considered a complex anomaly, difficult to treat and with a high degree of impairment of the facial and aesthetic balance, it generates significant dental and skeletal alterations. The aim of this study is to study a case and review the literature on the etiology and treatment modalities of anterior open bite. In the present study, an infant-juvenile patient with mixed dentition and presence of anterior open bite was selected. In this patient, the interceptive device, McNamara with lingual grid, was installed. After 4 months of use of the orthodontic device, correction of the anterior open bite, improvement in facial harmony and lingual interposition was observed. It is concluded with this work that the treatment of this malocclusion should be performed early and preferably in a multidisciplinary manner. It is of great importance that dentistry professionals know the main etiologies for the development of this malocclusion, since early intervention results in better results and greater stability of the treatment, besides directly interfering in the quality of life of the patient by restoring the correct functioning of the stomatognathic system.Monografia Acesso fechado Efetividade de selantes aplicados por estudantes de odontologia na prevenção de lesões cariosas em dentes permanentes(2017) Marques, Viviane SilveiraObjective: This study aims to evaluate the pit and fissures sealants effectiveness when applying for Undergraduate Dental students at the University of Southern Santa Catarina (Unisul), after at least 6 months, as well as to estimate caries prevalence into participants. Methods: This is an observational and cross sectional study, with a non-probabilistic and intentional sample and includes individuals who received sealants in permanent teeth at the clinics of the degree course in Dentistry. The participants were identified by the medical records at Unisul. The effectiveness of pit and fissures sealants was assessed by analysis of retention standards, and will follow validated script. The prevalence of caries in sealed teeth was assessed by ICDAS II index. The sociodemographic variables age, sex and monthly household income the considered. A researcher training was conducted by supervisor of research in clinics at the University of Southern Santa Catarina. The descriptive analysis and the Chi square test was tested and p value ≤0,05. The project was approved by ethical counsel at the Unisul University by number 1,824,523. Results: The response rate was 94.7% (n = 18). The sample was 2/3 of female (72.2% CI95% 49.1, 87.5), 60% received 3 or less Brazilian monthly household income, highest proportion of participants had sealed their teeth at least 9 months. Less than 2/3 of the sample received Fluroshield as restorative material, with relative isolation being the most prevalent (72.2% CI 95% 49.1; 87.5). The prevalence of some loss of retention was 50% (95% CI 29.0, 71.0). Among the 57 teeth evaluated, 70.2% had total retention. The teeth most affected by loss of retention were maxillary left second molars (40%). More than 2/3 of the sample did not presented dental caries (88.9% CI 95%, 96.9%). No significant associations were found. Conclusion: Although the patients had no caries recurrence, half of the sample presented some loss of retention of the sealants, even though to a greater number of total retentions between the teeth were present. This reflects the importance and attention to the planning and correct application of sealing techniques by dentistry students.Artigo Científico Acesso fechado Perfil dos pacientes com necessidades especiais atendidos no Centro de Especialidades Odontológicas (CEO) do município de Palhoça - SC(2017) Southier, Rafaela CarlottoIntroduction: Patients with special needs (PSN) require specialized care, which can be onlay for a period or throughout their life.

The technique of revascularization can give rise to a periapical barrier, through the induction of bleeding, the periapical origin in order to create a clot within the canal, which is protected by a material to allow a neoformation of dental structures. Repair cements are developed for use in the presence of blood, and their properties may be altered in the presence of blood. The present work is evaluated by the marginal adaptation and porosity by computerized microtomography. Materials and Methods: Twenty four roots of bovine incisors 10 mm high were filled with Mineral Trioxide Aggregate (MTA). The examples were randomly divided into two groups, according to the storage medium (G1 and G2). All the specimens were attached the analysis through microtomography computerised, evaluation of the parameters marginal adaptation, number of pores and percentage of porosity. The results were evaluated by statistical tests. Results: The G2 group presented a lower percentage of closed porosity. Conclusion: It is possible that the exposure to blood has a negative effect on MTA, due to the increase in the percentage of pores on material.Monografia Acesso fechado Autopercepção e condições de saúde bucal de adultos atendidos na clínica da Universidade do Sul de Santa Catarina(2018) Costa, Juliana Fortes Lages MartinsOral health self-perception can be a predictor of normative status and contribute to planning oral health services and quality of life. Objective: To evaluate the agreement between negative self-perception and oral treatment needs of adults attended at the University of Southern Santa Catarina (UNISUL) and associated factors. Method: Descriptive and cross-sectional study with adults aged 20 to 59 years, attended at the school of Dentistry at the UNISUL, Palhoça, SC. Data included: oral health self-perception, general health conditions (smoking, physical activity and alcohol consumption), gingival bleeding, prosthesis use, unilateral chewing and use of dental services. Clinical conditions assessed by students: prevalence of caries, prevalence of calculus and O'Leary index. Besides sex, age, schooling and household monthly income. Descriptive analysis and association by Pearson's Chi-Square test was conducted. Results: The prevalence of negative self-perception was 31.9%. With age, the significant increase to negative self-perception was observed, the inverse for higher schooling (12.9%). Using public service (52.1%) and unilateral chewing (20%) were associated with negative self-perception. A concordance of 95% and 100% between caries and calculus and negatively reporting oral health was observed respectively. For the dental biofilm the agreement was 67%. Conclusions: Significant agreement with negative self-perception was observed and suggesting that adults perceive their poor oral health and needs, although lower value for biofilm, in this case, initial conditions in the development of oral diseases.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 embargado Comparação da eficácia de dois sistemas rotatórios na desobturação endodôntica(2018) Santos, Nicole Buss dosIntroduction: After filling, the tooth may present therapeutic failure, requiring endodontic retreatment. The new intervention consists in the removal of all the filling material of the root canal, achievement of a new instrumentation, cleaning and three-dimensional obturation trying to restore periapical health. Materials and methods: Thirty unirradicular human teeth were instrumented and obturated in a similar way and divided into two groups. G1, the filling material was removed using instruments of the Protaper® Universal Retreatment system. G2, the removing of obturated material was made with the Easy © ProDesign Logic RT system. After the endodontic retreatment, the teeth were cleaved longitudinally. The specimens were analyzed by thirds(cervical, medium and apical) in the stereomicroscope with a 16x magnification and following the scores:0 (when the third showed a trace of filling material in less than 20% of the area),and 1(when the third analyzed showed a vestige of filling material in more than 21% of the area). The results were analyzed for the quantitative variable, by the t-student test, and for the qualitative variables, by Fisher's exact test, considering, p <0.05. Results: In the t-student test, G2 presented average time of endodontic retreatment lower than G1, Fisher's exact test showed no statistical difference between the amount of traces of remaining obturated material in the cervical, medium and apical thirds comparing the two groups studied.(p>0,05). Conclusion: In general, the two groups were generally effective in removing the filling material, but G2 presented statistically lower average working time. Key words: Endodontics; Endodontic retreatment; Protaper® Universal Retreat; Easy© ProDesign Logic RT.Estudo de Caso Acesso aberto Implante imediato com provisionalização imediata através de cicatrizador multifuncional de PEEK - relato de caso clínico(2018) Santos, Fernanda VenâncioThe aim of this article was to present a clinical case where the provisional restoration was fabricated over a multifunctional PEEK healing abutment, a biocompatible polymer can be customized and has excellent bond strength to resin composites. A dental implant was loaded at the region of tooth 21. After a palatal approach for implant placement, the buccal gap was filled with an alloplastic graft (Nanosynt). Then, the immediate restoration was fabricated with the multifunctional PEEK and an acrylic tooth form. At the delivery of the definitive restoration, the peri-implant soft tissue health and architecture were preserved.Artigo 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 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. 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 five teeth (7,57%) had bone thickness> 1,00 mm in EO2. In EO4, only 3 (4,54%) 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 some groups (13, 12, 11 and 22). 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. Nine of eleven patients presented triangular tooth shape, and only two presented square shape. ABSTRACT Objective: 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. 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 five teeth (7,57%) had bone thickness> 1,00 mm in EO2. In EO4, only 3 (4,54%) 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 some groups (13, 12, 11 and 22). 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. Nine of eleven patients presented triangular tooth shape, and only two 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 fechado Efeito antimicrobiano do óleo essencial de Melaleuca alternifolia contra o biofilme de Enterococcus faecalis estabelecido no canal radicular de dentes bovinos(2018) Griggio, JosiasAim: The aim of this study was to evaluate, ex vivo, immediate and residual antimicrobial effect of Calen plus camphorated p-chlorophenol paste (PMCC-Calen™), 5% Melaleuca alternifolia essential oil (5% MA), and calcium hydroxide [Ca(OH)2] associated with 5% MA against intracanal E. faecalis biofilm. Material and Methods: Fifty six bovine dentin tubes were inoculated with E. faecalis to allow biofilm formation. After one week specimens were randomly divided according to the intracanal dressing (n = 14): G1 - Calen PMCC; G2 - 5% MA; G3 - Ca(OH)2 + 5% MA; G4 - control - saline 0.85%. After 7 days, intracanal medications were removed and the remaining biofilm cells were collected. Residual antimicrobial effect promoted by medications was analyzed by immersing specimens in sterile culture medium for 7 days. Then, another microbiological sampling was performed. The bacterial viability test, by colony forming units (CFUs) counting, was carried out from the material collected in both moments (n = 10). Root canal surface and biofilm, if present, from two samples per group, for each period, were observed by scanning electron microscopy. The mean values of CFUs were analyzed by Kruskal-Wallis and post hoc Dunn tests (P < 0.05). Results: When immediate antimicrobial effect was analyzed, G1, G2 and G3 reduced 99.37%, 97.40% e 100% of CFUs, respectively, compared to control (p < 0.05). G1 and G3 showed residual antimicrobial effect, reducing 84.48% and 100%, respectively, of viable E. faecalis biofilm cells compared to control. Conclusion: Although Calen PMCC and 5% MA have demonstrated expressive antimicrobial effect, the association CaOH2 + 5% MA eradicated intracanal E. faecalis biofilm at immediate and residual analysis. Keywords: Biofilm. Disinfection. Enterococcus faecalis. Volatile oils.Artigo Científico Acesso fechado Análise da eficiência do aplicativo “Endo App” com alunos do curso de graduação do curso de odontologia da Universidade do Sul de Santa Catarina(2019) Nogueira, DanielleIntroduction: The "Endo app" application was created with the purpose of reducing the difficulties of undergraduates, providing greater understanding and confidence when making clinical protocols.
