Orthodontic treatment in traumatized permanent teeth: a systematic review / Tratamento ortodôntico em dentes permanentes traumatizados: uma revisão sistemática

Objective: to analyze, through literature review, the available literature on orthodontic treatment in traumatized permanent teeth. Methods: A literature search was performed in electronic databases (PubMed and SciELO) using the descriptors [tooth injuries] OR [injuries, teeth] OR [injury, teeth] OR [teeth injury] OR [injuries, tooth] OR [injury, tooth] OR [tooth injury] OR [teeth injuries] AND [orthodontics]. Observational studies and clinical trials were included, narrative reviews, laboratory and in vitro studies, case reports and series as well as articles that presented abstracts written in languages other than Portuguese, English and Spanish were excluded from the study. Two reviewers considered the eligibility, the risk of bias of the analyzed data and the qualitative synthesis of the studies included. A total of 1,322 references were found and 4 articles met all inclusion criteria and were included in the qualitative analysis. Some consequences like pulp necrosis and root resorption have been highlighted and trauma severity should be considered when orthodontically intervening in previously traumatized teeth. Final considerations: The traumatized teeth can be orthodontically treated as long as the time of tissue reorganization is respected, and the pull and periodontal conditions are followed up.(AU)

Non-surgical periodontal treatment for drug-influenced gingival enlargement: a four-year follow-up case report

ABSTRACT: Drug-influenced gingival enlargement is considered to be an important side effect related to the use of some medications and often produces important esthetic changes for patients, as well as clinical symptoms such as pain, bleeding, abnormal tooth movement and occlusion problems. Anticonvulsants, immunosuppressants and antihypertensive drugs have been reported as the main inducers of these periodontal disorders. This case report describes the 4-year clinical follow-up of a young patient with a history of excessive gingival enlargement as a consequence of drug therapy for epilepsy (phenytoin and phenobarbital); the nonsurgical periodontal treatment of the excessive gingival enlargement was associated with the replacement of the patient's epilepsy medications with valproic acid. We conclude that intensive mechanical control of bacterial biofilms, instruction on oral hygiene guidelines and behaviors and the substitution of alternative anticonvulsant medications are the best way to control the drug-influenced gingival enlargement.

Retentive efficacy, antimicrobial and cytotoxicity comparisons between different types of commercial and experimental denture adhesives with antifungal action.

The effect of the addition of nystatin and an alternative antifungal derived from pyrazoles in different commercial denture adhesives on their retentive efficacy, cytotoxicity and antimicrobial activity against Candida albicans was evaluated. Commercial denture adhesives were prepared with the inclusion of nystatin and 3,5-diaryl-4,5-dihydro-1H-pyrazole-1-carboximidamide (pyrazole) in three concentrations: 23.78 %w/w, 3.02 %w/w, and 0.31 %w/w (0.015 g, 0.0015 g, and 0.00015 g, respectively). The retentive efficacy was tested observing the influence of the medium, type of commercial denture type and the test condition (dipping). The antifungal action through disk diffusion and direct contact tests at 1, 4, 8 and 12 h and cytotoxic activity was evaluated in mouse fibroblasts (NIH/3T3) by the MTT reduction colorimetric assay. The addition of pyrazole and nystatin in commercial denture adhesives did not affect retentive efficacy rates and enhanced antifungal actions against Candida albicans. Results show a possibility of using denture adhesives as a delivery system for commercial antifungals (Nystatin) or pyrazole, with the second concentration (1,560 µg-3.02 %w/w) as the most efficient.

Interdisciplinary esthetic approach in clinical dental rehabilitation.

During the esthetic evaluation of smile, the presence of diastemas, tooth color, size and shape, and the amount of gingival exposure are important factors to be considered. A 23-year-old female patient was referred to us with a dissatisfaction with her smile. After clinical examination revealed esthetic alterations as generalized tooth yellowish discoloration, a slight diastema in the upper anterior region, and a shortened appearance of maxillary dental crowns, providing a gingival smile. The proposed treatment consisted of an esthetic rehabilitation for resolution of gummy smile and closure of diastema in anterior teeth by the use of digital planning as a guide for the accomplishment of integrated procedures. The result obtained by the multidisciplinary treatment associating periodontal surgical procedure for esthetic crown lengthening with in-office bleaching and direct restorations with composite resin, by digital planning, provided evident harmonization between tooth color and shape and gingival contour, enabling more harmonious smile esthetics.

Fatores preditivos do sucesso en dodôntico em tratamentos realizados por alunos de graduação§ / Predictive factors of endodontic success in treatments performed by undergraduate / Factores predictivos del éxito endodontico en tratamientos realizados por un estudiante

Resumo Introdução e objetivo: Ainda são escassos os estudos que avaliam com exatidão o sucesso do tratamento e retratamento endodônticos e quais as falhas que realmente impactam no desfecho dos mesmos. Determinar o índice e os fatores preditivos para o sucesso de tratamentos e retratamentos endodônticos, realizados por alunos de graduação com o mesmo nível de aprendizado. Materiais e métodos: Foram verificados os registros de proservação, com pelo menos 12 meses, dos tratamentos endodônticos realizados na Faculdade de Odontologia de Pelotas, analisando o sucesso ou o fracasso endodôntico, de acordo com critérios clínicos e radiográficos. As variáveis preditivas no resultado do sucesso do tratamento foram: dente, número de canais, coroa dentária, sintomas, diagnóstico da polpa e índice periapical radiográfico. As variáveis relacionadas ao tratamento foram: técnica de instrumentação, número de sessões e limite de instrumentação apical. Resultados: 136 tratamentos endodônticos foram realizados com um acompanhamento de, pelo menos, 12 meses. A avaliação mostrou que o sucesso endodôntico foi influenciado pelo número de sessões (P = 0,015), diagnóstico inicial e grupo dentário (P= 0.014). Também foi possível observar que, quanto maior o índice periapical radiográfico inicial, pior o prognóstico endodôntico (P < 0.001). Conclusão: O índice de sucesso do tratamento endodôntico foi de 96.7% para casos de polpa vital, 87.5% para os casos de necrose pulpar e 92.9% em retratamentos. Estes índices foram influenciados pelo dente tratado, diagnóstico inicial, índice periapical radiográfico inicial e pelo número de sessões utilizadas no tratamento.

Abstract Introduction and objective: There are still few studies that accurately address endodontic success and which failures actually impact the endodontic treatment outcome. Determine success rate and predictive factors for successful endodontic treatment and retreatment by undergraduate students of the same learning level. Materials and methods: The preservation records (12 months) of the endodontic treatments performed in the Faculty of Dentistry of Pelotas were verified, indicating the success or failure of the treatment. Predictive variables in the outcome of successful endodontic treatment or retreatment were: tooth, number of channels, dental crown, symptoms, pulp diagnosis, radiographic periapical index. The treatmentrelated variables were: instrumentation technique, number of sessions and apical instrumentation limit. Results: 136 endodontic treatments were performed with a follow-up of at least 12 months. The evaluation showed that endodontic success was influenced by the number of sessions (P = 0.015), initial diagnosis and dental group (P = 0.014). It was also observed that the higher the initial radiographic periapical index, the worse the endodontic prognosis (P < 0.001). Conclusion: The success rate of endodontic treatment was 96.7% for cases of vital pulp, 87.5% for cases of pulp necrosis and 92.9% for retreatments. These indices were influenced by type tooth, initial diagnosis, initial radiographic periapical index and the number of visits used in the treatment.

Resumen Introducción y objetivo: Todavía hay pocos estudios que aborden con precisión el éxito endodóntico y cuáles fracasos realmente impactan el resultado del tratamiento endodóntico. Determinar la tasa de éxito y los factores predictivos para el tratamiento y el retratamiento exitoso de endodoncia por estudiantes universitarios del mismo nivel de aprendizaje. Materiales y métodos: Se verificaron los registros de conservación (12 meses) de los tratamientos de endodoncia realizados en la Facultad de Odontología de Pelotas, lo que indica el éxito o el fracaso del tratamiento. Las variables predictivas en el resultado de un tratamiento o retratamiento endodóntico exitoso fueron: diente, número de canales, corona dental, síntomas, diagnóstico pulpar, índice periapical radiográfico. Las variables relacionadas con el tratamiento fueron: técnica de instrumentación, número de sesiones y límite de instrumentación apical. Resultados: se realizaron 136 tratamientos de endodoncia con un seguimiento de al menos 12 meses. La evaluación mostró que el éxito endodóntico estaba influenciado por el número de sesiones (P = 0.015), el diagnóstico inicial y el grupo dental (P = 0.014). También se observó que cuanto mayor es el índice periapical radiográfico inicial, peor es el pronóstico endodóntico (P <0.001). Conclusión: La tasa de éxito del tratamiento endodóntico fue del 96.7% para casos de pulpa vital, 87.5% para casos de necrosis pulpar y 92.9% para retratamientos. Estos índices fueron influenciados por el tipo de diente, el diagnóstico inicial, el índice periapical radiográfico inicial y el número de visitas utilizadas en el tratamiento.

Esthetic treatment of buccal exostoses: a case report.

Buccal exostoses are benign bony protuberances that may grow over time but rarely result in functional alterations. The diagnosis is established by a combination of medical history and clinical and radiographic features of the affected region. This case report describes the surgical treatment of bilateral bone projections on the buccal surface of the maxilla that represented an undesirable esthetic alteration to the patient. The surgical procedures, which were performed at separate appointments for the left and right sides, involved reflection of full-thickness flaps and careful osteotomy with a carbide spherical drill and a Rhodes chisel. At completion of the procedures, flat buccal bone ridges with a clear esthetic improvement were observed. At the follow-up examination (3 months postsurgery on the left side and 1 month on the right), the presence of stable periodontal tissue-positioned where it was located during the immediately postoperative period-indicated a satisfactory clinical result.

Hiperplasia gengival associada ao uso de anticonvulsivantes à base de ácido valpróico / Gingival hyperplasia associated with the use of valproic acid-based anticonvulsants

Anticonvulsivantes são drogas capazes de modificar a resposta dos tecidos gengivais a processos inflamatórios na presença ou não de placa bacteriana, induzindo o crescimento gengival. O presente trabalho revisou a respeito das alterações periodontais exacerbadas pela utilização de anticonvulsivantes à base de ácido valpróico. Foram incluídos no estudo todos os trabalhos que pudessem descrever algo a respeito das características bioquímicas e farmacológicas do ácido valpróico e sua correlação com as alterações periodontais hiperplásicas. A pesquisa bibliográfica foi realizada nas bases Scopus, PubMed, BVS, Web of Science e Scielo utilizando os descritores "sodium valproate" "valproic acid" "gingival enlargement" e "gingival hyperplasia". Como resultado, um total de 111 referências foram encontradas e 54 artigos contemplavam todos os critérios de inclusão e foram submetidos a análise qualitativa. Algumas hipóteses sugerem um papel determinante dos fibroblastos, citocinas inflamatórias e também com a síntese de metaloproteinases na resposta tecidual. Concluiu-se que o mecanismo interveniente na histopatogênese do tecido conjuntivo desencadeadas pelo ácido valpróico e com repercussões nos tecidos periodontais ainda é pouco compreendido e apresentam pouca relação com o acúmulo de biofilme dentário, sendo decorrentes mais por mecanismos atribuídos ao próprio medicamento (AU)

Anticonvulsants are drugs capable of modifying the response of gingival tissues to inflammatory processes in the presence or absence of plaque, inducing gingival growth. The present study reviewed the periodontal changes exacerbated by the use of valproic acid-based anticonvulsants. All studies that could describe something about the biochemical and pharmacological characteristics of valproic acid and its correlation with hyperplasic periodontal changes were included in the study. The literature search was carried out in the bases of Scopus, PubMed, BVS, Web of Science and Scielo using the descriptors "sodium valproate" "valproic acid" "gingival enlargement" and "gingival hyperplasia". As a result, a total of 111 references were found and 54 articles covered all the inclusion criteria and were included in the qualitative analysis. Some hypotheses suggest a role of fibroblasts, inflammatory cytokines and also the synthesis of metalloproteinases in the tissue response. It was concluded that the mechanism involved in the histopathogenesis of connective tissue triggered by valproic acid and with repercussions on the periodontal tissues is still poorly understood and presents little relation with the accumulation of dental biofilm, being more due to mechanisms attributed to the drug itself (AU)

Dor pós-operatória em dentes tratados endodonticamente por estudantes de Odontologia, utilizando técnicas manual e reciprocante / Postoperative pain in teeth endodontically treated by dental students, using manual and reciprocating techniques

O objetivo do presente estudo foi determinar a frequênciae/ou intensidadede dor pós-operatória e os fatores associados a esta ocorrência em tratamentos e retratamentos endodônticos realizados pelas técnicas de instrumentação manual e reciprocante, por estudantesde graduação em Odontologia da Universidade Federal de Pelotas. Para tal, utilizou-se informações dos prontuários de pacientes atendidos por estudantesdo último ano de graduação, no período compreendido entrejaneiro de 2017 ejulho de 2019, totalizando 182 tratamentos. A dor foi registrada por meiodaEscala de Avaliação Numérica da Dor (EAND). Considerou-se como variáveis preditivas no desfecho de dor pós-operatória: dente, número de canais, sintomas, coroa dentária, tratamento indicadoe índice periapical radiográfico. Como variáveis relativas aos tratamentos, técnica de instrumentação, número de sessões e limite apical de instrumentação. Havia relato de dor no momento do tratamento em 28% dos prontuários, enquanto 11,5% não reportaram dor prévia. Em 149 casos (81,9%) incluídos neste estudo não foi relatada a ocorrência de dor pós-operatória, enquanto dor leve foi relatada em 17 casos (9,3%), moderada em 6(3,3%)e intensa em 10(5,5%). Em 67,4% dos casos dos dentes foram tratados até a marcação 0 do localizador apical,enquanto em 32,6% o comprimento foi estabelecido a 1mm desta marcação. Não houve associação entre o tipo de tratamento realizado e a ocorrência de dor pós-operatória (p=0,206). Conclui-se que, entreos fatores avaliados, apenas a sintomatologia prévia apresentou associação com a maior frequência de dor pós operatória (AU).

This study determined the frequency and/or intensity of postoperative pain and factors associated with such occurrence in endodontic treatments and retreatments performed by manual and reciprocating techniques, by undergraduate dental students at the Federal University of Pelotas. For that purpose, data were collected from the records of patients treated by last-term undergraduate students, in the period between January 2017 and July 2019, adding up to 182 treatments. Pain was recorded by the Numerical Pain Rating Scale (NPRS). The following predictive variables were considered in the outcome of postoperative pain: tooth, number of canals, symptoms, dental crown, indicated treatment and radiographic periapical index. The variables related to the treatments included the instrumentation techniques, number of sessions and apical limit of instrumentation. There was report of pain during treatment in 28% of records, while 11.5% did not report previous pain. In 149 cases (81.9%) included in this study there were no reports of postoperative pain, while mild pain was reported in 17 cases (9.3%), moderate in 6(3.3%)and intensive in 10(5.5%). In 67.4% of cases, the teeth were treated up to mark "0"of the apex locator, while in 32.6% the length was established at 1mm from this mark.There was no association between the type of treatment performed and the occurrence of postoperative pain (p=0.206). It was concluded that, among the evaluated factors, only the previous symptomatology was associated with higher frequency of postoperative pain (AU).

Clinical treatment of necrotizing ulcerative gingivitis: a case report with 10-year follow-up.

The aim of this case report is to describe the diagnosis and treatment of a patient with necrotizing ulcerative gingivitis. An 18-year-old man with no systemic problems reported with chief complaints of gingival bleeding during toothbrushing and spontaneous pain. Clinical examination revealed significant plaque accumulation on the surfaces of all teeth as well as papillary necrosis involving mainly the anterior teeth. Treatment included an initial phase of supragingival plaque and calculus removal along with at-home use of 0.12% chlorhexidine gluconate mouthrinse twice a day for 30 days. After the initial phase, subgingival scaling was performed, and regular oral hygiene methods were resumed by the patient. After active therapy was completed, a periodontal maintenance regimen was established, and the patient was recalled for periodontal maintenance therapy. Follow-up occurred weekly throughout treatment, monthly for the first 6 months posttreatment, and 2-3 times a year during the periodontal maintenance therapy. Clinical results after 10 years showed that this approach controlled the acute phase and maintained the patient's periodontal health over time.

Systemic and clinical treatment of gingival hyperplasia associated with use of anticonvulsant

ABSTRACT: Anticonvulsants are drugs that can modify the gingival tissues response to inflammatory processes in the presence of dental plaque, inducing gingival overgrowth. Preexisting gingival inflammation induced by dental plaque seems to be a favorable condition to the development and/or expression of gingival overgrowth. This study describes a case in which the use of phenytoin and phenobarbital anticonvulsant associated with the presence of dental plaque provided a large and severe extent of gingival alteration. We concluded that it was possible to achieve a good result in the patient with an intensive mechanical control of dental plaque, oral hygiene orientations and substitution of the drug for other alternative medication.

Effect of hydrogen peroxide on color and whiteness of resin-based composites.

OBJECTIVE: To evaluate the influence of a 35% hydrogen peroxide gel on color and whiteness changes of resin-based composites (RBC). MATERIALS AND METHODS: Discs (n = 10; shade A3.5 enamel; and 8 mm diameter and 2 mm thick) were fabricated from three RBC (DF- Durafill, Heraeus Kulzer; ED- IPS Empress Direct, Ivoclar Vivadent; and AP- Amelogen Plus, Ultradent Products). Three subgroups were obtained for each RBC: before bleaching (T0 ) and after first (T1 ) and second (T2 ) bleaching applications. A dental spectrophotometer (VITA Easyshade, Vita Zahnfabrik) was used to obtain CIELAB color coordinates and whiteness index for dentistry (WID ) in all periods. CIELAB ( ΔEab* ) and CIEDE2000 (ΔE00 ) color differences were also obtained. Perceptibility (PT) and acceptability (AT) thresholds were used to analyze values of ΔEab* , ΔE00 , and ΔWID . Two-way analysis of variance (ANOVA; for L*, a*, b*, and WID ) and one-way ANOVA and Tukey tests (for ΔEab* and ΔE00 ) were used to analyzed the results (α = 0.05). RESULTS: L* and WID values from all RBC did not change after bleaching applications (T1 and T2 ) (P > .05). There were no significant differences in color differences ( ΔEab* and ΔE00 ) among all RBC evaluated after bleaching applications (T1 -T0 and T2 -T0 ; P > .05). Regardless of the RBC, mean values of ΔE00 between all different periods were always below 50%:50% PT value. CONCLUSIONS: The 35% hydrogen peroxide bleaching gel influences on color and whiteness of resin-based composites. However, color changes were not clinically perceived and whiteness variations were clinically acceptable. CLINICAL SIGNIFICANCE: Patients should be advised that existing composite restorations might not match the natural tooth color after bleaching, and their replacement may be required.

O traumatismo maxilofacial de mulheres causado porviolência tem sido mais abordado nos últimos anos. Oaumento dos casos tem sido acompanhado do aumentodas denúncias de violência contra a mulher, tornando oproblema mais visível à sociedade. Objetivo: o presentetrabalho teve o objetivo de fazer uma revisão de literaturaque aborda a prevalência de traumas maxilofaciaisdecorrentes de violência física contra mulheres e os fatoresrelacionados às lesões. Revisão de literatura: os estudosreportaram prevalências entre 24,4% e 81,0% detraumatismos maxilofaciais em mulheres causados porviolência. A maioria aponta o marido ou o companheirocomo principal agressor e o uso de força física comoprincipal tipo de agressão. Mulheres com idades entre 20e 39 anos, dependentes econômicas ou de baixa renda ecom nível de escolaridade inferior são mais susceptíveisa apresentar traumatismo maxilofacial mais prevalentenos tecidos moles. As consequências mais relatadasentre as mulheres com traumatismos maxilofaciais porviolência incluem problemas de autopercepção, de inter-relação social e de baixa autoestima. Consideraçõesfinais: conclui-se que a prevalência de traumatismosmaxilofaciais por violência em mulheres é alta, estandorelacionada à idade, à dependência econômica, ao graude escolaridade, à ocupação e a problemas psicoafetivosque podem também influenciar a dinâmica familiar. (AU)

Maxillofacial trauma caused by violence to women has been addressed more in recent years. The increase of trauma has been accompanied by an increase in the reported cases of violence to women, making the problem more visible to society. Objective: by means of a literature review, the present study aimed to review the prevalence of maxillofacial trauma caused by physical violence to women and the factors related to such injuries. Literature review: the studies reported that the prevalence of maxillofacial trauma in women due to violence was between 24.4% and 81.0%. Most studies indicate the husband or partner as the primary aggressor, and the use of physical force as the main type of aggression. Women aged between 20 and 39 years, who are economic dependent or have low income and low level of education are more likely to present maxillofacial trauma more prevalent in soft tissues. The consequences most reported among women with maxillofacial trauma caused by violence included issues regarding self-perception, social interrelation, and low self-esteem. Final considerations: it is concluded that the prevalence maxillofacial trauma caused by violence to women is high and it is related to age, economic dependence, level of education, occupation, and psycho-affective problems, which may also influence family dynamics.

Natural Crown Bonding of Anterior Fractured Teeth at Different Levels of Complexity: A 14-Month Follow-up.

Dental fractures comprise the most frequent form of traumatic dental injury and often require an immediate procedure for their treatment. The repositioning of fractured crown fragments using the bonding fragment technique offers several advantages, including the reestablishment of function, esthetics, shape, shine, and surface texture, in addition to the maintenance of the original contour and alignment of the teeth. The aim of this article is to describe a therapeutic approach used with a patient who suffered varying degrees of crown fractures in three teeth that were treated with adhesive fragment reattachment. The natural crown bonding technique, using tooth fragments and a direct composite resin, successfully restored all of the fractured anterior teeth. The clinical examinations showed good esthetics and periodontal health after a 14-month follow-up, proving that the technique is a good option for tooth fractures.

Diversity, frequency and antifungal resistance of Candida species in patients with type 2 diabetes mellitus.

OBJECTIVE: To determine number, species of Candida and Candida resistance to antifungal therapy according to the metabolic control state and the associated salivary changes in patients with type 2 diabetes mellitus (DM2). MATERIALS AND METHODS: Samples of non-stimulated saliva were collected from 52 patients with DM2. Salivary pH was measured and cultured on Sabouraud glucose agar and the values of CFU/ml were calculated. The species were presumptively identified using CHROMagar Candida® plates, and identification was confirmed by polymerase chain reaction (PCR). C. albicans isolates were cultured on SGA tetracycline agar with nystatin and fluconazole diffusion disks to measure susceptibility. RESULTS: Sixty six percent of the yeasts isolated were Candida albicans, followed by C. glabrata (20.7%). In patients with decompensated DM2, there was an inverse association between HbA1c value and salivary pH. At higher levels of salivary acidification, a greater diversity and quantity of yeasts of the genus Candida were observed. With nystatin, higher inhibition was observed at lower pH. CONCLUSIONS: The antifungal therapies could be more effective if it consider, qualitative salivary characteristics as pH, that could determine the susceptibility of species of Candida to at least to nystatin, which is the most used antifungal for treatment to oral candidiasis in patients with DM2.

Enxerto de tecido conjuntivo subepitelial e retalho coronal em recessões gengivais múltiplas / Subepithelial connective tissue graft and coronal fl ap in multiple gingival recessions

Algumas das principais indicações para o recobrimento de superfícies radiculares expostas por recessão gengival compreendem a hipersensibilidade dentinária cervical e o tratamento de defeitos estéticos. Este trabalho descreveu o tratamento de recessão gengival múltipla classe III de Miller em um periodonto delgado, após 36 meses de uma intervenção cirúrgica com enxerto gengival livre. O tratamento cirúrgico periodontal proposto foi o recobrimento radicular por meio de enxerto de tecido conjuntivo subepitelial associado a retalho reposicionado coronalmente na região vestibular dos elementos 31, 41 e 42. Após 90 dias, foi possível observar o recobrimento parcial da recessão, aumento da espessura tecidual e o controle do biofi lme pelo paciente, promovendo maior proteção da região e redução do risco de recidiva das recessões. Diante da resolução do caso clínico apresentado, pôde-se concluir que a técnica do enxerto de tecido conjuntivo subepitelial associado ao retalho reposicionado coronalmente, quando bem indicada e realizada, pode ser empregada com sucesso em áreas de recessões múltiplas e periodonto com espessura reduzida.

Some of the main indications for the root coverage of gingival recessions include cervical dentin hypersensitivity and treatment of aesthetic defects. This manuscript describes the treatment of a Miller's Class III multiple gingival recession 36 months after a free gingival graft surgical procedure. The periodontal surgical treatment proposed was the subepithelial connective tissue graft associated with a coronally repositioned fl ap at vestibular region of elements 31, 41 and 42. After 90 postoperative days, it was possible to observe an increase on tissue thickness and biofi lm control by the patient, promoting a greater protection of the region and reducing the risk of recession recurrence. It can be concluded that the subepithelial connective tissue graft technique associated with the coronal repositioned fl ap, when well indicated and performed, can be successfully used in multiple recessions and periodontal regions with reduced thickness.

Management of an uncomplicated crown fracture by reattaching the fractured fragment-Case report.

Coronal fractures of the anterior teeth are common sequelae of traumatic dental injuries. Reattachment of fractured tooth fragments using dental adhesive techniques offers some advantages, including restoration of the function, esthetics, shape, texture, and brightness of the surface. The present report describes a clinical case of reattachment with a 4-year clinical and radiographic follow up in a permanent maxillary central incisor with an uncomplicated crown fracture. Fragment reattachment is a conservative procedure, preserving esthetics and functionality, and it can provide an immediate positive emotional response from the patient.

Therapeutic Approach to Pulp Canal Calcification as Sequelae of Dental Avulsion.

Tooth avulsion represents the most complicated dental injury, and the classic treatment is tooth replantation. The most common sequelae are pulp canal calcification (PCC) and pulp necrosis. The presence of pulp necrosis after PCC is reported in up to 30% of the cases and is a challenge due to the difficulty of endodontic treatment. This case report describes the surgical treatment of a replanted tooth presenting PCC and periapical pathology eight years after the trauma. An endodontic surgery was performed to remove the apical granuloma, to prepare the apical root, and to seal the apical region with an endodontic cement. In a three-year follow-up, there was an absence of inflammatory signs and symptoms or apical lesion. This report shows the importance of close follow-up after dentoalveolar injuries. After the initial dental trauma and its consequences to pulpal tissues, the executed procedures allowed a favourable outcome.

Resolução de desarmonia gengival do arco superior durante tratamento ortodôntico através de cirurgia periodontal / Resolution of upper gingival arch disarmony during orthodontic treatment by periodontal surgery

A busca por padrões de sorriso que atendam aspectos visuais harmônicos inclui uma pequena exposição gengival. Na presença de um sorriso alto podemos observar a exposição total das coroas clínicas dos dentes anterossuperiores e uma faixa contínua de tecido gengival, podendo, este padrão clínico/periodontal, ser influenciado por sexo e idade, entre outros. O objetivo deste trabalho foi descrever um tratamento cirúrgico periodontal na região dos dentes anteriores superiores de uma paciente em tratamento ortodôntico com a finalidade de estabelecer uma estética periodontal satisfatória ao paciente. Concluímos que a intervenção cirúrgica periodontal visando o estabelecimento de contorno gengival e diminuição da linha gengival no sorriso alem do mostrou-se satisfatória no planejamento estético da paciente (AU)

The demand for smile patterns that meet visual harmonic aspects includes a small gingival exposure. In the presence of a high smile we can observe the total exposure of the clinical crowns of the anterior superior teeth and a continuous range of gingival tissue, and this clinical/periodontal pattern can be influenced by sex and age, among others. The objective of this study was to describe a periodontal surgical treatment in the region of the maxillary teeth in a patient with orthodontic treatment, in order to establish a satisfactory periodontal aesthetic for the patient. We conclude that the periodontal surgical intervention aiming at the establishment of gingival contour and reduction of the gingival line in the smile proved highly efficient in the aesthetic planning of the patient (AU)
