Efficacy and Safety of Oral Midazolam Sedation Compared with its Combination with Hydroxyzine Use in Pediatric Dentistry: A Systematic Review

ABSTRACT Objective: To assess the efficacy and safety of the use of midazolam as monotherapy, compared to the associated use of midazolam and hydroxyzine for minimum and moderate sedation of children in dental offices, using data obtained from clinical trials. Material and Methods: A systematic review protocol was developed and registered on PROSPERO (CR42020208633). An electronic search was carried out in Pubmed, Lilacs, Science Direct, Open Gray, Web of Science, and central Cochrane Library. No language restrictions were included. Clinical trials were carried out with children aged 0-12 years, using midazolam as monotherapy compared to the use of midazolam associated with hydroxyzine to verify the effectiveness and safety of oral sedation. The quality of the studies was individually assessed and grouped using the RoB 2 (Revised Cochrane risk-of-bias tool for randomized trials) and GRADE (Grading of Recommendations Assessment, Development and Evaluation) systems, respectively. Results: A total of 749 studies were found. After analyzing the inclusion and removal of duplicates, two studies were analyzed for the quality of evidence. Through this analysis, it was possible to verify the very low level of scientific evidence on the superiority of the efficacy and safety of the combined use of midazolam and hydroxyzine for oral sedation in children in dental offices. Conclusion: The conflicting results and limitations of the studies enabled to establish that there is insufficient evidence to support the use of these drugs combined. There is only evidence for the use of midazolam as monotherapy.

Dietary supplementation with multi-strain formula of probiotics modulates inflammatory and immunological markers in apical periodontitis.

OBJECTIVE: The aim of this study was to evaluate whether probiotics multi-strain formula affects the development of apical periodontitis (AP) induced in rats. METHODOLOGY: 16 Wistar rats were divided in two groups (n=8): rats with AP fed with regular diet (Control-C (CG)); rats with AP, fed with regular diet and supplemented with multi-strain formula (one billion colony-forming units (CFU)): GNC Probiotic Complex (PCG) ( Lactobacillus acidophilus, Lactobacillus salivaris, Lactobacillus plantarum, Lactobacillus rhamnosus, Bifidobacterium bifidum, Bifidobacterium animalis subs. lactis and Streptococcus thermofilus ). AP was induced in the upper and lower first molars by dental pulp exposure to the oral environment. PCG was administered orally through gavage for 30 days during the AP development. After this period the animals were euthanized and the mandibles were removed and processed for histologic analysis, and immunochemical assays for interleukin (IL)-6, IL-10, IL-1ß, RANKL, OPG, and TRAP. The Mann-Whitney U test and Student's t test were performed (P<.05). RESULTS: The CG showed more intense inflammatory infiltrate than the PCG group (P<.05). IL-1ß, IL 6 and RANKL decreased in the PCG group compared with CG (P<.05). The IL-10 level increased in the PCG group (P<.05). The OPG level was similar in both groups (P>.05). The number of mature osteoclasts (TRAP-positive multinucleated cells) was lower in PCG group when compared to the CG (P<.05). CONCLUSION: Probiotic Complex modulates inflammation and bone resorption in apical periodontitis.

Apicotomia associada ao tracionamento ortocirúrgico em dente com dilaceração radicular / Apicotomy associated with orto-surgical treatment in tooth with a root dilaceration

Introdução: A apicotomia é uma técnica, que vem sendo utilizada em dentes com dilaceração radicular acentuada, com o intuito de liberar a porção do dente impactada e, dessa forma, permitir seu reposicionamento na arcada dentária. Este trabalho tem como objetivo apresentar um relato de caso clínico do manejo ortocirúrgico de tracionamento ortodôntico associado à apicotomia em dente incluso com dilaceração radicular acentuada. Relato de caso: O paciente foi encaminhado para o serviço de bucomaxilofacial para exodontia do elemento incluso após insucesso de tracionamento ortocirúrgico, em que se verificou, ao exame radiográfico periapical, dente incluso com dispositivo ortodôntico e dilaceração radicular importante. Diante disso, realizou-se, sob anestesia local, a apicotomia e instalação do dispositivo ortodôntico. O paciente evoluiu bem, e, após 8 meses, o elemento dentário encontrava-se em posição oclusal e em função mastigatória. Considerações finais: Assim, a técnica da apicotomia mostra-se eficaz como alternativa ao insucesso do tracionamento ortodôntico tradicional, sendo uma técnica mais conservadora que a exodontia, necessitando de conhecimento teórico e domínio técnico do profissional...

Introduction: Apichotomy is a technique that has been used in teeth with severe root laceration in order to release the impacted tooth portion and thus allow its repositioning of the tooth in the dental arch. The aim of this paper is to present a clinical case report of orthosurgical orthodontic traction management associated with apichotomy in an included tooth with severe root laceration. Case report: The patient was referred to the Oral and Maxillofacial Service for extraction of the included element after ortho-surgical traction failure, which was verified by periapical radiographic examination, tooth included with orthodontic device and significant root laceration. Thus, under local anesthesia, apichotomy and orthodontic device installation were performed. The patient progressed well, and after 8 months the dental element was in occlusal position and in masticatory function. Final considerations: Thus, the apichotomy technique is effective as an alternative to the failure of traditional orthodontic traction, being a more conservative technique than extraction and requiring theoretical knowledge and technical mastery of the Professional...

Cemento-Osseous Dysplasias: Imaging Features Based on Cone Beam Computed Tomography Scans

Abstract Imaging exams have important role in diagnosis of cemento-osseous dysplasia (COD). Cone beam computed tomography (CBCT) stands out for allowing three-dimensional image evaluation. This study aimed to assess the prevalence of cases diagnosed as COD on CBCT scans, as well identify the main imaging features related to these lesions. An analysis was performed in a database containing 22,400 radiological reports, in which all cases showing some type of COD were initially selected. These CBCT exams were reevaluated to confirm the radiographic diagnosis and determine the prevalence and distribution of the types of COD with regard to gender, age and preferred location, while describing its most common imaging aspects. Data were presented using descriptive analyses. There were 82 cases diagnosed as COD in the CBCT images (prevalence of 0.4%). The distribution of patients was 11 (13.4%) male and 71 (86.6%) female, with a mean age of 49.8 years (age-range 17-85 years). There were 47 (57.3%) cases of periapical COD, 23 (28%) of focal COD and 12 (14.6%) of florid COD. The mandible was more affected than the maxilla. In most cases, the lesions were mixed or hyperdense. All COD had well-defined limits and there were no cases of tooth displacement. In conclusion, periapical COD was the most common type and the most affected bone was the mandible. Imaging evaluation is critical for diagnosis and dentists should bear in mind all possible radiographic presentations of COD in order to prevent misleading diagnoses and consequently, inadequate treatments.

Resumo Os exames por imagem têm papel importante no diagnóstico da displasia cemento-óssea (DCO). A tomografia computadorizada por feixe cônico (TCFC) se destaca por permitir a avaliação tridimensional da imagem. O objetivo neste estudo foi avaliar a prevalência de casos diagnosticados como DCO nos exames de TCFC, bem como identificar as principais características de imagem relacionadas a essas lesões. Uma análise foi realizada em um banco de dados contendo 22.400 laudos radiológicos, no qual todos os casos que apresentavam algum tipo de DCO foram inicialmente selecionados. Estes exames foram reavaliados para confirmar o diagnóstico radiográfico e determinar a prevalência e distribuição dos tipos de DCO em relação ao sexo, idade e localização preferencial, além de descrever seus aspectos imaginológicos mais comuns. Os dados foram apresentados por meio de análise descritiva. Oitenta e dois casos foram diagnosticados como DCO nas imagens de TCFC (prevalência de 0,4%). A distribuição dos pacientes foi de 11 (13,4%) homens e 71 (86,6%) mulheres, com idade média de 49,8 anos (faixa etária de 17 a 85 anos). Houve 47 (57,3%) casos de DCO periapical, 23 (28%) de DCO focal e 12 (14,6%) de DCO florida. A mandíbula foi mais afetada que a maxila. Na maioria dos casos, as lesões foram mistas ou hiperdensas. Todas as DCO apresentaram limites bem definidos e não houve casos de deslocamento dentário. Em conclusão, a DCO periapical foi o tipo mais comum e o osso mais afetado foi a mandíbula. A avaliação da imagem é crítica para o seu diagnóstico e os dentistas devem ter em mente todas as possíveis apresentações radiográficas da DCO, a fim de prevenir diagnósticos enganosos e, conseqüentemente, tratamentos inadequados.

Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats.

OBJECTIVE: This study aimed to assess the effects of fluoxetine, a selective serotonin reuptake inhibitor, on the formation of the periodontal ligament during pregnancy and lactation in rat pups. MATERIAL AND METHODS: Twelve pregnant rats of Wistar lineage were divided into four study groups. In the control group, 0.9% sodium chloride solution was administered orally, throughout the entire period of the 21 days of pregnancy (CG group) and in the CGL group, it was administrated during pregnancy and lactation (from day 1 of pregnancy to the 21st day after birth). Fluoxetine was administered orally at the dose of 20 mg/kg in a group treated during pregnancy only (FG group), and during pregnancy and lactation (FGL group). Histometrical, histochemical and immunohistochemical analysis of the maxillary first molar periodontium region of the 24 rat pups was made under light microscopy, and periodontal ligament collagen was qualitatively evaluated under a polarizing light microscope. RESULTS: The quantity of fibroblasts (p=0.006), osteoblasts (p=0.027) and cementoblasts (p=0.001) was reduced in pups from the rats that received fluoxetine during pregnancy and lactation. No alterations were seen in the collagen fibers. CONCLUSION: These findings suggest that periodontal tissue may be sensitive to fluoxetine, and its interference in reducing periodontal cells depends on exposure time during lactation.

Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats

Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development.
