Modified Approach to Central Giant Cell Lesion.

This case report discusses a modified technique for treatment of a central giant cell lesion (CGCL) in children, where a recontouring procedure is performed prior to the treatment with intra lesional corticosteroid. We discuss the advantages of this less invasive technique, specially considering the early age of the patient and its bone growth, as well as the conservative approach for lesions in those cases. The treatment of an 8-year-old female patient exhibiting CGCL in anterior region of mandible with bone expansion is described. The procedure was performed using blade #15 and rongeur forceps, in order to obtain an adequate jaw contour. Two weeks later, drug treatment started with triamcinolone 10mg/ml diluted in 0.5% bupivacaine without vasoconstrictor agent, 1:1 ratio, for eight sessions. There were no complications in surgery and postoperative period. In 3-year follow-up, anatomical preservation is present with no signs of recurrence.

The Use of Antibiotics in Odontogenic Infections: What Is the Best Choice? A Systematic Review.

PURPOSE: Odontogenic infections are a common problem in dentistry, and their treatment often requires the use of antibiotics besides the removal of the source of infection, which frequently makes it more difficult for clinicians to make a decision regarding the choice of antibiotic. This study aimed to answer the following questions through the Patient, Intervention, Comparison, Outcome (PICO) format: When should antibiotics be used in dental infections (DIs)? Which are the most effective drugs? How long should antibiotics be administered? MATERIALS AND METHODS: This was a systematic review using the PubMed, Scopus, and Cochrane databases without restriction as to the period researched. The variables analyzed in each article were the number of odontogenic infections in each study, type of study, surgical intervention performed, antibiotics administered, statistical differences between groups studied, and patients' evolution after treatment. RESULTS: The search included 1,109 articles. After the full reading of 46 articles, 16 were included in the final review and 30 were excluded. A sample of 2,197 DI cases was obtained, in which 15 different antibiotics were used, with a 98.2% overall cure rate. CONCLUSIONS: The studies showed that antibiotics were prescribed only in situations of regional and/or systemic body manifestations. In the case of DIs, once drainage has been performed and/or the cause of infection has been removed, all antibiotics tested are equally effective with respect to clinical cure, and the choice of antibiotics is not as successful as the local intervention treatment procedure. When the real need for antibiotic therapy is detected, antibiotics should be used for the shortest time possible until the patient's clinical cure is achieved.

Primary incisor intruded through the nasal cavity: a case report.

Intrusive luxation may cause complications for the primary tooth and generate adverse sequelae in the permanent successor. Although intrusion is prevalent in the primary dentition, full intrusion is a rare event that requires specialized treatment and a multidisciplinary approach. This article describes the case of a 1-year-old girl who presented with traumatic displacement of the maxillary left central incisor into the nasal cavity. The parents sought treatment 1 month after the child sustained the injury, and the impacted tooth was removed through her left nostril under general anesthesia. Four-year clinical and radiographic follow-up revealed no adverse sequelae.

What is the effect of lactoferrin on oral and jawbone tissue repair? A systematic review.

Currently, there is growing interest in the potential use of lactoferrin (LTF), a member of the transferrin family, for the improvement of tissue healing. In this sense, a literature search was conducted to integrate data published on the effect of LTF on jawbone repair. PubMed/MEDLINE, Scopus, Embase, Web of Science, LILACS, and Cochrane databases were retrieved according to the PRISMA 2020 statement. Articles in English, Spanish, and Portuguese were recovered, with no year restriction. In vitro, in vivo, and clinical studies were selected. A total of 742 articles were retrieved, 11 of which met the inclusion criteria (5 in vitro and 5 in vivo studies, and one clinical trial). The included data demonstrated wide variations in study design and LTF therapy protocols. Cell proliferation and viability were the primary outcomes evaluated in the in vitro studies, all of which reported a potential effect of LTF on the repair process. Of three in vivo studies, one reported a reduction in the overall healing rate, whereas the other two showed that LTF inhibited bone resorption and increased bone formation. The clinical trial's findings showed that LTF is a potential promoter of wound repair in patients with medication-related osteonecrosis of the jaws. Overall, data from the studies support a potential effect of LTF therapy on the process of jawbone repair.

Central incisor impacted by an odontoma.

AIM: The aim of this report is to present a clinical case of impaction of a maxillary left central incisor in a mixed dentition caused by the presence of an odontoma as well as a review of the pertinent dental literature. BACKGROUND: Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occur within a normal time frame, the tooth is not present in the dental arch, and there is no potential for eruption due to the presence of a completely formed root or when the homologous tooth has been erupted for at least six months with complete root formation. REPORT: A 10-year-old boy in the mixed dentition stage presented with an impacted maxillary left central incisor due to the presence of an odontoma. Treatment included the surgical removal of the lesion and the follow up of the spontaneous eruption while a partial fixed appliance was used to recover the space of the missing tooth. Since spontaneous eruption failed to occur within the expected time frame, surgical exposition of the crown and bonding of an orthodontic appliance for traction was done to facilitate eruption. SUMMARY: The incisor was integrated to the dental arch without any root or periodontal sequelae. The treatment was considered a success, since both health and aesthetics of the smile were recovered. The importance of the clinical and radiographic diagnosis of the retention of a permanent tooth associated with a pathological entity should be emphasized. The participation of a multidisciplinary team to accomplish the appropriate treatment of such patients is extremely relevant because of the esthetic and functional ramifications of a missing anterior tooth as well as the psychological well-being of the individual.

Surgical Treatment of Fibroosseous Lesion in Young Patient with Reduced Mouth Opening.

Fibrous dysplasia is a benign fibroosseous disorder that can affect the maxillary bones, causing aesthetic deformity and functional impairment. This article reports the case of a 13-year-old male patient at the time of diagnosis. The patient showed increased facial volume with relevant asymmetry, having reported the onset of the condition 12 months before. Upon examination, the patient presented an 8-mm mouth opening and an acute inflammatory process associated with tooth 37 pericoronal hood. Upon imaging exam, exuberant bone growth in the left mandibular ramus area of ground glass aspect was observed. After incisional biopsy, fibrous dysplasia was diagnosed and sequentially treated with osteoplasty and coronoid process removal. The patient evolved to a 43-mm mouth opening and favorable aesthetics without recurrence in a 3-year follow-up period. In this case, coronoidectomy and bone plasty proved to be effective, returning aesthetics and function. The patient is supposed to be followed up in the long term.

Etiology, diagnosis, and demographic analysis of maxillofacial trauma in elderly persons: A 10-year investigation.

PURPOSE: The aim of this study was to investigate etiologies and diagnoses of maxillofacial trauma in emergency services in Brazil over a period of 10 years. Additionally, associations among sex, age, accident location, and dependent variables were analyzed. Understanding the epidemiology of trauma and the physiology of aging is important in maintaining health and bettering service for the elderly population. MATERIALS AND METHODS: The primary mode of investigation was analysis of medical records from 2003 to 2013. These researchers recorded the diagnosis and etiology of the trauma, the location where the accident occurred, and the sex and age of the participants. Variable categories were compared using Chi-squared distribution, and logistic regression was used to analyze the associated factors. RESULTS: Of the 677 individuals analyzed, the female sex was predominant (57.61%) and the most prevalent age ranges were between 60 and 69 years (40.18%) and between 70 and 79 years (35.16%). Chi-squared distribution showed that men suffered more fractures (18.47%, p = 0.028) and women suffered more contusions (21.54%, p = 0.028). With regard to the various etiologies related to the traumas, traffic accidents (17.77%, p < 0.001) and aggression (17.42%, p < 0.001) were more frequent in males, and falls (83.03%, p < 0.001) were more frequent in females. The primary etiologies for maxillofacial trauma in the elderly population were falls, and the primary diagnoses were fractures. CONCLUSION: A deeper understanding of the physiological changes associated with aging, and preventive action to reduce falls, traffic accidents, and aggression in this population could be beneficial with regard to quality of life for elderly persons.

Intralesional corticosteroid injection for central giant cell granuloma: an alternative treatment for children.

The purpose of the present article was to report a case of central giant cell granuloma (CGCG) associated with intralesional corticosteroid injections. Although benign, the CGCG may be locally aggressive, causing extensive bone destruction, tooth displacement, and root resorption. The common therapy is surgery, which may result in important facial deformity and loss of teeth or dental germs. In this article, an 8-year-old girl who presented with maxillary CGCG was treated with a solution of equal parts of triamcinolone actinide (10 mg/ml) and 0.5% bupivacaine injected into the lesion for a period of 11 weeks. The osseous neoformation was gradual. After 6-years follow-up, clinical and radiographic success of treatment were observed. Based on our results and the literature available, the administration of intralesional corticosteroid injections is an alternative in CGCG treatment, especially in children.

Keratoacanthoma in the cutaneous area of the upper lip: a case report / Ceratoacantoma em região cutânea de lábio superior: relato de caso

PURPOSE: The aim of this paper is to briefly review and discuss the literature about KA and present a case report with a 2-year follow-up of the removal of a KA lesion in the upper lip. CASE DESCRIPTION: A 53-year-old woman complained of a painless, aesthetically unpleasant brownish, hard lesion in the cutaneous area of the upper lip. The lesion had grown rapidly in the last 30 days (size: ~10×5 mm), and was associated with a hot waxing hair removal. Surgical excision was the treatment chosen in order to differentiate the lesion from squamous cell carcinoma (SCC). An oval-shaped incision was created with an in-depth wedge shape for the removal of the lesion and better approximation of the edges after synthesis. Histopathological analysis confirmed the diagnosis of KA. After 2 years, the patient was completely satisfied with the treatment, and no scar was evident. CONCLUSION: Due to the clinical difficulty in differentiating KA from SCC and the risk for formation of an aesthetically unpleasant scar upon spontaneous resolution of KA, surgical removal might be considered the treatment of choice for a solitary KA.

OBJETIVO: O objetivo deste trabalho é revisar e discutir brevemente a literatura sobre CA e apresentar o relato de um caso da remoção de CA em lábio superior com 2 anos de acompanhamento. DESCRIÇÃO DO CASO: Mulher com 53 anos queixava-se de lesão indolor, esteticamente desagradável, dura e de coloração marrom na área cutânea do lábio superior. A lesão havia crescido rapidamente nos últimos 30 dias (tamanho: ~10×5 mm), e estava associada à remoção de pêlos com cera quente. Excisão cirúrgica foi o tratamento escolhido para diferenciar a lesão de carcinoma espinocelular (CEC). Uma incisão em forma oval aprofundada em forma de cunha foi realizada para remoção da lesão e melhor aproximação das bordas após a síntese. A análise histopatológica confirmou o diagnóstico de CA. Após 2 anos, a paciente estava completamente satisfeita com o tratamento, e nenhuma cicatriz era evidente. CONCLUSÃO: Devido à dificuldade na diferenciação clínica entre CA e CEC, e o risco de formação de cicatriz esteticamente desagradável quando da resolução espontânea do CA, a remoção cirúrgica pode ser considerada o tratamento de escolha para CA solitário.

Osteoma periférico mandibular: relato de caso / Mandibular peripheral osteoma: case report

Osteomas são tumores benignos compostos de osso maduro compacto ou esponjoso, podendo apresentar-se clinicamente na periferia, intraósseo, ou no interior dos tecidos moles. São essencialmente restritos ao esqueleto craniofacial, ocorrendo com maior frequência na mandíbula, sendo raramente diagnosticados em outros ossos. A variável osteoma periférico apresenta-se como uma massa óssea pediculada, de crescimento lento, assintomática, isolada e unilateral. Sua frequência é maior em homens, entre a segunda e quinta décadas de vida, sendo sua etiopatogenia amplamente discutida, podendo ser de origem reacional, traumatológica, inflamatória, ou alteração na fisiologia óssea. Comumente esta lesão está associada a pacientes portadores da Síndrome de Gardner. Objetiva-se, através de relato de caso clínico, discutir a causa, aspectos clínicos, radiográficos e histológicos desta neoplasia, assim como seu tratamento.

Osteomas are benign tumors composed of compact or cancellous mature bone, which may present clinically in the periphery, intra-bone or inside soft tissues. They are essentially restricted to craniofacial skeleton, occurring more frequently in the jaw, rarely diagnosed in other bones. The variable peripheral osteoma usually presents as a pedicled bone mass, of slow growth, asymptomatic, isolated, and unilateral. It is more frequently found in men, between the second and fifth decades of life, being its etiopathogenesis widely discussed, its origin may be reactive, inflammatory, from trauma or physiological bone changes. These lesions are commonly associated with patients with GardnerÆs Syndrome. Through a case report this study aims to discuss cause, clinical, radiographic and histological aspects of this neoplasm, as well as its treatment.

Oroantral communication closure using a pedicled buccal fat pad graft / Fechamento de comunicação buco-sinusal utilizando enxerto pediculado de corpo adiposo da bochecha

Purpose: This paper reports the procedure used to close a late oroantral fistula using rotating flaps of the pedicled buccal fat pad. Case description: A 66-year-old, male patient with leukoderma, in good general health, was referred for closure of an extensive late oroantral communication. Upon clinical examination, an approximately 10-mm fistula was observed connecting the oral cavity to the maxillary sinus. An outpatient surgical procedure was performed with the use of local anesthetics to close the oroantral fistula with a rotating pedicled buccal fat pad flap. The healing of the wound and closure of the defect could be seen after a 30-day postoperative period, with complete epithelialization. Conclusion: Grafting of the pedicled buccal fat pad is thought to be an efficient, safe and easy alternative to a larger oroantral fistula closure. Pedicled buccal fat pad grafting corrected the defect without generating any sequelae and/or great postoperative discomfort to the patient.

Objetivo: O objetivo deste artigo foi relatar um caso clínico de fechamento de fístula buco-sinusal tardia utilizando rotação de enxerto de tecido adiposo pediculado do corpo adiposo da bochecha. Descrição do Caso: Paciente do sexo masculino, 66 anos, leucoderma, em boas condições de saúde geral, foi encaminhado para fechamento de extensa comunicação buco-sinusal. Ao exame clínico, observou-se uma fístula de aproximadamente 10 mm de diâmetro comunicando a cavidade oral com o seio maxilar. A cirurgia foi realizada em nível ambulatorial, sob anestesia local, para fechar a fístula buco-sinusal com um enxerto de tecido adiposo pediculado do corpo adiposo da bochecha. A reparação da ferida e o fechamento do defeito foram observados no pós-operatório de 30 dias, com completa epitelização. Conclusão: O enxerto pediculado de tecido do corpo adiposo da bochecha mostrou-se uma alternativa simples, eficaz e segura no fechamento mediato da fístula buco-sinusal apresentada neste caso clínico.
