Objective This study aimed to analyze the effectiveness of three irrigation systems: EndoActivator, passive ultrasonic irrigation (PUI), and Easy Clean in the reduction of Enterococcus faecalis, after instrumentation with the reciprocating system, through microbiological collection and culture method. Materials and Methods A total of 60 extracted human lower premolars were used and standardized at 16 mm in length. The teeth were accessed, contaminated with E. faecalis, and incubated for 21 days at 37°C. Initial collections (S1) were made with an absorbent paper cone to confirm the contamination; subsequently, instrumentation was performed with WaveOne Primary. The teeth were divided into four groups according to the final irrigation protocol (n = 15): group 1. EndoActivator; group 2, PUI; group 3, Easy Clean; and group 4, control group irrigated with saline solution sterile and without agitation. In the final irrigation, the agitation of the 17% ethylene amine tetra-acetic acid (EDTA) solutions was used, then 2.5% sodium hypochlorite (NaOCl); in both for this, three cycles of 20 seconds each. After the chemical–mechanical preparation and agitation of the irrigating solutions, the final collections (S2) for counting the colony-forming units (CFU/mL) occurred. Results The Kruskal–Wallis test revealed that all the agitation systems reduced by 100% and the control group by 65.7%. Conclusion The control group presented a significantly higher amount of CFU/mL after the chemical–mechanical preparation than the other groups, which were similar to each other (p > 0.05).

Material e Método: Foi realizada uma revisão da literatura em livros e bases de dados eletrônicos. Resultados: Os pacientes soropositivos podem desenvolver várias lesões bucais e peribucais, que não são únicas para portadores do HIV, mas ocorrem em maior frequência quando associadas a imunossupressão. As mais prevalentes são Infecções
ResumoA terapia endodôntica de dentes com morte pulpar e rizogênese incompleta é complexa representando um desafio aos endodontistas, exigindo muita habilidade profissional. E para esses casos, uma alternativa promissora vem sendo muito utilizada, conhecida como regeneração ou revascularização pulpar. Esta técnica é menos invasiva quando comparada a técnica tradicional (apicificação), sendo que na revascularização pulpar por meio de um estímulo ocorre a invaginação de um novo tecido para o interior do canal, permitindo assim a regeneração dos tecidos danificados, devolvendo suas condições fisiológicas de vitalidade. O objetivo deste trabalho será descrever um tratamento de revascularização em um dente permanente jovem com ápice aberto que sofreu necrose pulpar após a ocorrência de um trauma. Conclusão: De acordo com os resultados obtidos; concluímos que houve regressão completa de sintomatologias, involução da fístula sem recidiva, resposta positiva ao teste de vitalidade pulpar, além do contínuo desenvolvimento radicular e regeneração do tecido danificado, comprovando assim a efetividade da técnica.

AbstractEndodontic therapy of teeth with pulp death and incomplete rhizogenesis is complex, posing a challenge to endodontists, requiring a great deal of professional skill. And for these cases, a promising alternative has been widely used, known as regeneration or pulpal revascularization. This technique is less invasive when compared to the traditional technique (apicification), and in pulpal revascularization by means of a stimulus, the invagination of a new tissue into the canal, thus allowing the regeneration of the damaged tissues, returning their physiological conditions of vitality. The objective of this work will be to describe a treatment of revascularization in a permanent young tooth with open apex that suffered pulp necrosis after the occurrence of a trauma. Conclusion: According to the results obtained; we conclude that there was complete regression of symptoms, involution of the fistula without recurrence, positive response to the pulp vitality test, as well as the continuous root development and regeneration of the damaged tissue, thus proving the effectiveness of the technique.

ResumoO Fibroma Ossificante Periférico é uma lesão nodular caracterizada como hiperplásica inflamatória reacional sendo considerada uma das patologias bucais mais comuns, ocorre quase que exclusivamente na gengiva inserida e geralmente envolve a papila interdental. É uma entidade patológica que suscita muitas controvérsias em relação à sua natureza, pois tem etiologia desconhecida. Cálculos dentais, placa bacteriana, próteses mal adaptadas e outros fatores iatrogênicos, alimentos duros durante a mastigação, deglutição e fala, são considerados fatores irritantes gengivais podendo influenciar neste crescimento reacional. Apresenta como aspecto histopatológico mais marcante a presença de calcificações em várias formas e tamanhos. O exame radiográfico é de grande valor para o diagnóstico, visto que focos radiopacos centrais, podem estar associados ou não a discreta reabsorção da crista do rebordo em sua base. Estudos radiológicos, em alguns casos, mostram na massa de tecido mole área de calcificação. O propósito deste trabalho foi relatar um caso clínico de fibroma ossificante periférico, suas características clínicas, radiográficas e histopatológicas, reforçando a importância dos exames complementares no diagnóstico desta patologia. Concluiu-se que o fibroma ossificante periférico é uma lesão reacional da gengiva, nodular e assintomática. Necessita de exame histopatológico para a confirmação do diagnóstico. O exame radiográfico é de grande importância, pois dependendo da fase de desenvolvimento da lesão esta pode apresentar-se com discretos pontos de calcificações, sem envolvimento do osso subjacente. Descritores: Paracoccidioidomicose; Mucosa bucal; Manifestações Bucais; Epidemiologia. AbstractPeripheral ossifying fibroma is a nodular lesion characterized as inflammatory and hyperplasic reaction. It is considered one of the most common oral diseases and occurs almost exclusively in the attached gingiva. Usually involves the interdental papillae. It is a pathological entity that raises many controversies regarding their nature, although the unknown etiology. Dental calculus, plaque, illfitting dentures and other iatrogenic factors, food during chewing, swallowing and speaking are considered gingival irritants and may influence this reaction growth. The differential diagnosis is made with the fibrous hyperplasia, peripheral giant cell lesion and pyogenic granuloma. Only clinical findings are not sufficient for the diagnosis of peripheral ossifying fibroma, as both their clinical appearance as developments may be similar to pyogenic granuloma and peripheral granuloma and giant cells. The most striking histologic features is the presence of calcifications. Radiographic examination is useful for the diagnosis, since central radiopaque areas corresponding to mineralization, with or without discrete resorption rim crest in its base, can be identified. Radiologic studies, in some cases, show the mass soft tissue calcification area. This study was to report a case of peripheral ossifying fibroma, their clinical and radiogr...
Objective: The objective of the present review was to relate the scientific production presented in the last 5 years on the effect of photodynamic therapy using the methylene blue photosensitizer on the microorganisms present in the oral biofilm. Methods: systematic review looking for research in English of primary studies such as randomized clinical trials and without randomization, individual case-control, and qualitative descriptive studies, using the PubMed/MEDLINE and Scopus databases as references, from 2017 to 2021. Results: 15 articles were analyzed, being 67% national publications and 33% international studies. Considering the samples described in the studies, 73% were in vitro, 7% were in vivo and 20% were clinical samples. As for the light source, 66% used laser, 20% used LED and 14% the association of laser and LED devices. The power density used ranged from 0.0026 W/cm2 to 1415 W/cm2. The energy density ranged from 3 J/cm2 to 640 J/cm2. The power ranged from 10 mW to 110 mW. The irradiation time ranged from 24 to 294 seconds. In most publications, 87% used the wavelength of 660 nm. As for the photosensitizer, the most used concentration, in 33% of the studies, was 0.01%, with the pre-irradiation time most used being 300 seconds in 40% of the studies. Conclusion: Photodynamic Methylene Blue Therapy is being accepted as effective in therapies of various oral curative conditions and has been shown to be a useful and effective therapy, as well as a complementary approach to control the development/growth of oral biofilm in clinical situations.
