ResumoObjetivo: Caracterizar os pacientes atendidos e os procedimentos realizados no Serviço de Atendimento a Pacientes com Necessidades Especiais da Faculdade de Odontologia de Araraquara (FOAr) -UNESP. Metodologia: A partir dos prontuários odontológicos dos pacientes atendidos em nível ambulatorial entre 2007 e 2013, foram obtidas informações em relação a idade no início do tratamento, tipo de deficiência, medicamentos usados, número de sessões de atendimento e número e tipo de procedimentos odontológicos realizados. Resultado: Dos 232 prontuários analisados, observou-se que mais da metade dos pacientes (56,0%) apresentava deficiência mental, paralisia cerebral ou anomalias congênitas determinadas por agentes infecciosos, com deficiência mental associada. Entre as anomalias congênitas, a mais prevalente foi a Síndrome de Down (9,9%). Apenas 20% dos pacientes iniciaram o tratamento antes dos dez anos de idade e 62,0% faziam uso de anticonvulsivantes, antipsicóticos, ansiolíticos, antiepilépticos e antidepressivos. Foram realizados 4.506 procedimentos odontológicos, sendo 37,6% preventivos e 62,4% curativos (Restauradores, 28,0%; Periodontais, 13,9%; Endodônticos, 9,7%; Cirúrgicos, 9,1%; Protéticos, 1,7%). Observou-se também que, para a maior parte dos pacientes (63%), foram necessárias até dez sessões para a realização do tratamento. Conclusão: Os pacientes que procuraram tratamento odontológico no Serviço de Atendimento a Pacientes com Necessidades Especiais da FOAr apresentavam, na sua maioria, deficiências com envolvimento neurológico. Apesar de esse serviço priorizar os procedimentos preventivos, a maior parte dos procedimentos executados foi curativa, o que está diretamente relacionado com a procura tardia pelo tratamento odontológico.Descritores: Pessoas com deficiência; assistência odontológica para pessoas com deficiências; uso de medicamentos. AbstractObjective: To characterize the patients and dental procedures performed in Service to Patients with Special Needs of Araraquara School of Dentistry (FOAr) -UNESP. Methodology: From the dental records of patients treated at outpatient basis between 2007 and 2013, information regarding age at the beginning of treatment, type of disability, controlled medications used, number of dental sessions, and number and type of dental procedures performed was obtained. Result: Of the 232 records analyzed, more than half of the patients (56.0%) had mental retardation, cerebral palsy or congenital abnormalities caused by infectious agents associated with mental retardation. Among the congenital abnormalities, the most prevalent was the Down syndrome (9.9%). Only 20% of patients started treatment before the age of ten and 62.0% used anticonvulsants, antipsychotics, anxiolytics, antidepressants and antiepileptics. A total of 4,506 dental procedures were performed, 37.6% were preventive procedures and 62.4% curative procedures (restorative, 28.0%; periodontal, 13.9%; endodontic, 9.7%; surgical, 9.1%, and prosthetic 1.7%). Also was observed that for most patients (63%) up t...

Reduced salivary flow rate might be an important factor in oral diseases development. High salivary levels of SOD and MDA show the significant influence of the oxidative stress and the early-onset periodontal disease in DS people.

Aim: To study influence of the cooling rate after sintering a veneering porcelain (Vita VM9) on fracture toughness by indentation strength (IS) and single-edge-v-notched beam (SEVNB) methods. Methods: Vita VM9 bars were sintered according to the manufacturer’s recommendation and cooled under three conditions: Slow (inside the furnace from sintering temperature to room temperature); Normal (inside the furnace from sintering temperature to 500 ºC and outside the furnace from 500 ºC to room temperature); and Fast (outside the furnace from sintering temperature to room temperature). Fracture toughness was measured by IS (n=10) and SEVNB (n=10) methods. Data were analyzed by two-way ANOVA (α=0.05). Results: The fracture toughness obtained from SEVNB (slow - 1.02±0.10; normal - 1.09±0.13; and fast - 1,02±0.18 MPa.m1/2 cooling techniques) was significantly lower than IS (slow - 1.19±0.13; normal - 1.17±0.07; and fast - 1.16±0.06 MPa. m1/2 cooling techniques). There was no significant influence of the cooling technique (p=0.012). Conclusions: The measurement technique influenced the fracture toughness values . IS method overestimated the fracture toughness values. Irrespective of the measuring method, cooling rate did not influence the Vita VM9 veneering porcelain fracture toughness.

Slow cooling seems to affect the veneer resistance and adhesion to the zirconia core; however, the reliability of fast cooling was slightly lower than that of the other methods.

Introduction Glass ionomer cements are often used as a base or cavity lining prior to restorative material. Objective To evaluate the bond strength of a composite resin to different glass ionomer cements, when using a two-step conventional and self-etching adhesive systems. Material and method Three glass ionomer cements (Ketac Molar Easymix, Vitremer and Vitrebond), the composite resin Filtek Z350 XT and the adhesive systems Adper Single Bond 2, Clearfil SE Bond and Adper Easy One were used. As negative control, resin was bonded to cement without using an adhesive system. Holes (4 mm diameter, 2 mm deep) prepared in acrilic bloks were filled with the glass ionomer cements (n=12/group). On the surface, an area of 1mm in diameter was delimited, the adhesive system was applied, and a specimen of composite resin with 1 mm height was made. After 24 hours storage (37 °C and 100% humidity), the microshear test was performed. Data were analyzed using two-way ANOVA and Tukey test for comparison between groups (α=0.05). Result The adhesive systems significantly improved the bond strenght of composite resin to glass ionomer cements (p≤0.001). There was no significant difference in bond strength when self-etching adhesive systems were compared with the simplified etch-and-rinse adhesive, except for Vitrebond where Clearfil SE Bond determined higher bond strength when compared to Adper Single Bond 2 (p=0.003). Conclusion Self-etching adhesive systems are a good option for establishing the bond between the composite resin and the glass ionomer cement.

This study aimed to present a bibliometric analysis about the central topic bruxism and disabled people in a global panorama through PubMed database (1965-2021). It was included in this study only journal publications in English. Letters to editor, short communication, articles irrelative to people with disabilities and bruxism or articles with unavailable abstract or full text were not included. The initial search was performed by three independent investigators who assessed the title, abstract and main text to determine the included or excluded articles. It was observed that the tendency of publications was rising, with an average of 1.9 per year. There were 27 countries that have contributed to publications on the studied field and the most productive ones are United States (28.2%) and Brazil (20.0%). The most productive authors in the field are Brazilian and among the most productive institutions, 4 are Brazilian and 3 are North American. Case reports were the most frequent type of article (28.1%), followed by cross-sectional studies (24.5%) and literature reviews (12.7%). The most productive journal in the studied field were Special Care in Dentistry (12.7%), followed by Journal of Oral Rehabilitation (3.6%). Brazil has a great scientific contribution to the field with a relevant number of publications, leading authors and institutions. There is a lack of high-quality evidence involving the main topic, reinforcing that further interventional studies and controlled trials must be conducted.

Juvenile Recurrent Parotitis (JRP) is an inflammatory condition characterized by recurrent parotid gland inflammation episodes of non-suppurative and non-obstructive nature. This is the second most common salivary disorder in childhood. We present a case of a 5-yearold girl with a recurrent facial swelling on the left side. Panoramic x-ray image excluded any dental or osseous involvement, as well as the presence of sialoliths. Ultrasonography showed hyperechoic focal areas with cavitation of the parotid gland corresponding to sialectasis. Sorological tests for infections like HIV, cytomegalovirus, mumps and other chronic diseases were negative. Based on the clinical and laboratorial features, the diagnosis was compatible with JRP. After two months of follow-up, the patient returned without any swelling or symptomatology. Seven months later, the patient returned with a new facial swelling episode, and this time on the right side. Clinicians should be aware of this condition and include in the differential diagnosis of salivary gland diseases of pediatric patients.

Introdução: O bruxismo do sono caracteriza-se como uma disfunção originada no sistema nervoso central que desencadeia a atividade muscular involuntária e repetitiva que pode promover o desgaste do dente. Objetivo: Realizar uma revisão de literatura a fim de descrever os fatores etiológicos associados ao bruxismo do sono em crianças. Método: Foram utilizadas as bases de dados PubMed, Scielo e Google Acadêmico, utilizando a combinação das palavras chaves: “bruxismo” ou “bruxism”, “bruxismo do sono” ou “sleep bruxism”, “crianças” ou “children”, “etiologia” ou “etiology” e “fatores de risco” ou “risk factors”. Resultados: Foram identificados trabalhos que apresentaram resultados relacionados aos fatores psicológicos, que podem ser enquadrados os transtornos de ansiedade, estresse, depressão e alterações comportamentais. Além disso, alterações sistêmicas como asma, obstrução de vias aéreas superiores, apnéia obstrutiva do sono, e refluxo gastroesofágico. Conclusão: O bruxismo possui origem multifatorial e pode ser desencadeado por fatores intrínsecos e extrínsecos ao paciente.
