Resumo O objetivo deste estudo foi avaliar associação entre dor pré-operatória, ansiedade e impacto da condição bucal na qualidade de vida dos pacientes atendidos no serviço de Urgência Odontológica da Universidade Federal dos Vales do Jequitinhonha e Mucuri. Estudo transversal retrospectivo foi conduzido avaliando dados clínicos de 240 prontuários de pacientes com idades entre 18 e 65 anos. A dor foi mensurada pela Heft-Parker Visual Analogue Scale; ansiedade, pela Corah's Detal Anxiety Scale e qualidade de vida, pelo Oral Health Impact Profile (OHIP-14). Associações foram analisadas pelo Teste qui-quadrado de Pearson (p < 0,05). Foi observada associação estatisticamente significante entre dor e pior qualidade de vida, com impacto nos domínios desconforto psicológico (p < 0,001), incapacidade física (p < 0,001), psicológica (p < 0,001) e social (p < 0,001). Ansiedade influenciou na pior qualidade de vida, com impacto nos domínios desconforto psicológico (p = 0,009), incapacidade fisica (p = 0,016), psicológica (p = 0,011) e desvantagem social (p = 0,028). Esse estudo é relevante para o planejamento de ações voltadas para a saúde bucal dos pacientes atendidos nos serviços de urgência odontológica, priorizando aqueles com maiores impactos psicossociais decorrentes dos problemas bucais.

Abstract The scope of this study was to assess the association between preoperative pain, anxiety and the impact of the oral condition on the quality of life of patients treated at the Dental Emergency Service at the Federal University of the Jequitinhonha and Mucuri Valleys. A retrospective cross-sectional study was conducted evaluating data from 240 patient charts aged from 18 to 65 years. Pain was measured by the Heft-Parker Visual Analog Scale; dental anxiety by Corah's Dental Anxiety Scale; and oral health-related quality of life by the Oral Health Impact Profile (OHIP-14). Associations were analyzed using Pearson's Chi-square test (p < 0.05). A statistically significant association was observed between pain and poorer quality of life, with impacts on psychological discomfort (p < 0.001), physical incapacity (p < 0.001) and the psychological (p < 0.001) and social (p < 0.001) domains. Anxiety influenced poorer quality of life, with impacts on the psychological discomfort (p = 0.009), physical disability (p = 0.016), psychological disability (p = 0.011) and social disadvantage (p = 0.028) domains. This study is relevant for the planning of programs and actions aimed at the oral health of patients treated in dental emergency services, prioritizing those with the greatest psychosocial impact arising from oral problems.

Radiographic quality of root canal fillings performed in a postgraduate program in endodontics

The aim of this study was to evaluate the standard quality of 1,347 root fillings performed by postgraduate students in Endodontics according to 3 radiographic quality parameters. The analyzed quality parameters included apical extension (AE), taper (TA) and homogeneity (HO), which received scores S2 (ideal standard), S1 (slight deviation) or S0 (accentuated deviation). A perfect filling (PF) received S2 for all parameters. In the absence of one or two S2 score, the fillings were deemed as satisfactory (SF) or deficient (DF), respectively. The results showed 51.7 percent, 41.5 percent and 6.8 percent of PF, SF, and DF, respectively. AE, TA, and HO presented equivalent quality parameters in root-filled canals of mandibular incisors and mandibular premolars (p>0.05). Conversely, in maxillary incisors, canines and distal root of mandibular molars, significant differences (p<0.05) were found between 2 parameters. Besides, there were significant differences (p<0.05) among the measured parameters in root-filled canals of maxillary premolars, all root canals of the maxillary molars and mesial root of the mandibular molars. AE showed the lowest frequency of S2 score for all groups. In conclusion the prevalence of perfect, satisfactory and deficient fillings varied significantly according to the root canal group. The quality parameters categorized fillings in 3 complexity degrees. AE was the most critical parameter of quality in root canal fillings.

O objetivo deste estudo foi avaliar o padrão de qualidade de 1.347 obturações de canais radiculares realizadas por estudantes de pós-graduação em endodontia, conforme 3 parâmetros radiográficos. Os parâmetros de qualidade analisados incluíram limite apical (LA), conicidade (CO) e homogeneidade (HO), os quais receberam escores E2 (padrão ideal), E1 (suave desvio) ou E0 (desvio acentuado). Obturação perfeita (OP) recebeu E2 em todos os parâmetros. Na ausência de um ou dois E2, as obturações foram consideradas satisfatórias (OS) ou deficientes (OD), respectivamente. Os resultados mostraram 51,7 por cento, 41,5 por cento e 6,8 por cento de OP, OS e OD, respectivamente. LA, CO e HO apresentaram semelhantes parâmetros de qualidade nos canais radiculares de incisivos e pré-molares inferiores (p>0,05). Em contrapartida, nas obturações de incisivos superiores, caninos e canais distais de molares inferiores, foram encontradas diferenças significativas entre 2 parâmetros (p<0,05). Além disso, houve diferença significativa (p<0,05) entre os parâmetros medidos em obturações de canais radiculares de pré-molares superiores, todos os canais radiculares de molares superiores e canais mesiais de molares inferiores. LA mostrou a menor frequência de E2 para todos os grupos. Em conclusão, a prevalência de obturações perfeitas, satisfatórias e deficientes variou significativamente em função dos grupos de canais radiculares. Os parâmetros de qualidade categorizaram as obturações em 3 graus de complexidade. LA foi o parâmetro crítico da qualidade das obturações dos canais radiculares.

Comparison of the time required for removal of intraradicular cast posts using two Brazilian ultrasound devices

The aim of this in vitro study was to compare the time required for removal of intraradicular cast posts cemented with zinc phosphate (ZF) or glass ionomer cement (GIC), using two Brazilian ultrasound devices (BUD). Seventy two human inferior premolars with single root canals were sectioned transversally at the cementoenamel junction. In each specimen, the root canal was endodontically treated, the post space was prepared to a depth of 9 mm and the canal was molded to obtain a post impression. After the casting procedures, the posts were randomly distributed into 2 groups (n = 36) according to the luting material used: G1 - ZF and G2 - GIC. The tooth and luted post set was then embedded in an acrylic resin block. The groups were then divided into 3 subgroups (n = 12) according to the ultrasound device used: A - Enac (Osada Electric, Japan), used as a control group; B - Profi II Ceramic (Dabi Atlante, Brazil) and C - Jet Sonic Satelec (Gnatus, Brazil). The posts were submitted to the vibration process with maximum power set on all surrounding surfaces. Time of application was recorded with a chronometer until complete post dislodgment, and the data were analyzed by the ANOVA test (p < 0.05). The averages required for post removal in G1 and G2 were respectively 41.42 and 92.03 seconds, with significant statistical difference (p = 0.001). No statistical difference was observed among the three ultrasound devices (p = 0.088), and the BUD presented a performance similar to that of the international gold standard device (Enac). Moreover, the type of luting agent had a greater influence on the time required for post removal than the origin of the ultrasonic unit.

Influence of luting agents on time required for cast post removal by ultrasound: an in vitro study

OBJECTIVE: This in vitro study evaluated the influence of luting agents on ultrasonic vibration time for intraradicular cast post removal. MATERIAL AND METHODS: After endodontic treatment, 30 roots of extracted human canines were embedded in resin cylinders. The post-holes were prepared at 10 mm depth and their impressions were taken using autopolymerizing acrylic resin. After casting procedures using a nickel-chromium alloy, the posts were randomly distributed into 3 groups (n=10) according to the luting material: G1- zinc phosphate (SS White) (control group), G2 - glass ionomer cement (Vidrion C; SS White), and G3- resin cement (C&B; Bisco). In G3, the adhesive procedure was performed before post cementation. After 24 h, the cement line was removed at the post/tooth interface using a fine diamond bur, and the ST-09 tip of an Enac ultrasound unit was applied at maximum power on all surfaces surrounding the posts. The application time was recorded with a chronometer until the post was completely dislodged and data were analyzed by ANOVA and Tukey's test (p<0.05). RESULTS: The roots were removed from the acrylic resin and inspected to detect cracks and/or fractures. The means for G1, G2, and G3 were 168.5, 59.5, and 285 s, respectively, with statistically significant differences among them. Two G3 posts resisted removal, one of which developed a vertical fracture line. CONCLUSIONS: Therefore, the cement type had a direct influence on the time required for ultrasonic post removal. Compared to the zinc phosphate and glass ionomer cements, the resin cement required a longer ultrasonic vibration time.

O objetivo deste estudo foi avaliar a influência da qualidade do tratamento de canal radicular (TCR), de fatores relacionados à restauração coronária (RC), lesões de cárie e parâmetros clínicos periodontais no estado periapical de dentes tratados endodonticamente. Pacientes (n=124) com TRC realizados nos Cursos de Especialização em Endodontia da Universidade Federal dos Vales do Jequitinhonha e Mucuri, no período de 2002-2005, foram reavaliados clínica e radiograficamente, entre outubro de 2009 e janeiro de 2010. Foram coletados dados contidos nos prontuários odontológicos (idade, gênero, endereço, telefone, dente tratado, estado periapical pré-operatório, tipo de tratamento, técnicas de instrumentação e obturação empregadas, radiograia final da obturação e tipo de restauração coronária)...

Tratamento não-cirúrgico de lesão periapical de origem endodôntica associada à fístula extra-oral / non-surgical treatment of periapical lesion of endodontic origin associated with extraoral fistula

É rara a ocorrência de fístula extra-oral de origem dentária. Neste relato de caso, a paciente apresentou-se com uma fístula na região do mento, queixando-se da freqüente exsudação purulenta e do marcante comprometimento estético. Diagnosticou-se necrose pulpar no dente 31 associada à radiolucidez periapical. Simultaneamente à limpeza e anti-sepsia da fístula, realizou-se o tratamento endodôntico mediante instrumentação, seguido de renovação mensal de pasta à base de hidróxido de cálcio, por três meses, com ulterior obturação do canal radicular. Não foram prescritos antibióticos. A ferida cutânea cicatrizou-se num período de dez dias. Em 20 meses de preservação não houve recidiva da fístula e, radiograficamente, ocorreu completa reparação periapical. Esteticamente, não houve necessidade da cirurgia plástica no mento.

Extraoral fistula of dental origin is a rare occurrence. In the present case report, endodontic treatment was performed in a patient presenting with a periapical radiolucent area associated with fistula at the chin region, which often exhibited purulent exudate with severe esthetic impairment. Endodontic instrumentation was performed simultaneously to cleaning and antisepsis of the fistula with saline and triclosan soap; following, a calcium hydroxide and CPMC paste was applied and changed monthly for 3 months, when the root canal was filled. No antibiotics were prescribed. The fistula healed after 10 days. After 20 months, there was complete repair of the periapical lesion. Moreover, no surgical procedures were required to improve the esthetics at the chin region.
