“…21 To decrease the amount of leakage and bacterial contaminations, medicaments are added in the pulp canal space. 22 Except for subgroups containing Cavit with chlorhexidine (CHX) and specimens in subgroups CHX with IRM, all other samples showed a comparatively higher leakage in group without intrapulp medicaments as compared with other groups (Tables 4 to 7). We also observed that subgroups containing calcium hydroxide (CaOH) with Coltosol and CaOH with Cavit showed the presence of minimal microleakage up to 3 weeks' time.…”

Introduction: Coronal leakage is one of the constant concerns in routine dental practice. It is one of the factors responsible for the failure of root canal therapy. Permanent restorations should be given as soon as possible after the completion of root canal therapy. If unavoidable, provisional restoration should be given in such a way that it maximally reduced the leakage of micro organisms and fluids from the external environment into the canal space. Hence, we evaluated the effect of saliva on the coronal leakage of temporary restorations. Materials and methods:Biomechanical preparation of the root canals of 204 fresh mandibular first premolar teeth was done using endodontic files with intermittent irrigation of sodium hypochlorite solution and ethylenediaminetetraacetic acid. Alternate irrigation with normal saline was done periodi cally. After preparation, drying of the canals was done using paper points followed by sealing of the apical foramen. For the assessment of the microleakage, Siqueira et al apparatus and method was used. All the specimens were divided into four groups based on the provisional restorative material used. All the groups were further divided into three subgroups based on the presence and absence of intracanal medicaments. Verissimo et al's criteria were used to check the turbidity at 1, 2, 3, and 4week interval respectively. All the results were analyzed by

“…A outra abordagem consiste na eliminação das bactérias remanescentes ou em torná-las inofensivas por sepultamento após uma obturação hermética tridimensional, para privar a nutrição dos micro-organismos e o espaço necessário para sobreviver e se multiplicar 15,16 . Contudo, nem o tratamento em sessão única nem o de sessão múltipla podem eliminar completamente as colônias microbianas 17 . Em relação à redução de endotoxinas, o tratamento em sessão única mostrou-se menos eficaz do que em sessões múltiplas 18 .…”

IntroduçãoO tratamento endodôntico é realizado, na maioria dos dentes, com taxas de sucesso variáveis 1,2 . Grande parte dos dentistas realiza esse tratamento em sessões múltiplas 3 . No entanto, nas últimas dé-cadas, mais de 70% das escolas, em diversas áreas geográficas, e pesquisadores defendem o tratamento em sessão única 4 . É pouco contestada a possibilidade de realização do tratamento do canal radicular em sessão úni-ca nos casos diagnosticados como pulpite irreversí-vel 4,5 . No entanto, em casos de necrose pulpar com ou sem periodontite apical, a literatura é controversa 6 . A periodontite apical é causada por bactérias no interior dos canais, e o seu tratamento deve ser feito com a remoção da causa. O preparo mecânico associado a uma irrigação pode promover culturas bacterianas negativas em 40% a 60% dos dentes tratados 7,8 . Além disso, o uso da medicação intracanal foi sugerido para potencializar a obtenção de culturas negativas 9 . Historicamente, inúmeros tratamentos e medicações entre sessões foram utilizados para a terapia de dentes infeccionados, mas ao longo dos anos o número de sessões foi reduzido. Para os casos de sessões múltiplas, um curativo de demora à base de hidróxido de cálcio tem sido proposto como padrão--ouro 4 . Assim, acreditava-se que a taxa de reparação do tratamento em sessões múltiplas devia ser mais elevado do que o tratamento em sessão única 9 .

Objective: The aim of this study was to evaluate the ability of a new irrigant solution QMix, in the microbial reduction of Enterococcus faecalis from infected root canals in comparison with sodium hypochlorite 5.25%. Materials and Methods: 40 extracted mandibular premolars with single root canal have been prepared with rotary protaper instrument until F3 and irrigated with saline, and then they were sterilized by moist heat sterilization at temperatures 121°C for 20 min. After that, they were injected with 50 μ of Enterococcus faecalis suspension in the density of 10 8 , and then the root canals were incubated in a temperature of 37°C for 7 days in aerobic and anaerobic conditions. Next, the root canals were divided into two groups. Group 1 is irrigated with sodium hypochlorite 5.25%, Group 2 is irrigated with QMix. Each specimen was irrigated for 40 s, and the solution was left inside the canal for 30 s. The bacterial swabs were taken by sterilized paper points in two stages; the fi rst one was after the end of incubation period, and the second one was immediately after the irrigation. Student's t-test and Chi-square test were used to compare bacterial reduction Log(10) values between the groups. Results: Sodium hypochlorite was more eff ective than QMix (P < 0.05). There were no signifi cant diff erences in the bacterial reduction Log(10) percent between anaerobically and aerobically incubated roots in sodium hypochlorite 5.25% solution group (P > 0.05), whereas bacterial reduction Log(10) percent in anaerobically incubated roots were lower than those of aerobically incubated roots in Qmix solution group (P < 0.05). Furthermore, the percentage of full cleansing in the sodium hypochlorite group was greater than those of Qmix solution group (P < 0.05). However, the percentage of full cleansing in the QMix group was zero. Conclusions: Sodium hypochlorite 5.25%, had clear ability on the microbial reduction of E. faecalis in comparison with the new irrigant QMix.
