“…The loss of 1 marginal ridge resulted in a 46% loss in tooth rigidity, and a MOD preparation resulted in an average loss of 63% in relative cuspal rigidity. Several studies were conducted to determine the ideal materials and techniques to restore endodontically treated teeth because their long-term prognosis depends on the quality of the final restoration (39)(40)(41)(42). Usually, to restore endodontically treated teeth several resin increments are required to fill the cavity preparation because of the large volume of the restoration.…”

SummaryAim. To determine and compare the fracture resistance of endodontically treated teeth restored with a bulk fill flowable material (SDR) and a traditional resin composite. Methods. Thirty maxillary and 30 mandibular first molars were selected based on similar dimensions. After cleaning, shaping and filling of the root canals and adhesive procedures, specimens were assigned to 3 subgroups for each tooth type (n=10): Group A: control group, including intact teeth; Group B: access cavities were restored with a traditional resin composite (EsthetX; Dentsply-Italy, Rome, Italy); Group C: access cavities were restored with a bulk fill flowable composite (SDR; Dentsply-Italy), except 1.5 mm layer of the occlusal surface that was restored with the same resin composite as Group B. The specimens were subjected to compressive force in a material static-testing machine until fracture occurred, the maximum fracture load of the specimens was measured (N) and the type of fracture was recorded as favorable or unfavorable. Data were statistically analyzed with one-way analysis of variance (ANOVA) and Bonferroni tests (P<0.05). Results. No statistically significant differences were found among groups (P<0.05). Fracture resistance of endodontically treated teeth restored with a traditional resin composite and with a bulk fill flowable composite (SDR) was similar in both maxillary and mandibular molars and showed no significant decrease in fracture resistance compared to intact specimens. Conclusions. No significant difference was observed in the mechanical fracture resistance of endodontically treated molars restored with traditional resin composite restorations compared to bulk fill flowable composite restorations.

“…Some characteristics as ease and speed of placement, sealing efficacy, and high bond strength qualify the ideal restorative material to barrier (11), and the use of dentin bonding agents has been advocated to help provide a better intracoronal seal (12). Therefore the aim of this in vitro study was to evaluate the ability sealing of glass ionomer and composite resin with or without 1-mm thickness of Coltosol on the root-canal filling material.…”

Purpose: To evaluate the ability sealing of glass ionomer and composite resin with or without 1-mm thickness of Coltosol on the root-canal filling material.Methods: Root-canal treatment was completed on 50-extracted human mandibular unirradicular. The teeth were divided into six groups: G1, positive control; G2, negative control; G3, glass ionomer (Vidrion R); G4, Coltosol + Vidrion R; G5, composite resin; and, G6, Coltosol + composite resin. For G1 and G2 five teeth each were used and for the other groups, ten teeth each. The teeth were thermocycled and evaluated for microleakage using methylene blue dye. Specimens were sectioned and measurements made to the maximum point of dye penetration. The mean dye penetration (%) for each group was compared by ANOVA and Tukey's test for post-hoc comparisons (α=0.05).Results: The means and standard deviations of microleakage were: G1, 96.56 (±2.31); G2, 0.00 (±0.00); G3, 68.76 (±24.63); G4, 24.42 (±8.33); G5, 20.06 (±9.35); and, G6, 12.86 (±6.08).Conclusion: It was concluded that none of the materials were able to prevent microleakage. Composite resin alone or combined with coltosol and glass ionomer associated with coltosol resulted in less microleakage than the glass ionomer used alone.Key words: Coronal microleakage; adhesive system; composite resin; temporary fillings ResumoObjetivos: Avaliar a capacidade de selamento do ionomero de vidro e resina composta, com ou sem 1 mm de coltosol, sobre o material obturador endodôntico.Métodos: O tratamento endodôntico foi realizado em 50 dentes humanos mandibulares unirradiculares. Os dentes foram divididos em 6 grupos: G1, controle positivo; G2, controle negativo; G3, ionômero de vidro (Vidrion R); G4, Coltosol + Vidrion R; G5, resina composta; e, G6, Coltosol + resina composta. Os dentes foram submetidos a termociclagem e a avaliação da microinfiltração usando azul de metileno. Os especimes foram seccionados e a quantidade maxima de penetração de corante avaliado. As medias e desvios-padrão de penetração do corante (em %) para cada grupo foram analisadas pelo teste ANOVA e pelo teste de multiplas comparações de Tukey's (α=0.05).Resultados: As medias e desvios-padrão de midroinfiltração foram: G1: 96,56 (±2,31); G2: 0,00 (±0,00); G3: 68,76 (±24,63); G4: 24,42 (±8,33); G5: 20,06 (±9,35); and, G6: 12,86 (±6,08).Conclusão: Pode-se concluir que nenhum material obturador preveniu completamente a microinfiltração. Resina composta utilizada isoladamente ou associada ao coltosol e o ionômero de vidro associado ao coltosol apresentaram menor microinfiltração do que o ionomero de vidro utilizado sozinho.

“…In the study of Fabricius et al, Enterococci have been shown to have an ability to survive in root canals as single organisms without the support of other bacteria 28) . In most of recent bacterial leakage test, single bacterial inoculation with Enterococcus faecalis was used 25,26,29) . That is the reason why we used Enterococcus faecalis for this study.…”

The effect of MTAD as a final root canal irrigants on the coronal bacterial leakage of obturated root canalsThe purpose of this study was to evaluate the effects of MTAD, EDTA and sodium hypochlorite(NaOCl) as final irrigants on coronal leakage resistance to Enterococcus faecalis. Forty extracted human maxillary molars were used in this experiment. The teeth were randomly divided into positive control group (Group 1; n = 5), negative control group (Group 2; n = 5) and three experimental groups (n = 30). In Group 3 (n = 10), the root canals were irrigated with sodium hypochlorite. In Group 4 (n = 10) and 5 (n = 10), the root canals were irrigated with sodium hypochlorite and rinsed with EDTA and MTAD, respectively. The teeth in each group were cleaned and shaped to #40 profile with .04 taper, and obturated with gutta-percha and AH-26 root canal sealer. The coronal portion of each tooth was placed in contact with inoculum of Enterococcus faecalis in Brain Heart Infusion (BHI) culture media. Each root tip was placed in a vial containing sterile culture media. The vials were placed in anaerobic chamber and observed everyday for turbidity for 180 days. Statistical analysis was performed using Fisher's Exact Test. After 180 days, Group 3, 4, and 5 showed 7, 4 and 5 leaking samples respectively. The differences in leakage resistance were not statistically significant among Group 3, 4 and 5. [J Kor Acad Cons Dent 33(4):397-404, 2008]
