O tratamento endodôntico permite a permanência de dentes na cavidade oral. No entanto, procedimentos inadequados podem ocasionar o escurecimento dentário, acometendo a estética do sorriso e levando à baixa autoestima do paciente. O objetivo do presente estudo é relatar um caso clínico de retratamento endodôntico não cirúrgico, seguido de clareamento endógeno em dentes anteriores escurecidos para reabilitar os elementos tanto funcional quanto esteticamente. Paciente do gênero feminino, 25 anos, compareceu à clínica de Odontologia de uma Universidade relatando insatisfação com seu sorriso. A queixa principal se fundamentava na baixa autoestima em decorrência do escurecimento dos incisivos central e lateral superiores esquerdos após tratamento endodôntico realizado oito meses antes. Ambos os dentes estavam assintomáticos, mas clinicamente exibiam exposição de guta-percha sem selamento coronário. Radiograficamente o elemento 21 apresentava sobre-extensão de material obturador. A conduta adotada foi a reintervenção endodôntica dos elementos 21 e 22 com sepultamento do fragmento de guta-percha extrarradicular e posterior clareamento dentário interno, além de restaurações em ambos os elementos. O retratamento endodôntico não cirúrgico e o clareamento endógeno foram eficazes para a resolução do caso, pois possibilitaram a manutenção dos elementos dentários em função na cavidade oral e o restabelecimento da estética do sorriso, garantindo satisfação da paciente.Descritores: Endodontia; Retratamento; Clareamento Dental.ReferênciasTorabinejad M, White SN.

Background: To investigate the efficiency of Hedstrom (H; Dentsply Maillefer) file, Protaper Universal Retreatment system (PTUR; Dentsply Maillefer), Mani NRT-GPR files (Mani, Japan) and WaveOne (WO; Dentsply Maillefer) Reciprocating files in removing Gutta Percha (GP) and sealer from root canals. Methods: Sixty canals with less than 10° curvature from extracted human maxillary incisors were used. Root canal reinstrumentation was performed with H, PTUR, Mani NRT-GPR and WO files. Amount of residual root filling material (Gutta-percha and or sealer) were measured by using stereomicroscope. Data of GP or sealer remnants were statistically analyzed using one-way analysis of variance and Tukey test. Results: There were no significant differences among 4 groups in terms of residual root filling material in the apical third (p > 0.05). H-file group showed highest amount of root residual root filling as compared to groups. Conclusions: Reciprocating file system proved to be more efficient in removing the root canal fillings material than other retreatment file systems. H file group showed highest amount of root canal filling material. Bangladesh Med Res Counc Bull 2019; 45: 54-61

The objective of root canal obturation is to achieve a fluid-tight seal. Recently, GuttaFlow bioseal (GB), a root canal sealer composed of polydimethylsiloxane, gutta-percha particles, and bioactive glass ceramics, has been developed, to enhance the sealing ability of root canal filling material. The objective of this study was to assess the sealing ability of GB using a subnanoliter-scaled fluid-flow measuring device and to compare with that of AH Plus (AH). The fluid flow in root canal-filled teeth using either gutta-percha cone (GP) with AH (GAR; n = 10) or GP with GB (GBR; n = 10) and in GP inserted in AH blocks (GA; n = 10) or GP inserted in GB blocks (GB; n = 10) was measured. In addition, fluid flow in sealer blocks of AH (A; n = 10) and GB (B; n = 10), which served as negative controls, was measured. Root canal-filled teeth using GP without any sealer (GR) acted as positive controls (n = 10). The leakage was obtained by calculating the volume of moved water by time (s), after stabilization of the fluid flow was achieved. Statistical analysis was performed using the Kruskal–Wallis test and Mann–Whitney U-test with Bonferroni correction. A p value less than 0.00238 (0.05/21) was considered significantly different. The mean leakages (nL/s) in the groups are as follows: GAR, 0.0958 ± 0.0543; GBR, 0.0223 ± 0.0246; GA, 0.0644 ± 0.0803; GB, 0.0267 ± 0.0182; A, 0.0055 ± 0.0057; B, 0.0052 ± 0.005; and GR, 0.2892 ± 0.3018. The mean leakage in the GBR group was lower than that in the GAR group (p = 0.001), while the mean leakages in the GA and GB groups were not significantly different. GuttaFlow bioseal can be useful in single-cone obturation technique.
