Artigo JOE MAIO 2010- Penetration of Sodium Hypochlorite into Dentin

Penetration of Sodium Hypochlorite into Dentin

Volume 36, Issue 5, Pages 793-796 (May 2010)
Abstract


Introduction
Sodium hypochlorite (NaOCl) is the most commonly used root canal irrigant. The aim of this study was to evaluate the effect of concentration, time of exposure, and temperature on the penetration of NaOCl into dentinal tubules.

Methods
Thirty extracted human permanent maxillary anterior teeth with single canals were instrumented by using ProTaper rotary files. The teeth were then sectioned perpendicular to the long axis. The crowns and apical thirds of all the teeth were removed. The remaining roots were processed into 4-mm-long blocks and stained overnight in crystal violet. One hundred eight stained blocks were treated by 1%, 2%, 4%, and 6% NaOCl for 2, 5, and 20 minutes at 20°C, 37°C, and 45°C, respectively. The depth of penetration of NaOCl was determined by bleaching of the stain and measured by light microscopy at magnifications of 20× and 40×. Statistical comparisons were made by using one-way analysis of variance, and Dunnett T3 tests were made for multiple comparisons.

Results
The shortest penetration (77 μm) was measured after incubation with 1% NaOCl for 2 minutes at room temperature. The highest penetration (300 μm) was obtained with 6% NaOCl for 20 minutes at 45°C. After the initial penetration during the first 2 minutes, the depth of penetration doubled during the next 18 minutes of exposure. Temperature had a modest effect within each group on the depth of penetration and in most cases was not statistically significant (P > .05). Depth of penetration increased with increasing hypochlorite concentration, but the differences were small. Within each time group, depth of penetration with 1% NaOCl was about 50%–80% of the values with the 6% solution.


Conclusions
Temperature, time, and concentration all contribute to the penetration of sodium hypochlorite into dentinal tubules.

Key Words: Concentration, dentin, penetration, sodium hypochlorite, temperature, time

Selamento de Perfuração - Prof. Flavia Abe

Paciente foi encaminhada para remoção de núcleo e retratamento do dente 21. Não apresentava sinais e/ou sintomas. A reclamação principal foi a estética da coroa. Após exame radiográfico a surpresa:  a presença de uma perfuração...

Relatório de Tratamento:

• Remoção do pino: desgaste do núcleo em resina e técnica com vibração ultrassônica;
• Retratamento: ProTaper, complementação com lima manual #45, cimento AHPlus.
• Vedação da perfuração com MTA branco, revestimento com resina flow.
• Cimentação de pino de fibra de vidro com RelyX e confecção de coroa provisória com resina fotopolimerizável.

Identifying and Reducing Risks for Potential Fractures in Endodontically Treated Teeth

Weirong Tang, DDS, Younong Wu, DDS, MSc, PhD, Roger J. Smales, BDS, MDS(Hons), DDSc

Abstract

Introduction
Although long-term functional survival rates can be high for initial endodontically treated permanent teeth, they are generally more susceptible to fracture than teeth with vital pulps. Tooth extraction is often the consequence of an unfavorable prognosis after coronal and root fractures, but their occurrence in endodontically treated teeth might be reduced by identifying the risks for fracture associated with various operative procedures.

Methods
This article presents an overview of the risk factors for potential tooth fractures in endodontically treated teeth on the basis of literature retrieved from PubMed and selected journal searches.

Results
Postendodontic tooth fractures might occur because of the loss of tooth structure and induced stresses caused by endodontic and restorative procedures such as access cavity preparation, instrumentation and irrigation of the root canal, obturation of the instrumented root canal, post-space preparation, post selection, and coronal restoration and from inappropriate selection of tooth abutments for prostheses.

Conclusions
Potential tooth fractures might be reduced by practitioners being aware during dental treatments of controllable and noncontrollable risks.

Key Words: Endodontic treatment, risk factors, tooth fractures

Retratamento Endodôntico do Dente 25

Abstract JOE Abril - Micro-computed Tomographic Comparison of Nickel-Titanium Rotary versus Traditional Instruments in C-Shaped Root Canal System

Journal of Endodontics

Introduction

The purpose of this study was to assess the efficacy of instrumentation of C-shaped canals with ProTaper rotary system and traditional instruments by using micro–computed tomography (micro-CT).

Methods

Twenty-four mandibular molars with C-shaped canals were selected in pairs and sorted equally into 2 groups, which were assigned for instrumentation by ProTaper rotary system (ProTaper group) or by K-files and Gates-Glidden burs (Hand Instrument group). Three-dimensional images were constructed by micro-CT. The volume of dentin removed, uninstrumented canal area, time taken for instrumentation, and iatrogenic error of instrumentation were investigated.

Results

Hand Instrument group showed greater amount of volumetric dentin removal and left less uninstrumented canal area than ProTaper group (P < .01). The time needed for instrumentation was shorter for ProTaper group than for Hand Instrument group (P < .05). No instrument breakage occurred in both groups, but more conspicuous procedural errors were detected in Hand Instrument group than for ProTaper group.

Conclusions

It was concluded that ProTaper rotary system maintained the canal curvature with speediness and few procedural errors, whereas traditional instrumentation can clean more canal surface.
