CT evaluation of apical canal transportation associated with stainless steel hand files, oscillatory technique and ProTaper rotary system
This study used computed tomography (CT) to compare apical canal transportation in mesiobuccal canals of maxillary molars prepared with different techniques. Sixty teeth were assigned to 3 groups (n=20), according to the technique used for root canal instrumentation: hand instrumentation with K-Flex...

| description | This study used computed tomography (CT) to compare apical canal transportation in mesiobuccal canals of maxillary molars prepared with different techniques. Sixty teeth were assigned to 3 groups (n=20), according to the technique used for root canal instrumentation: hand instrumentation with K-Flexofiles, K-Flexofiles activated by an oscillatory system and ProTaper NiTi rotary system. Pre and post-instrumentation CT images were obtained 3 mm short of the apical foramen and were superimposed to compare canal transportation. Data were analyzed statistically by ANOVA and Tukey's test using the SPSS software (α=0.05). In the buccal direction, the manual technique produced significantly less canal transportation than the oscillatory technique (p0.05). In the distal and distopalatal directions, the oscillatory technique produced more canal transportation (p |

Este estudo utilizou a tomografia computadorizada (TC) para comparar o transporte do canal radicular nos canais mésio-vestibulares de molares superiores preparados por diferentes técnicas. Sessenta molares superiores foram divididos em 3 grupos (n=20) de acordo com a técnica utilizada para o preparo do canal radicular: instrumentação manual com limas K-Flexofile, limas K-Flexofile acopladas a um sistema oscilatório e sistema rotatório ProTaper. Imagens de TC pré e pós-instrumentação foram obtidas 3 mm aquém do forame apical e superpostas para comparar o transporte do canal. Os dados foram analisados estatisticamente pela Análise de Variância (ANOVA) e Teste de Tukey utilizando o software SPSS (α=0,05). Na direção vestibular, a técnica manual produziu significantemente menos transporte do canal radicular do que a técnica oscilatória (p<0,05) e ambas foram similares a técnica rotatória (p>0,05). Nas direções distal e disto-palatina, a técnica oscilatória produziu mais transporte do canal radicular (p<0,05). Na direção mésio-palatina, a técnica oscilatória produziu mais transporte do canal radicular do que a técnica manual (p<0,05), sendo que ambas foram similares à técnica rotatória (p>0,05). Em conclusão, todas as técnicas produziram transporte do canal radicular e a técnica oscilatória produziu os maiores desgastes de dentina na direção interna da curvatura.]]></description><identifier>ISSN: 0103-6440</identifier><identifier>EISSN: 0103-6440</identifier><identifier>DOI: 10.1590/S0103-64402011000400005</identifier><language>eng</language><ispartof>Brazilian dental journal, 2011, Vol.22 (4), p.288-293</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c2605-c487a564f68014141cd12c0dc078780d8c5dca823fe09cdf7534e26fb87697993</citedby><cites>FETCH-LOGICAL-c2605-c487a564f68014141cd12c0dc078780d8c5dca823fe09cdf7534e26fb87697993</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,4010,27900,27901,27902</link.rule.ids></links><search><creatorcontrib>Hartmann, Mateus Silveira Martins</creatorcontrib><creatorcontrib>Fontanella, Vânia Regina Camargo</creatorcontrib><creatorcontrib>Vanni, José Roberto</creatorcontrib><creatorcontrib>Fornari, Volmir João</creatorcontrib><creatorcontrib>Barletta, Fernando Branco</creatorcontrib><title>CT evaluation of apical canal transportation associated with stainless steel hand files, oscillatory technique and ProTaper rotary system</title><title>Brazilian dental journal</title><description><![CDATA[This study used computed tomography (CT) to compare apical canal transportation in mesiobuccal canals of maxillary molars prepared with different techniques.
