“…A study by Krishna et al comparing H files with Mtwo rotary files showed that 66.7% of children preferred H-files which was attributed to the air-rotor-like appearance of the motor which may provoke fear/anxiety. 32 The operator's comfort was more for the Mtwo file group, though not statistically significant possibly due to less fatigue and improved cutting efficacy of the rotary files. 33 …”

A bstract Background A pulpectomy is regarded as the choice modality of treatment for necrotic teeth. The use of hand files, though popular traditionally as a gold standard, may be challenging due to increased chairside time. Postoperative pain is one of the most common complications of pulpectomy and may be unpleasant for a child/pedodontist. Rotary files were found to reduce instrumentation time, reduce apical extrusion, and in turn reduce pain but there is a lack of studies in primary teeth particularly for pediatric and reciprocating file systems. The increased number of options available today makes it a dilemma for the operator to choose a suitable file system. Aim and objective The study aimed to evaluate and compare the instrumentation time, postoperative pain, and effect on child's behavior among three groups, i.e., hand K-flex files (group I), pediatric rotary files (group II), and reciprocating files (group III). Materials and methods A total of 75 primary molar teeth after meeting inclusion criteria were randomly allocated into three groups. During the procedure, step-wise instrumentation time was recorded using a stopwatch. The child's behavior pre- and postoperatively was assessed by an evaluator. The postoperative pain (up to 1 week) was assessed by a questionnaire. Results The mean age of children taken for the study was 6.03 ± 1.2 years with 46 males and 29 females. The mean biomechanical preparation time was observed to be significantly shorter in the pediatric rotary and reciprocating file groups vs hand K-flex files ( p < 0.001**). The postoperative pain after 6 hours had a mean value of 0.88 + 0.9 for the hand K-flex file group which was significantly higher than both rotary file groups ( p < 0.05*). The pre- and postoperative behavior revealed no significant difference. Conclusion The clinical performance of pediatric and reciprocating files was superior, but the choice of file system did not significantly alter behavior.

“…H-files are favored in primary teeth since they enter canals readily with minimum resistance. H-files remove hard tissue on withdrawal, thus preventing infected material from being pushed out of the apex [ 13 ]. Although hand instrumentation is considered to be the most satisfactory method for canal shaping and debridement, it can sometimes result in iatrogenic errors such as perforation and ledge formation and is generally time-consuming [ 14 ].…”

“…Higher chances of file separation occur if used in reaming action as the junction between two cones of the instrument is fragile. Therefore, H-files should be used in filing action only [ 13 ]. Various studies have concluded that it is time-consuming to prepare a thin curved canal with stainless steel files and requires the restriction of apical enlargement to relatively small sizes [ 34 ].…”

Background. Successful outcome of endodontic treatment depends on chemomechanical preparation of the tooth. However, during canal preparation, debris may extrude through the apical foramen causing postoperative complications. The aim of this study is to evaluate and compare the amount of apically extruded debris during the pulpectomy procedure in primary molar teeth using two different rotary files and hand files. Materials and Methods. Distal roots of sixty extracted primary molars were divided into three groups: group A: Prime Pedo™ pediatric rotary files, group B: DXL-Pro Pedo™ pediatric rotary files, and group C: hand files. Myers and Montgomery experimental model was used. Preweighed Eppendorf tubes were used to collect apically extruded debris. The tubes were then placed in an incubator at 70°C for 5 days. The weight of the debris attained was determined. The data were analyzed using ANOVA and post hoc Bonferroni test. Results. Hand files produced more apical debris extrusion ( P < 0.05 ). Prime Pedo™ pediatric rotary files produced the least debris ( P < 0.05 ). Conclusion. Prime Pedo™ and DXL-Pro Pedo™ pediatric rotary files extruded significantly lower amount of debris apically during pulpectomy as compared to hand files. Rotary files can be considered an alternative to hand files in pediatric endodontics.

“…Em seu estudo Krishna et al, (2019) Os autores ainda explicam que a eficacia de limpeza das limas manuais foi superior às rotatorias no terço coronal devido a coroa ser mais dura, e com a instrumentação manual é possivel pressiona-las contra a parede da dentina e, consequentimente, obter um desbridamento mais eficaz. Em contrapartida, a redução da pressão exercida pelas limas rotatorias explica a maior eficacia apresentada pela intrumentação mecanizada no terço médio (Mehlawat et al, 2019).…”

A saúde dos dentes de leite é crucial para a qualidade de vida infantil, mas a cárie é comum e pode levar a tratamentos complexos. Problemas como a colaboração das crianças e a complexidade dos canais radiculares dificultam o tratamento. Assim, a instrumentação mecânica é preferida às limas manuais, pois limpa melhor os canais, acelera o tratamento e cria canais mais uniformes e previsíveis. Este estudo se propõe a revisar as vantagens e desvantagens do uso da instrumentação mecanizada no tratamento de dentes decíduos, com base em artigos científicos de fontes respeitáveis como SciELO, MEDLINE, PubMed, Springer e Periódicos Capes. Após uma pesquisa que inicialmente encontrou 575 artigos, 12 deles foram selecionados para o estudo com base em critérios de inclusão e exclusão. Esses artigos foram publicados entre 2018 e 2022, com 2019 tendo o maior número de publicações (5), seguido por 2022 (4) e 2018 (2). Um estudo de 2020 também foi incluído, mas nenhum estudo de 2021 foi selecionado, por falta de publicações neste ano. O uso da instrumentação mecanizada para tratar dentes de leite está mostrando ser promissor, oferecendo maior eficácia, segurança e precisão em comparação com os métodos manuais tradicionais. No entanto, há uma falta de estudos clínicos nessa área, destacando a necessidade de realizar mais pesquisas.
