The clinical success of different root canal treatments in primary molars

Abstract

<p><strong>Objectives:</strong> To examine the success rate of root canal treatment in primary molars with the use two different root canal instrumentation ways, irrigation solutions and root canal sealers.</p> <p><strong>Materials and Methods:</strong> Root canal treatment was applied to 120 second primary molars of 69 children between 5-8 years old. The teeth were divided in 8 groups randomly according to instrumentation ways [conventional stainless-steel hand files / Nickel-titanium (Ni-Ti) rotary files], irrigation solutions [0.5% sodium hypochlorite (NaOCl) and 0.9% saline solution combination / 0.4% chlorhehexidine (CHX)] and root canal sealers [Zinc oxide eugenol cement (ZOE) and Apexit Plus (AP)]. All teeth were restored with stainless steel crowns. The teeth were followed 12 months both clinically and radiographically. All data was analyzed statistically by χ<sup>2 </sup>and Wilcoxon test.</p> <p><strong>Results:</strong> Statistical significance were found according to “age” and “root canal sealers” factors on success rate of root canal treatment (p<0.05). No statistical significance were found according to gender, jaw, tooth type, root canal instrumentation ways and irrigation solutions on success rate of root canal treatment (p>0.05). The clinically and radiographically success rate of ZOE and AP were 98.3% and 68.3%, respectively.<strong></strong></p> <p><strong>Conclusions:</strong> Root canal treatment is a successful treatment in primary molars. Ni-Ti rotary files and CHX can be a good alternative for root canal treatment in primary molars. The most effective factor to obtain clinical success of root canal treatment is properties of using root canal sealer.</p&gt

A systematic review and meta‐analysis of randomized clinical trials comparing rotary canal instrumentation techniques with manual instrumentation techniques in primary teeth

“… The following authors were contacted for missing data or additional data: Guler et al (), Vieyra & Enriquez (), Govindaraju et al (), Mokhtari et al (), Gomes et al (). Two of the authors replied: Vieyra & Enriquez () and Mokhtari et al (); however, the data provided was insufficient and could not be pooled for quantitative synthesis. …”

“…Only one study (Subramaniam et al ) compared the cleaning effectiveness (microbial reduction) of both techniques, while no studies evaluated the behaviour of children during root canal treatment in primary teeth with either of the techniques. Five authors (Guler et al , Gomes et al , Vieyra & Enriquez , Mokhtari et al , Govindaraju et al ,) were contacted by email to obtain the missing data or additional data, but only two authors (Vieyra & Enriquez , Mokhtari et al ) responded with the data. However, the data could not be pooled for quantitative analysis.…”

“…1. After searching the six electronic databases and removal of duplicates, 2471 articles were screened for titles and abstracts, providing a total of 18 studies for full-text reading, which gave 12 articles (Ochoa-Romero et al 2011, Guler et al 2013, Subramaniam et al 2013, Makarem et al 2014, Gomes et al 2014, Topc ßuo glu et al 2017, Mokhtari et al 2017, Govindaraju et al 2017bJeevanandan & Govindaraju 2018, Morankar et al 2018, Nair et al 2018 for qualitative synthesis. Furthermore, two articles (Vieyra & Enriquez 2014, Elheeny et al 2015 were manually added from the hand search of google scholar or reference list of the included articles to give a total of 14 articles.…”

“…Assessment of clinical and radiographic success during the follow-up period was undertaken in four trials (Guler et al 2013, Vieyra & Enriquez 2014, Elheeny et al 2015, Morankar et al 2018 (Table 2). The follow-up period of two trials was 24 months (Vieyra & Enriquez 2014, Morankar et al 2018, whereas two trials (Guler et al 2013, Elheeny et al 2015 were pursued for 12 months postoperatively.…”

Root Canal Morphology of Mandibular Primary Molars: A Micro-CT Study

“…It was clearly known that fundamentally the main philosophy of a root canal treatment is filling all the spaces from which pulp removal was done in the root canal following shaping and cleaning procedures. [1][2][3] From this point of view, it is necessary to have an idea about all the internal morphological diversity in the root canal system where the pulp is likely to occupy space. 1 Root canal treatment consists of access cavity preparation and determination of working length, followed by chemo-mechanical preparation and obturation of root canal system in both dentitions.…”
