“…According to the present results, the null hypotheses for root canal volume and surface need to be rejected, since root canal preparation with both rotary file systems resulted in significantly greater increase in root canal volume and surface in both primary teeth and permanent teeth. These results confirm two recent studies evaluating the shaping effectiveness of different rotary files vs hand files in primary teeth . Presumably, the greater conicity of the rotary instruments compared with conventional hand files contributed to more dentine removal in the coronal region, resulting in greater post‐preparation root canal volume and surface area.…”

“…5 Rotary files were first evaluated in primary teeth by Barr et al, 6 who concluded that root canal preparation was faster with rotary files than with manual files, and produced uniform and predictable canal morphologies. Although few other studies have evaluated the performance of rotary file systems in the primary dentition, [7][8][9][10][11][12][13] their outcomes are still limited to provide an exact conclusion.…”

Background Root canals of primary teeth are commonly prepared with endodontic files that are originally manufactured for permanent teeth. Aim This micro‐computed tomography (micro‐CT) study evaluated and compared the changes in root canal morphology after preparation with different conventional and rotary files in primary teeth and young permanent teeth. Design Seventy‐two extracted primary and permanent molars were selected and randomly assigned to three subgroups according to the file systems used (n = 12/each). After pre‐scanning of teeth with micro‐CT, root canals were prepared with One Shape and Revo‐S rotary systems and conventional endodontic files. After rescanning procedure, changes in canal volume, surface area, uninstrumented surface area, and apical transportation were evaluated. Mann‐Whitney U test, Kruskal‐Wallis test, and Conover's multiple comparison test were used for statistical analysis (P = .05). Results Instrumentation with rotary files resulted in significantly greater volume and surface area of root canals and less uninstrumented areas (P < .001) than with manual files (P < .001). Primary molars showed significantly less apical transportation than permanent teeth (P < .001). Conclusions Preparation of canals with rotary files could be a viable alternative to conventional files in primary teeth. Regardless of the file system used, uninstrumented areas still exist in both primary teeth and permanent teeth.

“…Our results support the concept that endodontic treatment in primary dentition should follow the same biological principles applicable to permanent teeth, and manual or rotary instrumentation techniques are safe procedures for primary molars without significant root resorption [27]. Advantages of the LSTR concept [5] such as less chair time, single-visit treatment and providing an option for poor-prognosis molars, might be considered in public service dentistry, but its cost-effectiveness deserves further investigation.…”

Objective: To investigate the two-year survival rate of primary molars treated with non-instrumentation endodontic treatment with mixed antibiotic paste containing chloramphenicol, tetracycline, zinc oxide and eugenol (CTZ pulpotomy), and compare it to the conventional root canal treatment with calcium hydroxide paste. Material and Methods: Thirty-six children, mean age 6.2 years old (standard deviation, SD=1.5), presenting at least one primary molar with irreversible pulpitis or necrotic pulp, were included in this prospective clinical study. Teeth were assigned to CTZ pulpotomy (Group I) or calcium hydroxide pulpectomy (Group II) and assessed clinically and radiographically for up to 26 months. Data were analyzed using descriptive statistics, Chi-square test, Kaplan-Meier survival analysis and Log-rank test. Results: Fifty-three primary molars were treated in Group I (n=37) or Group II (n=16). Children were followed up for 1 to 26 months (mean=12.0; SD=7.1). Treatment failure rates were 73.0% in Group I and 31.3% in Group II. Overall, mean survival time was 15.2 months (95% confidence interval, CI 12.6-17.9); Group I (mean 13.2; 95% CI 10.2-16.3) had a lower survival rate than Group II (mean 18.9; 95% CI 14.5-23.2) (p=0.02). Necrotic pulp treatments had significantly lower survival rates (p=0.01) than pulpitis treatments. Conclusion: Non-instrumentation endodontic treatment of primary molars with CTZ paste resulted in a low survival rate in a two-year follow-up; its radiographic ineffectiveness discourages its use instead of conventional root canal endodontic treatment.

Evaluation of the efficacy of rotary vs. hand files in root canal preparation of primary teeth in vitro using CBCT

Abstract: Rotary files prepared more conical canals in primary teeth than manual instruments. Reduced preparation time with rotary files enhances patient cooperation especially in young children.
