“…Similarly, clinical research found that smear layer removal from symptomatic teeth with pulp necrosis is associated with a higher success rate for endodontic therapy (3). From these perspectives, the primary tooth pulpectomy protocol taught and practiced at UFRGS contemplates the use of an intra-canal dressing (calcium hydroxide) between sessions and smear layer removal using 17% EDTA in cases of fistula, swelling, suppuration and pulp necrosis, with or without furcation/periapical involvement.…”

“…First, preoperative radiographs were obtained and the length of the working area was set at 1-2 mm short of the radiographic apex (3,8,9). Treatment was performed in a single visit for vital and non-infected teeth and a minimum of two appointments for teeth with abscesses, swellings or periapical and/or inter-radicular radiopacities .…”

“…Pulpectomy is a technique recommended for the treatment of irreversible pulp inflammation or necrosis caused by dental trauma or caries, and is considered a conservative option compared with tooth extraction (2). The main goal of endodontic intervention is to recover the functional aspects of the affected tooth by healing or preserving the integrity of the periapical tissue, while eliminating the microorganisms from root canals to prevent subsequent reinfection (1,3).…”

Although endodontic treatment is widely recommended for compromised dental pulp, there is no information regarding the factors associated with failures in primary teeth. The aim of this study was to evaluate the survival and factors associated with failure of pulpectomies performed in primary teeth by dental students. The sample comprised patients treated at a University Dental Service and required endodontic treatment in primary teeth. The study investigated treatment-related variables and patient factors potentially associated with treatment failure. Pulpectomy survival was analyzed by Kaplan-Meier estimator followed by log-rank test (p<0.05). The analysis included 81 pulpectomies performed in 62 children (5.6±1.5 years). The survival reached 62.9% up to 12 months follow-up. Most failures occurred in the first 3 months (p<0.001). Teeth with carious lesions at the start of treatment presented more failures than those with restorations or history of trauma (p=0.002). The survival of endodontically treated teeth restored with composite was higher than the ones filled with GIC (p=0.006). Pulpectomy performed in two or more sessions resulted in more failures (p=0.028). Patients presenting gingivitis had more failures in the endodontic treatment (p=0.022). The failures of root canal treatment in primary teeth were more prone to occur in a short time and when the treatment was performed in teeth presenting carious lesions. The use of composite instead of GIC increased the survival of pulpectomies. Repeated sessions for endodontic treatment and lack of oral hygiene habits had a negative effect on the results.

“…However, Barcelos et al (2012) showed increased success from 70% to 91% when the smear layer was removed from primary teeth during a pulpectomy. The study used a citric acid solution to remove the smear layer, performed treatment over two visits, used a camphorated paramonochlorophenol interim intracanal medicament, irrigated with 2.5% NaOCI, obturated the primary canal with zinc oxide-eugenol paste, and evaluated the outcome after twenty four months.…”

“…Although different protocols for pulpectomy in primary teeth have been described in the literature (Mortazavi & Mesbahi, 2004;Trairatvorakul & Chunlasikaiwan, 2008;Barcelos et al, 2012), they all agree that pulpectomy procedures are feasible only in teeth exhibiting minimal physiological or pathological root resorption, not exceeding 1/3 of the root length.…”

Background: The root canal length (RCL) estimates is an essential step for total endodontic therapy procedures. The aim of this study was to measure the RCL in a sample of extracted primary anterior teeth and compare the data obtained with the literature for educational and clinical purposes. Materials and methods: Seventy extracted primary anterior upper and lower teeth were selected according to the following inclusion criteria: absence of root resorption and/or internal root canal anatomy complications, and no previous root canal manipulation. The teeth were assigned to six groups: upper central incisors (UCI; n = 15), upper lateral incisors (ULI; n = 13), upper canines (UC; n = 20), lower central incisors (LCI; n = 6), lower lateral incisors (LLI; n = 3), and lower canines (LC; n = 13). RCL was measured by the direct method after insertion of a #15 K-file with a silicone stopper in the root canal until the root apex and measuring with a millimetre rule. Results: Mean RCL values (mm) obtained were UCI = 14.33 ± 1.69; ULI = 14.00 ± 1.63; UC = 16.07 ± 2.43; LCI = 15.41 ± 3.20; LLI = 15.00 ± 1.73; and LC = 16.38 ± 1.51. Conclusions: The RCL direct measurement method and the results obtained were in accordance with the literature reports and can be useful for educational purposes aiming at knowledge of dental anatomy and the clinical determination of root canal treatment viability and treatment of primary teeth, as RCL is one of the parameters for the indication/contra-indication of this therapy.

The influence of smear layer removal on primary tooth pulpectomy outcome: a 24‐month, double‐blind, randomized, and controlled clinical trial evaluation

Abstract: The pulpectomy outcome was improved by smear layer removal. The outcome for teeth with pulpal necrosis, pre-operatory symptoms, or periapical/inter-radicular radiolucency was significantly improved by removal of the smear layer.
