Primary tooth pulpectomy overfilling by different placement techniques: A systematic review and meta-analysis

Abstract

Background. This study was conducted to investigate root canal overfilling with different material placement techniques in primary teeth. Methods. A systematic search was undertaken by searching PubMed/MEDLINE and Scopus for English language peer-reviewed articles published until February 2018 that reported primary tooth pulpectomy overfilling. Two reviewers independently screened and identified studies in terms of the selection criteria and independently collected the data using a specially designed data extraction form. The overfilling rate was the primary summary measure. The weighted pooled overfilling rates were estimated by random-effects meta-analysis. Results. Twenty clinical and four in vitro studies met the eligibility criteria. In the clinical studies, the pooled overfilling rate for zinc oxide-eugenol (ZOE) was 23.3% with a lentulo spiral mounted on a handpiece, 22.7% with a hand-held lentulo spiral, and 17% with a plugger. The pooled overfilling rate for calcium hydroxide-based materials was 16.7% with a lentulo spiral mounted on a handpiece, 14.7% with a hand-held lentulo spiral, 19.6% with a syringe, and 25.7% with a plugger. In the in vitro studies, neither individual overfilling rates nor two-by-two comparisons were subjected to meta-analysis because of an inadequate number of studies. Conclusion. The lowest overfilling rate in the clinical studies was related to plugger and handheld lentulo spiral techniques for ZOE and calcium hydroxide-based materials, respectively

Gestational Serum Retinol Deficiency Is Associated with Enamel Hypoplasia

“…In our study, most hypoplastic defects were located in the labial/buccal surfaces, and in incisors, the defects decreased in frequency from cervical toward incisal; however, canines and first molars followed the opposite trend corresponding to the report by Asl Aminabadi et al (2009). This could be attributed to the intensity and timing of deciduous teeth development as only the incisal part of canines and the occlusal portion of the molars are complete when the cervical portion of incisors are almost completed (Lunt and Law 1974;Peter and George 1977).…”

Efficacy of Combination of Biodentine and Simvastatin as Pulp Capping Materials in Vital Pulpotomy of Primary Molars: Randomized Clinical Trial

“…In addition, 1.5 mg of Simvastatin had superior marginal adaptation and is preferred for use as a direct pulp capping material (12) . Simvastatin, on the other hand, increased the rates of cell death at higher concentrations (12,19,21) .…”

Defects‐related early childhood caries as hints of possible maternal–fetal health issues: Evidence from medieval northern Italy

“…The hypoplastic defects may vary in form of furrows, pits, or planes of enamel thickness deficiency (Schroth et al, 2021). Hypocalcifications are expressed as opaque white patches in the translucent enamel, in form of demarcated or diffuse opacities, caused by disruption at the maturation stage (Aminabadi et al, 2009; Castro et al, 2021). Discolorations are deposits of pigments as a result of disorders during the mineralization phase (Hillson, 2014).…”

“…Insults that occurred during this interval can permanently impair the primary enamel, providing a chronological indicator of the stressful events. Therefore, defects of primary teeth are often suggestive of diseases and dysfunctions suffered by the mother and the fetus during pregnancy (Aminabadi et al, 2009; Cook & Buikstra, 1979).…”

“…Insults that occurred during this interval can permanently impair the primary enamel, providing a chronological indicator of the stressful events. Therefore, defects of primary teeth are often suggestive of diseases and dysfunctions suffered by the mother and the fetus during pregnancy (Aminabadi et al, 2009;Cook & Buikstra, 1979). DDE are considered in several clinical studies (Caufield et al, 2012;Schroth et al, 2021) to be the major predisposing factor to early childhood caries (ECC) onset, as they compromise the structural integrity of teeth (Enwonwu, 1973).…”
