Endodontic treatment in primary teeth can be challenging and time consuming, especially during canal preparation, which is considered one of the most important steps in root canal therapy. The conventional instrumentation technique for primary teeth remains the "gold-standard" over hand instrumentation, which makes procedures much more time consuming and adversely affects both clinicians and patients. Recently nickel-titanium (Ni-Ti) rotary files have been developed for use in pediatric endodontics. Using rotary instruments for primary tooth pulpectomies is cost effective and results in fills that are consistently uniform and predictable. This article reviews the use of nickel-titanium rotary files as root canal instrumentation in primary teeth. The pulpectomy technique is described here according to different authors and the advantages and disadvantages of using rotary files are discussed.
Trauma to front tooth is one of the disturbing conditions for children and parents. The treatment strategies used to treat the immature young dentition are important for the long-term prognosis of teeth and should aim at preserving pulp vitality to secure tooth maturation and root development. This article describes a case of trauma to upper front tooth with open apex. The patient was treated with vital pulp therapy with mineral trioxide aggregate to induce apexogenesis.
Background and Objectives:
Conventionally, stainless steel crown (SSC) is the preferred material for the restoration of pulpotomized primary molars. However, in situations where stainless steel cannot be used necessity for other restorative material arises.
Aim:
The aim of this study is to assess the microleakage of several coronal seal materials in pulpotomized primary molars–
in vitro
.
Methodology:
Seventy-five primary molars were prepared with proximo-occlusal cavities. Restoration was done with Zinc oxide eugenol cement, SSC, composite resin, resin-modified glass-ionomer cement (GIC), and amalgam. Microleakage was assessed using dye penetration technique with stereomicroscope and scanning electron microscope.
Statistical Analysis and Results:
The Kruskal–Wallis and Mann–Whitney tests were used to statistically analyze the results.
Conclusion:
With regard to this present study composite resin and resin-modified GIC offers a good alternative for SSC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
