A bstract Aim and objective Apical extrusion of debris and cleaning efficacy in primary root canal treatment has not been well elucidated by using specialized pediatric rotary endodontic files. The purpose of this study is to compare the amount of apically extruded debris and cleaning efficacy during the preparation of primary molar root canals using Pro AF Baby Gold and Kedo-S pediatric rotary files. Materials and methods Twenty extracted primary molar teeth were assigned randomly to two groups ( n = 10 teeth for each group), injected with Indian Ink and instrumented using Kedo-S and Pro AF Baby Gold pediatric rotary files, respectively. The apically extruded debris was collected and dried in pre-weighed using Eppendorf tubes. The dry weight was calculated by subtracting the preoperative weight from the postoperative weight. The cleaning efficacy was evaluated after the diaphanization process. Statistics: Data were analyzed statistically using the independent sample t -test. Results The amount of apically extruded debris was significantly less for the Pro AF Baby rotary files group compared to the Kedo-S rotary files group ( p < 0.05). Cleaning efficacy was significantly better with Pro AF Baby Gold when compared to Kedo-S rotary files in the apical region of the tooth. Conclusion All instruments caused apically extruded debris in primary teeth. Pro AF baby Gold files can be used with less apical extrusion of debris. Cleaning efficacy was shown to be better with the Pro AF Baby Gold pediatric rotary endodontic file. How to cite this article Rathi N, Jain SA, Thosar N, et al.

Talon cusp is an unusual abnormality characterized by a cusp-like projection that occurs due to the evagination of enamel and dentin with a variable amount of pulp tissue before calcification, usually present on the cingulum area on the palatal and lingual surface of the anterior teeth. The maxillary lateral incisors are most often affected, followed by the maxillary central incisors in both primary and permanent dentition. The etiology is unknown. This developmental anomaly is rare on the facial surfaces of mandibular canines and very few cases have been reported. When it occurs on the facial surface, it usually affects the esthetics and functioning.The present case report describes an unusual case of a facial talon cusp on a permanent mandibular left canine in a 12-year-old girl. To date, only 1 such case has been reported to our knowledge and it requires careful dental and radiographic examination of the affected patient since the findings can be of clinical significance.
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.
