The effect of three different primary teeth rotary instrument systems on the amount of apically extruded debris in pulpectomy of primary teeth.

Purpose: The objective of this study is to evaluate the amount of apically extruded debris and working time during root canal treatment with three different primary teeth rotary instrument systems.

Materials And Methods: A total of 80 extracted primary second molar teeth were randomly divided into four groups (n=20) stratified by the instruments used: AF Baby Rotary, Easyinsmile Baby Rotary, Endoart Pedo Gold, and hand files. The apical extrusion of debris was collected then dried in Eppendorf tubes that were pre-weighed with 10-4 precision micro-balance.

Determination of the effect of two different methods of dental anesthesia on pain level in pediatric patients: A cross-over, randomized trial.

Background: In dentistry, needles are the most feared and anxiety-causing tool, making anesthetic injection a worrying practice for patients.

Aim: To evaluate the effect of intraosseous anesthesia (IOA) and needle-free dental anesthesia (NFA) on pain levels in systemically healthy 8-10-year-old patients.

Patients And Methods: Twenty patients aged 8-10 years were included in this cross-over study.

Evaluation of the effect of pediatric drugs and an oral rinse on primary teeth discoloration.

Background: Changes in the color of the teeth are a common dental finding associated with clinical and esthetic problems. Especially, the discoloration of primary teeth can cause parental concern and have a negative effect on social interactions between preschool children.

Objectives: The aim of the study was to evaluate the effect of pediatric drugs and an oral rinse on the discoloration of primary teeth.

Is zirconium or stainless steel the most suitable crown material for less dentin stress in endodontically treated teeth?

Background: Stainless steel crowns (SSCs), which have been used frequently in the treatment of first permanent molars in children until now, has become less applicable due to its poor aesthetic appearance. Zirconia crowns (ZCs) have become more popular due to their aesthetic advantage. However, stress transmission of ZCs to dental tissues under occlusal forces in endodontically treated teeth has not been described.

Dental age estimation with two different methods in paediatric patients with hypothyroidism.

Objective: This case-control study aimed to evaluate dental age estimation in children with hypothyroidism using two different methods in order to contribute to the literature about the most accurate method.

Design: In the study, panoramic radiographs of 80 patients with hypothyroidism aged 5-13 years and 80 randomly selected age and sex-matched healthy patients were examined retrospectively. The Cameriere's and the Nolla's methods were used for the dental age estimation.
