Comparative evaluation of platelet-rich plasma + β-tricalcium phosphate and platelet-rich fibrin + β-tricalcium phosphate for healing periapical lesions, using cone beam computed tomography - an study.

Background: Platelet concentrates are currently being researched for their potential to enhance bone formation.

Aim: The aim of this study is to quantitatively evaluate and compare bone regeneration in periapical lesions using a combination of platelet-rich plasma (PRP) + β-tricalcium phosphate (β-TCP) and platelet-rich fibrin (PRF) + β-TCP.

Methods: Ten subjects with periapical lesions measuring 10-20 mm in relation to maxillary incisors indicated for periapical surgery were selected.

Comparative evaluation of canal cleanliness at apical third using Self-Adjusting File and Wave One File with different irrigants: an scanning electron microscopic study.

Aim: To evaluate the cleaning ability of two single-file rotary systems- Self-Adjusting File (SAF) and Wave one (WO) systems in removing the smear layer using sodium hypochlorite (NaOCl) + ethylene diamine tetraacetic acid (EDTA) and NaOCl + Qmix as irrigants at apical one-third of the root canal.

Methods: Forty extracted human mandibular premolars were selected and working length was determined. The canal was manually instrumented up to a number 25 size K-file.

Comparative Evaluation of Osteogenic Potential of Conventional Glass-ionomer Cement with Chitosan-modified Glass-ionomer and Bioactive Glass-modified Glass-ionomer Cement An Study.

Aim: The aim of this study was to compare the osteogenic potential of conventional glass-ionomer cement (GIC) with chitosan-modified GIC (CH-GIC) and bioactive glass-modified GIC (BAG-GIC) as a function of time in varying proportions.

Materials And Methods: CH-GIC was prepared by adding 10 v/v% (Group II) and 50 v/v% (Group III) CH to the commercial liquid of GIC. BAG-GIC was prepared by the addition of 10 wt% (Group IV) and 30 wt% (Group V) of BAG to the GIC powder.

Comparative Evaluation of Cleaning Efficacy of Self-adjusting File and WaveOne File: An Scanning Electron Microscopic Study.

Aim: This study aims to compare the cleaning efficacy of root canal walls using two rotary single file systems: self-adjusting file (SAF) and WaveOne (WO).

Materials And Methods: Forty extracted human premolars with similar range of canal curvature were selected, decoronated, working length determined and roots were divided into two groups of 20 samples each: Group I - SAF and Group II - WO. All root canals were irrigated with 3% sodium hypochlorite (NaOCl) and 17% ethylenediaminetetraacetic acid (EDTA).

Five root canals in peg lateral incisor with dens invaginatus: A case report with new nomenclature for the five canals.

This case report describes endodontic treatment completed in a peg-shaped maxillary lateral incisor, with single root and five root canals of which, one is due to dens invaginatus. Cone beam computed tomogram scanning confirmed the unique morphology of the tooth. New nomenclature for the five canals is proposed.
