Comparative analysis of rotary versus manual instrumentation in paediatric pulpectomy procedures: A systematic review and meta-analysis.

The use of rotary file in permanent teeth is well-documented, but there is limited scientific evidence for its effectiveness in primary teeth. A meta-analysis was conducted to compare rotary and manual tools in primary tooth pulpectomy procedures. Ten databases were searched from 2000 to 2024 to find relevant literature.

Comparing the EdgeFile X3, GenEndo, HeroGold, and ProTaper Gold Rotary Instruments Regarding the Effect of Different Concentrations and Temperature of NaOCl on Cyclic Fatigue Resistance.

Aim: This research was carried out with the objective of comparison between GenEndo, Protaper Gold, Hero Gold and EdgeFile X3 regarding the effect of different concentrations of NaOCl.

Materials And Methods: About 720 study specimens were included in the study. They were divided into four groups.

Comparing Expansion of Maxillary Antrum between Periapical Surgery and Extraction of Permanent Maxillary First Molar in Pediatric Patients Using CBCT.

Aim: To compare the expansion of maxillary antrum between periapical surgery and extraction of permanent maxillary first molar in pediatric patients using cone-beam computed tomography (CBCT).

Materials And Methods: In this study, 136 participants in the age-group of 11-18 years were included. The participants were divided into two groups.

Cure lies in nature: medicinal plants and endophytic fungi in curbing cancer.

Success of targeted cancer treatment modalities has generated an ambience of plausible cure for cancer. However, cancer remains to be the major cause of mortality across the globe. The emergence of chemoresistance, relapse after treatment and associated adverse effects has posed challenges to the present therapeutic regimes.

Tear film surface quality with rigid and soft contact lenses.

Objectives: The aim of this study was to measure tear film surface quality (TFSQ) using dynamic high-speed videokeratoscopy during short-term (8 hrs) use of rigid and soft contact lenses.

Methods: A group of 14 subjects wore 3 different types of contact lenses on 3 different nonconsecutive days (order randomized) in 1 eye only. The subjects were screened to exclude those with dry eye.

Corneal changes following short-term rigid contact lens wear.

Purpose: The aim of this cross-over study was to investigate the changes in corneal thickness, anterior and posterior corneal topography, corneal refractive power and ocular wavefront aberrations, following the short term use of rigid contact lenses.

Method: Fourteen participants wore 4 different types of contact lenses (RGP lenses of 9.5mm and 10.

Regional changes in corneal thickness and shape with soft contact lenses.

Purpose: To investigate the influence of soft contact lenses on regional variations in corneal thickness and shape while taking account of natural diurnal variations in these corneal parameters.

Methods: Twelve young, healthy subjects wore four different types of soft contact lenses on four different days. The lenses were of two different materials (silicone hydrogel or hydrogel), designs (spherical or toric), and powers (3.
