PURPOSE The aim of this study was to use clinical, radiographic, and histologic examinations to compare the relative success of gray mineral trioxide aggregate (MTA), white MTA, and formocresol as pulp dressings in pulpotomized primary teeth. METHODS Twenty-four children, each with at least 3 primary molars requiring pulpotomy, were selected for this study's clinical and radiographic portion....

BACKGROUND The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CB...

This review article encompasses the literature pertaining to changes in dental pulp subsequent forces exerted secondary orthodontic treatment. The was conducted at College of Dentistry, Qassim University, Saudi Arabia, from October 2022 February 2023. A search on PubMed, Embase, Cochrane Library and Google Scholar for articles 2000 Keywords MeSH terms used were ‘orthodontic forces’, ‘pulp chang...

Eucalyptus bleached kraft pulp production, an important sector of the Brazilian national economy, is responsible for generating large volume, high pollutant load effluents, containing a considerable fraction of recalcitrant organic matter. The objectives of this study were to quantify the biological activity of the effluent from a eucalyptus bleached kraft pulp mill, characterize the nature of ...

Antioxidants play role in increasing the resistance of human body, including from virus attacks and weather changes. are found fruit influenced by secondary metabolites formed fruit. Along with level ripeness, will affect composition metabolites, thus affecting antioxidant activity. This study aims to determine yield ripeness Nypa high The old nipa pulp is higher than young pulp, 15.26% 9.82% r...

CD8 T cells are critical for the clearance of intracellular pathogens. Upon infection, naive CD8 T cells differentiate into effector cells that target and eliminate infected cells. Following clearance of the pathogen, most effector cells die, although a small fraction survives to establish a memory population. Subsequent exposure to the same pathogen induces a rapid response of memory T cells a...

background and objectives: colocynthin is the major active secondary metabolite of colocynth, citrullus colocynthis (l.) schrad, which has been used in traditional and ethno medicine of many countries.  it could be considered as an active marker for quality control of colocynth and its herbal products. analysis and standardization of colocynth and its herbal preparations are a critical issue fo...

Residual lignin carbohydrate complexes (RLCC) were isolated enzymatically from spruce and pine pulp. The RLCCs contained 4.9–9.4% carbohydrates, with an enrichment of galactose and arabinose compared to the original pulp samples. The main carbohydrate units present in all studied RLCCs were 4-substituted xylose, 4-, 3and 3,6-substituted galactose, 4-substituted glucose and 4 and 4,6-substituted...

Many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. This study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (E-BMG) in rabbit. E-BMG was prepared from tibia and femur of 4 Deutsche-Poland rabbits with average ages of 4-6 months. The prepared E-BMG was implanted in right incisor teeth pulps of...

Background The fast growth and good wood properties of Eucalyptus tree species and hybrids make them excellent renewable sources of fiber for pulp and paper production, and woody biomass for bioenergy production. Our research is aimed at understanding the genetic regulation of wood formation in eucalypts, with a focus on transcriptomes, regulatory sequences and gene families involved in seconda...
