Root surface areas in long-term survivors of childhood cancer
Oral Oncology, 2003Treatment regimes for childhood cancer are known to affect the root development in the long-term survivors (LTS) but the available the data is subjective in nature with very few quantitative data in the literature. This study aimed to quantify the root surface area (RSA) of mandibular teeth in LTS compared with controls and relate this to the treatment

The role of cell walls and pectins in cation exchange and surface area of plant roots
Journal of Plant Physiology, 2017We aimed to assess role of cell walls in formation of cation exchange capacity, surface charge, surface acidity, specific surface, water adsorption energy and surface charge density of plant roots, and to find the input of the cell wall pectins to the above properties.

A Computer‐Aided Image Analysis System for Area Measurement of Tooth Root Surfaces
Journal of Periodontology, 1990The characteristics of a computer‐aided Image Analysis System (IAS) to conduct linear and area measurements on tooth root surfaces were investigated. The borders of the features to be measured were extracted from a digitized video image by histogrambased thresholding and binarization. The lengths and square areas were expressed in the number of pixels.

Modulation of dental root surface area through GLMs. Clinical applications
AIP Conference Proceedings, 2015The amount of periodontal attachment around the tooth is an important prognostic factor for dental treatment planning.The aim of this study is to estimate the quantity of remaining of attachment area of a tooth affected with periodontitis.Ageneralized linear model was fitted to data from mandibular pre-molar teeth scanned a high-resolution micro-CT ...

Root biomass and surface area in three successional tropical forests
Canadian Journal of Forest Research, 1982Total root biomass and surface area of fine roots (<5 mm diameter) were determined to a depth of 85 cm in 1-, 8-, and 70-year-old tropical forests on the same soil type (Typic Dystrandept) at Turrialba, Costa Rica. Root biomass and root area index (RAI) increased with age: biomass = 219, 1291, and 1555 g/m2, and RAI = 1.34, 4.66, and 5.28 in the 1-,

Surface Area Measurement of Corn Root Systems1
Agronomy Journal, 1982AbstractThe density or amount of roots per unit of soil is important when evaluating the use of soil water and nutrients by plants. The most commonly used measurement of roots is mass, but more recently root length measurements have been reported. We believe root surface area is of critical importance in assessing water and nutrient uptake.

Calculation of Simplified Single‐Root Surface Area From Simulated X‐Ray Projection
Journal of Periodontology, 2002Background: The prognosis of a tooth affected by periodontitis might depend on the amount of bone remaining around the root surface. The surface area of a single tooth root relates to a simulated x‐ray projection.Methods: The aim of the study was to determine root surface area from radiographs. Two methods were used.

Measurement of the root surface area in rat molars through three-dimensional modeling
Archives of Oral BiologyRats are used as animal models for basic and applied research related to orthodontic tooth movement (OTM). The magnitude of mechanical force in OTM rat models mainly depends on the supporting capability of the periodontal ligament (PDL), which is highly associated with the root surface area (RSA).
