background and aims. predicting the teeth eruption time is a valuable tool in pediatric dentistry since it can affects scheduling dental and orthodontic treatments. this study investigated the relationship between the eruption time of first primary and permanent teeth and the variation in the eruption time considering socioeconomic status (ses) in a 9-year population- based cohort study. materi...

objectives: this study sought to compare the push-out bond strength of two bulk-fill and one conventional composite to intracanal dentin in primary anterior teeth. materials and methods: this in vitro, experimental study was conducted on 39 primary anterior teeth, which were randomly divided into three groups. after cleaning and shaping, the root canals were filled with metapex in such a way th...

[1] In this paper, we use growing season Normalized Difference Vegetation Index (NDVI) as an indicator of plant growth to quantify the relationships between vegetation production and intra-annual precipitation patterns for three major temperate biomes in China: grassland, deciduous broadleaf forest, and deciduous coniferous forest. With increased precipitation, NDVI of grassland and deciduous b...

OBJECTIVE To determine an optimal treatment strategy for carious deciduous teeth. SETTING Manchester Dental Hospital. DESIGN Decision analysis. METHOD The likelihoods of each of the sequelae of caries in deciduous teeth were determined from the literature. The utility of the outcomes from non-treatment and treatment was then measured in 100 parents of children with caries, using a visual ...

The processes that govern diverse tropical plant communities have rarely been studied in life forms other than trees. Structurally dependent vascular epiphytes, a major part of tropical biodiversity, grow in a three-dimensional matrix defined by their hosts, but trees differ in their architecture, bark structure/chemistry and leaf phenology. We hypothesized that the resulting seasonal differenc...

statement of problem: nowadays, evaluation of the development of occlusion in deciduous teeth for creating corrective occlusion in permanent teeth is one of the most important objectives of pediatric dentistry. in other countries, a vast number of researches have been accomplished on the details of occlusion in deciduous teeth. but, unfortunately, there is still no accurate information about th...

Weibull, H. 2000. Bryophytes on boulders diversity, habitat preferences and conservation aspects. Doctor’s dissertation. ISSN 1401-6230, ISBN 91-576-5893-5 The influence of different overstorey tree species on the floristic composition of bryophytes growing on boulders was studied in two deciduous forests. Covering tree species and amount of litter were the factors explaining most of the variat...

BACKGROUND AND AIMS Plant relative growth rate (RGR) depends on biomass allocation to leaves (leaf mass fraction, LMF), efficient construction of leaf surface area (specific leaf area, SLA) and biomass growth per unit leaf area (net assimilation rate, NAR). Functional groups of species may differ in any of these traits, potentially resulting in (1) differences in mean RGR of groups, and (2) dif...

o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...

Papillon-Lefévre syndrome (PLS) is characterized by severe periodontal disease extending to destruction of the alveolar bone surrounding deciduous teeth and palmoplantar hyperkeratosis of the skin. Increased susceptibility to infection has been reported among individuals with the cathepsin C (CTSC) gene mutation. This article reports a 7-year-old Japanese girl who presented with deciduous tooth...
