1. Association between agenesis and root morphology of anterior teeth
Resumo Introdução A agenesia dentária pode afetar a raiz radicular e deve ser considerada no tratamento ortodôntico. Objetivo: O objetivo deste estudo foi avaliar a associação entre agenesia dentária e a morfologia radicular dos dentes anteriores. Material e método Foram avaliadas em 102 radiografias periapicais dos dentes anteriores de 51 indiví

2. Rizogênese in vitro em brotações de Luehea divaricata Mart. & Zucc.
Resumo Luehea divaricata, conhecida popularmente como açoita-cavalo, é uma espécie florestal nativa da Mata Atlântica muito utilizada para a recuperação de áreas degradadas. Sua madeira pode ser empregada para as mais diversas finalidades, o que contribuiu para a redução de suas populações naturais e ocasionou dificuldades na obtenção de semente

3. Evidences of self planting propagules of Rhizophora mangle L.
Abstract: The authors of the 19th century had demonstrated the viviparity of the species Rhizophora mangle L. with the formation of propagules in the form of spears devoid a radicle, adapted self-planting in the soil of the mangrove or to leave floating in vertical during the high tide. With low tide the propagules self-planting or remain prostrate on the so

4. Rhizobial Inoculation, Alone or Coinoculated with Azospirillum brasilense, Promotes Growth of Wetland Rice
ABSTRACT Rhizobia and associative bacteria promote growth in rice plants (Oryza sativa L.) through a series of mechanisms, but most studies on inoculation have been performed based on inoculation with these bacteria in a separate or singular manner. The objective of this study was to assess the efficiency of single/isolated inoculation and inoculation combin

5. Prevalence and morphometric analysis of three-rooted mandibular first molars in a Brazilian subpopulation
ABSTRACT The knowledge of the internal anatomy of three-rooted mandibular molars may help clinicians to diagnose and plan the root canal treatment in order to provide adequate therapy when this variation is present. Objectives: To determine the prevalence of three-rooted mandibular molars in a Brazilian population using cone beam computed tomography (CBCT)

6. Root Distribution of Peach Rootstocks Affected by Soil Compaction and Acidity
ABSTRACT Root growth can be limited by physical and chemical conditions of the soil. Compacted and acidic soils, where there is an occurrence of exchangeable Al, constitute barriers to use of the soil by plant roots. The hypothesis of this study was that physical and chemical properties of the inter-row soil of a peach orchard influence the root distribution

7. Root filling bond strength using reciprocating file-matched single-cones with different sealers
Abstract The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using one of the following approaches: Reciproc R40 file and R

8. Root and canal symmetry in the mandibular anterior teeth of patients attending a dental clinic: CBCT study
The aims of this study were to evaluate the number of roots/root canals in the mandibular anterior teeth of a Turkish population, to assess the relationship between gender or age and the frequency of two canals in a single root, and to determine the symmetry in root/root canal numbers between contralateral sides among patients. Cone-beam computed tomography

9. Rotation axis of the maxillary molar and maximum tooth movement according to force direction
Aim: To evaluate the correlation between the maxillary molar rotation center and the direction of the maximum tooth movement according to the force direction using three-dimensional finite element analysis (3D-FEA).
Methods: Computed tomography of a human tooth was used to build a finite element model, w

10. Effect of root canal preparation, type of endodontic post and mechanical cycling on root fracture strength
Objective: To evaluate the impact of the type of root canal preparation, intraradicular post and mechanical cycling on the fracture strength of roots. Material and Methods: eighty human single rooted teeth were divided into 8 groups according to the instruments used for root canal preparation (manual or rotary instruments), the type of intraradicular post

11. Root Canal Filling: Fracture Strength of Fiber-Reinforced Composite-Restored Roots and Finite Element Analysis
O objetivo deste estudo foi avaliar o efeito da técnica de obturação na resistência à fratura de raízes e analisar, por meio de análise de elementos finitos (AEF), a expansão do cimento endodôntico em duas diferentes técnicas de obturação. Trinta dentes humanos unirradiculares foram instrumentados com limas rotatórias, com um comprimento de trab

12. Endodontic filling removal procedure: an ex vivo comparative study between two rotary techniques
In this study, we compared the ex vivo removal capacity of two endodontic rotary techniques and determined whether there was a significant quantitative difference in residual material when comparing root thirds. Forty extracted molars were used. The palatal roots were selected, and the canals were prepared using a step-back technique and filled using a later
