AIM The purpose of this study was to evaluate the effectiveness of Haas RPE anchored on deciduous teeth in the early mixed dentition, for inducing the spontaneous correction of permanent incisor's crossbite, without compliance, without post bite-plane and no involvement of the permanent teeth. MATERIALS AND METHODS The sample group comprised 50 consecutive patients (mean age 8y 5m, SD 2y 1m),...

OBJECTIVES The purpose of this study was to determine the Young's modulus and the hardness of deciduous and permanent teeth following wear challenges using different dental materials. MATERIALS AND METHODS Wear challenges were performed against four dental materials: A resin-based fissure sealant (Fluoroshield(®)), a glass ionomer based fissure sealant (Vitremer(®)), and two microhybrid compo...

Background and Objective: Stem cell therapy is a new treatment option for osteoarthritis. A various applications of stem cell therapy have been used for cartilage regeneration in arthritis patient. The objective of this study was to examine therapeutic effects of puppy deciduous teeth stem cells for the treatment of osteoarthritis using a rabbit model. Methodology: In this study, rabbits were s...

Study Design: Prospective randomized controlled trial Aim: The aim of the present study was to clinically and radiologically evaluate two root canal filling materials in infected deciduous teeth over a period of 6 months. Background data: Pulp treatment in deciduous teeth is challenging due to the complex anatomy of the root canal system. The limitations in biomechanical preparation and root ca...

Dental caries is the most common chronic childhood disease. Deep caries and dental trauma are the two main etiologic factors responsible for pulp involvement. Better knowledge of the morphology of the root canals of deciduous teeth can improve the outcome of pulp treatment. In this study, 90 deciduous molar teeth (27 first mandibular molars, 27 first maxillary molars, 22 second mandibular molar...

BACKGROUND Nonsense mutations in FAM83H are a recently described underlying cause of autosomal dominant (AD) hypocalcified amelogenesis imperfecta (AI). OBJECTIVE This study aims to report a novel c.1374C>A p.Y458X nonsense mutation and describe the associated ultrastructural phenotype of deciduous teeth. METHODS A family of European origin from the Iberian Peninsula with AD-inherited AI wa...

Tree species in the boreal forest cycle between periods of active growth and dormancy alter their photosynthetic processes in response to changing environmental conditions. For deciduous species, these changes are readily visible, while evergreen species have subtler foliar changes during seasonal transitions. In this study, we used remotely sensed optical indices to observe seasonal changes in...

AIM This study evaluated the prevalence of the chewing side preference (CSP) in the deciduous, mixed and permanent dentitions. MATERIALS AND METHODS Three-hundred subjects were divided in three groups (n = 100): Group 1 - children with deciduous dentition; group 2-children with mixed dentition; group 3 - subjects with permanent dentition. The CSP was determined using a direct method (visual o...

The deciduous habit of northern temperate trees and shrubs provides one of the most obvious examples of convergent evolution, but how did it evolve? Hypotheses based on the fossil record posit that deciduousness evolved first in response to drought or darkness and preadapted certain lineages as cold climates spread. An alternative is that evergreens first established in freezing environments an...

The diversity of litter ant assemblages in evergreen, deciduous and Shola evergreen (Shola) forest vegetation types of the Wayanad region of the Western Ghats was assessed employing conventional and taxonomic diversity indices. Non-dependence on quantitative data and the ability to relate the phylogenetic structure of assemblages with ecological conditions of the habitat, and to ascertain prior...
