BACKGROUND Dakosaurus and Plesiosuchus are characteristic genera of aquatic, large-bodied, macrophagous metriorhynchid crocodylomorphs. Recent studies show that these genera were apex predators in marine ecosystems during the latter part of the Late Jurassic, with robust skulls and strong bite forces optimized for feeding on large prey. METHODOLOGY/PRINCIPAL FINDINGS Here we present comprehen...

This study evaluated factors that affected pulpectomy (PE) success and its effect on the succedaneous tooth's eruption and enamel formation. Sixty-five of 250 patients with PEs met the selection criteria and yielded 81 zinc oxide-eugenol PEs (30 incisors, 51 molars) followed a mean time of 90.8 months. Overall PE success was 77.7% with no difference between molars and incisors (P = 0.53). Ename...

Labium is a primitive transantarctic genus which parasitizes ground-nesting halictid bees and until now has been known only from the Australian Region. Diagnostic features include its large exposed labrum (as long as clypeus) ; elongate mandible with upper tooth much shorter and smaller than lower tooth; slender 1st gastric tergite with spiracle distad of middle; and short, concealed ovipositor...

Objective: To evaluate Stage III of the Begg technique using finite element method and to locate the center of rotation (Crot) during torquing and uprighting of the central incisor. Materials and methods: The maxillary central incisor was subjected to a finite element study. Movement of the tooth along the z-axis (labiolingual) and X-axis (mesiodistal) was noted. The Crot was located by finding...

INTRODUCTION Inverted tooth impaction is a rare occurrence. Third molar impaction is the most extensively studied, and only eight cases of inverted third molars have been reported in a literature search of 40 years from 1973 to 2013. In a study, 43.4% of the premaxillary supernumeraries were inverted and 21.1% were transversely oriented, while occasional inverted central incisors have been ment...

Rabbits (Oryctolagus cuniculus) and rodents possess continuously growing teeth, and dental problems are a major health issue in these species. Knowledge of tooth growth characteristics is required to adequately treat dental problems and advise owners concerning diets. Most research was performed using bur marks and measuring eruption and wear manually. However, this method cannot be applied to ...

INTRODUCTION Esthetics is one of the common issues because of which patients consult dental orthodontic treatment. Two ways of tooth bleaching are available these days, which includes in-office bleach and home bleach. Various bleaching protocols are available these days for treating the tooth surfaces. Hence, we planned the present study for investigating the impact of various intracoronal blea...

. Herein we report the first record of Purussaurus Barbosa-Rodrigues for Neogene Argentina. This genus is recorded in Miocene beds different localities Colombia, Venezuela, Brazil, and Perú, includes at least three species with total body lengths ranging from 8 to 13 m. The material reported here a partially preserved tooth (MAS-PV 386) found locality Toma Vieja (Paraná, Entre Ríos Province, Ar...

Introducción: Tooth development may be interrupted when the pulp becomes necrotic because of caries, trauma, or anatomical alterations such as dens evaginatus.Objective: To determine depth cure and hardness an injected bulk-fill resin (Sonic Fill™) compared with a flowable (Revolution™) in teeth incomplete apex formation.Material Methods: Forty recently extracted uniradicular were assigned for ...

PURPOSE This study was performed to obtain a quantitative evaluation of the cortical and cancellous bone graft harvestable from the mental and canine regions, and to evaluate the cortical vestibular thickness. MATERIALS AND METHODS This study collected cone-beam computed tomographic (CBCT) images of 100 Italian patients. The limits of the mental region were established: 5 mm in front of the m...
