TOOTH AGENESIS - THE PROBLEM AND ITS SOLVING IN OUR PRACTICE, PREVALENCE AND RELATION WITH OTHER DEFORMITIES. [PDF]

open access: yesJournal of IMAB, 2015
Tooth agenesis is an orthodontic abnormality affecting the number of teeth. This leads to various types of malocclusion, disturbance in the masticatory function and poor esthetics. This survey includes 1510 orthodontic patients treated by us.

Normal pre-eruptive inclinations of maxillary canine, lateral incisor, and first premolar in children aged 6–14 years

open access: yesJournal of Orthodontic Science, 2023
BACKGROUND: Maxillary canine is the second most common tooth that gets impacted after III molars. Early pre-eruptive inclination changes of first premolar and its associative changes with canine inclination are an important factor that predicts the fate ...

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

A randomized control trial comparing buccal infiltration of 4% articaine with buccal and palatal infiltration of 2% lignocaine for the extraction of maxillary premolar teeth

open access: yesContemporary Clinical Dentistry, 2019
Introduction: The use of articaine has been claimed to obviate the need for routine palatal local anesthetic injections on account of its better diffusion through soft and hard tissues as compared to other local anesthetic agents.

Premolar Extraction Affects Mandibular Kinematics

open access: yesEuropean Journal of Dentistry, 2022
Abstract Objectives The practice of premolar extraction in orthodontics is controversial for its potential detrimental effects on the stomatognathic system. However, the ways in which premolar extraction affects mandibular function are still poorly understood.

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

Root canal morphology assessment of the maxillary first premolar using cone-beam computed tomography(CBCT) imaging in a selected Iranian population

open access: yesCaspian journal of dental research, 2021
Introduction: Considering the effect of ethnicity and race on the root canal morphology of different teeth, this study was conducted to determine the root canal anatomy of permanent maxillary first premolars using cone-beam computed tomography (CBCT) in ...

Dentin thickness of C-shaped root canal walls in mandibular premolars based on cone-beam computed tomography: a retrospective cross-sectional study [PDF]

open access: yesRestorative Dentistry & Endodontics
Objectives This study aimed to measure the dentin thickness of C-shaped canals in mandibular first and second premolars at coronal, middle, and apical root levels using cone-beam computed tomography (CBCT).
