Frequency of mesiodens in the pediatric population in North India: A radiographic study

2013

Objectives: Mesiodens are the most common supernumerary teeth, occurring in 0.15% to 2.2% of the population. The aim of the present study was to analyze the frequency and radiological features of mesiodens in the pediatric population. Material and methods: The study was based on the radiographic evaluation of 4133 pediatric patients of the age range of 4-15 years, attending the Department of Oral Medicine and Radiology during the time period between September 2008 to December 2012. In addition to the presence of a supernumerary tooth between the 2 central incisors, data regarding the number, position, shape and associated complications were also recorded. Results: The prevalence of mesioden…

Characterization and classification of different genotypes in a population of Cucumis melo based on their ability to regenerate shoots from leaf expl…

1995

Variability of the in vitro organogenic response from leaf explants of a seed population of Cueumis melo L. ev. Cantaloupe Charentais was analyzed to detect genotypic variability among individual seeds for shoot regeneration. Variation in shoot regeneration frequency among plants from different seeds was compared to that found among clonal replicas of each original plant. Clonal propagation was performed using in vitro culture of apical and axillary buds of axenic plants to avoid somaclonal variation. Results demonstrate the existence of highly significant differences among plants from the seed population. Regeneration frequency of leaf explants derived from clonally propagated sets of a si…

Incidence, severity and orthodontic treatment difficulty index of impacted canines in Saudi population

2018

Background The objective of this study was to assess the incidence, severity and orthodontic treatment difficulty of impacted maxillary canines in Saudi population. Material and methods This retrospective study included an investigation of panoramic radiographs for patients attended College of Dentistry, Jazan University, Saudi Arabia. The incidence of canine impaction and orthodontic treatment difficulty index of maxillary canine impaction was assessed based on; (1) patient age, (2) vertical position, (3) buccolingual position, (4) horizontal position, (5) incisors alignment, (6) canine space, (7) midline coincidence, (8) rotation of impacted tooth. Statistical analyses were calculated by …

Estudio volumétrico de la cresta ósea infracigomática mediante tomografía computarizada de haz cónico

2023

Introducción. El estudio anatómico en tres dimensiones de la cresta infracigomática bajo un protocolo de estudio común, previo a la colocación de dispositivos de anclaje temporal, proporciona al clínico una herramienta de pronóstico clave en la seguridad y estabilidad del tratamiento. Objetivos. El propósito de la presente tesis doctoral fue evaluar de forma transversal la cresta ósea infracigomática (IZC) mediante Tomografías Computarizadas de Haz Cónico (TCHC) en primeros y segundos molares superiores, para el estudio sistematizado y enfocado a la colocación de dispositivos de anclaje temporal en ortodoncia. Los objetivos fueron: determinar la altura total de la cresta infracigomática en …

Stafne's bone defect:a systematic review

2022

This systematic review integrated the available data published in the literature on Stafne?s bone defect (SBD), considering the clinical, imaging and histopathological results. An electronic search was undertaken in six databases. Eligibility criteria were: articles in English, Spanish, and Portuguese describing case reports or case series of SBD, reported up to September/2021. Risk of bias was assessed using the Joanna Briggs Institute tool. A total of 98 articles were retrieved, involving 465 individuals with SBD and were included for quantitative analysis. Mean age was 52.78 years (range: 11-89 years), with male predilection (n=374/80.85%). Radiographs were the most frequent imagiologica…

Histological findings of osteonecrosis spotted prior to tooth extractions. Should we consider tooth extraction still the main trigger event?

2021

Osteonecrosis of the jaw (ONJ) is an adverse drug reaction described as the progressive destruction and death of bone that affects the mandible and maxilla of patients exposed to the treatment with medications known to increase the risk of disease, in the absence of a previous radiation treatment. Tooth extraction often precedes the manifestation of ONJ; indeed, it is sometimes called trigger event and it have also been considered as risk factors for the onset of ONJ. As a consequence, some of the guidelines recommend avoiding tooth extractions in patients at risk of ONJ; however, a growing body of evidence indicates that dental/periodontal infection prior to extraction, rather than dental …

Diagnostic challenges and potential early indicators of breast periprosthetic anaplastic large cell lymphoma

2020

Abstract Rationale: Anaplastic large T-cell lymphoma (BI-ALCL) is a rare primitive lymphoma described in women with breast implant prostheses, which has been arousing interest in recent years due to its potentially high social impact. The difficult diagnosis associated with the high and increasing number of prosthetic implants worldwide has led to hypothesize an underestimation of the real impact of the disease among prosthesis-bearing women. The aim of this work is to search for specific radiological signs of disease linked to the chronic inflammatory pathogenetic mechanism. Patient concerns: This work describes a case of BI-ALCL in an American woman with no personal or family history of c…

Benign paroxysmal positional vertigo as a complication of osteotome expansion of the maxillary alveolar ridge.

2001

Benign paroxysmal positional vertigo (BPPV) is a common vestibular end organ disorder characterized by short, often recurrent episodes of vertigo that are triggered by certain head movements in the plane of the posterior semicircular canals. BPPV may be idiopathic or secondary to a number of underlying conditions such as head injury, viral labyrinthitis, stapes surgery, and chronic suppurative otitis media. 1,2 The most commonly accepted theory postulates the development of BPPV as a result of canalolithiasis, 3 heavy, inorganic particles detached from the otoconial layer by degeneration or head trauma gravitate into the posterior semicircular canal and act as a plunger on the endolymph and…
