Novel Digital Technique to Quantify the Area and Volume of Cement Remaining and Enamel Removed after Fixed Multibracket Appliance Therapy Debonding: …

2020

The aim of this study was to construct a novel, repeatable, reproducible, and accurate measurement protocol for the area and volume of the remaining cement after removal of fixed multibracket appliances, the area and volume of remaining cement after cement removal, the area and volume of enamel removed after cement removal, and the volume of cement used to adhere fixed multibracket appliances. A total of 30 brackets were cemented and removed with over 30 extracted teeth embedded into three experimental models of epoxy resin. The models were scanned before and after bracket placement, bracket debonding, and polishing the remaining cement. The brackets were submitted to micro-computed tomogra…

La influencia del peso y la talla en la erupción de la dentición temporal

2017

Objetivos: investigar la cronología y la secuencia de erupción de la dentición temporal y su relación con el peso y la talla en un grupo de niños y niñas de entre 0 y 3 años tanto al nacer como en la exploración. Analizar si existen diferencias significativas en la edad de erupción entre dientes contra laterales y entre dientes antagonistas para ambos sexos. Metodología: La muestra recogida fue constituida por 489 niños de raza caucásica, de los cuales 236 eran niños (48.3%) y 253 eran niñas (51.7%), asignados a dos centros de salud, seleccionados al azar. Todos los niños eran nacidos a término y tenían una edad comprendida entre 3 meses y 36 meses de edad. Ninguno de ellos presentaba alter…

Possibilities of Dental Age Assessment in Permanent Teeth: A Review

2012

The developmental stages of the first and second dentition, combined with abrasive wear of the dental hard tissue can be used for age determination in many mammal species and in humans. Concerning dental age determination, one has to distinguish between invasive techniques, which are mainly applied in dead individuals, and non-invasive methods suitable for living individuals. In contrast to in adults, where only few parameters are available for orientation, age determination in children and adolescents is in general fairly easy, and is facilitated by stereotypical biological growth patterns. In the present article, different methods for dental age determination are introduced, with a specia…

No. of bitstreams: 0 Previous issue date: 2008-01-01 Odontogenic anomalies can occur as a result of conjoining or twinning defects. These include fusion, gemination and concrescence. This article presents two case reports of double teeth. In the first case reported, a 4-year-old white boy presented primar…

Regional odontodysplasia of the deciduous and permanent teeth associated with eruption disorders: A case report

2008

WOS: 000259667500007 PubMed: 18758400 Regional odontodysplasia (RO) is an unusual, non-hereditary anomaly of the dental hard tissues with characteristic clinical, radiographic and histological findings. Clinically, RO affects the primary and permanent dentition in the maxilla and mandible or both jaws. Radiographically, there is a lack of contrast between the enamel dentin, both of which are less radiopaque than unaffected counterparts. Additionally, enamel and dentin layers are thin, giving the teeth a "ghost-like" appearance. Histologically, areas of hypocalcified enamel are visible and enamel prisms appear irregular in direction. Coronal dentin is fibrous, consisting of clefts and a redu…

CONSORT compliance in randomized surgical trials assessing the analgesic and anti-inflammatory effectiveness of preoperative drug management of patie…

2022

Investigate methodological quality of clinical trials in mandibular third molar surgery and its compliance with the consort statement. An electronic search was performed in five journal websites, chose the five scientific journals with the greatest impact factor in oral and maxillofacial surgery according to the SCImago Journal Rank. The compliance of studies with the CONSORT statement was assessed. Also, the risk of bias of each study was evaluated. Twenty-nine studies were included. The average CONSORT compliance score was 25.50 (79.68%). Most studies were performed in the Americas (n = 14, 48.3%) and Asia (n = 10, 34.5%). Parallel-group (n=15, 51.7%) and split-mouth RCTs (n=11, 38%) were…
