Marsupialization of a large dentigerous cyst in the mandible with orthodontic extrusion of three impacted teeth. A case report

2017

The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar. The DC was treated successfully by marsupialization and extrusion of the impacted teeth. In conclusion, the combination of …

Optimal application of compressive palatal stents following mesiodens removal in pediatric patients:a Randomized Controlled Trial

2021

Background There is no scientific evidence supporting the choice of a palatal stent in patients who underwent removal of an impacted supernumerary tooth. We aimed to investigate the effects of palatal stents in patients who underwent supernumerary tooth removal through a palatal approach and to suggest the optimal stent thickness and material. Material and Methods We recruited 144 patients who underwent extraction of a supernumerary tooth between the maxillary anterior teeth. Subjects were assigned to a control group (CG) or one of four compressive palatal stent groups (CPSGs) classified by the thickness and material of the thermoplastic acrylic stent used. Palatal gingival swelling and obj…

Minimally invasive prosthetic procedures in the rehabilitation of a bulimic patient affected by dental erosion

2015

The population affected by dental erosion due to bulimia is generally very young. This population group has a high aesthetic requirement; the dentition in these patients is severely damaged, especially in the anterior maxillary quadrant. In terms of treatment, it is still controversial whether an adhesive rehabilitation is preferable to a longer-lasting but more aggressive conventional treatment, such as full-crown coverage of the majority of teeth. This case report describes the prosthetic rehabilitation of a young female patient previously affected by bulimia nervosa and presenting erosion of the maxillary teeth. The prosthetic rehabilitation was performed through indirect adhesive restor…

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…
