Aim of the study to determine whether and to what extent the reattachment of fractured incisor tooth fragments is weakening the teeth and which adhesive material and technique offers the strongest bond to the tooth structure. Materials and methods 48 extracted mandibular incisors divided into 4 groups were used. After fracturing the incisal third of each tooth, the fragments were reattached wit...

A Brazilian girl aged 14 years and 9 months presented with a chief complaint of protrusive teeth. She had a convex facial profile, extreme overjet, deep bite, lack of passive lip seal, acute nasolabial angle, and retrognathic mandible. Intraorally, she showed maxillary diastemas, slight mandibular incisor crowding, a small maxillary arch, 13-mm overjet, and 4-mm overbite. After the diagnosis of...

Objective: The objective of this study was to investigate the relationship between age, gender and clinical crown length using a longitudinal study design. Method: Four hundred and fifty-six sets of study models initially obtained for a large prospective longitudinal cohort study of orthodontic needs were examined. Each set of models corresponded to subjects at three different ages: 11–12, 14–1...

introduction multiple dentigerous cysts are rare and mostly associated with syndromes. case presentation the present case report is unique, as the dentigerous cysts enclosed the lateral incisor, canine, first and second premolars of the mandible and were accompanied by a complex odontoma, instead of first mandibular molar. conclusions multiple unilateral nosyndromic dentigerous cysts with compl...

BACKGROUND Considerable variations in the development stage among patients of the same chronological age have led to introduce the concept of the developmental age based on the maturation of different organs such as cervical vertebrae or teeth. OBJECTIVES The purpose of this study was to investigate the correlation between the stages of tooth calcification and the cervical vertebral maturatio...

Purpose: The aim of this study was to investigate and evaluate the changes of incisor inclination and arch width in the surgical-orthodontic treatment to correct a Class III malocclusion resulting from skeletal mandibular prognathism. Materials and methods: The skeletal mandibular prognathism subjects consisted of 25 males and 20 females (mean age:22.8±4.2years). A lateral cephalogram was taken...

Dens in dente, also known as dens invaginatus and dilated compound odontoma, is a malformation that can occur on primary, permanent, or supernumerary teeth that is characterized by a deep invagination of the surface of a crown or root covered with enamel. This abnormality in tooth morphology generally affect the maxillary lateral incisors but several cases of multiple dens invaginatus have been...

From a selection of four kinds of post and core systems, including a fiber post and composite resin core, the purpose of this study was to determine the most effective system for the restoration of endodontically treated teeth with 0 mm of coronal tooth structure. For experimental abutment teeth, typical human maxillary central incisor teeth were modeled using bovine mandibular incisor teeth. B...

The objective of this study was to present a classification of the root development stage of female rat molar teeth and to evaluate the variation in the lactate dehydrogenase (LDH) activity and electrophoretic isoenzyme profile according to the stage of root development of the molar teeth. We also studied the LDH activity and isoenzymes of the pulp of incisor teeth. The stage of development of ...
