OBJECTIVE To determine the timing and sequence of eruption of primary teeth in children with complete bilateral cleft lip and palate. MATERIAL AND METHODS This cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies of the University of São Paulo, Bauru, SP, Brazil, with a sample of 395 children (128 girls and 267 boys) aged 0 to 48 months, with comple...

in this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers.part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. the teeth were imbedded in autopolimerize acrylic resin. cross section was prefor...

Background and purpose: Accurate instance segmentation of teeth in panoramic dental X-rays is a challenging task due to variations tooth morphology overlapping regions. In this study, we propose new algorithm, for instance, the different X-rays. Methods: An model was trained using architecture Mask Region-based Convolutional Neural Network (Mask-RCNN). The data training, validation, testing wer...

To evaluate the influence of fluoride varnish (FV) therapies or resin infiltration (RI) to maintain structural integrity Molar Incisor Hypomineralization (MIH) -affected teeth. Fifty-one children aged 6–12 years with at least one incisor and first permanent molar yellow/brown MIH opacities were included. Patients randomly allocated into three groups: FV – Fluoride Varnish (Duraphat); FV+etch (D...

Objective: The objective of this report was to present a case of apexification in traumatized teeth treated with two different therapies for immature teeth. Methods: An 11-year-old male patient was referred to the Dental Trauma Service of the College of Dentistry — Piracicaba (UNICAMP), with enamel dentin fracture in the maxillary central incisors associated with subluxation caused by a bicycle...

OBJECTIVES To present 17 natal/neonatal teeth in 15 patients and describe their clinical characteristics, associated disorders, complications and treatment. METHODS A retrospective study of neonates who visited the Department of Pedodontics and Preventive Dentistry, College of Dental Sciences, Davangere, India, between 2003 and 2006 was carried out. It was a study of clinical data, such as th...

Cone beam computed tomography (CBCT) can be used for determining the height and width of alveolar bone surrounding implant site which are important factors in planning. This study was done to evaluate compare maxillary anterior teeth based on CBCT images from Nepalese population. retrospective included patients who had scan between January 2019 December 2020. Sagittal section views perpendicula...

Permanent central incisor impaction is very rare, and causes of include adjacent supernumerary teeth, odontoma, trauma. Surgical repositioning a treatment option for teeth with ectopic eruption pathways. In this case report, an inverted developing maxillary was surgically repositioned at the initial stage root development. Three dimensional (3D) virtual images were acquired using computed tomog...

Selection of anterior teeth depends mainly on Leon William theory that hypothesizes the presence of harmony between the face and inverted central incisor forms. If this theory is approved mathematically then the central incisor form and width could be predicted and calculated with acceptable precision in clinical practice. The purpose of this study was to predict the tooth form and mesiodistal ...
