Evaluation of the Effect of the Loading Time on the Microtensile Bond Strength of Various Restorative Materials Bonded to Silver Diamine Fluoride-Treated Demineralized Dentin.

The aim of this study was to evaluate the effect of immediate versus delayed loading times on the microtensile bond strength (μTBS) of restorative materials, including resin-based composite (RBC), resin-modified glass ionomer cement (RMGIC) and glass ionomer cement (GIC), that were bonded to silver diamine fluoride (SDF)-treated demineralized dentin. Ninety caries-free extracted premolar teeth were assigned to three groups ( = 30) loaded with RBC, RMGIC and GIC restorative materials. Each group was further divided into three subgroups ( = 10): subgroup A (control specimens), immediate loading of the restorative material on sound dentin; subgroup B, demineralized dentin, SDF treatment and immediate loading of the restorative material; and subgroup C, demineralized dentin, SDF treatment and restorative material loading a week later.

Cone Beam Computed Tomography Evaluation of Inverted Mesiodentes.

A mesiodens is the most common type of supernumerary teeth. The purpose of this report is to present a rare occurrence of non-syndromic impacted inverted mesiodentes in an 8.5-year-old boy who presented with a chief complaint of delayed eruption of his permanent maxillary left central incisor.

Combined orthodontic and periodontic treatment in a child with Papillon Lefèvre syndrome.

A 9-year-old girl with Papillon-Lefèvre syndrome (PLS) was treated orthodontically 24 months after the start of mechanical and antibiotic therapy in adjunct with periodontal treatment every 6 weeks. After achieving stable periodontal conditions, orthodontic treatment was commenced to correct the teeth position, facial profile, and maxillary protraction. Following the combination therapy and a failure to detect Actinobacillus actinomycetemcomitans from any site in the oral cavity, orthodontic treatment with a fixed appliance was performed aside from creating space for eruption of permanent teeth.

Aspects of mandibular morphology, with specific reference to the antegonial notch and the curve of Spee.

The purpose of this investigation was to determine whether particular metrical traits of the mandibular antegonial notches are associated with specific mandibular growth patterns, and also with the mean depth of the curve of Spee. Thirty pre-treatment lateral cephalometric radiographs belonging to a randomly selected group of patients treated in the orthodontic clinic at the SUNY at Buffalo were digitized. The surface areas of the mandibular antegonial notches, as well as some sagittal facial dimensions were measured on each radiograph.

The morphology of the mandibular antegonial notches and facial symmetry.

Thirty randomly selected pre-treatment postero-anterior cranial radiographs of adolescent patients attending the orthodontic department, School of Dental Medicine, State University of New York at Buffalo comprised the sample in this study. The aims of this study were (1) to compare the depths of the right, and the left, mandibular antegonial notches, and (2) to determine whether the morphology of the antegonial notches bears a statistical relationship to some other transverse metrical characters of the face. The frontal cranial radiographs of thirty patients were digitized to determine the linear, and surface area, measurements of the right, and the left, antegonial notches as well as some transverse dimensions of the faces.
