A common dilemma in adult orthodontic treatment is deciding how best to treat missing posterior teeth. One treatment option is to orthodontically close the space. But closure can be difficult, especially if the open space is in the maxillary posterior area, because tooth movement through the maxillary sinus is limited. The increased difficulty of moving teeth in the maxillary sinus is similar t...

Implant treatment is an attractive substitute to the traditional prosthetic appliances. However, diabetes mellitus has long been considered a relative contraindication to dental implant therapy. In this case report, we present the results of an immediate implant placement in fresh extraction sockets of mandibular anterior teeth and the implantation of the edentulous posterior mandibular regions...

The purpose of this ex vivo study was to determine the accuracy template-based guided endodontics for access cavity preparation and root canal detection in posterior teeth. First, three maxillary four mandibular models were constructed using 67 premolars molars, with a total number 135 main canals. Cone beam computed tomography (CBCT) three-dimensional 3D surface scans each model performed matc...

The most common congenital and developmental anomaly in teeth is the missing of one or more of them. Congenitally missing teeth (CMT) or teeth agenesis mentions failure of tooth formation due to disturbances during the early stages of tooth germ development. There are several definitive treatment options for these patients including fixed, removable or implant-supported prostheses. Economic lim...

OBJECTIVE The aim of this study was to investigate the three-dimensional (3D) position of the center of resistance of 4 mandibular anterior teeth, 6 mandibular anterior teeth, and the complete mandibular dentition by using 3D finite-element analysis. METHODS Finite-element models included the complete mandibular dentition, periodontal ligament, and alveolar bone. The crowns of teeth in each g...

BACKGROUND Tooth extraction is associated with dimensional changes in the alveolar ridge. The aim was to examine the effect of single versus contiguous teeth extractions on the alveolar ridge remodeling. MATERIAL AND METHODS Five female beagle dogs were randomly divided into three groups on the basis of location (anterior or posterior) and number of teeth extracted - exctraction socket classi...

The Anterior Dental Loading Hypothesis states that the unique Neanderthal facial and dental anatomy was an adaptive response to the regular application of heavy forces resulting from both the masticatory and cultural use of the anterior teeth. Heavy anterior tooth wear frequently observed in Neanderthal specimens is cited as a main source of evidence for heavy forces being applied to these teet...

OBJECTIVE To determine the association of high occlusal force (HOF) with the signs of occlusal trauma and periodontal conditions in periodontitis patients, and elaborate the relevant clinical implications. METHODS Periodontal parameters and signs of occlusal trauma were recorded for 807 teeth in 30 subjects with untreated chronic periodontitis. The T-scan II occlusal analysis system determine...

The purpose of this study was to associate oral hygiene frequency and presence of visible biofilm in the primary dentition. The sample consisted of 90 children, aged up to 4 years old, outpatients of the University Hospital of the Rio de Janeiro State University. The examinations were carried out in a dental office by a single trained examiner who was aided by an assistant. The parents answered...

The purpose of the study was to assess the prevalence and pattern of dental caries in the deciduous dentition among 5 year old children. The area of study was Rawalpindi and Islamabad and the study population consisted of 504 school children of both sexes (263 males and 241 females). A simple random sampling method was used to select the schools. Dental caries was assessed by the Dentition stat...
