P roper angulation of the airpolisher handpiece and use of high-velocity evacuation significantly minimize the generation and the liberation of the aerosol particles into the dental environment. 1S16 As can been seen in Figures 1 through 3. the handpiece nozzle should be held 3-4 mm from the tooth surface, The handpiece nozzle should be kept at a 60 0 angle toward the facial and lingual surface...

BACKGROUND Researchers have conducted extensive studies regarding dentoalveolar factors that affect anterior dental esthetics; however, there is no consensus regarding laypeople's perspectives on these factors. METHODS The authors conducted a systematic search of electronic databases (MEDLINE, PubMed, Embase, Cochrane Library and Web of Science) until May 2010. They identified and selected ar...

Background: The third molar is different in many ways from all the other teeth. The aim of this study was to examine how often the third lower molars are chosen as abutment tooth. Methods: A total of 228 OPG was analyzed. The number of lower third molars (M3s) present per person as well as on the right or the left side of the mandible and their relationships, for both males and females were exa...

Background: Radiography is an inseparable part of dentistry, one which cephalometric techniques. Impacted tooth a con-dition the that cannot erupt completely; whereas malocclusion mismatch between two jaws. Objective: To de-termine prevalence maxillary third molars with skeletal at Hasanuddin University Hospital and Ladokgi Ma-kassar Hospital. Methods: This descriptive observational research us...

BACKGROUND During orthodontic tooth movement friction occurs at the bracket wire interface. Out of the total force applied to the tooth movement, some of it is dissipated as friction, and the remainder is transferred to the supporting structures of the tooth to mediate tooth movement. However many factors affect friction, and method of arch wire ligation being an important contributing factor. ...

A longitudinal complicated crown-root fracture of an unerupted permanent incisor following trauma to primary teeth is reported. The development of the affected permanent tooth was not disturbed during a follow-up period of six years. Traumatic injuries to primary teeth can be transmitted to the permanent dentition because of the close relationship between the apices of primary teeth and the dev...

A method of recording incisor inclination is described using the Tooth inclination Protractor (TIP). This instrument was used to record incisor inclination on dental casts. The scores were related to traditionally determined inclinations for the upper incisor to maxillary plane and the lower incisor to mandibular plane from the lateral cephalometric radiograph. The TIP scores were closely relat...

PURPOSE We aimed to identify the risk factors associated with late aneurysmal sac expansion after endovascular abdominal aortic aneurysm repair (EVAR). METHODS We retrospectively reviewed contrast-enhanced computed tomography (CT) images of 143 patients who were followed for ≥6 months after EVAR. Sac expansion was defined as an increase in sac diameter of 5 mm relative to the preoperative dia...

After tooth loss, alveolar bone resorption occurs and causes soft tissue collapse. In the anterior maxilla, this situation becomes a great challenge. Bone volume must be reestablished to allow for proper implant placement. Another challenge is achieving primary closure and improving soft tissue esthetics. Nine patients who were partially edentulous in the anterior maxilla and received 10 palata...
