OBJECTIVES To test the applicability of the Tanaka and Johnston prediction method in a Saudi population. METHODS The current study was conducted at the College of Dentistry, King Saud University, Riyadh, Saudi Arabia from September 2013 to January 2014, on a sample of 409 pairs of orthodontic study models. The mesiodistal width of the mandibular permanent incisors, permanent canines, and perm...

Objectives The purpose of this study was to present a case of regenerative endodontic procedure. Case The maxillary 1st premolar of a 9-year-old patient was diagnosed as necrotic. Since the tooth was immature, we decided to treat this tooth with regenerative endodontic procedure. After disinfection of the canal, bleeding was induced by lacerating the peri-apical tissues ...

Objective: To evaluate and compare the long-term skeletodental stability of mandibular symphyseal distraction osteogenesis (MSDO) achieved with the use of tooth-borne versus hybrid distraction appliances. Materials and Methods: Posttreatment and follow-up orthodontic records were collected for 33 patients. The 14 patients who underwent distraction with a tooth-borne appliance had a mean follow-...

OBJECTIVE Provide reference basis for the clinical implant restoration to select implant diameter through measuring each data of 7 teeth in the dental neck of bilateral upper and lower jaws of the young volunteers with normal dentition. METHODS Select 30 healthy young volunteers with complete dentition but no malocclusion, take cone beam CT (CBCT), measure the mesiodistal and buccolingual dis...

OBJECTIVES The aim of the investigation was to examine the forms of the crowns in the maxillary anterior tooth segment and corresponding gingival characteristics among healthy Taiwanese subjects. MATERIALS AND METHODS The crown width at the apical third (CW), length (CL), gingival angle (GA) and the interdental papilla height were assessed from the diagnostic stone model using a calibrated pe...

Introduction: Predicting the size of unerupted teeth during the mixed dentition period is a critical factor in managing the developing occlusion. The Nance radiographic method, Moyers mixed dentition space analysis and Johnston Tanaka method are among the most commonly used in clinical practice for detecting tooth sizearch length discrepancies. In view of reported secular trends, racial, and se...

OBJECTIVES The dental development of permanent mandibular teeth in a small group of children with dystrophic epidermolysis bullosa (DEB) was assessed from radiographs and compared to a healthy, age-and-sex-matched control group. METHODS This was a retrospective radiographic cross-sectional study. The sample consisted of a group of 44 children aged between 4 and 15 years with DEB and healthy, ...

Clinical studies suggest that maternal smoking during pregnancy can reduce the crown size of the child's teeth. Delayed dental age compared with chronological age has also been reported in children whose parents smoke. Among the main components of tobacco smoke are nonhalogenated polycyclic aromatic hydrocarbons (PAHs), many of which are highly toxic. Humans are exposed to PAH compounds mainly ...

Background: Sex determination using dental features is primarily based upon the comparison of tooth dimensions in males and females. Aims and Objectives: To determine the role of inter-canine width in identification of sex of individuals. Methods: 50 subjects were included in the study. Impressions were taken with alginate and study models prepared. Inter canine width was measured in all the ca...

Detailed oro-maxillofacial studies using dental casts, pantomograms and cephalograms were performed in 28 patients with Turner's syndrome and compared statistically to the results from 23 normal short children. Small tooth crown size, short tooth roots and advanced dental age were characteristic of patients with Turner's syndrome. However, the incidence of peg shaped teeth, malocclusion, high a...
