OBJECTIVES To obtain maxillary anterior tooth dimension and proportion values for the Central Chinese population and to evaluate the existence of sexual dimorphism, any consistent relationships between the tooth ratios, and the presence of golden proportions. METHODS Tooth dimensions and proportions of six maxillary anterior teeth were recorded on gypsum casts obtained from 147 subjects (82 w...

The aim of the present study was to evaluate the periodontal conditions of anterior teeth that presented pathologic migration in patients with chronic periodontitis and to compare periodontal destruction in migrated versus non-migrated teeth. The sample included 32 patients of both sexes (mean age: 46.0 +/- 11.6 years) diagnosed with generalized chronic periodontitis and selected on the basis o...

This clinical study examined objective smile parameters in the natural anterior dentition. Standardized intraoral and extraoral photographs were taken of 106 Caucasian adults (54 women, 52 men) with a healthy dentition. The following parameters were analyzed: correlation of dental and facial midline, upper lip position and curvature, relationship of the maxillary anterior incisal curve with low...

BACKGROUND The present paper describes the oral manifestations in a 16-year-old boy previously diagnosed with Apert syndrome. PATIENT AND METHODS The extraoral and intraoral pathological findings were recorded. The following intraoral parameters were recorded: plaque and calculus deposits, dental caries, periodontal status, malpositions, and occlusion. For the upper anterior teeth, dental sha...

CASE REPORT A four year old girl reported to the Department of Pedodontics and Preventive Dentistry with a complaint of missing upper anterior teeth. On examination, 52, 51 and 61 were found to be absent [Table/ Fig-1, 2]. An investigation revealed that these teeth were avulsed during a traumatic fall which had taken place about six months ago. The patient had not visited a dentist after the in...

Schwartz ('74) proposed revised homologies of the deciduous and permanent anterior teeth in living lemuriform primates of the family Indriidae. Gingerich ('77) described a juvenile specimen of Avahi and emphasized the importance of functional integrity in controlling the pattern of dental reduction in primates, neither of which supports Schwartz's interpretation. Schwartz ('78) recently reitera...

conclusions it was concluded that the prevalence of traumatic dental injuries was 9.3%. traumatic dental injuries among children exhibit complex interaction between the victims’ oral conditions and their behavior. therefore, prevention should consider a number of characteristics such as oral predisposing factors, environmental determinants and human behavior. it is recommended that specific and...

In this study, the number and location of remaining teeth were analyzed according to sociodemographic variables, anthropometric measurements, and oral health behavior patterns. The hypothesis was that the number and location of remaining teeth would be affected by oral health behavior and by sociodemographic factors, such as education levels, household income, and urban/rural residency.This nat...
