Pain Threshold of Human Anterior Teeth to Pressure Stimulation
… method of measuring the pain threshold of human teeth and to study the relationship of variables such as age and sex with pain threshold of teeth. A procedure was developed to measure the pain threshold to mechanical stimulation applied as a force with a push gauge. An analysis of the data …

Periodontal Health of Anterior Teeth with Two Types of Fixed Retainers
Introduction: Fixed retainers for anterior teeth have become a popular method for maintaining the position and function of teeth after orthodontic treatment. Various retainer designs, wire sizes and types have been used over the years. One problem with fixed retainers is that they complicate oral …

Comparison of Maxillary Anterior Teeth Width to Facial Dimensions among Three Races
… appropriate esthetic dimensions of the maxillary anterior teeth is an important aspect in fixed and removable prosthodontics. The proportion of facial structures and the relationship between facial measurements and natural teeth could provide additional guidance in selecting denture teeth as well …

A computerized analysis of anterior teeth as a possible indicator of age, race and sex
… of age, race or sex; The computerized study of anterior tooth positions is an attempt at further elucidation of age, race and sex characteristics. Bite marks in wax from a general population sample of known age, race and sex are the basis for this computerized study. The computerized procedure …

A randomised controlled trial to assess the pain associated with the debond of orthodontic fixed appliances
… pain experienced when debonding the posterior teeth (P=<.05). 39% found the lower anterior teeth the most painful. The expected pain was significantly greater than that actually experienced (P=<.001). Greater pain during treatment correlated with increased expectations and increased actually …

The Prevalence of the Need for Esthetic Crown Lengthening in Post Orthodontically Treated Subjects
… the size relationship of the clinical crowns of teeth, in an orthodontic population, we can begin to quantify their need for periodontal plastic surgery. In this two part study, 200 plaster models were used as subjects, followed by a clinical exam of 31 of those subjects. These models represented …

Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
<p><em>Introduction: </em>Changes occurring in anterior alveolar bone following orthodontic tooth movement are controversial. Some research has shown that orthodontic tooth movement results in the adaptation of cortical bone; others have shown that it results in dehiscence and fenestrations.</p> …

The localisation of Experimentally Evoked Dental Pain : an exploration of an intervention to improve the accuracy of localisation
… years). All were healthy and dentate. Maxillary teeth were stimulated using the following procedures in all of the studies: electrical stimuli were delivered to teeth through customised bipolar electrodes in a random order. The first study was carried out on anterior and posterior teeth at the …

Treatment of Enamel Demineralization Following Orthodontic Therapy
… white-spot lesion is a common finding on teeth in patients who have received orthodontic treatment. Recently, a calciumphosphate (Ca-P) treatment was developed to enhance remineralization of white spot lesions. We hypothesized that a rinse containing the Ca-P would promote greater …
