Tooth size arch length discrepancy (TSALD) is a well defined means of assessing dental crowding. In previous literature conflicting evidence exists regarding the part played by tooth size and arch dimension in causing dental crowding. The objective of present study were to; examine the relationship between tooth size and arch dimension in crowded and non crowded arches, and to find out the majo...

A 63-year-old Chinese man was referred to our institution with complaints of intermittent cough, hoarseness and dyspnea for more than 1 week. He visited 2 community clinics and received irregular antibiotic therapy, but the symptoms aggravated gradually. He had no history of hypertension. On examination, his heart rate was 108 beats per minute, blood pressure was 112/80 mm Hg, his respiratory r...

In a recent paper we examined a model of an arch bridge with viscous damping subjected to a sinusoidally varying central load. We showed how this yields a useful archetypal oscillator which can be used to study the transition from smooth to discontinuous dynamics as a parameter, alpha, tends to zero. Decreasing this smoothness parameter (a non-dimensional measure of the span of the arch) change...

OBJECTIVES To study maxillary arch width in adult patients with bilateral cleft lip and alveolus (BCLA) or with complete bilateral cleft lip and palate (BCLP), who have not had any surgery. SETTING AND SAMPLING POPULATION: Eighteen patients with BCLA, 13 patients with BCLP, and 24 controls from remote areas of Indonesia collected over 10 years. MATERIALS AND METHODS Dental casts were digitize...

Dento-alveolar disharmony with crowding is a common reason for orthodontic treatment not fully understood or unequivocally demonstrated causes. This study investigated the correlations between teeth dimensions, arch lengths, and during mixed dentition period. A cross-sectional on 100 dental casts of patients class I malocclusions was performed. Dental arches were classified as non-crowded, mode...

The contribution of interdigitation to the development of the dentition of juvenile Macaca fascicularis was studied on a series of dental casts and at the histological level by the use of vital staining. Fourteen laboratory-born monkeys were allocated to a control group (n = 7) or an experimental group (n = 7). They were followed from 31 to 152 weeks of age. In the animals of the experimental g...

PURPOSE Dental crowding occurring in the anterior part of the mandible in the early mixed dentition has been a subject of increasing concern for child patients, their parents, and the pediatric dentist. The aim of this study was to evaluate indicators of crowding found at the primary dentition, which may lead to the future manifestation of crowding at the anterior part of the mandibular arch in...
