BACKGROUND Studies dating to the 1870s have demonstrated that long-term nonnutritive sucking habits may lead to occlusal abnormalities, including open bite and posterior crossbite. However, little is known as to whether habits of shorter durations have lasting effects. METHODS The authors collected longitudinal data on nonnutritive sucking among children(More)
The purpose of this study was to evaluate on a longitudinal basis, the changes in intercanine and intermolar widths over a 45-year span. The subjects in this study were from two pools of normal persons: (1) 28 male and 33 female infants evaluated longitudinally at approximately 6 weeks, 1 year, and 2 years of age (before the complete eruption of the(More)
Long-term use of orotracheal tubes has been associated with palatal groove formation, acquired cleft palate, and defective primary dentition. To determine the incidence of palatal groove formation, maxillary impressions were made of 63 neonates and infants who required orotracheal intubation for one to 62 days. A palatal groove was present in 47.6% of these(More)
A group of 43 patients with AD (mean age, 13.5; SD, 5.9 yrs) was identified from the University Hospital School Pediatric Dentistry Clinic. We reviewed the patients' charts to obtain demographic data, dental findings, and the management techniques used for treatment. The patients were divided into groups according to Frankl's categories of behavior, ranging(More)
Dental publications on autism have been sparse since the first comprehensive article geared for the dental profession. New findings on the etiology of autistic disorder (AD) have been discovered, suggesting that it is an organic disorder characterized by abnormalities in the brain, especially the cerebellum and limbic system. This article summarizes the(More)
Inability to vomit has been cited as characteristic of Prader-Willi syndrome (PWS). Although post-prandial vomiting after gastric by-pass surgery has been reported, neither vomiting under "typical" circumstances or rumination have been described. Prompted by the discovery of several cases of vomiting and rumination, a questionnaire was sent to members of(More)
Four hundred twenty-two children (Caucasians, Asians, and blacks) aged 6 weeks to 36 months were recruited. Five measurements (incisal edge distance, alveolar crest distance, closed mouth breadth, open mouth breadth, and nose-lip distance) were made by two calibrated examiners and an average was recorded. Because there were no statistically significant(More)
The long-term use of orotracheal tubes in infants has been associated with airway damage, palatal groove formation, acquired cleft palate, and defective primary dentition. Nasotracheal intubation is associated with trauma to the nasal septum and deformities of the nares. Because the infant is an obligatory nose-breather, nasogastric feeding tubes obstruct(More)
