Risk of persistent palatal fistula in patients with cleft palate.

Importance: Many individuals with a cleft palate also have an associated craniofacial syndrome or anomaly.

Objective: To investigate the predictive associations of persistent palatal fistulas in patients with previously repaired cleft palate.

Design, Setting, And Participants: We performed a case-control study of patients with cleft palate repairs from January 1, 1986, through December 31, 2000, at a major tertiary care hospital center in the Bronx, New York.

Improvement in smile esthetics following orthodontic treatment: a retrospective study utilizing standardized smile analysis.

Objective: To quantify smile esthetics following orthodontic treatment and determine whether these changes are correlated to the severity of the initial malocclusion.

Materials And Methods: A standardized smile mesh analysis that evaluated nine lip-tooth characteristics was applied to two groups of successfully treated patients: group 1 (initial American Board of Orthodontics Discrepancy Index [DI] score<20) and group 2 (initial DI score>20). T-tests were used to detect significant differences between the low-DI and high-DI groups for baseline pretreatment measurements, baseline posttreatment measurements, and changes from pre- to posttreatment.

Clinical acceptability of two self-etch adhesive resins for the bonding of orthodontic brackets to enamel.

Objective: To determine whether two self-adhesive resin cements, Clearfil SA and RelyX, can be used to successfully bond orthodontic brackets to enamel.

Materials And Methods: Seventy extracted premolars were custom mounted, cleaned and randomly divided into three groups. In group 1 (control), orthodontic brackets were bonded to 25 premolars using the Transbond Plus and Transbond XT two step adhesive systerm adhesive.

Clinical case report: a multidisciplinary solution to a complex restorative problem and a macro-esthetic dilemma.

The restoration of facial harmony and establishment of a functional occlusion can pose unique problems in the treatment of complex dentoskeletal malformations. The advantages offered by the conjoint treatment planning, proper treatment sequencing, and the cooperation of various dental providers can create the best solutions for complex problems in patients. This case presentation demonstrates the interdisciplinary approach used by implant and restorative dentists, oral and maxillofacial surgeons, and orthodontists in a case that required "thinking outside the box" for optimal functional and esthetic solutions.

Root and pulp response after intentional injury from miniscrew placement.

Introduction: The purpose of this study was to evaluate the effects on the pulp and supporting tissues when miniscrews severely abrade the root surface.

Methods: Sixty self-drilling and self-tapping miniscrews were placed between the premolars and molars of 3 beagles (20 miniscrews per dog). The miniscrews were placed according to the protocol suggested by the manufacturer, but with the intention of inflicting root damage.

Forces of various nickel titanium closed coil springs.

Objective: To compare the forces generated by 14 different 9 mm springs supplied by five different companies.

Materials And Methods: Five replicates of 14 different 9 mm springs were evaluated, resulting in 70 total specimens. Each was extended once from its resting length to 12 mm and then was deactivated.

Cementum, pulp, periodontal ligament, and bone response after direct injury with orthodontic anchorage screws: a histomorphologic study in an animal model.

Purpose: To assess the histologic response of the periodontium, cementum, and pulp after intentional root injury with titanium screws.

Materials And Methods: Three female beagle dogs were used, and a total of 60 self-drilling/self-tapping miniscrews were manually inserted into the maxilla and the mandible with the intention of placement in close proximity or in direct contact with the roots. Digital radiographs were taken to select the sites with root injuries.

Treatment of obstructive sleep apnea with combined orthognathic-orthodontic approach assessed by nocturnal polysomnography.

This paper presents an evaluation of the effect of surgical mandibular advancement on obstructive sleep apnea (OSA) by sequential nocturnal polysomnography (NPSG). The case of a patient who had undergone several unsuccessful approaches is presented. The main outcome measures were assessed by the functional, occlusal, radiographic and esthetic changes achieved and also by reduction in the Apnea Hypopnea Index.

Craniofacial characteristics evidenced in Bartsocas-Papas syndrome from birth to five years. Case report.

Bartsocas-Papas Syndrome (BPS) is a rare congenital disorder, first described in 1972. It is usually characterized by neonatal or intrauterine death, and, as such, only 26 cases have been reported. Physical manifestations such as antecubital and popliteal pterygia (webbing), syndactyly of fingers, toes and talipes are frequently reported.

Dento-skeletal implications of Klippel-Feil syndrome [a case report].

Klippel-Feil syndrome is a disorder characterized by failure of normal segmentation of any two of the seven cervical vertebrae. It presents with a high frequency of cleft lip and/or palate and occasional oligodontia in both the primary and permanent dentition, craniofacial asymmetry, maxillary constriction and velopharyngeal insufficiency.
