Ad Hoc Networks are gaining popularity as a result of advances in smaller, more versatile and powerful mobile computing devices. The distinguishing feature of these networks is the universal mobility o f a l l hosts. This requires re-engineering of basic network services including reliable multicast communication. This paper considers the special case of(More)
OBJECTIVE To review predisposing factors contributing to dental caries in patients with cleft lip, cleft palate, or both (CL/P). DESIGN Patients with CL/P have a higher susceptibility to caries compared with the population group without clefts. A review of the literature was undertaken to determine factors that could account for the compromised oral(More)
OBJECTIVE To determine if the type of ligation influences the frictional resistance between stainless steel wire and brackets when the wire is subjected to repeated vertical displacements. METHODS Eight different types of ligation were used to secure a length of stainless steel wire in three stainless steel twin brackets. The wire was subjected to(More)
INTRODUCTION The aim of this study was to compare the efficiency of self-ligating (SL) and conventionally ligated (CL) brackets during the first 20 weeks of extraction treatment. METHODS Study models of 50 consecutive patients who had premolar extractions in the maxillary and/or mandibular arch, 0.022 x 0.028-in slot brackets, and similar archwire(More)
BACKGROUND Inferior periodontal and pulpal outcomes may follow surgical exposure of palatally impacted maxillary canines. OBJECTIVES To compare the periodontal and pulpal health of palatally impacted maxillary canines following either surgical exposure and assisted eruption (SE) or unassisted eruption following extraction of the overlying deciduous canine(More)
BACKGROUND Palatally impacted maxillary canines may appear unsightly after treatment because of changes in position and colour. AIM To determine if palatally impacted canines treated either by surgical exposure and orthodontic repositioning or by creation of space in the arch and unassisted eruption have different aesthetic outcomes. METHODS Twenty(More)
OBJECT Previous investigations of health outcome after spinal surgery for tethered cord syndrome (TCS) have been single-institution studies. The aim of this study was to report inpatient complications and outcomes on a nationwide level. METHODS The Nationwide Inpatient Sample (NIS) was used to identify patients who underwent spinal surgery for TCS in the(More)
OBJECTIVES To determine the variation in molar relationships when upper incisor angulations are altered in a Class I occlusion with normal overjet and overbite. MATERIALS AND METHODS Typodonts were set up to simulate a Class I occlusion on a normal skeletal base. The lower incisors were positioned normally at 92 degrees to the mandibular plane and the(More)
