PURPOSE The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. MATERIALS AND METHODS Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam com...

A The discerning orthodontist has a treatment regimen that preferentially deals with arch deficiencies and might not necessitate extractions. Orthodontic expansion has been shown to be predictably unstable, and interproximal reduction is effective only up to a point, and so most of us use skeletal expansion in some form or another. This article is an effort to gather from the literature and per...

Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment protocol. Maxillary second molars are recognized as usually having a single palatal root with a single palatal canal. The incidence of second palatal root in the maxillary second molar is very rare. Two cases are presented in this paper describing the endodontic management of a fou...

The aim of this study was to assess, by a digital photogrammetric technique, the relative dimensional changes before and after rapid maxillary expansion (RME). The transverse diameters and volumetric variations of the palate were measured by photogrammetry on study casts taken at three different phases of therapy: at the beginning of treatment (T1), on removal of the rapid expander, after expan...

Background: Palatal rugae are irregular and non-identical mucosal elevations seen on anterior third of palate. They are arranged in transverse direction on either side of Median Palatine Raphe [MPR]. Though they are the most stable anatomical structures in the oral cavity, certain conditions like orthodontic treatment contribute to some amount of variations in their pattern qualitatively. Durin...

statement of the problem: refractory nocturnal enuresis possesses a heavy psychosocial burden for the affected child. only a 15% spontaneous annual cure rate is reported. purpose: this patient-level meta-analysis aimed to evaluate the efficacy of rapid palatal expansion to treat nocturnal enuresis among children. materials and method: a sensitive search of electronic databases of pubmed (since ...

The aim of this study was to identify factors that affect the treatment duration and predict forced eruption in impacted maxillary canines using panoramic radiographs cone-beam computed tomography. This retrospective performed by reviewing medical records 73 patients (93 canines) from age 8 18 years who were treated with surgical orthodontic interventions on January 2012 December 2020 Ajou Univ...
