The population belongs pediatric between 5 and 15 years, who have DMA, trea-ted southern metropolitan h...
OBJECTIVES The distinct effect of exclusive and predominant breastfeeding on primary dentition malocclusions is still unclear. We hypothesized that exclusive breastfeeding presents a higher protective effect against malocclusions than predominant breastfeeding and that the use of a pacifier modifies the association between breastfeeding and primary dentition malocclusions. METHODS An oral hea...
AIM The purpose of this case report is to present the esthetic and functional rehabilitation of the teeth in a 20-year-old patient with amelogenesis imperfecta (AI), facial asymmetry due to functional mandibular shift, and unilateral posterior crossbite. BACKGROUND AI is a group of hereditary defects of enamel unassociated with any other generalized defects. AI results in poor development or ...
The aim of this study was to evaluate the influence of prolonged sucking habits and mouth breathing on palatal vault morphology in a group of subjects with unilateral functional crossbite [crossbite (CB) group] compared with a group of subjects with normal occlusion [non-crossbite (NCB) group]. A sample of 80 Caucasian subjects (51 CB and 29 NCB; aged 5.3 ± 0.8 years) in the deciduous dentition...
“Clinical Showcase” is a series of pictorial essays that focus on the technical art of clinical dentistry. The section features step-by-step case demonstrations of clinical problems encountered in dental practice. If you would like to contribute to this section, contact editorin-chief Dr. John O’Keefe at [email protected]. Anterior crossbite is an occlusal problem with functional and esthetic ...
Achondroplasia is the most common cause of dwarfism, which is inherited as an autosomal dominant disorder, caused by genetic mutation in fibroblast growth factor 3, leading to defective maturation of chondrocytes. It is known to be associated with various oral and dental manifestations such as delayed dental development, midfacial hypoplasia and constricted maxilla with a relatively large mandi...
ge Can the transverse dimensions of the dental arches be widened in a stable fashion over the long term? This question continues to challenge clinicians and researchers. Most orthodontists cite the correction of crossbite as the primary reason for altering the transverse dimension with rapid maxillary expansion (RME). A less obvious but more common orthodontic problem, whose etiology in part is...
AIM To determine the possible correlation between otitis media and dental malocclusion in children. METHODS Fifty subjects (26 males and 24 females; mean age: 7.8 +/- 1 years) were assessed: 25 patients, with otitis media formed the study group, while 25 healthy subjects formed the control group. An otolaryngological examination and dental cast measurements were performed in order to evaluate...
The objective of this study was to investigate whether skeletal mandibular asymmetry associated with unilateral and anterior crossbite will lead to lip asymmetry. The subjects were 26 females, 13 controls and 13 true skeletal asymmetric age-matched patients (24-50 years). The study group was diagnosed as asymmetric according to visual and panoramic radiographic examination and exhibited a unila...
The aim of this cross-sectional study was to determine the prevalence of malocclusions, occlusal traits, and their gender distribution in urban Iranian school children. Five hundred and two subjects (253 females and 249 males, aged 11-14 years) were examined. Molar relationship, overjet (OJ), overbite, midline deviation, crossbite, and crowding/spacing were recorded. Gender dimorphism was evalu...
