[Ab] Abstract:The aim of this study is to investigate the biomechanics for orthodontic tooth movement (OTM) subjected to concurrent single-tooth vibration (50Hz) with conventional orthodontic force application, via a clinical study and computational simulation. Thirteen patients were recruited in the clinical study, which involved distal retraction of maxillary canines with 1.5N (150g) force for 12weeks. In a split mouth study, vibration and non-vibration sides were randomly assigned to each subject. Vibration of 50Hz, of approximately 0.2N (20g) of magnitude, was applied on the buccal surface of maxillary canine for the vibration group. A mode-based steady-state dynamic finite element analysis (FEA) was conducted based on an anatomically detailed model, complying with the clinical protocol. Both the amounts of space closure and canine distalization of the vibration group were significantly higher than those of the control group, as measured intra-orally or on models (p<0.05). Therefore it is indicated that a 50Hz and 20g single-tooth vibration can accelerate maxillary canine retraction. The volume-average hydrostatic stress (VHS) in the periodontal ligament (PDL) was computationally calculated to be higher with vibration compared with the control group for maxillary teeth and for both linguo-buccal and mesial-distal directions. An increase in vibratory frequency further amplified the PDL response before reaching a local natural frequency. An amplification of PDL response was also shown to be induced by vibration based on computational simulation. The vibration-enhanced OTM can be described by mild, vigorous and diminishing zones among which the mild zone is considered to be clinically beneficial.

[Ab] Abstract:Background. Melnick-Needles Syndrome is rare congenital hereditary skeletal dysplasia caused by mutations in the FLNA gene, which codifies the protein filamin A. This condition leads to serious skeletal abnormalities, including the stomatognathic region. Case Presentation. This paper describes the case of a 13-year-old girl diagnosed with Melnick-Needles Syndrome presenting with different forms of skeletal dysplasia, such as cranial hyperostosis, short upper limbs, bowed long bones, metaphyseal thickening, genu valgum (knock-knee), shortened distal phalanges, narrow pelvis and shoulders, rib tapering and irregularities, elongation of the vertebrae, kyphoscoliosis, micrognathia, hypoplastic coronoid processes of the mandible, left stylohyoid ligament suggesting ossification, and dental development anomalies. Conclusion. Knowledge of this rare syndrome on the part of dentists is important due to the fact that this condition involves severe abnormalities of the stomatognathic system that cause an impact on the development of the entire face as well as functional and esthetic impairments.

[Ab] Abstract:Introduction It is known that the basal sound promotes shortening and adduction of the vocal folds and leaves the mucosa looser. However there are few studies that address the supralaryngeal physiological findings obtained using the technique. Objective To check the effectiveness of using vocal fry on the voice and velopharingeal port closure of five adult subjects, whose cleft palate has been corrected with surgery. Methods Case study with five subjects who underwent otolaryngology examination by means of nasopharyngoscopy for imaging and measurement of the region of velopharyngeal port closure before and after using the vocal fry technique for three minutes. During the exam, the subjects sustained the isolated vowel /a:/ in their usual pitch and loudness. The emission of the vowel /a:/ was also used for perceptual analysis and spectrographic evaluation of their voices. Results Four subjects had an improvement in the region of velopharyngeal port closure; the results of the spectrographic evaluation were indicative of decreased hypernasality, and the results of the auditory-perceptual analysis suggested improved overall vocal quality, adequacy of loudness, decreased hypernasality, improvement of type of voice and decreased hoarseness. Conclusion This study showed a positive effect of vocal fry on voice and greater velopharyngeal port closure.

[Ab] Abstract:Cleido-cranial dysplasia, often referred to as Scheuthauer-Marie-Sainton syndrome, is an autosomal dominant disorder of the musculo-skeletal system. Patients with cleido-cranial dysplasia are characterized by short stature, frequent varus or valgus hip, kyphoscoliosis, underdevelopment of the scapulas and the sternum, incorrect number of ribs. The most characteristic feature is unilateral or bilateral, partial or total underdevelopment of clavicles. Mental development is not affected in this syndrome. Malocclusion, occlusal irregularities, multiple supernumerary teeth, impacted teeth, and persistent milk teeth are found in the stomatognathic system. Teeth often have abnormal anatomy. Gothic palate, cleft hard and soft palate are diagnosed. The aim of this paper is to present a case of a 12-year-old boy diagnosed with irregularities in the masticatory system involving an additional number of retained teeth. The boy was referred by an orthodontist for surgical and orthodontic team therapy. The case presented confirms the observations of other authors that only the multi-specialty collaboration of a pediatrician, a geneticist, an orthopedist, an orthodontist, a maxillofacial surgeon, an implant prosthetic surgeon and a physiotherapist can provide proper diagnosis and treatment.

[Ab] Abstract:Oral rehabilitation of patients with craniofacial disorders is a great challenge and needs a multidisciplinary approach. This is due to the diverse etiology of the disease and severity of changes in tissues and organs. Congenital absence of tooth germs manifested in the form of oligodontia or anodontia, the presence of persistent deciduous teeth in ectodermal dysplasia (ED), cleft lip and hard palate or cancer-induced changes in the tissues of the stomatognathic system are the most common causes of these disorders. The observed abnormalities are responsible for functional disorders of musculo-articular system, speech and chewing. In addition, noticeable adverse changes in the appearance have a huge psychological impact on patients and their well-being. Therefore, the treatment of these medical conditions should begin in childhood and comprise interdisciplinary rehabilitation, involving prosthetics and orthodontics supported by surgery, as well as speech or laryngological therapy. In this paper the interdisciplinary treatment of patients with oral hard and soft tissues disorders during ectodermal dysplasia is discussed. Early oral rehabilitation can restore lost or abnormally shaped tissues and proper functions of the masticatory system. It can also have a positive impact on further physical and psychological development of patients.

[Ab] Abstract:BACKGROUND: The high frequency of alterations of the stomatognathic system associated with premature birth may suggest that prematurity is an important risk factor in the development of this system. Prematurity has an incidence between 6-11% of births and is associated with factors such as genetic, maternal conditions (obstetric problems, nutritional status, infections) and antenatal care. In addition, undesirable situations, such as changes in enamel and the development of the skeletal structure, also appears to be associated with prematurity. This study aimed to look for changes in the stomatognathic system at five years of age associated with premature birth. METHODS: We estimated the prevalence of developmental disorders of the stomatognathic system in the primary dentition of preschool children at five years of age. Changes in preterm infants (n = 32) compared with term born (n = 381) were evaluated . Clinical examinations and questionnaire with sociodemographic and health of mothers and children information. Gestational age, birth weight, head circumference, Apgar score and mechanical ventilation, were collected from the medical records to birth records. The explanatory variable was preterm (<37 weeks gestational age). RESULTS: Prevalence of 7.7% of preterm infants was found. Of these, 40.6% had atresic palate, 56.2% malocclusion and 21.8% enamel hypoplasia. Forty (9.6%) children were not breastfed at the breast, and 26 (65.0%) had some type of malocclusion, showing association between not breastfeeding with an abnormal development of the stomatognathic system. The group of preterm infants showed five times more changes in head circumference and three times more mechanical ventilation use at birth. Change in head circumference at birth and mechanical ventilation has a significant association between groups of preterm and term infants. CONCLUSIONS: Mechanical ventilation at birth directly contributed to an increased risk of developmental disorders of the stomatognathic system in preterm infants, especially dental hypoplasia. Non-breastfed children had a higher risk of developing malocclusion. Alterations in head circumference were related effective on dental malocclusion. The results suggest that changes in the stomatognathic system are influenced by premature birth and points to the imperative need of using methods of preventive.

[Ab] Abstract:OBJECTIVE: To establish a model of three-dimensional (3-D) cephalometric analysis to study dentomaxillofacial deformities. METHODS: Between January 2012 and October 2013, 15 patients with dentomaxillofacial deformities were treated using 3-D cephalometric analysis in orthognathic surgery plan. There were 7 males and 8 females with an average age of 23.6 years (range, 17-37 years), including 4 cases of mandibular protrusion with maxillary deficiency, 4 cases of maxillary protrusion with mandibular deficiency, 2 cases of long face syndrome, and 5 cases of facial asymmetry. CT images were reconstructed by Mimics software. The anatomical landmarks were located, the reference planes and analysis planes were defined and the 3-D coordinate was established. The distance and degree between landmarks and analysis planes which defined in the measure project were measured. RESULTS: Based on the 3-D CT quantitative analysis methods, cephalometric analysis project was defined in the 3-D coordinate. 3-D cephalometric analysis provided a convenient and precise method for the clinical measurement of dentomaxillofacial morphology, and reduce the time in preoperation analysis. CONCLUSION: The model of 3-D CT cephalometric analysis can provide precise information in the diagnosis and treatment planning of orthognathic surgery.

[Ab] Abstract:Sixty-six guinea pigs with dental disease were presented to the University of Veterinary Medicine, Vienna, Austria, from 2006 to 2010. Almost all patients had a history of eating difficulties (95 per cent) and underwent clinical and oral examination as well as CT of the head. Findings on extra- and intraoral examination were asymmetric elongation (n=28) and symmetric bridging (n=24) of cheek teeth, obliquely worn incisors (n=17), palpable lower jaw swellings (n=13), exophthalmos (n=10) and incisor macrodontia (n=6). Eighty per cent of guinea pigs with exophthalmos showed ipsilateral periapical disease of the maxillary cheek teeth on CT. Ninety-two per cent of patients with palpable lower jaw swellings showed corresponding dental pathologies on CT. Periapical disease of incisors (n=11) and cheek teeth (n=32) were the most common findings on CT. All abnormally large incisors were found on oral examination and CT, but macrodontia of cheek teeth could only be visualised by CT. Deviation of the lower jaw evaluated in awake animals by visual inspection appeared to correlate with cheek teeth abnormalities. Results emphasise the importance of diagnostic imaging, in particular CT, in guinea pigs with dental disease in order to localise lesions and underlying aetiologies.

[Ab] Abstract:The aim of the present study was determine the type of bite and abnormalities in the vertical dimension of occlusion (VDO) among children and adolescents with temporomandibular disorder (TMD). The Helkimo index was employed for the diagnostic investigation of TMD. A clinical examination was performed for the determination of occlusion. The VDO was measured using a digital caliper. Fisher's exact text was used to determine associations between type of bite, gender and TMD. The Student's t-test was used to compare age and VDO by gender. The significance level was set to 5% or corresponding p-value. Children and adolescents with anterior open bite were 1.2-fold more likely to develop TMD in comparison to those without any type of malocclusion. The same was found for those with posterior crossbite and mixed malocclusion. A statistically significant association was found between the VDO and age in both genders. TMD affected 68.85% of the sample. No correlation was found between malocclusion, VDO and TMD in the sample. The present findings suggest that individuals with malocclusion are more prone to TMD. Therefore, it is important to evaluate all variables capable of influencing the harmony of the stomatognathic system for an effective diagnosis of TMD and malocclusion.
