The Prevalence Of Hypodontia In Children With Cleft And Nonrelated Controls

The aim of this study was to compare the occurrence of hypodontia, dental age, and asymmetric dental development in children with cleft with a non- sibling control group. The study sample consisted of 30 children with cleft (aged 7.2 to 17.1 years) and 60 controls without cleft (aged between 7 and 18.8 years). Hypodontia, dental age, and asymmetric dental development were assessed on panoramic radiographs of the children with cleft and the control children without cleft. The cleft (p.001) group showed a significantly higher frequency of hypodontia and a significantly higher occurrence (cleft p.01) of asymmetric dental development, compared with the control group. Only a small, but insignificant delay in dental development could be found in the cleft group. The cleft subjects showed a significantly higher occurrence of hypodontia and asymmetric dental development than the non-cleft control group. This may suggest a genetic component for the occurrence of hypodontia and asymmetric dental development

Rezumat Osteodistracåia bimaxilarã -o metodã eficientã pentru corectarea deficitului transversal. Prezentare de caz Dizarmoniile dento-maxilare apar la pacienåii adulåi datoritã discrepanåei dintre dimensiunea dinåilor aei a osului subjacent fiind mai frecvent întâlnite în cazurile cu hipodezvoltare transversalã maxilarã si mandibularã. Tratamentul ortodontic clasic utilizeazã ca metodã de creare de spaåiu extracåiile dentare sau expansiunea arcadelor, care însã au dezavantaje estetice majore pentru pacienåi. Expansiunea palatinã rapidã asistatã chirurgical împreunã cu osteodistracåia medianã mandibularã reprezintã o metodã de avangardã în tratamentul ortodontic aei chirurgical al pacienåilor cu deficite transversale severe de dezvoltare al ambelor maxilare. Expansiunea obåinutã prin aceastã metodã este mai stabilã aei spaåiul generat este mult mai mare în comparaåie cu metoda convenåionalã ortodonticã. Cazul de faåã ilustreazã avantajele acestei proceduri chirurgicale, care asociatã cu un tratament ortodontic produce modificãri morfologice faciale majore aei ocluzale aei totodatã permite o aliniere dentarã armonioasã. Cuvinte cheie: expansiune palatinã rapidã asistatã chirurgical, osteodistracåie mandibularã medianã, deficit transversal bimaxilar, tratament ortodontic Abstract Severe dental crowding in adult patients is one of the features of disparity between the size of the teeth and the jaws. It is most frequently found in cases with a transverse hypoplasia of the maxilla and the mandible. The traditional orthodontic approach is extraction of teeth or arch expansion, both of them with major esthetic disadvantages for the patients. The surgically assisted maxillary expansion (SARME) and the mandibular midsymphyseal distraction osteogenesis procedures open new horizons for the orthodontists and maxillofacial surgeons in the effort to solve the esthetic demands of the patients with dental crowding and severe transversal discrepancy. The amount of surgical expansion is of higher magnitude and stability then the one achieved in orthodontic cases. The case presented here highlights the importance of the surgical procedure followed by the orthodontic therapy due to the enhancement in occlusion, dental alignment and facial morphology

Eagle syndrome surgical treatment with piezosurgery.

Eagle syndrome (ES) is an uncommon complication of styloid process elongation with stylohyoideal complex symptomatic calcification. It is an uncommon condition (4\% of the population) that is symptomatic in only 4\% of the cases. Eagle syndrome is usually an acquired condition that can be related to tonsillectomy or to a neck trauma. A type of ES is the styloid-carotid syndrome, a consequence of the irritation of pericarotid sympathetic fibers and compression on the carotid artery. Clinical manifestations are found most frequently after head turning and neck compression. Although conservative treatment (analgesics, anticonvulsants, antidepressants, local infiltration with steroids, or anesthetic agents) have been used, surgical treatment is often the only effective treatment in symptomatic cases.We present the case of a 55-year-old patient, successfully treated under endotracheal anesthesia. The cranial portion of the calcified styloid process was shortened through an external approach, using a piezoelectric cutting device (Piezosurgery Medical II; Mectron Medical Technology, Carasco, Italy) with MT1-10 insert, pump level 4, vibration level 7.No major postoperative complications such as nerve damage, hematoma, or wound dehiscence occurred. After 6 months, the patient was completely recovered. Two years after the surgery, the patient did not refer any symptoms related to ES.The transcervical surgical approach in patients with ES seems to be safe and effective, despite the remarkable risk for transient marginal mandibular nerve palsy. This risk can be decreased by the use of the piezoelectric device for its distinctive characteristics--such as precision, selective cut action, and bloodless cut

Effect of 3d element substitution on inter- and intragrain critical temperatures in (bi,pb):2223 system

The inter- and intragrain critical temperatures are differently affected by the natur and concentration of the 3d substituent (Fe,Ni,Zn) for Cu. Decrease of these temperatures is in agreement with the increase in residual resistivity.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Inclusion of all permanent mandibular molars and all maxillary second and third molars: a case report and review of the literature.

Simultaneous impactions of first, second, and third permanent molars on both mandibular sides together with the all maxillary second and third molars is a clinical situation never reported before in the literature and it might be a difficult challenge for maxillofacial surgeons and dentists. Early diagnosis and treatment of eruption disturbances contributes to optimal outcomes. This article reports the treatment of an adult with severe impaction of all mandibular first, second, and third molars together with all maxillary second and third molars, which limits the masticatory function and dental arch integrity. The impacted molars were surgically removed as the patients declined orthodontic treatment. The combined surgical-orthodontic approach represents a challenging treatment and the optimal one as it eliminates the need for prosthetic rehabilitation and implant replacement of the impacted molars, when accepted

Bimaxillary distraction osteogenesis used for treatment of crowding in non-growing individuals. Case report

Dental crowding is frequently associated with transverse jaw discrepancies, resulting in a less-than-ideal position of the teeth in the basal bone. The classic aproach for correcting bimaxillary crowding are extractions or arch expansion. Rapid maxilla-mandibular expansion was used to treat transverse discrepancies in growing patients, but with aging, the upper and lower jaw bones become increasingly resistant to expansion. The surgically assisted rapid maxillary expansion (SARME) and the mandibular midsymphyseal distraction osteogenesis procedure overcome this age limitation and are of great importance for the treatment of transverse discrepancies in adults. The aim of this paper is to report a case with a severe transverse deficiency treated with SARME, mandibular midsymphyseal distraction together with orthodontic treatment in an adult patient. The case highlights the esthetic advantages of increasing the transversal dimension of both jaws in patients with severe crowding associated with constricted dental arches and recommends the maxillo-mandibular transverse distraction osteogenesis as an and effective form of surgical treatment for patients with malocclusions or dentofacial deformities featuring severe transverse discrepancies, combined with a carefully monitored orthodontic treatment

Dental white spots associated with bulimia nervosa in orthodontic patients

Bulimia nervosa is an eating disorder characterized by consuming a large amount of food in a short amount of time followed by an attempt to rid oneself of the food consumed (purging), typically by vomiting, taking a laxative, diuretic, or stimulant, and/or excessive exercise, because of an extensive concern for body weight. The frequent contact between teeth and gastric acid, in particular, may cause: severe dental erosion, perimolysis, or the erosion of tooth enamel and swollen salivary glands. Constant vomiting can lead to gastroesophageal reflux. The aim of this article is to report two cases of patients with severe dental demineralization associated with bulimia nervosa during orthodontic treatment. Diagnosis and prevention aspects are highlighted and discussed
