Unusual Presentation of Juvenile Rhabdomyosarcoma in the Temporomandibular Area: A Case Report

Rhabdomyosarcoma frequently affects the craniofacial region with a rapid growing pattern that usually results in swelling of the interested area. The present paper describes a peculiar occurrence of rhabdomyosarcoma in a 12-year-old boy and the importance of a careful evaluation of clinical history to choose the correct diagnostic strategy. The patient was evaluated in the orthodontics section of the Dental School of the University of Bologna by an orofacial pain specialist, with a compliance of excruciating pain around the right ear that occurred 4 months earlier after a sports trauma. The patient had been previously evaluated by a pediatrician and an ENT specialist who requested a computerized tomography that did not show pathological conditions in the head/neck district. The drug therapy for pain control was not effective. The clinical examination showed a severe limitation of mouth opening, periauricular paresthesia and mandibular hyperalgesia on the right side. The patient reported intermittent, very intense stabs of pain occurring every 5 min, with a continuous dull pain in the temporal area. A nuclear magnetic resonance was requested and showed the presence of a solid expansive lesion in the right pterygoid area that eroded the cranial base and the medial portion of the mandibular condyle. An incisional biopsy led to the diagnosis of embryonal rhabdomyosarcoma. This case report emphasizes the importance of not underestimating the presence of pain in young subjects, suggesting a proper approach to apparently simple clinical cases

Effect of fixed orthodontic appliances on salivary properties

Objective. The purpose of this study was to evaluate the effect of fixed orthodontic appliances on the salivary flow rate, pH and buffer capacity after 1 year from bracket placement. Material and methods.The study population consisted of 20 healthy patients (mean age 16.5 \ub1 4 years) scheduled for fixed orthodontic treatment. Salivary samples were taken just before bracket placement (T0; baseline assessment) and after 1 year of treatment (T1; treatment assessment) using the GC Saliva-Check Kit (GC Corp., Belgium). Results. No statistically significant differences were detected for all the examined salivary properties between T0 and T1. Conclusions. Fixed orthodontic appliances did not have any effect on the flow rate, pH and buffer capacity of saliva after 1 year of fixed orthodontic treatment in the study sample

Does clinical experience affect the reproducibility of cervical vertebrae maturation method?

To assess interobserver and intraobserver reproducibility of the cervical vertebrae maturation method (CVMM) among three panels of judges with different levels of orthodontic experience (OE)

Bone Modeling after Orthodontic Extrusion: A Histomorphometric Pilot Study

During osteogenesis and bone modeling, high vascularity and osteoblastic/osteoclastic cell activity have been detected. A decrease in this activity is a sign of complete bone formation and maturation. Alveolar bone maturation seems to occur within weeks and months; however, the precise timing of the alveolar bone modeling is still unknown. The aim of this clinical pilot study was to investigate the bone modeling of neo-apposed tissue during orthodontic extrusive movements, through a histomorphometric analysis of human biopsies. This study was conducted on third mandibular molars sockets, and all teeth were extracted after orthodontic extrusion between 2010 and 2014. After different stabilization timings, extractions were performed, and a specimen of neo-deposed bone was harvested from each socket for the histomorphometric analysis. Histological parameters were evaluated to identify bone quantity and quality. This study included 12 teeth extracted from 9 patients. All specimens were composed of bone tissue. Bone samples taken after 1 and 1.5 months of stabilization presented remarkable percentages of woven bone, while after 2 months, a relevant decrease was observed. Histomorphometric analysis suggested that after orthodontic extrusion, a period of stabilization of 2 months allows the neo-deposed bone to mature

Elongated styloid process evaluation on digital panoramic radiograph in a North Italian population

The aim of this study is to evaluate the prevalence of elongated styloid process in digital panoramic radiographs in a North Italian population in relation to age, gender and side. This study was performed as a retrospective analysis on digital panoramic radiographs of 600 (271 males and 329 females) Italian patients between 6 and 87 years old. The styloid process length were measured using the measuring tool of Sidexis Software. It was measured from the point where it left the temporal bone plate to its tip. Styloid processes measuring more than 30 mm were considered elongated. Chi-squared and Fisher tests were used and the test is considered significant if the p-value is lower or equal to 0.05. Thirty-three per cent of the patients showed an elongated styloid process. Seventeen per cent were elongated on both right and left side, fifteen point nine per cent were elongated only in one side. The prevalence of elongated styloid process was high and a progressive increase of the elongation prevalence was found in older groups

The Effect of Different Archwires on Initial Orthodontic Pain Perception: A Prospective Controlled Cohort Study

The early stages of orthodontic treatment are frequently associated with pain that can vary in intensity and duration, representing one of the main reasons for treatment discontinuation. Whilst the use of drugs is recognised as being effective to control orthodontic pain, there are no reliable data indicating the best first archwire for efficacy and minimum discomfort. A prospective controlled cohort study was conducted to compare the intensity and the characteristics of orthodontic pain during the first 15 days of treatment with 2 archwires. Fifty subjects were enrolled and divided into two groups: one received 0.012 inch stainless steel (SS) as the first archwire; the other, a 0.014 inch super-elastic nickel–titanium (Ni-Ti) archwire. Patients compiled a visual analogue scale to measure pain intensity over 15 days, a questionnaire for pain characteristics, the Somatosensory Amplification Scale and the State-Trait Anxiety Inventory to control the psychosocial component of pain. Dental casts were digitally analysed to evaluate the initial arch length discrepancy. In the first 3 days of treatment, the mean VAS values of the SS group were significantly lower than those of the Ni-Ti group (p < 0.05). No significant differences emerged between the groups concerning pain characteristics. The 0.012 inch SS archwire could be used at the beginning of orthodontic treatment to minimise pain perception and improve compliance

The Effect of Bite Raise on AHI Values in Adult Patients Affected by OSA: A Systematic Review with Meta-Regression

Obstructive sleep apnea (OSA) is a highly prevalent sleep breathing disorder characterized by the collapse of the pharyngeal walls that entails recurrent episodes of cessation of breathing or decrease in airflow while sleeping. This results in sleep fragmentation, decreased oxygen saturation and an increase in the partial pressure of carbon dioxide, causing excessive daytime sleepiness, hypertension and increased prevalence of cardiovascular morbidity and mortality. Mandibular advancement devices (MAD) represent a valid alternative therapy to Continuous Positive Airway Pressure, thrusting the mandible forward, increasing the lateral diameter of the pharynx and reducing the collapsibility of the airway. Several investigations have focused on the detection of the best mandibular advancement amount in terms of effectiveness and tolerance, but few and contrasting data are available on the role of occlusal bite raise in reducing the apnea/hypopnea index (AHI). The aim of this systematic review with meta-regression analysis was to investigate the effect of the bite raise of MAD on AHI values in adult patients affected by OSA. An electronic search was performed in MEDLINE, the Cochrane Database, Scopus, Web of Science and LILACS. Randomized controlled trials (RCT) investigating the effectiveness of MAD in OSA patients were included. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) and the risk of bias with the Cochrane risk-of-bias tool for randomized trials (RoB2). Six RCT were included. The success rate of each study was computed: (mean baseline AHI − mean post treatment AHI)/mean baseline AHI. The GRADE scores indicated that the quality of evidence was very low. The meta-regression analysis showed that there was no correlation between the occlusal bite raise and the AHI improvement
