ABSTRACT
Objectives: prefabricated functional appliances have therapeutic effects similar to those of custom-made functional appliances. This study aimed to assess the dentoskeletal effects of Multi P[registered sign] prefabricated functional appliance on Class II Div 1children in late mixed dentition
Methods: this open label trial was conducted on 18 children aged 9-12 years with Cl II Div 1 malocclusion due to mandibular deficiency during a 9-month period. Written informed consent was obtained from the parents. Multi P[registered sign] [RMO, Strasbourg, France] was used by the patients 4 hours/day and overnight [minimum of 8 hours] in conjunction with specific exercises [pressing the teeth in the recorded occlusion, pressing the tongue against the palate and uninostril breathing]. Patients were visited monthly. Study casts and cephalometric radiographs were obtained before and after the treatment. Data were analyzed using paired samples t-test and McNemar's test
Results: the Go-Gn [P=0.029] and Me-N [P=0.021] distances significantly increased following the use of appliance while overjet [P<0.0001], absolute overbite [P=0.002] and the Wits appraisal [P=0.019] significantly decreased. Other understudy angles did not change significantly
Conclusion: multi P[registered sign] appliance decreases the jaw base discrepancy and corrects the overjet and overbite
ABSTRACT
Epidermolysis bullosa [EB] is a group of rare inherited skin and mucous membrane disorders in which blister formation may arise spontaneously or following a minor friction. Various patterns of inheritance are explicated for the disease. The disease has a profound effect on oral mucosa and may result in high prevalence of dental caries. General anesthesia is sometimes the only choice for dental treatments in patients with EB. The following case report describes the dental and anesthetic management of an 12.5 -year-old girl with dystrophic type of EB. The patient was followed up every 6 months. New carious lesions were detected one year after the treatment, on the last visit. Presenting a perfect dental care to children with this disorder can be challenging for the in charge specialist, both pediatric dentist and anesthesiologist
ABSTRACT
The aim of this trial was to compare clinical and radiographic success rates of direct pulp capping [DPC] using a novel biomaterial called Calcium Enriched Mixture [CEM] cement versus Mineral Trioxide Aggregate [MTA] in primary molar teeth. In this randomized clinical trial 42 deciduous molars in 21 patients who had at least two teeth requiring DPC, were treated. The enrolled patients were between 5-8 years. The molar teeth were randomly divided into two experimental groups. Patients and operators were blinded. The teeth were anaesthetized, caries were removed and after pinpoint exposure of dental pulp, haemostasis was achieved. The exposure points were capped with MTA or CEM cement. All teeth were restored with amalgam. Patients were recalled for the 6-month follow up. Statistical analysis was carried out using McNemar test. Thirty-eight teeth were available for follow up [19 in each group]. The radiographic evaluations did not show failure in experimental groups; however, in clinical examinations one sinus tract was found in CEM cement group. Clinical success rates in CEM cement and MTA groups were 94.8% and 100%, respectively. Dentinal bridge formation was not observed in the two experimental groups. There is no significant difference between treatment outcomes of direct pulp capping with either CEM cement or MTA; therefore, both biomaterials can be used successfully for DPC in primary molar teeth
