RISK FACTORS IN THE EFFECTIVENESS OF ORTHODONTIC TREATMENT IN MIXED DENTITION

In this longitudinal study we evaluated the risk factors for the effectiveness of orthodontic treatment in mixed dentition on a sample of 110 patients (52 boys and 58 girls) aged 6 to 10 years in northeastern Romania in the active phases of orthodontic treatment. 13.6% of patients were quitted the treatment or did not come to scheduled appointments. Initially, removable functional appliances were used in 54.7% of patients and myofunctional activators in 45.3% of patients. After evaluating the 6-month treatment results (good in 64.7% patients and poor in 64.7% patients), the appliances were changed according to patient compliance and dental hygiene status. The treatment outcomes after 12 months were good in 78% of patients and decreased in 22% of patients. The effectiveness of orthodontic treatment in mixed dentition has depended both on parents' understanding of the need for treatment, but also on patient co-operation and compliance

ASSESSMENT OF SCHOOLCHILDRENS’ KNOWLEDGE, ATTITUDES AND BEHAVIORS FOR ORAL HEALTH

Aim of the study was to assess the level of knowledge of oral and nutrition hygiene measures for dental caries, malocclusions, periodontal disease, outbreak prophylaxis and self-assessment of oral health and social impact as well as the role of the dentist. Material and methods. The study was conducted on 166 schoolchildren aged 7-18 years (mean age 14.51±3.312 years), from four public schools in Neamt County, north-eastern Romania, who responded independently to an oral health questionnaire. Statistical analysis was performed with SPSS 16.0 (SPSS Inc., Chicago, IL) for Windows, and descriptive statistics and Pearson chi-square test were used. Results. The results fluctuated according to the correct answers to the questions. The overall score of the schoolchildren’ correct answers was 71.00%. Significant correlations between age and school of children and certain answers to questions were found (p<0.05). Conclusions. The study demonstrates that school cannot alone induce desirable health behaviours and requires the involvement of many specialists, family and communities by implementing effective education programs recommended by the World Health Organization

INTERDISCIPLINARY APPROACH IN THE TREATMENT OF CONGENITALLY MISSING LATERAL INCISOR

In dentistry treatment of difficult cases may be accomplished using an interdisciplinary approach. This article describes the orthodontic treatment in a female patient (12-years old) which was diagnosed with congenitally missing of upper left lateral incisor and Angle’s Class III malocclusion. The treatment plan was interdisciplinary using preprosthetic orthodontic treatment for facilitate the surgical, implant and restorative treatment. The treatment were favorable, fulfilled the patient expectation and improving facial esthetics and restoring the functions. This case demonstrates that an interdisciplinary team (orthodontist, dental surgeon, prosthodontist) is required for the successful treatment of the congenitally missing of lateral incisor to create ideal conditions for the insertion of the dental implant

IMPACTION OF A CENTRAL MAXILLARY INCISOR DUE TO SUPERNUMERARY TEETH. COMBINED ORTHODONTIC AND SURGICAL TREATMENT

Impaction of a maxillary central incisor is a rare dental condition which is easy noticed by the patient and the general practitioners because it has a strong impact against dental and facial esthetics. In many cases this is due to the presence of one or more supernumerary teeth, easy recognized on radiographs. The absolute indication in these situations is the early removal of the supernumerary teeth in order to minimalize the damage in the anterior area. Almost in all cases the surgical phase should be followed by the orthodontic phase in order to bring the impacted tooth in the dental alignment, to establish the proper occlusion and function. In our paper we present the case of a 9 years boy with left central maxillary incisor impaction and 2 supernumerary teeth in the anterior area. The case is presented step by step until the final result at the end of the treatment with the upper incisor in plac

ASSESSMENT OF PATIENT ANXIETY BEFORE DENTAL TREATMENT

Aim of the study was to identify the prevalence of patient anxiety before treatment and to determine patients’ perception of the dental treatment risks. Material and methods. The cross-sectional study was conducted in 210 patients (69 males and 141 females) aged 11-70 years in northeastern Romania, who completed Corah’s Dental Anxiety Scale, Revised (DAS-R), Modified Dental Anxiety Scale (MDAS) and Dental Concerns Assessment, Revised (DCA-R). Results. The overall scores of DAS-R indicated high anxiety in 4.3% of patients and severe anxiety or phobia in 2.9% of patients. Overall scores of the MDAS questionnaire indicated 5.2% of very anxious patients and 2.3% of highly anxious or phobic patients with dental treatments. DCA-R indicated high anxiety for injection and extraction. We found statistically significant differences between anxiety levels and age ranges as well as patients’ environmental areas (p<0.05). Conclusions. Anxiety to dental practice can affect the quality of treatment and is a serious reason to avoid the dentist office

MAXILLARY FIRST MOLAR DISTALIZATION WITH THE FROG APPLIANCE A CASE REPORT

Traditional upper molar distalization techniques require patient co-operation with the headgear or elastics. Recently, several different intraoral procedures have been introduced to minimize the need for patient cooperation. Distalizing maxillary first molars is often an objectiv in treatment plans inolving Class II malocclusions and is sometimes indicate for non-extraction treatments with maxillary crowding. Pacient compliance has become a factor in choosing effective orthodontic appliances. In recent years various appliances that do not require patient compliance have been developed to drive maxillary molars distally. Some of these appliances produce unwanted tipping of the maxillary molars and a tendency to create crossbites if not properly adjusted. Therefore we want to present a case that presented in the clinic of Orthodontics and dento-facial orthopedics in the Ambulatory Pediatric Dentistry in Iasi. L.S. patient aged 12 years presenting for aesthetic and functional disorders. On examination extraoral facial changes occur hyperdivergent profile. Clinical examination reveals intraoral Angle Class I molar malocclusion, anterior deep bite, mesial inclination of the lower left permanent molar. Upper canines teeth are erupting bucally, due to lack of space. OPT examination and anamnesis reveled reduction the space for the lower left second premolar and for the lower right canin probabily due to premature loss of second primary molar and primary canine. Indicate a slight lateral cephalometric skeletal Class II (∠ ANB inv. = 5.040) with a hyperdivergent profile ∠GoGn/SN=360 .We wanted a non extraction treatment except the 3rd molars.. The treatment plan included distalization of the upper first molars bilaterally followed by a palatal expander and a full fixed appliance therapy. For the lower arch we applied a lip-bumper for moderate arch expansion and for lower molars distalization. For the upper molar distalization, a new system, the Frog Appliance, was constructed and applied. Lateral cephalometric radiographs were used to evaluate the treatment results. It was obtained an over distalization of the first molars after 10 mouths of treament because the patient missed the subsequent checks. The lower lip-bumper was not carried. According to the results of the cephalometric evaluation, a nearly bodily distal molar movement was attained. It was reapplied lip bumper and a palatal expander. The patient is still in treatment. In conclusion, the Frog Appliance was found to be effective, non-invasiv appliance for achieving bilateral molar distalization, but the patients should be more motivated to come to check up

THE FUNCTIONAL TREATMENT OF ANGLE CLASS II/2 MALOCCLUSION USING DAMONTM PASSIVE-SELF LIGATING SYSTEM

Class II division 2 malocclusion, associated with mandibular retrognathia, presents distinct dental features and potential temporomandibular joint implications. Orthodontic interventions, particularly fixed appliance treatment, may lead to adaptive condyle reconstruction and establish a more suitable spatial relationship for the mandible. A case study of an 11-year-old female with Class II division 2 malocclusion illustrates DamonTM Passive Self-Ligating system efficiency and effectiveness. Anteroposterior correction was achieved with light elastics, eliminating the need for fixed Class II appliances and mitigating potential iatrogenic effects. Treatment progression involved strategic wire transitions, bracket repositioning, and meticulous occlusal assessments

Measurement of the Clinical Effects of a Marine Fish Extract on Periodontal Healing—A Preliminary Clinical Interventional Study

The aim of the study was to assess the clinical effects of periodontal healing using a Romanian pharmaceutical compound of marine fish extract (Alflutop®). Adults with periodontal disease were included in the study group. Gingival inflammation, the degree of tooth mobility, and probing depth (PD) were recorded for each patient before and after therapy. Patients were divided into two groups: group I—after scaling and root planing (SRP), patients followed therapy with marine fish extract, Alflutop®, group II—SRP therapy alone. Statistically significant differences between groups in terms of gingival inflammation reduction (p = 0.045) were found. Tooth mobility reduction, as well as PD improvement, were also noticed after the therapy (p = 0.001), but no statistically significant differences among PD reduction rates were found (p = 0.356). Alflutop® has proven a certain therapeutic efficiency in the treatment of periodontitis in terms of reduction in the clinical signs of inflammation and tooth mobility

In-Vitro Analysis of FeMn-Si Smart Biodegradable Alloy

Special materials are required in many applications to fulfill specific medical or industrial necessities. Biodegradable metallic materials present many attractive properties, especially mechanical ones correlated with good biocompatibility with vivant bodies. A biodegradable iron-based material was realized through electric arc-melting and induction furnace homogenization. The new chemical composition obtained presented a special property named SME (shape memory effect) based on the martensite transformation. Preliminary results about this special biodegradable material with a new chemical composition were realized for the chemical composition and structural and thermal characterization. Corrosion resistance was evaluated in Ringer&rsquo;s solution through immersion tests for 1, 3, and 7 days, the solution pH was measured in time for 3 days with values for each minute, and electro-corrosion was measured using a potentiostat and a three electrode cell. The mass loss of the samples during immersion and electro-corrosion was evaluated and the surface condition was studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). SME was highlighted with differential scanning calorimetry (DSC). The results confirm the possibility of a memory effect of the materials in the wrought case and a generalized corrosion (Tafel and cyclic potentiometry and EIS) with the formation of iron oxides and a corrosion rate favorable for applications that require a longer implantation period
