Abstract:
Anchorage is an important factor in orthodontics and must be properly managed for a successful treatment outcome. Orthodontists have historically used many devices to prevent unwanted tooth movement. The use of miniscrews as a source of skeletal anchorage has become routine in present-day orthodontic practice. Skeletal anchorage opens up alternative treatments, to borderline surgery patients for example, who can now be treated by taking advantage of the biomechanical properties of miniscrews. Because they are bone-borne and provide excellent control over tooth movement in the three spatial planes of movement, mini-implants can be used to serve many purposes in addition to anchorage. Therefore, a variety of successful mini-implant appliances are explained in relation to the three planes of movement: sagittal, vertical, and transverse. The aim of this review is to illustrate the clinical versatility of miniscrews in the three spatial planes of malocclusion in orthodontic and orthopedic management and to define clinical guidelines for the selection, application and biomechanics of mini-implants.

Abstract: INTRODUCTION: Plaque control is the major consensus during orthodontic treatment to prevent the occurrence of cavities and periodontal inflammation. The mechanic resource of greater effectiveness and frequent use in this control is the oral hygiene. The tooth brushing techniques most used in orthodontic patients are: Ramfjord's method, Modified Stillman technique and Bass method. OBJECTIVE: Since control studies evaluating the effectiveness of usual tooth brushing techniques do not show clear advantage, the objective of this study was to evaluate the effectiveness of three brushing methods, through periodontal clinical parameters of patients with fixed orthodontic appliances. METHODS: Thirty patients were selected, with ages between 14 and 22 years old, with fixed orthodontic appliances. After basic periodontal treatment the following factors were evaluated: 1 - Plaque index and 2 - Gingival index and each patient was randomly included in one of the three selected groups according to the brushing technique: Group 1 - Scrubbing technique; Group 2 - Modified Stillman technique and Group 3 - Bass technique. Patients were evaluated for 9 months. RESULTS: The results showed a significant reduction of clinical parameters by the end of this period, however there was a very significant reduction of Gingival index on group 3 (13.6%) when compared to the other groups. CONCLUSION: Thus, it can be suggested that the Bass technique can be effective on the reduction of periodontal clinical parameters of Plaque index and Gingival index in patients with fixed orthodontic appliances. INTRODU O: o controle de placa bacteriana é o maior consenso durante o tratamento ortod ntico para prevenir a ocorrência de cáries e inflama o periodontal. O recurso mecanico de maior efetividade e uso frequente nesse controle é a higieniza o bucal. As técnicas de escova o dentária mais usadas por pacientes ortod nticos s o: a friccional giratória de Ramfjord, a Stillman modificada e a sulcular de Bass. OBJETIVO: tendo em vista que estudos de controle avaliando a efetividade das técnicas de escova o mais comuns n o demonstraram nenhuma superioridade clara, o objetivo desse estudo foi avaliar a efetividade de três técnicas de escova o, através dos parametros clínicos periodontais de pacientes portadores de aparelhos ortod nticos fixos. MéTODOS: foram selecionados 30 pacientes, com idades entre 14 e 22 anos, portadores de aparelhos ortod nticos fixos. Após o final do tratamento periodontal básico, determinou-se o (1) índice de Placa e o (2) índice Gengival, e cada paciente foi incluído,
Thermoplastic retention appliances. A controversial clinical reality.

Hellenic Orthodontic Review , 2011,
Abstract: AIM: The present article attempts to critically analyze the efficiency, advantages and disadvantages of thermoplastic appliances, which are widely used today to retain the outcome of an orthodontic treatment.METHOD: Collection and evaluation of original articles regarding the subject under investigation from PubMed and Cochrane Databases until January 2010.FINDINGS: Transparent appliances are the preferred appliances to retain the orthodontic treatment outcome both by patients and clinicians. They are efficient, esthetically pleasing, provide comfort and have low cost. Despite their tendency to develop open bite and unwanted occlusal contacts, the partial or continuous application and the duration of use don’t seem to comprise destabilizing elements of the treatment outcome compared to Hawley appliances.CONCLUSION: The efficiency combined with the advantages and disadvantages make the thermoplastic appliances an alternative choice to Hawley orthodontic appliances. However, evidence based research needs to establish the advantages of these retention appliances compared to other retention appliances.

Abstract: Nigeria has since integrated EE concepts into all subjects at the primary and secondary levels of education. However, the major dilemma faced by Nigerian teachers is how to effectively teach these concepts to develop appropriate environment-related attitudes and values in the learners. Most classrooms in Nigeria are still characterized by teacher dominated strategies which may not be able to foster appropriate environmental attitudes. This study therefore explored the use of participatory learning strategies in teaching environmental education concepts. The study further examined the interactive influence of group size and academic ability of students on the dependent measures. The assumption for trying these strategies was based on the premise that EE is not just about telling, but about knowing and acting. Three hundred and sixty Senior Secondary II students drawn from nine schools constituted the subjects for the study. The students were taught the selected EE concepts using the full and quasi-participatory strategies with the conventional lecture as the control. The Environmental Attitude Questionnaire constituted the only instrument used for data collection. Four hypotheses were tested at p<0.05 level of significance. Findings from the study show that students taught EE concepts using the participatory approaches developed a more positive attitude to the environment, with those in the full participatory group having the best attitude scores. The results also indicate that students who worked in the small groups demonstrated a more favourable attitude. The participatory approach affords the students to learn and work more effectively with others which made them more sensitive to the necessity of having a descent respect for the opinions of others and be more sensitive to their environment. The implications of these findings for the teaching of EE concepts were discussed. On the whole, it was suggested that the participatory group learning strategies could be a more viable alternative to the traditional conventional methods of classroom teaching.

Abstract: Background/Aim. Orthodontic treatment enables the establishment of functional occlusion and improvement of oral health, however, it increases the risk of periodontal disease development. The aim of this paper was to examine the efficiency of the applied programme for the prevention of gingivitis in children undergoing the fixed orthodontic appliance therapy and to determine the most efficient devices and techniques for maintaining oral hygiene during orthodontic treatment. Methods. The study included 80 patients of both genders - 60 patients comprised the experimental group and 20 patients comprised the control group. All of them were patients of the Clinic for Orthodontics at the School of Dentistry in Belgrade, aged between 13 and 18. The Silness-L e Plaque Index (PI) was utilised for the assessment of oral hygiene quality and Silness-L e Gingival Index (GI) and Mühlemann Papilla Bleeding Index (PBI) were utilised for the assessment of gingival state. Checkups were conducted as a single-blind study at the beginning and after the first, the third and the sixth month of the preventive and prophylactic programme. Results. During the observed period, a statistically significant change in PI, GI and PBI values was noticed (p < 0.005), as well as the difference in the dynamics of value changes during the periods between the observed groups. Conclusion. The preventive programme, applied to children undergoing the fixed orthodontic appliance therapy, had a positive effect both on oral hygiene quality and gingival state. The values of the examined parameters of the patients from the experimental group were significantly lower in comparison with those of the patients from the control group. The most efficient combination of devices for oral hygiene during orthodontic treatment was: a Curaprox CP5460 toothbrush, CD Ortho 60 orthodontic toothbrush and Curaprox CPS 14 interdental brush.

Abstract: During the last 10 years numerous investigations using saliva as a diagnostic tool have been carried out. The aim of present study is to evaluate saliva qualities for various general diseases and conditions that influence its qualities. (1) Evaluation of salivary flow and saliva consistency of children. (2) Evaluation of saliva pH and buffer capacity of children. Material and Methods. The investigation was carried out with 126 children (age 6 to 17) selected by their general diseases and conditions influencing the oral risk environment. The children were divided into 4 groups: 30 children with diabetes, 25 children with asthma treated with local corticosteroids, 27 healthy children with orthodontic treatment, 34 children as a control group (healthy children). The saliva of the children was tested with the help of “Saliva Check” of GC company. The instructions of the company producer were followed.Results. Stimulated saliva current is reliably lower for children with asthma treated with local corticosteroids, diabetes and children with orthodontic appliances. Saliva pH is with lower values for children with diabetes and asthma – diseases predisposing to acid oral environment. The decreased saliva buffer capacity for children with diabetes and asthma is an indicator for the difficult regulation of the dynamically changing oral electrolytic balance of those children.Conclusion. The saliva parameters studied can be used as biomarkers of the liquid oral environment with regard to the risks for caries and periodontal diseases in children. General health status influences saliva qualities increasing thus indirectly the caries risk.
