This article discusses the use of the DamonTM Passive-Self Ligating system in the functional treatment of Angle Class II/2 malocclusion. The study presents a case study of an 11-year-old female with this malocclusion and demonstrates the effectiveness of the DamonTM system in achieving anteroposterior correction without the need for fixed Class II appliances. The treatment involved strategic wire transitions, bracket repositioning, and meticulous occlusal assessments. The article emphasizes the importance of proper torque selection and the use of light elastics for gentle treatment. The document also discusses the use of the PSBL Damon Q2 system in orthodontic treatment for individuals with Class II division 2 malocclusion, highlighting its ability to control and improve arches and buccal corridors, as well as the inclination of incisors and anterior guidance. It also mentions the effectiveness of the Damon Q2 PSL in addressing crowding and achieving a natural arch form without the need for extractions or specific Class II correctors.

The objective of our study was to evaluate in vitro the cytotoxicity of different intraoral elastic chains and elastomeric ligatures that are used as components of orthodontic fixed appliances. The study evaluated the reaction of tree groups: the negative control group (human fibroblasts cultures), the positive control group (dental copper amalgam) and the study group represented by intraoral orthodontic elastics: elastic chain (Orthoclassic) and elastomeric ligatures of different colors and latex consistency from different manufacturers (Orthoclassic and GAC). After 3 and respective 6 days we analyzed the samples by direct method and microscopic analysis (Nikon Eclipse TE300). We analyzed the shape of the fibroblasts around the material, their number and the morphologic alterations of the cells. The analysis of the fibroblasts situated at distance from the material and the percent of the vital cells was obtained by comparing the maxim cells density of the negative control group with the density of the study groups. The dental copper amalgam determined the apoptosis of all the cells of the group and showed a high cytotoxicity. The elastic chain Orhoclassic determined important morphologic changes on human fibroblasts cultures and showed a reduced biocompatibility. The elastomeric ligatures Orthoclassic with low elasticity showed a relative biocompatibility. The elastomeric ligatures Orthoclassic with high elasticity showed a good biocompatibility. The elastomeric ligatures GAC showed a relative compatibility at 3 days but a high cytotoxicity at 6 days.

This article explores the impact of mouth breathing on the development of the dento-maxilo-facial complex in children and adolescents. It discusses the effects of mouth breathing on occlusion and muscle development, emphasizing the importance of early identification and intervention. The article highlights the association between mouth breathing and malocclusions, as well as other morphological alterations in the maxillofacial complex. It also discusses the increased risk of dental caries and the importance of early diagnosis and intervention by dental professionals. The document is a list of references related to the topic, providing a comprehensive overview of the factors and consequences associated with mouth breathing in children.

This article from the Romanian Journal of Oral Rehabilitation discusses the dental anomaly known as taurodontism and its challenges in pediatric dentistry. Taurodontism is characterized by an enlarged pulp chamber and a lack of constriction at the cement-enamel junction. It can appear as an isolated anomaly or be associated with syndromes and abnormalities. The article highlights the difficulties in endodontic treatment and emphasizes the need for clinicians to review the best treatment options for taurodontic teeth. The text discusses the challenges and management of taurodontic teeth, which have unique anatomical variations. The root canal system of taurodontic teeth can be complex and difficult to access. The treatment may involve careful exploration, magnification, and ultrasonic irrigation. Extraction of taurodontic teeth can be complicated due to the dilated apical third, but it may also be easier due to the large body and small surface area. Taurodontic teeth may have favorable periodontal prognosis in certain cases. Prosthodontic treatment should avoid post placement and consider the strength of the tooth. Taurodontism can also be associated with genetic syndromes and systemic conditions. Dental practitioners should be aware of these changes and use appropriate techniques for endodontic and prosthodontic management. [Extracted from the article]

The aim of the study was to evaluate, by means of a questionnaire, students' opinions on the practice and orthodontic curriculum, the methods of assessing knowledge, as well as the final marks obtained, in order to appreciate the efficiency of the orthodontic university education. The study was conducted on 273 students, aged 23-35 years, from the public Faculty of Dental Medicine in Iasi, Romania. Anonymous questionnaire consisted of 16 items with multiple answers. Students’ knowledge was evaluated during final exams. Statistical analysis was performed with SPSS 16.0. Students' opinions were positive. Significant correlations between answers according to gender and study years were found (p<0.05). The average final marks earned by the students of the 6th year were higher than of those of the 5th year. The study demonstrates that the standard of undergraduate orthodontic education is quantified according to students’ results, but the teachers must take into account their opinions, for improving the teaching-learning process.

This study performs a clinical, radiological and statistical evaluation of permanent teeth impaction on a sample of young patients from the North-eastern region of Romania. 67 orthodontic patients (29 boys and 38 girls), aged 6-37 years, were selected randomly during 1991-2010. Data from orthodontic records were evaluated according to social parameters, oral status, etiological causes, clinical features and treatment options. Statistical evaluation was done with the SPSS 20.0 package. The cuspid impaction was most frequent in girls (68.40%) and in boys was the central incisor impaction (55.20%). The most common was the single tooth impaction in upper arch (85.10%) and the severe impaction (76.10%). We found statistically correlations between the direction and localization of impaction and types of impacted teeth (p=0.002). 4.14:1 ratio was established between the conservative and the radical treatment. The risk factors (OR=1-5) and predictors for the extraction of impacted teeth (HL test, p=0.000) were identified. [ABSTRACT FROM AUTHOR]
