    The aim of this study was to find out how many of the orthodontic patients had problems with the support area and if these could be identified and treated before any complications could occur; and also how the eruption process in the support area is influenced by these modifications. Materials and Methods: In this study, 62 patients, 34 girls (mean age: 10.03 years), and 28 boys (mean age: 9.67 years) were sampled from those who were prepared for treatment at the Orthodontic Department. Their panormaic radiographs were analyzed, especially the support area and the sequence of eruption of canine and bicuspids. Results: 56% of female and 43% of male subjects had an intact support area, while the rest showed modifications. 61% from patients with a good support area showed a normal sequence of eruption. However, when the second group was analyzed, 90% of them presented a modified sequence of eruption. In the first group in 84% of situations, even the second molar erupted normally, but, in the second group, 68% of the patients showed a modified sequence. Conclusion: Half of the investigated subjects showed some modifications in the support area. The number of male subjects with this situation is higher than that of the female subjects. When the support area develops normally, the sequence of eruption of permanent teeth is not modified, but, in those subjects who showed a changed support area, even the sequence of eruption was changed. In the same way, we can conclude about the sequence of eruption of the second molar: if the support area is normal, it will erupt after the second premolar; but if otherwise, some changes will occur in the process of eruption

    The aim of this study is to evaluate teeth discoloration after the usage of adhesive fluoride release. Material and Method: 80 extracted healthy premolars divided into two groups were used in the study, with metal brackets being bonded in both groups,. The first group universal adhesive was applied (transbond light cure adhesive paste-Transbond XT), whereas in the second group fluoride releasing bonding material was used (opal bond MV composite and opal seal). The measurement of color parameters was performed using the spectrophotometer vita easyshade 4.0 to calculate ΔL, Δa, Δb, and ΔE. Statistical Analysis: 3-way mixed analysis of variances (ANOVA) was used to compare ΔE before using adhesive material and after the procedure. On the other hand, it was used to compare Δa, Δb, and ΔL before and after using adhesive material. The statistical significance level was established at P< 0.05. Boferroni correction was used to create mean differences between the results. Results: The result of this study showed that ΔE* values were increased in all groups. The mean difference of ΔE* value in the first group (3M adhesive material) was 2.54± 1.57. At the same time, the ΔE value in opal adhesive group was 4.43±5.4. These results showed that fluoride seal had direct effect on enamel color after a period of three months teeth storage. Results showed above the normal limit and produced visible color change on the surface of the teeth after finishing procedure. On the other hand, ΔL values were increased in both groups, with a significant difference in the first group (p value 0.04) and with no significant difference in the second group (p value 0.239). Conclusion: The highest color changes were observed after the finishing procedure in opal bond MV composites and the opal seal groups. This was done by increasing ΔE value due to the presence of fluoride release adhesive structure. Transbond light cure adhesive past-Transbond XT had acceptable clinical change after the debonding and finishing procedure by increasing ΔE value

    Dental-maxillary anomalies are accompanied by changes in the interbasal maxillary ratio in all reference planes, with influences on the functionality of articular structures. These joint changes not detected in time and not included in the treatment plan may worsen while wearing fixed appliances, as orthodontic treatment changes the cranio-mandibular position and causes cranio-mandibular reshaping. The articulator is an instrument that reproduces more or less all mandible movements. TMJ characteristics of skeletal dento-maxillary anomalies, especially class II sagittal pattern mainly reflected in condylar position rather than morphology. TMJ of different vertical patterns differed more in joint spaces, position of condyle and glenoid fossa than in morphologic measurements. Vertical position of glenoid fossa and proportion of posterior condyle increased gradually from hypodivergent to hyperdivergent. Highest glenoid fossa position, maximum ratio of posterior positioned condyle, smallest joint spaces, shallowest glenoid fossa depth, and narrowest condylar long axis diameter were found in skeletal class. The patients with high angle have considerable joint instable factors, and we should especially pay attention when orthodontic treatment is carried out on them. The condyle-fossa position and morphology differ with various vertical facial patterns in individuals with skeletal Class II mandibular retrognathism. These differences could be considered during temporo-mandibular diagnosis and orthodontic treatment

    DENTAL AGE ASSESSMENT USING DEMIRJIAN’S METHOD – A RADIOGRAPHIC STUDY

    Get PDF
    Dental age estimation on panoramic X-rays is very useful for pediatric dentists and orthodontists in choosing a treatment plan, without the need for any additional radiographic investigation. The aim of this study was to compare chronological and dental age using Demirjian’s method on children from Central Romania. The study was conducted on X-rays of 285 children aged between 6-13 years. Dental age was determined based on the degree of mineralisation of the seven left mandibular teeth, and t-tests were used to assess the difference between dental age and chronological age within each age category. Dental age was more advanced in girls in almost all age groups, whereas in boys just the 6-7 and 8-9 age groups presented a more advanced dental age. The results of our study show that Demirjian’s method has some limitations for a Romanian population, and that these standards are applicable only in certain age groups. Further research is required on a larger sample

    The aim of the study: Corticotomy-facilitated orthodontics is a modern approach to resolve complicated orthodontic cases that may increase the pace of tooth movement. The study's goal was to assess the changes that occurred at the root level following orthodontic treatment when corticotomy was used. Material and methods: Based on Cone Beam Computer Tomography, measurements of the root length at T0 (before corticotomy) and T1 (after corticotomy) were taken after splitting the individuals into two groups (maxillary and mandibular corticotomy) (6 months after surgery). For statistical analysis of the data, many tests were utilized. Results: The root length values obtained at T1 showed minimal changes in length, with statistically insignificant values (for the maxillary arch, the values obtained were 13.36 ± 2.41 mm for women and 14.26 ± 2.06 mm for men; for the lower arch, the measured values were 12.38 ± 2.09 mm for women and 11.56 ± 2.29 mm for men). The canine on the left hemiarcade had the most significant change in root length following treatment, with a value assessed at T1 of 16.72 ± 1.78 mm, which was statistically significant, p 0.05. Conclusion: According to the data obtained in this study, when orthodontic therapy is associated with corticotomy, there is a decrease in root resorption that may occur in the case of conventional orthodontic treatments

    The aim of the study was to assess the preventive and therapeutic efficacy of a sustained-release varnish (SRI) Cervitec Plus compared with Corsodyl (R) mouthwash against Candida albicans, Candida parapsilosis, Candida tropicalis and Candida glabrata on acrylate surfaces. Nystatin as the positive control, and sterile saline solution as the negative control, were used. To examine the preventive efficacy of the agents, Candida biofilms were developed in Sabouraud liquid medium, and mature biofilms were treated with the antifungal. To investigate the preventive efficacy, the agents were applied to the wells of the plates and the biofilms were grown in the treated wells. To determine the metabolic activity of biofilms, the XTT-assay was used. In the case of C. albicans and C. parapsilosis, the most effective therapeutic product was Corsodyl (R) followed by Cervitec Plus (R) and Nystatin. The differences were statistically significant when Corsodyl (R) was compared to Nystatin (p <= 0.05). In relation to C. tropicalis and C. glabrata, Corsodyl (R) showed the greatest therapeutic efficacy followed by Nystatin and Cervitec Plus. For both species, the results of Corsodyl" and Cervitec Plus (R) showed statistically significant difference (p <= 0.05). The most effective preventive product for each examined Candida species was Nystatin, followed by Cervitec Plus and Corsodyl (R). Significant differences were between Nystatin and Corsodyl (R) (p <= 0.05). The preventive and therapeutic efficacy of Cervitec Plus and Corsodyl (R), against the examined Candida species, was detected. Because of the disadvantageous side-effects of Nystatin, Cervitec Plus can be considered as an alternative preventive agent against Candida species

    Both dental caries and malnutrition in children are serious public health problems with diet as a common risk factor. The aim of this study is to investigate the relationship between dental caries, Body Mass Index (BMI) and salivary buffer capacity in children. Materials and Method: The first part of the study was conducted on 144 children, aged between 6 and 12 years, examined in the Pediatric Dentistry Department of UMF Tirgu Mures. Nutritional status was assessed using BMI in accordance with the recommendations of the World Health Organisation. The sample was divided into four groups based on BMI: underweight, normal weight, overweight and obese for age. Dental caries were evaluated using the DMFT (Decayed Missing Filled Teeth) index for permanent dentition and dmft (decayed missing filled teeth) for deciduous dentition. Salivary buffer capacity was recorded with CRT Buffer Strips from Ivoclar Vivadent. Results: The mean age of the sample was 9.11 ± 0.19 years, the mean dmft was 2.58 ± 0.26 and mean DMFT 1.76 ± 0.2. The underweight group presented a significantly higher dmft index compared to the other groups. A negative correlation between the salivary buffer capacity and the caries index was found. Conclusions: Because the results of this preliminary study show a higher caries incidence in underweight children, the relationship between dental caries and malnutrition should be further investigated. Dentists and physicians treating children should consider malnutrition as a risk factor for dental caries

    Patient’s interest towards interconnection and social implication with trainer doctor model

    Get PDF
    OED and the dictionary of the world defines a "doctor" 700 years ago and today as a "teacher". The root word for the word doctor derives from Latin "docere", which means "to teach". The doctor contributes to educating patients about a number of medical conditions (the patient is experiencing a number of diseases). In essence, the doctor has the role as a teacher. Doctor-patient interaction works on relational models. The physician-trainer paradigm is required to be introduced to improve patient status. The physician-trainer model is a participatory model that results in achieving the patient's well-being and improving his/her health; the physician uses his or her capacity as a trainer, that is, he has the ability to form and instill adequate conduct for each patient. In this paper, besides highlighting the appetence for the relationship between the trainer and the patient, we tried to quantify the patient's acceptance of the treatment with/without continuous monitoring of the disease (chronic diseases), the degree of reasonableness in accepting the therapeutic behavior, and lastly how the individual feels the change of his status in the patient. The study was conducted on a total of 217 subjects (125 female subjects and 92 male subjects). The applied questionnaire contained 18 questions, structured to help us confirm or not the study's objectives. The results obtained will show us the level of appetite for the trainer-patient relationship
