Statistical study concerning doctor’s opinion in using the Diode Laser in Endodontics

Our questionnaire-based study with 14 items proposed an investigation of the dental practitioners' opinions and knowledge of lasers, especially on the diode lasers application in Endodontics. The number of respondents was 104, with a higher percentage of 44.2% between 23-30 years old and 61.5% women. 86.5% of the participants worked in the private dental system. 80.8% of the respondents stated that they do not use the diode laser in their daily practice. Only 43.3% considered diode lasers useful in the sterilization of root canals, and 87.5% of respondents considered the sodium hypochlorite the most effective antiseptic. Among those who do not use laser systems, 76.9% were complaining about the high costs of this equipment. 65.4% of the respondents stated they never used the diode laser during endodontic treatment, and the most frequent use was for sterilizing the infected root canals. 87.5% did not know which wavelength to use in practice. Asked if they would like to learn how to use the laser system, 76.9% (80) of respondents answered affirmatively, and 45.2% of study participants said they wanted to purchase a laser system in the future. There is a great need to educate dentists to use diode lasers and make them aware of their advantages. The only problem at present is the need for more affordable laser equipment

Observational Study Regarding Two Bonding Systems and the Challenges of Their Use in Orthodontics: An In Vitro Evaluation

The purpose of this in vitro study was to analyze and identify a methodology for the improvement of the shear bond strength of orthodontic brackets bonded with two orthodontic adhesive systems considered to be widely used, Transbond Plus Color Change with Transbond Plus Self-Etching Primer and Fuji Ortho LC with orthophosphoric acid under various enamel conditions: dry, moistened with water and moistened with saliva. The sample size included a group of 120 freshly extracted premolars distributed into six study groups, each one of 20 teeth. A universal testing machine was used to detach the brackets. We determined and compared the strength of the two studied adhesive systems used in different enamel surface conditions. The mean shear bond strength values in groups 1 (TPCC, TSEP, dry), 2 (TPCC, TSEP, water), 3 (TPCC, TSEP, saliva), 4 (Fuji Ortho LC, etched, dry enamel), 5 (Fuji Ortho LC, etched enamel, water) and 6 (Fuji Ortho LC, etched enamel, saliva) were 15.86, 12.31, 13.04, 15.27, 14.14 and 13.11 MPa, respectively. ANOVA test and Student’s t-test showed significant differences between groups. While clinically acceptable shear bond strengths were obtained for all six studied groups, a particular outcome that to the authors’ knowledge has not been documented elsewhere has been obtained: in case of water contamination, it is preferable to use Fuji Ortho LC instead of Transbond Plus

METHODS TO REDUCE ANXIETY APPLIED IN THE PEDODONTIC PRACTICE

Aim of the study The aim of the present study is to compare the effects of two relaxation techniques widely used in psychotherapy on anxious child patients. Material and methods We investigated a sample consisting of 56 anxious minor patients with odontal problems. First, we determined children’s anxiety levels by using the questionnaire method and biological parameters measurements. Spielberger’s State-Trait Anxiety Inventory was the questionnaire patients had to fill in and pulse and blood pressure were the measured biological parameters. High anxiety levels demonstrated by our patients were then reduced by using two relaxation techniques both belonging to cognitive-behavioural psychotherapy. We determined and compared the effects of those techniques on children’s anxiety by statistical means. Results Jacobson’s Progressive Relaxation Technique proved to be more effective. It is very useful for the dentist to know and apply relaxation techniques to reduce anxiety which is a common problem in the pedodontic practice

A Brief Review on Micro-Implants and Their Use in Orthodontics and Dentofacial Orthopaedics

The aim of this study was to review the literature and evaluate the failure rates and factors that affect the stability and success of temporary anchorage devices (TADs) used as orthodontic anchorage. Data was collected from electronic databases: MEDLINE database and Google Scholar. Four combinations of term were used as keywords: “micro-implant”, “mini-implant”, “mini-screw”, and “orthodontics”. The following selection criteria were used to select appropriate articles: articles on implants and screws used as orthodontic anchorage, published in English, with both prospective and retrospective clinical and experimental investigations. The search provided 209 abstracts about TADs used as anchorage. After reading and applying the selection criteria, 66 articles were included in the study. The data obtained were divided into two topics: which factors affected TAD success rate and to what degree and in how many articles they were quoted. Clinical factors were divided into three main groups: patient-related, implant related, and management-related factors. Although all articles included in this meta-analysis reported success rates of greater than 80 percent, the factors determining success rates were inconsistent between the studies analyzed and this made conclusions difficult

RADIOGRAPHIC DETERMINATION OF THE DIFFICULTY IN EXTRACTION OF THE THIRD IMPACTED MANDIBULAR MOLARS

Aim of the study: to evaluate a reliable and user-friendly index to predict the surgical difficulty of the extractions of mesioangular impacted mandibular third molars. Material and method: Our retrospective study included 237 patients aged 16 to 40 years, with an average of 27.3. The patients were categorized into three different age groups, under 20 years, between 20 and 30 years, and between 30 and 40 years. Depending on the values of the angle of the long axis of the lower third molar with the axis of the mandibular canal we divided the cases into three groups: the first with an angle of 0°-30°, the second with an angle between 30°-60° and the last with values between 60°-90°. Another studied parameter was the operating time. Results: There were 67 patients under 20 years old (28.3%), 113 between 20 and 30 (47.7%), and (24%) between 30 and 40. 35% of the group were men, while 65% were women. The chi-square test showed a negative correlation between the duration of the surgical intervention and the molar angulation (p=0.049). There was no statistically significant correlation between the duration of the extraction and the age of the patients (p=0.941).Conclusion: Based on the results of our study, we can propose a larger one to confirm the findings of your research

DENTITION CHANGES IN GENETIC DISEASES

This paperwork aims to identify the dentition’s changes in genetic diseases and to find solutions to solve them. Method: We studied 31 patients with different genetic diseases (Down syndrome, Turner syndrome, Prader-Willy syndrome, Bardet-Biel syndrome, Tourette syndrome , Pfeiffer syndrome,and schizophrenia ). The patients were of school age (7-14 years old) and followed socialization programs within a foundation, the study taking place over 1 year). Conclusion: the most frequent cases were represented by dental malocclusion (98,16%), correlated with mental retardation and facial dysmorphism (74,2%), shape and structure anomalies (76,11%), mandibular hypoplasia (33,3%) and 6% pigmentation on the mucous membranes. Conclusions: We believe that the health education of parents with rare genetic diseases that affect skeletal development should be emphasized in order to ensure better oral health in this group. The health system should develop screening strategies and education and support services. Also, access to dental treatments for patients with rare genetic diseases should be supported through various programs

Pain Perception during Orthodontic Treatment with Fixed Appliances

The present study aimed to determine the intensity of pain perception in patients undergoing fixed orthodontic treatment. We analyzed the severity of pain concerning four routine procedures: the placement of separating elastics, ring cementations, arch activations, and elastic tractions. Our study consisted of a sample of 100 patients between 12 and 35 years old during the initial months of orthodontic treatment with fixed appliances. The patients completed a questionnaire meant to assess their pain sensation perception. The study sample was divided according to age and sex. By determining the intensity of pain felt during the four orthodontic procedures, we found that the most painful one was the ring cementation in all four age groups. The therapeutic-arch-activation procedure ranked second, with a higher mean value (2.66) in the 18–24 age group; the least painful was considered the elastic traction procedure, with a higher value (1.33) in the group over 30 years old. The most painful period was during the first 3–4 days after procedures. Most patients showed moderate pain after following the studied orthodontic interventions and required analgesic medication, the most frequently used being Nurofen, ketonal or paracetamol. The level of pain felt was significantly higher in men than in women. Patients suffer differently from the intensity of perceived pain as they grow older

Psychometric Properties of Scared-C Scale in a Romanian Community Sample and Its Future Utility for Dental Practice

The psychological management of children and adolescents in need of pedodontics or orthodontic treatments continues to be an essential objective in dental activity because along with the accuracy of the techniques that are used, anxiety reduction, and knowledge of how to approach the patient are necessary for the treatment to be successful. Therefore, our study aimed to validate the Screen for Child Anxiety Related Emotional Disorders questionnaire, the child version of 41 items (SCARED-C) in the Romanian population for later use in pediatric dentistry. The instrument showed moderate to good internal consistency (α Cronbach from 0.63 to 0.91 for the total scale) and good test–retest reliability (0.70) on a subset of a sample comprising 85 children. A confirmatory factorial analysis (CFA) was conducted to test the factor structure of the Romanian version of the SCARED-C; the results showed that SCARED-C has good psychometric properties that can be used for screening anxiety in Romanian children and adolescents. The implications of using the SCARED-C in dental practice are discussed. Future studies need to be conducted to explore the convergent and discriminative validity of the instrument and its sensitivity to current DSM-V criteria. Application on a pediatric dental sample is also required

FREQUENCY OF THIRD MOLAR PATHOLOGY: INNOVATIVE CAUSES, SYMPTOMS AND TREATMENT OPTIONS

This study aims to present the frequency of pathology at the level of molars of the mind, this pathology can have a multitude of local and general factors, but the most common rate of the inclusion of the molar of the mind following research seems to be characterized by the presence of local factors. One of the most common complications is the impact, ie the inability of the mind molars to erupt on the dental arch. Treatment for the pathology of the mind molars may include observation, extraction, administration of antibiotics, oral surgery, correct orthodontic treatment, or oral hygiene, depending on the nature and severity of the problem. Nanotechnology in the scientific world is a new current, and in dentistry, new branches are already sketched: the nanodiagnotic (cancers diagnosis), the nanoprevention (nanocapsule toothpaste), nanotrataments (odontology, pedodontics, orthodontics, endodontics, surgical treatments, periodontal diseases). Nanomaterials can be simple solutions for solving complex dental problems and can represent the next generation in terms of dental materials development technology
