She taught and lead by example; her immense capacity for love and patience and her limitless faith in God and the goodness of mankind was reflected in her daily interactions with friends, coworkers, students, and everyone she came into contact with. She embraced every day and lived it to the fullest reminding all of us who knew her that life is fleeting and precious and we should treasure every day. I also dedicate this edition to all my past and present dental hygiene students. I am honored to have played a part in your education and have enjoyed watching you grow not only as adults but as professional dental hygienists. You have provided me with an education second to none and I thank you. And to my father and mother, Earl and Muriel Yarrington, who always told me I could do anything I put my mind to. I wish you could have seen the completed project. To my husband, Richard, and my son, Brian, you have been never ending sources of strength and encouragement and I thank you for having patience with me while I was working on this. Leslie DeLong To my husband, Alan, who continues to inspire me, and to my children, Anna, Michael, and Stephanie; thank you for reminding me of what is important in life.

The objective of this study was to determine the predictors of osteoradionecrosis (ORN) which were associated with a dental extraction post radiotherapy. Methods: A retrospective analysis of medical records and dental panoramic tomogram (DPT) of patients with a history of head and neck radiotherapy who underwent dental extraction between August 2005 to October 2019 was conducted. Results: Seventy-three patients fulflled the inclusion criteria. 16 (21.9%) had ORN post dental extraction and 389 teeth were extracted. 33 sockets (8.5%) developed ORN. Univariate analyses showed signifcant associations with ORN for the following factors: tooth type, tooth pathology, surgical procedure, primary closure, target volume, total dose, timing of extraction post radiotherapy, bony changes at extraction site and visibility of lower and upper cortical line of mandibular canal. Using multivariate analysis, the odds of developing an ORN from a surgical procedure was 6.50 (CI 1.37–30.91, p 0.02). Dental extraction of more than 5 years after radiotherapy and invisible upper cortical line of mandibular canal= on the DPT have the odds of 0.06 (CI 0.01–0.25, p < 0.001) and 9.47 (CI 1.61–55.88, p 0.01), respectively.

Abstract. The study was conducted to assess the clinical, functional and biochemical state of the oral cavity in children and adolescents with dentoalveolar anomalies against the background of bronchial asthma. A comprehensive epidemiological examination was carried out in 225 children and adolescents, divided into two groups. The main group of 180 included patients with dentoalveolar anomalies and deformity, suffering from bronchial asthma, and the Control group of 45 patients without somatic pathology. Both groups were divided into age categories 6-9 years old, 10-13 years old and 14-18 years old. In the course of clinical research, the state of hard tissues of the tooth, periodontal tissues and the oral mucosa, as well as the frequency of dentoalveolar anomalies and deformities, the level of oral hygiene were studied. Keywords: children and adolescents, oral cavity, bronchial asthma, dentoalveolar anomalies and deformities, clinical and functional state, biochemical characteristics. Relevance of work. The epidemiology of major dental diseases in children and adolescents with bronchial asthma indicates a high prevalence of caries and non-carious lesions of the hard tissues of the tooth, pathology of periodontal tissues and oral mucosa [10, 21].

Our goal is a comparative analysis of the assessment of quality of life in patients with type 2 diabetes mellitus complicated by chronic kidney disease after the use of orthopedic dental treatment. Analysis of questionnaires showed that the quality of life of patients with partial absence of teeth was reduced to a varying degree in all groups of patients. Summarizing the results of the study, we can conclude that the correct deontological approach using the developed recommendations for the collection of anamnesis will facilitate understanding by the dentist of the algorithms and methods of treating the patient and help to improve the quality of prosthetics and further rehabilitation. Key words: diabetes, Dental diseases, kidney disease, orthopedic dentistry, Tongue plaque. Introduction In recent years, the role of chronic inflammation in the development and progression of atherosclerosis, obesity, metabolic syndrome, insulin resistance has been actively discussed.3 Diabetic neuropathy complicates the course of diabetes in 60-90% and is dangerous for the development of diabetic foot syndrome.

  • 267 Eruption of the Upper Wisdom Tooth Among The
    Analele UniversităŃii din Oradea Fascicula:Ecotoxicologie, Zootehnie şi Tehnologii de Industrie Alimentară, 2012 ERUPTION OF THE UPPER WISDOM TOOTH AMONG THE YOUNG PEOPLE OF ORADEA Todor Liana* *University of Oradea, Faculty of Medicine and Pharmacy, Department of Dental Medicine [email protected] Abstract Wisdom teeth have the highest chronological variability in their eruption, their appearance on the arcade being made between 16-25 years. Less than 5% of adults with the full complement of teeth have sufficient space for the complete eruption of the third molars. Thus, it play a predominant role in the incidence of retention. With retention can be connected infections, cysts, tumours, neuralgiform pain, anomalies of tooth position, masticatory dysfunction, disturbances of occlusion and myoarthropathies. A study based on gender was made on the number of erupted upper wisdom teeth in the oral cavity. Thus, an individual may present one, two or not even one upper wisdom tooth in the oral cavity. Upper wisdom teeth present in the oral cavity have also been studied in terms of eruption progress: fully erupted or in eruption, as well as in terms of the eruption axis: on the axis or protruded. Key Words: rash, upper wisdom tooth, protruded. INTRODUCTION Eruption of permanent teeth is usually easy without any occuring disorders in the incisors, canines and premolars, while spontaneous exfoliation of deciduous teeth occurs through progressive root resorption. Also, the eruption of the first two molars generally does not cause accidents. The most common accidents are related to the lower wisdom teeth eruption and to a lesser extent to the upper wisdom teeth eruption.
