Our statistical study included 344 participants selected from the patients of the Pedodontics–Orthodontics Discipline of the Tîrgu-Mureş University of Medicine and Pharmacy. The patients’ age was between 6 and 18 years, with an average of 13.70 and a standard deviation of 4.62. The study participants were informed and agreed to complete two questionnaires of our conception regarding their health status, oral hygiene, and motivation for pedodontics or orthodontic treatment. The results of the two questionnaires were interpreted according to the gender and age of the patients. Data processing was performed with NCSS/PASS Dawson Edition statistical software, using the CHI2 test, considering a p of less than 0.05 as significant for comparative results. Results showed that girls were more motivated than boys in addressing pedodontic services due to dental, periodontal, and articular problems. Children, aged between 11 and 14 years, were less intrinsically motivated to solve oral health problems due to their low frequency. The intrinsic motivation for a more beautiful dentition was very strong, regardless of age and sex. Girls were more intrinsically motivated for orthodontic treatment than boys. There was a linear increase together in the age of those who wanted to improve their smile and facial appearance. Children between 11 and 14 years had the best self-perception of the appearance of their teeth, mouth, smile, and facial harmony. The strongest extrinsic motivation for orthodontic treatment came from parents or another doctor. The most important reason for orthodontics was dental malpositions, the last one was the improvement of masticatory efficiency. The extrinsic motivation from parents for orthodontics decreases linearly with age, along with the increase in motivation from the person with whom the participants relate emotionally and from the group of friends.

Introduction Acrylic resins are the most frequently used materials for the bases of prostheses, and are also used in the re-optimization and the repair of prostheses. The aimof our study was to investigate whether direct contact with the resin causes decomposition of methyl methacrylate and formation of ketone bodies in the oral cavity. Material and methods The in vitro study included 12 samples of autopolymerized polymethyl methacrylate and 8 samples of thermopolymerized polymethyl methacrylate. Some of the resin samples were intentionally prepared incorrectly, with modified powder to liquid ratios or thermal regime, to be able to compare them with samples prepared according to the manufacturer’s instructions. Some of the samples were immersed in gastric juice or alcohol for 48 h at 37 °C in a thermostatic bath to simulate the environment and temperature of the oral cavity, while others were kept at room temperature. The Legal reaction was used to identify the presence of ketone bodies in the solutions. Results The samples that were prepared incorrectly and were kept at 37 °C were the most affected. The presence of ketone bodies was demonstrated by the formation of a precipitate on the bottom of the test tube and the color change of the solution. Samples that were

Introduction Halitophobia is also known as false halitosis or psychosomatic halitosis. This pseudo-pathology originates from the somatization of the compulsive idea that the patient has bad breath in the absence of oral pathology. Case Presentation A patient addressed dental surgery complaining of a self-diagnosed halitosis. The dental consultation did not find any dental problem that could cause bad breath. She was referred to a general practitioner for further investigations to rule out a general condition. The investigations revealed a perfectly healthy person, without any chronic ailment that could cause bad breath. The patient refused to consult a psychologist or psychiatrist, considering that she does not have a mental health problem. Conclusions Patients with a suspicion of psychogenic halitosis require psychiatric counseling, and dentists have to be prepared with an efficient strategy for the correct management of these patients.
