The effect of odontogenic sinusitis with periapical lesions on quality of life.

<b> Introduction:</b> Usually the symptoms presented in odontogenic sinusitis do not differ from chronic sinusitis of other origin. However, odontogenic sinusitis is considered as an independent disease which requires specific diagnostic approach and treatment. </br></br> <b>Aim:</b> The aim of the study is to define the main symptoms of odontogenic rhinosinusitis with periapical lesions and its impact on the quality of life. </br></br> <b>Material and methods:</b> The SNOT-22 and OHIP-14 questionnaires were distributed among 26 symptomatic patients suffering from odontogenic sinusitis with periapical lesions in the teeth that remain in close contact with the maxillary sinus floor. Data was collected by means of an interview and standard examination performed by an otolaryngologist and a maxillofacial surgeon. The symptoms were also objectified using nasal endoscopy and radiological studies. The acquired data was statistically analyzed. </br></br> <b>Results:</b> The total OHIP-14 score was 14.7 ± 11.3, whereas the total SNOT-22 score was 44.6 ± 18.8. Women scored significantly higher in the total SNOT-22 score as well as domains concerning nasal symptoms, quality of sleep, and emotional symptoms. The answers given in similar items were comparable between both questionnaires. </br></br> <b>Conclusions:</b> Properly diagnosed odontogenic sinusitis (OS) with periapical lesions (PAL) will improve the quality of health-care and spare the patients inadequate procedures. Standard examination should include a unified and validated question-naire concerning both sinonasal and oral symptoms. Painful aching in the mouth and discomfort during eating might help to identify the OS with PAL during a medical interview and help both ENT (ear-nose-throat) specialists and dentists to establish proper patient-oriented diagnosis and treatment.

The effect of decontamination procedures on elastic polymeric materials used in dental mouthguards fabrication.

PURPOSE: Mouthguards are commonly used in the prevention of head and mouth injuries in many sport disciplines. Elastic polymeric materials used in their fabrication absorb the energy of impact. However, decontamination procedures may cause damage to their surface causing deterioration of their properties and favouring pathogen colonization. The aim of the study was to determine the impact of different cleaning methods on mouthguard materials, surface quality. METHODS: The material for the research consisted of 81 samples made from polymeric materials used for custom mouthguard fabrication - Impak, Corflex Orthodontic and Erkoflex. Samples were viewed under a scanning electron microscope after exposure to different cleaning methods. RESULTS: Statistical analysis of tested decontamination procedures and disinfecting agents showed statistically important ( p < 0.05) results for the presence of small and big separated pieces, grooves and holes. Out of all the cases the lowest indicator for occurrence was in the disinfecting spray - Aftermat. CONCLUSIONS: Considering the importance of the surface material of the mouthguard, disinfection should be the method of choice for maintaining its hygiene. Impak material samples, cleaned with the Aftermat spray, showed the lowest range of damage.
