ACUTE HERPETIC STOMATITIS: CLINICAL MANIFESTATIONS, DIAGNOSTICS AND TREATMENT STRATEGIES.

OBJECTIVE: The aim: To evaluate the recent scientific articles concerning peculiarities of this oral pathology. The goal is to carry out a literature review by evaluating all signs and clinical symptoms related to this disease, so as to provide the clinician with a useful tool for an early diagnosis and treatment of the disease. PATIENTS AND METHODS: Materials and methods: The collection of relevant data were done using the scientific databases Pubmed, Google Scholar. A manual search on Dentistry and Pharmacological sources was also conducted for relevant studies published. The selected key words: ("Herpes virus" OR "HSV") AND ("oral" OR "oral lesions") were used for collecting the data. CONCLUSION: Conclusions: The article presents clinical peculiarities of herpetic stomatitis depending on disease severity and course. Primary herpetic stomatitis appears as spherical clustered vesicles on the gingival and adjacent mucosa. Soon after eruption of elements of lesion they rupture forming painful halo like aphtae / ulcers. Typical symptoms are: pain from ruptured vesicles, lymphadenitis, fever etc. Early diagnosis of disease is important and treatment with antiviral medicaments can modify the course of the disease by reducing symptoms and potentially reducing recurrences. Management of acute herpetic stomatitis include antiviral medicaments intake, maintenance of fluids and electrolytes level in a body. The treatment principles based on etiotropic, pathogenetic and symptomatic therapy are considered in manuscript.

Analysis of the Statistical Comparability of the Hardness and Wear of Polymeric Materials for Orthodontic Applications.

BACKGROUND: Clinical success depends on the contact strength and wear resistance of medical devices made of polymer materials. The scientific goal resulted from the problem of using different methods of surface evaluation of materials used in the production of orthodontic appliances. The purpose of the work was an experimental comparative assessment of indentation hardness and scratch hardness and the sliding wear of four selected polymeric materials used in the manufacture of orthodontic appliances. METHODS: Four commercial materials were compared. Shore hardness tests and a scratch test with a Rockwell indenter were performed. A sliding wear test was performed using the ball-on-disc method. Statistical PCA and correlation analyses were performed. RESULTS: The results of scratch hardness measurements using a contact profilometer correlated with the Shore hardness to a greater extent than measurements made using an optical microscope. PCA showed that Shore hardness explains 45% of the total variance in all the results across the materials. CONCLUSIONS: The scratch hardness method allows for a more explicit ranking of orthodontic polymeric materials when measurements are made with a profilometer. The ranking of sliding wear resistance should be made separately.
