Possibility of ultrasonic diagnosis in dentistry

U radu je prikazana mogućnost primjene ultrazvučnih dijagnostičkih metoda u stomatologiji. Do sada se ultrazvuk u stomatologiji koristio isključivo za sterilizaciju instrumenata, čišćenje instrumenata i neke terapijske svrhe kao: npr. čišćenje zubnog kamenca, punjenje zuba itd. Autori su u svom radu primijenili jednodimenzionalnu ultrazvučnu (A-Scann metodu) i dvodimenzionalnu (B-Scann) metodu za dijagnostiku bolesnog zuba, te temporomandibularnog zgloba. A- Scann metoda je rađena aparatom Ehopan Siemens sondom 2 i 4 mHz promjera 10 mm. Na sondu je fiksirana vodena kupelj vlastite konstrukcije, tako da se pritiskom sonde mogao prilagoditi promjer kontaktne površine zavisno od površine ispitivanog zuba. B-Scann metoda je rađena na aparatu Diosonograf - 4102 sa sondom frekvencije 2,5 MHz promjera 13 mm uz aplikaciju vodene kupelji vlastite konstrukcije. Rezultati ispitivanja jasno su pokazali korisnost ultrazvučnih dijagnostičkih metoda u stomatologiji. Ultrazvučne dijagnostičke metode imaju prednost jer su neinvazivne, lako izvedive i bezopasne za bolesnika, a otvaraju mogućnost šire dijagnostičke primjene.The possible applications of ultrasonic diagnostic methods in dentistry are presented. Untill now ultrasound in dentistry has been used only in sterilisation and cleaning of instruments and in some therapeutic purposes such as the tartar cleaning, tooth filling etc. The autors applied onedimensional ultrasound (A-scann) method and twodimensional ultrasound (B-scann) method in diagnostics of the healthy and affected tooth and of the temporomandibular joint. A-scann method was done using the Echopan Siemens probe of 2 and 4 MHz of 10 mm diametar. The probe was provided with the water cap of our own construction. Thus by pressing the probe we could adjust the diametar of the contact area depending upon the area of the tooth examined. B-scann method was done using the Diosonograf 4104 mashine with a probe frequency of 2.5 MHz diametar 13 mm, appying water cap of our own construction. The obtained results have clearly indicated the advantages of the ultrasonic diagnostic methods in dentistry. The advantages of these methods are that they are non-invasive, easy to apply and without any rise for the patient. It is also possible to apply them in wider diagnostic purposes
