PREVALENCE OF OSTEOCEMENTODYSPLASIA IN STOMATOLOGICAL PATIENTS BY THE CONE-BEAM COMPUTER TOMOG
Abstract and keywords
Abstract (English):
Predmet. Osteocementodisplazii (OCD) – gruppa displasticheskih obrazovaniy, harakterizuyuschihsya perestroykoy normal'nyh komponentov gubchatoy kosti s preobladaniem fibroznoy tkani i cementopodobnogo materiala. Gruppa OCD vklyuchaet periapikal'nuyu, fokal'nuyu i florid OCD. Dlya OCD harakterna stadiynost' razvitiya i patognomonichnaya rentgenologicheskaya semiotika. Cel' issledovaniya. Izuchit' rasprostranennost' OCD u ambulatornyh stomatologicheskih pacientov po dannym konusno-luchevoy komp'yuternoy tomografii. Metodologiya. Byli oceneny dannye klinicheskogo obsledovaniya i konusno-luchevye tomogrammy 2380 chelovek, obrativshihsya v stomatologicheskuyu kliniku s razlichnymi zhalobami. Soglasovannost' mezhdu ekspertami ocenivalas' s pomosch'yu kappy Koena (k). Poluchennye znacheniya kappy Koena interpretirovalis' soglasno znacheniyam kappa po tablice Landis i Koch. Znachimost' rezul'tatov issledovaniya vychislyalas' s pomosch'yu t-kriteriya St'yudenta. Rezul'taty. Rasprostranennost' OCD sredi ambulatornyh stomatologicheskih pacientov po dannym konusnoluchevoy komp'yuternoy tomografii sostavila 1,1 %. V 52 % sluchaev vyyavlena POCD, v 41 % – FOCD, v 7 % – sochetanie POCD i FOCD. Sootnoshenie muzhchin i zhenschin – 1 : 2,6. Vo vseh sluchayah OCD byli bessimptomny. V 96 % izmeneniya lokalizovalis' v nizhney chelyusti, v 4 % – v verhney chelyusti. Vyvody. Osteocementodisplazii – porazheniya chelyustey s harakternoy rentgenograficheskoy i tomograficheskoy semiotikoy, diagnostirovat' kotoruyu nuzhno s pomosch'yu kliniko-rentgenologicheskih metodov. Rezul'taty konusnoluchevoy komp'yuternoy tomografii pozvolyayut ob'ektivno ocenit' lokalizaciyu, rasprostranennost' porazheniya, sostoyanie kortikal'nyh plastinok chelyustey i sootnoshenie s okruzhayuschimi anatomicheskimi obrazovaniyami.
