Unilocular, multilocular or mixed radiolucency can be seen. Both galls are both unilocular and unilarval. The superior gynoecium has five carpels, each with a 1-celled pistil and unilocular ovaries. The gynoecium consists of three or four carpels, united to form a unilocular ovary. It is the most common radiolucent, benign odontogenic tumor that may be unilocular or multilocular. These areas can be multilocular or unilocular. Secondarily unilocular taxa evolved during the Jurassic and Cretaceous. On radiographs, it can appear as a unilocular or multilocular radiolucency (dark area). The carpel has one style and one stigma, with the ovary unilocular, superior or semi-inferior. From the branches develop a unilocular or multilocular sporangia advance on the branches. Benign and borderline serous tumours are commonly unilocular. Periapical cysts have a characteristic unilocular shape on radiographs. The top (operculum) of the unilocular pixdio releases the urn that contains the seed. In unilocular species, the A form and B form are still present. A single radiolucent area can be seen in smaller tumours (unilocular).
