All periapical regions had radiological findings. We identified several
areas in the upper jaw and the mandible with a nuclide enrichment in the
scintigraphy; therefore, we decided to separate four groups of99Tcm uptake intensity: No 99Tcm
uptake (BSgrade: 0); 1: mild 99Tcm uptake (BSgrade:
1); 2: moderate 99Tcm uptake (BSgrade: 2); 3: solid99Tcm uptake (BSgrade: 3). The categories were
summarized and compared to the CB-CT-findings. Based on the categories
of maturation [8] and 99Tcm uptake, we found the
following densities in CB-CT:
In Region 15, 11, 21, 23, 34 and 32: CB-CT°1 (Grade 1): intraosseous
ballooning, thinning of the cortical bone; beginning accumulation on99Tcm scintigraphy (BSgrade: 1). In Region 12, 22, 38,
35, 33 and 31-45: CB-CT°2 (Grade 2): apico-central sclerosis, sclerotic
margin (edging) to cancellous bone increasing accumulation on99Tcm scintigraphy (BSgrade: 2). In Region 14, 13, 26,
27, and 46-47: CB-CT°3 (Grade 3): sclerotic remodellation of the bone
marrow; intense accumulation on 99Tcm-scintigraphy
(BSgrade: 3), and in region 36, 37: CB-CT°4 (Grade 4): periapical
drumstickformation, hypercementosis; decreasing accumulation on99Tcm -scintigraphy (BSgrade: 1-2).
In regions 24 and 25, we did not find 99Tcm
-scintigraphy nor sclerotic chances, nor did we in the highly atrophic
maxilla region 17, 16. No calcification of the pulp, no pulp stones were
detected.
