A radiographic image of a demineralized area corresponding to a carious lesion is not a well defined radiolucency as the degree of calcification increases towards the periphery of the lesion, therefore detecting the true extent of caries is difficult (5,6).
It offers radiolucency through the whole working length of the table.
RB: mild stage, which includes RB4 (radiolucency that reaches the 1/3 half of the dentin), RC: extensive stage, which includes RC5 (radiolucency reaching the A inner dentin, clinically cavitated), and RC6 (pulp radiolucency, clinically cavitated).
Intraoral radiographic examination revealed that the root of maxillary left central incisor was bent distally at an angulation more than 45 to the crown portion, and well-defined periapical radiolucency was seen at the root apex [Figure 2].
3 In about 90 percent of the cases, a well-defined radiolucency at the apical area of an untreated asymptomatic tooth with a non-vital or diseased pulp is either a dental granuloma or a radicular cyst.
The radiographic view showed there was an improvement of periapical radiolucency.
The demographics of patients, the number, size, side, location, and radiolucency of stones in kidneys, placement of JJ stents, shock number, energy, seance number, stone-free rate, and complications were noted.
The lateral radiographic image (Figs 1 and 2) revealed a soft tissue swelling around the left carpus and the radiolucency noted, consistent with a nondisplaced oblique fracture of the extensor process of the carpometacarpus.
A third party selected 10 panoramic films (5 with implants and 5 without) and 10 periapical radiographs (5 with peri-implant radiolucency and 5 without) from the digital record archive in the prosthodontics clinic at the University of Puerto Rico, Medical Sciences Campus; these radiographs were randomized.
The radiograph taken at the first month follow-up visit showed a decrease in the radiolucency at the cyst site and the impacted teeth straightening (Figure 4).
Panoramic radiograph was performed to show a well delimited unilocular radiolucency located in the left body of the mandible, extending distally from the tooth 35 to the ramus of the mandible (Fig.
A radiographic review of the components showed no radiolucent lines in 45 knees, and two knees (4%, one femur and one tibia component) had at least 1 mm of radiolucency in a single zone in one component.
