“…If the medium for some reason had to be in-jected through the mucosa, the correlation was somewhat poorer. Cunningham 6 Penick (1968), however, using a similar technique, found no correlation between the characteristics of the radiopaque image and the histologic diagnosis, Thus it may be concluded that the radiographic diagnosis of periapical lesions is still doubtful, except when using a contrast medium injected through the root canal as reported by Forsberg 6 Hagglund (1959). However, this method, because of the controversial findings by Cunningham 6 Penick (1968), has to be further clarified.…”

Brynolf (1967), in an investigation of 292 maxillary incisors, showed that it is possible radiographically to distinguish between histologically normal and pathologic cases, and among the latter it is possible to distinguish between groups of different degrees of severity.…”

Abstract— A clinical and radiographic study was undertaken on 1,600 periapical lesions from 1,133 patients referred for extractions or apicoectomies. The clinical findings as well as the radiographic size (diameter) of the lesions were recorded. When this diameter measured less than 5 mm, the pathologic tissue was left in the bone after extraction, whereas in cases where the lesions were 5 mm or more, an excochleation was done and the specimens subjected to a routine histologic examination. In the group consisting of 753 controlled periapical lesions less than 5 mm in diameter all cases healed uneventfully within two years. The distribution of all periapical lesions according to regions was found to be in good correlation with caries frequency. Likewise the distribution within the dental arch of histologically verified granulomas and cysts was compared with earlier reports. A statistically significant higher proportion of cysts was found in the premolar than in the molar region (0.025 > P > 0.02), whereas the opposite was true regarding granulomas. The preoperative radiographic diagnosis showed only poor correlation with the histologic diagnosis. Fistulae occurred more often in connection with granulomas than with cysts (statistically significant, 0.025 > P > 0.01).

“…Smith & Woods (1983) tested a calcium hydroxide–diatrizoate paste. Diatrozoates are substances that have been used previously to aid in the diagnosis of periapical lesions (Forsberg & Hagglund 1960, Cunninghan & Penick 1968) and to elucidate the pathways of anaesthetic injections (Berns & Sadove 1962, Galbreath 1970). A commercially available soluble iodine compound (Renograffing) containing aqueous solutions of 66% diatrizoate meglumine and 10% sodium diatrizoate was mixed with calcium hydroxide powder and compared with a barium sulphatecalcium hydroxide paste.…”

REVIEW ARTICLE: Calcium hydroxide has been used in endodontology for many years. The aim of this paper is to review the various formulations of calcium hydroxide that have been described, with specific reference to the vehicle used to carry the compound. The requirements for a vehicle are described, and ex vivo and in vivo studies reviewed. Vehicles can be classified into aqueous, viscous and oily, the clinical properties of calcium hydroxide changing depending on the vehicle. The review also describes the use of various active components that have been added to calcium hydroxide, including antimicrobial and anti-inflammatory agents. This review will help clinicians to make informed judgements about which formulations of calcium hydroxide should be used for specific endodontic procedures.
