Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to quantitatively measure the rate and amount of calcification and secondary dentin deposition below deep carious lesions of otherwise radiographically and clinically sound teeth treated by calcium hydroxide - methyl cellulose indirect pulp capping. Standardized, reproducible serial radiographs of 50 treated young posterior teeth were exposed preoperatively at one, three, six, nine and, in some cases, 12 months. At the final appointment, the silver amalgam restorations were removed and all residual caries was excavated. A barium sulphate radiographic indicator paste identified the pulpal floor level at the first and last appointments. Ninety per cent of the teeth studied remained asymptomatic and were not pulpally exposed. Television density and linear measurement instrumentation was utilized to register calcification changes, pulpal floor thicknesses, and secondary dentin deposition. Following treatment, increased secondary dentin deposition and Calcification activity, or sclerosis, was initiated. Higher levels of calcification activity were related to increased thickness of pulpal floors, but this dimension had little influence on the total amount of reparative dentin formed. The rate of reparative dentin formation was highest during the first month and steadily diminished with time. Calcification activity experienced a cyclical change, or "exchange," with an initial activity peak. This was followed by an apparent, but temporary mobilization of mineral content •out of the affected dentin. With time, a steady rise in calcification level was observed. Measurement of longitudinal records showed that apparent pulp exposures can be avoided by allowing significant amounts of protective secondary dentin to form, before complete caries excavation.

Indiana University-Purdue University Indianapolis (IUPUI) / This study compared clinical results of two calcium hydroxide bases used in indirect pulp therapy on human teeth. Thirty-four teeth with deep carious lesions were treated with indirect pulp therapy. Eighteen teeth were treated with commercially available Improved Dycal and 16 teeth were treated with an experimental calcium hydroxide formula. Evaluation was made at intervals of three and six months. After three months, periapical and bitewing radiographs were made and the teeth were examined clinically for signs of pulpal degeneration. At the six-month evaluation, in addition to the radiographic and clinical examinations, cavities were re-entered and the unsound residual dentin was removed to ascertain the presence of a so1id dentinal base. Removal of all unsound residual dentin without an exposure of the pulp, as well as the clinical and radiographic examinations, were used to determine clinically successful treatment. In the experimental group 15 teeth were successfully treated; a success rate of 94.4 percent. Seventeen teeth in the control group demonstrated successful indirect pulp therapy; a success rate of 93.75 percent.

Indiana University-Purdue University Indianapolis (IUPUI) / This study was undertaken to investigate histologically the effect of a combination of a potent antibiotic and calcium hydroxide when used as a medication in direct pulp therapy. The pulps of 74 teeth in one Macaca Speciosa monkey and two Macaca Nemestrina monkeys were exposed and left open to the oral environment for 48 hours to insure contamination. These pulps received direct treatment with one of four experimental medications: 1) starch and water; 2) vancomycin, starch and water; 3) calcium hydroxide, methyl cellulose and water; and 4) vancomycin, calcium hydroxide, methyl cellulose and water. In 30 days the teeth were removed from two animals and at 90 days from the other for histologic evaluation. A satisfactory response was observed in all the teeth treated with vancomycin, calcium hydroxide, methyl cellulose and water; in 94.4 per cent of the teeth treated with calcium hydroxide, methyl cellulose and water; in 33.3 per cent of those treated with vancomycin and starch; and in 11.2 per cent of those receiving starch and water. Complete bridging was seen in all teeth treated with vancomycin, calcium hydroxide, methyl cellulose and water. This was confirmed by the use of Procion brilliant red H-8BS dye and the study of serial sections. Under the conditions of this investigation, vancomycin in combination with calcium hydroxide and methyl cellulose was effective in controlling infection and promoting reparative dentin formation in monkeys.
