Numbers of patients recruited and crowns successfully fitted by study dentists. Of the 45 children who had crowns fitted, all 45 reported the procedure as being acceptable, and would have it again. Of the 45 crowns fitted, parents declared the technique as acceptable in 44 cases. For one case, the parent initially didn't like the colour of the crown, but was satisfied at one week review. 4 Dentists were asked to give their subjective impression of the discomfort experienced by the child during the cementation of the crown, and the results are shown in Table 3.
Percentages are additive.
The sizes of the crowns fitted are shown in Table 5. Dentists were asked to record by how much the occlusion was propped open after crown cementation, when measured from the incisors. This is shown in Table 6. Forty-five crowns were successfully fitted using the Hall technique for 49 of the patients recruited. It was disappointing that four of the eight dentists failed to meet their targets for patient recruitment, despite having over six months to complete the trial.
