Transgingival probing as a potential estimator of alveolar bone level.

The validity of using a periodontal probe for the transgingival sounding of the alveolar crest level has been demonstrated for buccal surfaces of the jaw. The measurements from the occlusal surfaces of the teeth to the estimated level of the alveolar crest using this technique accurately reflected the actual distances measured after surgical exposure of the alveolar crest at these sites.

Serum complement profiles in infants and children.

The purpose of this study was to examine normal serum values for the complement components, C3, C4, and C5, and total hemolytic complement (CH50) activity in 163 healthy infants and children, in the age range from birth through 14 years. There were statistically significant relationships of C3, C4, and C5, but not CH50 with age. None of the complement components or CH50 could be differentiated by sex or race. Tolerance limits for high and low values were projected for each complement measurement for 75%, 90%, and 95% of the general population. Our data confirm the differences in complement levels between children and adults and demonstrate a wide range of values within each group, reflecting the biologic variability of complement measurements. These results emphasize the importance of establishing normal pediatric values in any laboratory that measures complement profiles in various diseases of childhood.

An evaluation of clinical tooth mobility measurements.

This study evaluated the reliability and reproducibility of the modified Miller Index of horizontal tooth mobility. Each of three periodontists utilizing the modified Miller Index assessed the horizontal tooth mobility of 50 teeth in five subjects. The same teeth were also evaluated by the periodontometer. The results of these two methods were then compared. It was found that: (1) there were a high positive correlation between the periodontists' (pooled) assessment of clinical tooth mobility and the measurements of the periodontometer, (2) in any given patient the three periodontists (pooled) were highly accurate in their ability to rank teeth in order of their mobility as determined by the periodontometer, and (3) the periodontists (individually) were not as consistent when comparing teeth with the Miller Index across different subjects. The periodontists did not accurately utilize the Miller Index as it was originally described. It appears that the periodontists either ignored the reference to 1 mm in the description of the Miller Index, or they were unable to estimate what constitutes 1 mm of movemnet in the mouth. The periodontists all consistently scored as a 2 degrees mobility a tooth that moved approximately 0.5 mm not 1.0 mm as described by Miller. It is suggested that the modified Miller Index as described here provides an efficacious system for evaluating horizontal tooth mobility. It provides accurate, reproducible mobility scores in clinical studies requiring an estimation of this parameter. However, for individual teeth, when the clinician or researcher is trying to evaluate the effects of therapy on the periodontium and relatively few evaluation are made, the modified Miller Index may not provide the required degree of sensitively.
