ABSTRACT
The hypothesis was tested that variations in the temperature of gingival crevices are linked to variations in plaque formation. Fifty-nine abutment teeth to removable partial dentures were studied during four experiments, under various conditions of plaque formation, i.e. not brushing the teeth whilst wearing and not wearing dentures, and performing ordinary and then specialized tooth brushing whilst wearing dentures. The collation of temperature curves with plaque curves revealed a proportional relationship between the rate and magnitude of plaque formation and the rate and magnitude of the recorded temperature changes. Furthermore, the removal of plaque resulted in a reversal of induced temperature rises. The lowest crevicular temperatures were obtained with the practice of the specialized tooth brushing.

Temperatures were recorded in thirty-two gingival crevices adjacent to proximal surfaces of abutment teeth fitted with minor connectors of an open space design, and in thirty gingival crevices adjacent to proximal surfaces fitted with minor connectors of a closed design. During the 2 week experimental period, the twenty-seven removable partial denture subjects who were involved in the study kept the accumulation of plaque to a minimum by applying specialized tooth-brushing. Although an equal but small amount of plaque formed in both groups, the presumed minimal rise in temperature stimulated by this plaque did not prevent the two connector designs from showing disparate effects on the crevicular temperature. It was concluded that the open space design of minor connector is less conducive to irritation of the adjacent marginal gingiva than is the closed design.

The relationship of plaque accumulation to two different designs of a proximal minor connector, was studied in twenty-seven removable partial denture wearers. On thirty proximal surfaces adjacent to a closed space design, and on thirty-two surfaces adjacent to an open space design, plaque formation was recorded using a plaque scoring system. Mean plaque scores were calculated separately for the two types of design, and no difference was found between the two sets of scores.

In two experiments, each running for 2 weeks, plaque formation was studied on forty-two teeth acting as abutments for removable partial dentures. In the first experiment, only ordinary tooth brushing was practised. Plaque accumulation was rapid, yielding scores ranging between 2 and 5. In the second experiment, following instruction in intensive tooth brushing, plaque scores were depressed to approximately 1.5 and below.

In nineteen subjects, temperatures were recorded thermo-electrically in the vestibular and proximal crevices of fifty-nine teeth. It was found that the formation of a new plaque was followed by a rise in crevicular temperature. In addition, it was found that the normal as well as the abnormal crevicular temperatures were higher in the mandible than in the maxillae.
