The effects on the gingivae of chewing fibrous foods

Abstract: The present investigation was undertaken to study the changes in the gingivae of a group of human subjects whose only active effort at oral cleanliness was to chew raw carrots. Eighteen male dental students 20–24 years of age, were studied using the Gingival Index system (GI) of Loe and Silness (1963), the Plaque Index system (P1I) of Silness and Loe (1964) and gingival exudates measurements according to Egelberg (1964). The participants were told not to use any active oral hygiene measures for a period of eighteen days. During this time, nine of the students were given three raw carrots three times a day. These were carefully chewed for two to three minutes under supervision. That the regular chewing of raw carrots had no influence on the degree of plaque formation, is proved by the fact that at no examination was the difference between the Plaque Index scores of the experimental and the control groups statistically significant. Thus, the active mastication of the raw carrots appeared to have no significant toothcleansing effect. This investigation has also demonstrated that, when all active tooth cleansing is discontinued, healthy gingivae will develop chronic inflammation and pre-existing gingivitis will gradually become aggravated. The Gingival Index scores and exudate measurements clearly indicate a gradual deterioration of the gingivae of all the subjects throughout the eighteen days of experiment. The increases in the GI-values and in the gingival exudation were of the same magnitude in both the experimental and the control groups. This shows that the chewing of fibrous food had no influence on the rate of deterioration of the gingivae when no tooth-cleansing was practiced.

Instructions to Supplement Teaching Oral Hygiene

Abstract: : The booklets was prepared to instruct patients on oral hygiene procedures. It was designed to complement, not take the place of, chair-side teaching. The section 'Personal Recommendations for Your Mouth' at the end of the booklet, permits the clinician to prescribe for particular situations or areas. Using the booklet as a daily guide, the patient more quickly attains a high degree of proficiency in oral hygiene, and less of the clinician's time is required for chair-side instruction.

Oral hygiene and occlusal disharmony in Mexican-American children

Abstract: Ninety-five Mexican-American children ranging in age from 5 to 13 years of age and residing in Muscatine, Iowa were examined using the Simplified Oral Hygiene Index (OHI-S) and the Orthodontic Treatment Priority Index (TPI) to test the hypothesis that the children with the most severe handicapping malocclusions would also exhibit the poorest oral hygiene An approximately equal number of males and females were divided according to age into three groups (5–7, 8–10 and 11–13) The TPI and OHI-S scores for each child within a group were ranked so that the Spearman rank correlation coefficient could be calculated and tested for significance using the “t” test There was observed to be no significant correlation between oral hygiene as scored by the OHI-S and occlusal disharmony as scored by the TPI

Method of oral hygiene in certain difficult problems.

Abstract: CLINICIANS have been confronted for many years with the problems of oral hygiene in certain difficult problem groups. The oral surgeon is confronted with a cleansing method for the oral fracture patient with intermaxillary wiring. The orthondontist is constantly aware of the problem of hidden caries and debris beneath orthodontic appliances and bands. The prosthodontist and general practitioner is often plagued with the problem of poor oral hygiene involving those teeth that support prosthetic appliances. In addition to these difficult problems, we add the problem of oral hygiene in the mouth cancer group, in which surgery or surgery and irradiation have been employed as a method of treatment. Tissue healing and slough add to the problem. Many methods of oral hygiene are familiar to the dentist. In the past we have attempted to establish and maintain oral hygiene for all of these special groups in addition to handicapped children with

Personal factors in dental disease prevention: i. a test to measure dental health knowledge

Abstract: : A dental health knowledge test was devised and was evaluated in 106 Submarine School students. Criteria of evaluation consisted of response distribution spreads, and objectively evaluated gingivitis and oral hygiene. A test score, derived from selected questions, was found to be significantly correlated with the objectively assessed health factors. It is concluded that the dental health knowledge test can be used in the Navy preventive dentistry studies.

Report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

Abstract: While the development of new knowledge is proceeding, it is also important to recognize and use the knowledge we think we have now. We have had the capability, for many years, of preventing the loss of most teeth from caries and periodontal disease if we would only use what we know about diet, fluoridation, oral hygiene, and what we have learned about function from gnathology. Unfortunately, diagnosis and treatment planning is the most neglected area in dental practice. If a fraction of the time, effort, expense, and intelligence was applied to prevention that is brought to bear on dental problems to make the recovery, some real progress would be made. Many of you, I know, have been accomplishing comprehensive oral care for years rather than temporizing so that the teeth can be lost comfortably. It is no wonder that so many people have been resigned to the eventual loss of all of their teeth. We have broken dental teaching up into manageable segments for convenience, now we are trying to unite them again with the total care concept. However, all is not drab, and there is an encouraging gradual change toward using some of the procedures more generally that have been found, clinically, to be very effective for a long time.

The use of synder's caries activity test in oral hygiene effectiveness monitoring.559.

Abstract: : Dental caries is a rather slowly progressing disease. At least a year is required to evaluate a preventive measure by means of a reduction in the caries incidence. The Snyder's caries activity test which is based on the acid production by the oral bacteria seemed an attractive short term assessment tool for hygiene effectiveness. Six subjects used three different hygiene methods and their 'caries activity' was measured before and after the hygiene procedures. The results were essentially negative with regard to any hygiene method significantly reducing the caries activity. In all cases, however, an extreme degree of reproducibility was noted in the individual's caries activity. It is concluded that the test is a useful tool for characterizing an individual's caries activity, but the usually employed hygiene methods are not reflected in a changed activity.
