A comparative preliminary physiological and microbiological study on gingivitis and Periodontitis(Clinical – Laboratory study)

Abstract

Introduction: based on the seriousness (danger) of oral diseases due to the negative effects they have on the human masticatory function, a preliminary study was necessary to compare the severity of gingivitis and periodontitis according to the physiological aspects of the masticatory muscles and the microbiological aspects and their response to some bacterial species that cause oral infections not responding to traditional home treatment.

Materials and methods: Samples were collected by the Periodontal Department – Faculty  of Dentistry .They consisted of two groups (40 Gingivitis samples equally belonging to men and wome, and 40  periodontitis samples also belonging equally to men and women). Next, the bite force of the patients was measured using a bite force in Research Laboratory - Department of Basic Sciences - Faculty of Dentistry meter. The differences  of the averages of the two groups were analyzed using Excel, that was followed a test of sexual resistance of Enterococcus sp. and Streptococcus sp. to chlorhexidine, which is one of the strongest oral anti-bacterial applied as a mouthwash with a concentration of 0.12%.

Results:  After comparing the averages of bite forces for both societies, it was foundont  that  the periodontal infection was more affected by biting forces than gingivitis, and that men were less affect   by both types of infection than women, except in cases of advanced infection. form a microbiological point of view, both Enterococcus sp. and Streptococcus sp. showed medium sensitivity to chlorhexidine at a concentration of 0.12% applied as an oral rinse.

Conclusions: Periodontal infection is the most dangerous even in its later stages, especially in women, who are more affected according to the study results,  which also showed that the chlorhexidine applied as oral rinses with  low concentrations is moderately effective against the most common bacteria that cause gingivitis and periodontal infections of the tissues around the tooth in the case of home application, whether preventive or curative.
