Analogy between the oral microbial flora found at the level of carious lesions, endodontic spaces and prosthetic components

Nowadays, eating habits and lifestyles are moving towards a diet high in sugars and carbohydrates, which is extremely harmful to both oral integrity and systemic health. The aim of the study was to identify the variations between the bacterial plaque formed in carious lesions, infected root canals and prosthetic components, in comparison with commensal oral microflora. The study was carried out on a group of 21 patients aged between 7 and 84 years, 13 women and 8 men, with various oral diseases, which were diagnosed during the specialized examination. The preparation of the medical record, the signing of the informed consent, the anamnesis and the consultation were carried out in the private dental office where the patients presented for a personalized treatment plan, and the examination of the pathological products and the interpretation of the results obtained in the Microbiology Discipline, “Carol Davila” University of Medicine and Pharmacy, Bucharest, Romania. The study carried out on the preparations taken from patients with carious lesions reveals the presence of numerous G+ cocci arranged in short chains (23%), frequent G+ cocci in diplo, thin G+ bacilli with rounded ends and G+ cocci in diplo, arranged in small piles (15 %), and values lower than 8% are represented by G+ in diplo cocci, lanceolate, rare G+ in diplo cocci, very rare fusiform bacilli and dentinal fragments. The study carried out on the preparations taken from the endodontic space showed a remarkable percentage of epithelial cells and leukocytes (28%), rare fusiform bacilli, very small fragments of epithelial tissue, thin G+ bacilli with rounded ends, G+ cocci in diplo and in small piles and buns arranged in short chains (5-6%). The study carried out on the preparations taken from the level of prosthetic components, recorded a relatively high number of epithelial cells (19%), G+ cocci arranged in diplo, lanceolate and in small piles (13%), thin G+ bacilli, with rounded ends (10 %), cocci in short chains (10%) and rare polymorphonuclear leukocytes (10%), while at the opposite pole, squamous epithelial cells, fusobacteria and pleomorphic forms (3%) are found.
