This paper deals with issues concerning the general and Hungarian-related history of grammar writing on the basis of the first Latin grammar of the Romanian language recently published in two versions, due to the separate work of two scholars. It emphasises some important ways in which that grammar has a bearing on Romanian literature in the Cyrillic script and explores its essential similarities with the rudimenta of morphology and syntax in Alvares’ textbook. It mentions certain recognisable connections with Alvares’ and a few other humanistic Latin grammars, medieval language descriptions, and grammars of Hungarian in Latin. The author considers this grammar an important work of Romance philology in the Carpathian Basin, among other reasons, because it was the first to demonstrate, in the relevant literature of the area, the Latin origin of Romanian on the basis of grammatical correspondences-unlike in the Hungarian literature of the period where the same point was merely made on the basis of correspondences within the word stocks of the two languages.
To assess the prevalence and occurrence of eleven periodontopathogens in subgingival biofilm of banded and bonded molars during the first period of fixed orthodontic treatment. Subjects were selected from patients referred to orthodontic treatment and were divided in two groups: group A comprised fifteen patients (14.4±2.45 years of age) who received orthodontic bands on first permanent molars and group B of ten patients (15.7±1.87 years of age) with directly bonded tubes on the labial surface of the same teeth. Subgingival sample collection was performed before bands and tubes application and 4–7 weeks after attachment placement. DNA-strip tehnique was used to assess the presence of eleven putative periodontopathogens at each time point. Fusobacterium nucleatum, Eikenella corrodens and Capnocytophaga spp. were found in a large number of samples, other periodontopathogens were present in a smaller rate. The 4–7 weeks after attachment placement a slight increase of putative species was observed in both groups.
The presence of orthodontic tubes and bands influence the accumulation and composition of subgingival microbiota. Higher level of oral hygiene should be achieved before and during orthodontic treatment in order to prevent any side effects on periodontal tissues.
