Caries is the most common non-infectious disease of hard dental tissue in humans and the most prevalent disease in the oral cavity in children and adolescents. In school-age children the majority of caries lesions develop on the occlusal surfaces of teeth, and especially on the occlusal surface of the first permanent molars. Tooth pits and fissures sealing is acknowledged as one of the most effective prevention techniques designed to prevent caries in children and adolescents. Fissures sealing prevent microleakage and bacteria growth in fissure system, and has an important impact on enamel surface remineralization process. Decision for tooth fissures sealing should also considered morphology of fissure system and period of time of a tooth eruption. Additionally, different shapes and depths of fissures of permanent molars have different impacts on the factors that enable the development of caries in fissure systems. On the occlusal surface of not yet fully erupted molars, dental plaque accumulates more rapidly than on molars, which are in function. A likelihood of caries development is lower in appropriate sealed pits and fissures comparing to those not seal. In 74-95% of properly sealed teeth dental caries did not developed after 15 years. Assessing effectiveness of different sealer materials include assessing its durability in fissure system and its efficiency to prevent caries development. Regular dental checking of sealed pits and fissure is also very important. Pits and fissure sealing are safe, effective and highly recommended method aimed to prevent dental cCaries is the most common non-infectious disease of hard dental tissue in humans and the most prevalent disease in the oral cavity in children and adolescents.

COBISS.SI-ID: 28795097Periodontitis with a high prevalence is a chronic inflammatory disease involving the supporting structures of the tooth. The main approach to treating periodontitis, involves the removal of supragingival and subgingival plaque biofilm by means of mechanical debridement. The aim of our study was to evaluate the microbiological effect of repeated antimicrobial photodynamic therapy (aPDT), which followed mechanical debridement, on subgingival biofilm composition in chronic periodontitis. Ultrasonic scaling was done on all teeth supra and subgingivally. Patients were divided into two groups. Control group composed patients receiving only ultrasonic scaling. In treated group ultrasonic scaling was followed by a three aPDT sessions. We used diode laser Helbo Teralite 660nm. In each patient, four samples of subgingival biofilm were collected, 1 from each quadrant. Biofilm samples were collected with sterile paper tips at the baseline and after 1 week, 3 and 6 months after treatment. Microbiological analysis for A. actinomycetemcomitans (A.a), P. gingivalis (P.g.), P. intermedia (P.i.), T. forthytia (T.f.) and T. denticola (T.d.) was performed with Micro-Ident ® Plus test. The additional application of repeated aPDT to ultrasonic scaling would be the suitable treatment to reduce periodontal pathogens in subgingival biofilm.
