Ziel der Arbeit war die deskriptive Darstellung der Karies- und Dentalfluoroseprävalenz bei zwei verschiedenen Altersgruppen von Greifswalder Schulkindern im Jahr 2006. Anschließend wurden diese Daten mit Ergebnissen gleichaltriger Schulkinder aus einer Basisuntersuchung(1999/2000)verglichen. Insgesamt konnten 1731 Probanden untersucht werden. Die DMFT/DMFS-Werte bei den 7-10-Jährigen lagen bei 0,14/0,14, 0,21/0,25, 0,35/0,48 und 0,58/0,90. Die DMFT/DMFS-Werte bei den 14-18-Jährigen lagen bei 1,77/2,91, 2,40/3,75, 2,57/4,08, 2,83/4,51 und 2,19/3,45. In beiden Probandengruppen war ein deutlicher Kariesrückgang zu verzeichnen. In Bezug auf die Kariespolarisierung ergaben sich in beiden Gruppen rückläufige SiC-Werte. Bei den Grundschulkindern wurde eine Dentalfluoroseprävalenz von 21,2 % mit vorrangig sehr milden und milden Fluorosen diagnostiziert. Bei den Jugendlichen evaluierte man eine Prävalenz von 10,75 % an Dentalfluorosen mit ebendfalls primär sehr milden und milden Fluorosen.
Therapeutic Sealing of Proximal Tooth Surfaces: Two-Year Clinical and Radiographic Evaluation
(2009)
The diagnosis, prevention and treatment of proximal carious lesions comprise a constant problem in clinical dentistry. The purpose of this investigation was to test the safety and clinical effect of a new treatment for proximal caries. In 50 patients with two proximal initial lesions (D1-3 without cavitation, bitewing X-ray), orthodontic rubber rings were applied to gain access to the interproximal space. One of the lesions was sealed with a thin polyurethane-dimethacrylate foil using a bonding agent (Heliobond®, Vivadent, Schaan/Liechtenstein); the other lesion received oral home-care with dental floss and fluoridated toothpaste and was left as control. In clinical follow-ups after 6 and 12 months and X-ray evaluation after two years, clinical retention of proximal tape and the underlying sealant, marginal adaptation, discoloration, tooth vitality, proximal plaque and gingivitis were checked. In addition, caries was assessed clinically and radiographically. The sealants showed good retention, marginal adaptation and colour. After two years, vitality of all teeth was still positive and no relevant differences in plaque accumulation or gingival status were found between sealed and control teeth. Two sealed surface had to be filled due to caries progression (D3 with cavitation). 9 sealed lesions showed caries regression. In contrast, only 4 control lesions regressed and also two showed progression. The loss of tape had no significant influence on the lesion progression indicating the effect of the underlying bond. All other sealants and control lesions were stable indicating an arrest of the lesion. In conclusion, sealing initial proximal lesions showed no clinical problems and mostly arrest of initial carious lesions on bitewing X-rays.
