A field-trial of two restorative materials used with atraumatic restorative treatment in rural Turkey: 24-month results

OBJECTIVE: The purpose of this study was to investigate the clinical performance of high-strength glass ionomer cement (HSGIC) and resin-modified glass ionomer (RMGIC) in single and multiple surface carious cavities in the field conditions. MATERIAL AND METHODS: A split-mouth design, including ninety-one fillings placed on contra lateral molar pairs of 37 children, was used in permanent dentition. As filling materials, a HSGIC (Ketac Molar/3M ESPE) and a RMGIC (Vitremer/ 3M ESPE) were used with the Atraumatic Restorative Treatment (ART). Baseline and 6, 12 and 24-month evaluations of the fillings were made with standard-ART and USPHS criteria by two examiners with kappa values of 0.92 and 0.87 for both criteria. RESULTS: According to the USPHS criteria, the retention rates of RMGIC and HSGIC restorations were 100% and 80.9% for single surface, and 100% and 41.2% for multiple surface restorations after 24 months, respectively. Irrespective of surface number, RMGIC was significantly superior to HSGIC (p= 0.004), according to both standard-ART and USPHS criteria. CONCLUSION: The results indicate that RMGIC may be an alternative restorative technique in comparison to high-strength GIC applications in ART-field-trials. However, further clinical and field trials are needed to support this conclusion

Evaluation on different preventive measures in the children living in rural districts of south-eastern anatolia: 24 month-result of a field trial

Son yıllarda, değişik ülkelerde izlenen yaygın çürük azalımına rağmen, Türkiye gibi gelişmekte olan çoğu ülkelerde diş çürüğü hala önemli bir sağlık sorunu olarak devam etmektedir. Çok değişkenli bir hastalık olmasına rağmen, çürüğün kontrol altına alınmasındaki temel sorunlarda birisi de koruyucu-tedavi edici uygulamaların, toplumun değişik seviye­lerine ulaştırılmasındaki güçlüğüdür. Bu çalışmada; dişhekimiiği hizmetinin sınırlığı olduğu Güneydoğu Anadolu kırsalındaki çocuklarda değişik koruyucu uygulamalar incelenmiştir. Diyarbakır kentine 55 kilometre uzaklıktaki Eğil ilçesi yatılı bölge okulu çalışma alanı olarak seçildi. Yaşları 9-17 arasında değişen toplam 120 çocuk 3 gruba ayrıldı. Bunlar; grup 1: cam-ionomer fissür örtücü gurup, grup 2: kontrol grubu ve grup 3: florjel grup. Tüm koruyucu uygulamalar okul ortamında ve bir grup dişhekimi ve dişhekimiiği öğrencisi tarafından gerçekleştirildi. İki hekim tarafından gerçekleştirilen ilk muayenenin sonrasında çocuklar ikinci yılın sonunda tekrar muayene edildi. Grup 1A 2 ve 3 için iki yıllık ortalama çürük artışı sırasıyla 00.07±0.6, 0.82±0.95, 0.68±0.75 olarak belirlendi. Gruplar arasındaki fark istatistiksel olarak anlamlı bulundu (p<0.0001). Sonuç olarak; sınırlı şartlara rağmen, ART yüzey örtücüler gibi basit koruyucu uygulamaların Güneydoğuanadolu uzak kırsalında yaşayan çocuklarda etkin olabileceği belirlendi.Despite dramatic and common reduction in various countries, dental caries is still epidemic in various developing countries as seen in Turkey. Although it is a mult/factorial disease, one of the basic problems to fight with dental caries is the limitations of the preventive and operative treatment alternatives to attain to various part of the community. In this study, various preventive measures have been studied in a child group living in rural south-eastern Anatolia in where dental service is limited. A regional boarding school in Eğil district, 55 kilometers Diyarbakir city, was selected as study site. One-hundred-twenty children whose age range was 9 to 17 were divided 3 groups as follows; group 1- ART-glass-ionomer sealant group, group 2- control group, and group 3- fluoride gel group. Each preventive procedure was performed in the school promises by a group of dentist and dental students. After the baseline examination performed by two dentists using WHO caries criteria, re-examination was performed at 24* month. Mean caries increment for group 1, 2 and 3 were 0.07&plusmn;0.6, 0.82&plusmn;0.95, 0.68&plusmn;0.75, respectively. The differences were statistically significant (p&lt;0.0001). It was concluded from these results that although limited preventive opportunities, pragmatic preventive measures such as ART-fissure sealant, could be effective in the children living in far-rural of south-eastern Anatolia

The Effect of Prophylactic Polishing Pastes on Surface Roughness of Indirect Restorative Materials

The purpose of this study was to evaluate the influence of prophylactic polishing pastes (PPP; Detartrine (DT), Topex (TP)) on surface roughness (Ra) of indirect composites (IRC; Tescera (TES), Gradia (GRD), and Estenia C&B (EST)), a glass ceramic (Empress 2 layering (E2)), and a leucite reinforced glass ceramic (Empress Esthetic (EE)) with two different (glazed (G); polished (P)) surface preparations. A total of 90 IRC and 120 ceramic discs, 8 mm in diameter and 2 mm thick, were prepared. E2 and EE specimens were randomly divided into two groups (n=30). One group was glazed (GE2; GEE), while the other group was polished (PE2; PEE) the same as the IRCs. The specimens in each group were subsequently divided into three subgroups: control (C), DT, and TP. Ra (μm) was evaluated with a profilometer. Data were analyzed by Kruskal Wallis, followed by the Dunn's multiple comparison tests P0.05. PE2 and PEE were not affected by DT or TP P>0.05, while GE2 and GEE exhibited significant roughening after TP P<0.05. Surface roughness of IRCs and glazed ceramics can be affected by PPP applications
