    This 12-week clinical study evaluated the impact of 10% CPP-ACP and 5% sodium fluoride varnish regimes on the regression of nonorthodontic white spot lesions (WSLs). The study included 21 children with 101 WSLs who were randomised into four treatment regimes: weekly clinical applications of fluoride varnish for the first month (FV); twice daily self-applications of CPP-ACP paste (CPP-ACP); weekly applications of fluoride varnish for the first month and twice daily self-applications of CPP-ACP paste (CPP-ACP-FV); and no intervention (control). All groups undertook a standard oral hygiene protocol and weekly consultation. Visual appraisals and laser fluorescence (LF) measurements were made in weeks one and twelve. The majority of WSLs in the control and FV groups exhibited no shift in appearance, whereas, in the CPP-ACP and CPP-ACP-FV groups, the lesions predominantly regressed. The visual and LF assessments indicated that the extent of remineralisation afforded by the treatments was of the following order: control ~ FV < CPP-ACP ~ CPP-ACP-FV. Self-applications of CPP-ACP paste as an adjunct to standard oral hygiene significantly improved the appearance and remineralisation of WSLs. No advantage was observed for the use of fluoride varnish as a supplement to either the standard or CPP-ACP-enhanced oral hygiene regimes

    Effect of Er:YAG laser enamel conditioning and moisture on the microleakage of a hydrophilic sealant

    For a given sealant, successful pit and fissure sealing is principally governed by the enamel conditioning technique and the presence of moisture contamination. A new generation of hydrophilic resin sealants is reported to tolerate moisture. This study investigates the impact of Er:YAG laser pre-conditioning and moisture contamination on the microleakage of a recent hydrophilic sealant. Occlusal surfaces of extracted human molars were either acid etched (n = 30), or successively lased and acid etched (n = 30). Ten teeth from each group were either air-dried, water-contaminated, or saliva-contaminated prior to sealing with UltraSeal XT® hydro™. Samples were inspected for penetration of fuchsin dye following 3000 thermocycles between 5 and 50 °C, and the enamel–sealant interfaces were observed by scanning electron microscopy (SEM). Significant differences in microleakage were evaluated using the Mann–Whitney U test with Bonferroni adjustment (p = 0.05). Laser pre-conditioning significantly reduced dye penetration irrespective of whether the enamel surface was moist or dry. Microleakageof water-contaminated acid etched teeth was significantly greater than that of their air-dried or saliva-contaminated counterparts. SEM analysis demonstrated good adaptation in all groups with the exception of water-contaminated acid etched teeth which exhibited relatively wide gaps. In conclusion, this hydrophilic sealant tolerates the presence of saliva, although water was found to impair its sealing ability. Laser pre-conditioning significantly decreases microleakage in all cases

    Bu klinik çalışmada opak lezyon gelişimi üzerine, standart bir remineralizasyon protokolüne ek olarak kullanılan fluoridli vernik, CPP-ACP ve CPP-ACP+fluoridli vernik uygulamalarının etkinliğinin incelenmesi amaçlanmıştır. Çalışma 8-15 yaş arası 21 çocukta opak lezyon saptanan toplam 101 diş yüzeyi üzerinde 12 hafta boyunca yürütülmüştür. Hastalar rastgele dört gruba ayrılmıştır. Kontrol grubu oral hijyen eğitimi, klorheksidin gargara ve xylitollü sakız çiğnenmesini içeren günlük bir remineralizasyon protokolü ile tedavi edilmiştir. Kontrol grubundaki protokole ek olarak, ikinci grupta fluoridli vernik, üçüncü grupta CPP-ACP ve dördüncü grupta fluoridli vernik ve CPP-ACP kullanılmıştır. Bütün protokollerin etkinliğini değerlendirebilmek için remineralizasyon öncesi ve sonrasında görsel skorlamalar ve DIAGNOdent Pen değerleri kaydedilmiştir. Bu çalışmanın sonucu CPP-ACP nin gözle muayenede başarısının, vernik ile veya vernik olmadan anlamlı derecede yüksek olduğunu göstermiştir (p <0.001 ve p <0,001). Buna ek olarak CPP-ACP kullanılan gruplarda DIAGNOdent Pen değerinde anlamlı olarak azalma belirlenmiştir. CPP-ACP nin standart protokole olumlu ve önemli katkı sağladığı ve opak lezyonu tedavi potansiyeli olduğu bu kısa süreli klinik çalışmada gösterilmiştir.The aim of this clinical study is to investigate the effectiveness of fluoride varnish, CPP-ACP and CPP-ACP and fluoride varnish applications in addition to a standard remineralization protocol used for the white spot lesions development. 21 children between the ages of 8-15 on a total of 101 tooth surfaces with white spot lesion treated for 12 weeks. The patients were randomly distributed into four groups. Control group was treated for a daily procedure of remineralization protocol including oral hygiene education, chlorhexidine mouthwash and chewing-gum with xylitol. In addition to the protocol of control group, second group had fluoride varnish, third had CPP-ACP and fourth had fluoride varnish with CPP-ACP. Before and after the remineralization protocols carried out, visual and DIAGNOdent Pen scores was recorded to compare the efficiency of all procedures The results of this study has shown that CPP-ACP with varnish or without varnish was significantly higher values in the success of visual examination (p <0.001 and p<0.001). In addition, CPP-ACP groups were determined significantly higher reduction in DIAGNOdent value. CPP-ACP itself seems to have an additional benefit to standard procedure and have a potential for treating white spot lesions in this short-term study

    Can zirconia crowns be the first restorative choice after endodontic treatment of primary teeth?

    Objective Early loss of primary teeth due to caries can cause temporary or permanent problems, such as occlusion disorders, aesthetic problems, nutritional problems, abnormal habits, and speech disorders. Although the development of restorative materials has led to significant improvements, failures are still frequent. The purpose of this study was to evaluate the success rates of zirconia crowns compared to other crowns for the restoration of endodontically treated teeth with excessive loss of material. Methods A total of 45 teeth of patients aged under 10 years, including primary molars and anterior teeth, requiring restoration after root canal treatment, were included in this randomized, non-blinded clinical study. Stainless steel (SSC), zirconia (ZC), and strip (SC) crowns were used and compared clinically and radiographically during a six-month follow-up period. Parents were asked to fill out a questionnaire at one week and six months to evaluate the parent and child satisfaction levels. The patients' pain and discomfort levels were assessed using a visual analogue scale. The Mann-Whitney U, Chi-Squared and Friedman and Cochran Q tests were used for statistical comparisons using IBM SPSS Statistics version 23 (IBM, Armonk, NY, USA). Results The six-month follow-up evaluations revealed no significant differences in clinical outcomes between the SSC, ZC, and SC groups. There were no significant differences between the groups with respect to parent and child satisfaction. Conclusion The clinical outcomes of ZCs were comparable to those of the other crowns. ZCs could be a choice for aesthetic purposes, with the disadvantage of a higher cost
