Background Molar-incisor hypomineralization (MIH) is a common condition among children that significantly increases the risk of caries. The objective of this research was to evaluate the clinical success of giomer- and conventional resin-based sealants applied on first permanent molars (FPMs) affected by MIH. Methods One-hundred FPMs with MIH which were indicated for non-invasive fissure sealant were selected in 39 children, aged 6–12 years. Using a split mouth design, the FPMs were randomized into two groups; Group 1. Resin sealant (etch-and-rinse + Conceal F) and Group 2. Giomer sealant (self-etch primer + BeautiSealant). Clinical evaluation was performed using the modified United States Public Health Service (USPHS) criteria at 1, 3, 6 and 12 months. The Log-rank, Fisher’s exact test and Kaplan–Meier analysis were used for statistical analysis. Results At 12 months, the retention rates in Group 1 and Group 2 were 68% and %8, respectively (p = 0.000). The cumulative survival rates of conventional resin sealants were significantly higher than giomer sealants for all follow-up visits (p < 0.05). In Groups 1 and 2, the distribution of unsuccessful sealants on mandibular vs maxillary FPMs were 32.1% vs 31.8% (p = 0.612) and 91.7% vs 92.3% (p = 0.664), respectively. Although the success rate was higher for teeth with white opacities or lesions with less extension in Group 1, no significant difference was found. The average survival time was found as 10.46 ± 3.21 months in Group 1 and 4.02 ± 4.43 months in Group 2. Conclusions The conventional resin-based sealants yielded a better clinical performance over the 12-month evaluation period than the giomer sealants which were applied with self-etch primer. The high failure rate observed in giomer sealants could be explained by the possible deficiency in the etching capacity of self-etch primer on MIH-affected teeth.

Background/Aims Traumatic dental injuries (TDIs) in the primary dentition are a significant public health problem, which has been neglected worldwide. Despite its high prevalence, limited studies address this injury. The aim of this study was to determine the characteristics and treatment modalities of TDIs affecting primary teeth, along with accompanying medical co‐morbidities and attendance at follow‐up appointments. Material and Methods This retrospective analysis included all TDIs affecting primary teeth from January 2014 to January 2017. Data abstraction included demographics, time lapse prior to arrival at hospital, trauma etiology, classification of TDIs, soft tissue and supporting bone injuries, medical co‐morbidities, emergency treatment, follow‐up appointments and prognosis. Results Records of 283 children with 536 traumatized primary teeth were reviewed. The median age was 2 years and the maxillary right central incisor (35.1%) was the most frequently injured tooth. Almost half the patients, 46.3%, sought treatment after 24 h. Periodontal tissue injuries (97.2%) predominated TDIs for which fall accidents (82.0%) were the most encountered cause. Most patients (177/283) had accompanying soft tissue/supporting bone injuries and 67.2% had multiple traumatized teeth. Seventy percent of the patients were examined only or were prescribed medication. Survival time following TDIs was unknown in 67.7% of traumatized teeth due to non‐attendance at follow‐up appointments. Most patients (55.1%) did not attend the follow‐up appointments. Conclusions TDIs occurred in the primary dentition with the predominance of periodontal tissue injuries. When TDI was the presenting problem to hospital, accompanying systemic injury was rare. Treatment modalities were mostly limited to examination or extraction. The follow‐up appointments were poorly attended.
SUMMARY Introduction To evaluate the masking effect and color stability of resin infiltration treatment in demineralized (white spot lesion) and hypomineralized (molar incisor hypomineralization) enamel lesions of young permanent anterior teeth. Methods Eighty-four (84) anterior teeth with molar incisor hypomineralization or white spot lesions were treated with resin infiltration. The CIE L*a*b* values of sound enamel and enamel lesions were assessed with spectrophotometer and digital image analysis at baseline, immediate postop, 1 week and 6 months. The difference in ΔL, Δa, Δb, and ΔE measurements between sound enamel and the enamel lesions was compared using the repeated analysis of variance (ANOVA) test at p < 0.05. Results The enamel lesions were clearly discernible from the sound adjacent enamel at baseline. After resin infiltration, there was a significant drop in ΔE values of sound enamel and enamel lesions compared to baseline, and this difference did not change for 6 months, indicating a durable masking effect. At baseline and after 6 months, there was no significant difference in the ΔE values of the test groups. Conclusion The demineralized and hypomineralized enamel defects were effectively masked by resin infiltration, which remained clinically stable for 6 months.
Amaç Bu çalışmanın amacı, ebeveynlerin dişlerin sürme sırası ve zamanları hakkındaki bilgi düzeyleri ile daimi ve süt dişleri ayırt etme yeteneklerini değerlendirmektir. Gereç ve Yöntem Çalışmaya, yeterli kooperasyon düzeyine sahip karma dentisyon dönemindeki çocuk gönüllüler dahil edilmiştir. Ebeveynlerden yüz yüze görüşme yoluyla hazırlanan anketlerdeki soruları yanıtlamaları istenmiştir. İncelenen veriler arasında sosyodemografik bilgiler, dişlerin erüpsiyonuna ilişkin ebeveyn farkındalığı ve ebeveynin daimi/süt dişleri ayırt etme yeteneği bulunmaktadır. Ailelere çocuklarının mandbular ve maksiller sağ taraftaki dişleri gösterilerek süt veya daimi diş olarak belirtmeleri istenmiş ve doğru bilinen toplam diş sayısı hesaplanmıştır. Ek olarak çocukların ağız içi muayenesi tamamlanmış, çürük, kayıp ve dolgu yapılmış süt/daimi (dmft/DMFT) diş skorları kaydedilmiştir. Bulgular Araştırmaya dahil edilen 50 hastanın yaşları 5.3-12.8 yıl arasında değişmektedir (ortalama±SD 8.121±1.524). Tüm katılımcıların dmft ve DMFT skorlarının ortalamaları sırasıyla 6.52±3.17 ve 0.96±1.26 olarak hesaplanmıştır. Dişlerin sürme sırası ve zamanına ilişkin bilgi düzeyini ölçmeye yönelik sorulan beş sorunun tamamını sadece iki (%4) ebeveyn doğru yanıtlamışken, en fazla bir soruyu doğru bilen ebevenylerin oranı ise %34’tür. Ebeveynlere hekim tarafından gösterilen toplam 97 daimi birinci molar dişin %37.1’inin kalıcı dişler olduğu ayırt edilebilmiştir. Bu değer tüm dişler (n=574) için %76.5’tir. Ebeveynlerin sadece %12’si çocuklarının ağzında bulunan tüm süt ve daimi dişleri doğru olarak ayırt edebilmiştir. Sonuç Ebeveynler dişlerin erüpsiyon zamanları ve daimi birinci molar dişler hakkında yeterli bilgiye sahip değildir. Ebeveynlere kazandırılacak olan daimi birinci molar diş farkındalığı, bu dişlerin korunmasının sağlanması, gerekli tedavilerinin ihmal edilmemesi ve erken daimi diş kayıplarının önüne geçilebilmesi adına büyük bir önem taşımaktadır.
