BackgroundThe Hall technique (HT) involves the placement of stainless steel crowns for treating asymptomatic carious primary teeth without tooth preparation or caries excavation.AimTo investigate whether temporomandibular dysfunction (TM‐D) manifests in children after HT.DesignHealthy children (age: 5‐9 years) with dentin caries were treated with HT in a university clinic, and TM‐D signs and symptoms were monitored in this cohort clinical trial. The primary outcome was TM‐D signs recorded using the clinical dysfunction index (Di) at pre‐treatment: 0‐, 1‐, 3‐, 6‐, and 12‐month follow‐up visits. The secondary outcome was TM‐D symptoms recorded using a questionnaire. The Di and symptoms were compared over time using McNemar's tests.ResultsThirty‐nine children were followed for 12 months after HT treatment. Four children were detected as having dysfunction signs throughout the study: muscle pain on palpation and clicking. The symptoms ‘hearing a sound within the jaw joint’ or ‘bite felt uncomfortable or unusual’ were reported by another four children. The Di and TM‐D symptoms were not significantly different between pre‐treatment and follow‐up visits (P > .05).ConclusionsThe HT does not seem to be connected to TM‐D. Alternative TM‐D assessment tools for studying non‐persistent symptoms more comprehensively might be useful for future studies.

The aim of this study was to assess the ability of self‐assembling peptide (P11‐4) diffusion, assembly, and remineralization to effect artificial secondary caries‐like lesions in human primary teeth in vitro. Enamel‐dentin blocks obtained from extracted human primary molars were embedded into epoxy resin blocks. Cavities (approximately 1 × 1 × 2 mm) were prepared on the surface using a high‐speed diamond bur under constant water cooling and filled with composite restorative material (Filtek Z250; 3 M ESPE). The samples were immersed in demineralizing solution (20 ml) for 96 h to produce secondary caries lesions and divided into two groups according to the testing materials: fluoride varnish (Duraphat; Colgate, UK) and P11‐4 (Curodont Repair; Credentis, Switzerland). Except for the control areas, all samples were remineralized for 3–5 min using the remineralizing agents, and then all the sections were placed in a pH‐cycling system for 5 days at 35°C. The pH cycling procedure was followed by micro‐CT analysis for the qualitative evaluation of surface changes. The Mann–Whitney U test was used to compare two independent groups. In the comparison of more than two dependent groups, Bonferroni smoothed pairwise analyses were used to determine the source of the Kruskal–Wallis H test difference. The results of the study revealed that the remineralization depths of the peptide group were higher than those of the fluoride group (p < .01). There was a statistically significant difference in remineralization effects between the fluoride and peptide groups. P11‐4 can be considered as an effective remineralizing agent for secondary caries lesions.

ÖZET Amaç: Hall teknik (HT) süt azı dişlerinde preparasyon yapıl-madan ve çürük uzaklaştırılmadan paslanmaz çelik kuron (PÇK) simantasyonuyla uygulanabilen minimal girişimsel bir diş tedavi yöntemidir. Preparasyon yapılmadan PÇK'nın simantasyonu sonucu HT oklüzal dikey boyutu arttırmaktadır. Çalışmamızın amacı HT uygulaması ile restorasyon sonrası dikey boyut artışının, tedaviden öncesiyle, hemen tedaviden sonra, 15. ve 30. gününde karşılaştırılmasıdır. Gereç ve Yöntem: Çalışmaya çapraz kapanışı ve parafonksiyonel hareketleri olmayan; çürük diş sayısı 1 ile 3 arasında değişen (5-9 yaş arası) velilerin bilgilendirilmiş onamıyla 16 sağlıklı çocuk dahil edildi. Her çocukta dentin çürüklü ve odontojen kaynaklı bir enfeksiyon ya da pulpa iltihabı şika-yeti bulunmayan bir süt azı dişi seçildi ve HT ile restore edildi. Overbite (OB) miktarı alt ve üst kanin dişler arası temas ile ölçüldü. Dikey boyut karşılaştırması tedavi öncesi, tedaviden hemen sonra, 15. gün ve 30. günlerde OB ölçümü ile yapıl-dı. Overbite ölçümleri Friedman testi ve Bonferoni düzeltmeli Wilcoxon testi ile karşılaştırıldı. İstatistiksel anlamlılık düzeyi p< 0.05 olarak kabul edildi. Bulgular: Overbite tedavi öncesi ile tedaviden sonra, 15 ve 30 gün sonrasında fark göstermiştir (p<0.001). İkili karşılaştırma sonuçlarına göre tedavi öncesi OB değerleri ile tedavi sonrası (p<0.001) ve 15. gün OB değerleri (p=0.008) anlamlı farklı saptanmıştır. 30. günün sonunda ise OB değerlerinde, tedavi öncesine göre anlamlı bir fark görülmemiştir (p>0.05). Sonuçlar: Hall teknik ile tek dişi restore edilen bu olgularda tedaviden hemen sonra ölçülen OB değerleri, tedavi öncesi-ne göre yüksek bulunmuştur ancak bu fark 30. gün sonunda ortadan kalkmıştır. Çalışmamıza göre paslanmaz çelik kuronun neden olduğu erken temas 15-30 gün arasında ortadan kalkmakta, tedavi öncesinden overbite farksız hale gelmektedir.Anahtar kelimeler: Paslanmaz çelik kuron, oklüzyon, dikey boyut SUMMARY Aim: Hall technique (HT) is a minimally invasive restorative method that consists of cementing stainless steel crowns on cavitated primary molars without preparation. The aim of this study is to compare occlusal vertical dimensions at pretreatment, immediately after, 15 and 30 days after in HT application. Materials and Methods: Sixteen systemically healthy children aged between 5 and 9, without crossbite, parafunctional oral habits; with 3 maximum clinically and radiologically diagnosed aproximal caries (without pulpitis, periapical infection) whose parents consented were enrolled in the study.
