Objective: To evaluate the pulpal temperature changes due to the polymerisation of resin and glass ionomer based materials in dentine thicknesses in immature permanent teeth with open apices. Material and Methods: Forty extracted sound human third molar teeth with open apices were included. The width of the cavities prepared on the occlusal surface was 4×5 mm. The depth was 2 mm in the resin groups. 4 mm in the groups in which glass ionomer liner was applied before composite restoration. The coronal parts of the samples were then placed on an acrylic plate with three gaps for feeding-extraction needles and the thermocouple. The temperature changes were recorded. The data was analyzed by SPSS. Statistical significance was accepted as p<0.05. Results: The temperature increase in the group of 1 mm remaining dentin thickness revealed higher results than the values detected from the 2 mm group (1.01 °C) (p=0.00). The mean values (1.49 °C, 1mm) of temperature changes in only glass ionomer applied group were lower than the avarage values (2.210°C, 1mm) determined in the polymerization process of resin composites with light-emitting diode devices. Conclusion: In a remaining dentin thickness of 1 mm in teeth with open apices, using a glass ionomer liner might be a useful effort for protecting the pulp from the heat generated by polymerisation devices.

Background: Pediatric dentists should have information regarding whether mouth opening is limited. In clinical practice, these professionals should collect and record oral area measurements at the pediatric patient's first medical examination. Objectives: The study's aim developed the standard mouth opening measurement in children by using ordinary least squares regression to develop a clinical prediction model in children with Temporomandibular Joint Ankylosis before preoperative surgery. Methods: All participants completed their age, gender, and calculated height, weight, body mass index, and birth weight. Pediatric dentist performed all mouth‐opening measurements. The oral‐maxillofacial surgeon marked subnasal and pogonion points for the lower facial length of soft tissue. It was measured using the distance between the subnasal and pogonion with a digital vernier caliper. The widths of the three fingers (index, middle, and ring fingers) and four fingers (index, middle, ring, and little fingers) were also measured using a digital vernier caliper. Results: Maximum mouth opening showed that three‐finger width (R2 = 0.566, F = 185.479) and four‐finger width (R2 = 0.462, F = 122.209) had a significant influence on the Maximum mouth opening (MMO) (p < 0.001). Conclusion: Pediatric dentists should collaborate with the treating maxillofacial surgeon to manage long‐term treatment needs for individuals with Temporomandibular Joint Ankylosis.

Objective: The objective of this study is to evaluate the wall adaptation and apical microleakage values following the application of various irrigation protocols in primary teeth.Material and methods: For the two parts of the study, extracted upper incisor primary teeth were randomly included to the 1% sodium hypochlorite (NaOCl), 10% ethylenediaminetetraacetic acid (EDTA)+1% NaOCl, 6% citric acid (CA)+1% NaOCl and 0.9% physiological saline (PS) groups. Canal wall adaptation and apical microleakage were assessed by scanning electron microscopy (SEM) and stereomicroscope, respectively.Results: 6% CA + 1% NaOCl group was found to be the most successful irrigation protocol in providing strong canal wall adaptation and less apical microleakage, followed by 10% EDTA +1% NaOCl. 6% CA +1% NaOCl was significantly superior regarding apical microleakage (p < .05).Conclusions: Due to the ability to provide appropriate changes in the root canal walls to make a well-adapted and leak-proof canal filling, 6% CA + 1% NaOCl can be recommended as an irrigation protocol in primary teeth.
