This case report describes the treatment of an 8-year-old girl with anterior dental crossbite using a series of removable appliances to bring the teeth into a normal position. Clinical presentation and intervention: A removable acrylic appliance with a bite plate incorporating a screw was used to correct the anterior dental crossbite and align the incisors. The subsequent eruption of the maxillary left lateral incisor on the palatinal side was treated with a second acrylic plate incorporating a labiolingual spring. After an 8-month period, the anterior crossbite involving multiple incisors was corrected.

The aim of this study was to assess the effect of three root canal irrigation solutions on the apical sealing ability of three root canal obturation materials: gutta-percha/AH plus or MM-seal and Resilon/ Epiphany SE. A total of 100 teeth with single straight root canals were randomly divided into three equal groups of 30 samples each, with the other 10 teeth (5 positive and 5 negative) used as controls. Each irrigation group was divided into three groups according to the use of three different root canal obturation materials (n = 10): Gutta-percha with AH plus or MM-seal, Resilon with Epiphany SE. The crowns were removed at the cementoenamel junction with a diamond disc under water coolant. The root canals were prepared using step-back technique and irrigation with either sodium hypochlorite (2.5%), chlorhexidine (2%), or MTAD solutions. The roots were obturated with lateral condensation technique using one of the obturation materials. The root surfaces was coated with two layer nail varnish (except apex), placed in 2% methylene blue dye solution, and centrifuged at 3,000 rpm for 5 minutes. Irrigation solutions affected the apical sealing ability of all the sealers. The chlorhexidine irrigation solution exhibited higher apical leakage values than did MTAD and NaOCl in all canal sealers, although the MTAD irrigation solution groups showed the least leakage values. The apical sealing ability of AH plus, Epiphany SE and MM-seal root canal sealers decreased when the chlorhexidine was used as an irrigation solution.

The unintentional extrusion of MTA does not prevent the healing of periapical lesions, but may be a delaying factor for periapical healing.

This study aimed to evaluate the reasons for the extraction of primary teeth in primary school-age children in Zonguldak, Turkey. MaterialsandMethods:Age, sex, medical condition, type of tooth extracted, and the reason for the primary teeth extraction were examined retrospectively in the records of patients who applied to Bülent Ecevit University Faculty of Dentistry, Department of Pedodontics between 2012 and 2016. As a result of the examination, information about the reasons for the primary teeth extraction, the type of tooth extracted, and each patient's age and gender were collected and analyzed.Results: A total of 2429 primary teeth were extracted from 1812 children (1013 females and 799 males). Caries (51.6%) was the most frequent reason for extraction of primary teeth. Primary molar teeth (73.7%) were the most common type of teeth was extracted. When the distribution of the reasons for extraction was examined based on age groups, the most prominent reason in the 7-, 8-, and 9-year-old age group was tooth caries (p<0.05), whereas physiologic mobility was the most prominent reason in the 10-and 11-year-old age groups (p<0.05). Conclusion: Based on this study's findings, it can be obtained that tooth caries is the most common reason for extraction of primary teeth in primary school-age children in Zonguldak, Turkey. The most common type of tooth extracted was a primary molar tooth. Oral and dental health programs should be developed and implemented to reduce primary tooth extraction caused by tooth caries.Amaç: Süt dişi çekim nedenlerinin belirlenmesi ülkelerin sağlık politikalarını oluştururken gerekli önlemleri almaları açısından önem taşımaktadır.
