Dentigerous cyst is a type of odontogenic cysts and generally occurs in the ages of twenties or thirties. Dentigerous cyst always includes a tooth which cannot complete the eruption process and occurs around the crown by the fluid accumulation between the layers of enamel organ. In rare cases, dentigerous cyst occurs in the first decade of life and develops in an immature permanent tooth as a result of a chronic inflammation of overlying nonvital primary tooth. In this report, a case of dentigerous cyst in primary dentition in a 5-year-old child patient and its treatment were presented. The dentigerous cyst was totally enucleated, and the unerupted permanent first premolar tooth was removed from the primary mandibular right premolar region. There was no recurrence observed after 18 months follow-up.

Objective:The aim of the present study was to determine the prevalence of supernumerary teeth with by evaluating a large group of adult patients in Turkey and to investigate the characteristics of supernumerary teeth with their complications and treatment options.Study Design:This descriptive and retrospective study was carried out in 7348 adult patients aged over 18 years (3212 females and 4136 males). The characteristics of the supernumerary teeth were noted and the diagnosis was made during clinical and radiographic examination with the help of panaromic, periapical, and occlusal radiography. Information on the demographic variables for each patient, including age and gender, were colleceted.Materials and Methods:All supernumerary teeth were classfied under several titles such as location, position, morphology, eruption, clinical complications, and treatment protocols. The data obtained were subjected to statistical analysis. Chi-squared test was used to determine differences in distribution of supernumerary teeth when stratified by gender. The statistical significance was established by confidence interval of 95% (P ≤ 0.05).Results:123 (2.14%) affected patients (69 females and 54 males) were observed with a female:male ratio of 1.28:1 (P < 0.05). One hundred and fifty-six supernumerary teeth were detected in all affected patients.Conclusion:Supernumerary teeth may be observed in adults patients with a similar frequency (2.14%) as in children and young adolescents, and clinicians should take measures and examine all patients carefully even at older ages.

Background:An ideal root canal obturation requires a complete dentinal wall adaptation of sealer and Gutta-percha combinations without any gap formations.Aims:The aim of the study was to evaluate the dentinal wall adaptation ability of MTA Fillapex root canal sealer using stereo electron microscope (SEM).Methods:Twenty-four, single-rooted, human maxillary incisor teeth were used. All canals were prepared with a rotary nickel–titanium (Ni–Ti) instrument to a size F3 file. Teeth divided into two equal groups and one of the experimental groups was filled with AH Plus, and the other group was filled with MTA Fillapex using Gutta-percha single cone as a core material. The roots were prepared for SEM evaluation, and serial scanning electron photomicrographs were taken at ×50, ×100, ×500, and ×1000 magnifications. The gaps between the root canal sealer and canal walls were detected and measured in coronal, middle, and apical thirds. For each section, the highest value among the detected gap formations was recorded.Statistical Analysis:Mann–Whitney U-test, Freidman, and Wilcoxon tests were used.Results:The statistical analysis showed no significant difference between two sealers in terms of gap formation (P > 0.05).Conclusions:MTA Fillapex has a similar dentinal wall adaptation ability as AH Plus does.

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

Anah tarKe li me ler Öz AbstractObjective: Determination of the factors causing the extraction of primary teeth is important for countries to take the necessary precautions while establishing their health policies. 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. Bu çalışma Türkiye'nin Zonguldak ilindeki ilkokul çağı çocuklarında süt dişi çekimine neden olan etkenlerin belirlenmesini amaçlamıştır. Gereç ve Yöntemler: Çalışmamızda 2012-2016 yılları arasında Bülent Ecevit Üniversitesi Diş Hekimliği Fakültesi, Pedodonti Anabilim Dalı'na tedavi amacıyla başvuran hastaların kayıtlarında yer alan yaş, cinsiyet, tıbbi durum, çekilen diş sayısı

Supernumerary teeth may affect the tooth eruption negatively if they occur on the eruption way, and the treatment choice is usually the extraction to prevent the impaction of adjacent permanent teeth. CBCT enables clear and three dimensional images, and it may be helpful to determine the exact location and to measure the dimensions of the supernumerary tooth to avoid any complication during the extraction process. The aim of the present study was to evaluate the accuracy of CBCT on measuring the tooth length and crown width of impacted supernumerary teeth. Twenty-five impacted supernumerary teeth were evaluated using CBCT, and each sample's tooth length and crown width were measured prior to the extraction. After all the extractions were completed, the actual measurements were performed on the same samples. The differences between CBCT and actual measurements were evaluated statistically. Measurements on CBCT images were significantly larger than the actual measurements on tooth length and crown width. For tooth length and crown width, p value was found as 0.045, and <0.001, respectively. The results of the present study should be considered as important by clinicians during the treatment planning to decrease any complication risk under certain conditions such as being so close to an important anatomical structure or the root of an adjacent tooth.

To evaluate the impact of three different education methods on the oral hygiene levels of school children using clinical and theoretical findings. Material and Methods: 144 children (72 males and 72 females), whose ages ranged between 8-13, were divided into 12 equal experimental groups according to their ages and gender. They were all considered to have poor hygiene. Only one out of the three different education methods (brochure, model or video) was applied to each group. The percentage change in PI, GI, BOP and theoretical test points from the baseline to the 6th months were evaluated. The data was statistically analysed by using Kolmogorov-Smirnov and One-way ANOVA tests. Results: Reduction in PI, GI and BOP scores was significantly greater (p<0.05) in the video applied groups compared to the brochure groups in the age of 8-10 groups for both genders and in 11-13-year-old males. In 11-13-year-old females, all methods showed similar results (p>0.05). There was no significant difference in test points in 8-10 and 11-13-year-old female groups (p>0.05), whereas a significant increase in test points was observed in the video and model applied groups compared to the brochure groups in 8-10 and 11-13-year-old male groups (p<0.05). Conclusion: It may be more helpful and effective for children to get the oral hygiene education using the visual methods, especially for those under the age of ten.
