BACKGROUND Caries, enamel hypoplasia, molar incisor hipomineralization, amylogenesis imperfecta, dentine dysplasia, hypophosphatasia and other dental disorders lead to tooth mineralization disturbances and structural abnormalities, decreasing masticatory organ functions. Dental disorders in sheep can lead to premature slaughter before they have attained final stage of their reproductive life an...

Background and Objective: Stem cell therapy is a new treatment option for osteoarthritis. A various applications of stem cell therapy have been used for cartilage regeneration in arthritis patient. The objective of this study was to examine therapeutic effects of puppy deciduous teeth stem cells for the treatment of osteoarthritis using a rabbit model. Methodology: In this study, rabbits were s...

Although periodontal ligament (PDL) cells have previously been isolated from permanent teeth, they have not been isolated from deciduous teeth. Here, we used human telomerase reverse transcriptase (hTERT) induction to establish the first immortalized PDL cell lines derived from deciduous teeth. Cells were transfected with plasmids containing hTERT. Single-cell cloning was then performed using t...

dentinogenesis imperfecta (di) is a hereditary dentin defect caused by an autosomal dominant mutation in dentin sialophosphoprotein gene. defective dentin development results in discolored teeth that are prone to wear and fracture. early diagnosis and proper treatment are necessary to achieve better functional and esthetic results and minimize nutritional deficiencies and psychosocial distress....

BACKGROUND AND AIM: Dental anomalies are typically detected in radiographic screening. The present study was conducted with the aim of investigating the dental anomalies found in panoramic radiographs taken from the study population in Ardabil, Iran, in 2015-2016.METHODS: The present study was conducted on 1800 panoramic radiographs obtained from 799 men and 1001 women in the Radiology Departme...

BACKGROUND AND AIM: Dental caries is a chronic disease with a high prevalence despite its preventability. Untreated dental caries can cause substantial pain and suffering, and imposes a significant public health and economic burden. Our aim was to determine how prevalent and sever dental caries are among school children between 6 to 12 years of age from a mixed population (Jordanians and Syrian...

Introduction Ionizing radiation generates extremly long lived CO2 radicals in calcified tissue. The CO2 concentration rises linearly with dose and can be detected directly by means of EPR spectroscopy (electron paramagnetic resonanc). For retrospective dose estimation tooth enamel and dentine as well as bone samples may be used as in-vivo-dosimeter. Enamel analysis of permanent teeth has been e...

Objective: To determine the frequency of patients who require extraction of permanent premolars among those treated with extraction of deciduous teeth for the correction of incisor crowding in the mixed dentition and analyze possible associated variables. Methods: The sample was composed of orthodontic records of 70 patients with permanent dentition whose treatment had begun in the mixed dentit...

Mature cystic teratomas are a form of ovarian germ cell tumor and often called ‘dermoid cysts’ because they are mostly cystic. Many teratomas have teeth with morphologically identifiable crowns and roots. The objective of this study was to carry out morphometric measurements of teratomatous teeth extracted from a mature cystic teratoma excised from a 28-year-old female patient. The extracted te...
