Methods OPGs were evaluated for 1,571 subjects (807 males, 764 females) with mean age (8.72 ± 2.5) years. Unerupted permanent teeth prior to emergence into the oral cavity were assessed. The Chi square test was used to determine statistical differences between the group showing and the group not showing the defect with regards to sex, stage of dental development, presence of developmental anomalies, and condition of primary predecessor teeth. Results Prevalence was (8.1 %) by subject and (0.62 %) by teeth. All subjects showed only one affected tooth per subject with no significant gender differences. The highest prevalence was in mandibular first premolars (3.02 %). Most defects were noted in the mixed dentition stage (89.06 %), mainly in the mandible (79.7 %) as single lesions at a mesial location intracoronally, and a size of less than one-third of dentine thickness in (50 %). Among all variables examined, PEIR defects were significantly associated with mixed dentition stage (p = 0.000) and decayed/ filled primary predecessor teeth (p = 0.028). Conclusions PEIR defects occur at a significant prevalence rate in unerupted teeth. Increased awareness and careful radiographic examination of unerupted teeth may improve early detection and treatment of PEIR defects in children.

Materials and Methods: A total of 709 questionnaires were filled out. Data collected included: demographic data, oral health knowledge, and self-reported oral health practices and dental service utilization. Descriptive statistics and Chi-square analysis were performed; significance level was set at P < 0.05. Mean age was 20.8 ± 1.5 years. Results: There were (90.1%) of students who considered the toothbrush an oral hygiene aid, (91.1%) thought fluoride was beneficial to teeth, and almost (80%) students believed smoking has harmful effects on oral health. Regarding oral health practices, nearly half of the samples reported twice daily tooth-brushing, one-third received regular dental check-ups, and half visited the dentist because of pain or bleeding gums; fear was the main reason for not visiting the dentist. Females primarily visited the dentist for esthetic reasons (70%) and males upon complaint (59.8%). Oral health knowledge and practices among university students were poor. Conclusion: Dental students showed higher knowledge and better practices among disciplines studied. It is also important that dental hygienists take an active role in educating students in the aspect of oral health.

Diagnostic criteria are based on the generalized enamel defects, severe taurodontism especially of the mandibular first permanent molars, an autosomal dominant mode of inheritance, and at least one of the other features (i.e., nail defects, bone sclerosis, and curly, kinky or wavy hair present at a young age that may straighten out later). Confusion with amelogenesis imperfecta is common; however, taurodontism is not a constant feature of any of the types of amelogenesis imperfecta. Management of TDO requires a team approach, proper documentation, and a long-term treatment and follow-up plan. The aim of treatment is to prevent problems such as sensitivity, caries, dental abscesses, and loss of occlusal vertical dimension through attrition of hypoplastic tooth structure. Another aim is to restore function of the dentition and enhance the esthetics and self-esteem of the patient. This paper proposes treatment approaches that include preventive, restorative, endodontic, prosthetic, and surgical options to management. In addition, it sheds light on the difficulties faced during dental treatment of such cases.

To establish a threshold cemantoenamel junction (CEJ)-alveolar bone crest (ABC) distance in healthy 6-to 9-year-old Jordanian children and determine the effect of pathological changes, physiological changes, gender, and age on the CEJ-ABC distance. Design. Bitewing radiographs were made for 539 6-to 9-year-old children. Plaque index (PI), gingival index (GI), calculus index (CI), DMFS score, and pocket depth were all assessed through clinical examination. CEJ-ABC distance was measured from radiographs at the mesial surface of permanent first molars (PFM), and the mesial and distal surfaces of primary molars.

This study's purpose was to compare the cutting efficiency of an Er:YAG laser versus diamond burs in primary and permanent teeth in order to measure thermal effects on the pulp and evaluate lased surfaces using scanning electron microscopy (SEM). A total of 80 primary and permanent teeth were used. Crater depths and mass loss were measured after delivering laser pulses at varying energies onto sound or carious enamel or dentin using the Key-3 laser. Control samples were cut using diamond burs in an air turbine handpiece. Thermal changes were measured using miniature thermocouples placed into the pulp chamber. Lased surfaces were evaluated using SEM. Laser ablation crater-like defects were deeper in dentin than enamel at the same pulse energy. Greater ablation rates for dentin and enamel and significantly more efficient removal of carious tooth structure by laser was present in primary teeth. Te...
