Objective: The purposes of this study were to determine the quality of final orthodontic treatment outcome and average treatment time with fixed lingual brackets compared to labial brackets. Our hypothesis was that labial fixed appliances produce a higher quality of final treatment outcome, and a shorter average treatment time compared to lingual fixed appliances. Materials and Methods: This was a retrospective study of matched pairs. Records of twenty subjects treated with lingual appliances were included. These were paired with twenty patient records of subjects in fixed labial appliances with matching initial discrepancy index (DI) (±5 points), Angle classification (within one-half step), number of extracted teeth, and age. Final models were scored using the eight criteria of the American Board of Orthodontics’ Objective Grading System (OGS) and treatment time was recorded in number of days. Results: The mean difference in OGS scores between groups was 2.00 ± 8.89 points with a mean OGS score of the labial and lingual fixed appliance groups of 21.6 ± 7.45 and 19.6 ± 6.43, respectively. This difference was not statistically significant (p = 0.33). Lingual subjects’ treatment time was an average of 4.25 ± 213.78 days less compared to their matched labial subjects. This difference was not significant (p = 0.93). A statistically significant difference was found in the buccolingual inclination subcategory of the OGS. The mean difference in the buccolingual inclination score of lingual subjects was 1.90 ± 3.52 points higher than labial subjects (p = 0.03). Conclusion: Lingual fixed appliance subjects had no significant difference in treatment time and / or treatment outcome as measured by OGS when paired with labial fixed appliance subjects, however, they did have significantly higher buccolingual inclination discrepancies.

Amelogenesis Imperfecta (AI) is a rare, hereditary disorder that causes a defect in enamel mineralization in the primary and permanent dentitions. Amelogenesis imperfecta is generally categorized as hypoplastic, hypocalcified, or hypomaturation form based on the primary enamel defect. However, distinctive clinical features may be seen in each variant. Moreover, compromised esthetic appearances, tooth sensitivity and loss of occlusal vertical dimension are the common clinical problems observed in these variants. The objective of this review was to discuss the management strategies for patients with amelogenesis imperfecta. Definite diagnosis and adequate treatment planning are ensured for patients clinically presented with different forms of AI. Clinicians should provide preventive care and establish an early permanent therapy plan for these patients. Nevertheless, an interdisciplinary approach is required to improve both esthetic and functions. Moreover, there is a need for long-lasting restorative solutions for AI patients.

Stem cells are undifferentiated cells that have the ability to perpetuate themselves through self-renewal, repairing of damaged tissue and to generate mature cells of a particular tissue through differentiation. In humans, there are broadly two types of stem cells embryonic stem cells, which are derived from the inner cell mass of the blastocyst, are omnipotent and maintain their telomerase length thus capable of unlimited self-renewal. The second one is adult stem cells which are tissue specific have less capacity for self-renewal and ability to maintain their telomeres is limited and not sufficient to prevent their senescence therefore are at high risk of malignant transformation. Because over expression of telomerase activity in normal mesenchymal stem cells is correlated with accumulation of mutations.4,5

The integral analysis of the Temporomandibular Joint (TMJ) and the osteo-ligament-articular and muscular structures was carried out together with their associated neural network. This determined the high degree of correlation of the factors that affect the dynamic-functional balance of the Temporomandibular System (TMS) and the self-dynamics of the System. Finite element studies were used to represent the effects of load factors (G forces) in the laboratory and over military combat aircraft, to try to extrapolate the results to field work. The dynamic parameters of the TMJ were measured, using a variable load factor (force G) imposed on the pilots in a sequence of military flights. The application of sustained load factor allowed to visualize in a short period of time, what would take a researcher years to observe, about the typical anomalies of the temporomandibular system and the associated dynamic structures in a patient, besides being able to study the relaxation time that the masticatory system needs, in order to recover its physiological stability, understanding which are the adaptation mechanisms for it. It was determined that not only asymmetric efforts (responsible for the multiple positions of each tooth or dental prosthesis), are responsible for generating harmful loads on the Temporomandibular System, but also have a high degree of correlation, in general, with the damage caused at the TMJ, due to alterations in biomechanical lever systems. Therefore, the methodology of dental treatments must be reconsidered, starting from functional recovery, through appropriate biomechanical mechanisms, to then give way to the corresponding dental rehabilitation, which will result in the functional stability of the masticatory system, dental-prosthetic rehabilitation and the balance integral of the body understanding the masticatory system, as an integral part of a Whole (Holistic Vision).

There are approximately 12 million residents with disabilities in Egypt. Despite national legislation to assure individuals with disabilities, neededservices are difficult to secure since social views exclude them from functioning as member of a community. The general social outlook to patients with disabilities ranges from barriers which restrict the inclusion and normalization in society to general limitation in the availability dental services. Specifically, in terms of oral health care, there is limited preparation of dental students in Egypt (particularly, exposure in predoctoral training programs) to provide care for this population. Examples of dental education accreditation standards in other counties are used as models for the improvement of dentals students in Egypt to provide services for these individuals. Further emphasis is needed to prepare dentists (including those in current practice) and healthcare professionals to provide, healthcare for patients with special health care needs. This article explores the gaps from social stigma to predoctoral training in Egypt in an effort to improve oral care and general healthcare for patients with special need.

Primary prevention includes all actions aiming to reduce the risk of new carious lesions. It uses individual prevention (food, hygiene, and vaccinations) and collective (drinking water distribution, waste disposal, food safety). This conception of prevention leads to a broad program improving the quality of life and reforming institutions, to assesses the dangers to humans of harmful work environments (toxic risk, lighting conditions, load handling, occupational stress and health) as well as physical or occupational constraints.

A variety of esthetic restorative materials has been introduced in the past decades for restoring primary incisors. However, knowledge of the specific strengths weakness and properties of each material will enhance the clinician’s ability to make the relevant choice of selection for each individual personalized treatment plan. The objective of this review was to discuss the advancements in esthetic restorations for restoring primary incisors in a clinical situation. Individualized treatment planning and optimum professional judgement is essential for selecting the extra coronal restorations for primary dentition. Nevertheless, CAD/CAM crowns can be promising alternative options for full-coronal coverage. Moreover, long-term follow-ups and further clinical trials are required to support the evidence.

SDF consists of 25% silver, 8% ammonia, 5% fluoride, and 62% water at pH 10. This is ultimately referred to as 38% SDF.
