Abstract
Background and Aim: Ectodermal dysplasia (ED) is a hereditary disease that affects ectodermal tissues. Its oral manifestations include hypodontia or oligodontia, which cause the reduction of the height and width of the alveolar ridge. Considering numerous difficulties that these patients encounter with regard to facial appearance, talking, and chewing, their rehabilitation has a major influence on their quality of life. Implantation therapy is considered as a successful therapeutic protocol for substitution of such teeth. This article is a review of implant rehabilitation of ED patients and the related management procedures.
Materials and Methods: In the present review article, the English articles in PubMed, ScienceDirect, MEDLINE, and Google Scholar databases from January 2000 to December 2017 have been investigated using the following keywords: anodontia, dental implants, ectodermal dysplasia, and hypodontia.
Conclusion: There is a multilateral approach to the treatment of ED patients according to their age, the status of oral soft and hard tissues and the remaining teeth. Implantation therapy for such patients is similar to that of non-ED patients.

Abstract
Introduction: The antibacterial effects of coconut products have been extensively studied in the recent years. Due to the high prevalence of periodontal disease and the role of Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) in periodontitis, antimicrobial agents can be effective in controlling this condition. This study aimed to evaluate and compare the antimicrobial effects of coconut water and coconut oil on A. actinomycetemcomitans.
Materials and Methods: Coconut water was extracted by cracking a coconut and coconut oil was extracted by an oil-pressing machine by the cold pressing method at -50 ̊C. The disc diffusion test was carried out on 4 plates containing coconut oil, coconut water, positive control, and negative control to measure the diameter of growth inhibition zone. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined. All tests were repeated 3 times.
Result: Coconut oil in 100% concentration showed no antibacterial effect on A. actinomycetemcomitans in the disc diffusion test. Thus, the MBC and MIC were not determined for coconut oil. Coconut water demonstrated a bactericidal effect with 11, 9, and 0 mm growth inhibition zone diameter on 3 consecutive repetitions. According to independent t-test, a significant difference existed between the diameter of growth inhibition zone caused by coconut oil and positive control (P= 0.001).
Conclusion: Coconut oil showed no antibacterial effect on A. actinomycetemcomitans, and the antibacterial effect of coconut water on A. actinomycetemcomitans was very weak.

Abstract
Background and Aim: Stainless steel crowns (SSCs) are the gold standard for restoration of severely damaged primary teeth.
However, the unesthetic appearance of SSCs is responsible for their lower acceptance by clinicians and patients. Zirconia crowns areanother option for reconstruction of severely damaged teeth, which also provide optimal esthetics.
Case Presentation: Our patient was a 5-year-old child with acarious primary mandibular first molar. A prefabricated zirconia crown was considered for the tooth because the parents disapproved the color of SSC. The computer-aided design/computer-aidedmanufacturing (CAD/CAM) technology was used to fabricate azirconia crown with porcelain veneering since the size ofprefabricated crowns did not match the size of the respective tooth.
Conclusion: At the 1-year follow-up, the crown fabricated with this technique showed optimal esthetics, function, and durability.
Although these crowns have shortcomings such as the risk ofporcelain chipping, and require greater tooth preparation than SSCs, they can serve as a suitable alternative for reconstruction of severely damaged primary teeth when esthetics is an important parameter to consider. |
