Restoring Aesthetics and Function in a Young Boy with Hypomature Amelogenesis Imperfecta: A Case Report

Amelogenesis imperfecta has been described as a complex group of inherited conditions that disturbs the developing enamel structure and exists independent of any related systemic disorder. It is a rare dental disease but represents a great restorative challenge for dentists. A 12-year-old boy presented with sensitive, discolored, and mutilated teeth and decreased vertical dimension of occlusion. Direct composite resin restorations were applied to all teeth to modify the occlusion, to restore mild crowding, and to improve aesthetics. The 24-month recall examination revealed no pathology associated with the rehabilitation, and the patients aesthetic and functional expectations were satisfied. The rehabilitation included multiple anterior and posterior composite resins to eliminate tooth sensitivity, improve the aesthetics and occlusion, and restore function.

The Detailed Evaluation of Supernumerary Teeth with the Aid of Cone Beam Computed Tomography

ABSTRACT The aim of this paper is to demonstrate the application of a recently developed three-dimensional imaging system, cone beam computed tomography, in the detailed evaluation of supernumerary teeth. Two-hundred and twenty three patients with supernumerary teeth (68 females and 155 males) were included in this study. Patients ranged in age from 12 to 25 years. Supernumerary teeth were detected by clinical examination and traditional radiographies. Moreover, careful investigation for more details was made with the cone beam computed tomography. Supernumerary teeth which were detected with the examinations of the cone beam computed tomography images were classified according to the number, location, shape and eruption rate. The prevalence of supernumerary teeth was determined to be 1.45% of the study population. Males were affected more than females in a ratio of 2.3:1. Supernumerary teeth were most frequently located in 86.2% of the cases in the maxilla; 10.1% in the mandible and 3.7% both in the maxilla and mandible. Supernumerary teeth were most commonly conical in shape (68.8%). One supernumerary tooth was present in 67.7% of the patients, 30.9% had two, and 1.4% had three supernumeraries. Definite and early diagnosis of the supernumerary teeth is very important. Detailed examinations and evaluations of these teeth with three-dimensional images is very benefical in terms of treatment planning and preventing complications which may occur.

Comparison of Apical Microleakage of Dual-Curing Resin Cements with Fluid-Filtration and Dye Extraction Techniques

Background Endodontically treated teeth with excessive loss of tooth structure are frequently restored using fiber posts. In this in vitro study, the apical leakage of self- and dual-activated curing modes for dual-curing resins cementing a translucent fiber post was evaluated using computerized fluid filtration meter and dye extraction method. Material/Methods One hundred and four extracted human maxillary incisors with single root and canal were used. Experimental samples embedded in a closed system were divided into 4 groups (n=20) according to 2 dual-curing luting systems, with 2 different curing modes (either with self- or light-activation): (1) Panavia F 2.0 with self-cure, (2) Panavia F 2.0 with light-activation, (3) Clearfill SA with self-cure, and (4) Clearfill SA with light activation. Twenty-four teeth served as negative and positive controls. Translucent fiber posts were luted in the roots except in the control groups. Results Statistical analysis indicated no significant difference in leakage among groups (p>0.05) with 4.12×10−4 (Panavia self-cure), 4.55×10−4 (Clearfill SA self-cure), 5.17×10−4 (Panavia dual-cure), and 5.59×10−4 (Clearfill SA dual-cure) in fluid-filtration method. Absorbance values for dye-extraction method were 266 nanometer (nm) (Panavia self-cure), 268 nm (Clearfill SA self-cure), 270 nm (Panavia dual-cure), and 271 nm (Clearfill SA dual-cure), in which difference among the groups were not statistically significant (p>0.05). When comparing the leakage, assessment methods results showed no statistically significant difference between the tested evaluation techniques (p>0.05). Conclusions Light- and self-activation curing modes of Panavia F 2.0 and Clearfill SA perform similar to each other in a closed system.

Clinical Presentation and Management of Ectodermal Dysplasia

ABSTRACT This article reviewed the clinical and radiologic aspects of ectodermal dysplasia as well as the dental treatment, and describe the oral rehabilitation. Patients with this disease often need complex dental treatment. The options for a definitive treatment plan may include fixed, removable, or implant-supported prostheses, singly or in combination. This clinical report describes the diagnosis and treatment of ectodermal dysplasia in the six patients (three males and three females, aged 9 to 22 years) with ectodermal dysplasia. Ectodermal dysplasia patients had a clinical examination and they had undergone radiographic and Steiners analysis, and respiratory capability test before being assessment and treated. The prosthodontic treatment included interim removable partial dentures fabricated to establish an acceptable therapeutic occlusal vertical dimension, followed by definitive overlay removable partial dentures. As a result comprehensive and multidisciplinary team approach necessary to these patients for improve their dental, masticatory, growing, and orthognathic conditions.
