Treatment of a patient with amelogenesis imperfecta (AI) presents a real problem from both functional and esthetic points of view. An esthetic result also will result in an improvement in the patient's quality of life. This clinical report illustrates the oral rehabilitation of a 24-year-old man diagnosed with hypomature type of AI. The aim of treatment was to both restore esthetics and improve masticatory function. Esthetic expectations of the patient were successfully attained by placing all-porcelain crowns from canine to canine in each arch, 12 crowns total. Moreover, metal-ceramic three-unit fixed partial dentures for the missing mandibular right first molars were fabricated for the patient's masticatory function. Resin composite restorations were applied to the maxillary premolars, the maxillary right first molar, the mandibular left premolars, and the right first premolar to modify the occlusion. No deterioration in the restorations and no pathology associated with the rehabilitation were found at the 1-year recall, and the patient's esthetic and functional expectations were satisfied. CLINICAL SIGNIFICANCE This article provides an overview of an interdisciplinary approach to treating the difficult condition of AI using a combination of treatments to achieve optimal esthetics and function.

Sleep bruxism, which heavily depends on self-report, is significantly associated with TMD. Unilateral chewing seems to be a common factor for development of SB and TMD. However, further studies are needed to corroborate this finding. Additionally, this study supports the hypothesis that occlusal factors are not related to self-reported sleep bruxism.

It can be concluded that HS inhalation equivalent to pathologic halitosis producing level in humans may lead to systemic effects, particularly heart or liver damage in rats.

Bruxism is a repetitive jaw muscle activity characterized by grinding or clenching of the teeth and/or by bracing or thrusting of the mandible. There are two types of bruxism: one that occurs during sleep (sleep bruxism) and one during wakefulness (awake bruxism). 1 While there is no consensus on the exact cause of sleep bruxism (SB), current literature support the hypothesis that SB has a multifactorial etiopathogenesis which potentially involves disturbance of the dopaminergic system in the central nervous system, ÖZ Belli eğitim disiplinleri sigara alışkanlığı ve/veya muhtemel uyku bruksizminin gelişiminde bir risk faktörü müdür? Üniversite öğrencilerinde bir çalışma Amaç: Bu çalışmanın amacı farklı eğitim disiplinlerinde öğrenim gören üniversite öğrencilerinde, eğitimin sigara alışkanlığı ve muhtemel uyku bruksizmi eğilimine olan etkisini ve varsa sigara ve muhtemel uyku bruksizminin ilişkisini değerlendirmektir. Gereç ve Yöntemler: Çalışma, Cumhuriyet Üniversitesi Diş Hekimliği Fakültesi Ağız, Diş ve Çene Radyolojisi Anabilim Dalı'na 2012-2014 tarihleri arasında başvuran, 17-34 yaş aralığında 262'si kız (%57) ve 195'i erkek (%43) olmak üzere 457 üniversite öğrencisinin doldurduğu formlar üzerinden retrospektif olarak yürütüldü. Bu formlarda öğrencilerin sorulara verdikleri cevaplar kaydedildi. Bulguların istatistiksel değerlendirilmesi SPSS 20.0 programında ki-kare analizi kullanılarak yapıldı. Bulgular: Sigara alışkanlığı mühendislik bölümü öğrencilerinde ve erkeklerde anlamlı derecede yüksek bulundu (p<0.05). Sigara kullanan öğrencilerde muhtemel uyku bruksizmi görülme sıklığı yüksek olsa da bu fark anlamlı değildi (p>0.05). Cinsiyet ve eğitim disiplinlerinin muhtemel uyku bruksizmiyle arasında anlamlı bir ilişki yoktu (p>0.05). Sonuç: Eğitim disiplinlerinin sigara alışkanlığında etkisi bulunurken, muhtemel uyku bruksizmi üzerinde bu etki görülmemiştir.

Objectives: To assess differential effects of different materials combined with allograft on bone-to-implant contact and newly formed bone formation in dental implants with coronal defects histomorphometrically. Materials and Methods: The study was conducted on 24 male New Zealand white rabbits. Dental implants (3.0 × 10 mm) were placed at the center of defects (9 mm diameter, 4 mm depth) created in the tibial bones of the rabbits. Graft (GF, n=8), graft + rifamycin (GR, n=8) and graft + black cumin oil via orogastric route (GB, n=8) were applied on the coronal aspects of the implants for 28 days. Undecalcified histomorphometric analyses were conducted on slides stained with toluidine blue. Results: Bone-to-implant contact was 46.57% ± 3.59% in the graft (GF), 67.12% ± 3.64% in the graft + rifamycin (GR) and 55.62% ± 4.37% in the graft + black cumin oil (GB) groups. The percentage of new bone formation at the defect area was 34.71% ± 4.11% in the graft, 55.37% ± 4.89% in the graft + rifamycin, and 45.75% ± 3.69% in the graft + black cumin oil groups. In terms of new bone formation and bone-to-implant contact, graft + rifamycin and graft + black cumin oil groups were significantly different from the graft group. The differences between the graft + rifamycin and graft + black cumin oil groups were also statistically significant. Conclusions: Allograft + rifamycin and orogastric black cumin oil were found to have positive effects on bone healing at sites with coronal defects. Rifamycin showed significantly greater favorable effects on bone-to-implant contact and new bone formation compared to black cumin oil.
