Ortodontik tedavi sonrası pekiştirme aşamasının hasta perspektifinden değerlendirilmesi

Amaç: Bu çalışmanın amacı sabit ortodontik tedavi görmüş hastaların tedavi sonrası pekiştirme aşamasının hasta perspektifinden değerlendirilmesidir. Gereç ve Yöntem: Bu araştırma Google formlar programı kullanılarak 20 tane anket sorusunu doldurmayı kabul eden 8-18 ve >18 yaş arasındaki 100 hasta üzerinde gerçekleştirilmiştir. Hastaların verdikleri cevaplar doğrultusunda hastaların ortodontik tedavi sonrasında nüks hakkında bakış açıları değerlendirilmiştir. Elde edilen veriler cinsiyet, yaş, eğitim durumu, tedavi şekli gibi kriterlere göre SPSS 21 paket programı aracılığı ile analiz edilmiştir. Değişkenler arasındaki ilişkiye/bağımlılığa ki-kare analizi ile bakılmıştır. Bulgular: Ortodontik tedavi sonrası dişlerinde bozulma olmadığını düşünen bireylerin %96’sında lingual retansiyon apareyi yapılmıştır. Retansiyon apareyi kırılan hastaların %83.3’ü dişlerinde orta şiddette bozulma olduğunu bildirmiştir (p<0.001). Ortodontik tedavi sırasında braketi kırılan hastalar ile tedavi sonrasında orta şiddette bozulma olması arasında anlamlı bir bağlantı bulunmuştur (%70). Dişlerindeki bozulmayı düzeltmek için şeffaf plak tedavisini kadınlar (%85.7), erkeklere oranla daha fazla tercih ettiğini bildirmiştir (p<0.05). Sonuç: Ortodontik tedavi sonrası pekiştirme aşamasındaki başarı, hasta kooperasyonu ile bağlantılı olabilir. Çalışmamızda nüks olan hastaların ikinci ortodontik tedavilerde sabit tel tedavisi yerine şeffaf plak tedavilerini tercih ettiği görülmüştür

Effect of salvianolic acid B on new bone formation in the orthopedically expanded suture: A histological and immunohistochemical study

Objectives: To determine the effects of Salvianolic acid B (Sal B) on new bone formation in the orthopedically expanded premaxillary sutures in rats.Materials and Methods: The sample consisting of Sprague Dawley rats (male, n = 14) was split in half by random selection: the experiment group (Sal B) and the control group. The premaxillary suture of each rat was expanded by bonding an open-loop spring to two maxillary incisors, each end to one tooth. A 5-day expansion period followed by a 12-day retention period was conducted. The 17-day intraperitoneal administration of Sal B was performed daily for the experiment group at a dose of 40 mg/kilo. The trial was completed after sacrificing the rats and dissection of the premaxillae for histological analysis. The amount of new bone, quantity of capillaries and intensity of inflammatory cells were histomorphometrically determined while the quantities of osteoblasts and osteoclasts were determined immunohistochemically.Results: The Sal B group was significantly different from the control group and had greater quantities of new bone, capillaries, inflammatory cells, osteoblasts, and osteoclasts.Conclusions: Salvianolic acid B displays a positive effect during premaxillary expansion with a greater number of capillaries potentially in association with higher bone formation and improved angiogenesis in rats.Scientific Research Projects Commission (BAP) of Anadolu University (Eskisehir, Turkey

Comparison of tooth-borne and hybrid devices in surgically assisted rapid maxillary expansion: A randomized clinical cone-beam computed tomography study

Purpose: The objective of this 2-arm, parallel, single-center trial was to compare the skeletal, dental, and periodontal effects of tooth-borne (TB) and hybrid devices in surgically assisted rapid maxillary expansion (SARME)

Skeletal, dentoalveolar, and buccal bone changes using hybrid and tooth-borne expanders for RME and SARME in different growth stages

To compare the skeletal, dentoalveolar and buccal bone thickness of tooth–bone-borne (Hybrid-H) and tooth-borne (TB) maxillary expanders used for rapid maxillary expansion (RME) in early and late adolescents and for surgically-assisted RME (SARME) in young adults

New bone-generative effect of Salvia officinalis L. in the expanded midpalatal suture An in vivo and in vitro study

Purpose The aims of this study were to evaluate the effects of systemic administration of Salvia officinalis Linnaeus (L.) leaf extract on new bone formation in the expanded premaxillary suture in rats in vivo and to examine the antioxidant effects and phenolic profile of Salvia officinalis (SO) leaf and root extracts in vitro. Methods Fourteen male Sprague Dawley rats were allocated to two groups: SO group (n = 7) and control group (n = 7). An open-loop spring was attached to the upper incisors of each rat to expand the premaxillae. A 5-day expansion period followed by a 12-day retention period was observed. The rats in the SO group received systemic administration of 20 mg SO/kg/day via the orogastric route for 17 days. Histomorphometric examinations were carried out to examine the amount of new bone formation, number of capillaries, and intensity of inflammatory cell response. Immunohistochemical analysis was conducted to examine the number of osteoblasts and osteoclasts. Leaf and root extracts of SO were also analyzed for antioxidant activity and phenolic compounds in vitro. Results Statistical analysis showed that the following were higher in the SO group than in the control group: new bone formation, number of osteoblasts and osteoclasts, intensity of inflammatory cell response (neutrophils, lymphocytes, and macrophages), and number of capillaries. The major compound identified in SO leaf extract was rosmarinic acid, while luteolin derivatives, salvianolic acid F, and medioresinol were also present. Conclusions Salvia officinalis L. from leaf extract provided antioxidant effects and stimulated enhanced new bone formation in the expanded midpalatal suture after maxillary expansion in rats.Scientific Research Projects Commission (BAP) of Anadolu Universit

Nasal soft- and hard-tissue changes following tooth-borne and hybrid surgically assisted rapid maxillary expansion: A randomized clinical cone-beam computed tomography study
