Ordu ve Çevresinde Yayılış Gösteren Trachystemon orientalis (L.) G. Don (Boraginaceae) Türünün Bazı Mikromorfolojik Özellikleri ve Tüy yapısı

Trachystemon orientalis türünün gövde, yaprak, kaliks, korolla ve meyve yüzeyleri ve tüy yapısı mikromorfolojik olarak incelenmiştir. Türde beş tanesi örtü tüyü, 3 tanesi salgı tüyü olmak üzere sekiz çeşit tüy bulunmaktadır. Tüyler tek hücreli veya çok hücrelidir. Türün yaprak üst ve alt yüzeyi dalgalı epidermis hücrelerine sahiptir. Yaprak amfistomatiktir. Alt yüzeyde stomalar çok daha yoğundur. Stomalar genellikle epidermis hücreleri ile aynı seviyededir. Stoma porları dar ve uzundur. Meyve nutlet tipidir. Meyve yüzeyi tüberkulat tiptedir.

Composite Mesiodens with Impacted Conical Mesiodens: A Case Report

Supernumerary teeth are a relatively frequent disorder of odontogenesis characterized by an excess number of teeth. Mesiodens is the most common type of supernumerary tooth found in the premaxilla between the two central incisors. They can be supplemental (resembling natural teeth), conical, tuberculate or molariform. This paper presents a rare, clinically rotated multi-lobed tuberculate type of mesiodens which was associated with another impacted conical mesiodens in a 10 year-old girl.

Tuberculate and Odontoma Type Supernumerary Teeth

An 8-and-a-half-year-old girl with supernumerary teeth of tuberculate and odontoma type is described. Treatment of the patient is carried out on conventional lines with a combination of surgical and orthodontic methods. The upper tuberculate type supernumerary teeth were extracted and, after surgical exposure, the upper permanent first incisors were aligned with removable appliances. After secondary dentition was completed, the lower odontoma type supernumerary tooth was removed surgically, and also the maxillary and mandibular first premolars were extracted because of severe crowding, and fixed orthodontic appliances were used to align the permanent dentition. Early diagnosis and treatment of this anomaly is necessary to avoid more serious consequences and to prevent severe orthodontic disturbances.

Supernumerary teeth: review of the literature and a survey of 152 cases.

A review of the literature relating to supernumerary teeth is presented along with a survey of 152 cases. The study population consisted of 152 children who visited the department of Paediatric Dentistry at the Jordan University Hospital. Patients ranged in age from 5 to 15 years. Supernumeraries were detected by clinical examination and radiographs. Males were affected more than females with a sex ratio of 2.2 : 1. Seventy-seven percent of the patients had one supernumerary tooth, 18.4% had double teeth, and 4.6% had three or more supernumeraries. Ninety percent of the supernumerary teeth occurred in the premaxilla, of which 92.8% were in the central incisor region and of these latter 25% were located in the midline. The other 10.4% of the supernumeraries were located in the premolar, canine, molar, and lower central incisor regions. Two cases were of non-syndrome supernumerary teeth. Seventy-five percent of the supernumeraries were conical, 83.1% were in the normal vertical position and 26.5% were erupted. Conical-shaped supernumerary teeth had a significantly higher rate of eruption compared to the tuberculate type.

Trichomes of the genus Alyssum L. (Cruciferae) in Jordan

Summary Trichome types of 12 species of the genus Alyssum in Jordan have been studied, by the aid of light and scanning electron microscope (SEM). 16 types of trichomes were recognized. Scales, and unicellular eglandular hairs ranging from sessile of double bifurcate or multibranched webbed or un-webbed type with inflated or flat centre of 3–5 primary branches. Stalked bifurcate, tuberculate and multibranched glabrous or tuberculate types have also been recorded. The hair types recognized in this study provided useful taxonomie evidence that can be used to identify the different taxa of Alyssum.

Üst Orta Keserlerinde indifa gecikmesi olan bir vak'anın tedavisi

SUMMARY In this article, treatment of a case of unerupted central incisors delayed in their eruption by supernumerary teeth has been reported. It appears that there are differences between supernumerary teeth in their time of development, their position and their efect on the eruption of the associated permanent upper central incisors. There are different types of supernumerary teeth occuring in the upper central incisor region. The tuberculate type considerably delays the eruption and its usual position palatal to the permanent upper central incisors. Root formation seems to be later in its development than the conical type and the permanent upper central incisors. The conical type is not usually delays the eruption of the permanent upper central incisors.
