Determination of the ecological status of an Aegean river (Türkiye) using benthic macroinvertebrates as an indicator of water quality.

Bakırçay is one of the important rivers of Western Anatolia, Türkiye. The objectives of this study are (a) to determine the diversity of benthic invertebrates distributed in Bakırçay, (b) to evaluate the obtained data using various biological indices, (c) to determine the interactions of species with environmental variables, and (d) to estimate the water quality level of the river using BMWP and ASPT analyses. Samplings were carried out at 15 stations between October 2017 and July 2018, seasonally.

On the molecular and morphological evolution of continental and insular species, with an additional description of (Talitridae).

Semi-terrestrial talitrid amphipods of the genus (sensu Lowry and Fanini 2013) associated with freshwater-soaked leaf litter were known to occur in inland lakes of Turkey and at the shores of the Black Sea. Before 2013 they had been reported as and later as . In our phylogenetic tree, inferred from a mitochondrial and nuclear gene dataset (cytochrome oxidase I (COI), and histone H3 (H3), respectively), we show that these Turkish populations belong to , a common and widespread continental species, which is closely related to (endemic to Cyprus) and (endemic to Rhodes).

[Terminology and classification of condylar hyperplasia: Two case reports and review].

Condylar hyperplasia is characterized by the growth of mandibular condyle. Its etiology and pathogenesis remain controversial. It often occurs unilaterally and leads to facial asymmetry and malocclusion.

The influence of platform switching on clinical, laboratory, and image-based measures: a prospective clinical study.

Purpose: This prospective study was conducted to compare the marginal bone level alterations, stability/mobility measurements, and volume of myeloperoxidase (MPO) and nitric oxide (NO) of peri-implant sulcus fluid (PISF) between platform-switched (PS) and standard platform (SP) implants inserted to mandibular premolar/molar regions with a single-stage protocol.

Materials And Methods: Thirty-two (16 PS and 16 SP) implants restorated with fixed prosthesis were included in the study. For both implant systems standard implant dimensions were used.

Application of Kvaal et al.'s age estimation method to panoramic radiographs from Turkish individuals.

Age estimation of living adult individuals can be accomplished with limited methods. Radiographic dental methods based on the pulpal narrowing with secondary dentin formation have been presented. In the present study, Kvaal et al.

Oral health status in a group of the elderly population residing at home.

Objectives: To determine the oral health status and treatment needs of subjects aged 65 years and older residing in different districts of Ankara.

Materials And Methods: A total of 1300 patients, 751 females and 549 males, age 65 and over with a mean age of 72.8 ± 6.

Morphological evaluation of rat incisor enamel and dentin induced by pregnancy and lactation using a scanning electron microscope.

This study assessed the effects of pregnancy and lactation on the morphology of the dentine tubules and external enamel surface of rat incisor teeth using a scanning electron microscope (SEM) equipped with an energy dispersive x-ray (EDX) system. Twenty-four female Wistar rats were divided into three groups; group A rats were at the end of pregnancy, group B rats were in the post-lactation period and group C rats, the control group, were unmated. The outer enamel surface and openings of the dentine tubules at the neck regions of the incisors were observed under the SEM and photographed.

Stability of maxillary expansion and tongue posture.

Objective: To evaluate the adaptive changes and the stability in tongue posture following rapid maxillary expansion (RME) in patients without any signs or symptoms of respiratory disturbances.

Materials And Methods: Growing subjects with maxillary constrictions and bilateral buccal crossbites were included in the treatment group (n = 20). A control group (n = 20) comprised subjects with normal dentoskeletal features.

Oral trauma, mouthguard awareness, and use in two contact sports in Turkey.

The purpose of the present study was to evaluate the occurrence of dental hard and soft tissue injuries during participation in contact sports, and the awareness and use of mouthguards in a young adult sample of semi-professional or amateur boxers and tae kwon do participants in Turkey. The samples consisted of 274 young adults [174 male (63.5%) and 100 female (36.

Evaluation of mandibular bone density to predict osteoporosis in adolescents with constitutional delayed growth.

Objective: The aim of this study is to evaluate the correlation between constitutional delayed growth (CDG) and mandibular bone trabeculation as well as bone density on panoramic radiographs using a computer software program.

Methods: Panoramic radiographs obtained from 25 patients with CDG and 25 healthy adolescents were evaluated for this study. Patients were selected from admission to Hacettepe University, Faculty of Medicine, Section of Adolescent Medicine in the first half of the year 2002.

Oral findings and health status among hospitalized patients with physical disabilities, aged 60 or above.

The purpose of the study was to determine oral health status and the prevalence of oral mucosal lesions among hospitalized elderly patients with physical disabilities. The study group consisted of 111 (43 male and 68 female) elderly patients with physical disabilities. Clinical examination and interview methods were employed.

Effects of pregnancy and lactation on the microhardness of rat incisor dentine and enamel.

Pregnancy and lactation affect the rate of maternal dentine apposition and mineralization in the rat. In this study we have measured the effects of pregnancy and lactation on the degree of mineralization of dentine and enamel by using the microhardness method in rat incisors. At incisal sections, pregnant and lactation group enamel values were increased compared to that of a control group; the pregnancy and post-lactation period dentine values decreased slightly compared to the control group.

Bifid mandibular condyle: a case report.

A case of left bifid mandibular condyle (BMC) is reported in a 36-year-old female. The patient had a history of trauma in childhood. From the radiological examination, the left condyle was seen to have two anterioposteriorly situated heads.

A study of the dental solid waste produced in a school of dentistry in Turkey.

Dental wastes are regulated under medical waste control regulations in most countries. Even though the quantity of hazardous wastes in dental solid wastes is a small proportion, there is still cross infection risk and potential danger for environment associated with mismanaged wastes. For this reason, knowledge of waste composition and development of proper management alternatives are necessary.

Accidental sodium hypochlorite-induced skin injury during endodontic treatment.

A case of accidental skin injury caused by leakage of sodium hypochlorite solution from the rubber dam during root canal preparation is reported. After placement of a rubber dam and initiation of root canal treatment, the patient complained of a burning sensation with sodium hypochlorite irrigation. The complaints were ignored by the practitioner, and a skin rash developed on and around the patient's chin, followed by scab formation.

Repair of untreated horizontal root fracture: a case report.

We report a clinical case of horizontal root fracture in the mandibular first premolar induced by a traffic accident. The fractured tooth spontaneously healed and diagnosed radiographically after 2 years. Fractured fragments were separated by a narrow radiolucent line and the edges were rounded, and healing of the tooth is likely to be related to interproximal connective tissue healing.

Evaluation of articulation of Turkish phonemes after removable partial denture application.

In this study, the adaptation of patients to removable partial dentures was evaluated related to articulation of Turkish phonemes. Articulation of /t,d.n,l,r/, /g,k/, /b,p,m/ and /s,z,ş,v,f,y,j,h,c/ phonemes were evaluated by three speech pathologists, on records taken from 15 patients before the insertion of a removable partial denture, just after insertion, and one week later.
