The Effect of Finishing and Polishing Techniques on the Surface Roughness and the Color of Nanocomposite Resin Restorative Materials.

Background: Rough, poorly polished surfaces contribute to staining, plaque accumulation, gingival irritation and recurrent caries. Finishing and polishing techniques are critical factors contributing to the longevity of the direct composite resin restorations.

Objectives: The aim of this in vitro study was to evaluate the effects of finishing and polishing systems on surface roughness of six nanocomposite restorative resins.

Oral findings of rothmund-thomson syndrome.

Rothmund-Thomson syndrome (RTS) is an extremely rare genetic condition exhibiting some dermatological, craniofacial, ophthalmological, and central nervous system abnormalities. It has an autosomal, recessive inheritance and its signs begin at childhood. Essential dermatological alteration is poikilodermatosis.

Effect of different topical fluoride applications on the surface roughness of a colored compomer.

Objective: The aim of this study was to evaluate the effect of neutral sodium fluoride (NNaF) gel and acidulated phosphate fluoride (APF) gel on the surface roughness of colored compomer (Twinky Star), conventional compomer (Compoglass F) and resin-modified glass-ionomer cement (RMGIC) (Photac-Fil).

Material And Methods: A total of 45 standardized disc-shaped specimens were prepared for each material. After 24 h, finishing and polishing of specimens were done with aluminum oxide disc.

Effect of radiotherapy on the microleakage of adhesive systems.

Purpose: The aim of this in vitro study was to evaluate the effect of radiotherapy on the microleakage of three adhesive systems: a one-step self-etching, a two-step self-etching, and an etch-and-rinse system.

Materials And Methods: Box-shaped Class V cavity preparations were prepared on the buccal surfaces of 84 extracted human molars. The molars were randomly assigned into 6 groups (n = 14) according to the irradiation and adhesive system as follows: G1, Clearfil S3 Bond (irradiated); G2, Clearfil SE Bond (irradiated); G3, Prime & Bond NT (irradiated); G4, Clearfil S3 Bond (nonirradiated); G5, Clearfil SE Bond (nonirradiated); and G6, Prime & Bond NT (nonirradiated).

Traumatic dental injuries in children with attention deficit/hyperactivity disorder.

The aim of this study was to assess the frequency and distribution of traumatic injuries in 247 children with attention deficit/hyperactivity disorder (ADHD) who were 7-16 years old and attended the Ondokuz Mayis University Medical Faculty (Department of Child Psychiatry, Samsun, Turkey). Each psychiatric diagnosis was based on criteria from the Diagnostic and Statistical Manual of Mental Disorders (4th edn, Washington, DC: American Psychiatric Association, 1994). Traumatic dental injuries were recorded using the classification of the World Health Organization, which was slightly modified by Andreasen and Andreasen (Textbook and color atlas of traumatic injuries, 3rd edn.

Traumatic tooth injuries to primary teeth of children aged 0-3 years.

The purpose of this study was to analyze data according to gender, age, cause, number of traumatized teeth, type of tooth and trauma, from the records of traumatized children (0-3 years) referred to the Ondokuz Mayis University, Dental Faculty, Department of Pedodontics in middle Black Sea region of Turkey. A total of 563 boys and girls participated in the study. Traumatic dental injuries were recorded using the classification of the World Health Organization modified slightly by Andreasen & Andreasen.

Can radiotherapy affect the apical sealing ability of resin-based root canal sealers?

Background: The authors conducted a study to assess the influence of radiotherapy on the apical sealing ability of one recently introduced resin-based root canal sealer and two sealers that have been in use for several years.

Methods: The authors divided 90 human maxillary anterior teeth into three groups according to the type of root canal sealer used and, using lateral condensation, obturated the roots with gutta-percha. They randomly divided all roots into two main groups according to the presence or absence of radiotherapy.

Evaluation of the relationship between passive smoking and salivary electrolytes, protein, secretory IgA, sialic acid and amylase in young children.

Objective: To evaluate the relationship between passive smoking as determined by salivary cotinine levels and salivary electrolytes, protein, secretory IgA, sialic acid and amylase in children.

Design: Saliva was collected from 90 passive smoker (PS) subjects (the study group) and 90 healthy age-matched children (the control group). The study group was divided into three subgroups according the number of cigarettes smoked.

Efficacy of dental practitioners in injection techniques: computerized device and traditional syringe.

Objective: To compare the effect of clinicians on the behavioral pain reaction of children who received local anesthesia with a conventional technique and a computerized device (Wand, Milestone Scientific).

Method And Materials: One hundred four children aged 6 to 12 years who needed operative dentistry using infiltrative anesthesia in the mandible and maxilla were selected for this study. The patients were divided into 2 groups, each assigned to a different clinician, and received anesthesia either by the Wand or conventional technique.

The presence and distribution of dental enamel defects and caries in children with celiac disease.

The aim of this study was to investigate the presence and distribution of developmental enamel defects and caries in children with celiac disease (CD) and compare the results obtained with those of a control group of children without CD. A total of 64 subjects (mean age 8.2 years) selected from patients diagnosed and treated for CD were studied.

Long-term effects of chemotherapy on caries formation, dental development, and salivary factors in childhood cancer survivors.

Objective: The aim of this study was to investigate the long-term effects of chemotherapy on oral health and dental development in childhood cancer survivors (CCS).

Study Design: Ninety-six CCS patients with a mean age of 10.8 years and 96 healthy children of the same age and sex and social background composed the study group.

Dental findings in a child with glycogen storage disease type IA.

Glycogen storage disease type I, also known von Gierke's disease, is a rare, severe autosomal recessive disorder due to a defect in liver, kidney, and intestinal mucosa. The existence of delayed development of the dentition, increased incidence of dental caries, taurodontism, and prolonged bleeding following dental procedures should lead clinicians to consider type I glycogen storage disease. A 10-year-old boy with glycogen storage disease type I whose condition was first diagnosed when he was 4 years of age, was referred to the clinic for multiple caries and evaluation of delayed tooth eruption.
