OBJECTIVE: This study evaluated the effects of fluoride varnishes containing sodium trimetaphosphate (TMP) on bovine enamel demineralization in vitro. MATERIAL AND METHODS: Enamel bovine discs were randomly assigned into six groups (n = 20/group): placebo, 2.5% NaF, 2.5% NaF/5% TMP, 5% NaF, 5% NaF/5% TMP, and a commercial formulation (Duraphat, 5% NaF). Varnishes were applied on all enamel discs and kept for 6 h. Loosely and firmly bound fluoride formed on/in enamel after treatment were analyzed in 10 discs from each group...

OBJECTIVE: To assess intended refusal of recent graduates from three Arab dental schools to treat HIV + patients and factors associated with this intention. MATERIALS AND METHODS: In 2015, convenience samples of recent dental graduates were included from Libya, Egypt and the United Arab Emirates. Participants responded to a questionnaire assessing personal background, knowledge of oral manifestations and fluids transmitting HIV, perceived adequacy of training and self-efficacy to manage blood exposures, attitude to risk of infection, moral beliefs and willingness to treat HIV + patients...

OBJECTIVE: Supernumerary teeth, a term describing a condition where patients have an abnormally large number of teeth, can be associated with non-syndromic or syndromic phenotypes. PDGFRs are cell surface tyrosine kinase receptors, and are involved in several aspects of tooth development. The purpose of this study was to identify causative genes of familial supernumerary teeth and the molecular pathogenesis of tooth number abnormalities through genetic analysis of a family that showed supernumerary premolars in two successive generations...

OBJECTIVE: This study aimed to compare sinus volume and dimensions in patients with high-, low-, and normal-angle vertical growth patterns using cone-beam computed tomography (CBCT). MATERIALS AND METHODS: According to skeletal vertical face growth patterns, 60 adults (31 female, 29 male, average age: 29.90 ± 10.91 years) were divided into three groups equally: high-angle, low-angle, and normal-angle groups. Cephalometric tracings were obtained from CBCT images and SN-GoGn (angle between Sella-Nasion line and Gonion-Gnathion line) cephalometric angular measurements used for the classification of skeletal vertical pattern evaluations...

OBJECTIVE: Cigarette smoking is associated with a variety of oral diseases. A previous study showed a reduction of thermal sensitivity in the innervation area of the lingual nerve in smokers possibly caused by a degeneration of thermosensitive receptors as a consequence of smoking. The current study investigates somatosensory changes in ex-smokers. MATERIALS AND METHODS: Sensory functions in innervation areas of lingual nerve were investigated in 40 ex-smokers by psychophysical means...

OBJECTIVE: The aim of this study is to investigate the behaviour of iPSc derived from dental stem cells in terms of initial adhesion, differentiation potential on differently surface-treated titanium disc. MATERIALS AND METHODS: iPSc derived from human gingival fibroblasts (hGFs) were established using 4-reprogramming factors transduction with Sendai virus. The hGF-iPSc established in this study exhibited the morphology and growth properties similar to human embryonic stem (ES) cells and expressed pluripotency makers...

OBJECTIVE: This study aimed to investigate the systemic antibiotic usage in the perioperative period of periodontal flaps and its relevance to the infection after surgeries through reviewing the papers of the last decade. MATERIALS AND METHODS: A search was conducted for the studies of randomized clinical trials between 2005 and 2014 that reported periodontal flaps in chronic periodontitis patients. Data were extracted and the rate of the systemic antibiotic use, the infection rate after surgeries and the number needed to treat (NNT) to prevent one infected case were calculated...

OBJECTIVE: To evaluate the effect of five sessions of cognitive behavioural therapy (CBT) for 10- to 16-year-olds with intra-oral injection phobia. MATERIAL AND METHODS: This was a randomized delayed intervention controlled trial in 67 patients, fulfilling the DSM-5 criteria for specific phobia. All patients received the same CBT performed by dentists specially trained in CBT. The patients were randomly assigned to either an immediate treatment group (ITG) (34 patients) or a waitlist-control group (WCG) (33 patients)...

OBJECTIVE: To investigate the effect of local hIL-10 gene therapy on experimental periodontitis in rats and to elucidate the mechanism underlying this effect. MATERIAL AND METHODS: Experimental periodontitis was induced in ovariectomized (OVX) rats using a silk ligature. We then injected 5 μg of hIL-10 plasmid with 5 μl of liposomes or 5 μg of vector plasmid with 5 μl of liposomes into the palatal side of the gingival mucosa of the upper left second molar once every two days...

OBJECTIVE: The parameters of orofacial dysfunction (OFD) in children can guide clinicians and researchers in the monitoring of deviations from normality. The aim for this study was to evaluate manifestation patterns and the prevalence of OFD in children. MATERIALS AND METHODS: A population-based cross-sectional study was conducted involving 531 schoolchildren (8-10 years old) in a small city in southern Brazil. OFD was evaluated using the Nordic Orofacial Test-Screening (NOT-S)...

OBJECTIVE: Our aim was to analyze longitudinally the impact of young children's dental general anaesthesia (DGA) treatment on their OHRQoL and to determine their post-operative oral health status at the six-month follow-up together with parental ratings of their children's oral health. MATERIAL AND METHODS: We conducted a prospective follow-up study of OHRQoL among Lithuanian child patients treated under general anaesthesia (n = 144). The study consisted of clinical dental examinations performed by two examiners at the time of DGA and at the six-month recall, along with OHRQoL surveys and data collected from the patients' files...

OBJECTIVE: Historically, it has been shown that rheumatoid arthritis (RA) and periodontitis (PE) share pathophysiological similarities and possibly a genetic background. In order to elucidate the genetic background between both diseases, we evaluated the distributions of five SNPs genotypes and all the possible haplotypes composed in subjects with isolated RA, PE, combined diseases and healthy controls. MATERIALS AND METHODS: The study population consisted of 280 Mexican subjects...

Nuria Nieto-Nieto, Jose Enrique Solano, Rosa Yañez-Vico
Root resorption is a pathological process of multifactorial origin related to the permanent loss of dental root structure in response to a mechanical, inflammatory, autoimmune or infectious stimulus. External apical root resorption (EARR) is a frequent clinical complication secondary to orthodontic tooth movement; apart from variables related to treatment, environmental factors and/or interindividual genetic variations can confer susceptibility or resistance to its occurrence. In this context, genetic predisposition has been described as an etiological factor, together with mechanical factors derived from orthodontic treatment...
