In vitro effect of etching time and polymerization duration on the shear bond strengths to dentin

The effect of dentine etching time with H 3 PO 4 37% (20 and 60 sec) and composite polymerization duration (60 and 180 sec) on the shear bond strengths to dentin was evaluated in vitro. Dentine was treated with H 3 PO 4 37% in duration of 20 and 60 sec, before (Syntac ® ) was applied. The composite was polymerized for 60 and 180 sec. Data were analyzed with Anova and Tuckey test. Mean values for the first group (etching 20 sec / polymerization 60 sec) were 63.8 ± 3.7 N, for the second group (E 60 sec / P 60 sec) 111.7 ± 2.4 N, and for the third group (E 60 sec / P 180 sec) 132.8 ± 14.3 N. The control group (AdheSe ® ) had mean values 134.4 ± 15.5 N. There is significant difference found between the second and the first group (

The Association between Periodontal Disease and Preterm Low Birthweight in Kosovo

Svrha: U svijetu je visoka prevalencija parodontne bolesti. Dosadašnji dokazi podupiru stajalište da su gingivitis i parodontitis potencijalno infektivne bolesti i izvori upale koji mogu ugroziti fetoplacentarnu jedinicu. Cilj ovog istraživanja bio je usporediti parodontni status žena s normalnom i niskom porođajnom težinom djeteta. Ispitanici i metode: U istraživanje je bilo uključeno 200 rodilja te su analizirani njihovi parodontni i opstetricijski parametri. Parodontno stanje procjenjivano je u krevetu prema prilagođenim kriterijima Machteia, a tjelesna težina i gestacijska dob prema kriterijima Svjetske zdravstvene organizacije. Rezultati: Žene s parodontitisom statistički su 3,2 puta u većoj opasnosti da će roditi dijete niske porođajne težine i 3,4 puta da će roditi prije termina negoli žene bez te bolesti. Naime, takve žene imale su dublje parodontne džepove (2,49 mm ± 0,49 mm) od onih koje su rodile u terminu (2,26 mm ± 0,49 mm). Zaključak: Parodontološke bolesti kod trudnih žena, zato što su žarište mikroorganizama i njihovih produkata, mogu se smatrati rizičnim čimbenikom kad je riječ o neželjenom ishodu trudnoće.Objective: Periodontal diseases have a high prevalence worldwide. Existing evidence support the concept that gingivitis and periodontitis are potentially infectious and they present inflammatory reservoirs that can be threatening to the fetoplacental unit. The objective of this study was to compare the periodontal status between women with normal delivery and those with preterm low-birthweight delivery. Materials and Methods: This study included 200 postpartum women whose periodontal and obstetrical parameters were taken. The periodontal condition was assessed bedside according to the modified criteria established by Machtei, while the birthweight and gestational age were assessed according to the World Health Organization criteria. Results: Women with periodontitis are statistically at 3.2 times higher risk to deliver a child with low weight, and at 3.4 times higher risk to deliver preterm, compared to women without periodontitis. The women with preterm low-birthweight babies had deeper periodontal pockets (2.49mm ± 0.49mm) than women with normal delivery (2.26mm ± 0.49mm). Conclusions: Periodontal disease in pregnant women with a reservoir of organisms and their products can be considered a risk factor for adverse pregnancy outcome

Position of the Mental Foramen in Kosovarian Population

The aim of this study was to determine the position, shape, number and radiographic appearance of the mental foramen in a selected Kosovarian population. Five hundred panoramic radiographs of dental Kosovarian patients were selected and analyzed according to the mental foramen position, shape, radiographic appearance, number and symmetry. The mean distance in the horizontal plane of the mental foramen to the posterior border of the mandibular ramus was 67.5 mm and for distance from the mental foramen to symphysis menti 24.84 mm. In the vertical plane the mean distance of the mental foramen to alveolar crest was 20.38mmand 14.68mmfor distance of the mental foramen to the lower border of mandible. The majority of mental foramen was oval in shape and the most frequent radiographic appearance was the separated type. Accessory mental foramina were detected in <1% of the cases and the mental foramen was not bilaterally symmetrical but no statistical differences were found. This study showed that the most common position of the mental foramen investigated using panoramic radiographs from a selected group in Kosovarian population was between the first and second mandibular premolars with distinct tendency to be positioned near to the second mandibular premolar

Early childhood caries in preschool children of Kosovo - a serious public health problem

<p>Abstract</p> <p>Background</p> <p>Even though it has been widely studied, early childhood caries (ECC) remains a serious public health problem, especially in countries where there is no national program of oral health assessment and no genuine primary oral health care, such as in Kosovo. The purpose of this study was to assess the prevalence of ECC and analyze caries risk factors.</p> <p>Methods</p> <p>The subjects were 1,008 preschool children, selected by stratified random cluster sampling, in the municipality of Prishtina, capital of Kosovo. Data were collected through clinical examination and interviews. Dmft data were recorded according to WHO criteria. Bacterial examination (CRT bacteria test) and plaque test of Greene-Vermillion were used.</p> <p>Results</p> <p>The mean dmft of preschool children was found to be 5.8. The prevalence of ECC was 17.36%, with a mean dmft of 11 ± 3.6. Streptococcus mutans prevalence in ECC children was 98%. A significant correlation between dmft and S mutans counts (≥10⁵CFU/mL saliva) was demonstrated. A correlation was also found between daily sweets consumption and dmft in children with ECC (<it>P </it>< 0.001). Comparing the dmft of ECC children and duration of bottle feeding showed a statistical correlation (<it>P </it>< 0.001). The mean plaque test was 1.52. None of the examined children had ever used fluoride.</p> <p>Conclusion</p> <p>The prevalence of ECC was high among preschool children in the municipality of Kosovo. We recommend increasing parents' knowledge of proper feeding habits and oral health practices, and increasing preschool children's accessibility to dental services.</p

The Effect of Ca and Mg Concentrations and Quantity and Their Correlation with Caries Intensity in School-Age Children

Introduction. Saliva is a watery product formed by the salivary glands and secreted in the mouth. Besides the fundamental factors, saliva with its ingredient is one of the main etiologic factors of caries presence. In the development of dental caries, the relationship between demineralization and remineralization is influenced by the presence of saliva, which facilitates the transportation of ions, oral bacteria, and fermentable carbohydrates to the exposed surfaces of teeth. The main components of saliva electrolytes are sodium, calcium, copper, magnesium, bicarbonates, and organic phosphates. Increase in calcium level in the remineralization solution may enhance the deposition velocity of minerals in the caries lesion. Magnesium, except the similar role as calcium, takes an active part in cellular reparation process. Materials and Methods. In this study were included students of age 12-13. Students were divided into three groups; the first group included caries-free children, the second group with DMF = 1–6, and the third group with DMF > 6. Fully stimulated and nonstimulated saliva was collected in sterile graded patches in the morning hours, due to the circadian rhythm in 5-minute length. Chemical analyzes have been conducted at the Faculty of Chemistry, Ss. Cyril and Methodius University in Skopje. Statistical processing has been performed at the Medical Faculty, at the Institute of Medical Statistics in Skopje. Results. Depending on the DMF, before and after stimulation, regarding Ca level, no significant differences were found. However, the Ca level prior to stimulation is significantly higher in the second group compared to the third one. Also, the amount of Ca after stimulation in the first group was significantly higher. No significant differences in Mg level and amount were found prior to and after stimulation, while the amount of Mg after stimulation had a significant difference between groups. Conclusion. Saliva mineral analysis has shown significant differences in quantitative and qualitative components between examining groups. The decrease of calcium molality in saliva might play a significant role in caries occurrence; thus, we may suppose that saliva calcium level significantly influences hard dental tissues defense mechanism. Magnesium levels after stimulation showed a significant difference between groups I and III and no significant differences between groups I and II. Magnesium level and amount correlate with calcium level, favoring elemental caries resistance
