Research is needed to better understand the perception of dental pain in comparison with pain in other organs. To investigate relations between the perceptions of dental and somatic pain complaints among school-age children. One hundred and two children, aged 7–17 years (mean age, 11.5 ± 2.65 years), completed questioners regarding their somatic and dental: 1. Memory pain rank (MPR) and 2. Wong-Baker FACES Pain Rating Scale (FRS). Children reported increased dental pain after school

in both scales (P = 0.015 in MPR). In both MPR and FRS, the pattern of pain ranking was similar: Abdominal pain was scored highest (2.75 ± 1.4 and 1.56 ± 1.63, respectively), followed by headache, ear, dental and TMJ (Temporomandibular joint). There was a strong correlation between pain perception and current pain scores in every organ. Somatic

pain, namely head, abdomen PD-0332991 ic50 and ears, was ranked selleck products significantly higher than dental and TMJ pain. School-aged children rank current pain and pain experience significantly lower while they are pre-occupied (school time) in comparison with times when they are less busy (after school time). “
“International Journal of Paediatric Dentistry 2012; 22: 356–362 Background.  In a randomized double-blinded clinical trial, preschool children used sucrose or xylitol chewing gum regularly for 2 months to study the preventive effect of xylitol on acute otitis media (AOM). Salivary mutans streptococci (sm) levels of the children were measured before the exposure. Those with ≥105sm CFU in 1 mL saliva were considered

to have high sm levels (sm+); and those with <105 CFU low sm levels (sm−). Aim.  This practice-based study aims to evaluate long-term dental effects of the sucrose/xylitol exposure on primary teeth. Design.  For analyses, individuals were divided into sub groups according to their study group in the original AOM trial and baseline sm levels. Outcome Mephenoxalone events owing to dental caries of their all primary teeth were followed from dental records up to 12 years. Survival of teeth caries free was determined by Kaplan–Meier method and analysed statistically by Wilcoxon testing. Results.  Survival of primary teeth caries free of children with high sm levels in the sucrose group was significantly shorter compared with all other groups when followed until shedding. Conclusions.  Two months’ regular exposure to sucrose was sufficient to induce dental caries in primary teeth of children with elevated sm levels at baseline. “
“International Journal of Paediatric Dentistry 2011; 21: 314–320 Background.  Adhesive procedures are often required to restore teeth affected by hypocalcified amelogenesis imperfecta (HAI). Aim.  To evaluate the hardness of enamel/dentin of teeth affected by HAI and the bond strength to these substrates, as well the influence of 5% NaOCl on bond strength. Design.  Permanent molars presenting HAI and sound third molars were used. Enamel surfaces were wet-flattened and Knoop hardness was assessed.
