effect of treatment with carbamide peroxide and hydrogen peroxide in patients affected by dental fluorosis

Dentalfuorosis is an endemic dental health problem around the world so, it is important to develop clinical alternatives that are non-invasive and inexpensive. In this study, nightguard vital bleaching technique [NVBT], using carbamide and hydrogen peroxide as active agents, has shown itself to be effective in whitening teeth effected by dental fluorosis. Carbamide peroxide at 10 and 20% and hydrogen peroxide at 7.5% showed good clinical effectiveness in improving clinical appearance, but it is important to point out that clinical success is only in cases of class 1 to 3 of the Tooth Surface Index of Fluorosis. When comparing 10 and 20% concentrations of carbamide peroxide, there was no difference in the clinical effectiveness [p>0.05]; but when comparing both concentrations of carbamide peroxide against hydrogen peroxide, results showed that carbamide peroxide, there was no difference in the clinical effectiveness [p>0.05]; but when comparing both concentrations of carbamide peroxide against hydrogen peroxide, results showed that carbamide peroxide was more effective in whitening in cases of dental fluorosis, the difference being statistically significant [p<0.05]. NVBT has two advantages: it is a non-invasive technique and the relationship cost/benefit is excellent; only a few patients reported tenderness or mild tooth sensitivity

Comparison of two restorative techniques of posterior composite restoration in primary molars: an in vivo study

This in vivo study evaluated the clinical performance of class II restoration, in primary molars after 12 months. Two restorative techniques were used: filling the cavities in bulk and Oiling with three horizontal increments. The composite resin used was Prisma TP.H [Caulk - Dentsply] with the adhesive system Scotch- bond Mulipurpose [3M] Initially 80 class II restoration were placed in 25 patients from 7-9 years of age and followed - up for 12 months. After this period 39 restorations were evlauated for anatomic form, color alterations at the margin, presence of decay and marginal adaptation. The result showed that all groups presented similar rates of wear, the hulk insertion technique showed better results for marginal adaptation, color alterations of the margins and less presence of caries at occlusal margins, and that composite resin TP.H could be used as restoration in primarymolars

Effective oral doses of midazolam for anxious pediatric dental patients

A need exists for a safe and effective sedation for use children undergoing elective operative procedures. We evaluated the effectiveness of the different doses of oral midazolam in a randomized, double-blind, placebo- controlled study 132 children ages 5-10 years received 0.2 5, 0.50 or 0.75 mg.kg mixed with apple juice a placebo. A blinded observer noted the child's behavior and level of sedation the quality of separation from the parents and the degree of cooperation with an inhalation induction of anesthesia. Picture recall was used to assess the amnesic effect of midazolam in children. We concluded that oral midazolam 0.75 mg.kg is an effective sedation for pediatric dental outpatients

Relation between palmar plantar hyperkeratosis and aggressive periodontitis in Egyptian children

Aggressive periodontitis describe three of the diseases formally classified as early onset of periodontitis as localized juvenile periodontitis, generalized juvenile periodontitis and rapidly progressive periodontitis. This study was conducted oil children with age range from seven to fifteen years while mean age was 10.2. Fifteen boys and fifteen girls. Five of them were having Papillon - Lefevere syndrome [group I], tell had only ectodermal dysplasia [group II] and the rest of the children were normal healthy children with no obvious systemic disease [group III]. All the children undertaken medical and dental history. Complete dental examination and basic periodontal examination [BPE] were conducted using WHO probe. Mobility and furcation involvement were also measured to detect any sign of aggressive periodontitis. Any children had diabetes or other systemic conditions rather than ectodermal dysplasia was excluded from the study. The results showed that all children with Papillon - Lefevere syndrome had generalized type of aggressive periodontitis with grade three or four mobility and furcation involvement. While in group II. Children with ectodermal dysplasia only two of ten children had generalized type of aggressive periodontitis and six had sign of gingivitis with no obvious sign of aggressive periodontitis either localized or generalized and two had only bleeding oil with no signs for periodontitis. In group III [normal healthy children], no one of them showed pocket formation or any other sign of localized or generalized aggressive periodontitis and only mild to moderate gingivitis was noticed. From this study we concluded that there are strong relation between generalized aggressive periodontitis and Papillon - Lefevere syndrome and there is some relation between ectodermal dysplasia and generalized aggressive periodontitis. Aggressive periodontitis is a disease that needs a special care from the pediatric dentist to detect it as early as possible and differentiate it from other periodontal disease and know its relation to other systemic syndrome and genetic disorders
