Occlusal restoration using fissure sealant instead of "extension for prevention".

This study was conducted to determine the success of a conservative cavity preparation using the principle of "sealing for prevention" rather than cavity "extension for prevention". Three hundred and twenty one restorations were placed in 234 teeth of 110 subjects, ages six to fourteen, with a mean age of eight years. After three years, 273 restorations were examined. Caries appeared in ten teeth and sealant wear occurred in sixteen restorations. Complete sealant loss was observed in two restorations and partial loss in thirty-nine, leaving 224 restorations with complete retention of the sealant. These preliminary results demonstrate that conservative cavity preparation with sealing for prevention is a successful technique which conserves valuable tooth structure.

Assessment of two doses of intranasal midazolam for sedation of young pediatric dental patients.

The purpose of this study was to assess the effectiveness of two doses of intranasal midazolam on sedation of young children for dental treatment. Thirty uncooperative children, mean age of 32 months, who needed at least two restorative visits, participated in this study. The patients were assigned randomly to receive either 0.2 mg/kg or 0.3 mg/kg of midazolam intranasally, with the alternate regimen administered at the second appointment. All the children received 50% nitrous oxide, and were restrained in a Papoose Board (Olympic Medical Group, Seattle, WA) with a head holder. Degree of alertness, crying, and movement were evaluated at baseline and at 5-min intervals throughout the procedure. Evaluation of overall behavior at each session was performed by one investigator, blind to the dose, using a separate rating scale. The reliability of ratings was assessed by two investigators from videotapes of the procedures. Statistical analysis showed no differences (P > 0.05) in the behavior of the children receiving the two doses. Successful sedation, as assessed by lack of or minimal crying and/or movement that interrupted treatment, was observed in all the treatment visits with both doses (mean score 4.66 +/- 1.09 for 0.3 mg and 4.40 +/- 1.04 for 0.2 mg). No adverse effects were observed, and all the treatments were completed successfully.

Conservative multidisciplinary treatment approach in an unusual odontodysplasia.

An unusual case of odontodysplasia is presented, involving both primary and permanent dentition, with oligodontia of permanent teeth and hypoplasia, taurodontism and incomplete eruption of a first permanent molar. In order to improve the patient's appearance, occlusion and function, his intra- and inter-arch relationships were altered. To accomplish this, a multidisciplinary treatment approach was adopted, involving restorative and prosthetic treatments by a pediatric dentist, accompanied by periodontal surgery, endodontics and orthodontics.

Intranasal midazolam better at effecting amnesia after sedation than oral hydroxyzine: a pilot study.

Providing amnesia about a surgery is a desired side effect of a medication. This study compares anterograde amnesic effects of midazolam with hydroxyzine in children undergoing dental treatment with those drugs plus nitrous oxide, using a recall test. Thirty ASAI children 24-28 months, were shown a Standard-Binet intelligence scale-memory for objects subtest before entering treatment room. Twenty-lone randomly determined children received 3.7 mg/kg hydroxyzine 45 min before treatment or 0.2 mg/kg intranasal midazolam in two succeeding appointments, alternatively. Recall in the 30-subject treatment group was 90%. Recall in the 21-subject treatment group was 71% for hydroxyzine and 29% for midazolam. Midazolam was more effective in creating amnesia than hydroxyzine in this study.

The effectiveness of midazolam and hydroxyzine as sedative agents for young pediatric dental patients.

The purpose of the study was to compare hydroxyzine (HYD) and 0.2mg/Kg midazolam (MDZ) as sedative agents for young pediatric dental patients. Twenty-nine healthy two-to-four-year-old children participated in the study. Hydroxyzine was dripped nasally 10 minutes before treatment. The patient's crying, alertness, movement and general behavior were blindly assessed and statistically analyzed. No differences were found between the mean general behavior scores nor between the first and second visits in both groups. A significant difference (p < 0.02) was found in the acceptance of the face and nasal masks by children of the midazolam group between the first and second appointments. None of the children of this group cried nor moved at the first visit. The results of the study indicate that midazolam is somewhat more effective than hydroxyzine as a sedative agent for short procedures in young pediatric dental patients.
