Oral findings and periodontal status in children, adolescents and young adults suffering from renal failure.

AIM: Describe the oral condition of chronic renal failure and healthy subjects, and the relationship between oral variables, chronic renal failure (CRF) conditions, and their treatment. MATERIALS AND METHODS: Four renal failure groups: chronic renal disease (n=22); undergoing dialysis (n=22); after dialysis and transplant (n=21); and after transplant (n=32), and a healthy control (n=38) were examined. Caries, enamel hypoplasia, pulp obliteration, plaque index, gingival bleeding, recession, overgrowth and index, probing depths, attachment loss, renal treatments and their relations with the oral variables were analysed. RESULTS: The renal failure groups had higher gingival index (GI) and bleeding, probing depths, attachment loss, hypoplasia and obliteration and less caries, than the control. Plaque was higher in the dialysis and pre-dialysis (PD) groups. Overgrowth was evident after transplant. The PD group showed lower GI than other renal groups. Dialysis duration and end-stage renal failure significantly correlated with gingivitis, probing depth, attachment loss and enamel hypoplasia. Immuran correlated positively with probing depth, gingival recession and attachment loss. Normiten and Nifedipine had positive correlations with gingival overgrowth. CONCLUSIONS: CRF patients are characterized by pulp obliteration, gingival and periodontal diseases. Duration of end stage renal failure and type of systemic treatment have a significant influence on the oral condition.

Children with baby bottle tooth decay treated under general anesthesia or sedation: behavior in a follow-up visit.

The purpose of the present study was to compare the behaviors of a group of children, who were treated for baby bottle tooth decay (BBTD) under general anesthesia (GA) or under sedation in a dental school environment in a routine follow-up examination, and to assess the dental anxiety levels of the parents. Sixty-five children, who were treated for BBTD in the Pediatric Dentistry clinic of the Hebrew University-Hadassah School of Dental Medicine between 1995-1997 under GA (34 children) or sedation (31 children). The parents of these children agreed to attend our clinic for recall examination 13 months post treatment following a telephone conversation. Frankl's behavioral scale and the sitting pattern were recorded for each child. In the sedation group, Frankl's scores of the present visits were then compared to the scores recorded at the initial examination visit that were obtained from the dental records. The accompanying parents were asked to note the number of visits to the dentist in the past two years, and to complete Corah's dental anxiety scale (DAS). No difference was observed between the children in both groups. Most of the children in the GA and in the sedation groups sat alone on the dental chair, without the assistance of the parents. Parents of the sedation group showed higher scores than the GA group in the total DAS (9.35 and 8.90 respectively), however these differences were not statistically significant. It is concluded that children treated for BBTD under GA or under sedation at a very young age behave similarly in a follow-up examination nearly 13 months postoperatively.

The preventive resin (composite resin/sealant) restoration: nine-year results.

This study was performed to examine the 9-year success of the composite resin/sealant restoration, which uses "sealing for prevention" of fissure caries rather than "cavity extension for prevention." Three hundred thirty-two Class I restorations were placed in the occlusal surfaces of 240 permanent molar teeth in 114 children aged 6 to 14. Cavity preparations were made in occlusal surfaces, and caries was removed with no attempt to create any additional retention or remove undermined enamel. Exposed dentin was covered with Dycal and the cavity was restored with Radiopaque Adaptic, which was then covered with Delton fissure sealant. Incipient lesions confined to the enamel were restored only with Delton. After 9 years, 79 restorations in 28 subjects were examined for sealant retention, marginal staining, and the presence of dental caries. Forty-three restorations (54%) had completely retained sealants, 20 (25%) had sustained partial loss, and 16 (20%) of the restorations had lost all sealant. Dental caries occurred in 19 (25%) of the restorations that had sealant loss. An additional 16 teeth had proximal caries unrelated to the occlusal restoration. These findings demonstrated that the composite resin/sealant (preventive resin) restoration produced excellent long-term results.

Evaluation of students' performance in obtaining local anaesthesia in children.

This study was designed to determine the success of various local anaesthesia techniques as assessed by the presence or absence of pain during restorative procedures performed by senior undergraduate dental students in a pedodontic clinic. Data gathered from the treatment of 151 patients by 43 students recorded the frequency of pain complaints during procedures for which local anaesthesia had been employed. It was found that 73% of the administrations were successful. The proportion of children who complained of pain during the operative procedure was significantly higher in those with a previous history of a painful dental experience.

Pulp therapy in the primary dentition.

Several treatment options for pulp therapy in primary teeth are reviewed. Conservative treatments are recommended for primary teeth whose pulps have the potential to recover once the irritation has been removed. The role of dentin permeability and microleakage is emphasized when protective basis and indirect pulp treatment are discussed. Alternative dressings for formocresol pulpotomies such as 6.25% glutaraldehyde solution, antigen-extracted allogeneic dentin matrix, and crude bone morphogenetic protein are reported with promising results. Pulpectomy is recommended for teeth with evidence of chronic inflammation involving radicular pulp or pulp necrosis with and without periapical involvement. The main disadvantage of zinc oxide-eugenol paste, widely used for primary root fillings in the United States, is its slow resorption rate, frequently much slower than that of the root. Other root canal pastes containing iodoform, or a modification of this with the addition of calcium hydroxide, are being utilized in South America, Japan, and Europe.

Assessment of marginal leakage around Class II composite restorations in retrieved primary molars.

The aim of the present investigation was to evaluate, by means of dye penetration, the microleakage around Class II composite restorations, in retrieved primary molars that functioned in the mouth for at least one year. The experimental material consisted of 13 exfoliated primary molars that had been restored with Herculite (Kerr Corporation, Romulus, Michigan 48174 USA) at least one year previously, utilizing an incremental or a bulk filling technique. The retrieved teeth were insulated with utility wax and nail polish, immersed in 2% basic fuchsin, embedded in acrylic resin, and ground off to various depths. The marginal leakage was assessed according the degree of dye penetration at the occlusal and cervical margins. No difference was observed between the two filling techniques. In most teeth, no leakage at the occlusal margins was observed; minimal leakage, limited to the enamel, was observed at the occlusal margins of two teeth, one of each filling technique. Severe penetration was evident at the cervical margin of three restorations, two of them filled incrementally and the third using the bulk technique. Mild to moderate penetration was observed at the cervical margin in the majority of the other restorations. It was concluded that an incremental filling technique could not eliminate microleakage at the cervical margins of Class II composite restorations.

A clinical, radiographic, and SEM evaluation of Class 2 composite restorations in primary teeth.

Sixty class 2 composite resin restorations were placed in 22 children and evaluated at baseline, six months, and one year. Radiographs were used for evaluation, in addition to clinical examinations, photographs, and scanning electron micrographs of epoxy resin casts of retrieved teeth. It was concluded that radiographs are necessary to detect a large percentage of failures at the gingival margins of class 2 composites.

Clinical, radiographic, SEM evaluation and assessment of microleakage of Class II composite restorations.

The influence of incremental or bulk filling techniques, and reapplication of unfilled resin (impregnation) to the margins with an enamel bonding agent, on marginal adaptation was evaluated in Class II composite restorations by clinical, radiographic, scanning electron microscope (SEM) and dye penetration techniques. Cavities were prepared in 80 extracted permanent posterior teeth. All cavity walls were treated with polyacrylic acid for 10 seconds. The enamel was etched for 1 minute, rinsed, dried, and lined with Scotchbond. Forty cavities were filled by increments of P30 and 40 cavities in bulk. The margins of the restorations of 20 teeth in each group were re-etched for 30 seconds and Concise Enamel Bond reapplied. The clinical scores were excellent for all restorations. Radiographic examination showed twice as many bubbles in the incrementally filled restoration than in the group filled in bulk. In 53 teeth, a radiolucent area between the dentin and the restorative material was found. After sectioning, this area was found to correspond to a hard material. The SEM revealed excellent margins in the groups of teeth that were impregnated with an unfilled resin, whereas 13 teeth without impregnation showed defective margins. The dye penetration, as a test for marginal leakage, was minimal at the occlusal surface of all teeth. At the cervical surface, 10.5% of the impregnated teeth showed severe dye penetration compared to 18% of the nonimpregnated teeth. No correlation was found between dye penetration at the cervical surface and the thickness of the residual enamel in this area.(ABSTRACT TRUNCATED AT 250 WORDS)

Morphological changes in the attached and keratinized gingiva and gingival sulcus in the mixed dentition period. A 5-year longitudinal study.

A longitudinal study was undertaken to examine the changes in the sulcus probing depth, keratinized and attached gingiva during the mixed dentition period. 54 children aged 7 to 9 years at the first examination were examined twice, with an interval of 5 years. Sulcus probing depth and keratinized gingiva were examined at the buccal aspect of the incisors, and either right or left cuspids and posterior areas. The width of the attached gingiva was obtained by subtracting the probing depth from the width of the keratinized gingiva. When compared to primary predecessors, the permanent teeth had a deeper probing depth, narrower attached gingiva and at the maxillary teeth, a wider keratinized gingiva. When a permanent tooth was present at both examinations, there was a significant increase in width of the attached gingiva with a corresponding decrease in probing depth, and a slight beginning of an increase in the width of keratinized gingiva. Previous and the present findings indicate that during the early years after eruption of the permanent tooth, an increase in width of the attached gingiva takes place, without occlusal migration of the marginal gingiva whereas, at later stages, this coronal migration takes place, concomitant to tooth eruption.
