Tetracycline-stained teeth in Jerusalem preschool children.

The prevalence of tetracycline-stained teeth was studied in 965 5-year-olds attending compulsory kindergarten in West Jerusalem in 1971. In addition, demographic data were collected to determine the socioeconomic status of the children's families. The prevalence of children with stained teeth was 8.0%, males being affected twice as often as females. The prevalence of staining was significantly higher in children of lower socioeconomic status.

Crown size asymmetry in males with fra (X) or Martin-Bell syndrome.

We measured the mesio-distal and bucco-lingual crown diameters of 13 males with the fra(X) or Martin-Bell syndrome. Fluctuating crown-size asymmetry was calculated and compared with values obtained in normal Caucasian children and also with a sample of 19 males with Down syndrome. A statistically significant increased asymmetry was found in the fra(X) males when compared to normal control individuals. In the maxilla, Down syndrome males showed a significantly higher tooth crown asymmetry than fra(X) males. (less than 0.02); in the mandible, no significant differences were found between the 2 groups. It is suggested that crown size asymmetry be included in the evaluation of fra(X) males.

Hypodontia: a polygenic trait--a family study among Israeli Jews.

A high prevalence of hypodontia was detected among 820 first degree relatives of 305 probands and there was an increased risk if a second family member was affected. Hypodontia is a common trait in the population, and a deviation from normal sex ratio was observed in those affected. These results suggest a polygenic mode of inheritance.

Composite resin support of undermined enamel in amalgam restorations.

PURPOSE: Previous reports suggested that cusp fracture strength increases with the use of bonded composites. The purpose of this study was to assess fracture resistance of undermined cusps, when supported by a layer of bonded composite, in extensive occlusal carious lesions. METHODS: Primary and permanent molars in children that were treated included those with extensive occlusal caries with undermined enamel in one or more cavity walls. Following local anesthesia and rubber dam application, cavity outline was prepared with a #330 tungsten bur, and the carious lesion removed. If an unsupported cusp was present, the inner enamel wall and the dentine floor adjacent to this wall was etched with a gel containing 37% phosphoric acid, rinsed and dried and Scotch bond multipurpose applied; a 1-mm layer of Z100 was applied to the unsupported cusp and polymerized; a nongamma 2 amalgam or Z100 was used to restore the tooth. RESULTS: The children were re-examined after 6, 12 or 24 months. A total of 42 restorations were placed in 39 children (26 boys and 13 girls), ranging in age from 4 to 16 years (mean age 9 years, 6 months). This is a preliminary report on 30 restorations, followed up from 6 to 24 months. All 30 restorations were successful in preventing cuspal fracture. Four teeth developed caries in the proximal surface, but were unrelated to the restoration. CONCLUSIONS: It was concluded that bonded composite can prevent fracture of unsupported cusps.

Clinical performance of esthetic posterior crowns in primary molars: a pilot study.

PURPOSE: The aim of this pilot study was to assess the clinical performance of esthetic crowns and to compare these to conventional stainless steel crowns (SSC). METHODS: Twenty two crowns (11 conventional and 11 esthetic) were placed in mandibular primary molars obeying the following criteria: the tooth was not mobile; no fistulae were present; the tooth had at least one caries free or properly restored antagonist and had to be in contact with one adjacent tooth mesially, in the case of the primary second molars or distally in the case of the primary first molars. Crown preparation was done in a conventional manner, but reduction was more extensive for the thicker esthetic crowns, to allow for proper occlusion. The crowns were evaluated clinically and radiographically after 6 months and the following parameters were assessed: gingival health, marginal extension, crown adequacy, proper position or occlusion, proximal contact, chipping of the facing (for esthetic crowns) and cement removal. RESULTS: At the 6 month evaluation all esthetic crowns were intact, without chipping of the facing, and no excess of cement was observed in both groups. No difference was found for marginal extension, occlusion, proximal contact, crown adequacy, and bone resorption, but a significant difference was found for periodontal health between esthetic crowns and conventional SSC (P < 0.001 McNemar test). CONCLUSIONS: The esthetic crowns assessed had several inconveniences, as they resulted in poor gingival health, are very expensive, and, although not measured, are bulky and without a natural appearance.

A comparison of restorations for children with early childhood caries treated under general anesthesia or conscious sedation.

PURPOSE: There is no data in the dental literature concerning the quality of the restorations performed in young children with early childhood caries (ECC) under sedation as compared with those treated under general anesthesia (GA). The aim of this study was to compare the quality of restorations and recurrent caries in 65 children with ECC who had dental treatment under GA or sedation. METHODS: Thirty-four children, mean age 34.4 months were treated under GA and 31 children with a mean age of 37.2 months were treated under sedation and re-examined 6-24 months after completion of treatment. The quality of the restorations was evaluated using a modified Cvar & Ryge index. RESULTS: Fifty-nine percent of children treated under GA required further dental treatment compared to 74% of children treated under sedation. The majority of the required treatment was due to new caries: 57% in the GA group and 60% in the sedation group. A total of 248 restorations were evaluated for the GA group, with a 94% success rate for marginal adaptation, 92% success for anatomic form, and 97% had no secondary caries. In the sedation group, out of 224 restorations, 78% demonstrated perfect marginal adaptation, 79% showed adequate anatomic form, and 90% had no secondary caries. Successful marginal adaptation was found in 90% of strip crowns placed under GA, compared to 63% of those placed under sedation. CONCLUSION: It is concluded that the outcome of treatments related to quality of the restorations performed under GA is better for all parameters examined.

Dental health behavior of children with BBTD treated using general anesthesia or sedation, and of their parents in a recall examination.

The aim of the study was to assess the dental status and dental health behavior of children with Baby Bottle tooth Decay treated using general anesthesia or sedation, and the dental health behavior of their parents in a recall examination. The study population consisted of sixty-five children, among whom thirty-four were treated using general anesthesia and thirty-one using sedation. The recall examination included a full dental examination from which the children's dif index could be drawn. Loe's plaque index was used to assess the amount of plaque on the teeth. Sociodemographic information and the dental health behavior of the parents and children were obtained. Plaque index was similar in the general anesthesia and sedation groups. The parents of the general anesthesia group were younger than the parents of the sedation group (35.0 +/- 6.7 and 38.8 +/- 6.2 for the fathers, and 32.4 +/- 5.9 and 34.9 +/- 5.3 for the mother, respectively). More firstborn children were treated using general anesthesia than using sedation. Significantly more siblings were treated in the sedation group. Children treated using sedation had significantly more siblings treated in the same mode. Parents of the children in the general anesthesia group were significantly more involved in brushing their children's teeth than the other group. In the sedation group, more children brush their teeth without parental help. Significantly more children in the general anesthesia group reduced their sweet consumption than in the sedation group. We conclude that preventive behaviors were more frequently adopted among the families of children treated using general anesthesia.

Mineral trioxide aggregate vs. formocresol in pulpotomized primary molars: a preliminary report.

PURPOSE: The aim of this study was to compare the effect of mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomized primary molars with carious pulp exposure. METHODS: Forty-five primary molars of 26 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) or FC (control) group by a toss of a coin. Following removal of the coronal pulp and hemostasis the pulp stumps were covered with an MTA paste in the experimental group. In the control group, FC was placed with a cotton pellet over the pulp stumps for 5 minutes and removed; the pulp stumps were then covered by zinc oxide-eugenol (ZOE) paste. The teeth of both groups were restored with stainless steel crowns. Eighteen children with 32 teeth arrived for clinical and radiographic follow-up evaluation ranging from 6 to 30 months. RESULTS: The follow-up evaluations revealed only one failure (internal resorption detected at a 17 months postoperative evaluation) in a molar treated with formocresol. None of the MTA-treated teeth showed any clinical or radiographic pathology. Pulp canal obliteration was observed in 9 of 32 (28%) evaluated molars. This finding was detected in 2 out of the 15 teeth treated with FC (13%) and in 7 out of the 17 treated with MTA (41%). CONCLUSION: MTA showed clinical and radiographic success as a dressing material following pulpotomy in primary teeth and seems to be a suitable replacement for formocresol in primary teeth.

Marginal leakage of impregnated Class 2 composites in primary molars: an in vivo study.

In vivo impregnation of the cervical margin was used in an attempt to prevent leakage of class 2 composite restorations in primary molars. Examination after 18 months demonstrated clinical success of the restorations. However, the exfoliated teeth presented extensive dye penetration at the approximal margins of the restorations, suggesting that impregnation did not prevent marginal leakage.

Histopathology of the pulp in primary incisors with deep dentinal caries.

The purpose of this study was to assess the histological appearance of the pulp of human primary incisors extracted because of deep, unrestorable caries, and to determine how clinical pulp exposures affected the histological status of the pulp compared to nonexposures. Caries was removed carefully from all teeth after fixation; 24 incisors had pulp exposures, and 29 teeth had no pulp exposures. Histological examination showed normal pulps in 69% of the teeth without pulp exposures, compared to 33% of teeth with exposed pulps (P < 0.05). Microabscesses were observed in 33% of cases with pulp exposures, compared to 10% of cases without pulp exposures. In this study, 46 of 53 pulps remained vital in spite of the multiple and deep carious lesions. Teeth without pulp exposures were diagnosed in the treatable category in 20 of 26 cases.
