Eruption cysts: A series of 66 cases with clinical features.

BACKGROUND: An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. MATERIAL AND METHODS: 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. RESULTS: Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). CONCLUSIONS: Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision.

The effects of surface pretreatment on the microleakage of resin-modified glass-ionomer cement restorations.

OBJECTIVE: To evaluate the effect of different surface pretreatments on the marginal microleakage of Vitremer restorations. STUDY DESIGN: Class V cavities were prepared on the labial and lingual surfaces of extracted human third molar teeth. Cavities were randomly distributed into six groups according to surface treatment, as follows: Group NC (negative control): no surface treatment; Group VP (positive control): Vitremer Primer; Group PA: 32% phosphoric acid; Group PAA: 20% polyacrylic acid; Group PLP: self-etch adhesive (Prompt L Pop); Group PB: etch & rinse adhesive (Prime & Bond NT). All cavities were restored with Vitremer. Teeth were thermocycled, stained with 0.5% basic fuchsin dye and sectioned. Microleakage values were quantitatively assessed by linear measurement of dye penetration using image-analyzing software. Differences between occlusal and gingival microleakage values within groups were evaluated using paired t-tests, and differences among groups were analysed using one-way analysis of variance (ANOVA) and Tukey tests. RESULTS: There were statistically significant differences between the occlusal and gingival microleakage values for all groups (p < 0.05). Microleakage differed significantly among surface pretreatment groups (p < 0.001). The negative control and PLP groups showed similar microleakage values, but were significantly higher than other groups for both margins. Although there were no statistically significant differences between positive control and PA, PAA, PB groups, microleakage values of positive control group were smaller than all other experimental groups except for PB group. CONCLUSIONS: Vitremer restorations require surface pretreatment to prevent excessive microleakage. Pretreatment with etch & rinse adhesives and Vitremer Primer may reduce microleakage of Vitremer restorations.

Evaluation of microtensile bond strength of different fissure sealants to bovine enamel.

BACKGROUND: The aim of this study was to evaluate the microtensile bond strength (µTBS) of a new fissure sealant and compare it with conventional sealants which are applied to enamel alone, and also with self-etch and etch-and-rinse adhesives. METHODS: Enamel specimens were prepared and randomly distributed into three groups according to fissure sealant (Aegis, Helioseal F, Helioseal Clear). Each group was then subdivided according to adhesive system (Clearfil S3, Single Bond, no adhesive). A universal testing machine was used to measure µTBS, and data were analysed using one-way ANOVA and Tukey's tests. RESULTS: µTBS values for all Aegis subgroups were significantly lower than for comparable Helioseal F and Helioseal Clear subgroups (p < 0.05). No differences were observed in µTBS of Helioseal F and Helioseal Clear (p > 0.05). In the Helioseal Clear group, µTBS values for Single Bond were significantly higher than for Clearfil S3 (p < 0.05). However, no significant differences were found between the µTBS values of the adhesive subgroups in the Aegis or Helioseal F groups (p > 0.05). CONCLUSIONS: Sealant µTBS values may be affected by material content. The addition of an adhesive may improve µTBS values of sealant to enamel.

Evaluation of certain risk factors for early childhood caries in Samsun, Turkey.

AIM: Early childhood caries (ECC) is a relatively new term used to describe any stage of caries lesion in any primary tooth surface in a child under 6 years of age. The purpose of this study was to identify certain factors that influence the development of ECC among children in Samsun, Turkey. MATERIALS AND METHODS: Data were collected for 226 children (108 girls, 118 boys) aged 3-6 years. Questionnaires were administered to the mothers of participating children to obtain information on infant feeding habits and the mother's level of education and oral health knowledge. Clinical diagnoses of ECC were based on intraoral examinations conducted using a flashlight, disposable mirror and wooden tongue depressor. RESULTS: ECC was diagnosed in 46.9% of children. The mean dmf-t was 2.87. Significant associations were found between ECC prevalence and bottle feeding while sleeping and between ECC and the mother's level of education (p<0.05). The caries rate increased with the addition of sugar-containing substances to bottles; however, the increase was not statistically significant (p>0.05). There were no correlations observed between ECC and the mother's oral health knowledge or attitude (p>0.05). CONCLUSION: Within the limitation of this study, among the various factors investigated, infant feeding habits and the mother's level of education were found to have significant effects on the development of ECC.

Oral rehabilitation with endosseous implants in a child with ectodermal dysplasia: a case report.

AIM: The purpose of this article is to report the clinical course of a 12-year-old child with ectodermal dysplasia who was treated with an implant-supported overdenture for the mandible and an overdenture for the maxilla. CASE REPORT: Two dental implants were placed in the canine regions of the mandible. The maxillary teeth were prepared for the milled copings. Because the preparation of parallel walls was difficult, near-parallelism with an angle of convergence or taper of approximately 5 degrees was achieved. The cervical third of the teeth was prepared to be as parallel as possible to one another. In addition, the occlusal surfaces were reduced 1.5 mm, and the axial surfaces were reduced 1 mm. Occlusal reduction was performed to provide adequate thickness for the overlying denture base material. A chamfer finish line was prepared. The copings were cast with a Cr-Ni-based metal alloy and luted, bilateral balanced occlusion was developed using anatomic acrylic teeth. An impression was taken with an individual tray for impressions of overdentures. In response to the patient's dry mucosa, the impressions were taken using rapid-setting silicone impression material with high elasticity. Bilateral balanced occlusion was achieved using anatomic acrylic teeth for overdentures. The maxillary overdenture and implant-supported mandibular overdenture were prepared by conventional methods using thermal-curing acrylic resin. The patient was seen 48 hours later for adjustment, then after 1 and 2 weeks, 1, 3, and 6 months, and 1 year and he is still satisfied with his prosthesis both aesthetically and functionally. CONCLUSION: The use of endosseous implants in the prosthetic rehabilitation of children with ectodermal dysplasia may provide a considerable improvement in comparison with traditional prosthetic methods.
