Öğe Association of maternal-child characteristics as a factor in early childhood caries and salivary bacterial counts(2006) Ersin N.K.; Eronat N.; Cogulu D.; Uzel A.; Aksit S.The aim of this study was to investigate the caries-related microorganisms in saliva and the prevalence of Early childhood caries (ECC) in 15- to 35-month-old Turkish children and their associations with the characteristics of the mothers, socioeconomic criteria, and feeding habits of the children. Methods: Saliva samples of 101 children were studied to determine the numbers of Streptococcus mutans, lactobacilli, and Candida albicans. A questionnaire regarding the characteristics of the mothers, socioeconomic criteria, and feeding habits of the children was carried out before the dental examinations of the mother-child pairs. Results: The regression analyses revealed DMFS scores of the mothers as an impact factor for the children's caries experience. The prolonged usage of feeding bottle with sweetened milk, pacifier use, and maternal sharing were strongly associated with the colonization of S mutans, lactobacilli, and C albicans, respectively. A significant correlation was also found between maternal education and S mutans. Conclusion: Data indicated that the mother's DMFS scores, education, and feeding habits were strong risk indicators for the colonization of caries-related micro-organisms and ECC.Öğe A clinical evaluation of resin-based composite and glass ionomer cement restorations placed in primary teeth using the ART approach: Results at 24 months(American Dental Association, 2006) Ersin N.K.; Candan U.; Aykut A.; Önçag Ö.; Eronat C.; Kose T.Background. The authors evaluated the 24-month performance of a packable resin-based composite/dentin bonding system and a high-viscosity glass ionomer cement (GIC) in restorations placed in primary molars with the atraumatic restorative treatment (ART) approach. Methods. Three dentists placed 419 restorations in 219 children aged 6 through 10 years who had bilateral matched pairs of carious posterior Class I and II primary teeth. They used a split-mouth design to place the two materials, which were assigned randomly to contralateral sides. The authors evaluated the restorations according to U.S. Public Health Service Ryge criteria. Results. After 24 months, 96.7 percent of the Class I GIC restorations and 91 percent of the resin-based composite restorations survived, while the success rates for the Class II restorations were 76.1 percent and 82 percent for the GIC and resin-based composite restorations, respectively. The survival rate of the Class II resin-based composite restorations was 5.9 percent higher than that of the GIC restorations at the 24-month evaluation, but this difference was not statistically significant. However, the study results showed a statistically significant difference in survival rates between Class I and II restorations for both materials. Conclusion and Clinical Implications. The two-year clinical performance of both materials was satisfactory for the restoration of Class I and II primary molars using the ART approach.Öğe Effectiveness of 2-year application of schoolbased chlorhexidine varnish, sodium fluoride gel, and dental health education programs in high-risk adolescents(2008) Ersin N.K.; Eden E.; Eronat N.; Totu F.I.; Ates M.Objective: To compare the caries preventive effects of 2-year application of school-based chlorhexidine varnish, sodium fluoride gel, and dental health education programs among a high-risk group of 11- to 13-year-olds with low caries activity. Method and Materials: A total of 149 subjects who had previous caries experience in the primary dentition and Streptococcus mutans levels higher than 105 at baseline with 0 DMFS index were selected for this randomized clinical trial. Subjects were allocated to one of 3 groups for treatment with chlorhexidine varnish (n = 50), sodium fluoride gel (n = 50), or a dental health education program (n = 49), which were repeated throughout the 2-year study. The outcomes examined at the end of the study were the caries increment (DMFS index), dental plaque scores, and salivary S mutans counts. Results: The subjects in the education group showed a significant increase in the salivary levels of S mutans in comparison with the other groups (P = .004), but there was no significant difference among the groups in the caries increment after 2 years, with mean DMFS ± SD as 0.95 ± 1.33, 0.88 ± 1.47, and 1.05 ± 2.01 in the chlorhexidine varnish, sodium fluoride gel, and education groups, respectively. There were also no significant differences in the pre- and posttreatment plaque scores between the groups. Conclusion: Although all 3 preventive programs in this high-caries-risk group of children with low caries activity resulted in similar plaque and caries values after 2 years, longer follow-up studies are needed to clarify the effect of reduction in S mutans growth by chemotherapeutic agents in caries inciden. © 2008 by Quintessence Publishing Co Inc.Öğe Lenz microphthalmia syndrome with dental anomalies: A case report(2003) Ersin N.K.; Tugsel Z.; Gökce B.; Ozpinar B.; Eronat N.This report describes the dental management and 7-year follow-up of a 14-year-old boy who showed the typical characteristics of Lenz microphthalmia syndrome, a rare genetic disorder characterized by multiple abnormalities. The main features of the syndrome are microphthalmia, developmental retardation, ear abnormalities, microcephaly, skeletal, digital and urogenital anomalies. The dental anomalies include micrognathia, hypodontia, agenesis of permanent teeth, conic-shaped incisors, and taurodontic molars. The purpose of the report was to document specific oral manifestations and dental anomalies and their management associated with a previously reported case.Öğe A long-term effect of caries-related factors in initially caries-free children(2008) Cogulu D.; Ersin N.K.; Uzel A.; Eronat N.; Aksit S.Aim. The aim of this study was to examine the rate and pattern of early childhood caries development in caries-free children based on their dental plaque accumulations, salivary Streptococcus mutans levels, maternal sharing, oral hygiene, and feeding attitudes at baseline and at 24-month follow-up period. Design. A total of 92 children, aged between 15 to 35 months, comprised the study group. The children's dental examinations were first carried out at baseline, and 56 of them were re-examined 24 months later to determine the changes in dental status. The mothers were also interviewed at each examination based on a prepared questionnaire. Results. The prevalence of caries incidence was 45% at 24-month evaluation period among initially caries-free children. The new caries formation was mostly observed on occlusal and aproximal surfaces of maxillary molars (28% and 26%) followed by mesial, distal and buccal surfaces of anterior teeth, respectively. Significant correlations between dental caries formation and maternal sharing, S. mutans levels, and plaque scores were found. Conclusion. The results indicated that early S. mutans colonization, high plaque accumulation, and maternal sharing were important factors on a child's caries development. © 2007 The Authors.Öğe Mesiodens in primary, mixed and permanent dentitions: A clinical and radiographic study(2004) Ersin N.K.; Candan U.; Alpoz A.R.; Akay C.The term mesiodens refers to a supernumerary tooth located between the maxillary central incisors. The aim of the study was to investigate the characteristics of mesiodens among children in Turkey. The study population involved 24 children who attended the Department of Pediatric Dentistry, Ege University for dental problems. The characteristics of mesiodens were obtained from clinical and radiographic examinations. Results showed that twenty-four patients had thirty-four mesiodens for an average of 1.42 mesiodens per person. Males were affected approximately 3 times more frequently in comparison with females. Forty-two percent of the patients had bilateral mesiodens. All of the mesiodens were conical in shape and 91 % were in the downward position. The age and sex distribution, location, direction, eruption of mesiodens and effects on permanent maxillary incisors were also presented in this study. It could be concluded that, delayed, ectopic or asymmetric eruption of the central incisors should alert the clinician to the possibility of a mesiodens.Öğe No adverse effect to bonding following caries disinfection with chlorhexidine(2009) Ersin N.K.; Candan U.; Aykut A.; Eronat C.; Belli S.Purpose: The purpose of this study was to evaluate the effect of 2% chlorhexidine-based cavity disinfectant on the microtensile bond strength of 3 restorative materials to caries-affected and sound primary dentin. Methods: Eighteen exfoliated primary molars with occlusal caries and 18 sound primary molars were randomly divided into 3 experimental groups, according to the following restorative materials: (1) high-viscosity glass-ionomer cement (GIC; KetacMolar); (2) resin-modified GIC (Vitremer); and (3) dentin adhesive (Prime&Bond NT) with a packable composite (Surefil). The molars were further divided into 2 subgroups according to the application of chlorhexidine-based cavity disinfectant (Consepsis). Standard restoration blocks of 5 mm high were built up over the treated surfaces. Bond strength results were evaluated using by 1-way analysis of variance, and multiple comparisons were done via Tukey's test (P<.05). Results: No statistically significant differences were found between the high-viscosity and resin-modified GIC and composite showed the highest bond strength values on both dentin surfaces. The distribution of failure modes between the high-viscosity and resin-modified GICs were mostly cohesive where adhesive failures were noted significantly in the composite. Conclusion: Using 2% chlorhexidine gluconate did not interfere with the microtensile bond strength of glass ionomer cements and composite.Öğe Transmission of Streptococcus mutans in a group of Turkish families(2004) Ersin N.K.; Kocabas E.H.; Alpoz A.R.; Uzel A.Background/aims: To investigate the transmission of Streptococcus mutans in a group of Turkish families using AP-polymerase chain reaction (PCR) detection. Methods: Eight mothers who had high S. mutans levels in unstimulated saliva and 8 children aged between 2 and 3 years participated in the study. Plaque samples from each child were collected with the tips of sterile toothpicks for S. mutans counts. Although not part of the original study design, S. mutans samples were also obtained from the unstimulated saliva of the three fathers who shared the same households. Three typical isolates of S. mutans were isolated from TYCSB agar of each subject and identified by sugar fermentation tests. S. mutans ATCC 10449 was used as the reference strain. AP-PCR was conducted with OPA-05 primer. Results: All of the mothers and fathers shared the similar genotypes within their children. The fathers also harbored similar genotypes to their spouses. Conclusion: The mothers or the fathers could be the source for the transmission of S. mutans to their children.
