Carious lesion; Glass ionomer cement; Primary teeth; Retention rate


Regardless of the numerous causes, children fear the dentist for a variety of reasons, including parental unpreparedness, community influences, previous medical or dental experiences, previous dental settings, injections, dental materials, drill sounds, dental staff, and socioeconomic concerns. Conventionally, the carious tissue is removed using a local anesthetic, rubber dams, and rotational handpieces and it is preferred by the majority of dentists. Traditionally, the dental procedures are unpleasant for youngsters, therefore they avoid them. To evaluate the retention of zinc-reinforced glass ionomer cement (ZRGIC) in primary molars by sealing the carious tissue (SoCT) using the finger pressure technique in uncooperative children. Only healthy, uncooperative children with occlusal carious lesions on primary molars were involved in the study. The study did not include any children who had symptoms from a primary molar carious lesion. The ZRGIC was used by finger pressure technique to seal the occlusal carious lesion in the primary molars. The children were called back for assessments semiannually (6 months) and annually (12 months). Success and failure rates were compared based on molar tooth type and arch type. The SPSS (21.0) was used for the analysis, and the significance level was set at a 5% level of probability with a 95% confidence interval. A total of 108 children aged 5.3±0.6 years with 265 primary molars and no signs or symptoms were available for evaluation in the study. After 6-month and 1-year follow-ups, the ZRGIC-created finger pressure approach for sealing carious tissues showed a high retention rate of 98.5% and 95.5%, respectively. Among primary first molars, the ZRGIC failure rate was 2.1%, but it was only 1.2% among primary second molars, and retention was 97% among the latter rather than 92.7% among the former. There was a statistically significant difference between the retention rates for semiannual (p=0.001) and annual visits (p=0.005). At six months, the retention rate for maxillary molars was significantly (p = 0.001) higher than that for the mandibular arch. Similarly, a statistically significant difference (p=0.035) was found in the percentage of ZRGIC failures in mandibular and maxillary molars after 12 months. The sealing the carious tissue by ZRGIC using the finger pressure method has shown statistically significant success rates at the semiannual (98.5%) and annual (95.5%) follow-up visits. The sealing carious lesions with ZRGIC by using the finger pressure technique can be used in uncooperative children with occlusal carious lesions.
