At the sixth month, failure rate for composite restoration was 4.28% (three restorations) compared to biological restoration which was 8.19% (five restorations). One patient reported with gross fracture of all the four restorations (two composite restorations and two biological) due to trauma. The other two patients had lost a total of three biological restorations and the composite restorations were intact. However, the result was statistically nonsignificant. The greater loss of biological restorations may mainly be accounted for by lack of precision fit and operator's clinical preparation.
Recurrent carious lesions around the margins of the restorations were observed at 9 months and 12 months, but the difference between composite and biological group was not statistically significant. A total of 11.43% composite restorations and 9.68% biological restorations had evidence of recurrent caries over the 12-month follow-up period. These seven recurrent carious lesions were seen in three children and they presented with recurrent caries in both composite and biological restorations. Children presenting with ECC are a high caries risk group and failure to follow proper preventive regimen can result in caries recurrence. Lack of compliance with the preventive instructions resulting in caries recurrence even in treated cases of ECC has also been reported
previously by Sheehy et al , [12] Berkowitz et al , [13] Eidelman et al , [14] and Almeida et al. [15] The percentage of patients reporting with recurrent caries in this study is much lower than in the above said studies, which can be attributed to the preventive measures instituted along with parental counseling regarding diet and oral hygiene.
All the endodontically treated primary teeth near the age of primary tooth exfoliation with intraradicular retainers and biological posts were examined with pre and postoperative IOPA X-ray in order to check for normal root
resorption as suggested by Wanderlay. [16] At recall visits, all the roots with intraradicular retainers and biological posts showed normal root resorption patterns [Figure 16].
The evaluation of both parents/patients response to the questionnaire regarding their perception to treatment indicated positive response vis a vis improvements in esthetics, self-esteem, and speech were particularly positive. Lower cost for biological restorations was cited as positive feature by patients/parents. The duration of the entire treatment period was mentioned as a negative feature by three patients. When asked if they would go through the same treatment again, two patients in group I and one in group II said "no" and referred to the treatment duration as stressful experience during treatment, since four of the patients had to undergo treatment under conscious sedation.
