    Retention were scored using a modified United States Public Health Service (USPHS) criterion.

    follow up will be 3,6,9,12 month

  • marginal adaptation of bio-flex crown,zirconia, and endo-crown

    marginal adaptation were scored using a modified United States Public Health Service (USPHS) criterion.

    follow up will be 3,6,9,12 month

  • fracture of restoration of bio-flex crown,zirconia, and endo-crown

    fracture of restoration were scored using a modified United States Public Health Service (USPHS) criterion.

    follow up will be 3,6,9,12 month

  • gingival health of bio-flex crown,zirconia, and endo-crown

    • Dental plaque accumulation and gingival condition were assessed using plaque index (PI) and GI.

    follow up will be 3,6,9,12 month

Secondary Outcomes (1)

  • parent's satisfaction analysis

    follow up will be 3,6,9,12 month

Other Outcomes (1)

  • Microbiological analysis

    follow up will be 3,6,9,12 month

Study Arms (3)

bio-flex crown

ACTIVE COMPARATOR

bio-flex crown will be used as a final restoration for pulp treated primary molar, selection of suitable sized crown , it will be cement with glass ionomer cement after pulpotmy procdure clincal performance, parent satsification ,bacterial adherence will be evaluated with a follow up period 1 year

Procedure: treatment option for primary second molar

endo-crown

ACTIVE COMPARATOR

endo-crown will be used as a final restoration for pulp treated primary molar, after pulpotomy procdure endo-crown preperation design will be done and CAD/CAM, endo crown will be luted according to e-max protocol clincal performance, parent satsification ,bacterial adherence will be evaluated with a follow up period 1 year

Procedure: treatment option for primary second molar

zirconia crown

OTHER

zirconia crown will be used as a final restoration for pulp treated primary molar, selection of suitable sized crown after preperation of tooth and use try-in kit to select siutable size ,zirconia is sensitive for blood contamination , it will be cement with glass ionomer cement after pulpotmy procdure clincal performance, parent satsification ,bacterial adherence will be evaluated with a follow up period 1 year

Procedure: treatment option for primary second molar
