This study aims to evaluate and compare the clinical and radiographic outcomes of Lesion sterilization and tissue repair using zinc oxide/ 6-gingerol mix versus triple antibiotic paste in non-vital primary molars.
Age from 4 to 8 years.
Both sexes
Children must have at least two restorable non-vital primary molars
Periapical radiolucency.
Presence of systemic diseases.
Teeth with physiological mobility near exfoliation time.
Teeth with vital pulp.
Parallel
Zinc oxide/ 6-gingerol mix
Other interventionLesion sterilization and tissue repair (LSTR) using zinc oxide/ 6-gingerol mix.
Triple antibiotic paste
Other interventionLesion sterilization and tissue repair (LSTR) using triple antibiotic paste.
Assessment of pain
Pain will be assessed using age-appropriate pain scales (5-point Likert scale for children) with 0 typically representing "no pain" and 4 representing "very high/extreme pain".
Tooth mobility
Tooth mobility is the horizontal or vertical looseness of a tooth beyond its normal physiological range. It is graded from 0 (no mobility) to 3 (severe, \>2mm or vertical movement).
