Traditional restorative dentistry propagated early operative intervention to remove diseased tissue and bacteria. Modern dentistry, however, emphasises on arresting the caries progression and restoring the tooth with minimum tissue destruction. Minimal invasive dentistry is based on this axiom.
A drawback in restorative dentistry is the occurrence of secondary caries[18,19] that has compelled us to practice a more extensive form in the past. MID also displays the same drawback. Our study, in accordance with other studies has also shown incomplete bacterial elimination with excavation only[20]. Several concepts using antimicrobial agents have been tried to eliminate bacteria underneath the restorations, the predominant one being the use of

Mechanism of action of TTO Tea tree oil is the volatile essential oil derived mainly from the Australian native plant, Melaleuca alternifolia. It is composed of terpene hydrocarbons, mainly monoterpenes, sesquiterpenes and their associated alcohols which are volatile, aromatic hydrocarbons[29]. Antibacterial activity of this essential oil has been discussed in the literature since 1940s[30-33] however, its appearance in the scientific literature started in the early 1990s[29].
Antimicrobial activity of tea tree oil is due to terpinen‑4‑ol, α‑terpineol and 1,8‑, which cause leakage of 260 nm‑light absorbing material and render cells susceptible to sodium chloride[34]. Thus, tea tree oil causes lysis and the loss of membrane integrity and function manifested by the leakage of ions and the inhibition of respiration.[29]
Mechanism of action of Aloe vera Aloe barbadensis Mill (A. vera), is a short succulent herb resembling a cactus, with green dagger shaped fleshy, spiny and marginated leaves, filled with a clear viscous gel which has potent antibacterial, antifungal, and antiviral properties[35,36]. The therapeutic use of aloe vera has been known to us since
