About

To evaluate the antimicrobial potency of Garlic Lemon extract irrigant versus physiological saline irrigant following partial pulpectomy in primary molars.

Full description

Pulpectomy is a suitable treatment of primary teeth with irreversible pulpitis, necrosis, or periodontitis due to caries or trauma. Due to the complex nature of the deciduous root canal system makes total removal of necrotic tissue by instrumentation alone impossible. Therefore, irrigation is a replenishing step to create a disinfectant atmosphere inside the root canal.

A variety of antiseptic and antibacterial irrigating solutions have been used such as (NaOCl), (CHX), and (EDTA). Due to their adverse effects, safety issues and cytotoxic reactions, Herbal products can be an alternative to these irrigants based on their previous history in medical field.

Herbal extracts such as garlic (Allium sativum) Shows a wide range of therapeutic effects due to the presence of allicin, ajoene & other thiosulfinates. It has antibacterial effect against wide range of gram-positive and gram-negative bacteria, anti-inflammatory, antioxidant, antiviral, antifungal, antitumor, immunomodulatory effects and tissue-dissolving capacity (Siddique, et al., 2020). According to (Elheeny., 2019) Allium sativum extract can be used efficiently as an irrigant for pulpectomy of primary molar root canals.

Lemon (Citrus Limon) as well has curative properties such as, antibacterial, antiviral, antifungal, anti-inflammatory, anti-cancerous activities and removal of the smear layer as well. Due to presence of ascorbic acid, phenolic acids, polyphenols, and dietary fibers.

the combination of Garlic-Lemon has been tested in adult teeth as an irrigant and showed an effective result equal to NaOCl (Siddique, et al., 2020).However, there is no studies have been performed to assess the combination of Garlic-lemon extract as an irrigant in deciduous molars.

Treatment:

Combination Product: Garlic-Lemon Extract irrigant

physiological saline irrigant

Active Comparator group

Description:

Normal saline solution exhibits no adverse effects on the developing successors; Serves primarily to facilitate root canal cleaning during the irrigation process, in comparison to other commercial synthetic irrigants such as Sodium hypochlorite (NaOCl), Chlorhexidine (CHX), Ethylenediamine tetra acetic acid (EDTA) which exhibit potential side effects and cytotoxic reactions (Sayadizadeh et al., 2019).

Treatment:

Other: physiological saline
