Background:

This study aimed to compare the effect of glide path preparation (manual versus mechanical) on postoperative pain following single-visit root canal treatment using two NiTi file systems (TruNatomy vs. Reciproc Blue).

Materials And Methods:

A total of 140 asymptomatic, necrotic teeth indicated for primary root canal treatment were assigned to four equal groups (n = 35): Group IA: TruNatomy with TruNatomy Glider, Group IB: TruNatomy with manual #10/#15 K-files, Group IIA: Reciproc Blue with R-Pilot, and Group IIB: Reciproc Blue with manual #10/#15 K-files. Pain intensity was measured using a Visual Analog Scale (VAS) at 6, 12, 24, and 48 h after treatment. Patients also recorded the number of 400 mg ibuprofen tablets taken for pain relief.

Results:

At the 12-h mark, rotary instrumentation (Group I) resulted in significantly higher VAS scores compared to reciprocating instrumentation (Group II) (P = 0.033), specifically in Subgroup A (with engine-driven glide path; P = 0.033). No significant differences in pain were observed in the subgroups without a glide path. Analgesic consumption was similar across all the groups (P > 0.05).

Conclusion:

Postoperative pain was comparable between rotary and reciprocating systems over a 48-h period. Reciprocating instrumentation showed slightly lower pain at 12 h. The glide path technique had no significant influence, offering flexibility in clinical practice.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
