Published: April 1995

Both gravimetry (measurement of weight loss of roots after root canal preparation) and planimetry (measurement of surface area corresponding to the removed dentin layer of canal walls on oro-vestibular and mesio-distal X-ray views of roots before and after the preparation) were used on the same samples for determination of the efficacy of root canal shaping instruments. There were no statistically significant differences between the results obtained using either the gravimetry or the planimetry indicating the evidence of reliability of results obtained using only the planimetry as a single method.

Odontogenic cutaneous fistulas are abnormal connections between the oral cavity and skin, often mistaken for skin infections. They typically result from dental infections but may also arise from salivary gland issues, tumors, or congenital anomalies. Accurate diagnosis is essential to prevent complications like infection, osteomyelitis, and discomfort.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.

Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.

Objectives: This study evaluates the effect of different irrigation solutions for postoperative pain in the regenerative endodontic treatments (RET) of necrotic teeth with open apex.

Materials And Methods: This study included necrotic, deeply carious lower molars of 42 patients. Access cavities of the teeth were opened and working lengths were measured at the first visit.

Purpose: This study investigated the synergistic effects of reduced graphene oxide (RGO) on the antibacterial activity of three calcium hydroxide-based intracanal medicaments with different vehicles.

Methods: Multispecies biofilms were cultured in a bovine root canal model. Intracanal medicaments containing nonaqueous vehicles, including N-methyl-2-pyrrolidone (NMP; CleaniCal), propylene glycol (PG; UltraCal XS), and polyethylene glycol (PEG; Calcipex II), were placed in the model.

Introduction: Traditional access cavity preparation involves removing the roof of the pulp chamber and smoothing the dentin bulges at the root canal orifice, thereby creating straight-line access. However, this may damage more healthy dental tissue and reduce the tooth's fracture resistance. This case series presents a novel minimally invasive endodontic protocol for one maxillary canine and four mandibular premolars, which required root canal therapy due to labial/buccal cervical decay that caused pulpitis or periapical periodontitis.
