Most mandibular second molars are usually found to have two roots (76%) or one root (22%). The incidence of 3 roots anatomy in such teeth is considered a rare finding […]
3 rooted Lower Second Molar
Most mandibular second molars are usually found to have two roots (76%) or one root (22%). The incidence of 3 roots anatomy in such teeth is considered a rare finding […]
Retreatment of teeth with a complex root system anatomy #1
The second maxillary premolar may have 1 to 3 roots: with one root canal in 75-96% of cases, with two root canals in 4-24% and three root canals in 0-1%. […]
Middle mesial canal – a case series
Middle mesial canal (MMC) is an additional canal found in mandibular first molars. The knowledge of its presence and its detection, negotiation, disinfection and sealing plays paramount importance in the […]
The endodontic ledge: causes and management
As endodontists we often encounter retreatment cases with procedural errors such as canal blockages, ledges, instrument fractures and perforations. The ledge is defined as an iatrogenic deviation from the original […]
Four-Rooted Maxillary Molars
The maxillary first molar typically exhibits complex root canal anatomy, commonly presenting with three roots—two buccal and one palatal. However, anatomical variations, such as the presence of a fourth root, […]
Selective Root Canal Re-Treatement of Lower Left Pre-Molar
In retreatment cases , the clinician has to deal with many mishaps such as underfilled, missed and obstructed canals as also with iatrogenic damages as separated instruments and perforations. Underfilled […]
Management of anatomy in a first tricky premolar (Deep Split)
The clinician must be aware of the possible anatomical variations of these teeth and their relationship to adjacent anatomical structures when planning and performing endodontic procedures.
Retreatment case with two types of perforations
Root perforations were the second greatest cause of failure accounting for 9.62% of all unsuccessful cases. Seltzer et al. also attributed 3.52% of all endodontic failures to perforation. This perforation […]
Retreatment of teeth with a complex root system anatomy #1
Modern endodontic treatment is based on optimal cleaning,disinfection and high-quiality obturation of the root canal system.Anatomy is considered as a key factor in the healing process.That is why a clinician have to be aware of all normal,possible and abnormal variations in the teeth anatomy for achieving a maximum clinical success.In the article presents clinical example that demonstrate the complexity of endodontic retreatment of the maxillary left premolar
Dental Trauma: Forever classic, Never boring
A 23 years old, female patient, was referred to my practice for an endodontic treatment on tooth 11. Patient complained of pain above the root and was concerned of the […]
A story of a dilacerated premolar
Premolars are the most versatile teeth in regards of anatomy. One of the most challenging anatomical variations we have to face is dilaceration. Abrupt curvatures complicate the RCT especially when […]
Mysterious pathology, fascinating anatomy & healing- a case of NSRCT of tooth 44
A periapical pathology, could be a result of caries, trauma, periodontally compromised oral cavity or even a thermal and chemical insult to the tooth. Effective cleaning, shaping and disinfection is the key to a successful endodontic treatment. A deep understanding of the anatomy of a root canal system, is of high value while performing a non-surgical root canal treatment. We often come across mandibular premolars with aberrant root canal anatomies. They often present with multiple canals, splits and accessory canals.
This article describes a case of NSRCT of a mandibular premolar with 1-2 configuration and it presented with a big peri-apical radiolucency.
