The surgery of lower incisors should be performed carefully, assessing the possible presence of lingual canals, and avoiding the mistake of underpreparation by not adequately evaluating the clinical situation

Dens invaginatus is malformation of teeth probably resulting from an infolding of the dental papilla during tooth development. Affected teeth show a deep infolding of enamel and dentine starting from the foramen coecum or even the tip of the cusps, and which may extend deep into the root. Teeth most affected are maxillary lateral incisors and bilateral occurrence is not uncommon. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. Root canal therapy may present severe problems because of the complex anatomy of the teeth.  

The mandibular first premolar can be considered one of the most challenging teeth for the endodontist during endodontic procedures; because of the complexity of its root canal morphology and increased incidence of multiple canals. The knowledge of internal anatomy of root canals and their possible variations as well as use of magnification, operating microscope, radiographic examination and illumination, can increase the chances of finding additional canals and contribute to the success of endodontic treatment.

A case presentation of maxillary second molar with 3 mesio buccal (MB) canals.

The increased life expectancy has led to the increase in numbers of elderly patients seeking dental treatments, and more precisely root canal treatments. According to a survey of diplomates of […]

It is very important to identify obstacles and plan any strategies from the beginning to avoid problems that could cost us the success of the treatment   Preoperative radiograph identification, […]

Dental anomaly is a condition in which one or more teeth deviate from the normal in form, function, or position. And it includes abnormalities in teeth number, size, shape and […]

A thorough knowledge of the root canal anatomy and its variation is required for achieving success in root canal therapy, along with diagnosis, treatment planning and clinical expertise. Outcome of […]

Dens evaginatus (DE) is a relatively rare developmental anomaly that occurs more often in people of Asian descent than European descent. DE appears as a cusplike elevation of enamel, referred […]

One of the most common causes of failure in endodontics is missing canals.
The middle canal in lower molars is not an exception and has been studied by numerous authors in the literature.
Its prevalence ranges from 0,28% to 53,8% and it’s specially presents in the mesial root.
Using different X-ray angulations or with the help of CBCT we can confirm its existence.
Understanding the anatomy of the teeth is a key factor for the success of our treatment.
In this case we are treating a previously treated lower molar with some hidden anatomy.

A thorough knowledge of the root canal anatomy and its variations is required for achieving success in root canal therapy, along with diagnosis, treatment planning and clinical expertise,  One such […]

The presence of 3 rooted premolars called, little molars, is pretty infrequent. Found in only 1-4% of cases with regional variation. The two morphological types involve either two buccal and […]
