low level lasers, cold or soft lasers: these lasers do not produce thermal effects on tissues and induce photoreactions in cellsthrough light stimulation which is called photobiostimulation. power of these lasers is usually under 250mw. the main point differentiating low level lasers and high power ones is the activation of photochemical reactions without heat formation. the most important fact...

Although sodium hypochlorite is the most frequently used canal irrigant during endodontic treatment, its complications are not as well recognized as its effectiveness. This report demonstrates that sodium hypochlorite extrusion during endodontic treatment can cause severe complications. A 5-year-old boy experienced immediate pain and swelling, ecchymosis in surrounding tissues, and profuse blee...

Dens invaginatus is a well-recognized phenomenon, and its endodontic treatment poses a challenge, especially for peri-invagination lesions with vital pulp. Here we describe the outcome of conservative treatment and follow-up in a case of type III dens invaginatus. Cone-beam computed tomography was used for diagnosis and follow-up. Pulp vitality was preserved with endodontic treatment of only an...

The pulp and periodontium are intimately related owing to the various communications present between the two. So a disease in one can progress to the other posing difficulties in the management of such lesions. Proper diagnosis is essential in endodontic-periodontal lesions so that proper treatment can be prescribed. Treatment of combined endo-perio lesions is complex and proper sequence of man...

Endodontic–periodontal lesions present challenges to the clinician as far as diagnosis and prognosis of the involved teeth are concerned. Etiologic factors such as bacteria, fungi, and viruses as well as various contributing factors such as trauma, root resorptions, perforations, and dental malformations play an important role in the development and progression of such lesions. Treatment and pr...

The endodontic treatment of maxillary molar with an aberrant root canal morphology can be diagnostically and technically challenging.1 Unusual root canal morphology in multirooted teeth is a constant challenge for diagnosis and successful endodontic treatment. Presence of extra canals, lateral canals, deltas is commonly encountered.2 This case report is presented to illustrate and describe the ...

The dental literature contains a small number of reports of primary multirooted anomalies and even fewer reports on the clinical significance of these findings. Specifically, there are fewer reports of primary radicular anomalies than of permanent radicular anomalies. Knowledge of the size, morphology and variation of the roots and root canals of a primary tooth is useful in performing endodont...

The main goal of endodontic treatment is healing of the periapical tissues which are gained by elimination of bacteria and their byproducts from the canal and prevention from reinfection. Understanding of root canal anatomy is an essential part in endodontic treatment. Anatomic forms and variations in special teeth should be well known, one of them is extra roots/ canals. Although possible aber...

This article reports non-surgical endodontic retreatment of two patients with persistent or recurrent periapical lesions, who had previously undergone surgical and non-surgical endodontic therapy respectively. It further discusses and reviews the relevance of classification of periapical lesions, the explanation behind healing of periapical lesions by endodontic therapy alone, causes of persist...
