in order to achieve a long-lasting effect, one of the main goals in root canal treatment is to eliminate the endodontic bacteria. conventional chemomechanical debridement is considered as the basic treatment in root canal therapy, but adjunctive techniques such as antimicrobial photodynamic therapy (apdt) can also be helpful. the aim of this study was to evaluate reports in the scientific liter...

The aim of this in vitro study was to evaluate the influence of endodontic therapy, veneer preparation, and their association on fracture resistance and deflection of pulpless anterior teeth and assess whether restoration with quartz fiber-reinforced post can influence these properties. Seventy-five freshly extracted human maxillary central incisors were selected. Teeth were randomly divided in...

abstract: cone-beam computed tomography (cbct) has been accepted as a useful tool for diagnosis and treatment in endodontics. despite a growing trend toward using cbct in endodontic practice the cbct images should be interpreted carefully. this case report presents a case that showed radiolucency inside and around a tooth which was free of pathologic changes under a dental operative microscope ...

abstract : inflammatory external root resorption (ierr) is a pathological phenomenon of microbial origin. this stu dy reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (rct). radiographic investigation revealed periapical radiolucencies...

the developmental abnormality of tooth resulting from the infolding of enamel/dentin into the root is called dens invaginatus. management of such cases is usually challenging due to the morphological complexity of root canal system. this report presents a rare treatment protocol of a clinical case of oehler’s type iii dens invaginatus combined with an endodontic lesion in a vital maxillary late...

alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. while the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. even today, with best modalities of tooth preservation, there is a group of elderly individuals who do not benefit from modern preventiv...

tricho-dento-osseous syndrome is a rare autosomal dominant disorder. immunosuppressive drugs, though critical to the treatment, have undesirable effects on patient's healing process. this is a case report of a 10-year-old female, suffering from tricho-dento-osseous syndrome who was under treatment with penicillamine. as the dental treatment was sought too late, both central and lateral incisors...

introduction: this study compared the root canal microbial count of necrotic teeth after irrigation with 6% sodium hypochlorite (naocl) (single session treatment) and two-session root canal treatment with two-week application of calcium hydroxide (ch) mixed with 0.2% chlorhexidine (chx) as intracanal medicament. methods and materials: in this randomized clinical trial, single-rooted necrotic te...
