OBJECTIVE This study evaluates the effect of calcium hydroxide dressing on microleakage of composite restorations following non-vital bleaching. METHODS A total of 45 sound extracted human maxillary central incisors underwent endodontic treatment. The teeth were randomly divided into three groups (n=15). In group 1, access cavities were restored with composite. In group 2, the teeth underwent...

Regional odontodysplasia is a rare dental anomaly affecting both primary and adult dentitions in the maxilla or mandible or both jaws, whilst involvement of the maxilla is more common [1-2]. In most cases, one quadrant is affected. One of the characteristics of this anomaly is discolored and soft teeth that can be accompanied by swelling or abscess. In this anomaly, enamel and dentin are thin a...

Mandibular second premolars with three canals (Type V, Vertucci) and separate foramina are very rare. The anatomy of the pulp chamber floor in these premolars usually reveals one lingual and two buccal orifices at the same level. This case report describes a second premolar with three canals and an unusual pulpal floor anatomy with one distobuccal and one distolingual orifice at the same level ...

This study evaluated the influence of bleaching protocols on intrapulpal temperature and fracture strength of the bleached teeth. Ninety maxillary incisors were assigned to 9 groups (n=10): G1: 35% carbamide peroxide (35% CP), G2: 38% hydrogen peroxide (38% HP), G3: halogen light, G4: LED-laser, G5: 35% CP + halogen light, G6: 38% HP + halogen light, G7: 35% CP + LED-laser, G8: 38% HP + LED-las...

iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. the present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (cem) cement. the perforation was chemically cleaned and then physical...

Objectives: The principle of measurement using the TCI (Tooth Coronal Index) method is to compare pulp chamber height with a person's chronological age based on formation secondary dentin. purpose this study estimate in lower canines periapical radiographs measurement.
 Materials and Methods: This an observational analytic 42 samples parallel technique canines. Samples were measured for CH...
