OBJECTIVE To observe dynamic changes in root resorption repair, tooth movement relapse and alveolar bone microstructure following the application of orthodontic force. MATERIALS AND METHODS Forces of 20 g, 50 g or 100 g were delivered to the left maxillary first molars of fifteen 10-week-old rats for 14 days. Each rat was subjected to micro-computed tomography scanning at 0, 3, 7, 10, 14, 28 ...

this report describes a case of an eight years old girl who was treated for complicated crown fracture of right maxillary central incisor because of a sport accident. for the tooth total pulpotomy was performed in order to achieve apexogenesis and the tooth was restored with a composite resin. the patient was reviewed over 10 years. at first the tooth showed continued root development and compl...

A root canal treatment generally involves the removal and replacement of a tooth’s pulp. The pulp is soft tissue containing blood vessels, nerves and connective tissue. dThe pulp is found in a canal that runs through the center of the hard tissue on the inside of the tooth (the dentin). dThe pulp extends from the pulp chamber in the crown down through the root canal to the tip of the root in th...

Here, we report the management of a type I endoperiodontal lesion with furcation bone loss. A 59-year-old female attended our hospital with the chief complaint of mobility of tooth 46 and recurrent gingival swelling around the tooth. She previously received dental treatment from two dentists, but her condition did not improve. The tooth manifested the symptoms of typical periodontitis, such as ...

When a tooth is avulsed and replanted following traumatic dental injury, complications such as replacement and inflammatory resorption may occur. Ultimately, resorption may result in loss of the tooth. This case report describes a traumatic injury to a permanent tooth resulting in complete root resorption within a short period, which required surgery. In the present case, improper treatment mea...

Traumatic injury to a primary tooth can affect the underlying permanent tooth germ, and may result in a malformed, hypoplastic crown or root. The degree and nature of malformation depends on the injury. Most trauma cases can be diagnosed using conventional 2-dimensional radiographs, but some cases may benefit from more advanced 3-dimensional imaging such as cone-beam computed tomography (CBCT)....

Instead of extraction this case report presents an alternative treatment option for a maxillary incisor with a vertical root fracture (VRF) causing pain in a 78-year-old patient. After retreatment of the existing root canal filling the tooth was stabilized with a dentine adhesive and a composite restoration. Then the tooth was extracted, the VRF gap enlarged with a small diamond bur and the exi...

Autogenous transplantation is an economical as well as the most sorted option for the treatment of badly destroyed teeth when a suitable donor tooth is available. This paper presents successful auto transplantation of a mature mandibular right third molar (48) without anatomical variance is used to replace a grossly decayed mandibular right first molar (46). The mandibular first molar was nonre...

Dilaceration of the permanent tooth usually is a consequence of traumatic injuries to the primary teeth. Although it may appear anywhere in the long axis of the tooth, i.e., crown, cementoenamel junction, or root, most often the root is involved. However, crown dilaceration is a rare condition representing 3% of the total injuries. Maxillary incisors are more susceptible to such injury and affe...

We described a combined periodontal-endodontic lesion, which was caused by a palatogingival groove and an additional root. An interdisciplinary approach involving endodontic therapy, mineral trioxide aggregate (MTA) filling, root resection, guided tissue regeneration, and papillary reconstruction was used for the case. The tooth presents morphologically and functionally normal except tooth disc...
