Finite element analysis for fracture resistance of reattached human tooth fragment with different types of retentive preparation techniques.

Objective: Restoration of traumatized incisors by reattachment of the original tooth fragment appears to be the most conservative treatment approach. But the measurement of forces acting on natural tooth in-vivo poses many challenges. The advent of finite element analysis (FEA) has made it possible to demonstrate the propagation of stress through each part of a tooth and its restoration.

Decreased sleep in children and their behavioral problems in dental operatory.

Purpose: This study was conducted to examine the contribution of inadequate sleep and its associated factors, on behavior and cooperation of children in the dental operatory.

Materials And Methods: A cross-sectional study was conducted on 100 healthy children at the time of their initial visit to the dental hospital, ranging from preschoolers to adolescents. Data acquisition was done by a questionnaire.

Frenectomy with semilunar coronally repositioned flap: A single stage approach - simple solution for complex problem.

Gingival recession is defined as the displacement of gingival margin apical to cementoenamel junction. Aberrant frenum attachment can contribute to the progression of recession by generating tension on the marginal tissues. Treating such defects is a two stage procedure-frenectomy and recession coverage procedure.

From hopeless to good prognosis: journey of a failing tooth.

Chronic periodontitis, along with associated clinical findings such as pathologic tooth migration, diastema, functional and aesthetic aberrations, poses an immense challenge to a dental professional. These findings convert clinical decision making into a daunting task and adversely affect the prognosis and the treatment plan for the presenting clinical problem. An interdisciplinary approach aimed at restoring functional and aesthetic needs of the affected individual within the limitations of such a compromised clinical scenario may be a viable alternative to any radical treatment causing loss of natural tooth structure such as extraction.

Effect of remineralizing agents on surface microhardness of primary and permanent teeth after erosion.

Purpose: The purposes of this study were to compare the susceptibility of human primary and permanent enamel to dental erosion caused by soft drinks and to compare in vitro the remineralization potential of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste, 1.23 percent acidulated phosphate fluoride (APF) gel, and iron supplement.

Methods: Fifteen extracted primary and permanent teeth were used for sample preparation.

Atomic force microscopic comparison of remineralization with casein-phosphopeptide amorphous calcium phosphate paste, acidulated phosphate fluoride gel and iron supplement in primary and permanent teeth: An in-vitro study.

Context: Demineralization of tooth by erosion is caused by frequent contact between the tooth surface and acids present in soft drinks.

Aim: The present study objective was to evaluate the remineralization potential of casein-phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste, 1.23% acidulated phosphate fluoride (APF) gel and iron supplement on dental erosion by soft drinks in human primary and permanent enamel using atomic force microscopy (AFM).

Autogenous tooth fragment reattachment: a multidisciplinary management for complicated crown-root fracture with biologic width violation.

Fractures of multiple permanent anterior teeth can be a traumatic experience for children, with functional, esthetic and psychological aspects. The treatment of complicated crown-root fractures (CRFs) is more challenging when the biologic width is violated. This paper presents a case of 12-year boy with complicated CRF of teeth #12 and #21, and horizontal crown fracture of tooth #11.

Accidental periapical extrusion of non-setting calcium hydroxide: unusual bone response and management.

Premixed non-setting calcium hydroxide is frequently used as interim root canal dressing in endodontically involved permanent teeth and as obturating paste in deciduous teeth in pediatric dentistry. Wide apex in both cases makes it more prone for deliberate extrusion especially when applied with pressure delivery systems. Contrary to common belief the mix was not resorbed in two years with the complaint of insufficiency in mastication.

Clinical management of a complicated crown-root fracture using autogenous tooth fragment: A biological restorative approach.

Trauma resulting in crown-root fracture is one of the most challenging fracture types. However, biologic width involvement should be carefully evaluated. Reattachment of tooth fragment to a fractured tooth remains as the treatment of choice because of its simplicity, natural esthetics, and conservation of tooth structure.

Multidisciplinary management of an unusual case of multiple developmental defects in lateral incisor followed by intrusive injury to primary incisors.

Dental traumatic injuries occur frequently in children. The close relationship between the apices of primary teeth and germ of the permanent successors can lead to developmental disturbances in the permanent dentition. Developmental disorder can occur in any tooth.

Biological restoration in a young patient with a complicated crown root fracture with an autogenous tooth fragment.

Crown-root fractures are one of the most challenging trauma cases to treat. Reattachment of tooth fragment to a fractured tooth being a simple procedure conserves the tooth structure, maintains the natural esthetics value and is thus considered as a favorable treatment option. The reattachment procedure using composite resin should be considered if the subgingival fracture can be exposed to provide isolation after a careful evaluation of the biologic width involvement.

Odontomas--silent tormentors of teeth eruption, shedding and occlusion.

Odontomas are the most common odontogenic tumours of the jaws, characterised by their slow growth and non-aggressive behaviour. They usually remain asymptomatic, and are diagnosed on routine radiographs. Clinically, they are often associated with delayed eruption or impaction of permanent teeth and retained primary teeth.

Endodontic treatment and esthetic management of a primary double tooth with direct composite using silicone buildup guide.

Gemination and fusion are morphological dental anomalies, characterized by the formation of a clinically wide tooth. Gemination occurs when one tooth bud tries to divide, while fusion occurs if two buds unite. The terms double teeth, double formation, conjoined teeth, geminifusion, vicinifusion and dental twinning are often used to describe fusion and gemination.

Facial talon cusp: A rarity, report of a case with one year follow up and flashback on reported cases.

Talon cusp is a relatively uncommon developmental anomaly characterized by cusp-like projections, usually presenting on palatal/lingual surface of the anterior teeth. This cusp resembles an eagle's talon, and hence the name. Normal enamel and dentin covers the cusp, which may or may not contain an extension of pulp.

Dens invaginatus in primary maxillary molar: a rare case report and review of literature.

Dens invaginatus is a rare developmental anomaly. It is unusual to find this anomaly in primary dentition. Diagnosis of this dens invaginatus is important due to possible pulpal involvement.

Compound odontoma associated with an unerupted rotated and dilacerated maxillary central incisor.

Odontomas are benign tumors containing various component tissues of teeth. They usually remain asymptomatic and are diagnosed on routine radiographs. Clinically, they are often associated with delayed eruption or impaction of permanent teeth and retained primary teeth.

Multidisciplinary management of multiple maxillary anterior supernumerary teeth: a case report.

Supernumerary teeth are a relatively frequent disorder of odontogenesis. They may occur alone or in multiple; be unilateral or bilateral; and appear in the maxilla, mandible, or both. Mesiodens is a supernumerary tooth in the anterior maxilla between the two central incisors.
