THE primary purpose of the masticatory process is to apply forces to the nutritional substances which are taken into the mouth, thereby causing a reduction in their size. The mechanism for this action includes the medium of tooth structure which not only applies these forces directly to the food masses, but is itself subject to the effects of these forces. In general, the effects of forces appl...

F ollowing extraction of a natal or neonatal tooth, continued growth of the dental papilla may occur and a tooth-like form may develop.'^ This report describes an atypical tooth form (probably the result of continued growth of the retained dental papilla) that abscessed and may have caused delayed eruption of the adjacent primary lateral incisor. A 13-month-old white male presented to the autho...

this paper reports multidisciplinary treatment of a dental trauma case to achieve a favorable prognosis. a healthy 14-year-old girl reported avulsion of teeth 11 and 21 which had occurred three months earlier. the initial treatment consisting of replantation with a semi-rigid splint was performed in hospital. at presentation, the patient was still using the semi-rigid splint. the clinical exami...

The unique morphology of dilacerated and S-shaped root canals often poses utmost challenges in their endodontic management. Dilaceration is defined as developmental anomaly which there has been an abrupt change the axial inclination between crown a tooth. Periapical radiographs CBCT are most appropriate way to diagnose presence dilacerations. Also, clinician required have insight tooth related ...

In the past few years bioimpedance has been used in many applications in dentistry, such as estimating the length of root canals and the physical properties of enamel. Despite the significant number of studies using bioimpedance to investigate the dental structure, many of them use only the real component of bioimpedance, i.e., the resistance, disregarding the information provided by the imagin...

our aiin has been to correlate animal experiments and investigations on man, the former serving as a basis for the latter, It is obvious that these two means, taken in conjunction, hold out the best hope for the discovery of the aetiology of dental disease and for the evolution of suitable methods for its elimination. It has been shownl 2 that normal, well-developed teeth are more resistant to ...

objective: the aim of the present study was to evaluate the structure and distribution of glycoconjugates during molar tooth germ development in mice materials and methods: sixteen tooth germs were obtained from balb/c mice embryos 15 to 18 days post-gestation and fixed in 10% formalin. after routine tissue processing, 5 μm sections were cut and stained with bsa1-b4 and pna using the lectin his...

fusion is a developmental anomaly defined as the :union: of two normally separated tooth buds or the partial splitting of one tooth bud into two buds. depending on the stage of development, fusion may be either complete or incomplete. the significance of this particular case was that this fusion occurred in a posterior permanent mandibular tooth, while such a manifestation is more reported in m...

Tooth enamel is the hardest substance in the human body and has a unique combination of hardness and fracture toughness that protects teeth from dental caries, the most common chronic disease worldwide. In addition to a high mineral content, tooth enamel comprises organic material that is important for mechanical performance and influences the initiation and progression of caries; however, the ...

Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by the invagination of the crown surface during odontogenesis that enters the pulp chamber of the affected tooth. Depending on the complexity of invagination, the tooth might present with pulp necrosis, open apex and a complicated root canal system. This case report presents an Oehlers' type 2 dens-invaginatus...
