Background: Gingival biotype is a prognostic factor in different therapeutic and regenerative approaches in dentistry. Patients with thin biotype are more prone to recession, inflammation, compromised tissue response, therapeutic and regenerative procedures. Identification of gingival biotypes is therefore important for the treatment planning process in restorative and implant dentistry. The pu...

Implant placement and tooth restoration in the maxillary esthetic zone is challenging. In the case reported here, the treatment site was tooth # 8, which had been extracted one year previously. Available bone in three dimensions was evaluated by computerized tomography. The bucco-lingual bone width at the crest was 3 mm to 4 mm wide, an inadequate width for implant placement. Ridge expansion wa...

nowadays, due to recent developments and researches in dental science, it is possible to preserve and restore previously extracted cases such as teeth with extensive caries, fractured or less appropriate cases for crown coverage as well as teeth with external perforation caused by restorative pins. in order to restore the teeth with preservation of periodontium, we should know thoroughly physio...

AIMS Several studies have shown a large diversity in the prevalence, extent and severity of gingival recession as well as controversial conclusions of its associated factors. Therefore, the aim of this pilot study was to evaluate gingival recession with predisposing factors in young Vietnamese. METHODS A cross-sectional study using clinical examination was performed in 120 dental students. Or...

Tooth morphometry is known to be influenced by cultural, environmental and racial factors. Tooth size standards can be used in age and sex determination. One hundred models (50 males & 50 females) of normal occlusion were evaluated and significant correlations (p<0.001) were found to exist between the combined maxillary incisor widths and the maxillary intermolar and interpremolar arch widths. ...

The traditional method to calculate bending displacement of helical tooth is generally based on simplified tooth profile. Besides, the unbalance loading is not taken into account. To overcome this disadvantage, a new method to calculate bending deformation of helical tooth is introduced. First, gear section is divided into several copies along tooth width and each section’s moment of inertia is...

The purpose of this study was to produce an estimated equation for the prediction of unerupted cuspids and bicuspids for the Saudi population. In this study, dental casts of 65 Saudi subjects (37 males and 28 females) were used. The subjects' age ranged from 18 to 25 years. The mesiodistal width of all permanent teeth was measured. The data was subjected to regression analysis. Results showed t...

The aim of this study was to develop a method for estimating the chronological age of Indian adults based on the relationship between age and various morphological variables of canine teeth, obtained using orthopantomographs. Orthopantomographs of 120 selected patients were digitized, and radiographic images of the right maxillary canine in each case were processed using a computer aided drafti...

Wolf tooth is a common term used to describe the first premolar, a functionless remnant from modern horse’s ancestors. This study was performed to reveal possible relationships between morphometric characteristics of wolf tooth and its clinical importance in animal’s health. A total of 158 wolf teeth were extracted from 83 horses from 1.5 to 15 years of age during a period of one year and divid...

A novel nanometeric plasmonic filter in a tooth-shaped metal-insulator-metal waveguide is proposed and demonstrated numerically. An analytic model based on the scattering matrix method is given. The result reveals that the single tooth-shaped filter has a wavelength-filtering characteristic and an ultracompact size in the length of a few hundred nanometers, compared to gratinglike surface plasm...
