objective: loss of tooth structure due to dental caries and cavity preparation can reduce fracture resistance, especially in endodontically treated teeth. the aim of the present study was to evaluate fracture resistance of pulpotomized primary molar teeth restored with extensive multisurface amalgam restorations. materials and methods: eighty extracted carious human primary molar teeth were sel...

background: the aim of the present study was to estimate chronological age based on third molar development and to determine the association between dental age and third molar calcifi cation stages. materials and methods: in this cross-sectional study, 505 digital panoramic radiographs of 223 males (44.2%) and 282 females (55.8%) between the age of 6 and 17 were selected from patients who were ...

The influence of calcium to phosphate (Ca/P) molar ratio on the extent of mineralization in a model (poly)acrylamide gel was investigated under simulated physiological conditions. We hypothesized that the optimal growth of hydroxyapatite crystals will take place at the stoichiometric Ca/P molar ratio of 1.67. Phosphate ions were incorporated during the polymerization of the gel and mineralizati...

This is an analysis of the incidence of molar pregnancies and those of complete and partial molar pregnancies across the reproductive age range for BP Koirala Institute of Health Sciences (BPKIHS) in the period 2010-2011. Patients with molar pregnancies registered with BPKIHS from January 2008 to January 2010 were identified. The overall number of molar pregnancies registered was compared to th...

AIM The aim of this study was to determine the frequency and distribution of third-molar agenesis in orthodontic patients from the East Anatolian Region of Turkey. METHODS AND MATERIALS Our data were obtained from the panoramic radiographs of the 2,579 patients 12 to 16 years of age in the Department of Orthodontics at the Atatürk University in Erzurum, Turkey. Subjects with congenital deform...

BACKGROUND Although third-molar extraction is common in the U.S., there are few reports on the relationship between third-molar extraction and temporomandibular disorder (TMD). The aim of this study was to investigate this potential association. METHODS The authors enrolled study subjects on their 15th birthdays and followed them continuously for a minimum of five years. The authors ascertain...

An overview of the effects of phase separation of aqueous mixtures of gelatin and dextran on the fractionation in molar mass of these two components is given. Molar mass distributions in coexisting phases were investigated using size exclusion chromatography with multiangle laser light scattering. The initial molar mass of the native material, concentration, and temperature were varied. The res...

Impacted mandibular third molar tooth has the potential to induce periodontal problems in the distal root of second molar tooth. Platelet-rich plasma (PRP) is an autologous biomaterial which has been used to enhance soft and hard tissue regeneration. The aim of the present study was to evaluate the effectiveness of PRP in management of periodontal pocket at the distal root of mandibular second ...

OBJECTIVES Localization of the mandibular canal (MC) and measurement of the height and width of the available alveolar bone at the proposed implant site in the posterior segment of the mandible using cone-beam computed tomography (CBCT) in patients with a single missing tooth. MATERIALS AND METHODS A cross-sectional study was performed where CBCT scans of the patients with a single missing to...
