Maxillary tuberosity fractures during molar teeth extraction can occur commonly in dental practice; however, very few cases are reported and discussed in the literature. This article presents a case of large fracture of maxillary tuberosity during extraction of first maxillary molar tooth and its conservative treatment outcomes.

AIM To describe vascular anatomy of the maxillary sinus in dentate specimens dissected from human cadavers. METHODS Twenty dentate maxillary specimens were dissected, anatomically prepared, and injected with liquid latex for a better visualization of the maxillary sinus artery. RESULTS We found an intraosseous anastomosis in 100% and an extraosseous anastomosis in 90% of the cases. The ante...

We show that the results of photoemission and inverse photoemission experiments on bulk copper can be quantitatively described within band-structure theory, with no evidence of effects beyond the single-quasiparticle approximation. The well-known discrepancies between the experimental band structure and the Kohn-Sham eigenvalues of density functional theory are almost completely corrected by se...

BACKGROUND The aim of this study is to compare the dento-skeletal effects of rapid maxillary expansion (RME) and mixed maxillary expansion (MME), assessed on posteroanterior (PA) cephalograms. METHODS Treatment groups consisted of 42 patients; mean age in RME group (n = 21,13 female and 8 male subjects) was 8.8 years ± 1.37 at T0 and 9.6 years ± 1.45 at T1 and mean age in MME group (n = 21, 1...

OBJECTIVE To examine the effect of bite force on the displacement and stress distribution of orthodontic mini-implants (OMIs) in the molar region according to placement site, insertion angle, and loading direction. METHODS Five finite element models were created using micro-computed tomography (microCT) images of the maxilla and mandible. OMIs were placed at one maxillary and two mandibular p...

AIM Presenting a rare complication of an odontogenic infection extending to the orbit. BACKGROUND A 45-year-old male patient reported with periorbital swelling of eyelids, of the left eye, foul smelling nasal discharge and a pus draining sinus on the left lower eyelid area. CASE DESCRIPTION The patient gave history of pain in the left upper first molar tooth 1 week back. His intraoral exami...

BACKGROUND The aim of this study was to determine the effect of the maxillary posterior dentoalveolar discrepancy (MPDD) on the angulation of maxillary molars in open bite subjects. METHODS Pre-treatment lateral cephalograms of 90 young adults with skeletal open bite were examined. The sample initially included six groups categorized according to MPDD condition (present or absent) and sagitta...
