There is a growing interest in the relationship between occlusion and posture because of a greater incidence of neck and trunk pain in patients with occlusal dysfunction. The study was designed to verify whether an alteration of the spinal column alignment may be experimentally induced in rats as a consequence of altering dental occlusion and also to investigate whether the spinal column underw...

The study investigates the gender predictability of permanent maxillary first molar teeth. Mesio distal width of 30 permanent maxillary first molar teeth from casts of 15 male and 15 female patients between the age group of 1725 were measured. Results showed that permanent maxillary first molar tooth exhibited sexual dimorphism but accuracy of gender predictability was only moderate.

PURPOSE This study investigated maxillary third molars and their relation to the maxillary sinus using panoramic radiography and cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 395 maxillary third molars in 234 patients were examined using panoramic radiographs and CBCT images. We examined the eruption level of the maxillary third molars, the available retromolar space,...

Introdouction: Cone-beam computed tomography (CBCT) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. The aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the CBCT technique. Materials and methods: In this retrospective study, a total of 105 c...

The Ectopic Eruption of the Maxillary Permanent First Molar (EEMPFM) is an eruption anomaly, characterized for maxillary permanent first molar’s impaction in distal surface deciduous second molar. etiology related with change axial axis molar associated missing space maxilla. diagnosis combination clinical and complementary examination. There are two types Eruption: reversible irreversible. irr...

The purpose of this study was to determine the effects of the Jones jig appliance on distal movement of maxillary molars and reciprocal effects on premolars and maxillary incisors. Cephalometric radiographs before and after orthodontic treatment of 72 consecutively treated patients, 46 females and 26 males, were measured to define treatment changes attributed to the Jones jig. Comparative measu...

background and aims. due to anatomic variation in tooth anatomy between populations, this study compared the buccolingual (bl) and mesiodistal (md) dimensions of primary molars with those of stainless steel crowns (sscs) in an iranian population. materials and methods. impressions were taken from both dental arches of children, and casts were poured. teeth with caries, restoration, hypoplasia o...

introduction: ectopic tooth eruption may result owing to one of 3 processes: developmentaldisturbance, iatrogenic activity, or pathologic process, such as a tumor or a cyst. in rare cases, occlusion of the sinus ostia may predispose a patient to develop a maxillary sinus mucocele. when the maxillary sinus is invaded, symptoms usually occur late in the process.   case report: a 17 years old boy ...

Iatrogenic tooth displacement is a rare complication during extraction of impacted molars, but displacement of a maxillary third molar into the maxillary sinus, infratemporal fossa, buccal space, pterygomandibular space, and lateral pharyngeal space has been reported. Currently, 6 published reports describe third molar displacement into the lateral pharyngeal space, only 1 of which involved the...

Abstract  Hypercementosis is identified by an excessive, non-neoplastic deposition of radicular cementum and is mostly presented as a solitary lesion or in rare cases as a multiple type. It usually occurs in the premolar and molar region of mandible with no sex predilection. In this paper, we reported a 57-year-old female patient with multiple radiopaque lesions affecting right maxillary second...
