Abstract:

A new era in 3-dimensional analysis has begun with the use of cone-beam computed tomography (CBCT) in orthodontics, which promises to provide a more thorough understanding of the craniofacial skeletal architecture. This study aimed to investigate the correlation between the transverse basal arches discrepancy and dental compensation by utilizing CBCT width analysis. An observational study was conducted to retrospectively review 88 CBCT scans of patients presented to dental clinics from 2014 to 2020 obtained from the Planmeca Romexis x-ray system at three centers.

Objective: Taurodontism is a developmental disorder with enlargement of the body of the tooth and lack of cervical constriction, which results in a large pulp chamber and small roots with the apical displacement of furcation. Taurodontism exists in deciduous, and definitive unilateral, and bilateral teeth. We found that taurodontism was also described in 67 syndromes.

Abstract:

Typically, maxillary second molars have a different number, size, and arrangement of cusps than molar teeth, which have four cusps and a square occlusal surface. Mandibular molars are considerably less likely to have an oblique ridge, and buccal accessory cusps are very rare. This case study aimed to describe a unique case of a permanent maxillary second molar and a permanent mandibular first molar with an oblique that resembled the maxillary molar crown.

Abstract:

Maxillary molar distalization to correct a dental Class II molar relationship and to create space to relieve crowding has been a long-lasting subject of debate in orthodontics. Generally, to distalize maxillary molars, an intra-arch distalization appliance is favored over an inter-arch appliance since it does not utilize mandibular dentition as an anchorage, so some unwanted side effects on mandibular incisors can be avoided. A variety of intra-arch appliances have been developed to distalize maxillary molars, such as the pendulum, Jones jig, first class appliance, distal jet, and modified C-p

Abstract:

Ameloblastic fibroodontoma (AFO) is a rare entity of mixed odontogenic tumors and frequently arises from posterior portion of the maxilla or mandible in first two decades of life. Herein, a 35-year-old woman with a noncontributory medical history who presented with a progressive left maxillary toothache, left maxillary first molar tooth mobility, and swelling in the left maxillary molar area for the last 2 months was reported. Radiologically, a tumor that originated from periapical area of the second mature molar teeth of maxilla was seen and additively unerupted tooth was not detected. The hi

Abstract Objective: To quantify the treatment effects of interradicular miniscrew anchorage and to confirm the validity of the clinical usage of interradicular miniscrews in the distal movement of maxillary molars in nonextraction treatment. Materials and Methods: Twenty-four maxillary molars were moved to the distal using miniscrews placed in the interradicular space between the second premolar and the first molar at an oblique angle of 20 to 30 degrees to the long axis of the proximal tooth. The teeth were evaluated as to how the molars were moved to the distal with the use of lateral cephal

ABSTRACT The clinician must be familiar with the morphology of the roots of all teeth and the associated intricate root canal anatomy to achieve proper access to the canals, effective debridement, and obturation for successful endodontic treatment. These case reports intensify the complexity of maxillary molar morphologic variation and represent successful endodontic treatment of maxillary 1st molars with six canals and maxillary 2nd molar with two palatal canals, which is rarely discussed in literature.

Deeper understanding of root canal anatomy is fundamental for successful endodontic treatment. Two palatal roots in maxillary second molars, although uncommon, can be encountered in clinical practice. Advanced diagnostic tools like cone beam computed tomography (CBCT) plays a pivotal role in identification and management of this type of complex anatomy. This case report presents endodontic management of maxillary second molar with two palatal canals using CBCT and magnification.Keywords: Dental Pulp Cavity, Maxillary Molar, Palatal Canals, Tooth Root, 3D imaging

Background. Stainless steel crowns (SSCs) of the opposing maxillary deciduous molar teeth are used in mandibular deciduous first molars with decreased proximal surfaces due to caries. However, the SSCs of maxillary deciduous molar teeth are different from those of the mandibular deciduous molars in terms of the occlusal surface morphology, the buccal margin, and the proximal surface contour. Therefore, it is possible to prepare the buccal and lingual surfaces to use the SSC of the lower deciduous molar teeth and compare microleakage. Methods.
