After tooth extraction, the alveolar ridge will commonly decrease in volume and change morphologically. These changes are usually clinically significant and can make placement of a conventional bridge or an implant-supported crown difficult. If bone resorption is significant enough, then placement of an implant may become extremely challenging. Postextraction maintenance of the alveolar ridge m...

The alveolar bone undergoes a remodelling process after tooth extraction, which leads to horizontal and vertical loss. These resorption processes complicate dental rehabilitation, particularly in connection with implants. Clinical studies have suggested that retaining roots of hopeless teeth may avoid tissue alterations extraction. aim is seal the surgical site following outline extraction sock...

Background: Bone resorption due to tooth extraction leads unpredictable bone volume for future prosthetics. Crab shells were promoted as a solution prevent resorption, along with an effort reduce biological waste. Purpose: This study aimed analyze the expression of sialoprotein (BSP) and dentine matrix protein-1 (DMP1) in wound healing process tooth-extraction sockets after applying crab shell-...

BACKGROUND following tooth extraction and immediate implant installation, the edentulous site of the alveolar process undergoes substantial bone modeling and the ridge dimensions are reduced. objective: the objective of the present experiment was to determine whether the process of bone modeling following tooth extraction and immediate implant placement was influenced by the placement of a xeno...

BACKGROUND The theropod dinosaur family Troodontidae is known from the Upper Jurassic, Lower Cretaceous, and Upper Cretaceous of Asia and from the Upper Jurassic and Upper Cretaceous of North America. Before now no undisputed troodontids from North America have been reported from the Early Cretaceous. METHODOLOGY/PRINCIPAL FINDINGS Herein we describe a theropod maxilla from the Lower Cretaceo...

OBJECTIVE The objective of this study was to estimate the frequency of postoperative lingual nerve (LN) impairment after the surgical removal of mandibular third molars (M3) and to identify potential risk indicators. SUBJECTS AND METHODS A prospective cohort study involving 321 subjects who had 443 mandibular M3 surgically extracted at the University Hospital, Amman, Jordan. Predictor variabl...

A novel chitosan-γPGA polyelectrolyte complex hydrogel (C-PGA) has been developed and proven to be an effective dressing for wound healing. The purpose of this study was to evaluate if C-PGA could promote new bone formation in the alveolar socket following tooth extraction. An animal model was proposed using radiography and histomorphology simultaneously to analyze the symmetrical sections of W...
