The present study was performed in order to examine the composition of the connective tissue that forms an attachment to a dental implant. 6 beagle dogs were used. All mandibular premolars were extracted. After 3 months of healing, 6 fixtures – 3 in each side of the mandible – (Astra Tech Implants, Dental SystemA TiO blast ; Astra Tech AB, Mölndal, Sweden) were installed. After another 3 months...

In order to test the feasibility of transplantation whip black coral species Cirrhipathes anguina (Dana, 1846) from Madagascar, transplants were installed on cultivation tables in two sites (the North Pass and Grande Vasque) characterized by distinct environmental conditions. Following transplantation, followed for short-term (20 days) healing capacities medium-term (200 mortality growth rates....

abstract background: pressure ulcer is one of the main concerns of nurses in medical centers around the world, which, if untreated, causes irreparable problems for patients. in recent years, nitric oxide (no) has been proposed as an effective method for wound healing. this study was conducted to determine the effect of nitric oxide on pressure ulcer healing. materials and methods: in this clini...

introduction: the purpose of this in vitro study was to investigate the influence of 5.25% sodium hypochlorite (naocl) and 0.12% chlorhexidine gluconate (chx) use separately and combined as endodontic irrigants on the apical sealing ability of two endodontic sealers. materials and methods: eighty-six extracted maxillary central incisor teeth were used. the teeth were decoronated at the cej, acc...

Extrusion of root filling material had been shown to reduce the success endodontic treatment. This case report describes management a patient who reported prolonged, persistent, and increasing pain on an upper filled central incisor with extruded material. A 28-year-old female came chief complaint tenderness left incisor. The was mostly triggered by mastication. Upon examination investigation, ...

Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...

The objective was to evaluate the clinical efficacy of chemomechanical preparation of the root canals with sodium hypochlorite and interappointment medication with calcium hydroxide in the control of root canal infection and healing of periapical lesions. Fifty teeth diagnosed with chronic apical periodontitis were randomly allocated to one of three treatments: Single visit (SV group, n = 20), ...

PURPOSE The aim of the present exploratory study was to evaluate extraction socket healing at sites with a history of periodontal and endodontic pathology. METHODS The mandibular 4th premolar teeth in 5 adult beagle dogs served as experimental units. Periodontal and endodontic lesions were induced in 1 premolar site in each animal using wire ligatures and pulpal exposure over 3 months (diseas...

Purpose The aim of this prospective pilot study was to compare alveolar ridge preservation (ARP) procedures with open-healing approach using a single-layer and a double-layer coverage with collagen membranes using radiographic and clinical analyses. Methods Eleven molars from 9 healthy patients requiring extraction of the maxillary or mandibular posterior teeth were included and allocated int...

INTRODUCTION Apical periodontitis (AP) is an inflammatory response that can affect the maxillary sinus. This study characterized maxillary sinus mucositis adjacent to teeth with AP and assessed its resolution after endodontic treatment. METHODS Thirty maxillary sinuses in subjects (n = 29) who had AP associated with maxillary posterior teeth were imaged with cone-beam computed tomography (CBC...
