What Is A Dental Abscess? What Causes Dental Abscesses?Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A dental abscess, or tooth abscess, is an accumulation of pus that forms inside the teeth or gums. The abscess typically originates from a bacterial infection, often one that has accumulated in the soft pulp of the tooth. Bacteria exist in plaque, a by-product of food, saliva and bacteria in the mouth which sticks to the teeth and damages them, as well as the gums. (Source: Dentistry News From Medical News Today)

Hybrid Composite For Root Canal TreatmentEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Unrelenting toothache means a visit to the dentist is inevitable, and if the tooth decay is really bad root canal treatment is often the only option. The dentist first removes the nerve completely and then closes the ensuing canal with a filler. This must be airtight to prevent bacteria from entering and causing renewed inflammation. On the other hand, the material must also be removable. (Source: Dentistry News From Medical News Today)

Evaluation of the radiopacity of calcium silicate cements containing different radiopacifiersEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions Silver/tin alloy and gold powder imparted the necessary radiopacity to a calcium silicate-based cement. Barium sulphate was also a suitable radiopacifier together with a lower concentration of silver/tin alloy and gold powder that achieved the radiodensity recommended by ISO 6876. Further research is required to investigate the broader properties of the calcium silicate-based cement with the different radiopacifiers. (Source: International Endodontic Journal)

Stability values of titanium dioxide-blasted dental implants in edentulous maxillas: a 3-year pilot studyEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Summary The purpose of this follow-up study was to measure the resonance frequency of Astra Tech TiO2 blasted implants at second surgery, at one and 3 years of loading. Secondly, it was investigated whether resonance frequency at second surgery could discriminate between successful implants and those that will fail over a 3-year period. Fifty titanium dioxide-blasted implants in eight consecutive patients with edentulous maxillas seeking fixed rehabilitations, were included in the study at abutment connection after 6 months of healing. Resonance frequency, clinical and radiographic records were obtained at abutment connect...

Dentin strain induced by laser irradiationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of this study was to investigate the strain and temperature change in dentin induced by laser irradiation of human root canals with or without water cooling. Twenty-eight palatal roots of extracted human maxillary first molars were used. The strain in dentin was measured using strain gauges fixed on the apical third of the buccal root surface. The temperature change of the root dentin was monitored using thermocouples embedded into dentin near the apex. The root canal was irradiated with Er:YAG or Nd:YAG laser at an output of 1 W (100 mJ, 10 pps) for 5 s. The tip of the irradiation fibre was located 2.0 mm from...

This study assessed if residues from MTAD, Endo-CHX, Peridex Oral Rinse or 6% NaOCl were inactivated by exposure to simulated leakage. Extracted teeth (15/group) were cut and drilled to produce a cylindrical canal space. They were irrigated, dried with paper points and transferred into 1 mL of simulated leakage (Enterococcus faecalis in tryptic soy broth) every 24 h. After one, two or three transfers, the number of colony forming units was measured by drilling the canal space and recovering the dentine shavings in antimicrobial-inactivating broth. Two-way anova of the log-transformed data showed irrigation method, leakage ...

Intraoral Luting: Modified Prosthetic Design to Achieve Passivity, Precision of Fit, and Esthetics for a Cement-Retained, Implant-Supported Metal-Resin-Fixed Complete DentureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
An intraoral luting technique between electroformed gold copings and a metallic framework for a cement-retained, implant-supported metal-resin-fixed complete-denture is presented. The peculiarity is the different prosthetic design with the metallic framework that was 1.5 mm shorter than the margin of the electroformed copings. As a consequence, the conventional thick prosthesis margin (electroformed copings, cement for the luting phase, framework) was modified into a thin electroformed prosthesis seal (0.3 mm) just beyond the apical limit of the esthetic material. Passive fit between the framework and the electroformed gol...

Microstomia presents a unique challenge to the patient. Patients with microstomia who must wear removable dental prostheses often face the difficulty of being unable to insert or remove the prosthesis because of the constricted opening of the oral cavity.

Abstract The aim of this study was to compare the histologic response elicited by repairing furcal perforations with mineral trioxide aggregate (MTA) and a new endodontic material in the name of “calcium enriched mixture (CEM) cement” in dogs’ teeth. Thirty-four premolars were randomly divided into four groups: MTA (n = 15), CEM (n = 15), positive, and negative controls (n = 4). Root canal therapy were carried out; perforations were made, and the furcation areas were then repaired with MTA or CEM cement. The animals were sacrificed after 3 months. The teeth and their adjacent structures...

Summary The aim of the present study was to determine in humans whether local anaesthesia (LA) or nociceptive stimulation of the periodontal ligaments affects the excitability of the face primary motor cortex (MI) related to the tongue and jaw muscles, as measured by transcranial magnetic stimulation (TMS). Twelve healthy volunteers (11 men, 1 woman, 25·3 ± 4·2 years) participated in two 3-h sessions separated by 7 days. The LA carbocain or the nociceptive irritant capsaicin was randomly injected into the periodontal ligament of the lower right central incisor.

In conclusion, the modified Symptom Severity Index has excellent psychometric properties for use as an instrument to measure pain in subjects with TMD. The most important characteristic of this pain is location, while the temporal dimensions are important for jaw pain. Further research is needed to confirm these findings and assess relationships between dimensions of pain as experienced in other chronic pain disorders. (Source: Journal of Oral Rehabilitation)

Parotid gland swelling following mouthrinse useEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Swelling of the parotid gland following use of a mouthwash has previously been reported, although previous reports found this side effect only in patients who used chlorhexidine mouthwashes. This complication has therefore been informally linked to chlorhexidine. The present case report questions this hypothesis and suggests that parotid gland swelling may not be related to the type of mouthwash used, but may instead be a consequence of the rinsing action itself.

The value of chlorhexidine in clinical dentistry has led to many applications, including varnishes, mouthwashes, sprays, chewing gums, and dentifrices. However, at some common concentrations, it can cause staining, especially in orthodontic patients. The aim of this study was to determine whether a lower concentration of chlorhexidine in dentifrices (0.50% or 0.75%) could reduce the risk of tooth staining without compromising its effectiveness for gingivitis, bleeding, and plaque prevention. For the best possible results, this was a double-blind, randomized controlled trial. Fulfilling the inclusion criteria, 81 volunteers...

Introduction: Mini-implants are placed in restricted sites, requiring an accurate surgical technique. However, no systematic study has quantified technique accuracy to reliably predict the surgical risks. Therefore, a graduated 3-dimensional radiographic-surgical guide (G-RSG) was proposed, and its inaccuracy and risk index (RI) were estimated.Methods: The sample consisted of 6 subjects (4 male, 2 female), who used mini-implant anchorage. Ten drill-free screws (DFS) were placed by using the G-RSG. The central point of the mesiodistal septum width (SW) was the selected implant site on the presurgical radiograph. The distanc...
