For sure Impression materials are related and integrated in the dentistry field. That’s why we observe so many changes in the materials itself just like the polyether and additional silicone. Briefly, impression materials are divided into rigid and elastic impression materials in which generally the rigid one is used for edentulous patients with mild or moderate undercuts whereas the elastic one is used for dentulous or edentulous patients with severe undercuts. Now both polyether and additional silicone (PVS) are subgroups of the elastomeric elastic impression materials and have a variety of functions and properties which distinguish each other.
In a world of social media and smartphones, we are only ever one click away from a photo being snapped and shared with the world. It is making people more aware than ever of how their teeth – and their smiles – look…
To many patients, pain and dentistry are synonymous. Patient surveys continue to indicate that fear of pain prevents many patients from scheduling dental appointments. This can often lead to the progression of infection or dental disease. Equally important, clinical practice can be disrupted by unscheduled emergencies and possible difficulty in obtaining adequate pain control. Challenges in this area can be a source of frustration to the busy practitioner, and perhaps even more so for the anxious patient. This does not have to be the case. Research conducted by endodontists and other clinicians interested in pain management have revolutionized our ability to treat acute inflammatory pain.
It is interesting to note that some dentists have patients who complain of postoperative tooth sensitivity frequently, while others do not. The question you asked is not a new one; it has been asked for several decades. Scientists and clinicians in our research organization, Clinicians Report Foundation (CR Foundation), have researched this topic for many years.

Minimally invasive restorative techniques are becoming more prevalent as a philosophy and treatment modality. Even so, many dentists still diagnose pit-and-fissure caries with an explorer, the same explorer that is now a blunt probe after being sterilized hundreds of times!
There are two basic ways to increase profitability in the dental office-work harder or work smarter. Working harder means seeing more patients, doing more procedures, and practicing at a faster pace. Working smarter includes increasing efficiency of personnel, technology, and supplies. The two are not the same, and do not always mean working faster.
It’s not uncommon for patients who are middle-aged or older to present with multiple failing amalgam restorations in a single quadrant. Many of these restorations can be replaced conservatively with direct composite. Unfortunately, however, many of the placement and accompanying adhesive protocols required for predictability can be time-consuming and technique sensitive. That’s why it’s important to understand the historical development of adhesive dentistry when considering today’s etching and adhesive protocol options to determine which will serve you and your patients best.
is a term that describes a broad continuum of breathing abnormalities that occur during sleep. On one end of the spectrum, mild narrowing and/or laxity of the airway tissues may first present as snoring. This is sometimes termed “benign snoring” because it does not cause sleep disturbances. However, snoring alone may increase a patient’s risk for stroke, so it is difficult to know for certain if any amount of snoring is “benign.” Next on the continuum is upper airway resistance syndrome (UARS). This occurs when the narrowing of the airway causes increased effort to breathe. This phenomenon can cause poor sleep quality, morning headaches, insomnia, and mood disturbances, among other problems. It is important to note that not all patients with UARS snore and not all patients even realize they sleep poorly. It is possible to be asleep the whole night, but not get into deeper, more restorative sleep because the body is fighting to keep the airway open. When the airway narrows to a point that oxygen saturation in the body is significantly affected, the patient has obstructive sleep apnea-hypopnea syndrome (OSAHS). A hypopnea is a partial narrowing of the airway for a minimum time associated with a certain oxygen saturation drop. An apnea is a complete or almost complete blockage of the airway for a certain time.
The term desquamative gingivitis (DG) describes a clinical condition in which the gingival tissues are erythematous, blistering, and eroding. It is not a diagnosis but is instead a term applied to the manifestation of a multitude of mucocutaneous, systemic, allergic, and immunologic diseases. The majority of cases are caused by oral lichen planus, pemphigus vulgaris, and mucous membrane pemphigoid, but many less common sources need to be considered in the differential diagnosis as well. These include erythema multiforme, lupus erythematosus, drug-induced lesions, graft versus host disease, chronic ulcerative stomatitis, plasma cell gingivitis, linear IgA disease, dermatitis herpetiformis, psoriasis, epidermolysis bullosa acquisita, paraneoplastic and neoplastic disorders, and allergic reactions. The dental clinician can play a crucial role in the diagnosis of these conditions, some of which can cause significant morbidity and even mortality.
In dentistry, nitrous oxide is the most commonly used inhalation anxiolytic and sedation adjunct. It reduces anxiety and pain, and memory of the treatment experienced. It is a valuable component of the armamentarium available to clinicians. When used correctly, it is predictable, effective, and safe.
