Squamous cell carcinoma is not a single, uniform disease, and two of its oral variants illustrate the extremes of its behavior. Verrucous carcinoma is a slow-growing, exophytic tumor that almost never metastasizes, while spindle cell carcinoma is an aggressive, sarcomatoid malignancy that can be ...

Most people expect a toothache to be the first sign of pulp disease, but some forms of pulpitis are surprisingly silent. A pulp polyp is the visible result of chronic hyperplastic pulpitis, a condition in which the dental pulp grows out of a large carious opening as a fleshy mass. Recognizing thi...

Dry mouth is not merely uncomfortable; it is a medical condition with real consequences for teeth, speech, swallowing and quality of life. When the salivary glands cannot produce enough saliva, medications called sialogogues can restore some of the missing fluid. Pilocarpine and cevimeline are th...

A blister in the mouth can be the first warning of a systemic autoimmune disease, and two disorders deserve particular attention in the dental chair: pemphigus vulgaris and mucous membrane pemphigoid. Both produce chronic oral ulceration, yet their immunologic targets, clinical behavior and long-...

When infection drains from a tooth, the body often creates a visible escape route, and the dentist must interpret these fistulous openings correctly. A parulis is the common gum boil that signals chronic periapical infection, while an oroantral fistula is a communication between the mouth and the...

Among the fibro-osseous lesions of the jaws, the ossifying fibroma holds a unique position because it is a true neoplasm, unlike the reactive cemento-osseous dysplasia discussed in an earlier article. It grows continuously, expands bone and requires surgical removal, and its cemental variant adds...

Not all keratocystic lesions of the jaw behave alike, and one of the most important distinctions in oral pathology separates the orthokeratinized odontogenic cyst from its better-known relative, the odontogenic keratocyst. Although the two lesions look similar under the microscope at first glance...

Periodontal disease is usually a slowly progressive infection, but a rare form called necrotizing ulcerative periodontitis destroys tissue with alarming speed. Unlike ordinary periodontitis, this condition produces necrotic, cratered papillae, deep pocketing and rapid bone loss, and it appears al...

Every parent has met the child who refuses to eat because of painful mouth sores, and most of these children have one of two viral illnesses: herpangina or hand, foot and mouth disease. Both are caused by enteroviruses, both produce fever and oral ulcers, and both are overwhelmingly common in you...

Cementoosseous dysplasia is one of the most common fibro-osseous lesions found on dental radiographs, yet it is also one of the most frequently misdiagnosed. The lesion replaces normal bone with cellular fibrous tissue and cementum-like material, and it appears in several forms that range from a ...

Thumb sucking and pacifier use are normal self-soothing behaviors in infancy, and most children give them up on their own by school age. The dental problem arises when the habit continues past the eruption of the permanent front teeth, because the persistent pressure reshapes the growing jaw and ...

Most people never think about the shape of their tooth roots, but root morphology determines how a tooth is treated when disease strikes. Taurodontism and dilaceration are two developmental anomalies that change root anatomy in distinctive ways, and both have major implications for endodontics, e...

Dental injuries are among the most common sports-related injuries, and a mouthguard is the simplest piece of equipment an athlete can wear. Yet many players still train without one, often because they have never been told which type to choose or how a well-fitted guard feels. Understanding the pr...

Piezoelectric surgery has changed the way oral surgeons cut bone. Instead of a rotating bur, a piezotome uses ultrasonic vibrations to cut mineralized tissue while leaving soft tissue largely untouched. The technique is now routine for osteotomies, sinus lifts and delicate procedures where precis...

Children's teeth vary naturally in size, but some variations are large enough to affect function, appearance and future orthodontic care. Microdontia means teeth that are smaller than normal, and macrodontia means teeth that are larger than normal, and both can appear as isolated findings or as p...

Two patients can have identical teeth and completely different treatment outcomes, and the reason is often hiding in the gums. Gingival biotype describes the thickness and morphology of the soft tissue around the teeth, and it influences how the gum reacts to surgery, implants, braces and even si...

Guided bone regeneration, or GBR, is the standard method for rebuilding bone before and around dental implants. The concept is simple: a membrane creates a protected space that allows bone-forming cells to grow while excluding competing soft tissue. Choosing a resorbable membrane changes the prot...

Periodontal disease destroys not only the gum but the bone and ligament that anchor teeth, and the goal of regenerative treatment is to rebuild all three. Emdogain, an enamel matrix derivative, has become one of the most studied biological agents for this task, and its results improve further whe...

A chipped tooth is one of the most common dental emergencies, affecting children and adults alike through falls, sports, biting on hard objects and even normal wear. The right repair depends less on the size of the fragment and more on which layer of the tooth is exposed. Bonding, veneers and cro...

A knocked-out tooth is one of the few dental emergencies where minutes decide the outcome. When a permanent tooth is completely displaced from its socket, immediate and correct handling can save it, while delays or mistakes can condemn it to loss. The steps are simple enough for any parent, coach...

Wisdom teeth, or third molars, are the last teeth to erupt, and a large proportion of them never achieve a functional position. When a wisdom tooth is trapped beneath the gum or bone, it is described as impacted, and the decision to remove it is one of the most common surgical judgments in dentis...
