Head and neck cancer is treated with radiotherapy that, while effective against the tumor, profoundly damages the surrounding healthy oral tissues. One of the most challenging long-term complications is radiation caries, a rapidly progressive form of tooth destruction that can devastate the denti...

Pericoronitis is an acute infection of the soft tissue surrounding a partially erupted tooth, and it most often affects the mandibular third molar. It is a common reason for emergency dental attendance, causing pain, swelling, trismus, and occasionally serious spread of infection into the deep ne...

Eagle syndrome, also known as stylohyoid syndrome or styloid process syndrome, is an under-recognized cause of chronic pain in the throat, face, and neck. It arises when an abnormally elongated styloid process or a calcified stylohyoid ligament compresses nearby neurovascular structures. Because ...

Dens invaginatus, also known as dens in dente, is a developmental dental anomaly in which the enamel organ invaginates into the dental papilla before mineralization. The result is a tooth that contains a deep pit or a pouch lined with enamel, often reaching far into the crown or even the root. Al...

Cherubism is a rare, hereditary bone disorder of childhood that causes progressive, painless swelling of the jaws. Because the full cheeks and upturned eyes of severely affected children resemble the cherubs depicted in Renaissance paintings, the condition received its distinctive name. Although ...

<p class="lead">For decades, the only response to a carious lesion was to drill and fill it, removing tooth structure to place a restoration. Resin infiltration offers a different philosophy: instead of removing the lesion, it stops the lesion from progressing by sealing it from within. This mini...

<p class="lead">When a primary tooth is severely decayed or damaged, a simple filling is often not enough to restore its function and keep it healthy until it exfoliates naturally. Preformed crowns provide a durable, full-coverage restoration that protects the tooth and maintains space in the arc...

<p class="lead">After months or years of active orthodontic treatment, the teeth are aligned, the bite is corrected, and the braces come off. Yet the treatment is not finished: without retention, the teeth will drift back toward their original positions. Relapse is a natural consequence of the el...

<p class="lead">Primary herpetic gingivostomatitis is the first infection of the mouth with the herpes simplex virus, and it is one of the most painful conditions a child can experience.

<p class="lead">When a tooth with an apical infection fails to heal after root canal treatment, the endodontist has a limited number of options: retreat the tooth, extract it, or perform periradicular surgery. Apicoectomy, the surgical removal of the root tip and the infected tissue around it, of...

<p class="lead">Osteoradionecrosis of the jaws is one of the most feared complications of radiotherapy for head and neck cancer. It presents as exposed, non-healing bone within the radiation field, causing pain, infection, and fistula formation, and it can severely impair the patient's quality of...

<p class="lead">Mucocele and ranula are the two most common benign lesions of the minor and sublingual salivary glands. Both arise from the obstruction or rupture of a salivary duct, producing a fluid-filled swelling that is usually painless but cosmetically and functionally troublesome. This art...

<p class="lead">Injury to the inferior alveolar or lingual nerve is among the most feared complications in dentistry, producing numbness, tingling, or altered sensation in the lip, chin, and tongue that can persist for months or years. Although rare, these injuries cause significant distress and ...

<p class="lead">The success of a composite restoration depends less on the resin itself than on the quality of the bond between the material and the tooth. Modern adhesive systems have transformed restorative dentistry by making micromechanical attachment to enamel and dentine predictable and dur...

<p class="lead">Bitewing radiographs are the single most valuable imaging tool for the detection of caries, particularly the interproximal lesions that are invisible to the naked eye and frequently missed on clinical examination alone. Yet their use must be balanced against radiation exposure and...

<p class="lead">Premature loss of a primary tooth is one of the most common problems managed in pediatric dentistry, and the consequences of failing to act can be seen years later as crowding, impaction, and malocclusion. Space maintainers are appliances designed to preserve the space left by an ...

<p class="lead">Sialolithiasis is the most common disease of the major salivary glands, characterized by the formation of calcified stones within the salivary duct system. The condition produces recurrent swelling and pain of the affected gland, particularly at mealtimes, and can progress to seco...

<p class="lead">Recurrent aphthous stomatitis, commonly known as canker sores, is the most frequent ulcerative disease of the oral mucosa, affecting an estimated 20% of the general population.
