A Narrative Review of Osteonecrosis of the Jaw: What a Clinician Should Know.

Medication-related osteonecrosis of the jaw (MRONJ) is an uncommon complication of antiresorptive therapy (ART) in patients receiving higher and more frequent doses of osteoclast inhibitors. The jaws are the most common site, as they have high bone turnover. The oral structures are exposed to various types of stresses, like mastication and dental diseases, which lead to microtrauma and increased bone remodeling. The hallmark feature of MRONJ is the area of exposed, necrotic, nonhealing, asymptomatic bone for more than eight weeks. Objective signs are pain in the jaw and oral cavity, loose teeth, gingival swelling, ulceration, soft tissue infection, and paresthesia in the trigeminal nerve branches' territory. Clinically, the MRONJ has been defined in four stages, from stage 0 to stage 3. Close coordination between the dentist and oncologist is critical for optimal treatment. Conservative management should be preferred over surgical management. There is significant underreporting and misdiagnosis of MRONJ cases in regular clinical practice. There needs to be more awareness among treating physicians about this sporadic complication of bisphosphonate therapy. This narrative review has given a detailed insight into the subject, starting with etiology, pathogenesis, incidence, clinical presentation, workup, staging, and various management strategies. The review article focuses mainly on practical aspects of MRONJ, which every clinician dealing with the disease must know. With a better awareness of this potential complication, healthcare practitioners dealing with at-risk patients can better diagnose, prevent, address, and provide necessary care.

Naso-alveolar molding for newborn cleft lip and palate.

The nasoalveolarmolding (NAM) technique is a relatively new approach to pre-surgical infant orthopedics that reduces the severity of the initial cleft alveolar and nasal deformity before surgery. This technique has proved to be an effective adjunctive therapy for reducing cleft deformity before surgery. Data on NAM are inconsistent with changes in nasal symmetry. However, there is a trend towards a positive effect. Therefore, it is of interest to report clinicians an overview of NAM appliance and method for nasal symmetry assessment to facilitate greater usage of this technique in contemporary practice. Thus, the biomechanics of pre-surgical infant orthopedics and of nasal stent that skillfully shape alveolus and nasal cartilage is explained.
