NASAL TEETH - A RARE CASE

                                Eruption of the teeth into the nasal cavity is a rare phenomenon.Ectopic tooth eruption in a non-dental area is a rare entity,  whereas in oral cavity it is most common. The ectopic development of teeth in non-dental localizations have been reported in the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity.


INTRODUCTION : 

Ectopic tooth eruption in a non-dental area is a rare entity, whereas in oral cavity it is most common. The ectopic development of teeth in non-dental localizations have been reported in the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity.

The standard treatment for an ectopic tooth is extraction of the tooth.Facial pain, epistaxis, purulent rhinorrhoea, external nasal deformity, headache, swelling and epiphora related nasolacrimal duct obstruction can be seen.




                                Some of the eruptions may be seen in the sinus's too.



Tooth development results from an interaction between the oral epithelium and the underlying mesenchymal tissue. This process begins in the sixth week in utero with the formation of maxillary and mandibular dental lamina in the region of the future alveolar process. This ectodermal derivative undergoes proliferation to form the permanent dentition between the 5 th and 10 th months, each mature tooth consisting of a crown and a root. Abnormal tissue interactions during development may potentially result in ectopic tooth development and eruption. Ectopic eruption of a tooth into a region other than the oral cavity is rare although there have been reports of tooth in the nasal septum, mandibular condyle, coronoid process . and the palate. Occasionally, the tooth may erupt into the maxillary antrum and present with local sino-nasal symptoms attributed to recurrent or chronic sinusitis. The diagnosis of this condition can be made radiographically with plain sinus X-rays and CT scans taken in axial and coronal sections.

Dentigerous cyst is the most common of all follicular cysts, more common in males, occurring in the second or third decade of life. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla.  If infected, the treatment of choice is complete enucleation of the lesion intraorally with removal of the associated tooth. It is also important to completely remove all diseased antral tissues and thoroughly assess all resected soft tissue histologically. Only a few cases of "ectopic" molars which have been displaced by progressively growing dentigerous cysts have been reported in medical literature.  It is believed that the displacement of tooth buds by the expansion of these dental cysts results in the displacement of the tooth to other areas, which is attributed to the ectopic appearance of the third molar in this patient. Recurrence and malignant or ameloblastic transformation following a dentigerous cyst is rare when compared to odentogenic keratocyst. Close observation and follow-up with periodic radiographs is required.

The treatment of an ectopic tooth in the maxillary sinus is usually removal, as if left untreated, it has the tendency to form a cyst or tumor. Caldwell-Luc procedure was followed in this case as the ectopic tooth was the cause of recurrent sinusitis and purulent rhinorrhea inspite of administering antibiotics repeatedly. The importance of ruling out related dental conditions in any patient presenting with such signs and symptoms of the head and neck region cannot be overemphasized.

Apple Invents a new Health feature for AirPods that will provide diagnosis & monitoring of Bruxism

Today the US Patent & Trademark Office published a patent application from Apple that relates to a possible future health related feature regarding the diagnosis and monitoring of bruxism using motion sensors in AirPods. Teeth grinding and jaw clenching (bruxism) are the most common parafunctional behavior manifested during sleep and awakeness. Awake bruxism has been mostly associated with emotions like anxiety, stress, frustration or tension. During sleep it causes sleep disorders and arousals. Individuals are mostly unaware of the occurrent and severity of their bruxing habits. The unawareness results in a myriad of orofacial muscle pain and dental consequences like teeth damage, wear and fractures. Commercial devices in dental practice to monitor and treat bruxism are expensive, inconvenient for frequent daily use. For instance, Polysomnography (PSG) studies that target the monitoring of sleep bruxism, require patients to sleep in a clinical setting overnight. Further,

Esthetic Oral Rehabilitation with Veneers

Porcelain veneers had long been considered to be only an esthetic solution. However, their range of indications has been steadily increasing, making ceramic veneers a highly viable alternative to classic, far more invasive forms of restorative treatment. Today, veneers can be used to handle esthetics (discolored teeth, fractured and worn teeth, diastemas, dental defects, etc.) and to restore the biomechanics of the dentition, as well as many other indications. Classifications of Veneer Preparations Referred to as no, minimal, or conventional preparation, veneer classifications—or lack there of—create a large gray zone of misunderstanding and miscommunication with patients and within the dental profession. Left unanswered, questions regarding tooth structure removal, finish lines and margins, and other aspects can cause confusion in practice. Flaws and inaccuracies in previously proposed preparation guidelines make those guidelines irrelevant . To dissolve uncertainty, this v

Orthodontics for Esthetic Dental Treatment: Symbiotic Efforts for Optimal Results

Human fascination with beauty and esthetic trends is continuously evolving; moreover, public awareness and desire to improve facial appearances are at the highest level. This trend of heightened public awareness and expectation is paving a new way of dentistry toward a more comprehensive approach with esthetic principles at its core. The oral health of the patient and his or her dentition are fundamental in dental treatment. However, the final esthetic outcome should be among the first steps in treatment planning. The ideal esthetic approach in dental treatment planning often requires a multidisciplinary approach engaging various dental professionals. This process requires thorough communication among dental practitioners and a basic understanding of what each discipline can provide. FACIAL ANALYSIS Facial evaluation is an integral part of patient examination. It starts with evaluating facial symmetry, as symmetric faces are considered more beautiful than those that are n
