Orthognathic Surgery for the Correction of Severe Skeletal Class III Malocclusion.

Skeletal Malocclusions results from the abnormal position of maxilla and mandible in relation with cranial base. These types of malocclusion are commonly treated by orthodontic teeth movement known as camouflage orthodontics. However severe skeletal malocclusions cannot be treated by orthodontics alone. Such cases need surgical intervention to align the position of the jaw along with orthodontic correction. This procedure is commonly known as Orthognathic Surgery. Orthognathic Surgery dates back to early eighteenth century but became popular on mid twentieth century. Though the prevalence of skeletal malocclusion is more than 1% the treatment facility was not available in Nepal till 2012. Here we present a case of Skeletal Class III malocclusion treated at Dhulikhel Hospital, Kathmandu University Hospital. For this case, double jaw surgery was performed by le-Fort I osteotomy and Bilateral Sagital Split Osteotomy. Orthognathic surgery has been routinely performed at this centre since then.

Knowledge of emergency management of avulsed teeth among general dentists in Kathmandu.

BACKGROUND: An avulsed permanent tooth is one of the most emergency situations in dentistry. Dentists handling the situation should have adequate knowledge in this field. OBJECTIVE: To assess the level of knowledge of emergency management of avulsed teeth among general dentists in Kathmandu. METHODS: A questionnaire containing 10 close ended questions about emergency management of avulsed teeth was distributed among 102 general dental practitioners working in different private dental hospitals and clinics of Kathmandu. The dental hospital and clinics were randomly selected. This cross sectional study was conducted between January 2012 to February 2012. RESULTS: Among the studied group, almost all of the participants, 98(96.1%) said that an avulsed permanent tooth cannot be replanted in all cases. Majority of them, 63 (61.8%) said that the critical time for the replantation is within 20 minutes. General dentists of Kathmandu did not have adequate knowledge about emergency management of avulsed teeth. CONCLUSION: An education program should be conducted to increase the knowledge of general dentists in the management of traumatic injuries to teeth.
