The management of children born with cleft lip and palate

Although cleft lip and palate is a single anomaly, its consequences affect several systems and functions of the child as well as the social and psychological problems that impact on the child and parents. Therefore, the services of a team of specialists are required to care for a child with cleft lip and palate. Empathic counselling and help with feeding ensures that the infant can cope with the primary surgery to the lip and palate. If speech problems occur, a nasendoscopy can be performed to determine the nature of the speech abnormality and to assess the appropriateness of additional palatal surgery. Nasendoscopy may also be required later because osteotomy surgery can compromise speech. Alignment of the teeth may be necessary before bone grafting of the residual alveolar cleft, and is always needed prior to and after orthognathic surgery. The development and regular practice of a range of clinical skills is essential if the team of specialists are to plan and deliver the appropriate high quality care needed by children and adolescents with cleft lip and palate.published_or_final_versio

Alternative donor site for alveolar bone grafting in adults with cleft lip atid palate

Grafting of the alveolar ridge with autogenous bone is an integral stage of contemporary management of complete cleft lip and palate cases. Alveolar bone grafting restores continuity of the dental arch, closes oronasal fistulae, supports the alar base, and facilitates spontaneous eruption of permanent teeth adjacent to the cleft. However, timing of the graft and the selection of materials have been topics of much debate in the literature. This article discusses an alternative donor site in cases where rehabilitation has passed the recommended time. Harvesting bone from the third molar regions allows not only the removal of impacted third molars during the same surgical procedure, but also eliminates the morbidity associated with additional surgical sites such as the ilium or mandibular symphysis. This report should not be interpreted as a recommendation for the use of this alternative site in cases where grafting is carried out within the optimal time period, which is usually in the mixed dentition stage. However, when grafting is necessary in young adults suffering from complete cleft lip and palate, the third molar region may provide another acceptable donor site.link_to_OA_fulltex

Correlation of orthodontic treatment demand with treatment need assessed using two indices

The orthodontic treatment need of 105 first year university students (51 males and 54 females, mean age 19.75 years) at the University of Hong Kong was assessed using the Occlusal Index (OI) and the Index of Orthodontic Treatment Need (IOTN). The results were compared with the subjects' orthodontic treatment demand derived from a questionnaire. The OI assessment correlated better with the individuals' own perceptions of appearance than did the IOTN, and the treatment need indicated by the OI also correlated better with the individuals' actual treatment demands.link_to_OA_fulltex

A comparative study of sagittal correction with the Herbst appliance in two different ethnic groups

The dentofacial morphology of Chinese is different from Caucasians. The purpose of this investigation was to assess the skeletal and dental changes contributing to the sagittal correction in a group of consecutive Chinese children who were treated with the Herbst appliance. A comparison was made between 14 Chinese and 14 Swedish subjects who all had Herbst appliance treatment. All subjects were corrected from the Class II division 1 malocclusion to an overcorrected Class I or Class III dental relationship within a 6-8 month period. Lateral cephalograms taken before and immediately after the Herbst treatment were analysed. In general, the skeletal and dental changes during treatment were comparable between both ethnic groups. However, individual variations within the two groups were wide. It can be concluded that the Herbst appliance was equally successful in Southern Chinese children and similar treatment changes as those achieved in Swedish children could be found.link_to_OA_fulltex
