Molar cusps in Southern Chinese

Aim: To investigate the number of molar cusps of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The number of molar cusps of study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: For upper first molars, 5-cusp molars were the most prevalent in males (39%) while 4-cusp molars were the most prevalent in females (39%). For lower first molars, 5-cusp molars were the most prevalent in both sexes (63%-72%). For lower second molars, 5-cusp molars were the most prevalent in both sexes (43%-53%). Conclusion: Different from traditionally described, the Southern Chinese has more 5-cusp lower second molars than the 4- cusp ones.published_or_final_versio

Temporomandibular joint remodeling for the treatment of temporomandibular joint disorders: a clinical case study

Introduction: The author (R. Wurgaft) has tried a unique way of splint therapy in the treatment of temporomandibular disorder. An orthopedic splint that only contact in the posterior occlusion, actually only the most distal contacts, is designed to distalize the mandible, and in turn to produce tissue remodeling of the temporomandibular joint. With this technique, it is possible to treat temporomandibular disorders in both adults and children by producing tissue remodeling. Method: Two clinical cases using this technique were performed. Result: improvement in temporomandibular disorder was obtained. Conclusion: It is possible for orthopedic splint with medial and posterior contacts only to produce TMJ remodeling in young and adult patients and to improve the TMD. Further clinical studies are warranted.published_or_final_versio

Incisal Morphology of Southern Chinese

Aim: To investigate the dental morphology of incisors of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The dental morphology of study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: The moderate types of shovel-shaped central incisors were prevalent in the Southern Chinese, whereas the pronounced type of shovel-shaped incisors were more prevalent in the Taiwan Chinese. Conclusion: The Southern Chinese shows a lesser degree of shoveling than the other Chinese populations.published_or_final_versio

Incisor winging in Chinese

Aim: To investigate the incisor wingings of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The maxillary and mandibular incisor alignment in study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: The prevalence of bilateral winging in the maxillary arch was 9% for males and 10% for females respectively. The prevalence of bilateral winging of the mandibular incisors was higher than the maxillary central incisors, at a prevalence of 22% for both sexes. Bilateral counter-winging of the central incisors was rare. Conclusion: The prevalence of bilateral winging or mesio-palatal rotation of upper central incisors was between low and intermediate in the Southern Chinese. On the contrary, the prevalence of counter-winging was low.published_or_final_versio

Management of severe Class II malocclusion with sequential removable functional and orthodontic appliances: a case for MorthRCSEd examination

INTRODUCTION: Functional appliances are an effective way of treating skeletal Class II malocclusion in children and adolescents. A 12 month step-wise mandibular advancement protocol has been proved to enhance the condylar growth and improve the mandibular prognathism using Herbst appliance. OBJECTIVES: The following case report documented a 11 year-old Chinese girl with 11 mm overjet treated by a Phase I 12-month growth modification therapy using Twin Block appliance with Hyrax palatal expander and high pull headgear in a step-wise mandibular advancement protocol followed by a Phase II preadjusted Edgewise appliance therapy. This is one of the cases submitted for the Membership of Orthodontics Examination of the Royal College of Surgeons of Edinburgh.published_or_final_versio

Orthodontic tooth movement of total buccally blocked-out canine: a case report

Orthodontic tooth movement of total buccally blocked-out canine is usually difficult as it is related with the problems of severe crowding, midline deviation, involvement of long root movement and risk of gingival recession. A case report was presented to illustrate the treatment principles. It demonstrated with careful planning in extraction sequence and orthodontic mechanics to deliver light, controlled force, condition of totally blocked out canine could be corrected with good results.published_or_final_versio
