摘要:

Abstract—Histological observations in three cases of tooth root displacement to the maxillary sinus show that under certain conditions the root may be accepted by the tissues. General and local factors in the defenco mechanism and the existence or otherwise of periapical pathosis must be considered in determining the treatmen

摘要:

Abstract—The patient complained of temporo‐mandibular joint dysfunction and bad taste. A number of hard black objects clumped together were removed from a large swollen erythematous tonsil. Radiographic examination and electron and optical micrographs demonstrated their structure and density, and an atomic absorption test showed: 10 per cent calc

摘要:

Abstract—The properties of both long‐ and short‐term cementing materials (cemats) are stated. The selection of long terra cemats should be guided by oral conditions and possible pulp reaotions. Provision of escapeways and guide grooves is essential, correct mixing and insertion within proper working time must be followed. Short‐term cemats should be used for chocking seating and occlusion. No perfect long‐term cemat is

摘要:

Abstract—A survey of 48 dental students aged 19–30 years revealed one‐third had or were receiving orthodontic treatment, seven had evidenoe of TMJ dysfunction, four wore bridges or partial dentures, and five needed some prosthesis; the DMFT and S was 14–57 and 26–85 but some of the restorative treatment was defective. Various dental anomalies were present and oral hygiene was similar when compared with other groups. Modified oral hygiene and periodontal disease indices

摘要:

Abstract—Analysis of data available in hospital records in Now South Wales for 1964–1966 shows in 147,042 live births, 192 cleft defects of which 111 wore males. Other congenital anomalies existed in 40 of which 27.3 per cent were associated with isolated cleft palate. There was no seasonal or geographical variation in the distribut

摘要:

Abstract—Three surface treatment agents were applied to specimens of hardened modelling stone and diestone mixed according to instructions. A polystyrene solution had no effect on the hardness, while a concrete hardener and an epoxy resin adhesive softened the surface. Three agents increased resistance to absorption except for the epoxy resin on one of the stones. Film thickness was negligible and no dimensional change was shown with the concrete hardener and polystyrene solutio
