Dental anomalies in Chinese children with complete unilateral cleft lip and palate / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the prevalence of dental anomalies in Chinese children with complete unilateral cleft lip and palate (UCLP).</p><p><b>METHODS</b>Dental histories and radiographs of 244 Chinese children with UCLP were collected. The diagnosis of dental anomalies was based on panoramic radiographs before alveolar bone grafting. All patients were over 8 years old.</p><p><b>RESULTS</b>In the UCLP group, 66.8% of the patients was presented with hypodontia. The maxillary lateral incisors were the most common teeth affected, followed by maxillary second premolars, mandibular incisors and mandibular second premolars. A total of 33.6% the patients was presented with dental malformation, most were microdontic laterel incisors. A total of 4.9% the patients was presented with hyperdontia. The supernumerary teeth were more frequently found in the cleft region. The prevalence of missing maxillary lateral incisor in the noncleft side was statistically different between genders, which was higher in male (P < 0.050). This group of Chinese children with UCLP demonstrated significantly higher prevalence of hypodontia, hyperdontia, and malformation on the cleft side than on the noncleft side (P < 0.01).</p><p><b>CONCLUSIONS</b>Hypodontia is the most common type of dental anomalies. The prevalence of dental anomalies is higher in the UCLP patients than in the normal population. Dental anomalies occur more frequently on the cleft side than on the noncleft side.</p>

Preliminary study of Sub-Health Measurement Scale Version1.0 norms for Chinese civil servants / 南方医科大学学报

<p><b>OBJECTIVE</b>To establish the norms of Sub-Health Measurement Scale Version1.0 (SHMS V1.0) for Chinese civil servants.</p><p><b>METHODS</b>We sampled a total of 15 000 civil servants form Tianjin (north China), Guangdong (south China), Anhui and Hunan (central China), Xinjiang (northwest China) and Shenyang (northeast China) to perform the spot trial, and established the mean, percentile and threshold norms based on the characteristics of SHMS V1.0 scores for Chinese civil servants.</p><p><b>RESULTS</b>The established norms based on the average scores of SHMS V1.0 showed a mean score of 66.55∓12.36 for young male subjects (below 40 years), 67.42∓12.40 for older male subjects, 66.22∓11.81 for female subjects younger than 40 years, and 65.94∓11.91 for older female subjects. The threshold norms of SHMS V1.0 divided 5 health states, namely disease, severe sub-health, moderate sub-health, mild sub-health and healthy states according to the Mean∓SD and Mean∓0.5SD of the converted scores. The 4 cut-off points were close to the 15th, 30th, 70th and 85th percentile scores of SHMS V1.0.</p><p><b>CONCLUSION</b>We have established SHMS V1.0 norms for Chinese civil servants, which facilitates further investigation of the incidence of sub-health state and its contributing factors in civil servants.</p>
