Casual glycemia was practiced to 162 patients, who regularly attend public health services, and results from fasting blood glucose test were analyzed. A buccal examination and World Health Organization's community periodontal index and treatment needs (CPITN) was practiced. Descriptive statistics and bivaried analysis were used. the woman:man relation was 3:1, age range from 17 to 80 years. Out of 99 patients with laboratory glycemia, 76 % was poorly controlled; 99 % showed at least one buccal lesion: 93.2 %, periodontal disease; 73.4 %, xerostomia and 28.4 %, erythematous candidiasis. Having bad controlled glucose, a group with xerostomia and erythematous candidiasis and another showed xerostomia plus erythematous candidiasis plus periodontal disease (OR = 3.5 and a value of p = 0.01). presence of oral diseases is exhib...

Correlation between knowledge on dental ergonomics postures, positions of work and postural pain ... more Correlation between knowledge on dental ergonomics postures, positions of work and postural pain according to response of anatomic zones during clinical practices of dental students. ABSTRACT The objective of this study was to determine the correlation between the level of knowledge to different kinds of dental ergonomics postures, work postures and postural pain according to response of anatomic areas during clinical practices of fifth-year students from the School of Dentistry of Peruvian University Cayetano Heredia. The instruments used for this study were: a questionary that evaluated the knowledge on ergonomic working postures, a posture verification list that showed the student´s clinical working postures supported by digital photographs analyzed by the Autocad and Corel Draw computer programs. Visual Analogical Scale was used for perception and intensity of postural pain related to anatomic response areas. The Spearman's Rank Correlation Coefficient was used for the statistical analysis. Correct posture was observed in only 22.3% of the sample. The level of knowledge about dental ergonomic was (37.5%). The perception of postural pain was higher in the cervical area (75%), and lower in forearms (15%). Correlation was found between the level of knowledge about ergonomic dental postures and the application of dental work postures. It is concluded that there is a direct relation between the variables studied.
