Objective: This cross-sectional survey aimed to assess the knowledge of dentists and dental assistants practicing in Saudi Arabia regarding diabetes mellitus (DM) and periodontal diseases. Subjects and Methods: We used a pretested, closed-ended, multiple-choice questionnaire covering 2 principal sections: the assessment of previous educational training and practice, and the knowledge and scientific background regarding DM and periodontal diseases. The responses were grouped using the Likert-type scale. Results: The questionnaire showed a high reliability value of 0.805 as determined by a Cronbach’s α. Out of 365 subjects who were initially interviewed, 239 subjects participated (response rate 65.5%): general dentists (45.6%) and dental hygienists and assistants (54.4%). Of the participating dentists, 70.4% were males; in contrast, 87.7% of dental assistants were female. Eighty-five percent of the participants strongly agreed that evidence supports the association between periodontal diseases and DM. Remarkably, dental assistants (78%) agreed more than dentists (68.5%) that diabetic patients with periodontal conditions would have worse glycemic control compared to diabetic patients with no periodontal diseases. Seventy-five percent of the respondents were confident about performing oral health screening for diabetic patients. Significantly more dental assistants showed their desire to expand their practice to include oral health screening (85%) and education compared to dentists (74%). Conclusions: Both dentists and dental assistants in Saudi Arabia revealed a satisfactory knowledge level regarding the periodontal disease-diabetes interactions with no significant difference between the two groups. Further studies are recommended to assess the attitude of dental care providers while dealing with diabetic patients.

Background:Oral lichen planus and mouth dryness are common pathoses, yet not entirely understood. These two conditions may be associated, with a few studies investigating the relationship between mouth dryness and oral lichen planus providing conflicting results. None of the studies have explored the specific impact of disease treatment on mouth dryness.Objective:The purpose of this observational before and after comparison study was to examine the effect of treatment of oral lichen planus with topical corticosteroids on mouth dryness.Methods:Nineteen subjects with oral lichen planus were evaluated for the severity of xerostomia using a xerostomia inventory and a visual analogue scale. Stimulated and unstimulated whole salivary flow rates, unstimulated salivary pH and buffering capacity were also measured. All subjects were evaluated before and after treatment with topical corticosteroids.Results:All subjects reported xerostomia before treatment with topical corticosteroids, with 79% reporting a significant improvement (P = 0.03) after treatment. Topical corticosteroid treatment was not associated with statistically significant differences in stimulated or unstimulated salivary flow rates, unstimulated salivary pH or buffering capacity.Conclusion:The results of this study suggest that treatment of oral lichen planus with topical corticosteroids may decrease the severity of dry mouth symptoms.
