The aim was to examine oral mechanical and gustatory sensitivities in adult smokers and to estimate salivary levels of cotinine by tobacco consumption. A total of 54 adults (20-45 years old; 28 males/26 females) were divided into two sex-paired groups: smoker group ( = 27), tobacco consumers with no other chronic disease/use of chronic medication, and a control non-smoker non-exposed group with similar age ( = 27). 24 h-Recall was used to gather information about tobacco consumption, date of onset and duration of the habit. Oral mechanical evaluation comprised touch detection threshold (MDT) of upper and lower lips and tongue tip and two-point discrimination (TPD) assessments. Taste sensitivities for sweet, salty, sour and bitter were evaluated in four concentrations. Salivary cotinine was determined by high performance liquid chromatography. Statistical analysis comprised Mann-Whitney, Two-way ANOVA test and regression analysis. The mean smoking time was 13.6 years (mean 8.4 mg/day; 13 cigarettes/day). A sex-effect was observed on MDT of tongue tip (higher sensitivity in females), while group-effect was observed on TPD of lower lip, showing a smaller sensitivity among smokers ( < .05; moderate effect: Eta partial = 0.076). Although the total score of gustatory sensitivity did not differ between groups, smokers exhibited an irregular pattern of correctly identified tastants among the different concentrations of salty, sour and bitter. The predictive model showed that salivary cotinine was dependent on "nicotine consumption on the day before" ( = 49%). A difference in tactile sensitivity of the lower lip and qualitative changes in taste sensitivity were observed in smokers.

Periodontal and dental effects of surgically assisted rapid maxillary expansion, assessed by using digital study models.

Dental Press J Orthod 2015 May-Jun;20(3):58-63

Universidade de São Paulo, São Bernardo do Campo, São Paulo, Brazil.

Objective: The present study assessed the maxillary dental arch changes produced by surgically assisted rapid maxillary expansion (SARME).

Methods: Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment onset (T1), three months after SARME (T2) and 6 months after expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape, Copenhagen, Denmark). Maxillary dental arch width, dental crown tipping and height were measured and assessed by ANOVA and Tukey's test.

Results: Increased transversal widths from T1 and T2 and the maintenance of these values from T2 and T3 were observed. Buccal teeth tipping also showed statistically significant differences, with an increase in all teeth from T1 to T2 and a decrease from T2 to T3. No statistically significant difference was found for dental crown height, except for left first and second molars, although clinically irrelevant.

Conclusion: SARME proved to be an effective and stable procedure, with minimum periodontal hazards.
