Evaluation of oral mechanical and gustatory sensitivities and salivary cotinine levels in adult smokers.

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.

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

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).
