Influence of lingual bracket position on microbial and periodontal parameters in vivo

OBJECTIVE: Lingual orthodontics is becoming more popular in dental practice. The purpose of the present investigation was to compare plaque formation on teeth bonded with the same bracket onto buccal or lingual surface, with non-bonded control teeth, via an in vivo growth experiment over a 30-day period. MATERIAL AND METHODS: A randomized controlled trial with split-mouth design was set up enrolling 20 dental students. Within each subject sites with buccal and lingual brackets and control sites were followed. Clinical periodontal parameters (periodontal pocket depth: PPD; bleeding on probing: BOP) were recorded at baseline and on days 1, 7 and 30. Microbiological samples were taken from the brackets and the teeth on days 1, 7 and 30 to detect colony-forming units (CFU). Total CFU, streptococci CFU and anaerobe CFU were measured. RESULTS: No significant differences (P>0.05) were found between buccal and lingual brackets in terms of clinical periodontal parameters and microbiological values. Conclusion: Bracket position does not have significant impact on bacterial load and on periodontal parameters

Epilepsy and Psychiatric Comorbidities: New Approaches and Perspectives

Psychiatry and neurology are specialties learned separately, but often the semiology and the pathophysiology of the different cases are linked. Patients often need an integrative approach in order to have an appropriate answer to their problems. In this chapter we will discuss the psychiatric comorbidities of epilepsy, such as depression, psychosis, stress, and anxiety disorders. Depression is the most common psychiatric comorbidity of epilepsy, significantly affecting the quality of life of patients. Anxiety disorders occupy a second place, often generating severe problems. They are usually underestimated at the clinical level, despite the abundant scientific evidence that supports the search and treatment of them in this group of patients. The problem of psychotic disorders in epilepsy is often controversial. There are few studies on this subject, and the psychopathological mechanisms behind them remain largely unknown. The problem of diagnoses and management of psychogenic nonepileptic seizures will also be briefly reviewed. They usually represent 20% of the patients referred to specialized centers of epilepsy, after having spent between 5 and 10 years through the health system. They are a frequent entity but often confused and mistreated, generating unnecessary expenses and waste of time. Finally, we will summarize how the management of stress and emotions in general has a direct impact on the quality of life of these patients.Fil: Gargiulo, Ángel José Martín.
