RESUMO
BACKGROUND: Psychiatric diseases like anxiety, depression, schizophrenia and bipolar disorders can affect the mental and physical statuses of an individual. AIM: The study was to investigate the different oromucosal diseases (OMD) in psychiatric patients and to evaluate the correlation between these OMD to severity of anxiety and depression. MATERIALS AND METHODS: A cross-sectional study was carried out during a six-month period. Patients reporting to psychiatry department with anxiety, depression, schizophrenia and bipolar disorder as diagnosed by an experienced psychiatrist, were subjected to complete oral examination by a skilled oral diagnostician to check for OMD like oral lichen planus (OLP), aphthous stomatitis (AS) and burning mouth syndrome (BMS). During the above mentioned time interval, 1320 patients with any of the above mentioned psychiatric diseases were included in this study. Of these, 278 had anxiety, 398 had depression, 295 had schizophrenia and 349 had bipolar disorder. Equal number of individuals reported to the Oral Medicine and Radiology department for routine oral screening with no mucosal diseases were included as control group. RESULTS: In this study, statistically significant increase in the OMD of the psychiatric patients was recorded when compared with the control group. The OMD were significantly higher in patients with anxiety (20.86%) followed by patients with depression (9.04%), schizophrenia (7.7%), bipolar disorder (7.4%) and control group (5.17%), respectively. Most prevalent OMD in patients with anxiety was AS (12%) followed by OLP (5.7%), and BMS (2.87%) respectively. Patients with moderate to severe anxiety and depression showed significantly higher prevalence of these OMD compared to the ones with mild anxiety and depression. The AS and OLP were significantly more in the younger age group (18-49 year) and BMS was higher in 50-77 year age group in both the study and control groups. CONCLUSION: A positive association was established between psychological alterations and OMD. Emotional alterations may act as a precipitating factor that could influence the initiation and development of different OMD. Hence, better harmonization is essential between dentist and psychiatrists for comprehensive management of psychosomatic disorders of the oral mucosa.
RESUMO
BACKGROUND: Curve of Spee was first described by Ferdin and Graf Von Spee in 1890. The curve of Spee is an important characteristic of the mandibular dental arch. One of the most frequently encountered problems in the treatment of orthodontic patients is an excessive overbite. Deep bite has been found to be associated with abnormal mandibular function. Temporomandibular joint disorders also have potentially detrimental effects on mandibular development. Andrews advocated leveling the curve of Spee to aflat curve, in order to facilitate construction of an optimal occlusion and that a flat plane should be given as a form of over treatment. There is no reliable information currently available from the literature about the long-term stability of the curve of Spee and the factors influencing the same. The objective of this study was to assess the post-retention development of the curve of Spee and to evaluate the dental and skeletal parameters as predictors of its post-retention stability. MATERIALS AND METHODS: Pre-treatment (Tl), post-treatment (T2) and post-retention (T3) dental casts and lateral cephalograms of 24 orthodontically treated patients having a mean age of 14.5 years were evaluated. The mean period of the study group after retention was up to 2.6 years (range = 1-5 years). Pre-treatment T1, post-treatment T2, and post-retention T3 casts and radiographs were measured. The data were tabulated and statistically analyzed. RESULTS: A highly significant positive correlation was observed between the changes in the curve of Spee during treatment (T2-T1) and the net result after retention (T3-T2). This means that much of the treatment results remained stable at T3. However, slight change was noticed in curve of Spee's depth during the time interval T3-T2. This finding was very negligible and was not statistically significant. CONCLUSION: The leveling of the curve of Spee during the treatment is a stable treatment objective on long term basis. There was a mild correlation existing between the curve of Spee and the different dental and skeletal parameters.
