Analysis of the acute postoperative pain experience following oral surgery: identification of 'unaffected', 'disabled' and 'depressed, anxious and disabled' patient clusters

Pain in Oral and Maxillofacial Surgery and Implant Dentistry: Types and Management

Over the years, the pain has been defined numerous times in several ways. In oral and maxillofacial surgery, the occurrence of pain, especially postoperatively, is anticipated. Pain arises as a combination of various processes after tissue damage. Distinct pain experiences in oral surgery were depicted in several previous studies, adding knowledge to the field. The management of these encounters has been suggested over time, improving treatment approaches in the clinical setting. This review aims to understand the pain and its types and intervention in the field of oral and maxillofacial surgery.

State anxiety and depression as factors modulating and influencing postoperative pain in dental implant surgery. A prospective clinical survey

Objetives: To determine whether preoperative state anxiety and depression modulate or influence objective and subjective postoperative pain following dental implant insertion. Study Design: Prospective, clinical study with 7-day follow-up of a sample of 105 subjects who preoperatively completed the state anxiety questionnaire (STAI-E) and Beck Depression Inventory (BDI) and postoperatively, at 2 and 7 days, recorded objective pain with the Semmes-Weinstein mechanical esthesiometer (SW test) and subjective pain with the Visual Analog Scale (VAS). Results: 85.6% and 81.5% of patients, respectively, recorded no signs of state anxiety or depression. The correlation between anxiety and depression for both maxillary bones was the lower (P=0.02). The correlation between subjective and objective pain at 2 and 7 days, and the anatomic regions intervened, was statistically significant in the mandible at day 7 (P<0.01), and highly significant (P<0.001) for the other variables. The correlation between state anxiety and objective pain at day 7 was nearly statistically significant (P=0.07). Conclusions: The correlation between state anxiety and depression, and objective and subjective pain at day 7 was not statistically significant. A strong correlation was found between objective and subjective pain in the immediate postoperative period.

Key words:Anxiety, depression, postoperative pain, dental implants.

Prototype of a tool for analysing laryngeal cancer operations

In this study, a software tool was developed to analyse the medical data collected from laryngeal cancer operations by using two data mining techniques. The software, run on real-world medical data, is a tool that enables medical decisions to be reached by analysing past records from patients. The k-means algorithm, which is a clustering algorithm in data mining, was used to point out the intensities in the data set and to display two dimensions on the charts. The data of three screens that were named as selective clustering, different pre- and post-operation stages and clustering operations based on pre-operation T values, were processed using clustering with the k-means algorithm and one screen, which named relapse and survival percentages, was processed through classifying. It helps the future decision-making process by considering false estimates of pre-operation stages of the cases and by using the information gathered from past cases concerning tumour relapse and the survival percentage for prognostication. The characteristics of laryngeal cancer operations data, that involve causal links, were exposed by using two data mining techniques in this application.
