Although with only dental extraction as the procedure of choice, the present study has favoured the frontozygomatic angle approach for the maxillary nerve block as simple, safe, efficacious and associated with minimum and clinically mild complications.
Introduction:Intraepithelial dysplasia, or “invisible” precancerous lesions, provides a challenge for visualization to the surgical team. The prognostic relevance of dysplasia and carcinoma in situ at surgical margins is well documented.Materials and Methods:We evaluated the use of Lugol's iodine in visualizing the surgical margins of dysplastic tissue by an observational study of 100 patients having oral precancerous lesions between June 2013 and March 2016.Conclusion:Lugol's iodine is a simple, inexpensive, and apparently effective means of diagnosing and visualizing the surgical margins of the dysplastic tissue in oral precancerous lesions.
This article aims to discuss how Artificial Intelligence (AI) with its powerful pattern finding and prediction algorithms are helping orthodontics. Much remains to be done to help patients and clinicians make better treatment decisions. AI is an excellent tool to help orthodontists to choose the best way to move teeth with aligners to pre-set positions. On the other hand, AI today completely ignores the existence of oral diseases, does not fully integrate facial analysis in its algorithms, and is unable to consider the impact of functional problems in treatments. AI do increase sensitivity and specificity in imaging diagnosis in several conditions, from syndrome diagnosis to caries detection. AI with its set of tools for problem-solving is starting to assist orthodontists with extra powerful applied resources to provide better standards of care.
Correction of maxillary transverse discrepancy requires expansion of palate by combination of orthopedic and orthodontic movements. Isolated maxillary transverse deficiency can be treated either orthodontically or surgically with assisted rapid maxillary expansion (RME). Nonsurgical expansion modalities include rapid maxillary expansion and slow maxillary expansion. Haas popularized the idea of orthodontic palatal expansion in the 1960s, and since then transverse deficiencies have been treated successfully in children and adolescents. The use of palatal expanders in adults was widely frowned upon and was generally considered to be unsuccessful. Handelman published a clinical review in 1997, proving a nonsurgical expansion in adults was possible.
Purpose: Postoperative delirium (PD) is a common and severe complication, following extensive surgery and prolonged stays in intensive care units (ICU). The study aimed to estimate the frequency of and identify risk factors for PD in a unified orthognathic surgery patients. Methods: A retrospective cohort study composing of patients undergoing Maxillary and Mandibular orthognathic surgeries over 2 year. The predictor variables were identified as 146 general and periprocedural parameters. The primary outcome variable was PD (+ or -). Descriptive and bivariate statistics were performed to identify existing correlations between the predictive factors and PD and the P-value was set at 0.05. A logistic regression model (LRM) was created to adjust for possible confounding factors and reveal possible independent prognostic factors for the onset of PD. Results: 200 patients (36 with PD+, 164 without PD in patient history) undergoing Orthognathic Surgery [130 males, 70 females, mean age = 20 (range 18-40 years)] surgery were recruited. 15 variables that were statistically associated with PD were identified. In the LRM, after adjusting for age, diabetes status and preoperative TSH, Orthognathic surgery was associated with an risk for PD (Odds Ratio (OR) 6.3 (1.6-25.7, p=0.01).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
