Importance of cephalographs in diagnosis of patients with sleep apnea.

INTRODUCTION: Obstructive sleep apnea (OSA) is considered to be a potentially life threatening disorder, which is characterized by repeated collapse of the upper airway during sleep with cessation of breathing. The cephalometric method despite being a static, two-dimensional evaluation of dynamic three-dimensional structures of the head and neck is useful in diagnosing patients with OSA, as they have shown that significant differences exist between asymptomatic controls and patients with OSA. AIMS AND OBJECTIVES: This study is designed to compare and validate the craniofacial morphology in patients with OSA using lateral cephalometry in both upright and supine position. MATERIALS AND METHODS: Sixty subjects participated in the study of which 30 were patients with OSA diagnosed by questionnaire and 30 were healthy control group with age range of 25-45 years. RESULTS: The study group demonstrated an increased ANB, mandibular plane angles (GoGn-SN), lower anterior facial height which are statistically significant with a significant P < 0.05. Significant decrease in posterior airway space, increased soft palate length, tongue length, and thickness suggesting reduced airway space in supine posture. CONCLUSION: Evaluation of craniofacial morphology in OSA patients using lateral cephalometry helps in recognizing the morphological changes induced by altered sleep pattern and for appropriate treatment planning.

Randomized trial of aloe vera gel vs triamcinolone acetonide ointment in the treatment of oral lichen planus.

OBJECTIVE: To determine the effectiveness of aloe vera gel in the treatment of oral lichen planus when compared with triamcinolone acetonide. METHOD AND MATERIALS: A randomized, double-blind, clinical trial was designed. The study sample constituted 40 patients (23 males and 17 females) who were randomly divided into two equal groups. Group A patients received aloe vera gel, while group B patients received triamcinolone acetonide. RESULTS: Forty patients were included in the study. Most of the sample presented with erosive (n = 18) and atrophic (n = 14) variants of oral lichen planus. When clinical signs and symptoms were observed after 8 weeks of therapy, it was determined that aloe vera gel was more effective than triamcinolone acetonide in the treatment of oral lichen planus. CONCLUSION: Aloe vera gel can be considered a safe alternative treatment for oral lichen planus.
