Résumé
Objective: To compare self-perceived oral symptoms and clinical [plaque index [PI], bleeding on probing [BOP], clinical attachment loss [CAL]] and radiographic [marginal bone loss [MBL]] periodontal parameters among naswar [NW] and non-naswar dippers [NNW]
Methods: One hundred and forty-two individuals [72 patients consuming naswar and 70 controls] were included. All participants completed a baseline questionnaire that included information regarding demographic characteristics and self-perceived oral symptoms. Clinical periodontal parameters [PI, BOP, PD and CAL] were recorded. MBL was measured on digital panoramic radiographs
Results: Pain in teeth, pain on chewing, bleeding gums and burning sensation in the mouth was significantly worse among NW than NNW [p<0.01]. Clinical periodontal parameters and MBL were significantly high in NW than NNW [p<0.001]. There was statistically significant influence of daily use and mean duration of naswar consumption on the severity of PI, BOP, PD [4 to 6 and >6 mm] and MBL among NW group
Conclusion: Self-perceived oral symptoms and periodontal parameters were worse among naswardippers. It is highly recommended that naswar dipping should be considered a potential threat that could have major effects on periodontal tissues
Résumé
Background: Oral cancer is regarded as the sixth most common malignant tumor and is one of the leading cause of death. Lymph node metastasis is a major factor for the prognosis of oral squamous cell carcinoma [OSCC]. The objective of study was to compare the lymph node metastases with different histopathological parameters to identify high risk patients with the need for extensive treatment plans
Methods: 140 histologically proven OSCC patients visiting Ziauddin College of Dentistry were included in this study. The clinico-pathological parameters were compared by using Chi-square, Kruskal-Willis and Mann-Whitney
Results: There were 90 male and 50 female patients with 29.8% in 49-58 years age group. Buccal mucosa was the most common site of tumor. The predominant morphology of OSCC was moderately differentiated OSCC with stage IV disease. Lymph node metastasis was present in 48.6% of patients. Perineural invasion [22.9%], lymphovascular invasion [8.6%] and distant metastasis [11.1%] were also recorded. The mean tumor size was 3.45mm +/-1.95mm and mean tumor thickness was 1.8 +/-1.6mm
Conclusion: A significant association between grade, stage, tumor size, tumor thickness and distant metastasis with lymph node involvement was found. However further studies with larger sample size are required to validate these results
