Lichen planus is a chronic mucocutaneous inflammatory disorder that is estimated to affect 0.5%-2.2% of the general population. 1 The cause is unknown in most cases; however, in a minority of patients, precipitating factors have been suggested, including dental materials, drugs, stress, and infectious agents. 2 It primarily affects middleaged adults, and the prevalence is greater among women. There are four forms of oral lichen planus (OLP) that relate to clinical appearance: reticular, atrophic, bullous, and erosive. 3 Symptoms arising from OLP vary markedly and often relate to the specific category.Patients with an atrophic/erosive form of OLP often present with symptoms ranging from burning sensation to severe pain, interfering with speaking, eating, and swallowing. 4Patients with symptomatic OLP often require therapy and should be treated if symptoms are significant. 5 Various treatments have Abstract Aim: Oral lichen planus (OLP) is a chronic mucocutaneous disorder seen in clinical dental practice. Despite the progress in research and advances in knowledge, the successful management of OLP is still difficult to achieve. The aim of the present study was to compare the therapeutic effects of triamcinolone (TA) preparation (0.1%) with hyaluronic acid (HA) preparation (0.2%) in the management of OLP. Methods:In total, 40 patients of any age or sex who had symptomatic OLP were selected and randomly divided into two groups. Group I received topical 0.1% TA, and group II received topical 0.2% HA preparation three times per day for a period of 4 weeks. Basement data were recorded for each patient. Patients were evaluated on days 14 and 21, and after completing the course of treatment. The visual analog scale (VAS) was used for evaluating pain and burning sensation, along with an evaluation of the degree of erythema and mean area of the lesion. Data were analyzed by SPSS 17.0 software using Mann-Whitney and t test. P ≤ 0.05 was considered statistically significant. Results:Our results showed considerable improvement in all of the parameters evaluated. Baseline characteristics, including pain score, size, and clinical characteristics of the lesions, were not different between the two treatment groups. Both TA and HA were found to reduce the VAS score, the degree of erythema, and size of the lesions after treatment. Conclusion:The application of HA is suggested, and is an effective substitute for TA in the treatment of OLP. K E Y W O R D Scorticosteroid, hyaluronic acid, mucocutaneous, oral lichen planus, triamcinolonePatients were asked to return to the clinic for review at 14, 21, and 28 days' post-baseline. During these visits, any changes in the VAS values and site of lesion, color, size, or appearance of the lesions were duly noted on the proforma. The entire data were then entered into the proforma. | Statistical analysisAll data were tabulated and analyzed using SPSS version 17.0 (Chicago, IL, USA).

Objective: The aim of this study was to assess apical root resorption (RR) following the application of micro-osteoperforation (MOP) and piezocision (PzC) assisted orthodontics for the acceleration of tooth movement (TM). Materials and Methods: A total number of 16 patients seeking orthodontic therapy were included in this study. All patients had undergone 1 st premolars extraction and were indicated for canine retraction. These patients were divided into two groups; one was treated using MOP in one side while the other side served as control. In the other group PzC was performed in one side with no intervention done on the other side. Cone-beam Computed Tomography (CBCT) scans were obtained for every patient before and after canine retraction in order to evaluate amount of RR. Results: In the MOP group, there was no significant difference in canine root length between experimental and control sides. Whereas, in the PzC group, there was a statistically significant decrease in root length in the experimental side compared with the control side. When comparing both groups, the experimental PzC side showed a statistically significant decrease in root length compared to experimental MOP side postoperatively. Conclusion: Experimental PzC showed statistically significant decreases in canine root length compared to both experimental MOP and control side after canine retraction.

Background: Due to limited data about the prevalence of the moderate chronic periodontitis among smokers and non- smokers in Saudi population this study was conducted.Methods: For each participant, full mouth periodontal examination was performed and recorded on a special examination form by one of the 3 examiners. These data included probing depth (PD), clinical attachment level (CAL). The Data was collected and entered into the personal computer. Statistical analysis was done using Statistical Package for Social Sciences (SPSS/version 21) software. Number and percent of each category were calculated, for categorized parameters, chi square test was used. The level of significant was 0.05.Results: On comparison the prevalence of moderate chronic periodontitis among the smoker and non- smoker groups, chi square test was 9.114, with ( p< 0.05) which is statistically significant, while on comparison the age between the two groups, it was found that there was no significant relation between the age and the different grade of chronic periodontitis.Conclusion: Moderate Chronic Periodontitis is more prevalent among smokers in Aljouf province, Kingdom of Saudi Arabia.International Journal of Human and Health Sciences Vol. 02 No. 03 July’18.
