ABSTRACT
Dermoid cysts are the least commonly occurring developmental cysts in the oral and maxillofacial region. They may be congenital or acquired and are seen as asymptomatic swellings that are slow and progressive. It is very difficult to differentiate plunging ranulas from plunging dermoid cysts as both of them have very similar clinical features. However, since both entities have different treatment strategies, it is important to differentiate one from the other. A 57-year-old male patient reported to the Department of Oral Medicine and Radiology with a large swelling in the submental region. To the best of our knowledge, the present case report is the first one showing such an extensive lesion of plunging dermoid cyst mimicking plunging ranula in an elderly male patient. The report mainly focuses on the diagnostic challenges faced to reach the final diagnosis.
ABSTRACT
Background: The masticatory muscles may undergo fatigue due to prolonged mouth opening during the endodontic procedures. Low-level laser can be used to treat muscle fatigue due its capacity to produce reactive oxygen species and improve function of mitochondria. Aim: To determine the effectiveness of low-level laser therapy in the management of masticatory muscle fatigue caused after long endodontic procedure under Local anesthesia. Material and Methods: 44 patients complaining of reduced mouth opening and pain while mouth opening, after long endodontic therapy were considered for the study and were randomly allocated into study and control group. In the study group, low-level laser was applied while patients of control group didn't receive any therapy. In the study group, Visual analogue scale (VAS) score of pain was taken after endodontic therapy, immediately after laser therapy and 4 hours after endodontic therapy. Mouth opening of the patients was measured, before and after endodontic procedure and immediately after laser therapy. In the control group, VAS score of pain was recorded immediately after endodontic therapy and 4 hours after endodontic therapy. Statistical analysis used: ANOVA test and un-paired t-test was used for the data analysis. Results: When both groups were compared, a statistically significant (P=0.0000) reduction with fatigue was found. Conclusions: The low-level laser can be a useful procedure immediately post long endodontic procedure causing masticatory muscle fatigue. Hence, this therapy can be considered as an add-on therapeutic procedure along with prolonged endodontic appointments to relieve the patient from the discomfort. Key words:Muscle fatigue, Masticatory muscles, Low-level laser therapy.
ABSTRACT
Mucocele is a common salivary gland lesion which most commonly occurs on the lower lip. Several treatment options are available for its elimination with surgery being the most commonly used method. A 49-year-old male presented with a small, round, painless swelling on the left buccal mucosa since 6 months. A clinical diagnosis of oral mucocele on the left buccal mucosa was made. Due to the inaccessibility of the posterior buccal mucosa region, sclerotherapy with sodium tetradecyl sulfate was planned. The patient did not show any obvious reduction in the size of swelling after 1 week of therapy. Therefore, a second injection was planned. After another 1 week, complete resolution of the lesion was seen with no complications. No recurrence of the lesion has been seen after 6 months of therapy. Due to the various drawbacks of surgical management of oral mucocele, sclerotherapy can be an effective alternative.
ABSTRACT
Azadirachta indica leaves are converted to a fine powder for use as a biosorbent for the removal of metal ions in aqueous solution. In this work, the adsorptive interactions between Ni(II) and the powder were studied under a variety of conditions involving variations in pH, Ni(II) concentration, biosorbent amount, interaction time and temperature, all in single batch processes. The experimental data have been interpreted on the basis of existing mathematical models of equilibrium kinetics and thermodynamics. The biosorption of Ni(II) increased in the pH range of 2.0-5.0 with approximately 92.6% adsorption at pH 5.0 for the highest amount of the biosorbent (4 g/L). The biosorption followed second-order kinetics and intra-particle diffusion was likely to have significant influence in controlling the process. The Langmuir monolayer adsorption capacity varied from 2.4 to 9.1mg/g and the equilibrium coefficient from 1.09 to 2.78 L/g with strong indication that the Ni(II) ions were held on the biosorbent surface by formation of an adsorption complex. The thermodynamic parameters showed the process to be exothermic in nature supported by appropriate ranges of values of enthalpy change, entropy change and Gibbs energy change.
