ABSTRACT
Background. Obesity Is A Worldwide Medical Problem, Which Is An Abnormal Or Extensive Fat Accumulation. Nowadays, There Are Many Types Of Nonprescribed Dietary Supplements That Are Used For Weight Loss As Green Coffee Bean Extract And Agiolax. As A Result Of Their Effect On Fluid Excretion, Both Of These Products May Be Expected To Have A Damaging Effect On Parotid Salivary Gland. Objectives. The Present Work Aims To Compare Between The Effect Of Using Green Coffee Bean Extract And Agiolax On The Integrity Of Parotid Salivary Glands Of Albino Rats. Material And Methods. Twenty-seven Adult Male Albino Rats Were Randomly Assigned To 3 Groups. Nine Received Distilled Water Daily For 2 Months By Oral Gavage (the Control Group); The Other 2 Groups Received 1 Mg/100 Gm.body Weight Green Coffee Bean Extract Or Agiolax 8 Mg/100 Gm.body Weight Daily For 2 Months By Oral Gavage (the GC And Ag Groups, Respectively). The Parotid Glands Were Dissected And Examined Histologically, Histomorphometrically, Biochemically, Immunohistochemically For Caspase-3 And By Real Time PCR. Results.The Immunoreaction Of Caspase-3 Was Significantly Increase In Agiolax Group And Green Coffe Bean Extract. Biochemically, The Value Of Calcium In Serum Was The Lowest In Agiolax Group. However, The Highest Mean Value Of Calcium In Urine Was Recorded In Agiolax Group As Compared To The Other Two Groups. In Addition, The Calcium Level In Tissue Was Decrease In Green Coffee Group And Agiolax. PCR For Calbindin-2 Recorded The Lowest Value In Green Coffee Bean Extract Group. Conclusions. Long-term Oral Administration Of Green Coffee Bean Extract And Agiolax Might Lead To Degenerative Changes In The Parotid Glands. A Greater Deleterious Effect Was Caused By Agiolax, As It Caused More Caspase-3 Expression, Significantly Reduced Ca Level In The Tissue And In Serum. In Addition, Calbindin-2 Recorded The Lowest Value In Green Coffee Bean Extract Group.

ABSTRACT


Purpose: To Evaluate The Stress Distribution In Mandibular Overdenture Retained By Two Splinted Mini Implants Using Monoplane And Lingualized Occlusion In Setting Of Teeth Using T-Scan.

Materials and Methods: Fourteen Patients Were Selected According To The Inclusion Criteria, The Participants Were Stratified Equally Into Two Groups, Patients Were Assigned To Receive Either Monoplane Or Lingualized Occlusal Schemes To Their Overdentures. For Each Patient Placement Of Two Mini-implants In The Mandible At The Canine Region Was Done, Bar Joint Attachment Was Used To Splint The Mini Implants. Each Implant Was 2.5 Mm In Diameter And 10 Mm In Length. T-scan Occlusal Load Analysis Records Were Done In Centric Occlusion, The Records Was Used To Analyze The Biting Force Of The Denture As A Full Closure Force Movie Recording, Then Time Vs. Force Graph Of That Force Movie Is Accomplished. T-scan Records Were Taken Three Times For Each Patient In The Two Groups, Immediately After Loading, Three Months And Six Months Of Loading.

Results: Within The Limitation Of This Study, The Results Revealed That The Effect Of Time On Load Distribution For Monoplane Ana Lingualized Groups Showed Increase In The Anterior Region Stresses But These Increases Were Statisticaly Insignificant, Also The Effect Of Different Occlusal Schemes On Load Distribution For Follow Up Periods Was Statistically Significant. The Results Also Revealed No Statistically Significant Difference Between Occlusal Forces Within The Same Group At Different Follow Up Period.

ABSTRACT


Aim: The Aim Of This Prospective, Randomized, Placebo-controlled Clinical Trial Was To Evaluate The Effect Of Pre-operative, Single-dose Clindamycin On Post-operative Pain In Patients With Symptomatic Apical Periodontitis Treated In One Visit. Methods: Seventy-two Participants Diagnosed With Symptomatic Apical Periodontitis In Their Mandibular Posterior Teeth Were Included. Patients Were Randomly Assigned Into Either Of Two Groups: Clindamycin Group, Where A Pre-operative, Single-dose Of Clindamycin (600 Mg) Or Placebo Group, Where Pre-operative Placebo Was Given (n=36). After 30 Minutes Of Receiving Medication, Root Canal Treatment Was Performed In A Single Visit. Patients Were Instructed To Rate Their Pain Felt After Endodontic Procedure In A Pain Diary At 6, 12, 24, 48, 72 Hours And At Day 7 Using A Numerical Rating Scale (NRS). Data Were Statistically Analyzed And The Significant Level (?) Was Set As 0.05.

Results: Both Groups Were Similar Regarding Baseline Characteristics, Including: Age, Gender, Canal-number Distribution, Tooth Type And Preoperative Pain (p>0.05). There Was No Statistically Significant Difference Between Both Groups In Post-operative Pain Intensity Or Incidence At Any Of The Follow-up Time Points (p>0.05). Conclusion: Pre-operative Administration Of A Single-dose Of 600 Mg Clindamycin Does Not Seem To Affect Post-operative Pain Intensity Or Incidence For Patients With Mandibular Posterior Teeth With Symptomatic Apical Periodontitis Treated In A Single Visit.
