Abstract Background The most severe complication after the removal of mandibular third molars is injury to inferior alveolar nerve or lingual nerve. These complications are rather uncommon (0.4% 8.4%) and them transient. However, some persist for longer than 6 months, which can leave various degrees long-term permanent disability. While several methods such as pharmacologic therapy, microneurosurgery, autogenous alloplastic grafting be used treatment long-standing sensory aberrations in...

The inferior alveolar nerve is the one of large branches mandibular division trigeminal nerve. It vulnerable during surgical procedures mandible. Despite its importance, no anatomical and histological examination has been conducted to provide a detailed cross-sectional morphology canal according dental status. Therefore, present study aimed identify position through direct measurement determine histologic examination. area between anterior margin third molar second premolar dentulous,...

Background: The aim of periodontal therapy is to prevent tissue destruction while achieving the regeneration damaged tissues. Platelet‐rich plasma (PRP) used generate new bone, ligament, and attachment with a strategy based on modulation enhancement wound healing through an autologous source for growth factors obtained from patient's own blood. purpose present study was evaluate efficacy PRP when in combination β‐tricalcium phosphate (β‐TCP) alloplastic graft material collagen barrier...

The aims of this study were to evaluate bone-to-implant contact (BIC) and the osteoconductive capacity bioactive fiber-reinforced composite implant (FRC) in vivo.Threaded sand-blasted FRC implants threaded with glass (BAG) fabricated for study. Titanium used as a reference. Eighteen (diameter 4.1 mm, length 10 mm) implanted tibia six pigs using press-fit technique. animals sacrificed after 4 12 weeks. Histomorphometric scanning electron microscopic (SEM) analyses performed characterize...

The anatomical structure of the maxillary sinus is fundamental to maxillofacial surgery. presence septa, located at inner surface sinus, increases risk membrane perforation during elevation for dental implant aim this study was evaluate anatomy septa.Data in obtained from a total 205 cases. One hundred and seventy-seven patients were partially edentulous (PE) whereas 28 had no teeth. Dental computerized tomography (dental CT) used assessment 410 segments (205 left right segments). prevalence...

Purpose: This study was performed to compare the accuracy of micro-computed tomography (CT) and cone-beam computed (CBCT) in detecting accessory canals primary molars.Materials Methods: Forty-one extracted human first second molars were embedded wax blocks scanned using micro-CT CBCT.After images taken, samples processed a clearing technique examined under stereomicroscope order establish gold standard for this study.The specimens classified into three groups: maxillary molars, mandibular...

Background: Gingival hyperplasia (GH) is a major side effect associated with cyclosporin A (CsA) therapy. The condition further augmented due to the gingival inflammation. In this study, effects of initial periodontal therapy and curettage are analyzed in group patients clinically significant (>30%) CsAinduced hyperplasia. Methods: test 15 received oral hygiene instructions, supra‐ subgingival scaling, polishing, only instructions were given 16 control subjects. Plaque index (PI), (GI),...

The aim was to assess the accuracy and reproducibility of measurements chemically created periapical lesions using limited cone beam CT.Periapical were in 18 mandibular cadaver teeth. Mandibles dissected buccolingually a bone-cutting burr. Diameters depths measured directly cross-sectional slices precision digital caliper. then embedded wax, CT images acquired NewTom 3G Plus scanner with both 6 inch 9 fields view (FOVs). Two oral radiologists diameter depth on built-in measurement tools....

Clinical Relevance The three tested desensitizing agents were equally effective in relieving dentin hypersensitivity and showed statistically significant pain reduction when compared to a placebo.

Oral findings in patients with ectodermal dysplasia (ED) include complete or partial hypodontia, anodontia, loss of vertical dimension occlusion, protuberant lips, malformed and widely spaced conical-shaped teeth, underdeveloped alveolar ridges. These present a substantial challenge dental treatment. This case report presents oral rehabilitation 22-year-old male patient diagnosed ED using an implant tooth-supported telescopic denture at the mandible maxilla. Implants were placed sites right...

Abstract HLA‐A, B, C and DR antigen frequencies were determined in a group of patients with juvenile periodontitis rapidly progressive periodontitis. In patients. HLA‐A24 DR4 found at significantly higher level than the control group, patients, A9 group. The presence these antigens gives evidence as to susceptibility various forms early onset

This study has been designed to investigate the immunogenetic susceptibility of Cyclosporine-A (CsA) immunosuppressed renal transplant patients development gingival overgrowth, and amplifying effect calcium channel blockers on severity this clinical entity. 52 recipients were selected initially grouped as follows: group (Gp)1: CsA (n = 7); Gp 2: + verapamil 26); 3: diltiazem 6); 4: nifedipine 13). These groups not found be significantly different in age, sex, plaque index (PlI), (GI),...
