The purpose of this article is to review and understand currently used elastomeric impression materials in the fabrication of complete dentures. The article focuses on polyether (PE), polysulphide, vinylpolysiloxanes (VPS) (addition silicones) and condensation silicone (CS) by comparing their clinical implications and properties. The choice amongst different elastomeric impression materials depend on the combination of their characteristics, clinician's comprehension of the notions and principles in impression making.

Background: The prevalence of third molar pathology and problems associated with surgical extraction of impacted third molars has been extensively discussed in the literature; however, few have discussed the pathologies that can be associated with impacted third molar tooth. Aim: The aim of the current study, therefore, is to evaluate the types of associated pathologies with impacted third molars in Sub-Saharan Africans. Materials and Methods: This is a prospective study that was conducted in the Department of Oral and Maxillofacial Surgery, Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife, Osun State, Nigeria, between January and March 2012. Consented patients between ages 18 and 35 years were recruited into the study. Data were analyzed using IBM SPSS Statistics for Windows Version 20 (IBM Corp., Armonk, NY, USA). Statistical significance was set at P < 0.05. Results: A total of 135 mandibular third molar extractions was carried out during the study period from 72 (53.3%) females and 63 (46.7%) males (F:M = 1.1:1). Mesioangular impaction was the most frequent spatial relation of the impacted mandibular third molar to the lower second molar tooth (70 [51.9%]), followed by distoangular impaction (29 [21.5%]). Mesioangular impaction was mostly associated with pathology (70 [51.9%]), with a statistical significant difference of P = 0.000. Pathological pocket and caries on both impacted lower third molar and lower second molar tooth accounted for the highest number of associated pathologies (37 [27.4%]). Conclusion: Caries and pathological pockets were the most common associated pathology with impacted third molar.

The pyogenic granuloma (PG) is an exuberant tissue response to local irritation or trauma. The young lesions are highly vascular, red or reddish purple, often elevated and ulcerated, and bleed easily. Older lesions tend to be more collagenized and pink in appearance. Despite the name, no pyogenic material or pus is found in the lesion. Treatment protocol of PG includes many options. However, surgical excision is the treatment of choice. Several others highlighted the extremely varied recurrence rates. This case report aims to present 3-year follow-up management of mucogingival defect following surgical excision of PG.

Dentigerous cysts are benign odontogenic cysts occurring from the dental follicle of an unerupted or developing tooth. This cyst is usually asymptomatic but has the potential to attain a large size and become aggressive. These lesions are usually associated with the impacted third molars and canines. The treatment for this cyst is the extraction of the impacted tooth and enucleation of the cyst. A prosthodontist should be involved in the restoration of the lost structure from the point of diagnosis to establish proper function and improve the quality of life for the patient. We present a case report of a dentigerous cyst associated with an impacted mandibular molar which was surgically removed, and the defect was closed by an obturator fabricated before the surgical procedure.

Background and Objectives: Lack of scientific writing skills is believed to be a major obstacle in the course of research publication and dissemination by the Iranian researchers. Without following the globally accepted publication standards, dissertations, and projects cannot reach their final goal of being published and incorporated into practice. We aimed to compare the writing quality of a number of dental original articles written in Farsi and published in the Iranian journals with those written in English and published in international journals. Materials and Methods: In this analytical cross-sectional study, we selected 64 articles from six dental journals (three international English journals and three Farsi journals) by simple random sampling method. A list of 48 variables covering the study design, sampling method, subject allocation, ethical issues, interventions, measurements, and statistical methods was used to evaluate each article. The results were analyzed using Chi-square or Fisher's exact test. Results: Our results demonstrated that Farsi articles (n = 32) fulfilled 61.1% of our checklist criteria while English articles (n = 32) achieved a score of 59.1%, with no statistically significant difference (P > 0.05). Conclusion: We believe that the selected articles successfully reported most of the necessary elements. Their main shortcoming seemed to be the lack of clarification of details.
