Molecular docking technique was done to study these compounds and their interactions with the target protein in the test organism.

This has been proven successful in bone preservation for future implant insertion or prosthetic treatment. Several materials of bone allograft, xenografts, synthetics and membranes were successful in socket preservation however the healing duration and the outcome of bone formed differs. Ten patients selected with posterior extraction sockets for the augmentation procedure, the bone graft mass mixed with Amnio-Spark fluid (Salvin Dental Specialties, Charlotte, NC, USA) and the wound secured with sutures and left to heal with no covering membrane.

Core bone biopsies taken at twelve weeks demonstrated a pattern of viable bone formation with minor remnants of the bone graft material.

On considering the impact of such post-operative sequelae on the patient’s quality of life, it is necessary to exercise preventive measures to minimize the occurrence of such complications / untoward events. Although many retractors are already in application for retraction of tissues during the third molar extraction, this manuscript describes an innovative multifunctional concept “Nyer Zet-ractor” designed for retraction and isolation without limiting the accessibility to the surgical area in mandibular third molar surgery.\u0000\u0000The “Nyer Zet-ractor” described in this manuscript is an innovative device which provides the advantages like clear access, continuous visibility and excellent isolation of the surgical site unlike conventional retractors with minimal retractive forces thereby reducing post-operative pain and swelling. Nyer Zet-ractor implements a multifunctional concept of retraction making it an efficient, easy to use, and exerts a known and finite amount of force, thereby avoiding tissue damage.","PeriodicalId":92922,"journal":{"name":"Journal of dentistry and oral sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41600999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We therefore accessed the pattern and indications of tooth loss in the patients who presented at oral surgery clinic for intra-alveolar tooth extraction over a twelve month period.\u0000Methods: This is a prospective cohort study of adult patients tooth extraction between September 2015 and August 2016. Patients’ demographic and clinical data were collected with a structured questionnaire. Data were analyzed using statistical package for social sciences (SPSS) version 23.0. Variables were subjected to Pearson’s chi-square test and P <0.05 was considered statistically significant. \u0000Results: A total of 240 adults age range between 18 to 75 years of age with mean age of 36.64 years were included in the analysis. Maxillary teeth (231) and mandibular teeth (326) were extracted in 203 and 263 patients respectively. Caries and its sequelae, 223(93%) were the predominant indication for tooth extractions. Lower second molar (25%), and upper third molar (20%) had the highest frequencies. More female (126, 52.5%) than male (114, 47.5%) had extraction done, the difference is however not statistically significant (X2 =1.67, P Value = 0.195) \u0000Conclusions: Dental caries and its sequelae are the most frequent cause of tooth extraction. Tooth extraction was more in Patients in the fourth decade as well as in the Female gender, even though the difference between male and female is not statistically significant. And there is increased in number of male who had extraction done compared to what obtained in the past decades. Left side of the mouth appeared to be more affected.","PeriodicalId":92922,"journal":{"name":"Journal of dentistry and oral sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48768690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral functions and facial aesthetics are influenced by the severity of malocclusion and it's of great concern to the individual, their families and health authorities as well. Most of the reported studies for Kingdom of Saudi Arabia are from the eastern, southern and central region. To the best of our knowledge no data is available for the northern region of Hail; therefore the aim of this study was to determine the prevalence of malocclusion among the population of Hail city.\u0000\u0000Methodology: Descriptive study having a cross sectional study, convenient sample size of 504 Saudi populations between the age group of 13 – 50 years. Informed consent was taken from the participants before conducting the examination, parents’ consent was sought for children. Malocclusion was recorded as described by WHO, oral health Survey, and basic methods. Each subject was examined for the type of malocclusion according to Angle’s classification.\u0000\u0000Results: Most predominant malocclusion was Angle’s Class I 41.7% in females and 26.2% in males.15.4% males and 23.3% females had excessive overjet (>2mm) compared to 38% males and (24.3%) females who had reduced overjet (2mm) whereas 32.3% males and 20.5% females had reduced overbite (<1 mm), anterior cross bite was reported in 5.6%males and (1.3%) females and open bite in 5.6% males and 5.5 % females.\u0000\u0000Conclusion: Within the limitations of this study, the prevalence of malocclusion in Hail region of Saudi Arabia is comparable with that of other regional studies.Most of the study participants exhibited Angles class I occlusal features with normal overjet and overbite.","PeriodicalId":92922,"journal":{"name":"Journal of dentistry and oral sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46368678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
