In order to make more successful prostheses, it is important to establish a relationship between patients’ complaints and clinical and radiological findings. The study was conducted with 90 patients between 2019-2020. The aim of this study was to compare the failure rates of the fixed prosthesis used by the patients according to the dental supported fixed prosthetic failure scale in terms of age, gender, clinical and radiological status, education level, duration of use, and prosthesis material. Methods: Failure classification in prosthetic restorations was made with Manappallil’s failure level scale seen in tooth-supported fixed prostheses. The SPSS v20 program was used to analyze the data. Categorical variables were presented as numbers and percentages while numerical variables were presented as mean and standard deviation. Relationships between numerical variables, student T test, Kruskal Wallis and Spearman correlation tests, and relationships between categorical variables were determined by a chi-square test. p <0.05 was considered statistically significant. Results: between moderate positive correlation between age and failure classes (p<0.001, r=0.39). It was observed that there was a significant relationship between duration of prosthesis use and failure classes (p<0.05). There was a low degree of positive correlation between age and duration of use (p<0.05, r=0.23). There was no relationship between the clinical condition and radiological findings of the patient and the education level and failure classification.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128129874","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}

There could be multifactorial etiology with various factors such as maldevelopment of the brain, perinatal stroke, prenatal infection, genetic disorder, ischemic insult in utero or prematurity, thrombophilic disorders, teratogenic exposures, multiple gestations ,maternal fever, exposure to toxins, abdominal trauma, malformation of brain structures, abnormal fetal presentation, instrument delivery, hyperbilirubinemia, meningitis, chronic lung disease, shaken baby syndrome as the possible causes. The children inflicted with CP are at a higher risk for developing oral manifestations such as Early Childhood Caries (ECC) due to poor oral hygiene, intake of soft diet, difficulty in chewing and swallowing and increased use of sugary oral medications. Behavioural challenges due to associated mental retardation demands pharmacological management under General Anaesthesia (GA) and we present a case series of successful management of Severe ECC in five children diagnosed with CP managed with full mouth rehabilitation under GA.

Periodontitis is the most devastating outcome of poor oral hygiene [7]. In several epidemiological studies, periodontitis reported to be associated with increased risk of OSCC [8-12]. Periodontitis is an inflammatory disease of the periodontium with polymicrobial aetiology [13].

Promising evidence has been obtained, thus inhibition of apoptosis, activation of uncontrolled cell proliferation, promotion of cell migration/ invasion as well production of carcinogenic virulence factors reported to be responsible for oral carcinogenesis [3].

Any conservative treatment that can delay or eliminate future prosthodontic problems should be considered. Complete and partially edentulous patients are generally unsatisfied due to the inherent instability of dentures during functional and parafunctional movements which results due to the lack of adequate supporting hard and soft tissues. Inspite of rapid development and good success rate in the field of implantology, preservation of remaining natural teeth or roots is more desirable which supports Devan’s dictum. Overdenture is a complete or partial denture prosthesis supported partly by soft tissues and partly by retained natural teeth or its roots or implants. Overdenture increases the retention, stability and support, improves the masticatory efficiency, preserves the alveolar bone and muscular patterns and preserves sensory receptors within the periodontal ligament which increases manipulative skills in handling the denture. Retention and stability of overdentures can be improved by attachments or magnets. Fixed partial denture is not an option when there is no distal abutment. The solution of such a critical situation is to give combined or hybrid prosthesis. A combined prosthesis carries the advantage of fixed removable prostheses without surgical intervention, where an acrylic prosthesis is retained with an extra coronal attachment to tooth. This paper presents a twin patient report of rehabilitation of a mandibular and maxillary terminal dentition with a combined prostheses of acrylic retained by extra coronal precision attachment system (Rhein 83, Italy).","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124781896","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}

Methods: Bovine incisors were ground and cut into six groups (n=10) of cubic samples, set in resin cement such that a single square surface of facial enamel was exposed in each sample. These enamel surfaces were polished and treated, with a group assigned to each of three 5% sodium fluoride varnishes (BISCO, 3M ESPE, GC America), a fluoride foam (Dentsply Sirona), a fluoride gel (Crosstex International, Inc), as well as a water control group. After application of product, the samples were agitated at 37°C before removal of product by potassium hydroxide solution (10mL, 1.0M, saturated with calcium phosphate). A layer of exposed enamel was dissolved in each sample with perchloric acid (2.5mL, 1.0M) which was then neutralized with sodium hydroxide. The resulting solution was buffered in TISAB II and measured for fluoride content by ion selective electrode (ISE), which was adjusted for sample surface area. Results: Enamel each group the following mean values and standard error: 8.32±0.44 μg/cm 2 , 2 , and 4.04±0.20 μg/cm 2 in the BISCO, 3M ESPE, and GC America varnishes, 6.52±0.64 μg/cm 2 in the fluoride foam, 7.03 ± 0.51 μg/ cm 2 in the fluoride gel, and 1.59 ± 0.11 μg/cm 2 in the control group. When in contact with tooth enamel, topical fluoride treatments including varnishes, gels and foams can induce fluorapatite by chemically incorporating fluoride in the tooth structure. This enamel fluoride uptake can be measured and compared to guide clinicians on the relative efficacy of different fluoride treatments. Results demonstrated here show that the BISCO varnish has a statistically higher EFU compared to other tested products.","PeriodicalId":361768,"journal":{"name":"Online Journal of Dentistry & Oral Health","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114495621","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}

This might occur if the fusion between the embryological processes fail. Birth of a baby with a cleft lip or palate is an exhausting and emotional problem which needs Longterm and Multidisciplinary management by plastic surgeon, otolaryngologist, geneticist, pediatrician, social worker, periodontist, orthodontist, and a speech and language specialist The etiology is unknown but there are many predisposing factors which might lead to this defect. Aim: The aim of this study is find out the prevalence of cleft lip and palate and to screen the predisposing factors in newborn babies with cleft lip and palate in Benghazi hospitals Material and method: A Data were Collected from the Archives of Benghazi medical Center and Benghazi Pediatric Hospital to find out the incidence of cleft lip and palate among newborn. the following informations were registered: Date of birth-Birth weight-type of cleft-other congenital defect-age of the mother, her medical condition and drug consumption during pregnancy-age of the father and smoking habit family history of clefts. further Contacts were done by phone calls with the parents to collect more information. full information were acquired from 26 cases out of 43 registered cases of clefts. Statistic analyses using IBM SPSS V.22 Software were done to find out the correlation of predisposing factors with clefts through chi-square. Results: From the recorded 43 cases of cleft lip is 19.5%, cleft palate 48.8%, cleft lip & palate 31.7%. Males were affected more than females (males 65% vs females 35%). in the 26 cases Drug consumption during pregnancy was found 61.5%, mother medical problems 53.8%, family history from the mother side 7.7% and from the father side 11.5%, father smoking habit 46%. Conclusion: The p value from the predisposing factors was insignificant. The male cases rate was higher than females.
