- Comparing the antibacterial activity of gaseous ozone and chlorhexidine solution on a tooth cavity model(2013) Kapdan, Arife; Öztas,, Nurhan; Sümer, ZeynepObjective: To evaluate the antibacterial activity of gaseous ozone and chlorhexidine solution on a tooth cavity model. Study Design: Twenty-one human molars were divided into 3 groups. Cavities were then cut into the teeth (4 per tooth, 28 cavities per group). After sterilization, the teeth were left in broth cultures of 10 6 colony-forming units (CFU) ml -1 of Streptococcus mutans (S. mutans) at 36°C for 48 h. The appropriate treatment followed (group A, control; group B, 2% chlorhexidine solution; and group C, 80s of treatment with ozone, and the cavities were then filled with composite resin. After 72h, the restorations were removed, dentin chips were collected with an excavator, and the total number of microorganisms was determined. Results: Both of the treatments significantly reduced the number of S. mutans present compared with the control group and there was a significant difference between the all groups in terms of the amount of the microorganisms grown (p < 0.05). Group B was beter than group C; and group C was better than group A. Moreover, it was found that the amount of the growth in the group of chlorhexidine was significantly less than that of the ozone group (p < 0.05). Conclusion: Chlorhexidine solution was the antibacterial treatment most efficacious on S. mutans ; however, ozone application could be an anlternative cavity disinfection method because of ozone's cavity disinfection activity.
- The effect of cigarette smoking on the severity of pain, swelling and trismus after the surgical extraction of impacted mandibular third molar(2013) Al-Delayme, R.E.Objective: The study objective was to investigate the effect of cigarette smoking on the severity of pain, swelling and trismus on male after the surgical removal of impacted lower third molar. Material and Methods: This prospective comparative study was conducted for 150 male in two groups of patients, smokers and non-smokers. Each group consisted of 75 patients; smoking patient were the ones who smoke more than twenty cigarettes per day for more than one year of continuous smoking. Postoperative pain was evaluated using a visual analog scale (VAS) and the degree of swelling was evaluated through facial reference points' variation. The presence of trismus was analyzed through measurement of the interincisal distance (IID). Result: Clinical and radiographic examinations were carried out. Data regarding the age, gender, angulations type, depth and width of impactions were evaluated and analyzed The severity of pain, swelling and trismus on the 1st, 2nd , 5th and 7thday postoperatively was estimated. In both groups the pain and trismus were reported to be in peak level during the first post-operative day while post-operative swelling reaches its peak level in the second postoperative day. Conclusion: Cigarettes smoking do not have any significant relationship with the severity of pain, swelling and trismus after surgical removal of lower third molar on male gender.
- Fibre post behaviour prediction factors: a review of the literature(2013) Bru, Elisa; Forner Navarro, Leopoldo; Llena Puy, María Carmen; Almenar García, Amelia del PilarIntroduction: The advantages of fibre posts over stainless steel posts have been demonstrated in numerous studies. For clinical success, various factors need to be taken into account in post-retained restorations. Material and Methods: A review was made of literature on fibre posts published from 2000 to February 2011, identified through searches of the PubMed/Medline databases. Results: The position of the tooth in the arch, ferrule size, proximal contact, periodontal support and restoration type are survival prediction factors that should be considered when performing post-endodontic restoration. Since fibre posts present good biomechanical behaviour as a result of their elastic modulus, which is similar to that of dentine, treatment failure occurs through decementation rather than because of root fracture, as occurs with metal posts. The shape of the post and, consequently, the thickness of the luting, can modify the retention capacity. Consequently, more anatomically-shaped posts have been developed, as have new techniques to reduce the volume of the dentine/cement interface: lateral condensation, surface remodelling or custom designs. Conclusions: Different aspects of the preparation process can be modified to assist in improving fibre post retention, but further investigation, mainly clinical, is needed to acquire a better understanding of how different factors influence the long-term clinical behaviour of the posts.
- Granular cell ameloblastoma of jaw: report of a case with an emphasis on its characterization(2013) Taneeru, Sravya; Guttikonda, Venkateswara Rao; Yeluri, Sivaranjani; Madala, JayakiranAmeloblastoma is a neoplasm of odontogenic epithelium, especially of enamel organ-type tissue that has not under gone differentiation to the point of hard tissue formation. It accounts for approximately 10% of all tumors originating from gnathic bones. It exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. Granular cell ameloblastoma is a rare condition, accounting for 3.5% of all ameloblastoma cases that shows marked transformation in the cytoplasm of tumor cells, which are usually stellate reticulum like cells. The transformed cells possess very coarse, granular, eosinophilic cytoplasm. The 'granular change' is thought to be due to a dysfunctional status of neoplastic cells, and the pathogenesis of this tumour seems to be age-related. Ultrastructural, histochemical, and immunohitochemical studies have revealed that cytoplasmic granularity is caused by overload; however the mechanism ivolved remains poorly understood. This article describes a case of granular cell variant of ameloblastoma affecting a 55-year old female
- A review of oral biopsies in children and adolescents: a clinicopathological study of a case series(2013) Vale, Edivânia Barbosa do; Ramos Perez, Flávia Maria de Moraes; Rodrigues, Gabryelle Linhares Correa; Carvalho, Elaine Judite de Amorim; Castro, Jurema Freire Lisboa de; Perez, Danyel Elias da CruzObjective: The aim of this study was to evaluate the clinicopathological features of oral lesions in children and adolescents diagnosed in an Oral Pathology Laboratory. Study design: Between 2000 and 2010, all oral lesions diagnosed in patients younger than 18 years old, from the Oral Pathology Laboratory, Federal University of Pernambuco, Brazil, were selected for the study. The clinical data were obtained from the patient charts filed in the Laboratory. All cases were microscopically reviewed and the diagnosis classified into 10 categories. Results: From the 2395 lesions, 315 (13.1%) occurred in this age group. The lesions were more common in the female gender (59%) during the second decade of life (69%). The inflammatory/reactive lesions were the most common (64.4%), followed by the epithelial and soft tissue neoplasms (8.6%). The mucocele (33.3%) was the most common lesion, with the lip mucosa representing the most affected site (48%). In 61.5% there was concordance between clinical hypothesis of diagnosis and histopathological diagnosis. Conclusions: Inflammatory/reactive lesions were the most common biopsied lesions and the lip the most frequent site. Similar studies are important, reinforced by the low correlation between clinical diagnosis and histopathological diagnosis.
- Quality of life in patients with dysphagia after radiation and chemotherapy treatment for head and neck tumors(2013) Campos, Renata Jacob Daniel Salomao de; Palma, Pamella Valente; Leite, Isabel Cristina GonçalvesObjective: The aim of this study is to analyze subjectively, using the SWAL-QOL questionnaire, swallowing dys function and associated factors after treatment with radiotherapy and chemotherapy in patients treated for head and neck cancer. Material and Methods: This is a cross-sectional study, based on the selection of patients with tumors of the head and neck area, treated with radiotherapy with or without chemotherapy during the years 2000 to 2006 at the Oncology Institute of Juiz de Fora. The data were analyzed using SPSS 15.0 software, and were evaluated using the chisquare test to compare differences in proportions between groups. The statistical significance level was set at 5%. Results: It was observed that with respect to foods of solid consistency, there was a statistically significant difference for mouth tumors (p<0.01), with a tendency in this group to use softer foods, easier to chew (stews, boiled vegtables, creamy soups, canned fruit). With reference to the domains of the SWAL-QOL, the location of the tumor in the mouth was statistically associated with the lowest quality of life in the symptoms domain (p<0.05). The female gender variable was associated with the lowest perceived quality of life in several domains, namely swallowing (p=0.02); fatigue (p=0.008); symptoms (p=0.009). Age (split below and above 60 years) was not associated with differences in perceived quality of life in any domain. Conclusion: Tumor in the mouth and the total dose of radiation in the superior fossa were associated with the lowest quality of life in the symptoms domain. The female gender variable was associated with the lowest perceived quality of life in several domains This study shows that speech therapy should maintain a presence in the teams, to then guide the rehabilitation of organic dysphonia and mechanical dysphagia possibly afflicting patients after cancer treatment with radiation therapy and chemotherapy.
- Comparison of the effect of different medicaments on surface reproduction of two commercially available Polyvinyl Siloxane impression materials: an Invitro Study(2013) Singh, Rina; Singh, Jagjit; Gambhir, Ramandeep Singh; Singh, Ramanpreet; Nanda, SoniaObjective:To determine the effect of different retraction cord medicaments on surface detail reproduction of polyvinyl siloxane impression materials and compare this effect on any two brands of commercially available polyvinyl siloxane impression materials. Material and methods: Four stainless steel dies were made according to ADA specification no.19. Three dies were treated with aluminium chloride (5%), ferric sulphate (13.3%) and epinephrine (0.1%) while the fourth one was left untreated to serve as control. Two impression materials (Dentsply and 3M ESPE) were used. Results: All the three medicaments adversely affected the surface detail reproduction of both the brands of the polyvinyl siloxane impression materials. These effects were statistically significant as compared to untreated control. The impressions of 3M ESPE brand have shown better surface detail reproduction as compared to Dentsply impression material. Conclusion: Surface detail reproduction of the polyvinyl siloxane impression materials is adversely affected by the retraction cord medicaments. The presence of moisture or any traces of the medicaments should be removed from the tooth surface to provide a dry field for the correct reproduction of the surface detail of these materials
- Prevalence of tongue lesions in the Indian population(2013) Santosh, Patil; Sumita, Kaswan; Farzan, Rahman; Bharati, DoniObjective: Tongue lesions are a health concern for the dental practitioners and the patients as they constitute a significant proportion of oral mucosal lesions. The aim of the present study was to determine the prevalence of various tongue lesions in the Indian population. Material and methods: 4926 patients attending the Department of Oral Medicine and Radiology were examined for the presence of various tongue lesions during the period from October, 2010 to September, 2012. The age of the patients ranged from 12-80 years with a mean age of 36.51 years. Results: The prevalence of tongue lesions was 12.07%. The most common lesion diagnosed was coated tongue affecting 28.0% of the subjects, followed by geographic tongue (16.4%), fissured tongue (14.9%) and depapillated tongue (11.5%). Males were more frequently affected than females. The most common systemic condition observed in the patients with tongue lesions was anaemia (189), followed by hypertension (47) and diabetes mellitus (38). Conclusion: The high prevalence necessitates adequate awareness of the various tongue lesions in the general population. The dental clinicians should also be knowledgeable about the etiopathogenesis, clinical presentation, diagnosis, and treatment of these lesions.
