Gray value measurement for the evaluation of local alveolar bone density around impacted maxillary canine teeth using cone beam computed tomography

2021

Background To investigate whether any relationship between local alveolar bone density and maxillary canine impaction using gray values from cone beam computed tomography. Material and Methods The cone beam computed tomography images of 151 patients were retrospectively evaluated. Maxillary canine was defined as an impacted tooth when root formation was complete and the patient’s age older than 13 or the other side of the maxillary canine has completely erupted. Similarly, complete eruption was defined as the tooth in its expected occlusion and position. Using the cone beam computed tomography software, the region of interest which was 5 mm2 in area, was placed in the trabecular bone on cro…

Malignant lymphoma of the oral cavity and the maxillofacial region: overall survival prognostic factors

2013

Objective: To identify the overall survival and prognostic factors of malignant lymphoma of the oral cavity and the maxillofacial region. Study Design: Clinical records data were obtained in order to determine overall survival at 2 and 5 years, the individual survival percentage of each possible prognostic factor with the actuarial technique, and the survival regarding the possible prognostic factors with the actuarial technique and the Log-rank and Cox's regression tests. Results: Of 151 subjects, an overall survival was 60% at 2 years, and 45% at 5 years. The multivariate analysis demonstrated statistically significant differences for clinical stage (p=0.002), extranodal involvement (p=0.…

Total antioxidant capacity of saliva and dental caries.

2013

Objective: Dental caries is one of the most common infectious diseases worldwide. Saliva has many functions in the oral cavity and is the first line defense against dental caries. Oxidative stress can affect initiation and progression of many inflammatory and infectious diseases such as dental caries. Thus the aim of this study was to evaluate the relationship between total antioxidant capacity (TAC) of saliva and dental caries. Study D esign: 100 healthy high school students (50 female and 50 male) with age range of 15 -17 years were randomly selected, divided to four groups. Unstimulated whole saliva specimens were collected at the morning. TAC of saliva was evaluated by spectrophotometri…

Evaluation of the xerostomia, taste and smell impairments after Covid-19

2021

Background The purpose of this study was to explore the effects of coronavirus disease 19 (Covid-19) on the oral cavity by evaluating the oral findings in the patients who recovered after treatment. Material and Methods This study involved confirmed Covid-19 patients whose treatment completed at least two weeks ago. A questionnaire consist of eight parts was applied to explore the oral findings after Covid-19. Also stimulated salivary flow rate was evaluated with a salivary flow test. Results 177 patients reached and 107 of them participate in the study. Regarding gender significant differences were found in terms of the presence of taste impairment after treatment (p=0.007), the degree of …

Versatility of nasolabial flaps in oral cavity reconstructions

2014

Objectives: Describe the techniques involved and the results obtained witn nasolabial flaps in small and medium- sized defects of the oral cavity. The procedure is an easy resconstructive option with a high success rate and with very good aesthetic and functional outcomes. Study Design: A retrospective analysis of 16 nasolabial flap reconstructions in 15 oncological patients with oral cavity defects undergoing single-stage surgical interventions. We evaluate the tumor type, its location, size, the resective and reconstructive techniques involved, as well as any complications. Results: Out of 15 patients, 9 were male and 6 female, with ages ranging from 60-85 years. The primary tumor was loc…

Prognostic factors associated with overall survival in patients with oral cavity squamous cell carcinoma

2020

Background Low socioeconomic status, increasing age, and poor lifestyle behaviors are associated with poor survival in patients with oral cavity squamous cell carcinoma (OCSCC). To determine the overall survival (OS) and the risk of OCSCC death by tumor subsite. Material and Methods A retrospective cohort study of OCSCC patients diagnosed from 2007 to 2009 and treated at a single cancer center in Rio de Janeiro, Brazil. Patient information was obtained from the Hospital Cancer Registry (HCR) database and complemented by individual search of physical and electronic medical records. Descriptive statistics of population characteristics were computed. OS was estimated using the Kaplan-Meier met…

Antibakterielle Konzentrationen in Serum und Geweben aus dem Zahn-Kieferbereich nach perioperativer Einnahme von Propicillin

1983

Nach der operativen Entfernung radikularer und follikularer Zysten im Kieferbereich wurden bei 40 Patienten Serum, Knochen, Zystenbalg und Zystenflussigkeit auf ihren Gehalt an Propicillin untersucht. Die Patienten hatten ein oder zwei Stunden vor der Entnahme der Untersuchungsmaterialien 1 Mega E (0,7 g) Propicillin als Oblongtablette oral erhalten. Ein bzw. zwei Stunden nach der Einnahme des Propicillin betrugen die Verteilungskoeffizienten zwischen Serum und den drei Geweben 0,78 bzw. 0,87 fur die Spongiosa, 0,07 bzw. 0,06 fur den Zystenbalg und 0,14 bzw. 0,08 fur die Zystenflussigkeit. Die mittleren Konzentrationen in allen drei Geweben lagen mindestens zwei Stunden lang deutlich uber d…

Adverse Reactions to Anticancer Drugs in the Oral Cavity

2018

The development, testing, and adoption into clinical practice of anticancer medications have revolutionized cancer care over the past decades. A better understanding of the biology of cancer has translated into development of novel systemic agents, as well a more effective use of older chemotherapy agents. As a consequence, cancer mortality continues to decrease. However, greater cure and disease control rates come at a price of an increased risk of adverse effects, which often affects the mouth and related structures including the oral mucosa, salivary glands, jawbones, and cranial nerves. Oral mucositis, hyposalivation, dysgeusia, and osteonecrosis of the jaw (ONJ) are some examples of th…

Experimental study on the free transplantation of mucosa and lyophilised dura to the oral cavity

1978

Summary The covering of epithelial defects in the oral cavity presents special problems in preprosthetic surgery, since special requisites for function and quality of mucosal grafts must be satisfied. In animal experiments mucosal defects in the oral cavity of 30 rabbits were repaired with free transplants of autologous mucosa and heterologous lyophilised dura. A comparative clinical and histological assessment of the healing processes showed that there was no essential difference between both methods. Considering the necessary second intervention, the infliction of a second wound, as well as the limited source of mucosa, our results show that the use of lyophilised dura in preprosthetic su…
