Skillful management of exodontia complication to prevent dreadful sequelae
2011
Successful surgical treatments depend upon accurate diagnosis, judicious treatment planning, selection and execution of an appropriate surgical technique, and on a well monitored post-operative period. However, despite these precautions, extraction of teeth (particularly third molar) is exposed to the accidents and complications common to all buccomaxillary and facial interventions. A maxillary third molar may be displaced in maxillary sinus, nearby soft tissue, or may migrate in a superioposterior direction towards paraphyrangeal space, or infratemporal fossa. Dislocating the maxillary third molar in infratemporal fossa is one of the worst nightmare as this area has complex anatomy consist…
Obstetrics outcomes after complete and partial molar pregnancy: Review of the literature and meta-analysis.
2021
The hydatidiform mole is a rare gynecological disease rising from the trophoblastic. Post-molar pregnancies have an extremely variable course, varying from repeated abortions, stillbirths, preterm births, live births, or recurring in further molar pregnancies. Literature on obstetric outcomes following molar pregnancy is poor, often including monocentric studies, and with data collected from national databases. This review and meta-analysis aim to analyze the obstetric outcomes after conservative management of complete (CHM) and partial (PHM) molar pregnancies. The meta-analysis was performed following the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) and the preferred repo…
Pericoronitis: A clinical and epidemiological study in greek military recruits
2019
Background This paper presents a statistical analysis of epidemiological, clinical and radiographical characteristics of third molar-related pericoronitis. Material and methods 650 conscripts of the First Training Division of Conscript Soldiers of 2005 in Greece were recruited for the study. Each conscript was given a questionnaire and underwent a clinical test and a radiographic examination. The tested variables included the conscripts' personal information, oral hygiene parameters along with the radiographic angulation of the third molar, the level of impaction and their classification in relation to the edge of the mandible. Results The prevalence of pericoronitis was found to be 4.92%. …
Extraoral surgical removal of an ectopic impacted third molar of the mandible. Report of a case
2020
Intraoral approach for the removal of impacted third molars represents a common surgical procedure for the specialized clinician. However, in some cases such as ectopic third molars, extraoral surgical removal seems to be inevitable. We present a step by step case of a 56 year old woman with an ectopic third molar of the lower jaw along with a cystic lesion, which were surgically removed by a submandibular approach. Postoperative clinical course was uneventful and there were no signs of facial nerve paresis. In such cases, appropriate preoperative planning must be made based on careful study of radiographic imaging and clinical examination. The more conservative technique that would minimiz…
Repercussions of intraalveolar placement of combination of 0.2% chlorhexidine & 10 Mg metronidazole gel on the occurrence of dry sockets- A randomize…
2017
BACKGROUND To evaluate the effects of intraalveolar placement of gel containing 0.2% chlorhexidine and 10gm of metronidazole on the incidence of alveolar osteitis. MATERIAL AND METHODS A total of 300 impacted third molars were extracted in 150 patients enrolled in this trial. In each subject a socket was randomly selected and packed to the crest of alveolar ridge with the gel. The contralateral socket was packed with placebo dressing. The occurrence of dry socket was assessed during 3rd and 5th postoperative days .The data was analysed using a meta analytical program. STUDY DESIGN Double blind, prospective, placebo controlled trial. RESULTS The combination of metronidazole + chlorhexidine g…
Dentigerous cyst with parietal and intracystic calcifications: a case report and literature review
2018
Background Dentigerous cyst appears surrounding the crown of an included tooth. On the radiographic exam, a radiolucent rounded well-defined lesion can be observed. Material and methods This study reports a clinical case of a 34-years old man with a pericoronal radiolucent lesion associated to an impacted lower third molar with the presence of radiopaque material inside. The radiological differential diagnosis was calcifying odontogenic tumor, adenomatoid odontogenic tumor and dentigerous cyst. The impacted third molar was removed and the lesion was sent for the histopathological exam. Results The histopathological diagnosis was dentigerous cyst with capsular calcifications. Specifically, p…
Radiographic technical quality of root canal treatment performed ex vivo by dental students at Valencia University Medical and Dental School, Spain
2013
Objectives: To evaluate radiographically the quality of root canal fillings and compare manual and rotary preparation performed on extracted teeth by undergraduate dental students. Study Design: A total of 561 premolars and molars extracted teeth were prepared using nickel-titanium rotary files or manual instrumentation and filled with gutta-percha using a cold lateral condensation technique, by 4th grade undergraduate students. Periapical radiographs were used to assess the technical quality of the root canal filling, evaluating three variables: length, density and taper. These data were recorded, scored and used to study the “technical success rate” and the “overall score”. The length of …
Salivary myeloperoxidase and malondialdehyde are increased in patients exhibiting an asymptomatic mandibular impacted third molar
2019
Background To determine whether saliva is a good means of evaluating concentrations of oxidative stress biomarkers, analyzing the correlation between concentrations in saliva and in follicular tissue, and to compare biomarker concentrations in patients with one asymptomatic mandibular impacted third molar (MITM) (before extraction) with a healthy control, and to determine how biomarkers are modified by extraction. Material and Methods 80 patients with one asymptomatic MITM and 80 healthy controls were included. Saliva samples were collected from all subjects (before extraction in the study group) to evaluate Myeloperoxidase (MPO) and Malondialdehyde (MDA) concentrations. Follicular tissues …
RT-qPCR study of COX-1 and -2 genes in oral surgical model comparing single-dose preemptive ibuprofen and etoricoxib: A randomized clinical trialy
2019
Background This study aimed to evaluate the gene expression of cyclooxygenases (COXs) in an oral model of preemptive analgesia. Material and Methods Gingival tissue was collected during extraction of lower third molars from a randomized, triple-blind, split-mouth and placebo-controlled study. The eligible patients were randomly sorted to receive a single dose either of ibuprofen 400mg, or etoricoxib 120 mg or a placebo, one hour prior to surgery. The temporal course of RNAm was evaluated for COX-1 and -2 by means of a quantitative polymerase chain reaction in real time (RT-qPCR) at time zero and 30 minutes after the surgical procedure began, and it was correlated with clinical parameters (p…
Efficacy of fentanyl transdermal patch in pain control after lower third molar surgery: A preliminary study
2015
Background Surgical removal of impacted lower third molars is a common oral surgical procedure, generally followed by moderate to severe postoperative pain. Transdermal drug delivery as a concept offers interesting possibilities for postoperative pain control. The aim of this study was to evaluate the efficacy of transdermal system with fentanyl in relieving pain following impacted lower third molar surgery. Material and Methods Seventeen patients with bilateral impacted lower third molars were included in this preliminary study. For postoperative pain control, patients randomly received a fentanyl patch plus placebo tablet after the first operation and regular (placebo) patch and an analge…
