Efficacy of platelet-rich plasma applied to post-extraction retained lower third molar alveoli. A systematic review
Dental retentions have a high prevalence among the general population and their removal can involve multiple complications. The use of platelet rich plasma has been proposed in an attempt to avoid these complications, as it contains high growth factors and stimulates diverse biological functions that facilitate the healing of soft and hard tissues. Objectives: To evaluate the available scientific evidence related to the application of platelet-rich plasma in the post-extraction alveoli of a retained lower third molars. Material and Methods: A systematic review of published literature registered in the Medline, EMBASE, Cochrane and NIH databases. The following categories were included: human…
Comparison of peri-implant soft tissues in submerged versus transmucosal healing: A split mouth prospective immunohistochemical study
Objective The present split-mouth prospective study involves an immunohistochemical evaluation of peri-implant soft tissue healing after the osseointegration period, comparing submerged and transmucosal approaches using two-piece implant systems. The null hypothesis was that both surgical procedures elicit a similar immune response of the peri-implant soft tissues. Design Thirty-one healthy patients were included in this study, in which two implants were placed in the right and left maxillary pre-molar regions. A total of 62 dental implants were analyzed, establishing a control side with 31 submerged implants, and a study side with 31 exposed implants bearing healing abutments. After a thre…
Masseter and temporalis muscle electromyography findings after lower third molar extraction.
Background The main clinical application of electromyography is to detect abnormalities in muscle function, to assess muscle activity for purposes of recruitment, and in the biomechanics of movement. Objectives To analyze electromyography (EMG) findings for masticatory muscles during chewing following surgical extraction of lower third molars, and to determine any correlation between pain, inflammation, trismus, and the EMG data registered. Material and Methods This prospective study included 31 patients. Surface EMG was used to study masseter and temporalis muscle function before lower third molar extraction and 72 hours and seven days after surgery. Clinical variables, pain, inflammation,…
Odontostomatological therapeutic possibilities in patients with sleep apnea
Objectives: To evaluate the different therapeutic possibilities for treating Sleep Apnea/ Hypoapnea Syndrome (SAHS), as well as the effectiveness of such treatments, and to evaluate the epidemiological and clinical aspects of this syndrome. Study design: We carried out a meta-analytical, observational and retrospective study by selecting a total of 13 articles, which provided a sample size of 642 diagnosed cases of SAHS. Results: SAHS was more prevalent among males (88.7%) and the average age of diagnosis was 49.75 years old. In the majority of cases, these patients were found to be overweight, with an average body mass index of 28.32 Kg/ m². The average apnea / hypoapnea index was 31.64 ap…
Clinical repercussions and epidemiological considerations of supernumerary canines : a 26 case series
Background To establish the prevalence of supernumerary canines (SNC) in a sector of the population of Madrid (Spain), as well possible complications associated with this unusual developmental variation. Material and Methods This observational study was performed between 2005 and 2017, among 21,615 patients seeking dental treatment at the Faculty of Dentistry, Complutense University of Madrid (Spain), and at the Virgen de la Paloma Hospital, Madrid (Spain); 22 patients with 26 SNCs were diagnosed. These 22 patients underwent clinical and radiological exploration, registering patient data. Results SNCs presented a prevalence of 0.10% of the study population. The supernumerary teeth (SNT) wer…
Quantification of growth factors by using a new system for obtaining platelet-rich plasma
Objective: To verify the performance of a new method for obtaining platelet-rich plasma, while avoiding contami- nation of the sample during its processing. Study Design: Twenty healthy patients were selected, from whom 21 ml of blood was etracted. �e then pro- Design: Twenty healthy patients were selected, from whom 21 ml of blood was etracted. �e then pro- esign: Twenty healthy patients were selected, from whom 21 ml of blood was etracted. �e then pro- ceeded to study the platelets and growth factors in basal blood after centrifuging the sample by using a new closed system for obtaining platelet-rich plasma (PRP). Results: After centrifuging the blood sample, double the amount of platelet…
Evaluation of the anaesthetic properties and tolerance of 1:100,000 articaine versus 1:100,000 lidocaine. : a comparative study in surgery of the lower third molar
Objectives: To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. Study Design: A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,000. The variables analysed were latency period, duration of anaesthetic effect, tolerance and adverse reactions. Results: Both the latency period and the duration of anaesthetic effect were greater for articaine, although the differences were not statistically significant. Latency: mean difference of…
