Introduction: Standard local anaesthetics do not guarantee complete absence of pain during endodontic debridement of the in lamed pulp. We investigated whether the addition of mg of morphine to local articaine anaesthesia as compared to articaine alone could reduce pain sensations during endodontic debridement and within h after the procedure. Materials and methods: Thirty-two patients with pain attributed to irreversible pulpitis of the irst upper molar participated in this randomized, double-blind trial. Patients were randomly assigned either to the study group (patients receiving periapical injection of modi ied local anaesthetic solution with morphine, n = ) or to the control group (patients receiving standard anaesthetic solution without morphine, n = ). The pain intensity was assessed using the visual analogue scale and verbal score before and directly after endodontic debridement, as well as at , , , , and h after the procedure. Results:Neither the visual analogue scale nor verbal score differed between both groups before or during the endodontic debridement, as well as during -hour follow-up. However, there was an insigni icant tendency for greater pain relief in patients treated with articaine and morphine at h after endodontic debridement (p = . ). The study was funded by a Jagiellonian University in Poland (JU) grant, and was registered with the JU Ethical Committee No. /K/ZDS/ . Conclusions: The addition of morphine to local articaine anaesthesia does not in luence pain intensity in patients undergoing endodontic debridement in contrast to the previously described pain-relief effect in patients after oral surgery. However, future studies are needed to evaluate the role of opioids in local anaesthesia in endodontic procedures. Keywords: pulpitis; endodontic debridement; articaine; morphine; pain. ABSTRAKT Wstęp: Standardowe znieczulenie miejscowe nie gwarantuje całkowitego ustąpienia bólu podczas zabiegu endodontycznego usuwania miazgi w stanie nieodwracalnego zapalenia. Celem pracy było sprawdzenie, czy miejscowe znieczulenie za pomocą mor iny w dawce mg dodanej do standardowego znieczulenia za pomocą artykainy w porównaniu z samą artykainą zmniejszy odczuwanie bólu w czasie godz. po zabiegu endodontycznym. Materiały i metody: W podwójnie ślepej próbie klinicznej uczestniczyły osoby, które miały nieodwracalne zapalenie miazgi pierwszego zęba trzonowego szczęki. Uczestnicy badania byli zrandomizowani do dwóch grup: grupy badawczej, która otrzymywała artykainę i mor inę (n = ), oraz grupy kontrolnej, która otrzymywała tylko artykainę (n = ). Nasilenie bólu badano za pomocą numerycznej skali oceny bólu oraz skali wzrokowo--analogowej przed zabiegiem oraz , , , , i godz. po zabiegu.Wyniki: Nie stwierdzono istotnych różnic nasilenia bólu między dwoma grupami w obu skalach oceny bólu we wszystkich kolejnych punktach oceny aż do godz. po zabiegu. Stwierdzono jedynie nieistotne statystycznie mniejsze odczuwanie bólu po godz. u chorych leczonych mor iną i artykainą (p = , ). Badanie było inansowane z ...
Introduction: Impacted upper central incisors are a big aesthetic, developmental and social problem for patients. One of the causes of tooth eruption is dilaceration, which is the angulation of the tooth root in relation to its crown. The prognosis regarding the possibility of introducing teeth with dilaceration to the dental arch is uncertain and is characterized by a large number of failures. The aim of the study was to conduct a systematic review of the literature discussing the subject of impacted upper central incisors with confirmed dilaceration and illustrate this problem with the presentation of our own clinical case. Objectives: The aim of the study was to conduct a systematic review of the literature discussing the subject of impacted maxillary central incisors with confirmed dilaceration and to illustrate this problem with the presentation of a clinical case. Material and methods: A systematic review of the literature was conducted by searching the medical databases of PubMed and Scopus. The search was carried out by entering the following keywords: dilaceration, impacted tooth, impacted maxillary central incisors. Non-systematic reviews of the literature were excluded from the analysis. Results: The result of searching the databases was a total of 706 articles. Twenty-nine articles corresponding to the objectives of the study were included in the analysis. Among them were original papers, meta-analyses and case reports. The problem of impacted upper central incisors with the diagnosed dilaceration is illustrated by the description of the orthodontic and surgical treatment of the case. Conclusions: Patients with diagnosed impacted tooth with dilaceration require detailed diagnostics to plan orthodontic treatment. The implementation of a comprehensive orthodontic and surgical treatment at an early stage of tooth development gives the best prognosis to introduce a tooth with dilaceration to the dental arch.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
