Dentin-Hypersensibilit t ist ein einzigartiger Zustand, der durch kurze, stechende Schmerzen gekennzeichnet ist, die vom freiliegenden Dentin als Reaktion auf verschiedene Reize ausgehen. Dieser Schmerz wird in der Regel durch thermische, evaporative, taktile, osmotische oder chemische Faktoren ausgel st und kann nicht auf einen anderen zahnmedizinischen Defekt oder eine Pathologie zur ckgef hrt werden. Am h ufigsten sind die fazialen Wurzeloberfl chen von Eckz hnen, Pr molaren und Molaren betroffen, insbesondere in Bereichen mit parodontalem Attachmentverlust. Die berempfindlichkeit des Dentins kann durch berm igen Abrieb beim Z hneputzen, Parodontalerkrankungen oder Erosion durch Nahrungs- oder Magens uren verursacht werden und kann sich nach Zahnsteinentfernung und Wurzelgl ttung verschlimmern. Das freiliegende Dentin ist berempfindlich, was wahrscheinlich auf das Fehlen des sch tzenden Zementes, den Verlust der Schmierschicht und die hydrodynamische Bewegung der Fl ssigkeit in den Dentinkan lchen zur ckzuf hren ist. Das Ausma der Pulpaentz ndung bei Dentinhypersensibilit t ist nicht genau bekannt, da der Zustand in der Regel nicht schwerwiegend genug ist, um eine Zahnextraktion oder Wurzelkanalbehandlung zu rechtfertigen. Daher wird in diesem Buch der Schwerpunkt auf die Dentin berempfindlichkeit und ihre Behandlung gelegt.

L'ipersensibilit dentinale una condizione unica caratterizzata da un dolore breve e acuto che si origina dalla dentina esposta in risposta a vari stimoli. Questo dolore tipicamente scatenato da fattori termici, evaporativi, tattili, osmotici o chimici e non pu essere attribuito a nessun altro difetto o patologia dentale. La condizione colpisce pi comunemente le superfici radicolari facciali di canini, premolari e molari, soprattutto nelle aree di perdita dell'attacco parodontale. L'ipersensibilit dentinale pu essere correlata a un'eccessiva abrasione da spazzolamento, a una malattia parodontale o all'erosione da acidi alimentari o gastrici e pu essere esacerbata in seguito a procedure di scaling e root planing. La dentina esposta ipersensibile probabilmente a causa della mancanza di cemento protettivo, della perdita dello strato di striscio e del movimento idrodinamico del fluido all'interno dei tubuli dentinali. Il grado di infiammazione pulpare nell'ipersensibilit dentinale non ben compreso, poich la condizione di solito non abbastanza grave da giustificare l'estrazione del dente o il trattamento canalare. Pertanto, in questo libro ci occupiamo dell'ipersensibilit dentinale e della sua gestione.

Root canal treatment is a dental procedure to clean and shape an infected tooth. During treatment several complications may occur among which Endodontic flare up becomes a nightmare for any dental practitioner. It is defined as an acute exacerbation of pain and/or swelling occurring after root canal treatment initiation or during continuation. It presents with an unscheduled patient visit and requires active treatment. Proper knowledge, identification and management of the same is crucial. Prevention focuses on proper diagnosis, strict aseptic techniques, controlled instrumentation, effective irrigation and the use of intracanal medicaments and educating patients about potential post-treatment discomfort and providing postoperative instructions are also essential. This book provides an evidence based guidance for the proper diagnosis and management of flare up cases.

Dentin hypersensitivity is a unique condition characterized by short, sharp pain arising from exposed dentin in response to various stimuli. This pain is typically triggered by thermal, evaporative, tactile, osmotic, or chemical factors, and cannot be attributed to any other dental defect or pathology. The condition most commonly affects the facial root surfaces of canines, premolars, and molars, especially in areas of periodontal attachment loss. Dentin hypersensitivity may be related to excessive tooth brushing abrasion, periodontal disease, or erosion from dietary or gastric acids, and can be exacerbated following scaling and root planing procedures. The exposed dentin is hypersensitive likely due to a lack of protective cementum, loss of the smear layer, and hydrodynamic movement of fluid within the dentinal tubules. The degree of pulpal inflammation in dentin hypersensitivity is not well understood, as the condition is usually not severe enough to warrant tooth extraction or root canal treatment. Thus in this book we emphasize of dentin hypersensitivity and its management.

Dentin hypersensitivity, often called sensitive teeth, is a prevalent dental issue characterized by sharp, transient pain due to exposed dentin responding to thermal, tactile, osmotic, or chemical stimuli. This condition affects many people, impacting their quality of life by limiting dietary choices and causing discomfort during oral hygiene practices.Pain from dentin hypersensitivity typically arises when the protective enamel is worn away or when gum recession exposes the underlying dentin and its microscopic tubules, which connect directly to nerve endings.Contributing factors include aggressive tooth brushing, periodontal disease, acidic dietary intake, and certain dental procedures. Managing this condition effectively involves a combination of preventive measures, such as proper oral hygiene and dietary modifications, along with treatments aimed at desensitizing the nerves or sealing the exposed tubules.Ongoing dental research continues to yield new insights and treatment options for dentin hypersensitivity, promising improved patient outcomes and enhanced quality of life.
