Under block anesthesia the clot devoided socket with whitish and necrosed appearance was thoroughly curetted, both from the floor of the socket as well as from the bony walls, the sharp margins were trimmed, rounded and any foreign bodies if present were thouroghly removed. The detached gingival margins were also scraped with the help of sharp instrument like Bared Parker knife No=11. The whole above-mentioned procedure .The desired medications as well as precautions were thoroughly explained to the patient.It was almost always that the patient was not only without pain, but was also comfortable both physically as well as psychologically from the very next day.
Shock is a medical emergency in which the organs and tissues of the body are not receiving an adequate flow of blood. This deprives the organs and tissues of oxygen (carried in the blood) and allows the buildup of waste products. Shock can result in serious damage or even death.

INTRODUCTIONScience the earliest period of history of the extraction of thetooth has been considered a very formidable procedure by thelayman, & it is because of the horrifying experiencesassociated with the tooth extraction in the past that eventoday the removal of a tooth is dreaded by a patient almostmore than any other surgical procedure.Many patients suffer from extractionfobia & are often difficult tocare for, despite modern methods of anesthesia.Many dentists still believe that speed is essential whenextracting the teeth.
DEFINITION• The ideal tooth extraction is –The painless removal of the whole tooth, orroot, with minimal trauma to the investing tissues, so thatthe wound heals uneventfully & no post-operativeprosthetic problem is created.(Geoffray L Howe)
The 1st dentist was an EGYPTIAN– HESI RE (3100-2181BC)The history of dental extraction forceps is very old andgoes back to the time of Aristotle (384 to 322 BC)where Aristotle described the mechanics of oral surgeryforceps .This was over 100 years beforeArchimedesstudied and discussed the principles of the lever.

until the 16th century, dedicated dentists did not exist anddentistry was practiced by general physicians and barbers. A number of tools were invented for performing this procedure.Dental Pelican, which was invented in the 14th century by Guy deChauliac and used until the late 18th century.
The instrument is a combination of theattributes of the an extracting forceps and atoothkey 1843 to 1863In the 20th century, the key was replaced bythe forceps, which are still in use today

Piezosurgery is an innovative bone surgery technique that producesa modulated ultrasonic frequency of 24 to 29 kHz, and amicrovibration amplitude between 60 and 200 mm/s. The amplitude of the vibrations created allows a very clean andprecise surgical cut. It works selectively, without harming soft tissues such as nerves andblood vessels even with accidental contact with the cutting tip. The surgical control of the device is effortless compared withrotational burs or oscillating saws because there is no need for anadditional force to oppose rotation or oscillation of the instrument.
Despite the longer time of the procedure, the investigators alsonoted that the piezoelectric osteotomy reduced postoperativefacial swelling and trismus. Uses of piezosurgery device to cut and elevate a precisely definedbone lid on the lateral cortex of the mandible to provide access tothe teeth needing extraction or even a lesion that needs to beexcised. The bone window is then elevated with the help of a curvedosteotome. After the visual confirmation of an undamaged IAN and adjacenttissues, the bone lid is placed back into its original position andfixated with absorbable miniplates.
For the surgical extraction of the teeth, the covering bone was firstablated, layer by layer, using the Er:YAG laser. In the case of the fiber-optic Er:YAG [erbium:yttrium-aluminumgarnet ], laser the fiber is closely guided around the teeth, creating anarrow gap with minimal bone loss. The benefits of laser therapy include the creation of a bloodlesssurgical field and thus improved visualization during surgery,decreased postoperative pain, and limited scarring and contraction. Time consuming, sound and smell, significantly inhibition thelaser cutting because of the overall volume of irrigation and bloodcovering the bone surface.
Third molars in close proximity to the IAN have a significantnegative impact on recovery for pain and oral function. The advantage of this technique is that the risk of direct traumato the nerve is eliminated, due to both the increased distancebetween the roots and the mandibular canal and the decreased needfor surgical manipulation during the extraction.
A potential problem with this technique is soft tissue damage fromimpingement on the mucosa of the cheek and the gingiva. In addition, working in this area of the mouth presents greatdifficulty, and the action of the masseter muscle leads to cheekcompression against the orthodontic appliances. This technique will be of no value for a tooth that cannot movebecause of ankylosis. This technique should be used only in carefully selected cases inconjunction with an orthodontist, being certainly difficult, timeconsuming, and not always successful.
Panoramic radiograph at initial consultation. The mandibularthird molars are mesially impacted with the roots close tothe alveolar canal.
Postoperative radiograph after second sectioning ofthe right mandibular third molar. A pulpotomy has been performed.More space was created distal to the right mandibular secondmolar to allow further migrationPostoperative radiograph after the right mandibularthird molar was surgically sectioned. The spacedistal to the second molar would allow mesialmigration of the impacted tooth.
3 months after odontectomy. Thethird molar moved mesially.However, the mesial root was stillin contact with the alveolar canal.A second sectioning was required.Periapical radiograph obtained 2 months aftersecond sectioning. At that time, the roots wereaway from the alveolar canal, and a risklessextraction could be scheduled.
The Physics Forceps uses first-class level mechanics to atraumaticallyextract a tooth from its socket. One handle of the device is connected to a “bumper,” which acts as afulcrum during the extraction. Together the “beak and bumper” design acts as a simple first-classlever. A squeezing motion should not used with these forceps. By contrast, thehandles are actually rotated as one unit using a steady yet gentlerotational force with wrist movement only. Once the tooth is loosened, it may be removed with traditionalinstruments such as a conventional forceps

Coronectomy can be beneficial but success requires both good patientselection and operator technique. Renton et al.reported no IDNI in 58 successful Coronectomy patientsand a 19% IDNI rate in those having traditional extractions. Leung et al. showed nine (5%) patients in the control group presentedwith IDNI, compared with one (0.06%) in the Coronectomy group. Hantano et al. reported that in the extraction group six patients (5%)suffered IDNI, of which 3 patients were diagnosed with permanentinjury, where as in the Coronectomy group one patient (1%)complained of altered sensation post-operatively which resolved withinone month. The retrospective analysis of O’Riordan consisted of 52 patients thatunderwent Coronectomy. In this study there were 3 cases of transientIDNI which showed resolution one week post operatively. One patientdeveloped permanent IDNI, which was thought to be as a result ofperforation of the canal due to operator error rather than theCoronectomy technique itself.

To avoid traumatizing the surrounding bone during elevation,implant drills were placed in the root canals to thin the root wallsgiving way to extraction with the application of much less force,thereby decreasing the chance of traumatizing the thin buccal bone.

Mostly 1–3 days after tooth extraction . Within a week - In 95% and 100% of all cases. Unlikely - before the first postoperative day.because the blood clot contains anti-plasmin that must beconsumed by plasmin before clot disintegration can take place. The duration of alveolar osteitis varies to some degree, depending onthe severity of the disease, but it usually ranges from 5–10 days.
1. The denuded alveolar bare bone may be painful and tender.Initially blood clot appears dirty gray disintegratesgrayish yellow bony socket bare of granulation tissue2. Some patients may also complain of intense continuous painirradiating to the ipsilateral ear, temporal region or the eye.3. Regional lymphadenopathy (occasionally).4. unpleasant taste (occasionally).5. Trismus is a rare occurrence in mandibular third molar extractionsprobably due to lengthy and traumatic surgery.
Multifactorial origin Following have been implicated most commonly as etiological,aggravating and precipitating factors:1. Oral micro-organisms - Treponema denticola2. Difficulty and trauma during surgery3. Roots or bone fragments remaining in the wound4. Excessive irrigation or curettage of the alveolus after extraction5. Physical dislodgement of the clot6. Local blood perfusion & anesthesia7. Oral contraceptives - estrogens, like pyrogens will activate thefibrinolytic system indirectly.8. Smoking
1. Previous experience.2. Deeply impacted mandibular third molar (risk factor is directlyproportional to increasing severity of impaction) .3. Poor oral hygiene of patient .4.

References in the literature correlating to theprevention of alveolar osteitis can be dividedinto1. Non-pharmacological and2. Pharmacological preventive measures.
Non-pharmacologicalmeasures1. Use of good quality current preoperative radiographs2. Careful planning of the surgery3. Use of good surgical principles4. Extractions should be performed with minimum amount oftrauma and maximum amount of care5. Confirm presence of blood clot subsequent to extraction(if absent, scrape alveolar walls gently)
6. Wherever possible preoperative oral hygienemeasures to reduce plaque levels to a minimumshould be instituted7. Encourage the patient (again) to stop or limit smokingin the immediate postoperative period .8. Advise patient to avoid vigorous mouth rinsing for thefirst 24 h post extraction and to use gentletoothbrushing in the immediate postoperative period .9. For patients taking oral contraceptives extractionsshould ideally be performed during days 23 through28 of the menstrual cycle .10. Comprehensive pre- and postoperative verbalinstructions should be supplemented with writtenadvice to ensure maximum compliance .
1. Remove any sutures to allow adequate exposure of the extraction site.Asthe socket may be exquisitely tender local anaesthesia may be required.2. Irrigate the socket gently with war sterile isotonic saline or local anaestheticsolution, which is followed by careful suctioning of all excess irrigationsolution.3. Do not attempt to curette the socket, as this will increase the level of pain.4. Prescription of potent oral analgesics.5. The patient is given a plastic syringe with a curved tip for home irrigationwith chlorhexidine solution or saline and instructed to keep the socket clean.6. Once the socket no longer collects any debris, home irrigation can bediscontinued.
Under block anesthesia The clot devoided socket is thoroughly curetted, both from thefloor of the socket as well as from the bony walls. The sharp margins were trimmed, rounded. Any foreign bodies if present were thouroghly removed. The detached gingival margins were also scraped. The desired medications as well as precautions . Patient was not only without pain, but was also comfortable bothphysically as well as psychologically from the very next day.S.C.Anand,V. Singh, M. Goel, A.Verma, B.
