Frequency of postoperative sensitivity in posterior class I composite restorations

The growing demand for esthetic restorations has driven the dentists to provide composite resin restorations even in the posterior class I situations. In these load bearing locations of the teeth, composite resins are subjected to a very thorough biodynamic testing which revealed some of their shortcomings. Persistent postoperative sensitivity has been recognized to be a reason for failure of these restorations. The objective of this study was to determine the frequency of postoperative sensitivity in posterior class I composite restorations placed in cavities less than or equal to a 3 mm depth. A total of 292 cavities were restored without any protective liners or base by one of the authors in an academic environment which were followed up at 48 hours for an objective cold test. The frequency of postoperative sensitivity was around 13% and no statistically significant relationship was found between patient age and tooth type [p value > 0.000]. While the cavity depths were limited the buccolingual widths remained unchecked and in some cases resulted in considerable occlusal table correction. This may be the reason for a greater postoperative sensitivity in the present study

Treatment of acute apical abscess by single visit endodontics - 2 case reports

The purpose to publish these case reports is to show the effectiveness of single visit endodontics in teeth with acute apical abscess. Infected non-vital teeth in two patients were treated with single visit RCT along with incision and drainage of the abscess in the same appointment. Follow up of both the patients showed relief of symptoms to remarkable extent in the evening of treatment day. Radiographs showed significant periapical bone healing after 3 months in both patients

Level of pain experience of patients during endodontic treatment procedures in the Islamic international dental college

To report the pain experienced by the patient during the endodontic procedure and correlate this-with age and gender of the patient, tooth type, arch, pulpal diagnosis and stage of endodontic procedure. Eighty five patients with ages ranging between 8- 60 years who reported to the Islamic International Dental College for endodontic treatment were consecutively selected. A 10-point visual analogue scale [VAS] was used to rate the level of pain suffered during the treatment session. The mean pain score was 1.75 for all patients with a mean of 1.33 for men and a mean of 2.38 for women. 50.5% of patients reported no pain; severe pain occurred in only 6[7.1%] of patients. No significant correlation was found for age but the pain experience of patients aged 50 and above was less. Obturation procedures were the least painful with access cavity preparations resulting in the greatest number of patients experiencing severe pain. Pain experienced during endodontic procedures is greater during access cavity preparation [51.7%] and canal preparation [64%]. Sever pain was more reported for female patients, posterior teeth and teeth with pulpitis
