ABSTRACT
Talon cusp is a developmental dental anomaly with supernumerary structure projecting from the dento-enamel junction towards the incisal edge of an anterior tooth. The etiology is usually unknown but studies states that talons cusp can occur due to the hyperactivity of the enamel organ during morph differentiation. The incidence is 0.04-10% and the prevalence is more in maxillary incisors than mandibular incisors and more in palatal aspect of the teeth. The most common complications are esthetics, increased risk for caries and occlusal accommodation. This article reports a case of talon cusp on the palatal surface of the permanent maxillary lateral incisor. Due to its clinical significance the dentist should be able to diagnose the supernumerary tooth and definitive treatment should be done.
ABSTRACT
Chlorhexidine is a cationic bisbiguanide with broad antibacterial activity, and wide spectrum of activity encompassing gram-positive and gram-negative bacteria, yeasts, dermatophytes and some lipophilic viruses. Its antibacterial action is due to the disruption of the bacterial cell membrane by the chlorhexidine molecules, increasing the permeability and resulting in cell lysis. Thus, chlorhexidine plays a key role in the dentistry and is used to treat or prevent periodontal disease, and has earned its eponym of the gold standard. This article reviews in detail about the mechanism of action, indications, forms and various studies related to chlorhexidine.
ABSTRACT
OBJECTIVES: The objective was to evaluate the age, gender distribution, side and site distribution, etiology, and common patterns of the mandibular fractures. MATERIALS AND METHODS: This was a systematic retrospective review of records of 94 patients with 162 mandibular fractures treated in a single institution. RESULTS: Of 94 patients, 72 male and 22 female patients belong to the age group of 4-62 years (average 31.57 years). Among the various etiologies, i.e., assault, road traffic accident (RTA), self-fall, workplace injury, and sports-related injury, RTA accounts for 62.76% and self-fall for 18.08% of cases. Of the 100 fractures analyzed, 46% are unilateral fractures and 54% are bilateral. Sides affected among these are left (58%), right (39%), and symphysis or midline (3%). The site distribution is as follows: symphysis - 5; parasymphysis - 64; body - 13; angle - 43; and subcondylar - 37. The most common fracture pattern is the ipsilateral parasymphysis with contralateral angle (21 cases). Open reduction and internal fixation was the predominant modality of treatment. Complications were observed in 27.65% of patients. CONCLUSION: Surveys play a vital role in better understanding the biomechanics of the mandible fractures. Furthermore, analysis of the treatment modalities used and their respective outcomes are of paramount importance in guiding surgeons to evaluate their efficacy.
ABSTRACT
AIM: The present study was conducted with the aim of evaluating the effectiveness of antimicrobial therapy following extraction of an impacted mandibular third molar. MATERIALS AND METHODS: This randomized controlled trial was conducted on a total of 60 patients who were randomly assigned into three groups: Group I individuals were given 625 mg of combined amoxicillin and clavulanic acid tablet; 625 mg of combined amoxicillin and clavulanic acid tablet + 400 mg metronidazole tablet was given to group II individuals; whereas group III individuals were assigned no treatment. All the individuals underwent surgical extraction of impacted mandibular third molars under strict aseptic techniques, with minimal trauma to the surrounding tissues. Mouth opening in millimeters was recorded postoperatively using Vernier calipers on the 1st, 3rd, 5th, and 7th days. A 4-point visual analog scale (VAS) was used for assessing postoperative pain. Patient satisfaction was further assessed in a subjective manner using a graded scale from "very satisfied" to "very unsatisfied". RESULTS: The present study included individuals between the ages of 20 and 35 years. Group II individuals showed slightly better satisfaction than the other group individuals. There was no statistically significant difference between the mean age of groups. It was observed that on day 3, the number of individuals with severe pain was slightly reduced in the group I compared with group III individuals. On day 5, participants with no pain were significantly more in group II followed by group I. Furthermore, there was a statistically significant difference between the study groups with respect to mouth opening on days 3 and 5. CONCLUSION: It was concluded from this trial that the administration of postoperative antimicrobials showed no significant differences in the degree of postoperative complications that occur following the surgical extraction of impacted mandibular third molars. CLINICAL SIGNIFICANCE: Antimicrobial drugs are routinely used to reduce the chances of surgical site infection, either preopera-tively or postoperatively. Therefore, the clinicians should have sound knowledge about choosing the better antimicrobial drug after the extraction of impacted third molars.
