Background: Local anesthetics are utilized all over the world for performing painless dental procedures. Usually, the administration of local anesthetic is an uncomplicated process that passes off uneventfully. Complications, when seen, are not usually serious. However, blindness is an alarming complication both for the patient and for the dentist. Amaurosis can occur with both maxillary and mandibular nerve blocks. Amaurosis is usually associated with other ocular complications like ptosis, diplopia, and periorbital blanching. Case report: We report two rare cases of transient isolated amaurosis. Both the instances of amaurosis were seen after inferior alveolar nerve blocks. The condition was transient and resolved without any active intervention. Discussion: Though permanent amaurosis has been reported, it is usually transient in nature. Various causes have been proposed like intravascular injection, sympathetic impulse generation, and embolism. The etiology in the present case was believed to be intravascular injection. © 2012 Springer-Verlag.

A variety of treatment modalities, from removable partial dentures, fixed prosthesis to implant placement can be used for replacement of missing teeth. Anterior diastema closure is one of the most challenging tasks; it is appreciable that restorative approach is the fastest, simplest and most predictable. This case report presents a successfully accomplished closure of diastema in mandibular anterior teeth, and splinting of the adjacent teeth which were grade II mobile. This present treatment modality offers a conservative, aesthetic and non-invasive treatment which can be considered as a long-lasting treatment.

Objective: To assess the oral health related quality of life among periodontal risk patients before and after periodontal therapy. Method: The study population consisted of 183 patients reporting to the outpatient department of periodontics, who were grouped into low, moderate and high risk patients based on the periodontal risk assessment model. The patients were asked to complete the OHQoL-UK 16 questionnaire before and after periodontal therapy. The change in the patient perception of quality of life before and after treatment was assessed. Results: Periodontitis had a considerable negative impact on the quality of life of patients in the high risk group in comparison to low and moderate risk groups (p<0.001). Treatment brought about an improvement in the OHQoL scores in the moderate and high risk group. Conclusion: This study shows that risk of periodontal disease is significantly related to oral health related quality of life and periodontal therapy improves the quality of life of patients. © BASCD 2012.

Mucosal fenestration is an opening or an interstice through the oral mucosa. A lesion which occurs with greater frequency than generally realised, its occurrence is attributed to a myriad of causes. Mucogingival procedures including connective tissue grafts, free gingival grafts and lateral pedicle grafts are generally considered to be the treatment of choice in the closure of a mucosal fenestration. More often, these procedures are performed in conjunction with other procedures such as periradicular surgery and with bone grafts. However, the concomitant use of gingival grafts and bone grafts in mucosal fenestrations secondary to infections in sites exhibiting severe bone loss is highly debatable. In this article, we report two cases of mucosal fenestrations secondary to trauma and their management by regenerative periodontal surgery with the placement of guided tissue regeneration membrane and bone graft. The final outcome was a complete closure of the fenestration in both the cases.


The present study was primarily carried out to assess the severity of malocclusion and treatment needs of 14- to 15-year-old schoolchildren of Bangalore, India, using the Dental Aesthetic Index (DAI) and to correlate them with the subjective perception of aesthetics, function, speech and treatment needs. A total of 1618 students aged 14 to 15 years, who were randomly selected from 40 government and private schools, were included in the present study. The subjects were asked about their self-perception of malocclusion using a structured questionnaire. A Likert scale was used to assess their perception. They were then subjected to a clinical examination, wherein the malocclusion and the treatment needs were assessed using the DAI. The data were analysed using the SPSS® version 10 statistical package. Most of the subjects were satisfied with the arrangement of their teeth. Weak but statistically significant correlations were found between all of the variables (P < 0.01). Correlation was found to be greater between aesthetics and speech (r = 0.489; P < 0.01), aesthetics and the DAI component (r = 0.342; P < 0.01), and subjectively and objectively perceived treatment needs (r = 0.476; P < 0.01). There was no significant difference observed between the children in private and government schools (P > 0.05). Aesthetics was the most common reason for seeking treatment. Most of the subjects were satisfied with the appearance of their teeth, masticatory function and speech. The perception of dissatisfaction with dental appearance increased with increasing severity of malocclusion. However, the same did not apply for masticatory function and speech. Self-perception of treatment need was low.


External cervical resorption is the loss of dental hard tissue as a result of odontoclastic action; it usually begins on the cervical region of the root surface of the teeth. This case report demonstrates an external cervical resorption in a maxillary central incisor of a 24-year-old male patient. After surgical intervention and root canal treatment, the resorption was subsequently sealed with mineral trioxide aggregate. The 18 months follow-up demonstrates no pathological changes on clinical and radiographic examination. This case report presents a treatment strategy that might improve the healing outcomes for patients with external cervical resorption.

Anterior open bite is often caused by a downward rotation of the mandible and/or by excessive eruption of the posterior teeth. In such cases, it is difficult to establish absolute anchorage for molar intrusion by traditional orthodontic mechanics. This is a case report of successful treatment of a severe anterior open bite using miniscrew anchorage. A female patient of 20 yrs presented with symmetrical frontal facial appearance, increased anterior facial height, convex profile and incompetent lips. Dentally, she had lost both mandibular first molars due to caries and both maxillary first molars were extruded. She had class II canine relationship, 5 mm overjet, 5 mm anterior open bite, 3 mm mandibular midline diastema and a spacing of 2 mm in the maxillary arch. The treatment objectives were to correct the anterior open bite and establish ideal overjet and overbite and to restore the mandibular first molars with fixed prosthesis. Titanium miniscrews (1.3 mm diameter and 9 mm length) were implanted bilaterally in the maxillary arch between the second premolar and the first molar, and an intrusion force was applied with NiTi closed coil springs for 8 months. After molar intrusion, the same screws were used for en masse retraction of the entire dentition (third molars were extracted) for 4 months. The results showed that, after an active treatment of 20 months, the maxillary molars were intruded about 4 mm each and good occlusion was achieved. In conclusion, the miniscrews were very useful in the non-surgical management of adult anterior open bite cases.

This article describes a technique of gap arthroplasty in temporomandibular joint (TMJ) ankylosis performed by transoral access. The treatment of TMJ ankylosis by creating an adequate gap is of paramount importance in preventing any future recurrence and this can be achieved only when good access is gained to this complex anatomical joint. Five patients with TMJ ankylosis (eight TMJ) were treated by gap arthroplasty using an intraoral approach. The average mouth opening before surgery was 8.6 mm and the average mouth opening achieved postsurgery was 37.9 mm. The average follow-up time was 13 months and none of the patients had any recurrence or significant complications during or after surgery. Our technique relies on the use of a stable landmark to trace the superior-most extent of the ankylotic mass thereby facilitating the removal of the entire mass including the medial extent. We found that even though transoral access is technically challenging and took an average time of 84 min, it has many advantages over conventional extraoral approaches in terms of facial scars and facial nerve injury. The authors also emphasize the importance of good postoperative physiotherapy and presurgical patient counselling to prevent future recurrences. © 2014 International Association of Oral and Maxillofacial Surgeons.

Light-emitting diode (LED) light curing units (LCU) have recently been used to polymerize resin-based orthodontic adhesives and preliminary studies indicate their use has been successful. The objectives of this study were to evaluate the shear bond strength (SBS) oforthodontic brackets bonded to enamel with a LED LCU (LEDMAX 4, Hilux, Kulzer comp.) at 10, 20 and 40 seconds and comparing them with that of 40 seconds light exposure from a conventional halogen-based LCU (Hilux unit, Heraeus Kulzer comp.). Also to assess the amount of adhesive remaining on the tooth after debonding using Adhesive Remnant Index (ARI). 120 extracted human premolars were divided into 4 groups of 30 each. After photo polymerization, all the samples were stored in distilled water at 37 degrees C for 24 hours and then subjected to a shear force with universal testing machine until bracket failure. All the recordings were evaluated statistically ANOVA and Turkey tests revealed that, no statistically significant differences were found among the shear bond strengths of 40 sec halogen (10.15 +/- 1.55), 20 sec LED (9.58 +/- 1.71) and 40 sec LED (10.34 +/- 1.83) cured groups; but the bond strength of 10 sec cure LED group (7.56 +/- 1.47) showed significantly lower than the other groups. Chi-square comparisons indicated that there were no significant differences in the ARI scores between the 4 groups tested. The results of this study are promising for orthodontic application of LED curing units in clinics, but further in vivo trials should be performed before validation.

The present study was carried out as a multicenter, randomized controlled, split-mouth clinical trial to evaluate the efficacy of locally delivered lycopene on periodontal health and gingival crevicular fluid (GCF) levels of 8-hydroxydeoxyguanosine (8-OHdG) in smokers and nonsmokers compared with periodontally healthy control subjects. One hundred ten subjects including 50 smokers, 50 nonsmokers, and 10 controls participated in this study. Subjects in the smoker and nonsmoker groups had contralateral sites treated with lycopene gel and a placebo. Clinical parameters included recording site-specific measures of plaque, gingivitis, probing depth, and clinical attachment level. GCF 8-OHdG values were analyzed using a commercially available ELISA kit. Compared with the placebo, lycopene-treated sites in smokers and nonsmokers showed significant reductions in probing depths and gain in the clinical attachment levels. However, there was no statistically significant difference in the clinical parameters when lycopene-treated sites in smokers and nonsmokers were compared, except for the reduction in the 8-OHdG levels. The 8-OHdG levels at 1 week and 3 months in sites treated with lycopene in the smoker and nonsmoker group were comparable with those in the periodontally healthy control group. The gel formulation was effective in increasing clinical attachment and reducing gingival inflammation, probing depth, and oxidative injury compared with the placebo in smoking and nonsmoking subjects.
