Role of surface topography of titanium endosseous implants for improved osseointegration

Osseointegration is the basis of successful endosseous implantology. The process itself is complex, and many factors influence the formation and maintenance of bone at the implant surface. Studies have shown that implant-tissue interface can be influenced by different methods of surface treatment that affect the biologic response to the implant. Methods of surface treatment include alteration of the microstructure and physicochemical parameters of the implant surface.

A modified approach of impression technique for fabrication of finger prostheses.

Background and Aim: The custom-made finger prosthesis is aesthetically acceptable and comfortable for use in patients with amputated fingers, resulting in psychological improvement and physiological well being. The success of the prosthesis depends on the precision of planning the prosthesis, making the impression, carving the model and choosing the material that best suits the concerned circumstances. In this article a simplified method was used regarding an accurate impression of partially amputated fingers. Technique: A plastic cylindrical small open container (impression cap) was used for making an impression of the fingers. A wax pattern of the missing part was made by replicating the same fingers of the other hand with melted modelling wax after slight modification. This pattern was finally cured with silicone material. Discussion: In the present technique, a modified approach of impression making was used for getting an accurate fit of the finger prosthesis with improved aesthetics, which is one of the most important criterion for the success of any prosthesis. Clinical relevance The present article provides a simplified approach for fabrication of partially lost finger prosthesis.

Impact of Different Prosthodontic Treatment Modalities on Nutritional Parameters of Elderly Patients

PURPOSE To assess dietary and nutritional changes among the elderly following pros-thodontic rehabilitation. Another objective was to study the relationship, if any, between diet and nutrition, with extent of edentulism and different types of prosthodontic treatment. MATERIALS AND METHODS One hundred and thirty-five patients who satisfied the inclu-sion and exclusion criteria and agreed to be a part of the study after informed consent were recruited to this longitudinal study. Following selection, they were investigated on four aspects: dental examination, dietary assessment, anthropometric assessment, and serum biochemical assessment. All measurements were collected twice, first at baseline and then 6 months following prosthodontic rehabilitation. Treatment modalities included were complete denture (CD), removable partial denture (RPD), and fixed partial denture (FPD). The RPD group was of two types: distal extension prosthesis (RPDD) and tooth-supported prosthesis (RPDT). Change (post-pre) in outcome measures was compared by one-way ANOVA, and significance of mean difference between the groups was done by Tukeys honestly significance difference post hoc test. RESULTS The improvement in diet was found to be: CD > RPDD > RPDT > FPD. Significant improvement in weight (p < 0.001), BMI (p < 0.001), protein (p < 0.001), carbohydrate (p = 0.021), calorie (p < 0.001), iron (p = 0.002), and vitamin B (p < 0.001) in group CD as compared to partially edentulous patients (group RPDD + RPDT + FPD) was noted. The protein and calorie intake increased significantly in group RPD as compared to group FPD in partially edentulous patients. CONCLUSION Prosthetic rehabilitation becomes increasingly important as the level of edentulism increases to improve dietary, anthropometric, and biochemical parameters.

Mercury and other biomedical waste management practices among dental practitioners in India.

Objectives. The objective of the study was to assess the awareness and performance towards dental waste including mercury management policy and practices among the dental practitioners in North India. Materials and Methods. An epidemiologic survey was conducted among 200 private dental practitioners. The survey form was composed of 29 self-administered questions frame based on knowledge, attitude, and those regarding the practices of dentists in relation to dental health-care waste management. The resulting data were coded and a statistical analysis was done. Results and Discussion. About 63.7% of the dentists were not aware of the different categories of biomedical waste generated in their clinics. Only 31.9% of the dentists correctly said that outdated and contaminated drugs come under cytotoxic waste. 46.2% said they break the needle and dispose of it and only 21.9% use needle burner to destroy it. 45.0% of the dentists dispose of the developer and fixer solutions by letting them into the sewer, 49.4% of them dilute the solutions and let them into sewer and only 5.6% return them to the supplier. About 40.6% of the dentists dispose of excess silver amalgam by throwing it into common bin. Conclusion. It was concluded that not all dentists were aware of the risks they were exposed to and only half of them observe infection control practices.

A Case of Cleidocranial Dysostosis: Dilemma for a Prosthodontist

Cleidocranial dysostosis (CCD) is an uncommon, generalized skeletal disorder characterized by delayed ossification of the skull, aplastic or hypoplastic clavicles, and complex dental abnormalities such as retention of multiple deciduous teeth, impaction or delayed eruption of permanent teeth and presence of supernumerary teeth. This case report describes a 30-year old male patient of CCD with classical findings and the challenges faced in his prosthodontic rehabilitation. Conventional complete dentures following interim complete dentures therapy had to be given as all other treatment modalities were ruled out because of anatomic limitations. Despite the disadvantages of removable dentures the patient adapted admirably to them with significant improvement in self-esteem. Though orthodontic and surgical correction may be the treatment of choice, the need to preserve the alveolar ridge could make fabrication of removable dentures in such patients, a viable option.

Cerrobend shielding stents for buccal carcinoma patients

Buccal carcinoma is one of the most common oral malignant neoplasms, especially in the South Asian region. Radiotherapy, which plays a significant role in the treatment of this carcinoma, has severe adverse effects. Different types of prosthesis may be constructed to protect healthy tissues from the adverse effects of treatment and concentrate radiation in the region of the tumor mass. However, the technique for fabrication of shielding stent with Lipowitzs alloy (cerrobend/Woods alloy) has not been well documented. This article describes detailed technique for fabrication of such a stent for unilateral buccal carcinoma patients to spare the unaffected oral cavity from potential harmful effects associated with radiotherapy.

A pilot study to evaluate the efficacy of cerrobend shielding stents in preventing adverse radiotherapeutic effects in buccal carcinoma patients.

BACKGROUND Radiation stents made of Lipowitz metal or cerrobend alloy are commonly used to shield uninvolved tissues from electron beams used in therapeutic radiation treatment of head and neck cancers. However, studies investigating the efficacy of cerrobend shielding stent in patients with unilateral buccal carcinoma remain rare. PURPOSE To evaluate the efficacy of cerrobend shielding stents in minimizing the potential adverse effects of radiation on oral tissues in buccal carcinoma patients. MATERIALS AND METHODS Twenty.eight participants were selected for the study based on predetermined inclusion criteria, out of which four participants were lost to follow-.up. Half of the remaining participants. (N = 12) were randomly given cerrobend shielding stent and the remaining 12 formed the control group. The effects of radiotherapy were evaluated by using Radiation Therapy Oncology Group. (RTOG) 0435 Head and Neck adverse effects grading tool. All participants were evaluated for xerostomia, mucositis, dysphagia, salivary changes, dysguesia, pain, trismus and radiation caries at baseline and 1 and 3. months post.radiotherapy. RESULTS All adverse effects were higher in control compared to study group, with post therapy difference for pain in swallowing, salivary changes, mucositis, dysphagia, dry mouth and caries being statistically significant. CONCLUSIONS Cerrobend alloy can be used effectively as shielding stent to reduce the adverse effects associated with external beam radiation therapy in unilateral buccal carcinoma patients.

Maxillary canine transposition – A literature review with case report

Tooth transposition is of several types and their classification depends on the teeth involved. The review of literature aims to discuss the incidence and identifying factors related to occurrence of this dental anomaly. The present study aims to discuss about the prosthetic treatment of a patient with unilateral maxillary canine - lateral incisor transposition with the absence of permanent lateral incisor.

Prosthetic rehabilitation of amputated hallux after distraction osteogenesis: one-year follow-up

Background: The great toe helps in maintaining body balance during standing, walking, running, dancing, and so on. Case Description and Methods: A 22 year-old female patient reported to the department, one month after losing her left hallux in a road accident. Anatomical reconstruction was performed with distraction osteogenesis. The prosthesis was constructed using a wax pattern of the normal hallux to create a silicone prosthesis. The residual limb mold was altered to increase prosthesis retention. Findings and Outcomes: The procedure was economical, conserved materials, and produced lifelike anatomy without requiring artistic expertise. Conclusion: Distraction osteogenesis helped in improving function and retention of the prosthesis. Satisfactory esthetic and functional results were observed at the one-year follow-up. Clinical relevance Distraction osteogenesis of the amputated hallux improved prosthetic prognosis by aiding retention. Modifications were made in the conventional prosthesis fabrication technique to increase retention, as the hallux is in constant movement and/or friction.

Efficacy of Acacia arabica gum as an adjunct to scaling and root planing in the treatment of chronic periodontitis: A randomized controlled clinical trial

Aim The aim of the present study was to explore the adjunctive use of Acacia arabica gel in the treatment of chronic periodontitis. Methods Single centre, randomised, triple blind, controlled trial on mild to moderate chronic periodontitis patients; Group I (SRP + Acacia arabica, n = 40) and Group II (SRP + placebo, n = 40); were analysed for clinical improvements in periodontal pocket depth (PPD) and clinical attachment levels (CAL) at baseline, 15 and 90 days on application of gels. Gingival index and plaque index were assessed as secondary parameters. Results Statistically significant PPD reduction (p < .05) and CAL gain (p < .05) was observed with use of Acacia arabica gel. The reduction in sites with moderate PPD was observed more among Group I than Group II and the difference was statistically significant (p = .001). Secondary outcome variables; Plaque Index and Gingival Index showed better resolution with Acacia arabica gel. Conclusion Acacia arabica leads to better clinical outcomes in patients with mild to moderate chronic periodontitis with effective antiplaque and anti-gingivitis action. It may be recommended adjunct to SRP for maintenance in patients with mild to moderate chronic periodontitis.
