A rare case of recurring calcifying epithelial odontogenic cyst in the maxillary sinus: a case report and literature review.

Calcifying epithelial odontogenic cyst (CEOC) is an odontogenic cyst with epithelial lining. CEOC is a rare entity that occurs in a wide age range, does not show any gender predilection, and accounts for only 1% of all jaw cysts. The lesion generally occurs in the region anterior to maxillary and mandibular molars and either intraosseously or extraosseusly. This entity might present as a cystic or solid lesion. Enucleation is the recommended treatment for a simple, unicystic CEOC. A case of recurring CEOC in the right maxilla antrum is presented here. The patient presented to the authors after postsurgical recurrence. The case was evaluated thoroughly, and the cyst was resolved.

Comparison of Mechanical Properties, Physical Properties, and Biocompatibility of Four Different Denture Base Resins: An In vitro Study.

Four new dental replacement base tars were evaluated in vitro to determine their mechanical qualities, authentic properties, and biocompatibility. Materials and Methods: In this experiment, we employed SR Triplet HOT (a fiber-developed heat fix tar), Sunflex (a multipurpose force fix sap), Trevalon-Hello (a high-impact heat fix tar), DPI (a digital pigment imaging system), and a variety of other pigments and inks (normal power fix tar). For these models, the ISO specification 1567 for dental substitute base gums called for testing of flexural strength, hardness, impact strength, water sorption and dissolvability, and cytotoxicity. Results: All the strength and mechanical properties tested had a statistically significant difference when intergroup analysis was performed. Conclusion: The exceptional physical and mechanical capabilities of the Sunflex denture base resin, together with its biocompatibility with oral tissues, make it a good candidate for use as a denture base material in routine clinical practice.

Influence of the Type of Topical Fluoride Delivery at Various Restoration Time Points on the Micro-Shear Bond Strength of a Resin-Based Composite on Bleached Tooth Enamel.

Background This study aimed to evaluate the micro-shear bond strength (mSBS) of an adhesive applied to bleached enamel to determine the effects of fluoride supply and restoration time on the mSBS. Methodology In this study, we bleached 130 samples of enamel and split them into the following three groups of 40 each: group MI: McInnes bleaching solution; group MIF: McInnes bleaching solution + topical acidulated phosphate fluoride gel; group FMI: 2% fluoridated McInnes bleaching solution. Non-bleaching or fluoridation was performed on a group of 10. Subgroups were created for each group (except for the control) to be restored for seven, 14, or 21 days. The mSBS test was performed on a universal testing machine after Tygon tubes were filled with composite resin and put on enamel surfaces. Tukey's post-hoc test (p = 0.05) and two-way analysis of variance were employed to analyze the data. Results The mSBS values obtained for all groups immediately and after seven days were lower, while at 14 and 21 days were similar to the control group. According to the data, group FMI had greater mSBS levels than groups MI and MIF, both immediately and seven days later. Conclusions When in-office bleaching was employed, only the fluoride McInnes solution was successful in quickly correcting the adverse effects of low mSBS.

Correlation of awareness and practice of working postures with prevalence of musculoskeletal disorders among dental professionals.

Over the last 20 years, a great many innovations have been introduced that are designed to reduce laborious activities; however, an unexpected consequence of these developments is a trend toward a sedentary lifestyle and prolonged static postures that are accompanied by musculoskeletal disorders (MSDs). MSDs have become a major issue of concern because the afflictions can be severe enough to disable professional careers. Although clinical dentistry is a field with immense potential for MSDs, only a few studies have investigated this issue. The present study was carried out addressing prevalence and awareness level of MSDs among 500 dental professionals from Central India. Also, the interrelationship between practices of working postures with occurrence of pain in different body parts were assessed using a structured questionnaire format. The results were statistically significant, and indicated that the prevalence of MSDs is high and that there is a dire need to enhance awareness regarding correct working postures. This study encompassed all factors that can be addressed as causes for MSDs among dentists.

To Evaluate the Prevalence of Edentulousness, the Present Prosthetic Status, and the Need for Prosthetic Treatment in the Population of Garhwa, Jharkhand.

AIM: This study aimed to evaluate the prevalence of edentulousness, the present prosthetic status, and the need for prosthetic treatment in the population of Garhwa, Jharkhand. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted among the population of Garhwa, Jharkhand. The sample size included 460 subjects belonging to an age group of 25 years and above. Detailed case history and thorough dental examination was done and all the findings were recorded and compiled. Each subject was interrogated with the help of a predesigned closed ended questionnaire. RESULTS: A total of six patients were completely edentulous, while 55.04% of males and 42.80% of females were partially edentulous. All patients who were completely edentulous were denture wearer, while among partially edentulous patients, 6.31% of males and 3.15% of females had RPD and 13.68% and 6.31% of males and females, respectively, had FPD as prosthesis. Prosthetic status of females was better than males In a comparison of prosthetic status between male and female, out of 460 subjects, 195 subjects opted for prosthesis, in which 117 were male and 78 were female. CONCLUSION: Community-based oral health education programs should be conducted to improve patients' oral health knowledge. Educating patients regarding the limitations of prosthesis as mechanical substitutes for natural teeth must be a continuing process from the initial patient contact until adjustments are completed.

To explore and develop a model to maintain and build upon a dental clinic open for all in developing regions, with a primary focus on India.

AIM: To study a service model that enables a clinic to be open to all members of the community, irrespective of their ability to pay. METHODS: Sampling methodology was used to gather information in two phases, with the city of Indore as the target region. In the first phase, dental professionals were surveyed to gather the cost of the facility, land and equipment and the cost of sustaining the practice. In the second phase, the residents of Indore were surveyed to collect information regarding their oral health problems and their expenditure for the same. Assessing the current situation, the questions to answer are related to the issues of dental health care access problems and the resources required, human and financial. RESULTS: (1) People younger than 20 years of age form a large proportion (43%) of the population of the city and also a large proportion (54%) of people who visit dental clinics; (2) Dental caries are commonly found in the population younger than 20 years of age and mobile teeth in those older than 50 years of age; (3) Dental caries and mobile teeth are almost equally found in people of the age group 20-50 years old; (4) A significantly large proportion of those older than 50 years old have had all their teeth extracted; and (5) A significantly large proportion of the 20-30 years of age group has had no teeth extracted. CONCLUSION: The model which we propose works well for low income patients; however, it places a lot of extra burden on the higher income group. A lot of effort can be put into generating revenue from other sources, including events and donations.

Comparison of semilunar coronally repositioned flap with gingival massaging using an Ayurvedic product (irimedadi taila) in the treatment of class-I gingival recession: A clinical study.

AIM: To study the comparison in terms of root coverage the effect of gingival massaging using an ayurvedic product and semilunar coronally repositioned flap (SCRF) to assess the treatment outcomes in the management of Miller's class I gingival recessions over a-6 mo period. METHODS: The present study comprised of total of 90 sites of Miller's class-I gingival recessions in the maxillary anteriors, the sites were divided into three groups each comprising 30 sites, Group I-were treated by massaging using a Placebo (Ghee) Group II-were treated by massaging using an ayurvedic product (irimedadi taila). Group III-were treated by SCRF. Clinical parameters assessed included recession height, recession width, probing pocket depth, width of attached gingiva, clinical attachment level and thickness of keratinized tissue. Clinical recordings were performed at baseline and 6 mo later. The results were analyzed to determine improvements in the clinical parameters. The comparison was done using Wilcoxon signed rank test. The overall differences in the clinical improvements between the three groups was done using Kruskal-Wallis test. The probability value (P-value) of less than 0.01 was considered as statistically significant. RESULTS: Non-surgical periodontal therapy and gingival massaging improves facial gingival recessions and prevents further progression of mucogingival defects. Root coverage was achieved in both the experimental groups. The SCRF group proved to be superior in terms of all the clinical parameters. CONCLUSION: Root coverage is significantly better with semilunar coronally repositioned flap compared with the gingival massaging technique in the treatment of shallow maxillary Miller class I gingival recession defects.

Peripheral cemento-ossifying fibroma: A case report with review of literature.

Peripheral cemento-ossifying fibroma (PCOF) is a rare osteogenic neoplasm that ordinarily presents as an epulis-like growth. This is of a reactive rather than neoplastic nature and its pathogenesis is uncertain. PCOF predominantly affects adolescent and young adults with greatest prevalence around 28 years. We report here a rare clinical case of PCOF of the mandible, 1 cm mesiodistally and 1.5 cm occluso-gingivally in diameter, which caused difficulty in eating and speech, in a 42-year-old female patient. She was asymptomatic for 1 year and on follow-up for 6 mo post surgically showed gingival health and normal radioopacity of bone without any recurrence. Clinical, radiographic and histological characteristics are discussed and recommendations regarding differential diagnosis, treatment and follow up are provided. The controversial varied nomenclature and possible etiopathogenesis of PCOF are emphasized.
