ABSTRACT
Objective: The purpose of this prospective, randomized, double‑blind study was to compare the anestheticefficacy of 2% mepivacaine and 2% lidocaine (both with 1:80,000 epinephrine) for inferior alveolar nerve blockin mesioangular bilaterally impacted third molar extraction. Study Design: Forty patients with mesioangular bilaterally impacted third molars were taken for the study; either 2% mepivacaine or 2% lidocaine is given in a double‑blind manner. Surgery started 5 min after solution deposition. Success was defined as no or mild discomfort (visual analog scale [VAS] recordings) during the surgical procedure. Results: The mean time for onset period 4.2 min and 4.6 min (P = 0.018). The mean duration anesthesia 177.17 min 166.71 min (P = 0.085). No significant difference between the scores of pain reported by the patients by VAS and venovenous bypass
treated with mepivacaine and lidocaine (P = 0.000). Slight increased postoperative analgesics required for mepivacaine group (4.000 tablets) and lidocaine group (4.170 tablets) (P = 0.335). The sharp increase of pulse rate with respect to both the solutions at 5 min after postinjection of local anesthetics. However, there was no statically significant difference in systolic and diastolic blood (P = 0.681) and (P = 0.270). Conclusion: Lidocaine and mepivacaine with the same vasoconstrictor have similar action and both solutions are effective in surgical procedures. There were also no significant differences between them in relation to the intensity of postoperative pain.

ABSTRACT Epidemiological studies have shown strong evidence that periodontal disease does not affect all subjects in the same manner. Objective: There are subjects and sites with higher risk for disease progression. This study tested parameters to select "a priori" sites and subjects potentially at risk. Materials and Methods: The data from periodontal clinical examinations of 2273 subjects was used. The clinical loss of attachment was measured in 6 sites per tooth. Using computer software, the patients were distributed into 14 age groups, with intervals of 5 years, from 11 years to greater than 75 years of age. The measure of each site was compared with the average and the median values of the subject age group, with the results indicating site comparative severity (SCS). Three global parameters were calculated: parameter 1 (PI) - percentage of sites with clinical attachment loss > 4 mm; parameter 2 (P2) - percentage of sites with clinical attachment loss j> 7 mm; parameter 3 (P3) - percentage of sites with clinical attachment loss surpassing the median value for the age group by 100% or more. Results: There were 1466 (65%) females and 807 (35%) males. Most subjects had PI, P2 and P3 values less than 30%. Parameter 3 allowed a division of the sample similar to that of Parameters 1 and 2, with the advantage of analyzing the subject in relation to his/her age group. It was suggested that the methodology of SCS is useful for selecting a population with a high disease prevalence, and that cut-off lines between 10% and 20% would be appropriate for using parameter.

Abstract Introduction: Demirjian’s dental maturity scores are widely used to assess dental maturity andestimate age. Various authors revised Demirjian’s method by adapting Demirjian’s stages andproposed new data for age estimation. The present study aimed to assess the age using original and modified Demirjian methods from the reference data and also to correlate dental age with
chronological age.

Materials and methods: In the target sample of 660 dental radiographs of age 6-16.99 years, seven mandibular permanent teeth (Central incisor I1 to Second molar M2) were assessed and dental age was calculated using four maturity scales and ten methods that use data for individual teeth. The mean difference between dental age (DA) and chronological age (CA) was calculated as well as other measures of accuracy such as mean obsolute difference (MAD), percentage aged to within six months and to within 10% of age.

Results: The method that performed best was the dental maturity scale of Willems I et al .(highest percentage of individual aged to within 0.5 years of real age) with MAD of 1 year, followed by Original Demirjian method with MAD of 1.06 years and Willems II method with MAD of 1.1 years.

Conclusion: The present study showed that original Demirjian’s method was found to be
highly accurate followed by Willems I method. Thirdly, Willems II method was better followed
by Chaillet et al. method. All the fourteen methods assessed were found to reliable for age
estimation in South Indians.

 Abstract The anterior ridge defects present in a patient are very difficult to treat and they require great amount of planning, like removable or fixed prosthesis and options of implant. Here is a article that describes the process of fabrication of Andrew’s bridge to treat a Class III anterior ridge defect using natural teeth as abutments for its fixed component followed by a removable component. The procedure of fabricating Andrew’s bridge was undertaken when a 26 years old patient came to the department of prosthodontia after being operated for the cleft lip and palate. After the patient was treated with this Andrew’s bar system, it was evaluated over a long period of time and accordingly it was concluded that the patient had a good adaptability, comfort, pleasing esthetics and phonetics were achieved as desired and can be given in patients where esthetics due to repositioning of teeth creates difficulties.

ABSTRACT Facial tissue loss presents with multiple functional and psychological problems. Its rehabilitation can improve the physical, mental and social well being of the patient. In conditions where surgical corrections are not favourable, the prosthetic approach to rehabilitate the missing structures can solve the problems, with added advantages of having complete control over colour and morphological outcome to match the surrounding skin and the counter lateral part. This case report describes the rehabilitation of a patient with the right auricular defect who was treated with a silicon auricular prosthesis and few ornaments were used as the retentive aids.

Abstract. To evaluate and compare the shear bond strength of three composite restorative materials.30 extracted human maxillary pre molars were selected for the study. The teeth were divided into 3 groups of 10 each. Group A-poly acid modified composite, Group B-Hybrid composite, Group C-Nano filled composite was used. Composite post was built on the bonded surfaces of teeth. The teeth were subjected to thermo cycling for 1000 cycles between 60 c to 660 c.The teeth were then mounted on universal testing machine and fractured under a shearing load applied at the speed of 0.1 mm/min. The readings were noted, tabulated and shear bond strength calculated in Mega Pascal (Mpa) units.There was significant difference in the mean shear bond strength of the three tooth colored restorative materials. Shear strength values were in the range of to Mpa. Nano filled composite gave the highest mean of shear bond strength where as polyacid modified composite showed the lowest value of shear strength. Based on the results of the study, it can be concluded that contemporary Nano filled composite materials gave better results than other materials.

Keywords: Nano filled composite, hybrid composite, shear bond strength

Aims and Objectives: Considerable importance to oral health care was lacking in India, and oral health neglect continues to exist, which is evident in the low utilization rates and poor oral health status. Conventional dentures are the most common alternative in restoration of lost teeth. Without proper denture care practices, there is an increased risk of developing a multitude of problems. The aim of this study is to assess the denture care practices among complete denture wearers in East Godavari district, Andhra Pradesh.
 Materials and Methods: A cross‑sectional study was conducted in the department of Prosthodontics at the Konaseema Institute of Dental Sciences, Amalapuram, Andhra Pradesh. Patients with self‑care ability and adequate overall health who were using either single or full complete dentures for more than 6 months from the time of the study were requested to participate in the study. A total of 375 study participants were given a self‑administered questionnaire on denture care practices followed by clinical examination of the denture status. Statistical analysis was done using the Statistical Package for the Social Sciences software for windows, version 20.0 (Armonk, NY: IBM Corp).
Results: The majority of participants reported cleansing their dentures once a day, with brush and water, and had the habit of removing the dentures at night. Almost 80% of the participants reported their denture status to be good/fair. Clinical examination revealed that slightly more than half of the participants had poor denture status. Conclusion: This study highlights the need for improvement in patient education and counseling with respect to the maintenance of dentures and upkeep of denture hygiene. It also emphasizes the need for educating patients on how to evaluate the status of their dentures.
