ABSTRACT
AIM: The aim of the study was to correlate the pH and fluoride ion uptake with surface hardness of composite resin based restorative materials after topical fluoride application. METHODOLOGY: Forty disks of each of test materials Composite (Filtek Z350XT, 3M ESPE, St Paul, MN, USA), Resin modified glass ionomer (Vitremer) and Compomer (Dyract AP) were made and ten disks of each material were placed in different test solutions - 1.23% APF gel, Sodium fluoride mouth rinse, 0.9% neutral fluoride and distilled water (Control group). After 36 hours of immersion, specimens were subjected to microhardness testing machine for evaluation of surface hardness. RESULTS: The greater hardness deterioration for all materials resulted with 1.23% APF gel when compared to the control group. Composite (Filtek Z350XT, 3M ESPE, St Paul, MN, USA) showed 17.13 VHN (control group 59.11 VHN). Vitremer showed 9.71 VHN (control group 37.71 VHN). Compomer showed 19.22 VHN (control group 36.78 VHN). CONCLUSION: 1.23% ApF gel significantly decreased hardness of composite, Vitremer and Compomer. Hardness deterioration associated with sodium fluoride mouth rinse and 0.9% neutral fluoride was less compared to 1.23% ApF gel.

BACKGROUND: This paper investigates the relationship betweendifferent types of impactions with postoperativeinflammatory tissue reaction. MATERIALS & METHODS: Consecutive patients with only mandibular third molar impactions were included in our study. They were classified by winter's classification. The disimpactions were performed under local anaesthesia. Time for surgery was noted for each surgical procedure. Postoperative inflammatory complication in terms of pain, swelling and trismus were noted. RESULTS: 150 male patients in the age groupof 18-40 years were studied. Inflammatory tissue reactions were increasing with more operative time. Distoangular and Horizontal impactions were associated with more pain on first 3 days of surgery along with more swelling and trismus. Vertically impacted teeth were associated with least complications. CONCLUSION: Post operative morbidity was increasing along with moreoperating time and increase in the depth of mandibular third molar impaction.

ABSTRACT
BACKGROUND: Mobile Dental Van (MDV) removes the barrier of accessibility and improves the care of underserved populations. Dental institutions across India, providing postgraduate training in dental public health organize and conduct MDV programs as part of their curriculum. AIM: To describe the structure, conduct and utilization of MDV programs in consideration to duration of use by the academic institutions for oral health care delivery in rural areas. METHODS: Hundred postgraduates in Public Health Dentistry representing 27 dental institutions of India completed a 40 item questionnaire on MDV program and utilization. Descriptive statistics and Fisher's exact test were used for statistical analysis. RESULTS: The mobile dental van programs were more curative with limited orientation towards preventive services. The institutionally sponsored programs with experience of more than 10 years had better organized setup and adequate emergency management system together with electricity, water and storage facilities. Chair side assistants were employed in 90 percent of newer programs compared to only 50 percent of older programs. Dental hygienists were helping the dentists in only 60 percent of programs. CONCLUSIONS: The utilization of MDV in treating rural underserved is indispensable, but revenue and high productivity is difficult to achieve as lower socioeconomic patients are predominantly served. MDV programs operational in postgraduate institutions have to improvise on correcting the shortcomings regarding the facilities and manpower to improve the utilization of the programs.
