Objective:
To document knowledge, attitudes and practices (KAP), of PMDC registered local dental practition-ers (DPs) regarding some aspects of complete dentures (CDs) occlusal relations.
Methodology:
DPs (N= 100) responded to 13 aspects of CD occlusion in a pre-structured data sheet. Statement / questions were; DP experiences of patients reliability for detecting occlusal errors, reasons for the lack of intercus-pation between teeth in mouth, clinical methods for detecting occlusal errors, common presentations of soft tissue trauma due to occlusal errors, effect, on denture in mouth, of the discrepancy between maximal intercuspal position (MIP) and retruded contact position (RCP) and acceptable range of the discrepancy from RCP to MIP. There were also statements relating to the most ideal CD occlusal relations and desired tooth contact types, identification of functional cusps, procedure for correcting premature occlusal contacts, identification of clinical situations requiring balanced ar-ticulation and remounting of CDs having occlusal errors.
RESULTS:
DPs (N=72/100) responded. Upto 30% practice time of 67 (93%) DPs, was devoted to CDs services with only upto 20 CDs/yr made by 69 (95.7%) DPs. Instructions to laboratory were given by 62 (86.1%) DPs. DPs (N=57, 79.1%) had never participated in training or workshop on CDs. DPs (N=51, 70.8%) knew premature contacts in RCP prevent intercuspation. Oral corns on ridge underneath CDs as consequence of occlusal interferences (OIs) was known to 30 (41.6%) DPs. Slide ranging from 0.5 to 1.0 mm from RCP to MIP was acceptable to 45 (62.5%) DPs. Majority 63 (87.5%) felt bilateral occlusal contacts important. Adjustment by spot grinding premature occlusal contacts in RCP was considered by 60, (83.3%) DPs.
Conclusion:
DPs had inappropriate KAP about some aspects of CD Occlusion. Need for relevant instructions, demonstrations and practical exposure of dental students and of the need for continuing educational programs for ex-isting DPs is emphasized.

OBJECTIVE:
To assess the frequency of musculoskeletal disorders among dental professionals working at a tertiary care dental institute.
METHODOLOGY:
A descriptive study was carried out at Armed forces institute of Dentistry between March 2011 to May 2011. All the doctors working in AFID were included in the study. Questionaire were administered to the doctors. It included questions about demographic information and questions regarding musculoskeletal pain disorders and their frequencies. The relationship between musculoskeletal disorders, working hours, and frequency of MSK disorders were assessed by using chi-square test. Value of p <0.005 was considered statistically significant.SPSS Version 15 was used to analyze the study.
RESULT:
Thirty five dentists filled the questionnaires. Twenty one were males and 14 females. Most of the dentists(97.1%) had experienced some form of musculoskeletal pain in the last 12 months. Twenty seven (77.1 %) had experienced MSK pain in the last seven days. Average number of days off work was 2.77 days per year. Frequency of different MSK pains in last twelve months was neck pain 28.6%(10), shoulder pain 28.6% (10), lower back 25.7% (9), wrist 11.4%(4) and knee 5.7% (2). Restriction from activities was experienced by 60 % of the dentists in the last 12 months.
CONCLUSION:
Musculoskeletal disorders are very common among dental professionals. It mainly involves the neck, shoulder, back and wrists. The probable associations are prolonged working hours, abnormal postures for extended period of time and lack of ergonomic awareness.

OBJECTIVE:
Objective of the present study was to find the presence of H. pylori bacteria in the plaque samples of complete dentures in patients with dyspepsia. Settings: A descriptive diagnostic study was carried out in the Department of Prosthodontics, (name of study setting removed by the editor) from January 2007 to December 2009.
METHODOLOGY:
A total of 67 complete denture patients with clinical symptoms of dyspepsia with their ages ranging from 50 to 65 years were included in the study. Specimens of denture plaque and gastric biopsy were collected from all the patients. The denture plaque specimen was processed by Rapid Urease Test (RUT) and gastric biopsy samples were processed for RUT and also for the histopathology.
RESULT:
The males and female distribution of the 67 patients was 46 (68.65%) and 21 (31.34%) respectively with their mean age as 57.5 (SD= 10.6 years). Using the rapid urease test (RUT), some 59 (88.05%) patients showed presence of H. pylori in denture plaque specimens as compared to 46 (68.65%) who were positive for H. pylori from the gastric biopsy samples. The histopathologically studied specimens of gastric biopsy showed H. pylori in 55 (82.1%) patients while 12 (17.9%) patients showed chronic active gastritis which was not associated with H. pylori.
CONCLUSION:
Denture plaque and oral cavity may serve as a temporary source for H. pylori in patients with gastritis. Antibiotic treatment of H. pylori along with meticulous denture hygiene measures may possibly prevent potential hazards. However, the beneficial effect of this needs to be confirmed.

OBJECTIVE:
The aim of the study was to investigate transverse and sagittal dental effects of rapid palatal expansion in different age groups and malocclusions.
METHODOLOGY:
A total of 46 patients were selected for rapid palatal expansion (RPE). The inter-canine (CC) and inter-Molar (MM) width were measured in millimeters pre- and post-treatment on study models. Furthermore, the maxillary arch depth line (MADL) was also measured on the study casts.
RESULT:
There were 22 males and 24 females in this study undergoing rapid palatal expansion (RPE) with a mean age of 13.2 years. The patients were divided into 4 age groups namely A (9-10 years), B (11-12 years), C (12-13 years) and D (14-15 years) respectively. In our study sample 15 patients had skeletal class I, 11 had skeletal class II and 20 had skeletal class III malocclusions, respectively, as confirmed by the patients pre-treatment cephalometric radiograph measurement. Females showed a mean percentage MM value of 52.6% post treatment while males showed a mean percentage MM value of 46.8% respectively. Both sexes reported decreasing MADL values with age with Group D (14-15 years) showing 16.7% in males and 15.7% in females. Males in class I and class III malocclusion showed the highest RPE post treatment mean MM values of 51.7% and 46.2%, while females demonstrated 44.2% in class one and 48.2% mean MM values in class II malocclusions.
CONCLUSION:
Both sexes showed CC and MM changes after expansion, however females showed less MADL changes post-treatment. Furthermore, MADL values decreased with age in both males and females. RPE in class I and class II cases showed greater MM changes in males, while in females class I and class III malocclusions showed more changes followed by class II malocclusions. Further studies are necessary to determine long-term stability of dental changes post-retention.

OBJECTIVE:
Instrumentation is a key part of root canal therapy which allows disinfection, placement of medication and filling of the root canal system. Over the years several instruments have been developed for root canal. The aim of this study was to compare the outcome of endodontic treatment performed with Protaper and K3 rotary systems.
METHODOLOGY:
A Randomized control trial was performed at the Operative dentistry department of Altamash Institute of Dental Medicine, Karachi. A total of 249 patients were selected from the outpatient department and were randomly allocated to two treatment groups using random allocation table. After obtaining written consent, root canal treatment in group 1 was performed with Protaper rotary instruments; whereas, in group 2, treatment was performed with K3 rotary instruments. Outcome of the treatment (success or failure) was evaluated after 6-months by using Periapical Index (PAI).
RESULT:
Fourteen out of 249 patients did not attend the follow up so they were excluded from the final analysis. Out of 235 patients, treatment outcome of 198 (84.3%) patients was successful. In Protaper rotary group, 97 (82.2%) patients had successful treatment outcome while in K3 group, 101 (86.3%) patients showed successful outcome. On the basis of PAI score, no statistically significant difference in the treatment outcome was observed between the two rotary groups.
CONCLUSION:
No significant difference in the outcome of endodontic treatment performed with either Protaper or K3 rotary systems was noticed.

Oral health is defined as a standard of the oral and related tissues which enables an individual to eat, speak and socialize without active disease, discomfort or embarrassment and which contributes to general well-being. The traditional biomedical approach towards oral as well as general health is now being considered inappropriate to meet the health challenges of a population. A basic knowledge and application of social determinants of health is necessary at every level of a country’s healthcare system, so that effective preventive and efficient treatment strategies can be adopted by the various stakeholders in the healthcare system in order to meet those challenges.
This review article presents a synopsis of the oral health challenges faced by the Pakistani population in the light of the determinants of health and gives a critical appraisal of the current as well as possible future public health approaches to overcome these challenges. It is aimed to contribute towards the existing knowledge about the public health aspects of oral health for medical and dental students, professionals and policy makers.
