Objective: The study investigated the experience of orofacial pain (OFP) symptoms and associated disability and psychosocial impact in community dwelling and institutionalized elderly people in Hong Kong. Methods: A community-based cross-sectional survey involving elders aged 60 years and above. Participants were recruited at social centres for the elderly and homes for the aged throughout Hong Kong. Elders who reported OFP symptoms in the previous four weeks took part. Standard questions were asked about OFP conditions in the previous month and the Manchester Orofacial Pain Disability Scale (MOPDS), the Oral Health Impact Profile (OHIP-14) and the General Health Questionnaire (GHQ-12) were administered. The MOPDS was translated and validated for use in Chinese elders. Results: 200 community dwelling and 200 institutionalized elders participated. Toothache was the most common symptom (62.0%) and burning sensation in the tongue was least common (0.5%). The distribution of pain symptoms, pain duration and severity and pain ratings were similar in both groups. The MOPDS (Chinese elders version) had good reliability and construct validity. The MOPDS and OHIP-14 summary scores was significantly higher in the institutionalized elderly (p<0.001 and p<0.013, respectively). Psychological distress (GHQ-12 score ≥4) was more common among the institutionalized elderly (11%) than the community dwelling elderly (4.0%, p=0.002). Conclusions: Orofacial pain symptoms were associated with significant disability and had a detrimental impact on psychological distress level and quality of life, particularly in the institutionalized elderly. There is a need to improve access to professional care and health-related outreach services generally for elderly people in Hong Kong. © BASCD 2012.

2-D electrical resistivity tomography (ERT) is one of the geophysical methods applied in subsurface study for engineering purposes. The ERT result was correlated with 2 boreholes to identify the subsurface characteristic. The study location situated at PT 8088 and 8089, Rawang, Selangor, Malaysia with coordinate of 3° 15' 37.2" N and 101° 38' 48.22" . Four ERT survey lines were conducted at the study area with Pole-dipole array with 5m minimum electrode spacing, 5mA and 20mA of minimum and maximum d.c. current respectively. The ERT results show the study area consists of two main zones, alluvium with resistivity value of 10-800 Ωm, and granite bedrock with resistivity value of >2500 Ωm with depth 5-70m. Saturated zone and hard layer were detected with resistivity value of <110 Ωm and 1500-2500 Ωm respectively which indication of fractured zone. Borehole record, BH3 and BH5 show the overburden was alluvium (gravels with sand) and depth to granite bedrock was 25.5m and 12.0m respectively. © 2011 ejge.

Manihot allemii M. J. Silva is described and illustrated as a new species, and its morphological affinities and conservation status is discussed. It is most similar to M. salicifolia Pohl in having a subshrubby and erect habit and in the general aspect of its unlobed leaves, but differs from it in having leaves that are conspicuously petiolate, an inflorescence that is a congested spike-like thyrse, entire and diminute bracts and bracteoles subtending flowers of both sexes, pistillate calyx that is deeply lobed with oblong lobes, and staminate flowers with 8 or 10 stamens. Both species belong to a group of 14 species recognized by their possession of entire and unlobed leaves, which are the subject of taxonomic studies by the second author. Some notes on the leaf anatomy of species of Manihot that have entire and unlobed leaves are also presented. © 2016 The Authors.

Dry retraction cords help to displace the gingiva and also to absorb the gingival crevicular fluid and saliva to maintain a dry field. When used along with medicaments whether these medicaments help to improve the absorption of fluid or affect the fluid absorption by decreasing the efficiency of the retraction cord is unknown.The aim of the study was to know the effect of various medicaments on the fluid absorbency of the retraction cords and also, to know whether the thickness of the retraction cords influences its fluid absorbency.A total of 90 samples of 5cm length retraction cords were taken. Cords were divided into 30 samples for each cord thickness of 0, 1 and 2. Of these 30 samples, 10 samples were used to measure dry weight (Group I), 10 samples were immersed in 15.5% ferric sulfate (Group II) and remaining 10 samples were immersed in 10% aluminium chloride (Group III) for a period of 20 minutes. The excess medicament was removed by blotting paper. Initial weight was recorded. Following this, five cords from each group were immersed in plasma solution and remaining in artificial saliva for 10 minutes. Then these were taken out and measured. The amount of the fluid absorbed was determined by subtracting the weight before fluid immersion (weight after immersion in test medicament) from the weight after fluid immersion (weight after immersion in plasma or artificial saliva). The study was analyzed through one-way ANOVA and Bonferroni post-hoc comparisons for pair wise differences.When immersed in medicaments, there is a significant difference in absorption of fluids (artificial saliva and plasma) between the untreated dry cord and cord treated with 15.5% ferric sulfate (p<0.05). But, there was no significant difference in fluid absorption between the dry untreated cord and cord treated with 10% aluminum chloride and between cords treated with 15.5% ferric sulfate and 10% aluminum chloride.Ferric sulfate (15.5%) is a better medicament for absorption of fluid.

The present study was undertaken to compare two methods of obturation in primary teeth by using lentulospirals and pressure syringe, radiographically.Sixty teeth in subjects with mean age of 5.88 1.58 years were obturated randomly using two different obturating techniques, i.e. group I: Thirty teeth obturated with pressure syringe, and group II: Thirty teeth obturated with lentulospiral. Quality of obturation and presence or absence of voids were assessed by taking radiographs after obturation was done using both the techniques. RESULTS of quality of obturation were statistically analyzed using Chi-square test and Mann-Whitneys test, whereas voids were analyzed using Chi-square test.No statistically significant difference between the quality of obturation using pressure syringe or lentulospiral (p > 0.05) was observed. However, significantly higher number of voids were found for lentulospiral technique as compared to pressure syringe (p < 0.01).Both the techniques were found to be equally efficient statistically, though lentulospiral produced more voids.

In oral diagnostics there is a great challenge to determine biomarkers for screening and evaluating the disease activity. Biomarkers can also serve as a useful tool to measure the efficacy of the therapy.To evaluate and compare the levels of salivary calcium, phosphorous, alkaline phosphatase and pH levels in periodontally healthy subjects and patients with gingivitis and periodontitis.The present study consisted of 150 subjects aged between 20-45 years who were divided into three groups; periodontally healthy, gingivitis and chronic periodontitis. Prior to the clinical examination the demographic details, relevant information of the subject, gingival index, plaque index, Oral Hygiene Index (OHI) and pH were recorded. Biochemical assay of saliva i.e., inorganic calcium, phosphorous and alkaline phosphatase were estimated by colorimetric method. ANOVA and Tukeys test were applied for statistical analysis.The mean levels of biomarkers studied were; inorganic calcium (12.55g/dl), phosphorous (14.50g/dl), alkaline phosphatase (49.62g/dl) and pH (11.65). There was a gradual increase in these levels as the condition progressed from health to gingivitis or periodontitis which was statistically significant at p<0.001.Based on these results, it can be concluded that, the biomarkers like salivary calcium, phosphorous, alkaline phosphatase and pH can be considered for evaluating the diagnosis and prognosis of periodontal tissues in disease and health.

Natal teeth are teeth present in the oral cavity at the time of birth. It is extremely rare to find natal teeth in association with pathological conditions of the oral cavity. Pyogenic granuloma is a type of inflammatory hyperplasia that appears as an over exuberant connective tissue response to a stimulus or injury, in the present case the injurious agent is the natal tooth. The parents of the eight day old male infant brought the child with a natal tooth associated with a soft tissue lesion growing from the gum pad. A provisional diagnosis of pyogenic granuloma was made on behalf of the clinical findings which were confirmed by histopathology. The natal tooth was extracted and the lesion was surgically excised. Complete healing of the gumpad took place after excision of the lesion and extraction of the natal tooth and the child was able to feed normally within a week. The purpose of this case report is that Pediatric Dentist should be aware of this rare unusual clinical presentation and plan for an appropriate treatment modality in order to avoid any future complications.

Incisional hernia usually contains intra peritoneal organs as its content. Extra peritoneal structures like bladder as a content of incisional hernia are relatively uncommon. We managed a young male with an incisional hernia containing a large bladder diverticulum as its content. The bladder diverticulum was going up to the base of scrotum along the posterolateral surface of penile corpora. The patient was diagnosed pre operatively with radiological investigations and underwent exploration with release of diverticulum from corpora and pubic arch followed by diverticulectomy and herniorraphy. To the best of our knowledge and available literature search, there isnt any similar reported case.
