In Indonesia Gynura procumbens (Lour) Merr leaves have been long used as various cancers medication. Many in vitro and in vivo studies have demonstrated anticarcinogenesis of ethanol extract of Gynura procumbens leaves. The aim of this study was to investigate the anticarcinogenesis of the ethanol extract of Gynura procumbens leaves on 4 nitroquinoline 1-oxide (4NQO)-induced rat tongue carcinogenesis. Fifty six 4 week old male Sprague Dawley rats were used in this study and divided into 7 groups. Group 1, 2 and 3 were lingually induced by 4NQO for 8 weeks. In groups 2 and 3 the extract was given simultaneously with or after 4NQO induction finished, each for 10 weeks and 26 weeks, respectively. Groups 4, 5 and 6 were induced by 4NQO for 16 weeks. However, in groups 5 and 6 the extract was given as well simultaneously with or after the 4NQO induction, each for 18 weeks, respectively. Group 7 served as the as untreated control group. The results from microscopical assessment showed that tongue squamous cell carcinomas (SCC) developed in 100% (3/3) of group 1. However, only 33.3% (2/6) and 25% (2/8) of rats in groups 2 and 3, respectively demonstrated tongue SCC. Among groups 4, 5 and 6, no significant difference of tongue SCC incidence was observed. From these results it is apparent that the ethanol extract of Gynura procumbens leaves could inhibit the progression of 4NQOinduced rat tongue carcinogenesis in the initiation phase.

Curettage is used in periodontics to scrap off the gingival wall of a periodontal pocket, and is needed to reduce loss of attachment (LOA) by developing new connective tissue attachment in patients with periodontitis. The purpose of this study was to evaluate the success of curettage by the formation of tissue attachment. This clinical experiment was done by comparing LOA before curettage, 2 weeks and 3 weeks after curettage on 30 teeth with the indication of curettage. Study population were periodontitis patient who attending dental clinic at Hospital University Science Malaysia (HUSM) with inclusion criteria good general health condition, 18 to 55 years old male or female and presented with pocket depth > 3mm. The teeth were thoroughly scaling before intervention and evaluated by measuring the periodontal attachment before curettage, two weeks and three weeks after curettage. Repeated measure ANOVA and Paired T Test were used to analyze the data. The result of the study showed that there was reduction in the periodontal attachment loss in periodontitis patient after curettage either in the anterior or posterior teeth which were supported by statistical analysis. This study concluded that curettage could make reattachment of the tissue

The function of copper (Cu) inside amalgam is to increase hardness and impact force and to decrease thermal expansion coefficient. In general, amalgam which is used in dentistry and available in the market is contain Cu 22%, while the maximum Cu concentration is 30%. It is necessary to determine the concentration Cu does generate the best physical properties to be used as dental restorative agent. Amalgam is made by mixing blended-metal Ag-Sn-Cu (with Cu concentration of 13%, 21%, 22%, and 29%) and Hg, stirred manually in a bowl for 15 minutes,leave it in temperature 27°C for 24 hours to become hardened. The result of X-Ray Diffractometer (XRD), analyzed by Rietveld method and Rietica program, shows amalgam with Cu 29% concentration for Cu3Sn compound density is 31.790 sma/Å3, for Ag2Hg3 compound is 41.733 sma/ Å3, a Cu3Sn relative weight percentage of 43.23%, Ag2Hg3 of 54.54%, Cu 7Hg6 of 2.23% and hardness of Cu 29% is 90.700 ± 0.005 kgf/mm2. These numbers are the highest values on Cu 29% concentrations compared to other copper concentration variants. Whereas amalgam thermal expansion coefficient on Cu 29% is (2.17 ± 0.91)10-3 mm/°C is the lowest value compared to other Cu concentration. The conclution is that adding Cu concentration into amalgam will increase density value, Cu3Sn relative weight percentage, hardness level and will decrease amalgam thermal expansion coefficient. Amalgam 29% Cu concentration has better physical properties compared to amalgam Cu 22% concentration.

Dental plaque is the primary etiological factor in periodontal diseases. However, there are many factors that can modify how an individual periodontal tissue will respond to the accumulation of dental plaque. Among such risk factors, there is increasing evidence that smoking tobacco products alters the expression and rate of progression of periodontal diseases. The aim of this study was to find out the loss of periodontal tissue adhesion in smokers by measuring pocket depth using probe, and by measuring alveolar bone damage using Bone Loss Score (BLS) radiographic methods on teeth 12, 11, 21, 22, 32, 31, 41, 42. Based on T Test statistical analysis, there were significant differences in pocket depth damage of alveolar bone in smokers and non smokers. In conclusion there were increasing pocket depth and alveolar bone damage in smokers.

Bond strength between 2-Hydroxyethyl methacrylate HEMA-based dentin bonding agent and dentin collagen had proved by presence of the chemical interaction. This union involved the carbonyl group on HEMA resin with amino group on dentin collagen following produce an amide chain. However, this bond strength influence by humidity condition of dentin collagen and HEMA resin. The aim of this study is to measure the effect of humidity on peak value of the HEMA carbonyl absorbance band. The bond strength between by HEMA bonding agent and dentine collagen was analyzed in different humidity, e.g. in 60%, 70%, 80%, and 90% humidity. Control experiment was done in ambient room humidity that is 65%. Chemical bond that formed between HEMA and dentine collagen was carried out by mixing pure HEMA with bovine type-I collagen which had been stored in different humidity. The esther carbonyl group of HEMA will react with the amino group of collagen, produced an amide bonding, which is observed by measuring the IR spectrum absorbance of the esther carbonyl group of HEMA in KBr method. The decrease of the carbonyl group absorbance indicates the more chemical bonds formed. By measuring the absorbance of C=O esther in different humidity, it showed that the greatest number of chemical bonds resulted when the experiment was done in 70% humidity condition.

Asthma is commonly related to allergic diseases, nevertheless only 40% of asthma patients are related to allergy or atopy. There are some unknown etiologies of asthma that are still in researches. One of the possible causes of asthma is the multiple chemical sensitivity syndrome (MCS) which related to the “neurogenic switching hypothesis”. Since rhinitis, sinusitis and asthma are closely related, treatments which are successfully reduce or eliminate the rhinitis and sinusitis symptoms should also be advantageous to asthma management. There were a lot of sinusitis treatments which reduced asthma symptoms such as nasal corticosteroid, diathermy and surgery. It was also been reported that oral focal infection might cause sinusitis. However, the involvement of oral focal infection in the etiopathogenesis of asthma was seldom discussed. The objective of this study is to propose a mechanism of the relationship between oral focal infection and asthma which is explained by the “neurogenic switching hypothesis”. Two asthmatic patients who also had periodontal disease, pulpal and periapical infection were treated with conventional and/or surgical dental treatments. After the dental and periodontal treatments were completed, the usual triggers of severe asthma attacks such as cold and house dust did not elicit the asthma symptoms. It concluded that regarding to the disappearing of asthma symptoms, the elimination of oral focal infection had a beneficial effect in reducing asthma symptoms.

Numerous researches on pulp tissue changes caused by orthodontic forces have been performed, among others are: pulp angiogenesis, pulp tissue respiration rate, alkaline phosphatase and aspartate aminotransferase enzyme activities; micro vascular response inside the pulp and the effect of dental movement i.e. extrusion, intrusion, and torque. The result is still controversial, as some researchers claim that orthodontic force has a negative effect, others deny by saying there is no such effect on pulp tissue.
