The long-term success of implants depends upon the degree of osseointegration that can be achieved, which is largely determined by the volume and quality of bone available at the time of surgery. Bone height and volume is often diminished in patients due to the extended time after tooth loss and this is a major limitation impacting long term dental implant treatment success. Some

of the commonly used surgical techniques for ridge augmentation are (i) Osteoperiosteal flap (OPF); (ii) Distraction osteogenesis (DO); (iii) Block grafting; (iv) Guided bone regeneration (GBR) using membranes; and (v) Subperiosteal tunneling for minimally invasive approach to GBR. This talk discusses the development of bioceramic graft materials with controlled microstructure and superior biological properties to those currently available. Dicalcium phosphate cements, brushite and monetite, resorb faster than

hydroxyapatite (HA). Monetite (unlike brushite) does not re-precipitate as HA in vivo, and demonstrates superior osteoconductive properties. We have produced monetite disc grafts by varying processing conditions which alter their physical properties such as porosity, surface area and mechanical strength. Histological observations after 12 weeks of onlay grafting on rabbit calvaria reveal higher bone volume (38%) in autoclaved monetite grafts in comparison with the dry heat prepared monetite grafts (26%). The vertical bone height gained is similar for both the types of monetite grafts (up to 3.2 mm). This talk discusses and provides information regarding two types of monetite onlay grafts prepared with different physical properties that could be used for achieving more predictable vertical bone augmentation.

Early Childhood Caries (ECC) has been documented to be of highest

prevalence in predominantly Coloured (Mixed-Race) rather than in White- or Black-dominated communities of South Africa. As a result of a new realization that parents/primary caregivers (PCGs) rather than the child are the key individuals who determine the social and behavioural environment that shape oral health practices for children, this study set out to examine the relationship between health behaviours of primary caregivers (Biological parents or not) of preschool children and caries experience in South Africa's Ekurhuleni Health District (using a predominantly Coloured community of Arla Park). A total of 545 PCG-child pairs for children in the age group of 12-71 months were interviewed (PCGs only) and examined, using DMFT/deft indices (PCGs and children). Results showed that overall, the mean deft ranged between 2.88 (aged <4 years) and 3.78 (aged 4-5.11 years); and high deft scores occurred to children with PCGs who are unemployed (78.1%),consume alcohol frequently (59.87%), visited dentist only when in pain and for tooth extraction (68.11%) and admitted to putting infants to sleep with bottle-with-sugary-drinks (65.72%). The strong negative relationship that was revealed in this study between socio-economic profile, oral/dental care and health seeking/child grooming behaviour of PCGs on the one hand, and mean deft index of their children on the other, can be a useful tool for screening and targeting child populations in need of treatment, and also assist public policy planning towards developing health preventative and promotion programmes to aid early intervention and prevention.

Aim: The aim of this systematic review was to compare the clinical performance of anterior single-retainer all-ceramic and metal fused to porcelain resin-bonded fixed partial dentures (RBFPDs) after an observation period of at least 1 year.

 

Materials & Methods: An electronic PubMed search complemented by manual searching was conducted to identify prospective cohort clinical studies with a mean observation period of at least 1 year. Data extraction and study inclusion were performed independently by 2 reviewers. The studies included reported survival rates of 2-unit anterior all-ceramic and metal-ceramic cantilever

RBFPDs. Patients had to be examined at follow-up visit. Survival rates were analysed and descriptive comparisons performed.

 

Results: The search resulted in 9 prospective cohort studies. Survival rates ranged from 90 -100% over a mean observation period of 55.4 months for all-ceramic RBFPDs and 93 -100% over a mean observation period of 35.2 months for metal-ceramic RBFPDs. Debonding was the most frequent complication with more occurrences in all-ceramic RBFPDs.However, no observed difference in survival rates was determined between the two types of restorations.

 

Conclusion: Both types of resin-bonded FPDs provide an effective short to medium term treatment option. All-ceramic singleretainer RBFPDs was shown to have excellent survival rates and esthetic outcome when replacing anterior missing teeth. Dentists should be aware of success rates, longevity and failure modes of this type of restoration and recommend it to patients as a medium to long-term option.

The purpose of this in vitro study is to evaluate and compare the cytotoxicity of three commercially available root-ending materials,MTA Plus, Pro root MTA and Retro MTA, at different storage times after mixing on human periodontal fibroblast using a MTT method. Varied concentrations (3, 6, 12, 25, 50 mg/ml) of the fresh and set root-ending materials (ProRoot MTA, MTA Plus and Retro MTA) were placed in adjacent flasks of human periodontal fibroblast in DMEM medium within 96-well plates. Cellular viability was evaluated using a MTT assay after 24, 48, and 72 h of initial mixing. The results were analyzed with 1-way ANOVA. The results showed that there was no significant difference between the biocompatibility of MTA Plus, and that of Pro root MTA or Retro

MTA (P>0.05). Furthermore, no significant difference was observed between different time intervals for each group (P>0.05). The current in vitro study showed almost similar biocompatibility for ProRoot MTA and MTA Plus and Retro MTA.

Introduction: Microorganisms have been identified as the main culprits of oro-dental diseases. With the advent of photodynamic therapy, a new minimally invasive and precise approach towards disinfection has been developed. Photodynamic therapy means light induced athermal inactivation of cells and microorganisms. The principle of photodynamic therapy is that, by using a photosensitizer,the microorganisms are first stained, then sensitized and destroyed after irradiation with light of suitable wavelength and energy density.

 

Case Series: In this case series, antimicrobial photodynamic therapy was used for periodontal pocket therapy, root canal disinfection,treatment of alveolar osteitis, management of peri-implantitis and disinfection after caries excavation in pediatric patients. In all conditions, it was found to be effective in eradicating pathogenic bacteria and controlling inflammation.

 

Conclusion: Antimicrobial photodynamic therapy successfully stops inflammation without antibiotics, without surgical intervention and without any adverse effects with maximum therapeutic benefits in different oro-dental infections. Future directions should conduct researches involving new photosensitive compounds seeking improved photophysical and photochemical properties to maximize the photodynamic action in the biological environment.

Introduction: The anterior middle superior alveolar (AMSA) field block was discovered during the development of computercontrolled local anaesthetic delivery (CCLAD) system. It is known to anaesthetize ipsi-lateral palatal and buccal, hard and soft tissues, with a single injection and can be administered with ease using CCLAD system. This study was conducted to determine the

extent of maxillary anaesthesia achieved with AMSA field block given with CCLAD system during periodontal surgery.

 

Materials & Methods: 44 subjects indicated for periodontal flap surgery of either of the maxillary quadrants were enrolled for the study. Anaesthesia was provided with a single AMSA injection with a CCLAD system. Subjective and objective signs of local anaesthesia were assessed 15 minutes after the injection. Extent of anaesthesia was observed for palatal and buccal, hard and soft tissues both before and after the periodontal surgery.

 

Results: The results revealed that the palatal hard and soft tissues were significantly highly anesthetised (p=0.001) as compared to the buccal hard and soft tissues. Anterior to the first molar, palatal anaesthesia was significantly more as compared to posterior to the first molar in both hard (p=0.001) and soft tissues (p=0.04).

 

Conclusion: The AMSA field block is highly effective in anaesthetizing the ipsi-lateral palatal hard and soft tissues. A single injection is sufficient to numb the palatal tissues, anterior to first molar, to carry out periodontal surgery, in the maxilla.

Cosmetic dentistry is considered as one of the priorities that people need all around the world in a high percentage. According to that, cosmetic dentistry is considered the subject of today. Based on this fact, the term cosmetic dentistry has become vernacular across the globe. Most of the patients nowadays are looking for cosmetic corrections. They may ask to rehabilitate their smile so that they can get the most beautiful smile according to their convenience. The reason behind this patient demand may have great effect on the psychological behavior of the patient. The variation of this demand depends on the severity of the appearing beauty of the smile line of the patient. Many of these patients may become shy; others may become aggressive with psychological trauma. Also

some of these patients may isolate themselves from the community so, they may not share any social activities and the end result is inferior complexity. So the clinician here is playing the role of a dentist and a psychiatrist at the same time. Hence, the dentist or the specialist who is working in the field of cosmetic dentistry may change the whole life of the patient. In other words, you are

rehabilitating the life of your patient. The difficulties in cosmetic correction may vary from one case to another depending on many factors. The most important target of all these cases is bad looking smile line which affects the personality behavior. These factors may include 1. The severity in complicated cases, like severe crowding, which may need huge space availability, 2. Difficulties to treat cases like gum smile profile patient, 3. Difficulties to treat patients lacking the required inter occlusal space relationship, 4.Difficulty to treat patients having big diastema spaces, 5. Difficulties to treat canine cases out of occlusion which might be situated labially, 6. Difficulty to treat patients with severe bone loss in the anterior region, 7. Difficulty to treat patients with inconvenience in the level of gingival margin, 8. Difficulties to treat patients with shifted midline that is clearly visualized and diagnosed, and 9.Difficulty to treat patients having traumatic accidents that require immediate solution to improve the aesthetic profile. This article discusses these difficulties by displaying some clinical case reports of many patients suffering from bad smile line. Most of these patients have psychological trauma and they were looking for immediate solution. Meanwhile, they were looking for a dentist with deep emotion that he has a spiritual behavior towards them. This is considered part of the keys for successful end results. The final conclusion of this article is how to make your patients live happy and practice their life normally keeping in the mind that money is not everything in our faded life.

Using computer aided methods, a final object can be manufactured either by milling from a block or additive manufacturing which allows standard object production with low cost and decreased manufacturing time. The aim of the study was to compare the internal and marginal fit of crowns fabricated using conventional casting, laser sintering and soft-metal milling. A first maxillary

molar die made of metal was fabricated. Metal substructures with standardized sizes were manufactured using conventional casting,laser sintering and soft-metal milling (N=15/group). Internal-fit and marginal-fit of metal substructures were evaluated. The metal substructures were seated on the metal die using light body silicone material. Excess silicone was cleaned. Following the setting,

crowns were removed and silicone was weighed to evaluate the 3D internal cement gap. Same specimens were used for marginal gap measurements under a light microscope. Statistical analysis was performed using one-way ANOVA followed by Tukey HSD test (α=.05). A statistically significant difference was observed for both internal and marginal fit among compared groups (p<0.05). The highest mean silicone weight (standard error) was observed in casting group (36.8±1.9 mg) followed by laser sintering (26.6±1.5mg) and soft-metal milling (20.7±1.4 mg) groups. The lowest mean marginal gap (standard error) was observed in laser sintering group (4.2±1.2 μm) followed by casting (8.7±1.2 μm) and soft-metal milling (22.3±1.2 μm) groups. Although statistically significant differences were observed among all compared groups, a clinically significant difference can’t be mentioned.

Fungal infections have become major causes of morbidity and mortality among immuno-compromised patients. Oral candidiasis is a fungal infection caused the opportunistic pathogen named Candida albicans. Conventional available treatments for oral candidiasis include topical antifungal azoles such as Miconazole, Amphotericin B and Nystatin. Miconazole, in various formulations

(gels, lozenges or mixtures) for local application, is an effective antimycotic drug for treating oral candidiasis. However the increase of resistant micro-organisms to conventional treatment is becoming a challenge, researchers are trying to identify potential drugs and alternatives treatments with better and improved therapeutic effects and fewer adverse effects. Essential oils have been used for the treatment of several diseases. They possess antibacterial,antifungal, antiviral and antiseptic activities. Certain essential oils have been shown to have antifungal activity or reduce the risk of fungal infections. In this study, a selection of essential oils was made and evaluated based on their anti-candidal activity, organoleptic properties, availability and minimum inhibitory concentration for possible inclusion and formulation into the chewing gum as an active pharmaceutical ingredient. Preformulation studies were conducted to identify suitable excipients and evaluate physicochemical compatibilities of the actives with selected excipients. From three placebo formulations obtained from the gum base manufacturer, preliminary development of the formulation was done. A series of formulations were developed by varying different tablet components. The active pharmaceutical ingredients (API’s) were included in the gum core both at 2% (w/w) of the MCG composition. The formula was subjected to scale-up. Produced MCG’s from the scale-up were film coated to improve stability. Finished products were subjected to post-compression evaluation including in vitro release of the API’s from the dosage form. This study proved that it is possible to develop a medicated chewing gum with a

combination of essential oils as active substances for the effective treatment of oral candidiasis.
