ORAL HEALTHCARE MARKET SALES DOUBLED DURING 5 YEARS PAST
Market to grow up to 30.4 Billion by 2019 in Pakistan DT Pakistan Report
K
ARACHI - Oral care value sales grew by 14 per cent in current value terms to spike its sales to PKR21.2 billion in 2014. Moreover, oral care is likely to grow by a CAGR of 8pc at constant 2014 prices during the forecast period to reach sales of PKR30.4bn in 2019 The reason for its quick rise and attaining a high value is being attributed to huge investments made by multinational and local companies in television and billboard advertisements for creating oral hygiene awareness among consumers. Moreover, urban consumers have also played a significant role in the growth of oral care as they have more education and awareness about
oral hygiene. One of the reasons cited for the growth of oral care by 14pc in current value terms was that oral care companies have been continuously focusing on making doctors and dentists their brand ambassadors. Market research reported that the market expanded by a staggering 117% in the last 5 years. In addition to this, consumers have a vast variety of toothpaste in terms of price and benefits. Another salient feature of the briefing was that Colgate-Palmolive Ltd maintained its lead in oral care with a value share of 49pc in 2014-
2015 followed by Close-Up holding 10% and Sensodyne holding 7% of the market share. The market survey finding articulates that the oral healthcare market has vast potential in the Pakistani market.

“PM&DC grading puts private medical & dental colleges out of reach of a common man” increase annual tuition fees by seven per cent for the students getting admission to private medical and dental colleges, thus making it beyond the reach of a common man. These decisions were taken in the 139th session of the council held recently. In a public notice PMDC set mandatory grading requirements. They decided to categorize the recognized Medical & Dental Colleges as A & B. Medical Colleges who have made the list are the ones with 500 bedded own Teaching Hospital, latest treatment facility including MRI & CT Scan and a Nursing College. All others who lack the aforementioned facilities are placed in category B. The meeting also decided that to let category A Private Sector Medical and Dental colleges raise their fees to Rs. 700.000. As for the standalone Dental Colleges the ones with 60 bedded own teaching hospital have been graded as category A with liberty to increase the fee.

Introduction: Smile analysis and aesthetic design Dental facial aesthetics can be defined in three ways. Traditionally, dental and facial aesthetics have been defined in terms of macro- and micro-elements. Macro-aesthetics encompasses the interrelationships between the face, lips, gingiva, and teeth and the perception that these relationships are pleasing. Micro-aesthetics involves the aesthetics of an individual tooth and the perception that the colour and form are pleasing. Historically, accepted smile design concepts and smile parameters have helped to design aesthetic treatments. These specific measurements of form, colour, and tooth/aesthetic elements aid in transferring smile design information between the dentist, ceramist, and patient. Aesthetics in dentistry can encompass a broad area— known as the aesthetic zone1. Rufenacht delineated smile analysis into facial aesthetics, dentofacial aesthetics, and dental aesthetics, encompassing the macroand micro-elements described in the first definition above2. Further classification
Table I: Components of smile analysis and aesthetic design.
identifies five levels of aesthetics: facial, orofacial, oral, dentogingival, and dental (Table 1)1,3. Initiating smile analysis: Evaluating facial and orofacial aesthetics The smile analysis/design process begins at the macro level, examining the patient’s face first, progressing to an evaluation of the individual teeth, and finally moving to material selection considerations. Multiple photographic views (e.g., facial and sagittal) facilitate this analysis.
At the macro level, facial elements are evaluated for form and balance, with an emphasis on how they may be affected by dental treatment 3,4 . During the macroanalysis, the balance of the facial thirds is examined (Fig. 1). If something appears unbalanced in any one of those zones, the face and/or smile will appear unaesthetic. Such evaluations help determine the extent and type of treatment necessary to affect the aesthetic changes desired. Depending on the complexity and uniqueness of a given case, orthodontics could be considered when restorative treatment alone would not produce the desired results (Fig. 2), such as when facial height is an issue and the lower third is affected. In other cases—but not all— restorative treatment could alter the vertical
dimension of occlusion to open the bite and enhance aesthetics when a patient presents with relatively even facial thirds (Fig. 3). Evaluating oral aesthetics The dentolabial gingival relationship, which is considered oral aesthetics, has traditionally been the starting point for treatment planning. This process begins by determining the ideal maxillary incisal edge placement (Fig. 4). This is accomplished by understanding the incisal edge position relative to several different landmarks. The following questions can be used to determine the ideal incisal edge position: . Where in the face should the maxillary incisal edges be placed? . What is the proper tooth display, both statically and dynamically? . What is the proper intra- and inter- tooth relationship (e.g., length and size of teeth, arch form)? . Can the ideal position be achieved with restorative dentistry alone, or is orthodontics needed? In order to facilitate smile evaluation based on these landmarks, the rule of 4.2.2—which refers to the amount of maxillary central display when the lips are at rest, the amount of gingival tissue revealed, and the proximity of the incisal line to the lower lip—is helpful (Fig. 5). At a time when patients perceive fuller and brighter smiles as most aesthetic, 4mm of maxillary central incisor display while the lips are at rest maybe ideal2,5. In an aesthetic

Fig. 6: Gingival symmetry in relation to the central incisors, lateral incisors and canines is essential to aesthetics. Optimal aesthetics is achieved when the gingival line is relatively horizontal and symmetrical on both sides of the midline in relation to the central incisors and lateral incisors.—Fig. 7: The aesthetic ideal from the gingival scallop to the tip of the papilla is 4–5mm.—Figs. 8–10: Acceptable width-tolength ratios fall between 70 % and 85 %, with the ideal range between 80 % and 85 %.—Fig. 11: An acceptable starting point for central incisors is 11mm in length, with lateral incisors 1–2mm shorter than the central incisors, and canines 0.5–1mm shorter than the central incisors for an aesthetic smile display.—Fig. 12: The canines and other teeth distally located are visually perceived as occupying less space in an aesthetically pleasing smile.—Fig. 13: A general rule for achieving proportionate smile design is that lateral incisors should measure two-thirds of the central incisors and canines four-fifths of the lateral incisors.—Fig. 14: If feasible, the contact areas can be restoratively moved up to the root of the adjacent tooth.—Fig. 15: Photoshop provides an effective and inexpensive way to design a digital smile with proper patient input.

smile, seeing no more than 2mm of gingiva when the patient is fully smiling is ideal6. Finally, the incisal line should come very close to and almost touch the lower lip, being no more than 2mm away2. These guidelines are somewhat subjective and should be used as a starting point for determining proper incisal edge position. Dentogingival aesthetics Gingival margin placement and the scalloped shape, in particular, are well discussed in the literature. As gingival heights are measured, heights relative to the central incisor, lateral incisor, and canine in an up/down/up relationship are considered aesthetic (Fig. 6). However, this may create a false perception that the lateral gingival line is incisal to the central incisor. Rather, in most aesthetic tooth relationships, the gingival line of the four incisors is approximately the same line (Fig. 6), with the lateral incisor perhaps being slightly incisal.[7] The gingival line should be relatively parallel to the horizon for the
being most important. . The midline only should be moved restoratively up to the root of the adjacent tooth. If the midline is within 4mm of the centre of the face, it will be aesthetically pleasing. . The midline should be vertical when the head is in the postural rest position Evaluating dental aesthetics Part of evaluating dental aesthetics for smile design is choosing tooth shapes for patients based on their facial characteristics (e.g., long and dolichocephalic, or squarish and brachycephalic). When patients present with a longer face, a more rectangular tooth within the aesthetic range is appropriate. For someone with a square face, a tooth with an 80% width-to-length ratio would be more appropriate. The width-to-length ratio most often discussed in the literature is between 75% and 80%, but aesthetic smiles could demonstrate ratios between 70% and 75% or between 80% and 85% (Figs. 8–10)1.
proportions. Natural portions demonstrate a lateral incisor between 60% and 70% of the width of the central incisor, and this is larger than the golden proportion 11 . However, a rule guiding proportions is that the canine and all teeth distal should be perceived to occupy less visual space (Fig. 12). Another rule to help maintain proportions throughout the arch is 1-2-34-5; the lateral incisor is two-thirds of the central incisor and the canine is four-fifths of the lateral incisor, with some latitude within those paces (Fig. 13). Finally, contact areas can be moved restoratively up to the root of the adjacent tooth. Beyond that, orthodontics is required (Fig. 14). Creating a digital smile designed in Photoshop Although there are digital smile design services available to dentists for a fee, it is possible to use Photoshop CS5 software (Adobe Systems) to create and demonstrate for patients the proposed smile design treatments. It starts by creating tooth grids—
of the teeth (Fig. 15). This transparent layer will enable the image to be outlined without the work being embedded into the image. . Name the layer appropriately and, when prompted to identify your choice of fill, choose “no fill,” since the layer will be transparent, except for the tracing of the tooth grid. . To begin tracing the tooth grid, activate a selection tool, move to the tool palette, and select either the polygonal lasso tool or the magnetic lasso tool. In the authors’ opinion, the polygonal works best. Once activated, zoom in (Fig. 16) and trace the teeth with the lasso tool. . To create a pencil outline of the tooth, with the transparent layer active, click on the edit menu in the menu bar; in the edit drop-down menu, select “stroke”; choose black for colour, and select a twopixel stroke pencil line (Fig. 17), which will create a perfect tracing of your selection. Click “OK” to stroke the selection. Select (trace with the lasso selection tool) one tooth at

central incisors and the lateral incisors and symmetric on each side of the midline2,8. The gingival contours (i.e., gingival scallop) should follow a radiating arch similar to the incisal line. The gingival scallop shapes the teeth and should be between 4mm and 5mm (Fig. 7)9. Related to normal gingival form is midline placement. Although usually the first issue addressed in smile design, it is not as significant as tooth form, gingival form, tooth shape, or smile line. Several rules can be applied when considering modifying the midline to create an aesthetic smile design: . The midline only should be moved to establish an aesthetic intra- and inter-tooth relationship, with the two central incisors
The length of teeth also affects aesthetics. Maxillary central incisors average between 10mm and 11mm in length. According to Magne, the average length of an unworn maxillary central to the cementoenamel junction is slightly over 11mm 10 . The aesthetic zone for central incisor length, according to the authors, is between 10.5mm and 12mm, with 11mm being a good starting point. Lateral incisors are between 1mm and a maximum of 2mm shorter than the central incisors, with the canines slightly shorter than the central incisors by between 0.5mm and 1mm (Fig. 11). The inter-tooth relationship, or arch form, involves the golden proportion and position of tooth width. Although it is a good beginning, it does not reflect natural tooth
predesigned tooth templates in different width-tolength ratios (e.g., 75% central, 80% central) that can be incorporated into a custom smile design based on patient characteristics. You can create as many different tooth grids as you like with different tooth proportions in the aesthetic zone. Once completed, you will not have to do this step again, since you will save the created tooth grids and use them to create a new desired outline form for the desired teeth. Follow these recommended steps: . To begin creating a tooth grid, use a cheekretracted image of an attractive smile as a basis (e.g., one with a 75% width-to-length ratio). Open the image in Photoshop and create a new clear transparent layer on top
a time and then stroke it (Fig. 18). Select and stroke (trace) the teeth up to the second premolar (the first molar is acceptable; Fig. 19). . The image should be sized now for easy future use in a smile design. In the authors’ experience, it is best to adjust the size of the image to a height of 720 pixels (Fig. 20) by opening up the image size menu and selecting 720 pixels for the height. The width will adjust proportionately. . At this time, the tooth grid tracing can be saved, without the image of the teeth, by double-clicking on the layer of the tooth image. A dialog box reading “new layer” will appear; click “OK.” This process unlocks the layer of the teeth so it can be Continued on page 11

By highlighting the history of dentistry and oral hygiene across Asia through fun and interactive exhibits, the museum hopes to raise awareness in the country about the importance of proper oral care. The 620 m2 museum, which is sponsored by the royal family, features five main exhibits, each aimed at improving understanding of the importance of good dental health. "We want to ensure that Thais will have a healthy smile in our 'Land of Smiles' for as long as possible," Dr Phira Sithiamnuai, assistant professor and Deputy Dean for Collaboration and Networking at the faculty, told the Bangkok Post last week. "Our goal for the museum is to encourage Thai children to understand the
importance of oral health in an entertaining way. We hope that learning with fun will inspire people to make healthy choices about their oral health." A highlight for children is the giant model of a mouth. Assisted by the staff, visitors are encouraged to practise their toothbrushing skills on the huge teeth with equally giant toothbrushes. Other interactive items are a 3-D human model that shows how oral health can affect the overall well-being, as well as several multimedia displays on dental science. Furthermore, the exhibition takes a closer look at the history of dentistry throughout China, India and Thailand, including collections of dental materials and tools, as well as information on dental statistics, and even a prehistoric human skeleton that features traces of unnaturally modified teeth.

I Many Thais, especially people in remote areas, lack access to basic oral health care. As reported online by the Bangkok Post, Sithiamnuai remarked that the dentist per capita ratio in the capital is 14 times higher than in the north-east of the country, for example. According to figures from the Bureau of Dental Health, Thailand has just 11,607 dentists. This translates to a dentist-population ratio of approximately 1:5,533, compared with an average of 1:2,000 in most developed countries. The Sirindhorn Dental Museum is located at the HRH Princess Maha Chakri Sirindhorn 50th Anniversary Building at the university's Phayathai campus and is free of admission.
SLAMABAD - Higher Education Commission (HEC) in collaboration with the United States Agency for International Development (USAID) organised a twoday training session on 'Effective Financial Aid Offices for USAID' - both for merit and need-based scholarship programme. Over 35 representatives of the financial aid offices of 24 partner universities of the USAID attended the training, which was aimed at improving effectiveness and efficiency of these offices in various facets such as communication skills, coordination and interaction with aspiring students regarding scholarships and procedure involving execution of the programme. USAID Merit and Needs-Based Scholarship Programme (MNBSP) is a $37 million scholarship programme, offering graduate and undergraduate degrees in 31 public and private universities in Pakistan. Fifty per cent of scholarships are reserved for meritorious and deserving female students. Speaking at the concluding ceremony, HEC executive director Dr G Raza Bhatti highlighted local and overseas scholarship projects, faculty and infrastructure development Continued on page 13
Continued from page 05 removed. Drag the layer of the teeth to the trash, leaving only the layer with the tracing of the teeth (Fig. 21). In the file menu, click “save as” and choose “.png” or “.psd” (Photoshop) as the file type. This will preserve the transparency. You do not want to save it as a JPEG, since this would create a white background around the tracing. Name the file appropriately (e.g., 75% W/L central). . By tracing several patients’ teeth that have tooth size and proportion in the aesthetic zone and saving them, you can create a library of tooth grids to custom design new teeth for your patients who require smile designs. The Photoshop smile design technique The Photoshop Smile Design (PSD) technique can be done on any image, and images can be combined to show the full face or the lower third with lips on or lips off. This article demonstrates how to perform the technique on the cheek-retracted view. The first step in the PSD technique is to create a digital conversion of the actual tooth length and width, and then digitally determine the proposed new length and proportion of the teeth. Determining digital tooth size To determine digital tooth size, follow these steps: . Create a conversion factor by dividing the proposed length (developed from the smile analysis) by the existing length of the tooth. . The patient’s tooth can be measured in the mouth or on the cast (Fig. 22). If the length measures 8.5mm but needs to be at 11 mm for an aesthetic smile, divide 11 by 8.5. The conversion factor equals 1.29, a 29% digital increase lengthwise. . Open the full-arch cheek-retracted view in Photoshop, and zoom in on the central incisor. Select the eyedropper palette. A new menu will appear. Select the ruler tool (Fig. 23).
. Click and drag the ruler tool from the top to the bottom of the tooth to generate a vertical number, in this case 170 pixels (Fig. 24). Multiply the number of pixels by the conversion factor. In this case, 170 x 1.29 = 219 pixels; 219 pixels is digitally equivalent to 11 mm (Fig. 25). Determine the digital tooth width using the same formula. . Create a new layer, leave it transparent, and mark the measurement with the pencil tool (Fig. 26). Applying a new proposed tooth form Next, follow these steps: . After performing the smile analysis and digital measurements, choose a custom tooth grid appropriate for the patient. Select a tooth grid based on the width-to-length ratio of the planned teeth (e.g., 80/70/90 or 80/65/80). Open the image of the chosen tooth grid in Photoshop and drag the grid on to the image of teeth to be smile designed (Fig. 27). . If the shape or length is deemed inappropriate, press the command button (control button for PCs) and “z” to delete and select a suitable choice. . Depending on the original image size, the tooth grid may be proportionally too big or too small. To enlarge or shrink the tooth grid created (with the layer activated), press command (or control) and “t” to bring up the free transform function. While holding the shift key (holding the shift key allows you to transform the object proportionally), click and drag a corner left or right to expand or contract the custom tooth grid. . Adjust the size of the grid so that the outlines of the central incisors have the new proposed length. Move the grid as necessary using the move tool so that the incisal edge of the tooth grid lines up with the new proposed length (Fig. 28). . Areas of the grid can be individually altered using the liquify tool (Fig. 29). Digitally creating new aesthetic teeth Next, follow these suggested steps:
. With the new tooth grid layer and the magic wand tool both activated, click on each tooth to select all of the teeth in the grid (Fig. 30). . Expand the selection by two pixels in the expand menu; click “select > modify > expand” (Fig. 31). Note that the selection better approximates the grid. You can expand the selection or contract as necessary using the same menu. Activate the layer of the teeth (cheekretracted view) by clicking on it (Fig. 32). . Next, activate the liquify filter (you will see a red mask around the shapes of the proposed teeth). The mask creates a digital limit that the teeth cannot be altered beyond. This is similar to creating a mask with tape for painting a shape (Fig. 33). . Use the forward warp tool by clicking on an area of the existing tooth and dragging to mold/shape the tooth into the shape of the new proposed outline form (Fig. 34). Repeat this for each tooth. If you make a mistake or do not like something, click command (or control) and “z” to go back to the previous edit (Fig. 35). Adjusting tooth brightness The following steps are recommended next: . Select the whitening tool (dodge tool) to brighten the teeth. In the dodge tool palate, click on “midtones” and set the exposure to approximately 20%. Click on the areas of the tooth you want brightened (Figs. 36 & 37). . Alternatively, with the teeth selected, you can use the brightness adjustment in the brightness/contrast menu; click “image > adjustments > brightness/ contrast”. Performing the changes on only one side of the mouth allows the patient to compare the new smile design to his/her original teeth before agreeing to treatment. Create a copy To save the information you have created for presentation to the patient, follow these tips:
. Go to “file” and select “save as.” . When the menu appears, click on the “copy” box. . Name the file at that step. Save it as a JPEG file type. . Designate where you want it saved. . Click “save.” A file of the current state of the image will be created in the designated area. You can now continue working on the image and save again at any point you want. Conclusion Knowledge of smile design, coupled with new and innovative dental technologies, allows dentists to diagnose, plan, create, and deliver aesthetically pleasing new smiles. Simultaneously, digital dentistry is enabling dentists to provide what patients demand: quick, comfortable, and predictable dental restorations that satisfy their aesthetic needs.

Market to grow up to 30.4 Billion.... Continued from front page Advancement in Dental Studies & Research (IADSR) said that the rise in oral health care awareness in Pakistan due to FMCG and toothpaste & tooth brush manufactures is no more than 10% - 15%. He further commented that the rise in GNP in Pakistan along with Education and international exposure of a common individual in Pakistan are the major reasons for rise in Oral care awareness. He said that it is a known and established phenomena globally that the rise oral health care awareness is directly proportional to the Secondary and Tertiary education in any country. He said that marketing campaign executed by the toothpaste manufactures and marketers have surely raised the awareness on brushing habits however, the rise of oral health care awareness cannot be complimented alone to the advertising activities. Students to pay more after PM&DC.... Continued from front page directed the colleges to implement the new fees from 2015-16 sessions onwards. This will affect more than 6000 students across Pakistan but who cares. "No medical and dental institution training for MBBS/BDS in the private sector shall charge tuition fee more than 600,000 per annum per student," the 2013 regulations read. Interestingly one of the oldest private dental college in Sindh which until recently was marked in red with admissions stopped has now been graded as category A. Sources told Dental News that the letter issued to them by PM&DC has also been retracted stating that it was sent inadvertently. With this decision it is expected that the tuition fees to the tune of Rs100,000will be increased per student for category 'A' private colleges. Similarly, category 'B' colleges would charge each student Rs42,000 as incremental annual tuition fees.
Students reacted to the development with anger and shock, in a recent statement by the Pakistan Medical Student Council (PMSC) they referred to PM&DC as "private medical and dental council". PM&DC is silent on payments other than tuition fee like students pay university examination fees, taxes, hostel fees, transport fees and the onetime admission fee under the PM&DC regulations. Some private colleges are charging Rs 200,000 as non-refundable admission fees and there is no stopping. PM&DC Registrar has categorically said that the council had increased the tuition fees to facilitate those medical and dental colleges which showed good performance. It seems no Public sector medical or dental college came upto the standards of PM&DC as none of them were rewarded. 24 partner varsities attend training session Continued from page 10 conducted by the HEC. He appreciated support from the US government and partner universities in promoting higher education in Pakistan and emphasized that focal persons attending the training must implement the techniques and tools for efficient functioning of the financial aid offices. USAID Education Office's deputy director Dr Garth Willis was also present at the event. Speaking on the occasion, he said that this training is a useful activity to create better understanding of the programme's objectives among partner universities so that it can be implemented according to the criteria of merit and need. He said that the US government has invested in many education projects in Pakistan and USAID-Merit and Need-based Scholarship Programme is one of its key programmes which is dedicated to cater to the needs of talented students who, due to financial barriers, are deprived of higher education. Later, Dr Willis and Dr Bhatti gave away certificates among representatives of the financial-aid offices.
PLAGIARISM AT UNIVERSITIES
SHC Suspends HEC notification DT Pakistan Report
H
YDERABAD - The Sindh High Court has recently suspended the implementation of an earlier notification from the Higher Education Commission, which had blacklisted the former Vice president of the Federation of All Pakistan Universities Academic Staff Association, on charges of Plagiarism. According to recent media reports; Dr Azhar Ali Shah- an associate professor in Sindh University, was among the 20
teachers of seven universities in Pakistan who were blacklisted and stripped of all benefits and allowances in March 2015. The news report further stated that; All of them were charged with plagiarism and were accused of re-publishing, in Pakistani journals, two of his articles that were earlier published in foreign journals, without modifying his research. The act amounts to selfplagiarism in the academic parlance. The court restrained the SU's
syndicate, which was scheduled to meet in the end of August, from implementing the HEC's notification until the next hearing. The petitioner informed the court that; decision over the issue is on the meeting's agenda. In his petition before the Hyderabad Circuit Bench, Shah maintained that; this decision by the HEC's Plagiarism Standing Committee violated the commission's plagiarism policy. He was not even heard before
facing the HEC's action, he added. Shah claimed that before publishing his articles in the SU's Research Journal in 2011, the varsity's focal person for antiplagiarism - Dr M Saleem Chandio had cleared it for publication. He argued that; the committee took action on a fake complaint against him. "The [then] acting SU's VC Dr Parveen Shah who is
VC in Khairpur's Shah Abdul Latif University (SALU)] and former SALU professor Ghulam Raza Bhatti [one of the 13-member Plagiarism Standing Committee] used their influence [against me]," he had said in his initial reaction to his blacklisting. Shah hoped the court would declare the notification illegal and order the HEC to restore his benefits.
