|5. |TITLE OF THE TOPIC |“CHEILOSCOPY – A STUDY OF LIP PRINTS AS AN AID FOR SEX |

| | |IDENTIFICATION.” |

| | | |

| | | |

| | |

|6 |BRIEF RESUME OF THE INTENDED WORK: |

| | |

| |6.1 Need for the study: |

| |Establishing a person’s identity is a very important process in civil and criminal cases. Finger prints, postmortem reports and |

| |DNA comparisons are probably the most common techniques allowing fast and secure identification processes.1 Theory of uniqueness|

| |is the scientific principle behind finger print analysis to convince the court of law. Likewise, studies done so far show that |

| |even lip prints are unique for an individual and hence have the potential for personal identification. 2 |

| | |

| |The external surface of lips has many elevations and depressions forming a characteristic pattern called lip prints, examination|

| |of which is known as cheiloscopy. 3 |

| |Studies done previously showed that patterns remain unchanged over a person’s lifetime. 4 |

| | |

| |The prime objective of present study is to ascertain whether the lip prints behold the potential for identification of sex of an|

| |individual and to determine the most common lip patterns in relation to a specific gender. |

| | |

| |6.2 Review of Literature: |

| |Aggrawal A in 2004, in his forensic files had analysed the importance of lip prints and reported that fissures and criss-cross |

| |lines are different in different people and can form a very good basis of identification.5 |

| |Utsuno. H et al in 2004, had conducted a preliminary study of post mortem personal identification of lip prints and confirmed |

| |that post mortem lip prints taken from human remains, which are subjected to physical and chemical changes can be used similarly|

| |as living persons.6 |

| |Sonal V and Nayak.C.D in 2005, had conducted a study of lip prints of different individuals and concluded that sex of a person |

| |can be determined by the lip print pattern.3 |

| |T R Saraswathi, Mishra G and Ranganathan K in 2009, aimed to study the lip print pattern of different individuals in different |

| |parts of the lip and to find out the incidence of any particular pattern in a given age group and concluded that intersecting |

| |pattern was common and reticular pattern was least common.4 |

| |In 2009,Sharma P, Saxena S and Rathod V conducted a study on lip print patterns and concluded that lip prints are unique for a |

| |person and they also help in determining the sex of a person.7 |

| |In 2010, Domaity,et al did a study on morphological patterns of lip prints of individuals in Saudi Arabia and confirmed that the|

| |lip print pattern is unique for each individual even in twins and family relatives.8 |

| |Sforza C,et al in 2010 conducted a study on age and sex related changes in three dimensional lip morphology and concluded that |

| |the dimensions of lips and mouth are sexually dimorphic and are modified by aging process.9 |

| | |

| |6.3 OBJECTIVES OF THE STUDY: |

| |To determine the sex of an individual using lip print. |

| |To evaluate the predominant lip print pattern in either sex |

| | |

| |MATERIALS AND METHODS : |

| | |

| |7.1 Source of data: |

| |This study will be conducted on 120 individuals, 60 males and 60 females between 18-40 years reporting to the department of oral|

| |medicine and radiology, Sri Hasanamba Dental College and Hospital. |

| | |

| |Materials used: Dark colored lip stick, Cellophane tape, White chart paper and Magnifying lens. |

| | |

| |7.2 Method of collection of data: |

| |The data will be obtained from those subjects satisfying the criteria’s , as listed below. |

| | |

| |INCLUSION CRITERIA: |

| |Age range: 18-40 years |

| |Subjects with absolute normal transition zone between the mucosa and the skin. |

| |Lips free from any pathology. |

| | |

| | |

| |EXCLUSION CRITERIA: |

| |Subjects with any malformation, deformity of lips. |

| |Subjects with any trauma or scar on the lips. |

| |Subjects with any active or passive lesions on the lip. |

| |Individuals with known hypersensitivity to lip sticks. |

| | |

| |PROCEDURE: |

| |All the participants will be given a brief about the purpose of the study and written consent will be taken from the subjects |

| |before undertaking the study. |

| | |

| |Lips of all the subjects will be cleaned and the dark colored lip stick will be applied with a single stroke evenly on the lips.|

| |The subjects will be asked to rub both the lips to evenly spread the applied lip stick. Over the lip stick, the glued portion of|

| |cellophane tape strip will be placed and the subject will be asked to make a lip impression in the normal rest position of the |

| |lips by dabbing in the center first and then pressing it uniformly towards the corner of the lips. |

| | |

| |The cellophane strip will be stuck to the white chart paper for permanent record purpose and then visualized by magnifying lens.|

| |The lip prints obtained will be coded, while noting the name and sex of the respective individuals. The lip prints will be given|

|7. |to an independent examiner for analysis who is not aware of the subjects. The middle part of the lower lip (10 mm wide) will be |

| |taken as area of study in accordance with Sharma et al7, since this part of the lip is almost always visible in any trace. The |

| |number of lines and furrows present, their length, branching and combinations will be noted. |

| | |

| |In this study we will follow the classification of pattern of the lines on the lips proposed by Suzuki and Tsuchihashi,7 |

| |Type I : Clear- cut vertical grooves that run across the entire lips. |

| |Type Il : Similar to type I, but do not cover the entire lip. |

| |Type 2 : Branched grooves |

| |Type 3 : Criss-cross pattern or reticular grooves |

| |Type 4 : Undetermined, grooves do not fall into any of the types and cannot be differentiated morphologically. |

| | |

| |The sex of the individual shall be determined as per the descriptions given by Vahanwala et al 3. |

| | |

| |Type 1 & 1l pattern dominant : Female |

| |Type 2 pattern dominant : Female |

| |Type 3 pattern dominant : Male |

| |Type 4 pattern dominant : Male |

| | |

| |All the lip prints obtained will be studied and interpreted by the examiner to identify the sex of the subjects and results will|

| |be analyzed for the presence or absence of common lip print patterns in males and females. |

| | |

| |Statistical Analysis : |

| |Data will be collected and statistically analyzed. |

| | |

| |7.3. Does the study require any investigations or interventions to be conducted on patients or other humans or animals? If so |

| |please describe briefly. |

| | |

| |YES |

| | |

| |7.4 Has ethical clearance been obtained from your institution in case of 7.3? |

| | |

| |YES |

| |. |
